Abstract
Total hip replacement has become a widely accepted procedure in severely affected hip joints. However, it is unknown how long an artificial joint will hold its function and there is no guarantee of absence of complications for a longer period of time.
From the standpoint of these problems, we performed the total replacement of the hip in young adult patients and middle aged patients which consisted of an acetabular socket and a cup of concentric type.
Nineteen hips were treated with the replacement. Eighteen hips which have been completed over 6 months were evaluated in relation to pain, range of motion and overall assessment. In the assessment of pain, 15 of 18 hips were graded as no pain or slight pain. Most patients gained adequate range of motion but the improvement was not quite as remarkable as relief of pain.
The replacement with the combined use of an acetabular socket and a metal cup can be performed on younger patients and middle aged patients and has advantages in comparison with the exceptional use of conventional replacement at such age. The better preservation of bone allows for further reconstruction procedures on the hip. The avoidance of cementing excludes unknown long term effects which might occur.
