慢性肩鎖関節離開に対する半腱様筋腱を用いた関節鏡視下ファイバーテープ増強烏口鎖骨靭帯再建術

This article describes an improved arthroscopic, drill-free technique for chronic acromioclavicular joint separations, avoiding the risks of coracoid or clavicular fracture associated with bone tunnels. The technique eliminates bone drilling by passing No. 5 sutures and FiberTape (Arthrex) around the coracoid base and clavicle. A semitendinosus tendon graft is guided doubly around this path using the sutures. This creates a FiberTape-tendon complex that replicates native coracoclavicular ligament function, offering vertical stability and biological integration for long-term healing. This approach offers a safe, effective solution for chronic acromioclavicular joint instability.
