掌侧入路锁定加压接骨板治疗桡骨远端骨折

Treatment of distal radius fracture using the locking compression plate through a volar approach

目的探讨掌侧入路锁定加压接骨板固定（locking-compression plate,LCP）治疗不稳定性桡骨远端骨折的疗效。方法选取自2011年3月~2014年3月,按AO分型为B型和C型不稳定性桡骨远端骨折72例,采用掌侧入路,桡骨远端锁定加压接骨板固定。结果随访时间6~36月,平均15月,所有病例均或随访。关节功能恢复优良率分别为93.4%。放射学评价术后1年时骨折掌倾角和尺偏角分别为（9.5±2.1）°和（20.9±5.9）°,均未见桡骨短缩,关节面台阶均小于1mm。结论掌侧入路LCP治疗B、C类型的桡骨远端骨折,术中副损伤少,血运破坏小。能够牢固维持术中恢复的解剖形状,利于患肢早期的功能锻炼,取得良好效果。

Objective To investigate the curative effect of locking compression plate（LCP） in the treatment of unstable distal radius fracture. Methods 72 patients with unstable distal radius fracture of B type and C type according to the AO classification were treated with locking compression plate through volar approach during March 2011 to March 2014. Results All the patients were followed up for 6 to 36 months（average 15 months）. The excellent and good rate of joint function recovery was 93.4%. The palmar tilt and inclination of catagmatic palms valued by radiology were（9.5±2.1） ° and（20.9±5.9） ° respectively one year after operation. All cases had no radius shortening and the articular surface drops were less than 1 mm. Conclusion LCP through the volar approach has advantages of less harmful damage and minor disturbance to blood supply in the treatment of distal radius fracture of B and C types, which can firmly hold the anatomical form recovered by operation for the early limb function exercise. It makes a well effect.
