Project description:BackgroundShoulder instability is a relatively common problem. Even with contemporary surgical techniques, instability can recur following both open and arthroscopic fixation. Surgical management of capsular insufficiency in anterior shoulder stabilization represents a significant challenge, particularly in young, active patients. There are a limited number of surgical treatment options. The Laterjet technique can present with a number of intraoperative challenges and postoperative complication.Description of techniqueWe report an arthroscopic subscapularis tenodesis technique as a salvage procedure for challenging glenohumeral instability cases. Sutures are passed through the subscapularis tendon and capsule before they are tied as one in the subdeltoid psace. The rotator interval is closed with superior and medial advancement of anterior and inferior tissue. This technical note carefully describes this procedure with useful technical tips, illustrations, and diagrams.Patients and methodsTwo clinical cases are described involving patients with recurrent instability following failed surgery who were successfully managed with this procedure.ResultsBoth cases described resulted in improved shoulder stability, range of motion, and function following management with this surgical technique. This arthroscopic subscapularis tenodesis procedure is proposed as a useful alternative repair technique for cases of recurrent instability after failed surgery with isolated capsular insufficiency.ConclusionIt is believed that this arthroscopic subscapularis tenodesis technique can potentially provide similar outcomes to open bone block stabilization procedures, while reducing the risks associated with those procedures.

Project description:There are numerous arthroscopic techniques available to address anterior shoulder instability. Complications are various, and in pursuit of new treatment options, an alternative arthroscopic technique with less potential for complications has been developed. The novel subscapular sling with a semitendinosus graft provides both dynamic and static stability. This procedure uses a semitendinosus graft as a sling around the upper two-thirds of the subscapular tendon, attached to the anterior glenoid rim. The sling phenomenon present in the Latarjet procedure was the basis of the development. The efficacy of the subscapular sling procedure has been verified in biomechanical studies and further investigated in a clinical pilot study. The procedure can be performed without altering the anatomy of nearby structures such as the coracoid process, the conjoined tendon, and the axillary and musculocutaneous nerves. The authors propose the arthroscopic subscapular sling procedure as an alternative to existing surgical treatment options for recurrent anterior shoulder instability.

Project description:The treatment of chronic shoulder instability with poor quality of the anterior capsulolabral tissue is still controversial. In these cases the Latarjet procedure is certainly more effective in preventing recurrence than an arthroscopic capsular repair. However, several studies have reported a variety of severe complications related to the Latarjet procedure because of the use of bone augmentation and hardware implantation; moreover, the arthroscopic version of the Latarjet procedure is technically difficult and potentially dangerous because of the proximity of neurovascular structures. The aim of this report is to describe an innovative arthroscopic technique consisting of an augmentation of the anterior capsulolabral tissue using the articular portion of the subscapularis tendon and knotless suture anchors paired with high-strength tape for its fixation to the anterior glenoid edge. In the absence of severe bone deficiency of the anterior glenoid edge, this procedure can minimize arthroscopic technique failures, restoring the anterior capsulolabral wall without any significant reduction of shoulder functionality.

Project description:Posterior shoulder dislocations are an uncommon cause of glenohumeral instability; they are frequently missed and are associated with humeral head defects and capsulolabral lesions. Despite surgical treatment often being mandatory, there is still no standardized treatment for anterior impaction fractures of the humeral head (reverse Hill-Sachs lesions). Arthroscopic surgery is typically indicated, with a tendency toward resorting to knotless techniques in recent years. We present a method for the treatment of posterior shoulder dislocations with engaging reverse Hill-Sachs lesions that achieves full defect coverage using an arthroscopic all-in-the-box knotless subscapularis bridge technique with 2 anchors-with one crossing the subscapularis tendon and the other embracing it-along with posterior capsulolabral complex restoration. This promising technique is a potentially superior alternative for the treatment of these lesions that can also be used in the presence of concomitant partial subscapularis tears.

Project description:Although anterior shoulder instability is most commonly treated with arthroscopic fixation, open labral repair with capsular shift may be best for select patients and in cases of revision stabilization without significant bone loss. The technique described in this article uses the deltopectoral interval; it involves careful dissection of the subscapularis from the anterior capsule, repair of the Bankart lesion, and a lateral and superior capsular shift using all-suture anchors in the humeral head. Advantages of this technique include meticulous control of anchor placement and the ability to provide additional stability via a lateral and superiorly directed capsular shift. This operation can be performed in a reliable, efficient, and reproducible manner.

Project description:Open Bankart repair was the standard technique used in the past, but the request for less invasiveness, always pursued by every surgeon, pushed the development of the arthroscopic procedure. Nowadays the stabilization of the anteroinferior labrum is usually performed with an arthroscopic technique that uses the classic posterior portal and 2 anterior working portals. Because arthroscopy is progressing steadily under every aspect, there is now the chance to use only one working portal with the aid of a suture passer. One less portal not only means less invasiveness but also less postoperative pain and possible shorter operative time. This Technical Note is focalized in the description of a Bankart repair technique with a single working portal and the aid of a suture lasso.

Project description:Revision anterior stabilization of the shoulder presents a challenge to the surgeon and carries a higher risk of recurrent dislocation than primary repair. The Latarjet procedure may be more reliable than revision soft-tissue repair but may not be indicated in patients without significant glenoid bone loss. We describe an arthroscopic technique of conjoint tendon transfer using a combination of suspensory and interference screw fixation for patients without significant glenoid bone loss (<15%). The arthroscopic approach to this procedure allows intra-articular visualization to assist in mobilization of the conjoint tendon, accurate bone tunnel placement, and subsequent labral repair. It avoids the additional steps of bone block preparation and the larger portals required for arthroscopic Latarjet techniques, in addition to eliminating potential complications due to coracoid bone block resorption.

Project description:Anterior glenohumeral instability is a common clinical entity, particularly among young athletic patient populations. Nonoperative management and arthroscopic treatment of glenohumeral instability have been associated with high rates of recurrence, particularly in the setting of glenohumeral osseous defects. Coracoid transfer, particularly the Latarjet procedure, has become the treatment of choice for recurrent anterior glenohumeral instability in the setting of osseous deficiencies greater than 20% to 30% of the glenoid surface area and may also be considered for the primary treatment of recurrent instability in the high-risk contact athlete, even in the setting of limited osseous deficiency. The following Technical Note provides a diagnostic approach for suspected glenohumeral instability, as well as a detailed description of the congruent-arc Latarjet procedure, performed with a deltoid split, with its postoperative management.

Project description:Glenoid bone loss remains a significant risk factor for recurrent instability after shoulder dislocation. Several options exist for glenoid bone graft augmentation, including autograft and allograft options. Strengths and weaknesses exist for each. Graft fixation with screws remains a key concern for technical viability requiring a medial portal as well as the risk of graft osteolysis. Suture button suspensory fixation is a new technique recently described for arthroscopic iliac crest bone graft; however, no description exists concerning osteochondral graft fixation. We describe an arthroscopic technique for distal tibial allograft glenoid augmentation with suspensory suture button fixation. The rationale and technical aspects of this procedure are discussed.

Project description:Fresh distal tibia allograft (DTA) has been gaining popularity among surgeons as an anatomic reconstruction option for the treatment of significant glenoid bone loss. Fresh DTA results in a clinically stable joint with excellent clinical outcomes and minimal graft resorption, and it has similar outcomes as the Latarjet procedure. Proper graft preparation and fixation are critical to ensuring optimal outcomes. The purpose of this Technical Note is, therefore, to describe our updated technique for DTA preparation that highlights precise cutting anatomy, sizing options, and use of orthobiologics to optimize distal tibia graft union to the native glenoid surface.
