Surface damage to an Oxinium femoral head prosthesis after dislocation.
نویسندگان
چکیده
During open reduction of an irreducible anterior dislocation of a total hip replacement with an Oxinium femoral head, it was observed that the head had been significantly damaged. Gross and scanning electron microscopic examination revealed cracking, gouging, and delamination of the surface. Because of the risk which this poses for damaging the polyethylene acetabular liner, it is strongly recommended that patients with this type of prosthetic head be carefully monitored after a dislocation.

متن کاملDamage of an Oxinium femoral head and polyethylene liner following 'routine' total hip replacement.
We present a case of early retrieval of an Oxinium femoral head and corresponding polyethylene liner where there was significant surface damage to the head and polyethylene. The implants were retrieved at the time of revision surgery to correct leg-length discrepancy just 48 hours after the primary hip replacement. Appropriate analysis of the retrieved femoral head demonstrated loss of the Oxin...

This randomized study was performed to compare wear and migration of five different cemented total hip joint articulations in 150 patients. The patients received either a Charnley femoral stem with a 22.2 mm head or a Spectron EF femoral stem with a 28 mm head. The Charnley articulated with a γ-sterilized Charnley Ogee acetabular cup. The Spectron EF was used with either EtO-sterilized non-cros...

Traumatic anterior dislocation of the hip is an extremely rare condition in children and open dislocation is even rarer. Thisisusually caused by high-energy trauma. In the current study, we present a case of an eight-year-old child suffering froman open anterior–inferior dislocation of the right hip concomitant with pelvic ring disruption and an ipsilateral open distalfemoral fracture (Salter-H...
متن کاملEfficacy of alumina ceramic heads for cemented total hip arthroplasty.
Fifty-seven cemented total hip arthroplasties (THAs) were reviewed in cases of osteoarthrosis secondary to congenital dysplasia or dislocation. The bearing surface of the prosthesis used in this series consists of a polyethylene acetabular component on an alumina ceramic head. All acetabular components were positioned at the same level as the original acetabulum, and an autologous femoral head ...
