Injuries to extensor tendon are a common problem seen by hand surgeons. Most often, these injuries can be primarily repaired. On occasion, however, the injury may lead to an actual substance loss in the extensor tendon, precluding primary approximation of the cut ends. The hemilateral band technique provides a solution to this problem.
The hemilateral band technique involves creation of a new terminal slip to bridge gaps in the extensor tendon using half of each lateral band in the finger. This study included patients with extensor tendon injury in zone I. At final follow-up, the available range of motion at the distal interphalangeal joint was recorded.
Six patients were operated using the hemilateral band technique from 2007 to 2009. All patients had extensor tendon substance loss with average gap of 12 mm (5 to 20 mm). At final follow-up, which averaged 14 months, all patients had a good outcome with an average motion arc of 37 degrees. No patient showed loss of intrinsic function at the proximal interphalangeal joint because of harvesting half of each lateral band.
The hemilateral band technique is an effective method for reconstructing a gap deficiency in the terminal slip of the extensor tendon of a finger.
伸肌腱损伤是手外科医生常见的问题。大多数情况下，这些损伤可以进行一期修复。然而，有时损伤可能导致伸肌腱实质性缺损，无法对断端进行一期缝合。半侧束带技术为解决这一问题提供了一种方法。
半侧束带技术是利用手指每条侧束的一半来创建一个新的终末腱，以桥接伸肌腱的缺损。本研究纳入了Ⅰ区伸肌腱损伤的患者。在最终随访时，记录远端指间关节的可用活动范围。
2007年至2009年，6例患者采用半侧束带技术进行手术。所有患者均有伸肌腱实质性缺损，平均缺损间隙为12mm（5至20mm）。在平均14个月的最终随访中，所有患者预后良好，平均活动弧为37度。由于每条侧束只取用一半，没有患者出现近端指间关节内在肌功能丧失。
半侧束带技术是重建手指伸肌腱终末腱缺损的有效方法。
