There are many described surgical techniques for the treatment of recurrent anterior shoulder instability. Numerous authors have performed anterior bone block procedures with good results for the treatment of anterior shoulder instability with glenoid bone loss. The benefits of using arthroscopic procedures for surgical stabilization of the shoulder include smaller incisions with less soft-tissue dissection, better visualization of the joint, better repair accessibility, and the best possible outcome for external rotation. We describe an arthroscopic anteroinferior shoulder stabilization technique with an iliac crest tricortical bone graft and capsulolabral reconstruction. It is an all-arthroscopic technique with the advantage of not using fixation devices, such as screws, but instead using special buttons to fix the bone graft. The steps of the operation are as follows: precise placement of a specific posterior glenoid guide that allows the accurate positioning of the bone graft on the anterior glenoid neck; fixation of the graft flush with the anterior glenoid rim using specific buttons under arthroscopic control; and finally, subsequent capsular, labral, and ligament reconstruction on the glenoid rim using suture anchors and leaving the graft as an extra-articular structure.

Arthroscopic bone block grafting combined with a standard Bankart repair restored shoulder stability in patients with anteroinferior glenohumeral instability with glenoid bone deficit, with excellent clinical and radiological results. This procedure did not substantially limit external rotation, allowing a high rate of return to sports even among competitive, overhead, and "at risk" athletes.

Background: The aim is to describe a new arthroscopically assisted Latarjet technique. Methods: We evaluated the clinical and radiological findings of 60 patients with chronic recurrent anterior gleno-humeral instability who underwent, between September 2013 and November 2014, an arthroscopically-assisted Latarjet procedure with double round endobutton fixation. Inclusion criteria were: chronic anterior recurrent instability, Instability Severity Index Score (ISIS) greater than three points, a glenoid bone defect > 15% or a Hill Sachs lesion with concomitant glenoid bone defect > 10%. During surgery the joint capsule and the anterior glenoid labrum were detached. Two drill tunnels perpendicular to the neck of the glenoid were made through a guide. An accessible pilot hole through the glenoid was created to allows the passage of guidewires for coracoid guidance and final fixation onto the anterior glenoid. Through a restricted deltopectoral access a coracoid osteotomy was made. Finally, the graft was prepared, inserted and secured using half-stitches. Results: The mean follow-up was 32.5 months (range 24-32 months). At a mean follow-up, 56 of the 60 subjects claimed a stable shoulder without postoperative complaints, two (3.3%) had an anterior dislocation after new traumatic injury, and two (3.3%) complained of subjective instability. At the latest follow-up, four subjects complained of painful recurrent anterior instability during abduction-external rotation with apprehension. At 1 year, the graft had migrated in one patient (1.7%) and judged not healed and high positioned in another patient (1.7%). Moreover, a glenoid bony gain of 26.3% was recorded. At the latest follow-up, three patients had grade 1 according to Samilson and Prieto classification asymptomatic degenerative changes. Nerve injuries and infections were not detected. None of the 60 patients underwent revision surgery. Healing rate of the graft was 96.7%. Conclusions: This technique of arthroscopically assisted Latarjet combines mini-open and arthroscopic approach for improving the precision of the bony tunnels in the glenoid and coracoid placement, minimizing any potential risk of neurologic complications. It can be an option in subjects with anterior gleno-humeral instability and glenoid bone defect. Further studies should be performed to confirm our preliminary results.

Background: We prospectively tested technical feasibility and clinical outcome of percutaneous ultrasound-guided tenotomy of long head of biceps tendon (LHBT). Methods: We included 11 patients (6 women; age: 73 ± 8.6 years) with symptomatic full-thickness rotator cuff tear and intact LHBT, in whom surgical repair was not possible/refused. After ultrasound-guided injection of local anesthetic, the LHBT was cut with a scalpel under continuous ultrasound monitoring until it became no longer visible. Pain was recorded before and at least six months after procedure. An eight-item questionnaire was administered to patients at follow-up. Results: A median of 4 tendon cuts were needed to ensure complete tenotomy. Mean procedure duration was 65 ± 5.7 s. Mean length of skin incision was 5.8 ± 0.6 mm. Pre-tenotomy VAS score was 8.2 ± 0.7, post-tenotomy VAS was 2.8 ± 0.6 (p < 0.001). At follow-up, 5/11 patients were very satisfied, 5/11 satisfied and 1/11 neutral. One patient experienced cramping and very minimal pain in the biceps. Six patients had still moderate shoulder pain, 1/11 minimal pain, 2/11 very minimal pain, while 2/11 had no pain. No patients had weakness in elbow flexion nor limits of daily activities due to LHBT. One patient showed Popeye deformity. All patients would undergo ultrasound-guided tenotomy again. Conclusion: ultrasound-guided percutaneous LHBT tenotomy is technically feasible and effective.
