Infected Prostheses after Lower-Extremity Bone Tumor Resection: Clinical Outcomes of 100 Patients.

Background: Infection of megaprostheses after bone tumor resection is a major concern; management is challenging. This study evaluated the survivability from such infections, the microbial isolates, treatment tactics, and outcome of megaprosthesis reconstructions.

Materials And Methods: We studied 1,161 patients retrospectively who underwent megaprosthesis reconstruction for limb salvage after a sarcoma from 1983 to 2010.

Infection after surgical resection for pelvic bone tumors: an analysis of 270 patients from one institution.

Background: Surgical treatment of pelvic tumors with or without acetabular involvement is challenging. Primary goals of surgery include local control and maintenance of good quality of life, but the procedures are marked by significant perioperative morbidity and complications.

Questions/purposes: We wished to (1) evaluate the frequency of infection after limb salvage surgical resection for bone tumors in the pelvis; (2) determine whether infection after these resections is associated with particular risk factors, including pelvic reconstruction, radiotherapy or chemotherapy, type of resection, and age; and (3) analyze treatment of these infections, particularly with respect to the need of additional surgery or hemipelvectomy.

Survival analysis of patients with chondrosarcomas of the pelvis.

Background: Studies for patients with pelvic chondrosarcomas are limited. This study determines the outcome of patients with pelvic chondrosarcomas, and whether there is any association with tumors' grade, type, stage, margins and pelvic location.

Materials And Methods: We retrospectively studied 215 patients with pelvic chondrosarcomas.

Post-tsunami primary Scedosporium apiospermum osteomyelitis of the knee in an immunocompetent patient.

Scedosporium apiospermum is a filamentous fungus present in soil and polluted waters that may cause infection by direct inoculation. Osteomyelitis represents a challenge both for diagnosis and treatment. We report a case of post-tsunami primary S.

Hibernomas: clinicopathological features, diagnosis, and treatment of 17 cases.

Hibernomas are rare benign adipose tumors composed of brown fat cells with granular, multivacuolated cytoplasm admixed with white adipose tissue. They account for 1.6% of benign lipomatous tumors and approximately 1.
