Project description:Recurrent glenohumeral dislocations can produce Hill-Sachs lesions-bony defects on the humeral head resulting from the humerus hitting the glenoid during dislocations. Some of these lesions can engage on the glenoid during motion, producing instability and potentially affecting the success of a labral repair. The remplissage was developed to address these Hill-Sachs lesions and improve stability. French for "filling," the goal of the remplissage is to fill the Hill-Sachs lesion with the infraspinatus tendon, preventing the margins of the lesion from engaging with the glenoid. Analogous to restoring the rotator cuff footprint during repair, a primary goal of the remplissage is to have the infraspinatus cover the Hill-Sachs lesion. The partial articular supraspinatus tendon avulsion (PASTA) bridge was originally developed for partial-thickness rotator cuff repair in situ, but additional uses have been found in other settings. The PASTA bridge uses a medial row horizontal mattress with a lateral anchor to create a linked construct to effectively distribute force and provide adequate coverage of the lesion. Knotless anchor technology used in this procedure prevents the need for arthroscopic knot tying and potentially damaging knot stacks. This Technical Note describes a remplissage technique using the PASTA bridge configuration to address Hill-Sachs lesions associated with recurrent glenohumeral instability.
Project description:Hill-Sachs lesions are significantly correlated with recurrent anterior shoulder instability. The remplissage procedure is designed to fill a posterosuperior humeral head defect with the infraspinatus tendon and posterosuperior capsule in patients with off-track Hill-Sachs lesions. This Technical Note describes an arthroscopic all-inside suture bridge to gain more footprint contact area and tissue compression to improve healing. Moreover, it does not have the necessity of going through the subacromial space to retrieve and tie the sutures. Thus, the procedure reduces the operative time and improves reproducibility.
Project description:Arthroscopic Bankart repair is now a well-established technique for the treatment of shoulder instability. However, failure rates are considerable when significant bony defects are not addressed. Hill-Sachs lesions, present in the vast majority of those with recurrent anterior instability, when of significant dimension and location, may account for some of these failures. The remplissage procedure involves capsulotenodesis of the posterior capsule and the infraspinatus tendon to fill the Hill-Sachs lesion. "Double-pulley" remplissage is a transtendinous technique that has been described elsewhere and that may simplify the procedure. We present a modification of this technique, the "tripod-pulley" technique, which we feel may potentiate healing of the Hills-Sachs lesions of the capsule and infraspinatus by increasing the surface contact area. At the same time, this technique minimizes the risk of potential damage to the infraspinatus as it uses 2.3-mm "all-suture" anchors.
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:Posterior shoulder dislocations often are associated with an impression fracture involving the anterior humeral head known as a reverse Hill-Sachs lesion. These injuries can result in significant bone defects that require surgical management to prevent them from engaging the posterior glenoid. We present a modified arthroscopic, knotless McLaughlin procedure (tenodesis of the subscapularis tendon into the bone defect) for the treatment of small-to medium-sized, engaging Hill-Sachs lesions. The knotless fashion aims to eliminate potential problems associated with knot tying, such as knot migration, knot impingement, and chondral abrasion.
Project description:Hill-Sachs lesions (HSLs) can be present after a primary shoulder dislocation and may go unrecognized; this can alter the necessary bony constraint within the glenohumeral joint. To deal with HSLs, remplissage is a safe procedure with low complication rates, low recurrent instability rates, and good patient outcome scores compared with many of the other alternative techniques. On the other hand, a great number of techniques have been described to treat reverse Hill-Sachs lesions (RHSLs). In this article, we propose a method of treatment for combined simultaneous HSL and RHSL shoulder injuries. However, consensus on a specific treatment is yet to be established. We present an arthroscopic treatment guideline for patients with shoulder instability due to anterior and posterior labral lesions, HSL, and RHSL.
Project description:Hill-Sachs lesions are a common finding in patients with glenohumeral instability. There have been numerous methods described for addressing Hill-Sachs deformity. One popular method includes transferring a portion of the infraspinatus muscle into the posterior-superior defect (remplissage) to prevent the lesion from engaging and the resultant instability. We present a method of arthroscopic remplissage whereby the lesion is addressed through transtendinous insertion of arthroscopic anchors. Once 2 anchors have been inserted, 1 limb of each suture is tied to the other anchor, the so-called pulley repair technique. This can be performed either under direct visualization in the subacromial space or blindly while the surgeon is viewing from the articular side. Once both limbs have been tied, the infraspinatus tendon nicely spans the defect, and there has been minimal morbidity to the tendon itself. We have found this method to be useful for addressing a large Hill-Sachs deformity.
Project description:The arthroscopic remplissage procedure has gained popularity in recent years and is gaining acceptance as an excellent and safe procedure to perform in patients with large engaging Hill-Sachs lesions. The procedure was introduced as an arthroscopic procedure, but surgeons not familiar with the procedure often encounter many problems, which makes the procedure difficult and frustrating to perform. A technique for this procedure using a commercially available PASTA (partial articular supraspinatus tendon avulsion) repair kit is presented.
Project description:Remplissage decreases the risk of recurrence after arthroscopic stabilization for recurrent anterior instability. Traditionally, the procedure requires accessing the subacromial space, which adds time and morbidity to the procedure. This Technical Note describes an all-inside technique for knotless remplissage with 2 interconnected anchors. By avoiding knot tying or accessing the subacromial space, the efficiency of the procedure is improved.
