Abstract:[Objective] To introduce the surgical technique and preliminary clinical results of arthroscopic treatment of habitual anteri-or glenohumeral dislocation through the subscapularis portal. [Methods] After general anesthesia, the patients was placed in supine posi-tion with the affected limb suspended at 40° of abduction, and the arthroscopy was inserted through the anterosuperior portal. Under ar-throscopic vision, a 16 gauge puncture needle, followed by a 1.0 mm Kirschner wire with self-made sleeves in different diameters were in-serted to establish the the subscapularis portal, with a tuber 4 mm in diameter placed. The anterosuperior portal was used to release, refreshand marke the positions of the anchors, while the subscapularis portal was used to insert the 2.8 mm anchors sequentially, with the farthestanchor located at 5∶30 (right shoulder) or 6∶30 (left shoulder) position. The glenoid labrum and capsule were repair with the routine tech-niques. [Results] All the patients underwent the arthroscopic procedures successfully without complications such as infection or vascularand nerve damage. Of them, 25 patients were followed up for an average of (12.0±0.3) months. Compared with those preoperatively, theASES score [(64.8±7.9), (95.0±3.9), P＜0.001] and Rowe score [(42.4±6.9), (92.4±6.8), P＜0.001] significantly improved at 12 months postsurgery. The excellent rate of postoperative shoulder joint function was of 100%. [Conclusion] This arthroscopic technique using subscapu-laris portal for treatment of habitual anterior glenohumeral dislocation is feasible and beneficial for anchor placement, does achieve satisfac-tory primary clinical outcomes.
