Treatment of grade III osteonecrosis of the femoral head with a Charnley/Bicentric hemiarthroplasty.
Thirty-eight hips with Charnley/Bicentric hemiarthroplasties were reviewed. Preoperatively all hips had a Grade III osteonecrosis (Arlet & Ficat) of the femoral head. Follow-up ranged from 42 to 72 months with a mean of 56 months. ⋯ The mean total movement from full abduction to full adduction at the cup-acetabular articulation was 21 degrees, compared to 14 degrees at the inner component articulation. The results of cemented femoral components are predictably unfavourable in this young age group. However, the double articulation of the bipolar cup offers an acceptable method of treatment for this grade of osteonecrosis in the medium term.

Comparative StudyPyloromyotomy: why make an easy operation difficult?
Recently Ohri et al. advocated a modification to the standard pyloromyotomy for pyloric stenosis which they believed reduced postoperative vomiting. Their study had no control group to support their contention. ⋯ Data were recorded prospectively and the postoperative vomiting was assessed using the same scale as in the previous report. The incidence of vomiting was significantly less in the children undergoing the conventional operation (P = 0.03), suggesting that there is no justification for performing a double V-shaped pyloric incision in pyloric stenosis.
