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

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

Posterolateral Rotatory Instability of the Elbow: Part II. Supplementary Examination and Dynamic Imaging Techniques

Currently, a number of examination and imaging techniques exist for diagnosing posterolateral rotatory instability of the elbow. Although the posterolateral rotatory drawer is the primary examination maneuver, other special tests include the lateral pivot-shift test, prone push-up test, chair push-up test, and tabletop push-up test. In addition, posterolateral rotatory instability can be evaluated using radiography, magnetic resonance imaging, dynamic fluoroscopy, or dynamic ultrasound. In this Technical Note, each of these tests is described in detail. Video instruction is also provided to further explain the techniques and provide examples of positive tests

Posterolateral Rotatory Instability of the Elbow: Part I. Mechanism of Injury and the Posterolateral Rotatory Drawer Test

Posterolateral rotatory instability (PLRI) is the most commonly encountered pattern of elbow instability. It is the result of disruption of the lateral collateral ligament complex leading to a posterolateral rotatory subluxation of the ulna and radial head. A number of examination maneuvers have been described to assist in clinical identification of PLRI. Despite this, some inconsistency in the description of these techniques remains in the orthopaedic literature. This Technical Note details the mechanism of injury and patient presentation, and emphasizes the primacy of the posterolateral rotatory drawer test in the assessment of PLRI while providing video instruction on how it should be performed

Knotless Arthroscopic Repair of Subscapularis Avulsion Fracture Using a Single Anterior Portal

Proximal humerus lesser tuberosity avulsions are uncommon injuries; however, when present, they can be debilitating for patients. As such, they pose a unique clinical challenge. These fractures were traditionally treated through an open approach to the proximal humerus; however, arthroscopic techniques continue to evolve and are increasingly used for these types of injuries. We describe our minimally invasive arthroscopic technique to repair lesser tuberosity avulsions using standard arthroscopic equipment. This method is safe, efficient, and applies basic shoulder arthroscopic techniques

Arthroscopic Preparation and Internal Fixation of an Unstable Osteochondritis Dissecans Lesion of the Knee

We present our arthroscopic technique for fixation of an unstable osteochondritis dissecans (OCD) lesion. This technique includes arthroscopic evaluation of cartilage and bone quality of the OCD fragment, hinging open the lesion, debridement of fibrous nonunion tissue, reducing the fragment, and obtaining multi-point compression screw fixation. This technique avoids the morbidity of an open arthrotomy and should be considered when treating an unstable OCD lesion with adequate bone for fixation

Arthroscopic Fixation of Glenoid Rim Fractures After Reduction by Labral Repair

Surgical fixation of displaced, intra-articular glenoid fractures represents a clinical challenge. These fractures have traditionally been treated through open approaches to the glenohumeral joint; however, the morbidity associated with open surgery may be reduced with arthroscopic techniques. Previously described arthroscopic methods commonly use clamps and/or Kirschner wires to obtain and maintain provisional fixation. We describe our technique for minimally invasive, arthroscopic fixation of glenoid rim fractures using labral repair as an indirect reduction maneuver, followed by final fixation with an extra-articular screw. This method is safe, efficient, and reliable, and it can be used to approach a variety of intra-articular glenoid fractures

Arthroscopic Removal of Symptomatic Proximal Humerus Locking Plates With Bone-Void Filler Augmentation

Open reduction internal fixation of proximal humerus fractures is often accomplished with proximal humerus locking plates. While these plates have a good track record, they can become symptomatic and require removal once the fracture has healed. Open hardware removal is associated with a number of additional risks to the patient, including infection, scarring, nerve damage, and blood loss. In addition, the recovery time after open hardware removal may be prolonged, thereby predisposing the patient to postoperative stiffness. The purpose of this article is to describe a technique for removing proximal humerus locking plates arthroscopically. Although technically demanding, the benefits of this technique include smaller incisions, quicker recovery time, decreased risk of infection, and reduced blood loss. Arthroscopy also provides the surgeon with the ability to address concomitant intra-articular pathology at the time of surgery. Additionally, we use a bone-void filler to reduce the risk of fracture through stress caused by previous screw holes

Single-Incision Technique for Repair of Distal Biceps Tendon Avulsions With Intramedullary Cortical Button

Patients who experience distal biceps tendon avulsions generally benefit from surgical intervention. Compared with nonoperative treatment, surgery has shown improved muscle endurance as well as increased flexion and supination strength. Although a number of surgical techniques exist, repair of the distal biceps through a single incision is gaining popularity. This may be due in part to patient preference and emerging technologies such as cortical button fixation, suture anchors, and intraosseous screws. In this report, we present a simple technique for anatomically repairing distal biceps injuries using an intramedullary tenodesis button. This technique has the benefit of using a single unicortical drill hole in the radius while allowing the surgeon to sequentially tighten the tendon to its desired level of tension. When appropriate surgical steps are followed, it can be completed in a reliable, safe, and efficient manner through a single incision

Arthroscopic Psoas Management: Techniques for Psoas Preservation and Psoas Tenotomy

The iliopsoas tendon is an important dynamic stabilizer of the hip joint, and it should be carefully identified and preserved during routine hip arthroscopy. However, it may also be a source of hip pain manifesting as iliopsoas tendinitis or a snapping hip or contributing to the development of labral pathology caused by psoas impingement. In the appropriately indicated, refractory cases of iliopsoas-related hip pain, surgical intervention in the form of an iliopsoas tenotomy at the level of the labrum can result in reliable pain relief. We describe a method to identify and protect the iliopsoas tendon during routine hip arthroscopy when preservation is desired. In addition, we detail how to deepen the psoas tunnel if psoas impingement is present but psoas tenotomy is contraindicated. We also describe a reproducible technique of arthroscopic iliopsoas tenotomy using standard portals and minimal equipment when indicated

Creating and Closing the T-Capsulotomy for Improved Visualization During Arthroscopic Treatment of Femoroacetabular Impingement

Treatment of femoroacetabular impingement through an arthroscopic approach has gained widespread popularity in recent years. Although outcomes are generally favorable, one of the most common reasons for failure is incomplete resection of cam lesions of the femoral neck. As a result, the T-capsulotomy has been introduced as a method for improving access to the femoral head-neck junction, which is not always visible through a standard interportal capsulotomy. The T-capsulotomy has the benefits of improving arthroscopic visualization of the femoral neck, reducing overall fluoroscopy exposure for the patient and surgeon, and facilitating capsular plication. We present a reliable and efficient method for creating and repairing the T-capsulotomy. We routinely perform this technique in patients with cam lesions that are too large or too distal to safely visualize and decompress through an interportal capsulotomy
