Whether the acetabular gland secretions of penetrating cercariae could act as attractants was investigated in the gradient chamber.
The contents of free arginine, and also of total arginine after hydrolysis of the proteins, did not change significantly when the cercariae emptied their acetabular glands.
It has been suggested by some surgeons, however, that in doing this one runs the risk of implanting the components incorrectly, especially the acetabular component.
If the acetabular labrum requires repair, specially designed anchors may be used.
It consists of strong, flattened fibers, which cross the acetabular notch, and convert it into a foramen through which the nutrient vessels enter the joint.
The notch is converted into a foramen by the transverse acetabular ligament; through the foramen nutrient vessels and nerves enter the joint.
Mechanical risk factors include obesity, coxa profunda, femoral or acetabular retroversion.
The acetabular notch is narrow or closed and on the femoral head the fovea is absent.
