Functional graded materials (FGMs) are widely used for hip plant component because of their specific properties in a design to meet the requirements joint system. Stem is manufactured with concept making new FGM using three different composition Ti, CrCo, and HA. This has led development suitable functional femoral parts that can be long time. The helped reduce protection stress associated exis...

Several investigators have pointed out that electron and neutron contamination from high-energy photon beams are clinically important. The aim of this study is to assess electron and neutron contamination production by various prostheses in a high-energy photon beam of a medical linac. A 15 MV Siemens PRIMUS linac was simulated by MCNPX Monte Carlo (MC) code and the results of percentage depth ...

Infection remains a serious complication after total hip arthroplasty (THA) and is a leading cause of hip revision surgery. It is currently accepted that removal of the prosthesis is essential to curing an infection when facing chronic PJIs with prosthesis loosening. In order to avoid the disadvantages of a two-stage approach, some authors have proposed a one-stage hip revision for the treatmen...

PURPOSE To assess the clinical and radiological outcomes of total hip replacement (THR) using the cone femoral prosthesis. METHODS Four men and 15 women (26 hips) aged 19 to 78 (mean, 45) years underwent THR for osteoarthritis of the hip with femoral dysplasia using the cone femoral prosthesis. Only 17 patients (24 hips) were available for review. Pain and functional limitation were assessed ...

The study involved a 82 years old patient, who was operated 15 years ago for coxarthrosis of the left hip. He underwent placement of total hip prosthesis with good clinical and radiological evolution. Then, 10 years ago, he was operated on the right side, undergoing placement of total hip prosthesis. The evolution on right side was marked by hip pain and a total loss of function of the left low...

INTRODUCTION Many papers have been published recently on the subject of pseudotumors surrounding metal-on-metal hip resurfacing and replacement prostheses. These pseudotumors are sterile, inflammatory lesions within the periprosthetic tissues and have been variously termed masses, cysts, bursae, collections, or aseptic lymphocyte-dominated vasculitis-associated lesions (ALVAL). The prevalence o...

Introduction Cystic echinococcosis of the bone is rare and difficult to treat due to frequent recurrences, especially in certain locations such as ilium and hip, where radical surgery is difficult to achieve. Case Report We present a case of a 35-year-old female of the Indian subcontinent who had complaints of pain in left hip and limp since 1 year. The first clinical and radiological diagnos...
