The Effect To The Femoral Head Epiphysis And Prognosis Analysis Of Weight Bearing After Surgical Containment Treatment Of Perthes Disease

Objective:To observe and analyze the variation of femoral head epiphysis in early weight bearing after surgical containment treatment of Perthes disease,and analyze the relation between classification and prognosis,in order to discuss the surgical containment treatment of Perthes disease.Methods: we collect the patients who accepted surgical containment treatment in pediatric department of orthopedics in Shanghai Jiao Tong University Affiliated Sixth People’s Hospital from 2010 to 2014.Count patients’ datas including age,gender,preoperative stage and classification(Catterall classification,Herring lateral pillar classification),the femoral head epiphysis index of preoperation and postoperation,the Stulberg classification of hip in the last time of follow up and use SPSS 19.0 to analyze and compare.Results:69patients(73hips)were included in this study.No statistical differences were shown between preoperation and postoperation in the affected femoral head epiphysis index,the affected femoral head epiphysis index shows a slight decrease trend from preoperation,6 months after operation to 12 months after operation.But this trend is mainly caused by femoral epiphysis width increase,the height of epiphysis showed no statistical difference between preoperation,6 months and 12 months after operation.Catterall classification and risk signs have no correlation with Stulberg classification after containment treatment,while Herring lateral pillar classification has correlation with Stulberg classification.Conclusion:This study showed that the affected femoral head would be further mild flat within 1 year after surgery.The width of the epiphysis increased,and the height remained unchanged.The result of the last follow up showed that the affected femoral head epiphysis had no significant further flat.Herring lateral pillar classification can be used in the prognosis of Perthes disease,the more affected of the lateral pillar,the worse of the prognosis will be.
