INTRODUCTION: Numerous techniques have been introduced for the treatment of acute acromioclavicular (AC) joint dislocation. We aim to report the midterm results of coracoclavicular (CC) stabilization with double augmentation for the acute AC joint dislocation. CASE DESCRIPTION: Forty-three patients who underwent surgery for acute AC joint dislocation were followed up for an average of 59.6 months (range 40-97). The study composed of two treatment groups: group S, with 25 patients, in whom two suture anchors were used; and group B, with 18 patients, in whom a suture anchor and a double flip-button device were used, however the techniques in both groups are based on the same principle which is double augmentation...

Chronic acromioclavicular (AC) instability is a rare posttraumatic shoulder condition that can lead to undesirable symptoms like persistent pain, muscle fatigue, loss of strength, or even scapular dyskinesis. It is well known that in these cases the superior functional results depend on the restoration of the anatomy and stability of the AC joint in both vertical and horizontal planes. Considering the ligaments degeneration and atrophy in chronic AC joint dislocations, we present an arthroscopic-assisted reconstruction of both the coracoclavicular and AC ligaments using autograft augmentation...

INTRODUCTION: The clavicle, humerus and acromioclavicular (AC) joint separately are very commonly involved in traumatic injuries around the shoulder. Acromioclavicular joint dislocation with distal clavicle fracture is a well recognized entity in clinical practice. AC joint dislocation with mid shaft clavicle fracture is uncommon and only few cases have been reported in literature. However, to the best of our knowledge, this is the first case report to describe an acromioclavicular dislocation with ipsilateral mid shaft clavicle, mid shaft humerus and coracoid process fracture...

We use an in situ heating holder within an aberration corrected transmission electron microscope (AC-TEM) to study the structure and dynamics of large closed grain boundary (GB) loops in graphene at the atomic level. Temperatures up to 800 °C are used to accelerate dynamic evolution of the defect clusters, increasing bond rotation and atomic addition/loss. Our results show that the large closed GB loops relax under electron beam irradiation into several isolated dislocations far apart from each other. Line defects composed of several adjacent excess-atom clusters can be found during the reconfiguration process...

BACKGROUND: Horizontal instability impairs clinical outcome following acute acromioclavicular joint (ACJ) reconstruction and may be caused by insufficient healing of the superior acromioclavicular ligament complex (ACLC). However, characteristics of acute ACLC injuries are poorly understood so far. Purposes of this study were to identify different ACLC tear types, assess type-specific prevalence and determine influencing cofactors. METHODS: This prospective, cross-sectional study comprised 65 patients with acute-traumatic Rockwood-5 (n = 57) and Rockwood-4 (n = 8) injuries treated operatively by means of mini-open ACJ reduction and hook plate stabilization...

PURPOSE: The optimal treatment for acute dislocation of the acromioclavicular (AC) joint remains unclear, and prior randomized trials did not reveal any significant improvements in the operative groups. However, it is clear that some patients treated nonoperatively are dissatisfied with their outcome and request surgical correction. This video demonstrates one method of repair of a chronic dislocation of the AC joint in a patient with significant symptomatology following nonoperative treatment of a high-grade AC dislocation...

In case of patients with spinal cord injury and concomitant acromioclavicular (AC) joint-dislocation the treatment is challenging, as in this special patient group the function of the shoulder joint is critical because patients depend on the upper limb for mobilization and wheelchair-locomotion. Therefore the goal of this study was to examine, if the treatment of chronic AC-joint dislocation using the Weaver-Dunn procedure augmented with a hook-plate in patients with a spinal cord injury makes early postoperative wheelchair mobilization and the wheelchair transfer with full weight-bearing possible...

Treatment of acute (≤4 weeks) high-grade acromioclavicular (AC) joint separation (types III-VI) is still controversial. Currently, the two modern techniques that are widely used include hook plate fixation and coracoclavicular (CC) ligament fixation using a suspensory loop device (tightrope, synthetic ligament or absorbable polydioxansulfate sling). These techniques are both reported to have superior clinical outcomes. This systematic review and meta-analysis aimed to assess and compare clinical outcomes of hook plate fixation versus fixation of the CC ligament using a loop suspensory fixation (LSF) device for the treatment of AC joint injury...

This reports presents the case of a combined clavicle fracture malunion and chronic Type IV acromioclavicular (AC) joint dislocation. The patient was seen acutely in the emergency department following a mountain bike accident at which time the clavicle fracture was identified and managed conservatively however the AC dislocation was not diagnosed. The patient presented 25 months following the injury with persistent pain and disability and was treated with clavicle osteotomy and AC stabilization. We document the clinical details, surgical treatment and outcome...

UNLABELLED: Few salvage procedures have been described after a failed Weaver-Dunn procedure. We hypothesized that it was possible to perform an all-arthroscopic revision with a reflected vascularized conjoint tendon into the distal resected clavicle (Vargas procedure) augmented by an artificial coraco-clavicular ligament. Two patients were enrolled. A minimum of 3-cm proximal conjoint tendon was dissected under arthroscopic control. The half-longitudinal conjoint tendon split, leaving its proximal end attached to the coracoid process, was made and incised transversely near the muscles fibers...

Fractures of the lateral end of the clavicle are common in pediatric patients; most of these fractures occur at the physeal level representing Salter Harris injuries. The vast majority of fractures of the lateral end of the clavicle are managed nonoperatively. In this report, we describe a unique type of fracture of the distal end of the clavicle in the pediatric patients in which the fracture occurs in the metaphyseal lateral clavicle with the proximal edge of the fracture displaced posteriorly through the trapezius muscle causing obvious deformity...
