Snapping triceps tendon is an increasingly recognized clinical entity, which is associated with a variety of pathologic factors. The causative factors include inherited structural or developmental variations, post-traumatic malalignment, and other reasons. The main complaint of patients with snapping lateral triceps are the snapping sensation, mild muscle weakness of elbow extension, with or without tenderness in distal triceps tendon. Many treatment options have been reported previously, including tendon resection and redirection.
We present the case of a 19-year-old boy with post-traumatic distal lateral head of triceps tendon dislocation who complained of extension weakness and snapping sensation in his left elbow. Then, we used two-strand-overhand locking (TSOL) knot combined with double pulley technique to redirect the snapping triceps tendon.
The patient recovered well after the operation without complaining of discomfort. This fixing and redirection tendon technique, described previously for repairing rotator cuff tears, may be applied in a similar fashion for the snapping triceps tendon with promising clinical results.
弹响三头肌腱是一种越来越被认识的临床实体，与多种病理因素有关。致病因素包括遗传结构或发育变异、创伤后对线不良和其他原因。外侧三头肌腱弹响的患者主要主诉是弹响感、肘部伸展的轻度肌肉无力，伴或不伴有远端三头肌腱压痛。以前已经报道了许多治疗选择，包括肌腱切除和重新定向。
我们介绍了一个 19 岁男孩的病例，他因外伤导致外侧头三头肌腱脱位，诉左肘部伸展无力和弹响感。然后，我们使用双股过顶锁结（TSOL）结合双滑轮技术来重新定向弹响的三头肌腱。
患者术后恢复良好，无不适主诉。这种固定和重新定向肌腱技术以前曾用于修复肩袖撕裂，也可以类似地应用于弹响三头肌腱，具有良好的临床效果。
