PURPOSE To improve function after pelvic resection involving the acetabulum, using an anatomic composite implant built with screws and cement. MATERIAL AND METHOD Since 1990, 66 patients with peri-acetabular bone malignancies have been treated by extensive resection followed by hand-modelled innominate prosthesis with partially constrained total hip prosthesis. The hand-modelled innominate pr...

PURPOSE The AMS700 Ultrex penile prosthesis is an example of the design changes that penile prostheses have undergone to improve mechanical reliability. Few studies have reviewed an overall experience with the AMS700 Ultrex prosthesis. We review patient outcomes, surgical complications, and Ultrex cylinder intermediate term mechanical reliability and function. MATERIALS AND METHODS Between Ma...

Chondrosarcoma is a malignant cartilage-forming neoplasm. It is difficult to treat because of resistance to both chemotherapy and radiation, making wide local excision the only treatment. This report presents an active, 43 year-old man who was diagnosed with recurrent clear cell chondrosarcoma of the proximal left femur, previously reconstructed with a total hip prosthesis, extending to the wei...

Ischemic priapism is a urological emergency that has been associated with long-standing and irreversible adverse effects on erectile function. Studies have demonstrated a linear relationship between the duration of critically ischemic episodes and the subsequent development of corporal fibrosis and irreversible erectile function loss. Placement of a penile prosthesis is a well-established thera...

Background:  The purpose of this study was to report the preoperative complaints and postoperative outcome of patients after removal of the radial head prosthesis.   Methods:  This is a retrospective review of 14 adult patients (6 females and 8 males) from 2007 to 2011, who underwent radial head prosthesis removal by three surgeons. The average time between implantation and removal was 23 month...

BACKGROUND AND PURPOSE There have been numerous reports of animal models of osteomyelitis. Very few of these have been prosthesis models that imitate human conditions. We have developed a new rat model of implant-related osteomyelitis that mimics human osteomyelitis, to investigate the pathology of infection after orthopedic implant surgery. METHODS 2 wild-type strains of Staphylococcus aureu...
