Arthroscopic Glenoid Bone Tunnel and Half Bundle of Peroneus Longus Tendon-Based Subscapular Sling Procedure and...

The arthroscopic subacromial sling procedure is used to treat recurrent anterior shoulder instability. As an arthroscopic technique with less potential for complications, the subscapular sling with a half bundle of the peroneus longus tendon provides both dynamic and static stability. This procedure uses the half bundle of the peroneus longus tendon graft as a sling around the upper two-thirds of the subscapular tendon, with the graft attached to the anterior glenoid rim through the glenoid bone tunnel. We change the method of obtaining and fixing the graft during the subscapular sling procedure. The half bundle of the peroneus longus tendon has sufficient strength and diameter and reduces the risk of complications. The establishment of the glenoid bone tunnel can provide a more stable fixation for the graft, facilitating stable tendon-bone healing. This arthroscopic subscapular sling procedure with glenoid bone tunnel and half bundle of the peroneus longus tendon graft can be considered an alternative to existing surgical treatment options for recurrent anterior shoulder instability.
