【摘要】：目的探讨改良肘关节前内侧入路治疗尺骨冠状突骨折的临床疗效。方法 2010年1月—2014年12月,采用改良肘关节前内侧入路治疗13例尺骨冠状突骨折患者。其中,男10例,女3例;年龄18~57岁,平均37.2岁。致伤原因:交通事故伤5例,高处坠落伤7例,硬物撞击伤1例。损伤类型:肘关节恐怖三联征7例,冠状突骨折合并同侧桡骨头骨折4例,尺、桡骨近端关节内粉碎双骨折1例,冠状突骨折合并同侧桡骨远端骨折1例。尺骨冠状突骨折按照Regan-Morrey分型:Ⅱ型2例,Ⅲ型11例;按照O’Driscoll分型:冠状突前内侧面骨折10例(Ⅱb型8例、Ⅱc型2例),基底部骨折3例。记录尺骨冠状突骨折复位内固定手术时间、术中出血量以及相关并发症发生情况。通过X线片及临床检查判断骨折是否愈合,记录愈合时间。测量肘关节屈伸、旋转活动度,根据Mayo肘关节功能指数(MEPI)评价肘关节功能。结果手术时间为30~55 min,平均38.7 min;术中出血量为90~160 mL,平均109.3 mL。术后切口均Ⅰ期愈合,无医源性血管、神经损伤发生。患者均获随访,随访时间13~24个月,平均16.9个月。骨折均达临床愈合,愈合时间8~16周,平均11.2周;2例异位骨化形成。末次随访,肘关节活动度屈119~145°,平均132.4°;伸 8~15°,平均7°;前臂旋前68~90°,平均78.6°;旋后76~90°,平均84.3°。MEPI为70~100分;其中优9例,良3例,可1例,优良率92.3%。结论改良肘关节前内侧入路治疗尺骨冠状突骨折,可以避开肘部重要血管、神经,直视下进行骨折块复位、固定,是一种安全、简便、有效的手术入路。
[Abstract]:Objective to investigate the clinical effect of modified anterior medial elbow approach in the treatment of coronoid process fracture of ulna. Methods from January 2010 to December 2014, 13 patients with fracture of ulnar coronal process were treated with modified anterior medial approach of elbow joint. Among them, 10 cases were males and 3 cases were females, the age was 1857 years (mean 37.2 years). The causes of injury were traffic accident in 5 cases, falling injury in 7 cases and hard object impact injury in 1 case. The types of injury were as follows: 7 cases of elbow joint terror, 4 cases of coronal process fracture with ipsilateral radial head fracture, 1 case of comminuted double fracture of ulnar and proximal end of radius, 1 case of coronal process fracture with ipsilateral distal radius fracture. According to Regan-Morrey classification of ulnar coronal process fracture: type 鈪，
