Femoral head necrosis

Joint-preserving surgery in cases of femoral head necrosis

In cases of femoral head necrosis, a joint-preserving operation aims to save the joint and reduce pressure on the dying femoral head. In doing so, blood flow will be restored to the bone. In terms of femoral head necrosis surgical methods like intertrochanteric flexion osteotomy or drilling of the femoral head are  proven effective in early stages (Diehl et al 2005).This type of surgery is usually only successful during the early stages of the disease. During what is called a transposition osteotomy, the affected bone is removed from the area of excessive force so that overall pressure on the hip is reduced.
