ABSTRACT

Objective To establish clinical diagnostic criteria for zero-stage non-traumatic osteonecrosis of femoral head,and then to check the accuracy and value of the criteria in clinical application through combined intervention therapy including the administration of traditional Chinese medicine and physical therapy.Methods The clinical data of 258 patients suffering from non-traumatic osteonecrosis of femoral head were retrospectively analyzed.Clinical diagnostic criteria for zero-stage non-traumatic osteonecrosis of femoral head were established based on the analysis.Then a clinical comparative study concerning the criteria was performed,so as to verify its authority.Results The established criteria were proved to be satisfactory.The sensitivity,specificity and accuracy of the criteria were 93.7%,86.4% and 89.7%,respectively.The clinical comparative study showed that the prevalence of non-traumatic osteonecrosis of femoral head in the intervention group(34.2%)was obviously lower than that of the non-intervention group(84.9%,P
