Objective : To evaluate the efficiency of intermaxillary traction by the use of titanium screw implantation for the treatment of jaw fracture .

目的：探讨应用牵引 钉行颌间 牵引术治疗颌骨骨折后牙关系紊乱的效果。

74.5 % of the patients treated with external fixation support 57.1 % of calcaneal traction combined with plaster cast fixation group and 56.2 % of plate screw internal fixation after open reduction obtained excellent and good results .

其优良率为：应用外固定支架治疗为745%，跟骨 牵引石膏外固定治疗为571%，切开复位钢板 螺钉内固定治疗为562%。

Cases treated by skull traction lost their anatomic reduction . Of the 21 cases treated by the pedicle screw fixation 2 had loosened internal fixation but 19 experienced no screw loosening and their fractures were cured entirely without limited function of the cervical vertebra .

15例颅骨 牵引者6例丢失复位位置，21例椎弓根 螺钉内固定术者2例内固定松动，余均获骨性愈合，无颈椎功能受限。

Methods Twenty four cases of patients with dislocation of the hip and fracture of femur head were treated by skeletal traction open reduction and fixation with absorbable screw and absorbable stick or total hip replacement respectively .

方法本组对24例股骨头骨折采用骨 牵引治疗、切开复位可吸收 螺丝 钉结合可吸收棒固定、全髋置换术治疗。

Fifteen patients were treated by bone traction 32 patients by fixation with several broken caudal screws and 47 patients by internal fixation with the dynamic hip screw ( DHS ) respectively .

采用骨 牵引15例，多枚折尾钉固定32例，动力髋 螺钉内固定47例。
