Overview

Congenital fibular hemimelia (FH) is a challenging condition to manage, especially when it involves severe ankle malalignment. The SUPERankle procedure has emerged as a promising solution to address this issue. According to a study published on PubMed, this procedure can significantly improve ankle alignment and provide durable stability in patients with severe FH (Source: PubMed). This study matters because it offers new hope for children born with this condition, allowing them to lead more active and independent lives.

The SUPERankle procedure is a complex surgical intervention that aims to correct ankle malalignment and provide a stable platform for further limb lengthening procedures. As a senior medical writer and orthopedic surgeon with expertise in limb lengthening and distraction osteogenesis, I can attest to the importance of this study in advancing our understanding of FH management.

What This Study Examined

This study examined the effectiveness of the SUPERankle procedure in correcting ankle malalignment in 17 children with severe FH, affecting 19 limbs. The researchers evaluated the patients' ankle alignment and stability before and after the procedure, as well as at a follow-up of 63.0±19.7 months. They used various radiographic measurements, including the mLDTA, mTCA, and mTCD, to assess the degree of correction achieved.

Why This Matters for Patients

The results of this study are significant for patients with severe FH because they demonstrate the potential of the SUPERankle procedure to improve ankle alignment and stability. This, in turn, can enhance the patients' overall quality of life, allowing them to participate in activities that might have been challenging or impossible due to their condition. The study's findings also highlight the importance of careful patient selection and meticulous surgical technique to achieve optimal outcomes.

Medical Background

Congenital fibular hemimelia is a rare condition characterized by the absence or underdevelopment of the fibula. This can lead to various deformities, including ankle malalignment, equinovalgus foot deformity, and tibial curvature. The SUPERankle procedure is designed to address these deformities by correcting the ankle alignment and providing a stable platform for further surgical interventions, such as external fixator application or intramedullary nail insertion.

How the Procedure Works

The SUPERankle procedure involves a combination of osteotomies and distraction osteogenesis to correct the ankle malalignment and deformities. The procedure is typically performed in a staged manner, with the initial surgery focusing on correcting the ankle alignment and subsequent surgeries addressing any remaining deformities or length discrepancies.

Who Is a Candidate?

Candidates for the SUPERankle procedure are typically children with severe FH, characterized by significant ankle malalignment and deformities. The ideal candidate should have a sufficient amount of bone stock to allow for stable fixation and bone regeneration. Patients with more mild forms of FH may not require such an extensive procedure, and their treatment can be tailored to address their specific needs.

Tibial Hemimelia Guide

Overview Tibial hemimelia is a rare congenital limb deficiency characterized by variable tibial absence, knee instability, and ankle deformity. This condition affects approximately 1 in 100,000 births and can have a significant impact on a child's mobility and quality of life. A recent study published on PubMed proposed a novel classification system for tibial hemimelia, which prioritizes quadriceps mechanism integrity and joint stability (Source: PubMed). The study examined 566 patients with tibial hemimelia who underwent limb reconstruction surgery between 1990 and 2020. The goal of the study was to develop a classification system that would guide surgical decision-making and improve outcomes for patients with this condition. The proposed classification system takes into account the severity of the tibial deficiency, as well as the integrity of the quadriceps extensor mechanism and the stability of the knee joint. What This Study Examined The study examined the effectiveness of a novel classification system for tibial hemimelia in guiding surgical decision-making and improving outcomes for patients. The classification system is based on five domains: tibial morphology, quadriceps mechanism integrity, knee stability and active extension, ankle stability and distal support, and expected evolution during growth. Why This Matters for Patients This study matters for patients with tibial hemimelia because it provides a framework for surgeons to make informed decisions about the best course of treatment. The classification system takes into account the unique characteristics of each patient's condition, including the severity of the tibial deficiency and the integrity of the quadriceps extensor mechanism. By using this classification system, surgeons can develop a personalized treatment plan that addresses the individual needs of each patient and improves the chances of a successful outcome. Medical Background Tibial hemimelia is a congenital limb deficiency that is characterized by a partial or complete absence of the tibia. This condition can also involve knee instability and ankle deformity. The goal of treatment is to restore weight-bearing function and mobility to the affected limb. The treatment of tibial hemimelia typically involves a combination of orthopedic surgery and orthotics. The type and extent of surgery required will depend on the severity of the condition and the individual needs of the patient. In some cases, limb lengthening or osteotomy may be necessary to restore alignment and length to the affected limb. How the Procedure Works The treatment of tibial hemimelia typically involves a combination of orthopedic surgery and orthotics. The surgeon will use a variety of techniques, including limb lengthening, osteotomy, and external fixation, to restore alignment and length to the affected limb. Who Is a Candidate?

Dedifferentiated Chondrosarcoma of Distal Femur – Diagnosis and Double‑Barrel Fibular Graft Reconstruction Guide

Overview Dedifferentiated chondrosarcoma (DCS) of the distal femur is an uncommon, aggressive bone cancer that often presents with pain, swelling, and rapid growth. A recent case report described a 48‑year‑old woman whose tumor required a limb‑salvage operation using a double‑barrel autologous fibular graft (Source: PubMed / Europe PMC). This guide translates that experience into clear, patient‑focused information, highlighting why accurate diagnosis, timely surgery, and modern reconstruction techniques matter for anyone facing this disease. The lessons from this case are relevant not only to patients diagnosed with DCS but also to anyone who experiences unexplained knee pain, swelling, or radiologic findings suggestive of an aggressive bone lesion. Understanding the diagnostic challenges, surgical options, and realistic expectations after reconstruction can empower patients to make informed decisions and collaborate effectively with their orthopedic oncology team. What This Study Examined The report examined a single patient with a distal‑femoral DCS. It detailed the imaging work‑up, the difficulty of obtaining a definitive diagnosis from core needle biopsy, rapid tumor progression on serial scans, and the eventual decision to perform wide excision followed by limb‑salvage reconstruction using a double‑barrel fibular graft. Why This Matters for Patients Because DCS combines a low‑grade cartilage tumor with a high‑grade sarcomatous component, missing the aggressive part on biopsy can delay life‑saving treatment. Moreover, the reconstruction technique described—double‑barrel fibular graft—offers an alternative to endoprosthetic replacement, preserving native bone and potentially reducing long‑term complications. Medical Background Dedifferentiated chondrosarcoma is a biphasic malignancy that contains both a well‑differentiated cartilage‑producing tumor and a suddenly appearing high‑grade spindle‑cell sarcoma. It most often arises in the femur, pelvis, or humerus and carries a poorer prognosis than conventional chondrosarcoma. The term DCS reflects the abrupt transition from a low‑grade to a high‑grade component, which can be missed on small tissue samples. When the tumor involves the distal femur—the lower part of the thigh bone near the knee—patients typically notice progressive pain, swelling, and reduced range of motion. Radiographs may show a lytic (bone‑destroying) lesion, while advanced imaging such as MRI or CT can reveal a heterogeneous mass with a sizable soft‑tissue component. How the Procedure Works The double‑barrel fibular graft technique involves harvesting two segments of the patient’s own fibula (the smaller bone of the lower leg). These segments are placed side‑by‑side (hence “double‑barrel”) to fill the bone defect left after tumor removal. The graft is secured with screws or a plate, and the surrounding soft tissue is reconstructed to protect the joint. Because the graft is autologous (autologous), it integrates with the host bone, promoting new bone formation and potentially allowing the patient to retain a more natural limb length. Who Is a Candidate? Ideal candidates are patients with a high‑grade bone sarcoma confined to a single bone segment, sufficient healthy surrounding soft tissue, and adequate vascular supply to support graft healing. Age, overall health, and personal goals (e.g., desire to avoid a large prosthetic implant) also influence candidacy. In the reported case, the patient was a relatively young, otherwise healthy adult with localized disease, making her a good candidate for this limb‑salvage approach. Clinical Summary Procedure: Wide excision of distal‑femoral DCS followed by reconstruction with a double‑barrel autologous fibular graft. Typical Duration: 3–5 hours of operative time, depending on tumor size and reconstruction complexity. Recovery: Hospital stay of 5–7 days; weight‑bearing is usually limited for 8–12 weeks while the graft consolidates. Success Rate (general): Limb‑salvage surgery for distal femur sarcoma achieves local control rates of 70‑85% and long‑term functional scores comparable to endoprosthetic replacement, though specific data for double‑barrel fibular grafts are limited to case series. Study Methodology Because the source is a single‑case report, the study design is descriptive rather than comparative. The patient was followed from initial presentation through 6 months post‑operative imaging to assess for recurrence. Patient Selection Criteria The report focused on one adult (48 years) who presented with progressive distal‑femoral pain and an imaging‑defined aggressive lesion. Core needle biopsy was inconclusive, prompting repeat imaging and eventual wide excision. No other patients were included. Outcome Measures The primary outcomes were histopathologic confirmation of DCS, radiographic evidence of graft incorporation, and absence of local recurrence at 6 months. Secondary outcomes included intra‑operative blood loss, length of hospital stay, and early postoperative complications. Results & Findings Histology revealed the classic biphasic pattern of DCS: a low‑grade chondroid area transitioning abruptly to a high‑grade spindle‑cell sarcoma. Wide surgical margins were achieved, and the double‑barrel fibular graft was secured without intra‑operative fracture of the remaining femur. Key Outcomes All surgical margins were negative (R0 resection), indicating complete tumor removal. At 6 months, plain radiographs and MRI showed satisfactory graft integration with callus formation and no radiographic signs of recurrence. The patient regained functional use of the leg, ambulating with a cane by month four and without assistive devices by month six. Complications & Risks The case report did not describe major complications, but the authors noted typical risks associated with limb‑salvage surgery and autologous fibular harvest, including: Donor‑site morbidity such as ankle instability or sensory changes. Non‑union or delayed union of the fibular graft. Infection of the surgical site. Hardware irritation or failure. Local recurrence of DCS, which remains a lifelong concern given the tumor’s aggressive nature. Key Takeaways for Patients Dedifferentiated chondrosarcoma is a high‑grade cancer; accurate diagnosis often requires multiple biopsies and careful imaging review. Early, wide surgical excision offers the best chance of local control. Double‑barrel fibular graft reconstruction can preserve the patient’s own bone, avoid a large prosthetic, and provide good functional results when performed by an experienced orthopedic oncologist. Recovery involves limited weight‑bearing for several months; physical therapy is essential to regain strength and gait. Patients should ask their surgeon about: What specific margins will be achieved and how they are confirmed? What are the alternatives (endoprosthesis vs. autograft) and their long‑term pros/cons? How will donor‑site pain be managed and what activities should be avoided after fibular harvest? What surveillance schedule is recommended to detect recurrence early? Frequently Asked Questions What is dedifferentiated chondrosarcoma and how does it differ from regular chondrosarcoma? Dedifferentiated chondrosarcoma (DCS) is a two‑component tumor that starts as a low‑grade cartilage cancer but suddenly develops a high‑grade sarcoma, making it much more aggressive than conventional chondrosarcoma. How can doctors be sure they have diagnosed DCS accurately? Diagnosis relies on a combination of imaging (MRI, CT) that shows heterogeneous features and a tissue biopsy that demonstrates the abrupt transition between cartilage and high‑grade spindle‑cell areas. Sometimes more than one biopsy is needed. Why might a surgeon choose a double‑barrel fibular graft instead of a knee prosthesis? The graft uses the patient’s own bone, avoids a large metal implant, and can provide better long‑term durability with fewer risks of prosthetic wear or loosening, especially for younger, active patients. What is the expected recovery timeline after this type of limb‑salvage surgery? Most patients stay in the hospital for a week, begin gentle range‑of‑motion exercises within a few days, and stay non‑weight‑bearing for 8–12 weeks. Full return to normal activities usually occurs by 4–6 months, depending on graft healing. Will the tumor ever come back after surgery? Because DCS is aggressive, there is a lifelong risk of recurrence. Ongoing surveillance with periodic MRI or CT scans, as recommended by the oncology team, is essential for early detection.

Limb Lengthening After Fibular Deficiency: A Case Study on Salvage Surgery

Overview This case study presents a successful limb salvage approach for a patient with congenital fibular deficiency, a rare condition causing limb deformities and length discrepancies. The patient had a challenging medical history, including a previous corrective osteotomy and a persistent nonunion of the tibia bone, which resulted in an inability to walk. The study highlights a comprehensive treatment strategy that addressed both biological and mechanical aspects, leading to a remarkable recovery. The patient's journey showcases the complexity of managing congenital fibular deficiency, especially when prior treatments have not achieved the desired outcomes. By detailing the surgical techniques and long-term results, this study offers valuable insights for orthopedic surgeons and patients facing similar challenges. What This Study Examined Researchers focused on a 12-year follow-up of a male patient who underwent a series of procedures to address a chronic non-healing fracture of the tibia, a common complication in fibular deficiency cases. The study aimed to demonstrate the effectiveness of a personalized treatment plan that considered both bone healing and mechanical stability. Why This Matters for Patients For individuals with congenital fibular deficiency, this study provides hope for improved limb function and quality of life. It showcases a successful approach to limb salvage, even in complex cases with previous treatment failures. The long-term success of this patient's treatment highlights the potential for patients to regain mobility and independence. Medical Background Congenital fibular deficiency is a rare birth defect where the fibula, a bone in the lower leg, is partially or completely absent. This condition leads to limb-length discrepancies, ankle and foot deformities, and soft tissue imbalances. The severity of the deformity can vary, impacting the patient's ability to walk and perform daily activities. Osteotomy is a common procedure to correct limb deformities. It involves cutting and reshaping the bone to realign it, often requiring distraction osteogenesis techniques. In some cases, external fixators or intramedullary nails are used to stabilize and lengthen the bone. However, bone healing and regeneration can be unpredictable, especially in patients with congenital fibular deficiency. How the Procedure Works Limb lengthening and deformity correction in congenital fibular deficiency often involve a combination of surgical techniques. The process typically includes: Osteotomy: The surgeon cuts the bone at the desired location to correct the deformity or create a site for lengthening. Distraction Osteogenesis: This technique gradually lengthens the bone by applying a controlled force. External fixators or intramedullary devices are used to stabilize the bone during the lengthening process. Bone Regeneration: As the bone is lengthened, new bone tissue forms in the gap, eventually consolidating and healing. Mechanical Stability: Ensuring the lengthened bone is stable is crucial. This may involve the use of internal or external fixation devices until the bone heals. Who Is a Candidate? Patients with congenital fibular deficiency who have limb-length discrepancies, ankle deformities, or functional impairments may be candidates for limb lengthening and deformity correction. The procedure is typically recommended for those who have completed their growth, as it can help improve mobility and quality of life. Clinical Summary Procedure: Limb lengthening and deformity correction using osteotomy, distraction osteogenesis, and bone grafting. Typical Duration: The lengthening process can take several months, followed by a consolidation phase for bone healing. Recovery: Patients may require several weeks of hospitalization and a prolonged period of rehabilitation, including physical therapy. Success Rate (general): Success rates vary depending on the complexity of the case and patient factors. Complications can include infection, delayed union, or malalignment. Study Methodology This case study presents a single patient's journey over 12 years, detailing the surgical techniques and outcomes. The patient was a male who had previously undergone corrective osteotomy for congenital fibular deficiency, resulting in a chronic nonunion of the tibia. Patient Selection Criteria The patient was selected based on the complexity of his condition and the need for a comprehensive salvage strategy. The study aimed to demonstrate the feasibility of limb salvage in such challenging cases. Outcome Measures The primary outcome was the achievement of bone union and the patient's functional recovery. Secondary outcomes included the range of motion at the ankle and knee joints, pain levels, and the patient's ability to walk independently. Results & Findings The study reported the following key findings: Key Outcomes Bone union was successfully achieved after the comprehensive salvage strategy, which included multiple surgical procedures. A total limb lengthening of 78 mm was accomplished, addressing the limb-length discrepancy. At the 12-year follow-up, the patient had excellent functional outcomes, as evidenced by high ankle-hindfoot and knee scores. The patient regained the ability to walk independently without assistive devices and continued to work, demonstrating a significant improvement in quality of life. Complications & Risks The patient experienced a mild residual varus deformity of the proximal tibia, but this did not cause knee pain or instability. No progressive osteoarthritis was observed during the follow-up period. It is important to note that limb lengthening and deformity correction procedures carry inherent risks, including infection, delayed union, malalignment, and nerve or blood vessel damage. These complications were not reported in this specific case, but they are potential risks associated with such surgeries. Key Takeaways for Patients Limb salvage surgery can be a successful option for patients with congenital fibular deficiency and chronic nonunion, but it requires a personalized approach. The procedure may involve multiple stages, including osteotomy, distraction osteogenesis, bone grafting, and external fixation. Patients should expect a lengthy recovery process, including hospitalization and rehabilitation, to regain mobility and function. Discuss the potential risks and complications with your surgeon, including infection, delayed healing, and the need for additional procedures. Long-term follow-up is essential to monitor bone healing, functional recovery, and the potential for late complications. Frequently Asked Questions What is congenital fibular deficiency, and how does it affect the limb? Congenital fibular deficiency is a rare condition where the fibula bone in the lower leg is underdeveloped or missing. This leads to limb deformities, length discrepancies, and functional impairments, often requiring surgical correction. How does limb lengthening work in fibular deficiency cases? Limb lengthening involves cutting the bone (osteotomy) and gradually lengthening it using distraction osteogenesis techniques. External or internal fixation devices are used to stabilize the bone during the process. What are the risks of limb lengthening surgery? Common risks include infection, delayed bone healing, nerve or blood vessel damage, and the need for additional surgeries. Patients should discuss these risks with their surgeon and understand the potential complications. How long does it take to recover from limb lengthening surgery? Recovery time varies but typically involves several weeks of hospitalization and a prolonged rehabilitation period. Patients may require physical therapy and regular follow-up appointments to monitor progress and address any complications. Can limb lengthening surgery improve mobility and quality of life? Yes, in many cases, limb lengthening and deformity correction can significantly improve a patient's ability to walk and perform daily activities. The study highlights a successful case where the patient regained independence and continued to work, demonstrating the potential for an improved quality of life.

Fibular Tumor Surgery Guide: Outcomes, Risks, and What to Expect

Overview Primary fibular tumors are rare, yet they can be either benign (non‑cancerous) or malignant (cancerous). A recent 10‑year review from the National Cancer Institute, Cairo University, examined 22 patients who underwent surgical removal of these tumors. The study evaluated how different surgical techniques impacted recurrence, limb function, and survival, providing valuable data for anyone facing a fibular tumor diagnosis. Understanding the findings is crucial for patients, families, and clinicians because the fibula—although a “minor” bone—plays an essential role in knee and ankle stability and lies close to the common peroneal nerve. Mistakes in planning or execution can affect walking, balance, and quality of life. What This Study Examined The researchers retrospectively reviewed cases from January 2013 to January 2023, documenting tumor type, location (proximal vs. distal fibula), surgical approach (proximal fibulectomy, segmental resection, or above‑knee amputation), preservation of the peroneal nerve, postoperative complications, recurrence rates, and overall survival. Why This Matters for Patients Because fibular tumors are uncommon, most patients receive care based on limited evidence. This study supplies concrete statistics on recurrence (50 % overall) and survival (94 % at 1 year, 75 % at 2 years, 50 % at 3 years), helping patients set realistic expectations and facilitate informed discussions with their surgical team. Medical Background Fibular tumors can arise in the bone’s upper (proximal), middle (diaphysis), or lower (distal) portion. Common histologies include osteosarcoma, Ewing sarcoma, osteochondroma, and aneurysmal bone cyst. Symptoms often begin with painless swelling, but aggressive lesions may cause pain, fracture, or functional loss. How the Procedure Works Fibular tumor surgery aims to remove the entire tumor with a margin of healthy tissue while preserving nearby structures. Three main approaches were reported: Proximal fibulectomy: removal of the upper segment of the fibula, typically for tumors near the knee joint. Segmental resection: excising a middle portion of the bone, sometimes requiring a graft or prosthetic reconstruction to maintain leg length and stability. Above‑knee amputation: reserved for extensive, unresectable malignancies to achieve clear margins and prevent spread. When possible, surgeons attempt to protect the common peroneal nerve. In cases where the nerve must be sacrificed, patients may experience foot drop, requiring orthotic support or tendon transfer. Who Is a Candidate? Candidates include anyone diagnosed with a primary tumor of the fibula, regardless of age, who can tolerate surgery. Specific factors influencing choice of procedure are: Location of the tumor (proximal, middle, distal) Histologic aggressiveness (benign vs. malignant) Response to neoadjuvant (pre‑operative) chemotherapy or radiotherapy Patient’s overall health and functional goals Multidisciplinary evaluation—orthopedic oncology, medical oncology, radiology, and pathology—is standard before a definitive plan. Clinical Summary Procedure: Proximal fibulectomy, segmental resection, or above‑knee amputation for primary fibular tumors. Typical Duration: 2–4 hours, depending on tumor size and need for reconstruction. Recovery: Hospital stay 3–7 days; weight‑bearing may be delayed 4–8 weeks; full functional recovery 3–12 months. Success Rate (general): 50 % recurrence overall; 1‑year survival 94 %; 3‑year survival 50 % (as reported in the 10‑year Egyptian cohort). Study Methodology This was a retrospective cohort study reviewing medical records, radiographs, operative notes, and follow‑up data of 22 patients treated between 2013 and 2023 at a single tertiary cancer center. Patient Selection Criteria Inclusion required a histologically confirmed primary tumor of the fibula, primary surgical treatment at the institute, and a minimum of 12 months of postoperative follow‑up (median 32 months). Exclusion applied to metastatic disease to the fibula from another primary site and cases lacking complete imaging. Outcome Measures Primary outcomes were overall survival (OS) and event‑free survival (EFS). Secondary outcomes included local recurrence, limb‑sparing success, preservation of the common peroneal nerve, and postoperative complications such as infection, wound dehiscence, and functional instability. Results & Findings Among the 22 patients (median age 22 years, range 8–62), the proximal fibula was involved in 81.8 % of cases. Histologically, osteosarcoma accounted for 40.9 %, Ewing sarcoma 27.3 %, giant cell tumor 22.7 %, and chondrosarcoma 9.1 %. Key Outcomes Neoadjuvant therapy was administered in 68.2 % of patients, most commonly for high‑grade sarcomas. Surgical techniques: proximal fibulectomy (36.4 %), segmental resection (27.3 %), and above‑knee amputation (13.6 %). Common peroneal nerve was preserved in 68.2 % of cases; when sacrificed, patients required postoperative orthotic support. Overall recurrence rate was 50 % (11 of 22 patients); recurrence within osteosarcoma subgroup was 22.7 % (5 of 22 overall cases). Survival: 1‑year OS = 94.4 %, 2‑year OS = 75.4 %, 3‑year OS = 50.2 %; 1‑year EFS = 79.4 %, 2‑year = 56.3 %, 3‑year = 42.9 %. Complications & Risks Reported postoperative sequelae included: Wound infection (9 %); required antibiotics and occasional debridement. Neurological deficit due to peroneal nerve injury (approximately 13 % when the nerve could not be preserved). Joint instability: proximal resections can compromise lateral knee stability; distal resections affect ankle stability. Delayed bone healing or non‑union after segmental resection, especially when large gaps required grafting. Prosthetic complications in cases requiring endoprosthetic reconstruction, though these were not quantified in the cohort. All patients were followed for a median of 32 months, allowing capture of early and intermediate‑term outcomes. (Source: PubMed / Europe PMC) Key Takeaways for Patients Fibular tumor surgery can preserve the limb in most cases, but the risk of local recurrence is significant (about 1 in 2). Preserving the common peroneal nerve is possible in roughly two‑thirds of surgeries, reducing the chance of foot drop. Overall survival drops sharply after the second year; close surveillance with imaging is essential. Complications such as infection, nerve injury, and joint instability can affect recovery and may need additional procedures. Multidisciplinary care—combining surgery with chemotherapy, radiotherapy, and rehabilitation—offers the best chance of long‑term control. Questions to ask your surgeon: What surgical approach do you recommend and why? Will my common peroneal nerve be preserved, and what are the functional implications if it is not? What reconstruction options are available after segmental resection? How often will I need imaging follow‑up, and for how many years? What rehabilitation program will I follow to restore knee and ankle stability? Frequently Asked Questions What symptoms indicate a fibular tumor? Typical early signs are painless swelling or a palpable lump on the outer side of the leg; later, pain, bruising, or a pathologic fracture may develop. Is amputation ever necessary for a fibular tumor? Amputation is reserved for large, aggressive cancers that cannot be fully removed with limb‑sparing surgery or when vital structures are involved. How long does recovery take after a proximal fibulectomy? Most patients stay in the hospital 3–5 days, begin gentle range‑of‑motion exercises within the first week, and achieve full weight‑bearing by 8–12 weeks. Can the common peroneal nerve be reconstructed if it is damaged? Yes; nerve grafts or tendon transfer procedures can restore foot dorsiflexion, but results vary and rehabilitation is lengthy. Will I need chemotherapy after surgery? High‑grade sarcomas such as osteosarcoma and Ewing sarcoma typically require adjuvant chemotherapy, often before (neoadjuvant) and after (adjuvant) surgery.
