Background: Limb salvaging surgeries are current surgical treatment of extremity bone sarcomas. Resected bonereplacement consists of two main methods; tumor prosthesis versus structural allograft. Biological reconstruction withan allograft is an economic cheap method in young sarcoma patients, however, the surgeons are more convinced withtumor prosthesis replacement.Methods: We evaluated the sh...

AbstractIntroduction Silicone gel breast implants are used for breast reconstruction post mastectomy. In the event of cancer recurrence, the radiation oncologists are forced to irradiate through the prosthesis device. Due to prosthesis higher atomic number dose perturbations occur during treatment. This study determined the influence of silicone gel thickness on the photon beam distribution. Ma...

The Ilizarov fixator can be used as a bone regenerator to correct limb-length discrepancies in patients who require limb lengthening.A 17-year-old man presented with 12 cm of left lower-limb shortening and amputation at the left mid-forefoot region, which was the result of severe burns of the left lower limb at 2 years of age. The burns damaged the distal femoral, proximal, and distal tibial ph...

Background: The aim of this study is to adapt the two most common grading systems of surgical complications; the Satava system for perioperative complications, and the modified Clavien grading system for the postoperative complications on the surgical complications of penile prosthesis surgery. Methods and Findings: Between Oct 1990 and Dec 2011, 422 patients were treated with penile prosthesis...

Surgical procedures, especially total laryngectomy, used for treatment of advanced laryngeal carcinoma, have a profound adverse effect on the patient's physical, functional, and emotional health, and almost always decrease quality of life. There are three main types of voice rehabilitation after surgery. They are: esophageal speech techniques, the use of artificial larynx devices and tracheoeso...

A primary objective in developing a neural prosthesis is to replace neural circuitry in the brain that no longer functions appropriately. Such a goal requires artificial reconstruction of neuron-to-neuron connections in a way that can be recognized by the remaining normal circuitry, and that promotes appropriate interaction. In this study, the application of a specially designed neural prosthes...

The hip joint is a strongly loaded joint and highly vulnerable to any diseases and pathological changes related to loading conditions (Wall, 2002). Improper load distribution in the hip joint leads to its pathological changes that consist in anomalous growth of the acetabulum and femur. In the most drastic clinical cases the only way of treatment is to replace the natural degenerated joint with...

OBJECTIVE Developing functional artificial limbs for amputees has been a centuries-old challenge in medicine. We review the mechanical and neurologic principles of "cineplastic operations" and "plastic motors" used to restore movements in prostheses, with special attention to the work of Giuliano Vanghetti. METHODS We evaluated original publications describing cineplastic operations, biograph...

' Executive Director, Committee on Prosthetics Research and Development, National Research Council, 2101 Constitution Ave., N. W., Washington, D.C. 20418. The concept of constructing a belowknee prosthesis with side joints and a thigh lacer was set forth by the Dutch surgeon Verduin in 1696 (Fig. 1) and followed universally until the advent of the patellar-tendon-bearing prosthesis in the late ...

This article describes a novel approach using high-dose neoadjuvant chemotherapy with wide tissue resection and a specially designed artificial joint in 104 patients with stage IIB osteosarcoma near the knee. Sixty-four lesions were located at the distal femur, 39 at the proximal tibia, and 1 invaded the proximal tibia from the distal femur. Pathological fracture was present in 9 patients. Thre...
