Arthroscopic Knotless Modified McLaughlin Procedure for Reverse Hill-Sachs Lesions.

ABSTRACT: 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.

Arthroscopic Knotless Subscapularis Bridge Technique for Reverse Hill-Sachs Lesion With Posterior Shoulder Instability.

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.

Arthroscopic treatment of a reverse hill-sachs lesion.

Project description:Acute traumatic posterior shoulder instability is a rare injury. Such injuries can result in significant bone defects of the anterior humeral head that require surgical intervention. In the past, small to medium defects have been treated by a soft-tissue or bone transfer into the lesion. We present an arthroscopic technique for addressing these lesions in which the middle glenohumeral ligament is sutured into the defect, thereby making it an extra-articular defect and preventing it from engaging the posterior glenoid.

Arthroscopic Knotless Remplissage for the Treatment of Hill-Sachs Lesions Using the PASTA Bridge Configuration.

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.

Arthroscopic McLaughlin Procedure for Treatment of Posterior Instability of the Shoulder With an Engaging Reverse Hill-Sachs Lesion.

Project description:Posterior shoulder dislocation is associated with an engaging reverse Hill-Sachs lesion (i.e., involving >25% of the articular surface of the humeral head) in 28% of cases, leading to posterior instability. Isolated capsulolabral fixation usually performed to treat posterior instability is not effective at stabilizing the shoulder when there is such a bony lesion. The original McLaughlin procedure, first described in 1952, consists of detaching the subscapularis tendon from the lesser tuberosity and transferring it to the bony defect by an open approach. Several open and arthroscopic modifications of this technique have been described since this description. This article describes a truly arthroscopic McLaughlin procedure. Arthroscopy allows complete visualization of the glenohumeral joint and allows associated posterior and anterior soft-tissue lesions to be addressed at the same time. Moreover, the morbidity of open procedures is avoided. Although this procedure is known to be effective at stabilizing the shoulder, further long-term studies are required to assess the functional outcomes.

Arthroscopic All-Inside Suture Bridge for Remplissage Procedure Treating Off-Tracking Hill-Sachs Lesions in Anterior Shoulder 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.

The Tripod-Pulley Technique for Arthroscopic Remplissage in Engaging Hill-Sachs Lesions.

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.

Arthroscopic Remplissage for Engaging Hill-Sachs Lesions in Patients With Anterior Shoulder Instability.

Project description:Anterior shoulder instability is often accompanied by a Hill-Sachs defect on the humeral head that can contribute to recurrent instability if not addressed at the time of surgery. We describe a method of performing arthroscopic remplissage to treat engaging Hill-Sachs lesions in patients with glenohumeral instability. It has the benefits of being an efficient procedure that can be performed with minimal technical difficulty and can be used to augment other stabilization procedures such as labral repair. The indications for this technique include the presence of an engaging Hill-Sachs defect in patients will little or no glenoid bone loss. In appropriately selected patients, arthroscopic remplissage has shown reduced rates of recurrent instability.

Arthroscopic Reduction and Balloon Humeroplasty in the Treatment of Acute Hill-Sachs Lesions.

Project description:Shoulder instability is often associated with an impaction fracture of the humeral head, commonly referred to as a "Hill-Sachs lesion." This lesion is present in both anterior and posterior instability. Forty percent to 90% of anterior shoulder dislocations have associated Hill-Sachs lesions, whereas 29% to 86% of posterior shoulder dislocations have reverse Hill-Sachs lesions. Both of these lesions can contribute to recurrent instability of the shoulder and require surgery to be treated. Currently, the most common procedures to address Hill-Sachs lesions are the remplissage procedure (transfer of the infraspinatus into the posterior humeral head defect), capsular shift, disimpaction technique, humeral head resurfacing, bone block transfer, or shoulder arthroplasty. Reverse Hill-Sachs lesions are managed with similar procedures, such as the remplissage-equivalent technique described by McLaughlin, which involves transfer of the subscapularis tendon to fill the humeral head defect. The procedure has the advantage of "exteriorizing" the humeral head defect, but in the case of large lesions, it can result in significant loss of the articulating articular surface. The purpose of this article is to describe an arthroscopically assisted disimpaction technique with supplemental grafting using a balloon osteoplasty technique for a reverse Hill-Sachs lesion with bone cement to support and maintain the reduction.

Arthroscopic Transfer of the Subscapularis Tendon for Treatment of a Reverse Hill-Sachs Lesion.

Project description:Posterior shoulder instability occurs less often than anterior shoulder instability but is increasingly recognized as a relatively common condition. The reverse Hill-Sachs lesion is present in some patients with posterior instability and is best described as an impaction fracture of the anterior humeral head. These reverse Hill-Sachs lesions can predispose the patient to recurrent instability events and may need to be addressed directly at the time of surgery. Multiple open and arthroscopic procedures have been described to transfer bone or soft tissue structures into this reverse Hill-Sachs defect. An arthroscopic technique for the transfer of the subscapularis tendon into the defect using a standard 30° arthroscope, standard portals, and suture anchors is described.
