Background : The management of acromioclavicular joint injuries requires a thorough understanding of the anatomy and biomechanics of the joint, as well as knowledge of the pertinent physical exam findings and classification to determine an appropriate treatment approach, whether operative or nonoperative. In this article, we present a narrative review of the current state of understanding surrounding these issues. Although there are a large number of options for operative intervention, we additionally present our experience with anatomic coracoclavicular ligament reconstruction (ACCR) with imbrication of the deltoid fascia...

Regional anaesthesia for shoulder surgery remains challenging in patients with pre-existing respiratory comorbidities. Various alternative phrenic sparing techniques have been described in the literature, but to our knowledge, none have explored the benefits of using short-acting local anaesthetics in combination to achieve surgical anaesthesia for awake surgery. This case report describes the successful use of the superior trunk block catheter, a relative phrenic sparing shoulder nerve block, and 2% chloroprocaine, a short-acting local anaesthetic, to provide surgical anaesthesia for awake shoulder surgery in a patient with severe respiratory disease...

Eponymization serves as a means of paying tribute to individuals who have made significant contributions to our culture. Each eponym is often linked with a story for everyone to discover. To aid in the retention of these stories, this review offers readers an overview of the individuals behind the eponymous terms, as well as their original descriptions, within the context of acromioclavicular joint pathology and orthopaedic surgery.

PURPOSE: The aim of this study was to evaluate the clinical and radiological outcomes in the treatment of acute acromioclavicular joint (ACJ) separations using an all-endoscopic double cerclage endobutton technique compared to an arthroscopic-assisted single bundle endobutton technique. The secondary aim was to analyze the complication, failure and revision rate of both procedures. MATERIAL AND METHODS: All patients with acute ACJ separations Rockwood IIIB and V who were operated on using an all-endoscopic double-cerclage technique (2019-2022) or an arthroscopic-assisted single bundle technique (2017-2019) were included...

Background: Concomitant glenohumeral pathologies may be present in patients with acromioclavicular joint (ACJ) dislocations. This study aims to record and compare the prevalence and treatment of CGP in cases with acute and chronic ACJ dislocations. Methods: This retrospective cross-sectional binational, bicentric study included patients that underwent arthroscopically assisted stabilization for acute (group A) and chronic (group C) ACJ dislocations. Intraoperatively, CGPs and eventual treatments (debridement and reconstructive measures) were recorded...

BACKGROUND: The use of total shoulder arthroplasty is continuing to rise with its expanding indications. For patients with chronic conditions, such as glenohumeral arthritis and rotator cuff arthropathy, nonoperative treatment is typically done prior to arthroplasty and often includes corticosteroid injections. Recent studies in the shoulder arthroplasty literature as well as applied from the hip and knee literature have focused on the risk of periprosthetic infection. Literature is lacking as to whether the judicious use of corticosteroids in the year prior to arthroplasty influences patient reported outcomes...

Acromioclavicular ganglion cysts are uncommon, with only a limited number of cases reported in the medical literature. This case report presents a unique instance of an acromioclavicular ganglion cyst in an 81-year-old male patient, outlining the clinical presentation, diagnostic approach, and successful surgical management. The purpose of this report is to contribute to the existing body of knowledge on this rare condition and highlight the importance of accurate diagnosis and appropriate intervention.

BACKGROUND: Shoulder instability is a complex impairment and identifying biomarkers which differentiate subgroups is challenging. There is limited fundamental movement and muscle activity data for identifying different mechanisms for shoulder instability in children and adolescents which may inform subgrouping and treatment allocation. HYPOTHESIS: Children and adolescents with shoulder instability (irrespective of etiology) have differences in their movement and muscle activity profiles compared to age- and sex-matched controls (two-tailed)...

Metastatic calcinosis cutis is a rare consequence of end-stage renal disease (ESRD), which occurs due to elevated levels of serum phosphorus and abnormal phosphate and calcium metabolism, leading to the precipitation and deposition of calcium in the cutaneous and subcutaneous tissues. This paper reports the case of a 33-year-old male with ESRD and a six-year history of hemodialysis treatment who presented with multiple areas of gradually enlarging, lobulated calcified soft tissue masses observed bilaterally at the level of the acromioclavicular joint and superomedial aspect of the right thigh, extensively involving the perineal region and the right superior anterior chest wall...

INTRODUCTION: This study delves into the management of acromion fractures and acromioclavicular (AC) joint dislocations-orthopedic injuries with significant implications for shoulder function. Despite their infrequency, these injuries present challenges due to potential persistent pain and functional limitations. Current treatment strategies span from conservative measures to surgical interventions, yet there exists a notable gap in comprehensive data on specific surgical approaches. PRESENTATION OF CASE: We present a compelling case involving a 38-year-old male athlete who sought medical attention following a motor vehicle accident due to severe right shoulder pain...

PURPOSE: The most common cause of shoulder pain originating from the acromioclavicular (AC) joint is osteoarthritis, causing pain and disability. Operative Management of AC arthritis includes arthroscopic distal clavicle resection (DCR) and open clavicle resection. This study was conducted to evaluate the outcomes of isolated rotator cuff repair with conservative treatment of ACJ arthritis versus the combined resection of the distal clavicle with the repair of a rotator cuff tear, in cases with acromioclavicular arthritis...

PURPOSE: To compare the clinical efficacy of arthroscopic TightRope loop titanium button and clavicular hook plate in the treatment of acromioclavicular joint (ACJ) dislocation of Rockwood III/IV.

This article describes updated treatment strategies for AC separation, including type III AC separation which is known most controversial. Finally, we present a proposed treatment algorithm that can aid in the treatment of AC separation from the most updated evidence...

Acromioclavicular (AC) joint dislocations are not uncommon injuries. High-grade dislocations can be managed by arthroscopic as well as open techniques, but the most important thing is to address both vertical and horizontal stability. The purpose of this study is to evaluate the functional outcome of a cost effective double figure of eight technique of stabilizing both coracoclavicular and acromioclavicular ligaments in acute high-grade disruption (Type IIIB -VI) using fibre tape. This study was performed at our tertiary care centre from 2017 to 2020 after appropriate IRB approval and patient consent...

BACKGROUND: There are few clinical and radiographic studies of coracoclavicular (CC) ligament reconstruction in chronic acromioclavicular (AC) joint dislocation. Additionally, reported AC joint reduction rates vary. HYPOTHESIS: Arthroscopically assisted double-bundle semitendinosus tendon autografts with CC and AC ligament reconstruction for AC joint reconstruction provide AC joint stability and improved function at the final visit. METHODS: In this retrospective study of prospectively collected data, 21 patients surgically treated for chronic AC joint dislocation (Rockwood III-V) were assessed clinically and radiographically preoperatively, and at day 1, 3 months, 12 months, and at a final visit (> 24 months) postoperatively...
