Arthroscopic Reduction of a Chronic Locked Posterior Shoulder Dislocation.

ABSTRACT: Posterior shoulder dislocation is a rare condition. It is easily overlooked and often appears in a chronic locked status, which makes the reduction difficult, even through open procedures. Few reports in the literature have described an isolated arthroscopic reduction because it is difficult to elevate the humeral head to the level of the glenoid surface and obtain anterior-posterior soft-tissue balance. On the basis of an analysis of the mechanisms of the locking of the humeral head and the soft-tissue imbalance, we describe a set of arthroscopic shoulder release and reduction techniques, which include mainly the removal of rotator interval tissue; a thorough subscapularis release from the coracoid, the conjoined tendon, and the glenoid; and a 360° capsule-muscle release from the glenoid and the scapula. The described technique is an effective method to obtain a medial-to-lateral humeral head reduction and anterior-to-posterior soft-tissue balance. The introduction of this technique will provide a practical tool for surgeons to realize an arthroscopic shoulder reduction in the case of a chronic locked posterior shoulder dislocation.

Arthroscopically Assisted Reduction in a Chronic Locked Posterior Shoulder Dislocation.

Project description:Neglected posterior shoulder dislocation is a difficult condition in terms of decision making and surgical technique. Not only the bony deformity but also the soft tissue and patient's underlying disease are of concern. Whether the poor results are associated with a time delay or the treatment method is not clear yet. To date, there is neither a consensus nor treatment guidelines. We describe an arthroscopically assisted reduction and open McLaughlin procedure. The advantage of this procedure is preservation of the soft tissue of the anterior part of the shoulder during the surgical reduction technique for chronic neglected posterior shoulder dislocation cases.

Arthroscopic Management of Locked Posterior Shoulder Dislocations.

Project description:Locked posterior shoulder dislocations occur relatively uncommonly but pose aunique array of challenges for the treating surgeon. Posterior labral detachments and capsular damage along with reverse Hill-Sachs lesions are commonly present in these patients and must often be addressed at the time of surgical intervention. Multiple open and arthroscopic procedures that address these pathologic lesions have been described. Arthroscopic shoulder stabilization for patients with locked posterior shoulder dislocations for whom significant posterior instability and subluxation persist following closed reduction is described. A specific patient who underwent both arthroscopic posterior stabilization and supplemental advancement of the subscapularis into the reverse Hill-Sachs defect serves as a case example of this technique.

Posterior Glenohumeral Capsular Reconstruction With Modified McLaughlin for Chronic Locked Posterior Dislocation.

Project description:Posterior instability is relatively rare when compared with anterior instability but can comprise up to 40% of operatively treated instability cases. Posterior dislocations are much rarer and are classically due to trauma, seizure, or electric shock. Due to a lack of an obvious deformity and an internally rotated and adducted arm position, posterior shoulder dislocations often are missed on initial presentation. In the management of posterior dislocations, considerations need to be made in regard to bony and soft-tissue pathology. In the setting of soft-tissue deficiency, previous options included nonoperative management primarily consisting of bracing and activity modification as well as arthroplasty options that do not rely on the capsulolabral complex for stability. In this paper, we present a technique for treating a chronic posterior shoulder dislocation with an associated large reverse Hill-Sachs deformity. In this setting, a revision labral repair and capsulodesis is generally not possible due to insufficient capsulolabral tissues. Here, we present the technique for an arthroscopic posterior capsule reconstruction using an acellular dermal allograft as well as a McLaughlin procedure for the treatment of a reverse Hill-Sachs lesion.

Single-Portal Arthroscopic Posterior Shoulder Stabilization.

Project description:Posterior shoulder instability occurs when the labrum detaches posteriorly from the glenoid owing to significant trauma and is a relatively uncommon type of shoulder dislocation. Although posterior instability has often been treated with open shoulder stabilization, modern arthroscopic procedures are being rapidly pursued by surgeons as an improved option because of decreased invasiveness and reduced operative times. Arthroscopic stabilization of the posterior glenoid labrum typically involves 2 working portals, but the procedure still yields successful results when performed with a single posterior portal and a suture passer. Our technique involves 1 less portal to reduce invasiveness, lower the risk of nerve damage, and decrease the operative time and postoperative pain. The purpose of this article is to describe an arthroscopic posterior stabilization technique with a single working portal.

Chronic locked posterior gleno-humeral dislocation: technical note on fibular grafting for restoration of humeral head sphericity.

Project description:BackgroundReconstruction of reverse Hill-Sachs defect using osteo-chondral allograft has the advantages of spherical re-contouring and provision of smooth biological articular surface of the reconstructed humeral head. However, worldwide availability and risk of disease transmission of osteo-chondral allograft remain points of increasing concerns. As an alternative to lacking osteo-chondral allograft, the current technical note describes a reconstructive technique of reverse Hill-Sachs defect using autologous fibular grafting.MethodsFollowing open reduction of the dislocated humeral head, reverse Hill-Sachs defect was reconstructed using 3-4 autologous fibular pieces (each is of 10 mm in length) fixed in flush with the articular cartilage using 4-mm cancellous screws. Defect reconstruction was then followed by modified McLaughlin's transfer and posterior capsulorrhaphy.ResultsSpherical contour of the humeral head and gleno-humeral range of motion were restored. Intra-operative dynamic testing of the reconstruct revealed no residual posterior gleno-humeral instability.ConclusionCurrently reported technique might offer advantages of graft availability, technical simplicity, familiarity and reproducibility, safety (i.e. no disease transmission) and bone preservation facilitating future revision management (if needed). Nevertheless, long-term outcomes of this technique should be investigated via further cohort clinical studies.

Arthroscopic "Bone Block Cerclage" Technique for Posterior Shoulder Instability.

Project description:Many open and arthroscopic techniques have been described to treat posterior glenohumeral instability. Multifactorial features of posterior shoulder instability pathoanatomy and varied patient characteristics have challenged the understanding of this condition and have led to dissimilar results, without a strong consensus for the most adequate technique to treat it. We describe an arthroscopic anatomical metal-free posterior glenoid reconstruction technique, using a tricortical iliac crest allograft with 2 ultra-high strength sutures (FiberTape Cerclage System; Arthrex, Naples, FL) with concomitant posterior capsulolabral complex reconstruction procedure.

Posterior shoulder dislocation in a 10-year-old child: Case report.

Project description:IntroductionShoulder dislocation is the most common type of all joints dislocations. It occurs when there is separation in the glenohumeral joint. Posterior dislocation accounts for less than 4% of all shoulder dislocations. In fact, it is misdiagnosed in 60-79% of the patients in the initial presentation. In children a posterior shoulder dislocation is usually caused by a congenital anomaly or in those who have ligamentous laxity. Traumatic posterior shoulder dislocation without fracture of the proximal humeral epiphysis in children is very rare, and only few cases have been reported.Case presentationThis report presents a rare case of a 10-year-old child with a traumatic posterior shoulder dislocation without fracture.Discussionthis patient present with a rare posterior dislocation, which is direct and without fracture. It does not present with a marked deformity and it is hard to detect without a complete physical examination and radiographic series.ConclusionPosterior shoulder dislocations are rare, and even more rare in children without fractures. It is easily missed and needs careful history taking, physical exam and correct x-ray view to reach the diagnosis.

Arthroscopic, Nonrigid Fixation of a Displaced Glenoid Fracture After Anterior Shoulder Dislocation.

Project description:Glenoid rim fractures are recognized as a risk factor for recurrent instability after anterior shoulder dislocation. In addition to traditional open treatments of bony Bankart lesions, several arthroscopic techniques of fixation and reconstruction recently have been described. We present a technique of arthroscopic nonrigid fixation for large glenoid rim fractures, as an alternative to existing procedures.

Arthroscopic Glenoid Bone Grafting With Soft Fixation for Recurrent Anterior Shoulder Dislocation.

Project description:Glenoid bone defect is a common structural deficiency in cases of recurrent anterior shoulder dislocation. Glenoid bone grafting is an effective method to address glenoid defect and promote labrum regeneration. In most previous reports, firm fixation of the bone grafts was conducted, but with obvious inconvenience. Thus, we introduce a special glenoid bone-grafting technique in which the bone fragments are placed to the anterior side of the glenoid through the rotator interval, with 1 inferior graft free of fixation and 1 superior graft fixed to the glenoid by suture suspension. This technique is indicated in patients with recurrent anterior shoulder dislocation with glenoid defect or needing osseous stimulation for labrum regeneration. The critical point of this technique is the proper use of special glenoid bone grafting instruments. We believe this technique will provide a special choice in the treatment of recurrent anterior shoulder dislocation.

Posterior Ankle Arthroscopic Reduction With Internal Fixation.

Project description:Current surgical techniques in ankle fracture management now include arthroscopic-assisted reduction and internal fixation. The need for minimally invasive fracture reduction techniques, which preserve soft tissue envelops and assists in overall anatomic reduction, can be refined and improved. The ankle is an ideal anatomic location for arthroscopic-assisted reduction and internal fixation due to the high incidence of intra-articular pathology and the poor long-term sequela of nonanatomic reduction. Thus, we propose using prone posterior ankle arthroscopic reduction internal fixation for posterior ankle fracture variants.
