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

ABSTRACT:

Background

Reconstruction 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.

Methods

Following 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.

Results

Spherical 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.

Conclusion

Currently 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.

Posterior shoulder dislocation with reverse Hill-Sachs lesion. A technical note and report of two cases.

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.

Arthroscopic Reduction of a Chronic Locked Posterior Shoulder Dislocation.

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.

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.

Posterior Endoscopic Cervical Decompression: Review and Technical Note.

Project description:Endoscopic spine surgery for the treatment of degenerative spinal diseases from lumbar to cervical spine has accelerated over the past 2 decades. Posterior endoscopic cervical discectomy (PECD) has been described as a safe, effective, and minimally invasive procedure for cervical radiculopathy or even part of the myelopathy. This procedure also has been validated with comparable outcomes to open and microscopic surgery. Radiculopathy due to foraminal disc herniation or foraminal stenosis should be the optimum indications of this procedure. Intraoperative 3-dimensional navigation can help surgeons to get quick and great quality guidance for endoscopic surgeons. In this review, we will focus on the technical details and evidence-based results of PECD which is a promising procedure for cervical radiculopathy with the advantages of a minimally invasive method.

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 a Coracoid Fracture Associated With Acromioclavicular Dislocation: Technical Note.

Project description:Operative management of a coracoid process fracture is indicated in case of painful nonunion, displacement of more than 1 cm, or multiple disruptions of the superior shoulder suspensory complex. Several techniques have been described with open reduction of the fracture and internal fixation using cortical screws with or without additional fixation of the acromioclavicular joint. This Technical Note aims to introduce an alternative safe, minimally invasive method for arthroscopic fixation of a coracoid fracture with simultaneously reduction of the acromioclavicular joint. The described arthroscopic technique might be helpful for shoulder surgeons who want to fix the coracoid process while avoiding the disadvantages of an open approach.

Arthroscopic Humeral Bone Tunnel-Based Tendon Grafting and Trapezius Transfer for Irreparable Posterior Superior Rotator Cuff Tear.

Project description:Irreparable posterior rotator cuff tears pose challenges to orthopaedic surgeons, especially when the medial remaining rotator cuff is not reusable. Trapezius transfer is biomechanically favorable due to the similar vector of the transferred muscle to the native posterior superior rotator cuff. Regarding combined tendon grafting in trapezius transfer, onto-surface tendon attachment to the humerus was reported in most previous reports. For better tendon-humeral head connection, we introduce an humeral bone tunnel-based tendon grafting technique. In this technique, we use the hamstring tendons and the anterior half of the peroneus tendon to make 3 grafts. The most critical steps of this technique are the proper creation of the humeral tunnels and graft implantation. We consider the introduction of this technique will shed light in the field of trapezius transfer for Irreparable posterior rotator cuff tears.

Soft Arthroscopic Latarjet Procedure: Technical Note on Biceps Tendon as a Modified Sling for Restoration of Glenohumeral Stability.

Project description:As an alternate to sling glenohumeral restabilization mechanism of Latarjet procedure, recent different arthroscopic soft-tissue reconstructive techniques have been described for the management of glenohumeral instability. One of these techniques is trans-subscapularis bony tenodesis of long head of biceps (instead of coracoid graft transfer) to the anteroinferior glenoid. For simplification of the latter technique, the current article reports an alternative arthroscopic technique for management of glenohumeral instability in patients with type V SLAP lesion or poor soft-tissue quality of the anterior capsulolabral complex. In this technique, Bankart repair is followed by soft-tissue tenodesis of long head of biceps to upper border of subscapularis tendon by 2 simple stitches of non-absorbable sutures. Compared with previous ones, the currently reported technique is versatile, quick, technically simple, entirely intra-articular, and cost-saving; however, it is nonanatomic and should be investigated in biomechanical and cohort clinical studies to clarify its long-term validity.
