目的
2
探讨掌侧解剖锁定钢板结合背侧微型钢板治疗复杂桡骨远端骨折的临床疗效。
方法
2
回顾性分析我院2019年1月至2023年6月行掌侧锁定钢板结合背侧微型钢板治疗的复杂桡骨远端骨折。影像学分析关节面骨折块复位质量。随访记录患者Mayo腕关节功能评分、DASH评分、腕关节活动度、骨折愈合时间及并发症发生。
结果
2
共纳入28例患者,男19例、女9例,年龄(45.4±11.9)岁,随访时间(14.9±3.6)月,其中高处坠落伤11例,交通伤9例,摔伤8例。术后掌倾角5.1±4.9°,尺偏角19.8±2.8°;末次随访掌倾角5.2±4.8°、尺偏角19.3±2.5°,掌倾角及尺偏角改变差异无统计学意义(
P
<
0.05)。末次随访时所有患者均达骨愈合,平均愈合时间3.6月。术后1年腕背伸50.7±6.3°,掌屈49.4±6.1°,DASH评分15.0±6.3,Mayo腕关节功能评分24例优良,患侧握力平均为对侧84.4%。无内植物松动病例,2例浅表伤口感染,1例发生伸肌腱激惹症状。
结论
2
对于复杂桡骨远端骨折,掌侧锁定钢板结合背侧微型钢板能有效固定粉碎性关节面骨折块,利于早期功能锻炼及腕关节功能恢复,肌腱刺激症状发生率低。
Objective
2
To investigate the efficacy of volar anatomical locking plates combined with dorsal mini-plates in treating complex distal radius fractures.
Methods
2
We retrospectively included patients with complex distal radius fractures who had been treated with volar locking plates and dorsal mini-plates at Chongqing General Hospital from January 2019 to June 2023. The quality of articular surface fragment reduction was assessed through image analysis. Follow-up data included the Mayo wrist score,Disabilities of the Arm,Shoulder,and Hand Questionnaire(DASH) score,wrist range of motion,time to fracture healing,and complications.
Results
2
Twenty-eight patients(19 males,9 females; mean age,45.4±11.9 years) were included,with a mean follow-up of 14.9±3.6 months. Their injury mechanisms included falls from height(11 cases),traffic accidents (9 cases),and simple falls(8 cases). After operation,the volar tilt was 5.1±4.9°,and the ulnar inclination was 19.8±2.8°; at the final follow-up,the angles were 5.2±4.8° and 19.3±2.5°,respectively,neither showing any significant change (
P>
0.05). At the final follow-up,all fractures healed,with a mean healing time of 3.6 months. At 1 year after operation,the wrist extension was 50.7±6.3°; the wrist flexion was 49.4±6.1°; the DASH score was 15.0±6.3; the Mayo wrist scores were excellent or good in 24 cases; the grip strength of the affected side averaged 84.4% of that of the contralateral side. No implant loosening occurred. Two cases of superficial wound infection and one case of extensor tendon irritation were reported.
Conclusion
2
Locked volar plating combined with dorsal mini-plating provides stable fixation for comminuted articular surface fragments in complex distal radius fractures,enabling early functional rehabilitation with favorable wrist recovery and low rates of dorsal tendon irritation.
