Nontraumatic osteonecrosis of the femoral head / 中国矫形外科杂志

ABSTRACT

In this review,concepts concerning etiology and nonoperative and operative treatment methods have been analyzed.This article is based almost exclusively on peer-reviewed studies.The etiology of nontraumatic osteonecrosis of the femoral head may have genetic basis.The interaction between certain risk factors and a genetic predisposition may determine whether this disease will develop in a particular individual.Early diagnosis and intervention prior to collapse of the femoral head is key to a successful outcome of joint-preserving procedures.The rational for use of joint-sparing procedure in the treatment of this disease is based on radiographic measurements and findings with other imaging modalities.The results of joint-preserving procedures are less satisfactory than the results of total hip arthroplasty for femoral head than have already collapsed.New pharmacological measures as well as the use of growth and differentiation factors for the prevention and treatment of this disease may eventually alter our treatment approach,but it is necessary to await results of clinical research with long-term follow-up of these patients.
