摘要:

文题释义:
冠状突骨折:尺骨冠状突骨折并不常见,且易于漏诊,合并冠状突骨折的复杂肘关节损伤中冠状突骨折多为粉碎性,此类损伤治疗棘手,临床治疗中,治疗冠状突需达到足够的肘关节稳定性以便早期肘关节功能锻炼,钢板能给予冠状突坚强内固定。
肘关节前侧入路:从肱动脉和正中神经之间显露肘关节前关节囊和冠状突,操作简单,视野广泛,可直接对冠状突骨折进行评估及固定,放置内固定时相对容易;操作时需特别保护肘关节前侧血管神经束。

背景:尺骨冠状突解剖特殊,紧邻血管神经,同时存在固定不牢固、复发不稳定、术后肘关节僵硬和疼痛等特点,使得治疗尺骨冠状突骨折充满挑战,尤其是复杂肘关节损伤中尺骨冠状突骨折。

目的:探讨肘关节前侧入路钢板内固定治疗复杂肘关节损伤中尺骨冠状突Regan-MorreyⅡ型或Ⅲ型骨折的效果。

方法:2012年9月至2017年5月对取得完整随访资料的16例合并尺骨冠状突骨折的复杂肘关节损伤患者实施了切开复位内固定治疗。11例为Regan-MorreyⅡ型骨折,5例为Regan-MorreyⅢ型骨折;14例合并桡骨头骨折,2例合并尺骨鹰嘴骨折。所有患者对治疗方案均知情同意,且得到医院伦理委员会批准。采用肘关节前侧入路,从正中神经和桡动脉之间给予尺骨冠状突骨折复位及钢板内固定,同时所有的桡骨头或尺骨鹰嘴骨折也给予内固定治疗。

结果与结论:①所有患者均取得了骨折块满意复位和坚强固定;②随访13-28个月,在末次随访中所有骨折均显示了骨性愈合,平均愈合时间为16.5周,平均屈曲-伸展弧为113.4°,肘关节于平均13.8°位屈曲挛缩,进一步屈曲弧度为127.2°,平均旋前弧72.5°,平均旋后弧为74.7°,平均前臂旋转弧为146.9°,11例患者取得了功能运动弧;③所有患者均对治疗结果满意,平均Mayo肘关节功能评分为90.3分,其中优11例,良5例;④结果表明,复杂肘关节损伤中的冠状突骨折可以有效通过肘关节前侧入路结合支撑钢板内固定来治疗,这种固定方式允许肘关节早期功能锻炼,并产生良好的治疗效果。

Abstract:

BACKGROUND: Ulnar coronoid process has special anatomy and it is adjacent to vascular nerve. It is characterized by weak fixation, unstable recurrence, postoperative elbow joint stiffness and pain. These make the treatment of ulnar coronoid process fracture, in particular in complex elbow joint injuries, challenged.

OBJECTIVE: To investigate the efficacy of internal fixation with steel plate through an anterior approach on ulnar coronoid process Regan-Morrey type II or type III fracture in complex elbow injury.

METHODS: Sixteen patients with complex elbow injury and ulnar coronoid process fractures who underwent open reduction and internal fixation were followed up between September 2012 and May 2017. Among these patients, 11 patients had Regan-Morrey type II fracture, 5 patients had Regan-Morrey type III fracture, 14 patients had humeral head fracture, and 2 patients had ulnar olecranon fracture. All patients provided written informed consent. This study was approved by the Medical Ethics Committee of Hong Hui Hospital, China. Ulnar coronoid process fractures were reduced and fixed with steel plate through the space between the median nerve and the radial artery using an anterior approach. At the same time, all radial humeral head and olecranon fractures were treated by internal fixation.

RESULTS AND CONCLUSION: All patients acquired acceptable reduction and firm fixation of fractured fragments. All of them were followed up for 13-28 months. At the final follow-up, solid osseous union was confirmed for all coronoid fractures. The average time to radiologic union was 16.5 weeks. The mean flexion-extension arc was 113.4°, the flexion contracture was 13.8°, and further flexion was 127.2°. The mean pronation arc was 72.5°. The mean supination arc was 74.7°, and the mean forearm rotation arc was 146.9°. 11 patients achieved functional arc of motion. All patients were satisfied with the treatment with the mean Mayo Elbow Performance score of 90.3 points. 11 patients achieved excellent elbow performance and 5 patients achieved good elbow performance. These results suggest that ulnar coronoid process fractures in complex elbow injury can be treated successfully with an anterior surgical approach. This approach allows for accurate and rigid internal fixation with steel plate and early functional exercise, resulting in a reasonable outcome.
