关节镜下双Endobutton固定尺骨冠状突骨折（开放获取）

Arthroscopic double Endobutton fixation of ulnar coronoid process fracture (OA)

摘要:

[目的] 介绍全肘关节镜下双 Endobutton 固定尺骨冠状突骨折的手术技术及初步临床结果。[方法] 1 例 29 岁男性患者，经 X 线检查确诊为左 Regan-Morrey 2 型尺骨冠突骨折，采用全肘关节镜下手术治疗。术中采用臂丛神经阻滞麻醉，经关节镜进行操作，使用 1.2 mm 克氏针做骨隧道，并利用双 Endobutton 配合超强缝线进行固定。术后行常规护理及康复锻炼。 [结果]手术时间 1 h 50 min，术后 1、3 个月随访时，患者 Mayo 肘关节功能评分分别为 75、100 分。术后 3 个月随访显示骨折已愈合，肘关节功能恢复良好，肘关节活动度为-5°~140°。[结论] 全肘关节镜下双 Endobutton 固定尺骨冠状突骨折是一种有效的治疗方法，具有操作简便、固定效果可靠、术后康复快速的优势。

Abstract:

[Objective] To introduce the surgical technique and preliminary clinical results of double Endobutton fixation of ulnar coronoid process fracture under arthroscopy. [Methods] A 29-year-old male patient was diagnosed with left Regan-Morrey type 2 ulnar coronoid process fracture by X-ray, and was treated with total elbow arthroscopic surgery. As brachial plexus block anesthesia was performed, the portals were established for arthroscopy and instruments. The parallel bone tunnels was created with 1.2mm Kirscher's wire as the fracture fragment were reduced by locator, double Endobutton-suture loops were introduced and tightened to finish the fracture fixation. Routine nursing and rehabilitation exercise were carried out after operation. [Results] The patient had operation conducted smoothly with operation time of 1 hour and 50 minutes. The Mayo score was of 75 and 100 respectively, 1 and 3 months postoperatively. The patient had fracture healed with elbow function recovered well, and the elbow motion range from -5° to 140°. [Conclusion] This complete elbow arthroscopic double Endobutton fixation of ulna coronoid process fracture is an effective treatment method, with advantages of simple operation, reliable fixation and rapid postoperative recovery.
