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.
There is no consensus as to which surgical approach to the treatment of giant cell tumor of bone is most appropriate or which patients are at a higher risk for recurrence or metastasis.
Sarcomas require a wide margin of resection including a cuff of normal tissue to minimize the risk of local recurrence. The amount of tissue that constitutes a wide margin is unclear in the literature.
Does Adjunctive Chemotherapy Reduce Remission Rates Compared to Cortisone Alone in Unifocal or Multifocal Histiocytosis of Bone?
Langerhans cell histiocytosis (LCH) is a rare disorder that can affect almost any organ, including bone. Treatment options include local corticosteroid infiltration in isolated bone lesions and oral corticosteroids and chemotherapy in multifocal bone lesions. Several studies show local corticosteroid injection in unifocal bone lesions heal in more than 75% of patients with minimal side effects. Therefore, it is unclear whether chemotherapy adds materially to the healing rate.
Failure of endoprosthetic reconstruction with conventional stems due to aseptic loosening remains a challenge for maintenance of limb integrity and function. The Compressimplant (Biomet Inc, Warsaw, IN, USA) attempts to avoid aseptic failure by means of a unique technologic innovation. Though the existing literature suggests survivorship of Compressand stemmed implants is similar in the short term, studies are limited by population size and followup duration.
Tumor enlargement after chemotherapy is considered one of the high-risk factors for local recurrence and survival in osteosarcoma. We hypothesized patients with this risk factor will have similar survival regardless of the development of local recurrence.
The Compress® device uses a unique design using compressive forces to achieve bone ingrowth on the prosthesis. Because of its design, removal of this device may require special techniques to preserve host bone.
