Various modified instruments are used for the anterior reconstruction of the tumor lesion affecting the second cervical vertebra, but there have been no reports regarding individual integrated artificial axis (IAA) prosthesis fabricated by selective laser melting. In the present work, a new type of IAA prosthesis has been designed with a 3-dimensional (3D) finite element model of normal occiput...

PURPOSE To assess the clinical results of pelvic reconstruction using a saddle prosthesis following limb salvage operation for periacetabular tumour. METHODS 12 patients with sarcoma and 4 with metastasis involving the pelvis were treated using the saddle prosthesis between 1995 and 2003 inclusive. Wide pelvic resection was performed for all patients with sarcoma and one with a metastatic les...

It is generally accepted that the development of erectile dysfunction is frequently attributed to both psychogenic factors as well as physiological alterations in neural, vascular, hormonal and endothelial function. Despite the advent of oral and intracavernosal erectile drugs, penile prosthesis implant remains a relevant and desired treatment option as many men became refractory to medical the...

We report our early experience with a new peri-acetabular reconstruction endoprosthesis used for pelvic reconstruction after tumour resection. The outcome of 21 patients who underwent limb salvage following type II pelvic resection and reconstruction using the peri-acetabular reconstruction prosthesis between 2000 and 2006 was retrospectively reviewed. This prosthesis was designed to use the re...

Between 1997 and 2007, 68 consecutive patients underwent replacement of the proximal humerus for tumour using a fixed-fulcrum massive endoprosthesis. Their mean age was 46 years (7 to 87). Ten patients were lost to follow-up and 16 patients died. The 42 surviving patients were assessed using the Musculoskeletal Tumor Society (MSTS) Score and the Toronto Extremity Salvage Score (TESS) at a mean ...

BACKGROUND Patients undergoing proximal femoral replacement for tumor resection often have compromised hip abductor muscles resulting in a Trendelenberg limp and hip instability. Commercially available proximal femoral prostheses offer several designs with varying sites of attachment for the abductor muscles, however, no analyses of these configurations have been performed to determine which de...

M yocardial infarction secondary to coronary embolization is infrequently encountered. Approximately 100 cases have l)een reported with the majority being associated with bacterial endocarditis or syphilis.’ Other causes are paradoxic embolization from atrial or ventricular mural thrombi, avulsed tissue or tumor2 and mitral stenosis with atrial fibrillation. a Coronary embolization has also bee...

The proximal tibia is a difficult area in which to perform a wide resection of a bone tumor. This difficulty is due to the intimate relationship of tumor in this location to the nerves and blood vessels of the leg, inadequate soft tissue coverage after endoprosthetic reconstruction, and the need to reconstruct the extensor mechanism. Competence of the extensor mechanism is the major determinant...
