Treatment of giant cell tumor of bone (GCT) often is complicated by local recurrence. Intralesional curettage is the standard of care for primary GCTs. However, there is controversy whether intralesional curettage should be preferred over wide resection in recurrent GCTs.
Many surgeons treat giant cell tumor of bone (GCT) with intralesional curettage. Wide resection is reserved for extensive bone destruction where joint preservation is impossible or when expendable sites (eg, fibular head) are affected. Adjuvants such as polymethylmethacrylate and phenol have been recommended to reduce the risk of local recurrence after intralesional surgery. However, the best treatment of these tumors and risk factors for recurrence remain controversial.
Vascular reconstruction in infants constitutes a surgical challenge and is indicated frequently for acute occlusions. With the presence of a subacute vascular occlusion, including that produced by tumor resection, collateral circulation develops quickly. Thus a surgeon can consider tumor and vessel resection, without the need for vascular reconstruction.
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.
