PURPOSE: Coracoid morphology has been related to coracoid impingement mainly resulting in anterior shoulder pain aggravated by forward flexion and internal rotation. However, the coracoid process morphology can also affect the inclination of the coracoacromial ligament and subsequently the subacromial space in the same way that acromial slope does. The purpose of this study was to evaluate the influence of the coracoid body-glenoid surface, coracoid tip-glenoid surface, and coracoid body-coracoid tip angles (coracoid inclination angles) on rotator cuff tears (RCTs)...

BACKGROUND: Understanding the mechanisms of shoulder impingement created by clinical tests is crucial to accurately evaluate the condition. The objective of this study was to relate mechanisms of subacromial and coracoid impingement occurring in positions of the shoulder during clinical examination, in quantitative and qualitative terms. METHODS: A 1.0T open magnetic resonance imaging system was used in 18 female and 19 male subjects, to determine the distances between the humeral head and the acromion or coracoid, and contact with the rotator cuff (RC)...

INTRODUCTION: Arthroscopy has become a major diagnostic tool and treatment option for shoulder pathology. However rare, respiratory complications such as a pneumothorax have been reported in patients undergoing shoulder arthroscopy. Surgery - as well as anesthesiology-related factors and respiratory comorbidity have been hypothesized to intervene in the onset of respiratory complications. CASE REPORT: We report the case of a 42-year-old male patient who underwent an arthroscopy of the left shoulder...

BACKGROUND: Frozen shoulder is not an uncommon disorder, and steroid injection into the glenohumeral (GH) joint is one of the most well-known approaches for the frozen shoulder. However, their results have been varied with beneficial effects or no additional advantage. With the understanding about the pathological changes taking place in frozen shoulder and the biomechanics involved, we wanted to evaluate the short- and long-term efficacy of steroid injection by a novel three-site (NTS) injection technique and compare it with the single-site injection (SSI)...

BACKGROUND: Long-term results regarding tear progression, arthropathy, and clinical scores of unrepaired rotator cuff tears are largely unknown. This study investigated whether the condition of the glenohumeral joint and rotator cuff had deteriorated at a minimum of 20 years after an acromioplasty without cuff repair and assessed the clinical results. METHODS: A retrospective analysis was conducted of a consecutive series of patients treated between 1989 and 1993 with acromioplasty without cuff repair due to subacromial pain and cuff tear...

PURPOSE: A clavicle hook plate is a simple and effective method for treating acromioclavicular dislocation and distal clavicle fractures. However, subacromial osteolysis and peri-implant fractures are complicated for surgeons to manage. This study uses finite element analysis (FEA) to investigate the post-implantation biomechanics of clavicle hook plates with different hook angles. METHODS: This FEA study constructed a model with a clavicle, acromion, clavicle hook plate, and screws to simulate the implantation of clavicle hook plates at different hook angles (90°, 95°, 100°, 105°, and 110°) for treating acromioclavicular joint dislocations...

Down-sloped or hooked acromion morphologies may cause bony encroachment on the soft tissues of the subacromial space, predisposing to shoulder impingement syndrome. Of the latter, a hooked or Type III acromion (T3A) has also been linked to rotator cuff (RC) pathology. However, as bony acromial impingement is typically thought to occur over the age of 40, its occurrence in younger shoulder athletes presenting with shoulder pain, impingement and RC pathology may be overlooked. This case serves to illustrate the occurrence of T3A in a younger shoulder athlete, and the importance of early imaging in achieving diagnostic accuracy...

PURPOSE: We attempted to investigate whether ultrasound (US)-guided intraarticular or subacromial bursa corticosteroid injections can potentially influence the severity of depression and anxiety in patients with chronic stroke with hemiplegic shoulder pain (HSP). METHODS: Thirty patients with chronic stroke with HSP received US-guided corticosteroid injections. Numeric rating scale (NRS) scores, passive shoulder range of motion (ROM), Beck Depression Inventory (BDI) scores, and Spielberger State-Trait Anxiety Inventory (STAI) scores were evaluated before the injection, and one and two months after the injection...

Mechanical subacromial rotator cuff compression is one theoretical mechanism in the pathogenesis of rotator cuff disease. However, the relationship between shoulder kinematics and mechanical subacromial rotator cuff compression across the range of humeral elevation motion is not well understood. The purpose of this study was to investigate the effect of humeral elevation on subacromial compression risk of the supraspinatus during a simulated functional reaching task. Three-dimensional anatomical models were reconstructed from shoulder magnetic resonance images acquired from 20 subjects (10 asymptomatic, 10 symptomatic)...

The subacromial bursa (SAB) is the main bursa of the shoulder. It facilitates normal movement and is also commonly involved in shoulder disorders. Other shoulder bursae have been described but their anatomy has not been well studied. Anatomical variation of shoulder bursae has been suggested and this has implications for clinical practice. This article reviews current knowledge of the normal anatomy of the SAB and related shoulder bursae. A systematic review of the English and German literature was conducted using databases and a hand search of reference lists focusing on the clinical anatomy of the SAB, coracobrachial and subcoracoid bursae and subtendinous bursa of subscapularis...
