title: [Progress of joint-preserving procedures for treatment of avascular necrosis of femoral head].
abstract: 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.
