Does Limb-salvage Surgery Offer Patients Better Quality of Life and Functional Capacity than Amputation?
Patients with aggressive lower extremity musculoskeletal tumors may be candidates for either above-knee amputation or limb-salvage surgery. However, the subjective and objective benefits of limb-salvage surgery compared with amputation are not fully clear.
A novel calcium sulfate–calcium phosphate composite injectable bone graft substitute has been approved by the FDA for filling bone defects in a nonweightbearing application based on preclinical studies. Its utility has not been documented in the literature.
Similar Survival but Better Function for Patients after Limb Salvage versus Amputation for Distal Tibia Osteosarcoma
Amputation has been the standard surgical treatment for distal tibia osteosarcoma. Advances in surgery and chemotherapy have made limb salvage possible. However, it is unclear whether limb salvage offers any improvement in function without compromising survival.
De novo malignancies are serious complications in the late postoperative period after liver transplantation. The most common de novo tumors are skin malignancies, posttransplantation lymphoproliferative disorder, tumors of the head and neck, and Kaposi’s sarcoma. Such posttransplant de novo malignancies are apparently rarely found in bone.
Physeal distraction facilitates metaphyseal bone tumor resection in children and preserves the adjacent joint. The technique was first described by Cañadell. Tumor resection procedures allowing limb-sparing reconstruction have been used increasingly in recent years without compromising oncologic principles.
Sacrectomy may offer curative potential for primary sarcomas of the sacrum. However, it is unclear whether and to what extent sacrectomies achieve local control.
It is commonly assumed patients with high-grade soft tissue sarcomas who are diagnosed and treated quickly after the first onset of symptoms fare better than those with longer symptoms before treatment. The literature contains no substantive data to support this assumption for soft tissue sarcomas, particularly for high-grade lesions.
Intralesional Excision versus Wide Resection for Giant Cell Tumor Involving the Acetabulum: Which is Better?
Because of the anatomic complexity of the pelvis, there is no standard surgical treatment for giant cell tumors (GCTs) of the pelvic bones, especially in the periacetabular region. Treatment options include intralesional curettage with or without adjunctive techniques and wide resection. The best surgical treatment of a pelvic GCT remains controversial.
What are Estimated Reimbursements for Lower Extremity Prostheses Capable of Surgical and Nonsurgical Lengthening?
Growing prostheses accommodate skeletally immature patients with bone tumors undergoing limb-preserving surgery. Early devices required surgical procedures for lengthening; recent devices lengthen without surgery. Expenses for newer expandable devices that lengthen without surgery are more than for their predecessors but overall reimbursement amounts are not known.
