解剖锁定钛板及桡侧阻挡钛板治疗桡骨远端C型骨折的疗效

Efficacy of anatomic locking titanium plate and radial blocking titanium plate in the treatment of distal radius type-C fracture

目的探讨解剖锁定钛板及桡侧阻挡钛板治疗桡骨远端C型骨折的疗效。方法将40例桡骨远端C型骨折患者按照治疗方法不同分为观察组(采用解剖锁定钛板及桡侧阻挡钛板治疗,20例)和对照组(采用单纯桡骨远端解剖锁定钛板治疗,20例)。记录两组术中骨折复位情况、术中出血量、手术时间、骨折愈合情况、掌倾角、尺偏角及腕关节活动度。结果患者均获得随访,时间2.5~6个月。术中观察组骨折断端均固定良好,对位对线满意,无桡侧骨块移位;对照组9例骨折复位及固定满意,11例存在不同程度的桡侧骨块移位。术中出血量、手术时间两组比较差异均无统计学意义(P>0.05)。两组骨折均愈合,时间10~12周。末次随访时,两组掌倾角比较差异无统计学意义(P>0.05);尺偏角及腕关节掌屈、背伸活动度观察组均大于对照组(P<0.05)。结论解剖锁定钛板及桡侧阻挡钛板治疗桡骨远端C型骨折,术中骨折复位简单,同时能有效减少桡侧骨块移位,更利于患者腕关节功能恢复。

Objective To investigate the effect of anatomic locking titanium plate and radial blocking plate for treatment of distal radius type-C fracture.Methods According to different treatment methods,40 patients with distal radius type-C fractures were divided into observation group(treated with anatomic locking titanium plate and radial blocking titanium plate,20 cases)and control group(treated with simple distal radius anatomic locking titanium plate,20 cases).The intraoperative reduction condition,intraoperative blood loss,operation time,fracture healing,palmar inclination,ulnar deviation and wrist motion were recorded.Results All patients were followed up for 2.5~6 months.During the operation,in the observation group,the broken ends of the fractures were fixed well,there were satisfactory alignment,without displacement of radial bone mass;and in the control group,9 cases had satisfactory fracture reduction and fixation,and 11 cases had different degree of displacement of radial bone mass.There were no statistical differences in the intraoperative blood loss volume and operation time between the two groups(P>0.05).The fractures of both groups healed within 10~12 weeks.At the last follow-up,there was no statistical difference in palmar inclination between the two groups(P>0.05),but the ulnar declination,carpal flexion and dorsal extension activity in the observation group were larger than those in the control group(P<0.05).Conclusions Anatomical locking titanium plate and radial blocking titanium plate in the treatment of distal radius type-C fracture are simply operated in fracture reduction during the surgery,and which can effectively reduce the displacement of radial bone mass,and are more conducive to the recovery of wrist joint function.
