2种内固定方法治疗C3桡骨远端骨折的疗效比较

Internal Fixation for C3 Distal Radial Fractures:Comparison of Two Methods

目的比较分析2种内固定方法治疗C3桡骨远端骨折的疗效。方法将48例C3桡骨远端骨折患者按随机数字表法分为2组,每组24例。观察组采用外固架固定治疗,对照组采用切开复位"T"型钢板内固定治疗。对2组患者手术时间、术中出血量、术后骨折愈合时间及腕关节功能的恢复情况进行比较。结果观察组手术时间短于对照组、术中出血量少于对照组[(42.5±6.2)min、(53.0±10.5)mL比(75.6±9.1)min、(139.2±13.5)mL,均P<0.05];2组术后骨折愈合时间比较差异无统计学意义(P>0.05)。2组患者均随访1年,根据Gartland-Werley腕关节功能评分标准,观察组优良率为91.7%,对照组优良率为95.8%,2组比较差异无统计学意义(χ2=1.058,P>0.05)。结论外固定支架具有安装简单、创伤小、手术时间短及出血量少等特点,在桡骨远端不稳定骨折的治疗中有很大空间。

Objective To compare the clinical efficacies of two internal fixation methods for C3 distal radius fractures.Methods Forty-eight patients with C3 distal radius fractures were ran-domly divided into two groups,with 24 patients in each group.The observation group was treated with external fixation.The control group was given open reduction and internal fixation with T-plate.The operation time,intraoperative blood loss,postoperative fracture healing time and wrist joint function were compared between the two groups.Results Compared with control group,ex-ternal fixation significantly shortened operation time((42.5±6.2)min vs(75.6 ±9.1)min,P <0.05),and obviously reduced intraoperative blood loss((53.0±10.5)mL vs (139.2±13.5)mL, P <0.05).The difference in postoperative fracture healing time was not significant between the two groups (P >0.05).According to the Gartland-Werley criteria,no significant difference in the excellent rate of wrist joint function was found between observation group and control group after 1 year of follow-up (91.7% vs 95.8%,χ2 =1.058,P >0.05).Conclusion The external fixator is associated with simple installation,minimal trauma,short operation time and mild bleeding in the treatment of unstable distal radius fractures.
