防止小儿骨纤维异样增殖症复发措施的探讨

Prevention of Recurrence of Osteofibrous Dysplasia in children

目的:对小儿长骨纤维异样增殖症的复发原因及手术治疗进行分析总结,对防止术后复发的措施进行探讨。临床资料:收治小儿长骨纤维异样增殖症44例,均经病理证实。该病术后复发率颇高,12例因复发而再次或多次手术,复发率达36%。其中胫骨为最常见的复发部位,占67%。结果:35例行刮除病灶植骨术,术后11例复发。其中胫骨13例,复发7例。对9例胫骨以前方破坏为主的病变,手术方法由刮除病灶植骨术改进为蝶形切除病灶植骨术,术后1例复发。结论:蝶形切除病灶植骨术是防止小儿骨纤维异样增殖症术后复发的较好方法。

Objective:To analyse and summarize the diagnosis,recurrence and operative treatment for the long-bone osteofibrous Dysplasia in children.Methods:Forty-four cases of long bone osteofibrous dysplasia were reviewed with a recurrent rate of 36%.The common site was tibia(67%).Results:Thirty-five cases underwent limited curettage and bone grafts with 11 re- lapse after operation(tibia 7).In order to reduce the recurrence,9 were treated by extensive re- section and bone grtaf in stead of limited curettage,only one relapsed.Conclusions:The extensive resection with bone grafts is a better method to prevent the recurrence of the long bone osteofi- brous dysplasia in children.
