Total Hip Replacement in Osteoarthrosis using the Charnley Prosthesis

Reconstruction of the Acetabulum in Developmental Dysplasia of the Hip in Total Hip Replacement

Developmental dysplasia of the hip (DDH) or congenital hip dysplasia (CDH) is the most prevalent developmental childhood hip disorder. It includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. The natural history of neglected DDH in adults is highly variable. The mean age of onset of symptoms is 34.5 years for dysplastic DD...

The principle of low frictional torque in the Charnley total hip replacement.

The design of the Charnley total hip replacement follows the principle of low frictional torque. It is based on the largest possible difference between the radius of the femoral head and that of the outer aspect of the acetabular component. The aim is to protect the bone-cement interface by movement taking place at the smaller radius, the articulation. This is achieved in clinical practice by a...

Total hip replacement using the McKee-Farrar prosthesis. In rheumatoid arthritis, Still's disease, and ankylosing spondylitis.

Severe destructive change in the hip joint is not infrequent in patients with long-standing rheumatoid arthritis and Still's disease. In ankylosing spondylitis, whether primary or secondary to other diseases such as Still's disease, there may be a bony fusion or destruction. Various types of hip arthroplasty have been carried out in the last 30 years (Smith-Petersen, 1939; Chamley, 1961). The e...

Comparison of Titanium vs. Polycel Total Ossicular Replacement Prosthesis

Introduction: Even though modern technology progresses so rapidly, annals of otology are replete with so many challenging article, which often compare various types of prosthesis. Since there has not been a prospective randomized clinical trial study which compares the hearing result of total ossicular replacement prosthesis made of Titanium with omega connector and Polycel in the literature, w...
