Rotational acetabular osteotomy provides excellent congruity at the site of the osteotomy and good coverage of the femoral head. However, necrosis of the transferred acetabulum has been reported after this procedure. The purpose of this study was to evaluate the effects of rotational acetabular osteotomy on the blood flow rate of the osteotomized acetabulum.
Eleven hips of ten adult mongrel dogs were utilized. Blood flow rate was determined using the hydrogen washout technique. The platinum electrode was inserted into the acetabulum after minimum dissection. Then, the blood flow rate of the acetabulum was measured after each of the following procedures; intact; stripping off the gluteal muscles from the acetabulum; circumacetabular osteotomy.
The blood flow rate of the acetabulum was significantly decreased from the control value after stripping of the gluteal muscles from the acetabulum. The addition of circumacetabular osteotomy caused a complete arrest of blood flow in the acetabulum.
These results indicate that the acetabulum receives blood flow from the gluteal muscles and the bone marrow in an animal model. Hip joint capsule does not seem to have any role in supplying the nutritional pathways to the acetabulum.
