OBJECTIVE Distal biceps brachii tendon (DBBT) rupture is an uncommon but functionally significant injury given the loss of supination, flexion strength and pain that often result. Prompt surgical repair is preferred in most patients. Clinicoradiological post-operative follow-up is typically performed to assess DBBT repair integrity and function, frequently using ultrasound, though to date, no studies have described post-operative DBBT repair sonographic appearances. The purpose of this study was to evaluate post-operative DBBT sonographic appearances in the context of Endobutton repair with the following aims:i.Establish typical ultrasound appearances 12 months post-surgeryii.Establish the relationship between ultrasound appearances and clinical/functional outcomes. MATERIALS AND METHODS Sixty patients between February 2016 and October 2017 undergoing DBBT repair were prospectively recruited, all undergoing clinical and sonographic assessment 12 months post-surgery. Ultrasound data was collected on tendon integrity, tendon calibre and presence of intratendinous calcification, peritendinous fluid and peritendinous soft tissue/scarring. Clinical data was collected on active range of motion (ROM) (flexion, extension, supination, pronation) and strength (flexion and supination). RESULTS A total of 57/60 patients had intact DBBT repairs identified sonographically and clinically at 12 months. DBBT repairs had significantly increased cross-sectional area (mean 260%, 95% CI: 217%, 303%) compared with non-operated DBBT. Ninety-three percent of DBBT repairs were hypoechoic. Thirty percent contained intratendinous calcification. Peritendinous fluid/soft tissue was rarely observed. There was no significant correlation between DBBT calibre and strength/ROM parameters. CONCLUSION Normal post-operative sonographic appearances of Endobutton DBBT repair comprise a hypoechoic tendon significantly increased in calibre compared with non-operated tendon ± intratendinous calcification. DBBT repair calibre varies greatly, but is not associated with any significant difference in strength/ROM.

Endobutton肱二头肌肱二头肌腱远端修复的临床和超声检查：什么构成正常的术后外观？

目的由于肱二头肌肱二头肌腱（DBBT）经常失去旋后，屈曲强度和疼痛，因此不常见，但在功能上很重要。在大多数患者中，首选及时进行手术修复。通常使用超声对临床放射学术后进行随访，以评估DBBT修复的完整性和功能，尽管迄今为止，尚无研究描述术后DBBT修复的超声检查表现。这项研究的目的是在Endobutton修复的背景下评估术后DBBT超声检查的表现，其目的如下：i。在手术后12个月建立典型的超声表现ii。建立超声表现与临床/功能结果之间的关系。材料与方法前瞻性招募了2016年2月至2017年10月之间接受DBBT修复的60例患者，所有患者均在手术后12个月接受了临床和超声检查。收集有关肌腱完整性，肌腱口径以及是否存在腱鞘内钙化，腱鞘液和腱鞘软组织/瘢痕的超声数据。收集有关活动活动范围（ROM）（屈曲，伸展，旋后，旋前）和力量（屈曲和旋后）的临床数据。结果共有57/60例患者在12个月的超声检查和临床检查中发现DBBT修复完整。与未操作的DBBT相比，DBBT修复的横截面积显着增加（平均260％，95％CI：217％，303％）。百分之九十三的DBBT维修是低回声的。30％的囊内钙化。很少观察到牙周液/软组织。DBBT口径与强度/ ROM参数之间没有显着相关性。结论Endobutton DBBT修复术后的正常超声检查表现为低回声肌腱，其直径与非手术肌腱±肌内钙化相比明显增加。DBBT修复口径差异很大，但与强度/ ROM的任何显着差异无关。结论Endobutton DBBT修复术后的正常超声检查表现为低回声肌腱，其直径与非手术肌腱±肌内钙化相比明显增加。DBBT修复口径差异很大，但与强度/ ROM的任何显着差异无关。结论Endobutton DBBT修复术后的正常超声检查表现为低回声肌腱，其直径与非手术肌腱±肌内钙化相比明显增加。DBBT修复口径差异很大，但与强度/ ROM的任何显着差异无关。
