[Progress of joint-preserving procedures for treatment of avascular necrosis of femoral head].
OBJECTIVE
To review the researches on the joint-preserving procedures for the treatment of the avascular necrosis (AVN) of the femoral head.


METHODS
The latest original literatures about the joint-preserving procedures for the treatment of AVN of the femoral head were extensively reviewed.


RESULTS
There were many surgical joint-preserving procedures to treat AVN of the femoral head, such as core decompression, bone grafting, and osteotomy. Most researchers achieved excellent clinical results by using the joint-preserving procedures to treat the early stages of AVN of the femoral head.


CONCLUSIONS
Treating AVN of the femoral head by the joint-preserving procedures, especially the free vascularized fibula grafting, can achieve an excellent long-term clinical outcome.
