Project description: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.

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.

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.

Project description:Epilepsy is a pathological condition characterized by seizures of muscle tension and convulsions in which the patient is unable to control himself, resulting in various complications and injuries. In this paper we talk about a rare case that combines a shoulder dislocation with a fracture of the surgical neck of the humerus after an epileptic seizure. The patient came to the hospital with clinical symptoms directed at dislocating the shoulder after an epileptic seizure, but careful examination and radiography revealed the presence of a fracture of the surgical neck of the humerus, so the management needed experience to repair two serious traumatic injuries. In the light of the foregoing, the need for clinical knowledge regarding such injuries in terms of diagnosis and methods of management and treatment is very necessary especially that neglect or wrong diagnosis will lead to very bad results, the most important of which are chronic pain, disability and stiffness.

Project description:Posterior shoulder dislocation (PSD) with a reverse Hill-Sachs lesion is a rare injury with challenging management. This article is a technical note, describing the combination of both, modified McLaughlin procedure with posterior Bankart repair, for the surgical treatment of traumatic PSD associated with a substantial reverse Hill-Sachs lesion. Two patients with mid-term follow-up are presented. Approaching and repairing both sides of the joint, balance and congruency are restored, the humeral head is centralized in the glenoid and the patient starts early mobilization and rehabilitation safely.

Project description:Anterior capsule ligament deficiency occurs in complicated anterior shoulder dislocation and poses a challenge to surgeons because of the irreparability of the capsule labrum structure or the nonoptimal healing potential after repair. Single-sling augmentation with either conjoined tendon or the long head of the biceps brachii has been reported to enhance the anterior stability of the shoulder. However, single-sling augmentation may still not be enough in cases of complicated anterior shoulder dislocation. Thus we introduce a double-sling anterior shoulder augmentation technique in which both the conjoined tendon and the long head of the biceps brachii are transferred to the anterior inferior side of the glenoid. Our clinical experience indicates that this procedure is effective to address complicated anterior shoulder dislocation. We believe that the introduction of this technique will provide a special choice in the treatment of anterior shoulder 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.

Project description:Recurrent anterior shoulder dislocation is always combined with glenoid and capsule-labrum deficiency. To address all these deficiency in a single operation, we developed a 4-layer structural reconstruction technique at the anterior side of the shoulder, which includes capsule-labrum repair, glenoid bone grafting, and transfer of the long head of the biceps brachii (LHB). This procedure is indicated in patients who need both sling and bone fragment augmentation. The critical steps of this technique are LHB transfer and 2-layer glenoid bone grafting. We believe that this technique will enhance the field of anterior shoulder reconstruction for complicated anterior shoulder dislocation.

Project description:Posterior glenohumeral instability (PGHI) is a commonly under- and misdiagnosed pathology owing to its variety of clinical presentations. In order to facilitate diagnosis and treatment, the simple yet comprehensive ABC classification for PGHI is based on the underlying pathomechanical principles and current standard of treatment. Three main groups of PGHI are distinguished based on the type of instability: A (first time), B (dynamic), C (static). Two subtypes further differentiate these groups in terms of their specific pathomechanism and provide a guideline in the choice of appropriate treatment: A (1, subluxation; 2, dislocation), B (1, functional; 2, structural), C (1, constitutional; 2, acquired). While conservative treatment is warranted in most patients with type 1 PGHI (A1, B1, C1), surgical treatment should be considered on an individual basis in patients with type 2 PGHI (A2, B2, C2), while keeping in mind that the different groups and subtypes can overlap, co-exist, or even progress from one to another over time. Of course the necessity for surgical treatment depends on the extent of the structural defects, on the severity of symptoms, on the chronicity, as well as on patient-specific functional demand, age, and health status. Nonetheless, the ABC classification helps to correctly diagnose the type of PGHI and provides a guideline for the generally recommended type of treatment.

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.
