The significance of collapse prediction in clinical assessment of the femoral head necrosis
摘要
Abstract
Objective To evaluate the significance of collapse prediction in clinical assessment of femoral head necrosis. Methods Osteonecrosis of femoral head ( ONFH ) in 37 hips of 30 patients, who received no systemic treatment of ONFH, were assessed with several major collapse prediction methods. Results Prediction accuracy rates of collapse with Modified Kerboul method. necrotic zone projective surface area ratio and necrotic zone volume ratio were 62. 2％ , 56. 8％ and 83. 8％ , respectively; while Youden's indexes were 0. 17 , 0. 045 , 0. 655 , respectively. In the anteroposterior typing, no type B collapse was revealed; while type C1 and C2 prediction accuracy was 44. 4％ and 94. 4％ ,respectively, with Youden's indexes of 0 and 0. 9. Conclusion Conservative treatment can be applied in patients with type B or central necrosis, which suggests low collapse risk; while surgical treatment should be applied in type C2 necrosis, which suggests high risk of collapse is high. However, surgical treatment is considered in type C1 necrosis with necrosis volume percentage over 40％ . Each prediction method has its advantages and disadvantages and can not used alone.Comprehensive analysis should base on orthotopic typing for decision. Early diagnosis is crucial for improvement of the efficacy of Chinese medicine on hip preserviation.关键词
