To combat loosening caused by polyethylene wear debris, hip manufacturers developed improved and novel materials for the acetabular liners.
The edge of the acetabulum is surrounded by the "acetabular labrum", a fibrous structure that envelops the femoral head.
Impingement occurs when the femoral head rubs abnormally or its lacks a full range of motion in the acetabular socket.
He had surgery to repair a torn acetabular labrum and missed the remainder of the 2013 season.
It is widely used for femoral fractures, low back pain, acetabular fractures and hip fractures.
The best studied acetabular activity is that of octopus.
Stability was improved, but acetabular wear and subsequent failure rates were increased with these designs.
The acetabular notch is narrow or closed and on the femoral head the fovea is absent.
