Adductor Myocutaneous Flap Coverage for Hip and Pelvic Disarticulations of Sarcomas with Buttock Contamination
Hip disarticulation and hemipelvectomy are alternatives to limb-salvage procedures for patients with extensive tumors of the upper thigh and buttocks. In cases when neither the conventional posterior gluteus maximus flap nor the anterior quadriceps flap can be used because of the location of the tumor, a medial adductor myocutaneous flap may be an alternative.
Curettage and Cryosurgery for Low-grade Cartilage Tumors Is Associated with Low Recurrence and High Function
Chondrosarcomas of bone traditionally have been treated by wide or radical excision, procedures that may result in considerable lifelong disability. Grade 1 chondrosarcomas have little or no metastatic potential and are often difficult to distinguish from painful benign enchondromas. Curettage with adjuvant cryosurgery has been proposed as an alternative therapy for Grade 1 chondrosarcomas given the generally better function after the procedure. However, because it is an intralesional procedure, curettage and cryosurgery may be associated with higher rates of recurrence.
Patients with malignant fibrous histiocytoma of bone (MFH-B) and osteosarcoma reportedly have comparable survival rates, despite the lesser chemosensitivity of patients with MFH-B compared with those with osteosarcoma.
Office-based Core Needle Biopsy of Bone and Soft Tissue Malignancies: An Accurate Alternative to Open Biopsy with Infrequent Complications
Biopsy is a critical step in the diagnosis of musculoskeletal malignancy. As an alternative to open biopsy, percutaneous core needle biopsy techniques have been developed. As many studies combine office-based, image-guided, and operative biopsies, the accuracy of office-based core needle biopsy is not well documented.
Solitary bone cysts (SBC), nonossifying fibromas (NOF), and fibrous dysplasia (FD) create benign intramedullary lytic bone lesions. They are typically asymptomatic and treated conservatively. We present a series of lesions that caused performance-limiting pain in young athletes, a symptom phenomenon and possible treatment indication that has been poorly described in the literature.
Multiplanar Osteotomy with Limited Wide Margins: A Tissue Preserving Surgical Technique for High-grade Bone Sarcomas
Limb-salvage surgery has been used during the last several decades to treat patients with high-grade bone sarcomas. In the short- and intermediate-term these surgeries have been associated with relatively good function and low revision rates. However, long-term studies show a high rate of soft tissue, implant, and bone-related complications. Multiplanar osteotomy with limited wide margins uses angled bone cuts to resect bone tumors with the goal of complete tumor removal while sparing host tissue although its impact on local recurrence is not known.
Extraarticular Knee Resection for Sarcomas with Preservation of the Extensor Mechanism: Surgical Technique and Review of Cases
Sarcomas in or contaminating the knee are rare but extremely challenging to treat. Complete resection of the joint is necessary, and often the entire extensor mechanism is removed as well. Reconstruction of the knee is challenging, and the resulting function may be compromised.
Image-guided needle biopsies are commonly used to diagnose musculoskeletal tumors, but nondiagnostic (ND) results can delay diagnosis and treatment. It is important to understand which factors or diagnoses predispose to a ND result so that appropriate patient education or a possible change in the clinical plan can be made. Currently it is unclear which factors or specific lesions are more likely to lead to a ND result after image-guided needle biopsy.
