目的 为探讨骨骺突出指数对儿童股骨头缺血性坏死包容手术选择应用的实际价值。方法 对Salter和Chiari手术方法治疗的 4 5例CatterallⅢ、Ⅳ (SalterB)病例进行分析。结果 4 5例患儿正位X线片下测得其骨骺突出指数在 8%～ 2 0 %之间2 4例 ,2 2 %～ 5 3%之间 2 1例。术后结果以Mose法评定 ,Salter组 2 7例 ,优 12例 ,良 9例 ,差 6例 ;Chiari组 18例 ,其中优占 9例 ,良 6例 ,差 3例。Salter组差者 6例中骨骺突出指数均大于 2 0 %。结论 骨骺突出指数在骨盆包容手术方法选择及预后判定有重要参考价值。应把小于 2 0 %的骨骺突出指数纳入对Salter手术选择的重要参数指标 ;骨骺突出指数大于 2 0 %者宜选择Chiari手术
Objective To explore the practical value of epiphysis protrusion index in the selection and application of inclusive femoral head ischemic necrosis. Methods Forty-five cases of Catterall III and IV (SalterB) treated by Salter and Chiari surgical methods were analyzed. Results The index of epiphyseal protrusion in 45 children with orthopedic radiographs ranged from 24% to 20%, 21% to 52%. The postoperative results were evaluated by Mose method. There were 27 cases in Salter group, 12 cases were excellent, 9 cases good and 6 cases poor; 18 cases were Chiari group, 9 cases were excellent, 6 cases good and 3 cases poor. In the poor group of Salter, the prominent index of epiphyseal were all more than 20%. Conclusions The epiphyseal protrusion index has important reference value in the methods of pelvic inclusion surgery and prognosis. Less than 20% epiphyseal protrusion index should be included in the selection of Salter important parameters of indicators; epiphysis protrusion index greater than 20% should choose Chiari surgery
