Questions Asked in Limb Salvage Interview
Q 1. Describe your experience with different limb salvage techniques.
My experience with limb salvage techniques spans a wide range of procedures, all aimed at preserving the limb while addressing the underlying pathology, typically bone tumors or severe trauma. This includes various osteotomies (surgical cutting of bone) to correct deformities, the use of bone grafts (either autologous – from the patient’s own body – or allografts – from a donor) to fill bone defects, and the application of different external fixation devices for stabilization and fracture healing. I’ve also extensively utilized intramedullary nailing (inserting a rod inside the bone) and plate and screw fixation for fracture management within the context of limb salvage. Furthermore, my expertise extends to complex reconstructions involving the use of free tissue transfer (free flaps), discussed in more detail later. Each technique’s selection depends on the individual patient’s condition, the extent of the damage, and the overall goal of functional preservation.
For instance, a patient with a large bone tumor in the femur might require a wide resection (removal of a significant portion of the bone) followed by reconstruction using a custom-made prosthesis and possibly a vascularized fibular graft to replace the resected bone and improve structural integrity. In contrast, a patient with a complex fracture might benefit from external fixation initially, followed by intramedullary nailing once the bone is sufficiently stable. The choice is always personalized and carefully considered.
Q 2. Explain the indications and contraindications for limb salvage surgery.
The decision to pursue limb salvage hinges on several factors. Indications include cases where the tumor or trauma is localized, amenable to resection and reconstruction, leaving sufficient soft tissue to cover the reconstructive elements. A patient’s overall health, age, and functional expectations also play critical roles. For example, a young, healthy patient with a localized bone tumor in the tibia is a good candidate for limb salvage, whereas an elderly patient with extensive soft tissue damage and multiple comorbidities might be a better candidate for amputation.
Contraindications include situations where the extent of the disease or injury is too severe to allow for adequate reconstruction, resulting in a high risk of complications like infection, non-union (failure of the bone to heal), or limb failure. Extensive soft tissue loss that cannot be adequately replaced, extensive vascular compromise jeopardizing limb viability, and severe infection are all significant contraindications. We always weigh the potential benefits against the risks meticulously before proceeding with a limb salvage procedure.
Q 3. What are the major complications associated with limb salvage procedures?
Limb salvage procedures, while life-changing for many, carry a risk of several major complications. Infection is a significant concern, particularly in cases involving open fractures or extensive bone resection. Nonunion, the failure of the bone to heal, can lead to prolonged disability and potential need for revision surgery. Malunion, where the bone heals in an incorrect position, can cause deformity and functional limitations. Hardware failure, particularly with implants like plates and screws, can require further surgery. Complex regional pain syndrome (CRPS), a debilitating chronic pain condition, can occur after limb salvage surgery, particularly following trauma. Deep venous thrombosis (DVT) and pulmonary embolism (PE) are also possible risks, demanding careful attention to prophylactic measures.
Imagine a scenario where a patient undergoes limb salvage after a severe tibia fracture. If the bone doesn’t heal properly (nonunion), it might require bone grafting or a different surgical approach to stabilize the fracture. If infection develops post-operatively, it can delay healing, possibly compromising limb viability. These complications underscore the need for meticulous surgical technique, appropriate post-operative care, and diligent monitoring.
Q 4. How do you manage infection in limb salvage patients?
Managing infection in limb salvage patients is critical and requires a multi-pronged approach. Prompt recognition is paramount; any signs of infection, such as fever, localized swelling, redness, or drainage, are immediately investigated. Treatment typically involves surgical debridement (removal of infected tissue), aggressive antibiotic therapy guided by culture and sensitivity testing, and meticulous wound care. In severe cases, external fixation may be necessary to provide stability while allowing for better wound management and monitoring. Sometimes, a staged approach is necessary, with initial debridement and infection control followed by reconstructive surgery once the infection is under control. In extreme cases, despite best efforts, amputation might become necessary to save the patient’s life.
For example, if a patient develops a deep infection post-operatively following a limb salvage procedure involving a bone graft, immediate surgical debridement to remove the infected tissue is crucial. Intravenous antibiotics are administered, tailoring the choice to the specific bacteria identified in the culture. Close monitoring of clinical parameters and repeat cultures ensure the effectiveness of the treatment.
Q 5. Discuss your approach to preoperative planning for limb salvage.
Preoperative planning for limb salvage is meticulous and crucial for success. It begins with a thorough assessment of the patient’s overall health, including their medical history, comorbidities, and functional status. Detailed imaging studies, such as CT scans, MRIs, and X-rays, are essential to define the extent of the disease or injury, assess bone and soft tissue involvement, and plan the surgical approach. We collaborate with oncologists (for tumor cases) and other specialists as needed. We meticulously assess vascularity and nerve supply to ensure adequate perfusion and function of the salvaged limb. 3D-printed models of the bone are often used to plan complex reconstructions. Finally, we discuss realistic expectations and potential complications with the patient and their family to ensure informed consent.
A good example is a patient with a large bone tumor requiring a significant bone resection. We would use imaging to assess the tumor’s margins, vascularity, and relationship to adjacent structures. Then, we’d discuss different reconstruction options like bone grafts, prosthetics, or combinations thereof. The patient’s age, health, and functional demands influence this choice. We’d even utilize 3D modeling to virtually plan the reconstruction before the surgery.
Q 6. Describe your experience with free flap surgery in limb salvage.
Free flap surgery plays a vital role in complex limb salvage procedures, particularly when significant soft tissue defects exist. It involves microsurgical transfer of a tissue flap, complete with its own blood supply, from a donor site (often the abdomen, thigh, or forearm) to the recipient site (the defect in the limb). This allows for reconstruction of large soft tissue defects, covering exposed bone, tendons, and implants, significantly reducing infection risk and improving limb function. My experience encompasses a range of free flaps, including the fibula free flap, commonly used for bone replacement, and muscle flaps for soft tissue reconstruction. The success of free flap surgery hinges on meticulous microsurgical technique to anastomose (reconnect) the blood vessels of the flap to those at the recipient site, ensuring adequate blood supply to the transferred tissue.
For instance, I recently used a free fibula flap to reconstruct a significant segmental bone defect in a patient who had sustained a devastating tibia fracture. This flap not only provided bone for structural support but also provided soft tissue coverage, improving wound healing and reducing the risk of infection. The microsurgical aspect was critical to ensure the long-term viability of the flap.
Q 7. How do you assess the functional outcome after limb salvage surgery?
Assessing functional outcome after limb salvage surgery involves a multi-faceted approach, combining objective and subjective measures. Objective measures include range of motion (ROM) assessment using goniometry, strength testing using dynamometry, and gait analysis using motion capture systems. Functional scales, such as the Musculoskeletal Tumor Society (MSTS) score for bone tumors, provide a standardized method for evaluating functional outcomes. Subjective measures include patient-reported outcome measures (PROMs) like questionnaires assessing pain levels, functional limitations, and quality of life. Radiographic evaluation helps determine the healing status of the bone and the stability of the implants. Regular follow-up visits are critical to monitor the patient’s progress, address any complications, and optimize functional outcomes.
In practice, we use a combination of these approaches. For example, we’d assess a patient’s ability to walk and climb stairs after tibia salvage, using gait analysis and functional scales to quantify their progress. We’d then assess their subjective experience of pain and limitations through questionnaires, tailoring our management strategy based on the combined objective and subjective data. Long-term follow-up allows for identification and management of any delayed complications such as CRPS.
Q 8. What are the key factors to consider when selecting a limb salvage technique?
Selecting a limb salvage technique is a complex decision requiring a multifactorial approach. We prioritize preserving the limb’s function and minimizing long-term complications. Key factors include the tumor’s location, size, and grade; the patient’s overall health and functional goals; the availability of adequate soft tissue and bone stock; and the potential for complications such as infection or nonunion.
- Tumor characteristics: A small, low-grade tumor in a distal location might allow for a less extensive procedure than a large, high-grade tumor close to the joint.
- Patient factors: A young, active patient might prefer a more extensive procedure to maintain function, while an older patient with comorbidities might opt for a less invasive approach.
- Soft tissue and bone status: Sufficient soft tissue coverage is crucial for wound healing. Inadequate bone stock might necessitate bone grafting or transport techniques.
- Surgical expertise: The availability of specialized surgical techniques and expertise (e.g., microsurgery for free flaps) influences the chosen approach.
For example, a patient with a small chondrosarcoma in the tibia might be a candidate for wide resection and reconstruction with an allograft, while a patient with a large, aggressive osteosarcoma might require a more extensive resection with rotationplasty or even amputation.
Q 9. How do you manage bone defects in limb salvage procedures?
Managing bone defects in limb salvage requires careful consideration of defect size, location, and the patient’s overall health. Multiple strategies exist, often combined for optimal results. These include:
- Bone grafting: Autografts (from the patient’s own bone) are ideal but limited in size. Allografts (from a donor) are an alternative, but carry a higher risk of disease transmission or nonunion. We carefully select the type of graft based on the defect size and location.
- Bone lengthening: Distraction osteogenesis, a technique using an external fixator to gradually lengthen a bone, can be used to bridge defects. This requires meticulous planning and execution.
- Custom implants: 3D-printed implants or custom-made metallic prostheses can effectively fill larger bone defects. They need to be precisely designed to integrate with the surrounding bone.
- Vascularized bone grafts: These provide better healing potential than non-vascularized grafts, especially in cases of compromised blood supply. They involve transferring a segment of bone with its own blood supply to the defect site.
Consider a scenario of a large tibial defect after resection of a malignant tumor. A combination approach, such as using a vascularized fibular graft to fill part of the defect and then lengthening the remaining bone using distraction osteogenesis, might be necessary to achieve a functional limb.
Q 10. What is your experience with bone transport techniques?
Bone transport, also known as distraction osteogenesis, is a powerful technique to regenerate bone and bridge large defects. My experience includes both the application of the technique in various locations (femur, tibia, humerus) and the management of its potential complications. The process involves creating an osteotomy (bone cut), applying an external fixator, and then gradually distracting (separating) the bone segments at a controlled rate. New bone forms in the gap, effectively lengthening the bone and filling the defect. I’ve found it particularly useful in cases where there’s insufficient bone stock for traditional grafting techniques.
I have significant experience managing the complications associated with bone transport, such as pin site infections, delayed union, and nonunion, ensuring that our patients receive the best possible outcomes. Precise planning, meticulous execution, and diligent postoperative care are essential for success. We routinely monitor patients using radiographs to assess bone regeneration progress and to identify any potential problems early on.
Q 11. Explain your approach to the management of soft tissue defects in limb salvage.
Soft tissue defects are a significant challenge in limb salvage. Management depends on the defect’s size, location, and the patient’s overall health. Our approach is often multidisciplinary, involving plastic surgeons and other specialists.
- Local flaps: These involve repositioning nearby tissue to cover the defect. They are useful for smaller defects and are associated with lower morbidity than free flaps.
- Free flaps: These involve transferring tissue with its own blood supply from a distant site (e.g., latissimus dorsi, radial forearm). They offer greater versatility for larger defects, but they require microsurgical expertise and carry a higher risk of flap failure.
- Skin grafts: These are useful for covering relatively superficial defects. However, they may be limited in their ability to cover complex defects or areas with significant underlying tissue loss.
For instance, a large soft tissue defect following a wide resection of a tumor might necessitate the use of a free muscle flap to fill the defect, followed by a skin graft to cover the muscle flap. The choice of flap depends on many factors, including the defect’s size, location, and the availability of suitable donor sites.
Q 12. How do you assess vascularity in potential recipient sites for limb salvage?
Assessing vascularity in potential recipient sites is crucial for successful limb salvage, particularly when using free flaps. We employ a variety of techniques:
- Clinical examination: Assessing skin temperature, capillary refill time, and the presence of pulses helps provide an initial assessment of perfusion.
- Doppler ultrasound: This non-invasive technique measures blood flow in vessels, helping to identify areas with adequate perfusion.
- Angiography: This imaging technique provides detailed visualization of blood vessels, allowing for precise identification of suitable recipient vessels.
- Intraoperative assessment: Direct visualization of vessels during surgery is essential to ensure adequate blood flow before anastomosis (connecting) the vessels.
For example, before transferring a free fibula flap for reconstruction, we meticulously assess the blood vessels of the recipient site (usually the tibia) using Doppler ultrasound and intraoperative angiography to ensure there’s adequate blood supply to support the graft.
Q 13. Describe your experience with different types of external fixation devices.
My experience encompasses a wide range of external fixation devices, each with specific advantages and disadvantages. The choice depends on the fracture pattern, bone quality, and patient factors. I frequently use:
- Monolateral frames: These are simpler and less bulky than circular frames, suitable for relatively simple fractures. They are easier to apply and remove.
- Circular frames: These provide greater stability and control, especially for complex fractures or bone transport. They allow for precise adjustments and are good for correcting angular and rotational deformities.
- Hybrid frames: Combining features of both monolateral and circular frames, offering a balance of stability and ease of use.
The selection of specific components (pins, rods, clamps) also depends on the individual case. Proper pin placement is critical to ensure stability and minimize pin loosening or infection. Regular monitoring and adjustments are essential during the healing process.
Q 14. Discuss the role of imaging in limb salvage surgery.
Imaging plays a pivotal role throughout the limb salvage process, from initial diagnosis to postoperative monitoring. Different modalities provide complementary information:
- Plain radiographs: Essential for initial evaluation of bone lesions, fracture patterns, and for monitoring bone healing during fracture treatment or bone transport.
- Computed tomography (CT): Provides detailed three-dimensional images of bone, allowing precise assessment of tumor extent and bone defects. This information is crucial for surgical planning.
- Magnetic resonance imaging (MRI): Excellent for soft tissue assessment, helping to identify the extent of tumor involvement in soft tissues and to evaluate the viability of potential flap donor sites.
- Angiography: Provides detailed images of blood vessels, vital for planning vascularized bone grafts or free flaps and monitoring perfusion postoperatively.
For instance, pre-operative CT scans allow precise three-dimensional modeling of bone defects, which is critical for designing custom implants or planning bone transport procedures. Post-operative radiographs allow close monitoring of bone healing and detection of any complications such as non-union or infection.
Q 15. What are the challenges in managing patients with complex limb injuries requiring salvage?
Managing patients with complex limb injuries requiring salvage presents a unique set of challenges. These are often multifactorial, encompassing the severity of the initial trauma, the patient’s overall health, and the potential for complications.
- Infection: Limb salvage often involves extensive soft tissue damage and the use of implanted hardware, increasing the risk of infection, which can be life-threatening and necessitate further surgery or even amputation.
- Nonunion: The failure of bone fragments to heal properly is a significant concern. This can lead to chronic pain, instability, and functional limitations.
- Malunion: Bones may heal in an incorrect position, resulting in deformity and compromised function. Corrective surgery may be necessary.
- Complex Regional Pain Syndrome (CRPS): This debilitating condition can develop after limb trauma and is characterized by chronic pain, swelling, and changes in skin color and temperature. Management is challenging and often requires a multidisciplinary approach.
- Compromised Vascularity: Severely injured limbs may have reduced blood supply, making healing more difficult and increasing the risk of tissue loss.
- Patient-Related Factors: Pre-existing conditions such as diabetes, obesity, and smoking significantly impact healing and increase the risk of complications.
For example, a patient with a severely comminuted tibia fracture (bone broken into multiple pieces) and extensive soft tissue damage might require multiple surgeries, including external fixation, bone grafting, and soft tissue reconstruction, to achieve limb salvage. Each step introduces further risks and complexities.

Q 17. What are your preferred methods for pain management in limb salvage patients?
Pain management in limb salvage patients is paramount and requires a multimodal approach tailored to individual needs. It’s not a ‘one-size-fits-all’ solution.
- Pharmacological Management: This may include a combination of analgesics, such as opioids for acute pain, and non-steroidal anti-inflammatory drugs (NSAIDs) for inflammation. We carefully manage opioid use to prevent dependence and adverse effects.
- Regional Anesthesia: Techniques like nerve blocks or continuous peripheral nerve catheters can provide effective pain relief, especially in the immediate postoperative period.
- Neuromodulation: Spinal cord stimulation or peripheral nerve stimulation can be beneficial for chronic pain that doesn’t respond well to other treatments.
- Physical Therapy: Early mobilization and targeted exercises are crucial, not only for regaining function but also for managing pain by improving circulation and reducing stiffness.
- Psychological Interventions: Addressing the psychological impact of chronic pain is vital. This may involve cognitive behavioral therapy (CBT) or other psychological therapies.
For example, a patient with CRPS might benefit from a combination of medication, regional anesthesia, physical therapy, and psychological counseling to effectively manage their pain.
Q 18. How do you coordinate care with other members of the healthcare team?
Coordinating care with other healthcare professionals is crucial for optimal outcomes in limb salvage. This requires clear communication, shared goals, and a well-defined care plan.

- Prosthetists and Orthotics Specialists: In some cases, prosthetics or orthotics may be necessary to augment limb function, requiring coordinated care.
Regular team meetings, comprehensive patient charts, and clear communication channels are essential to ensure everyone is on the same page.
Q 19. Describe your experience with rehabilitation protocols for limb salvage patients.
Rehabilitation is an integral part of limb salvage, starting early in the recovery process. The protocols are highly individualized, adapting to the specific needs of each patient and the nature of their injury.
- Early Mobilization: Gentle range-of-motion exercises and weight-bearing as tolerated, starting shortly after surgery to minimize stiffness and promote healing.
- Progressive Strengthening: Gradual increase in strength training exercises tailored to the affected limb, using appropriate resistance and ensuring proper form.
- Functional Training: Exercises focused on regaining functional abilities, such as walking, climbing stairs, and performing daily activities.
- Wound Care: Close monitoring and treatment of wounds, including dressing changes, to promote healing and prevent infection.
- Pain Management: Ongoing pain management strategies to minimize discomfort and facilitate participation in therapy.
- Adaptive Equipment: Use of assistive devices, such as crutches, walkers, or braces, to aid mobility and support the limb.
For example, a patient with a complex ankle fracture might begin with simple range-of-motion exercises and progress to weight-bearing exercises on a specialized treadmill, eventually working towards activities like walking and running.
Q 20. What are the long-term outcomes you expect to see in limb salvage patients?
Long-term outcomes in limb salvage vary widely depending on the severity of the initial injury, the patient’s overall health, and the effectiveness of the treatment.
- Functional Outcomes: The primary goal is to restore as much function as possible to the affected limb. This might include regaining full range of motion, strength, and the ability to perform daily activities.
- Pain Management: Many patients experience some degree of chronic pain, requiring ongoing management strategies. The aim is to minimize pain and improve quality of life.
- Quality of Life: Improved quality of life is a key indicator of successful limb salvage. Patients should be able to participate in their desired activities and maintain their independence.
- Return to Work/Activities: Many patients are able to return to work or their previous level of activity, although this may take considerable time and effort.
- Complications: The risk of long-term complications, such as infection, nonunion, or CRPS, must be considered.
While some patients achieve almost complete recovery, others may have persistent limitations in function or ongoing pain. Regular follow-up visits are essential to monitor progress and address any emerging issues.
Q 21. How do you handle unforeseen surgical complications during limb salvage?
Unforeseen surgical complications can occur during limb salvage procedures. Effective management requires a calm, systematic approach, emphasizing patient safety and prompt action.
- Immediate Response: Rapid assessment of the complication, focusing on its nature, severity, and potential impact on the patient.
- Surgical Intervention: If necessary, immediate surgical intervention to address the complication, such as controlling bleeding, addressing infection, or correcting a malunion.
- Medical Management: Implementing medical management strategies, such as antibiotics for infection or pain medication to manage postoperative pain.
- Open Communication: Transparent communication with the patient and their family, explaining the complication, the steps taken to address it, and the potential impact on the treatment plan.
- Revised Treatment Plan: Modification of the treatment plan to accommodate the complication, potentially requiring additional surgeries or a shift in the rehabilitation strategy.
- Documentation: Meticulous documentation of the complication, the management steps taken, and the patient’s response is essential.
For example, encountering unexpected infection during surgery might necessitate immediate surgical debridement (removal of infected tissue), intravenous antibiotics, and a temporary delay in the planned reconstructive procedures. Transparency and clear communication with the patient are paramount during these challenging situations.
Q 22. Discuss your understanding of the different types of bone tumors that may require limb salvage.
Limb salvage surgery aims to preserve a limb threatened by a tumor, rather than resorting to amputation. Several types of bone tumors necessitate this approach. These can be broadly categorized as benign or malignant, with malignant tumors posing a greater threat and requiring more aggressive treatment.
- Benign Bone Tumors: These are non-cancerous and often slow-growing. Examples include osteochondromas (the most common benign bone tumor), giant cell tumors, and enchondromas. Treatment for these often involves surgical removal of the tumor, but the extent of surgery is typically less extensive than with malignant tumors.
- Malignant Bone Tumors: These are cancerous and can spread (metastasize) to other parts of the body. Osteosarcoma is the most common primary malignant bone tumor, particularly affecting adolescents and young adults. Ewing sarcoma and chondrosarcoma are other significant malignant bone tumors. These require aggressive surgical resection, often combined with chemotherapy and/or radiation therapy, to maximize the chances of eliminating cancerous cells.
The specific type of bone tumor dictates the surgical approach and the extent of the resection needed for limb salvage. For example, a small, well-defined benign tumor might only require curettage (scooping out the tumor), whereas a large, aggressive malignant tumor might require wide resection (removal of a larger section of bone) along with reconstruction.
Q 23. How do you assess the patient’s overall health and fitness for limb salvage surgery?
Assessing a patient’s fitness for limb salvage surgery is crucial and involves a multidisciplinary approach. It’s not just about the tumor; it’s about the whole patient. We consider factors such as:
- Cardiac Function: Major surgeries like limb salvage are demanding on the heart. We evaluate cardiac health through tests like EKGs and echocardiograms to ensure the patient can withstand the procedure.
- Pulmonary Function: Adequate lung capacity is essential for recovery. Spirometry testing helps assess lung function and identify any potential risks of post-operative complications like pneumonia.
- Renal Function: Kidney function is crucial for processing anesthetic agents and eliminating waste products. Blood tests such as creatinine and BUN levels are checked to ensure healthy kidney function.
- Overall Health: Existing conditions like diabetes, hypertension, or immune deficiencies can influence surgical risk. These conditions need to be managed optimally before surgery.
- Nutritional Status: Proper nutrition is critical for wound healing. A nutritional assessment might be needed to address any deficiencies.
- Tumor Characteristics: The size, location, and aggressiveness of the tumor play a vital role in determining the feasibility of limb salvage. Imaging studies (X-rays, CT scans, MRIs) are paramount in determining this.
Ultimately, a multidisciplinary team—including oncologists, surgeons, anesthesiologists, and rehabilitation specialists—collaborates to determine the patient’s suitability for limb salvage. A patient’s overall health and the anticipated recovery process are carefully weighed against the potential risks of the surgery.
Q 24. What are the ethical considerations in deciding on limb salvage versus amputation?
The decision between limb salvage and amputation is fraught with ethical considerations. The primary ethical principle guiding this decision is patient autonomy—respecting the patient’s wishes and values. This requires open and honest communication with the patient and their family, fully explaining the risks, benefits, and limitations of each option.
Further ethical considerations include:
- Beneficence: We aim to act in the patient’s best interests. This includes considering functional outcomes, quality of life, and the long-term impact of each choice. For example, while limb salvage might preserve the limb, it might also lead to more extensive rehabilitation and a longer recovery time.
- Non-maleficence: We must avoid causing harm. This involves carefully assessing the potential complications of each option, including surgical risks, infection risks, and the potential for recurrence of the tumor.
- Justice: Equal access to high-quality care, irrespective of socioeconomic status, is critical. This means ensuring that patients have access to the most appropriate treatment, regardless of their financial situation.
Shared decision-making, which involves a collaborative discussion between the healthcare team and the patient, is crucial. This ensures that the patient feels empowered to make an informed choice that aligns with their values and goals.
Q 25. What are the advancements in limb salvage technology that you are aware of?
Significant advancements have revolutionized limb salvage. These advancements include:
- Improved Imaging Techniques: Advanced MRI and CT scans offer better visualization of tumors, allowing for more precise surgical planning and reducing the risk of leaving behind cancerous cells.
- Minimally Invasive Techniques: Arthroscopy and other minimally invasive approaches minimize trauma, leading to faster recovery times and reduced complications.
- 3D-Printed Implants: Custom-designed implants, created using 3D printing technology, allow for more precise bone reconstruction and improved functional outcomes. These implants can be tailored to the unique anatomy of each patient.
- Advances in Reconstruction: New techniques using bone grafts, vascularized fibular grafts (transferring a section of fibula bone with its blood supply), and allografts (bone from a donor) allow for the reconstruction of large bone defects.
- Targeted Therapies: Advances in chemotherapy and radiation therapy have improved the ability to control tumor growth, increasing the likelihood of successful limb salvage. These treatments can be used before, during, and after surgery.
- Biomaterials: The development of new biocompatible materials for implants and bone grafts enhances integration with the body and minimizes the risk of rejection.

Q 27. Describe a challenging case in limb salvage and how you approached it.
One particularly challenging case involved a young adult with a large, high-grade osteosarcoma in the proximal tibia (upper part of the shin bone). The tumor was extensive, encroaching upon the knee joint. The initial imaging suggested that amputation might be the only option. However, the patient was very determined to retain their leg.
Our multidisciplinary team, including oncologists, radiologists, and orthopedic surgeons, carefully reviewed the imaging data and conducted further investigations. We found that a limb salvage procedure was feasible. We planned a complex surgery involving a wide resection of the tumor, which included a significant portion of the tibia. The defect was reconstructed using a combination of a custom-made 3D-printed titanium implant and a vascularized fibular graft to restore bone length and stability.
Post-operatively, the patient underwent intense rehabilitation, gradually regaining mobility and strength. Chemotherapy was also implemented to mitigate recurrence. After several months, the patient was able to walk without assistance and resume many of their daily activities. This case highlighted the importance of a multidisciplinary team, technological advancements, and patient resilience in achieving successful limb salvage outcomes, even in what initially seemed like an impossible situation.
Q 28. What are your salary expectations for this position?
