Introduction and Aims: Polyethylene wear continues to be the most significant issue following total hip arthroplasty (THA), leading to the current increase in use of alternative bearing surfaces. We performed a prospective, randomised, blinded clinical trial comparing

One hundred fifty one total hip arthroplasty (THA) with metal on metal hip system of without cement were followed at a mean of 5. 5 years (range 2. 6 years to 7 years). Original diseases were 134 hip in 123 cases with osteoarthritis and 17 hips in 13 with rheumatoid arthritis. The average Harris hip score of before the operation was 45. 3 points and at the follow-up time the average score was 88. 5 points. Radiographic findings in the incidence of partial radiolucent line around the component: in the acetabular component, no radiolucent line was observed, in the femoral component, marginal lucent lines were 8. 6% (13 hips). Cortical hypertrophy was observed in high ratio of 27. 2%(41 hips). There was no loosening and tilt of component over 5 degrees observed in any patient. Postoperative dislocation of the hip was observed 9 hips (6. 0%). Cobalt concentrations and chromium concentration in the serum were measured in cases in

Fracture of the acetabulum can lead to degenerative arthritis of the hip, avascular necrosis of the femoral head, or both. Total hip arthroplasty is a common form of surgical treatment when significant joint changes and pain are present. Ten patients with fracture acetabulum were treated in this study using

Background:
Patients with DDH are known to be at risk of early degenerative changes to their hips. To date, no consensus exists as to the most appropriate management of this group, with many surgical options being associated with specific complications such as dislocation and early wear. In addition, modern resurfacing methods are considered by many to be contra-indicated in patients with DDH due to the technical difficulty of the procedure. This prospective study analyses a single surgeon series of known DDH hips that underwent
