Abstract Background This study evaluated the clinical and radiological results of a new transosseous suture-button fixation technique for anterior glenoid fractures. Methods From March 2017 to May 2021, 23 patients with fractures were treated technique. Demographic data, active shoulder function, several scores after minimum 6 months. Fracture reduction button placement assessed via computed to...

BACKGROUND Persistent muscle imbalance and soft-tissue contractures can lead to progressive glenohumeral joint dysplasia in patients with brachial plexus birth palsy. The objective of the present investigation was to determine the effects of tendon transfers and open glenohumeral reduction on shoulder function and dysplasia in patients with preexisting joint deformity secondary to brachial plex...

osteochondritis dissecans (ocd) is a common joint disorder in knee, ankle and elbow, however it can be rarely found in glenohumeral joint. in this study, we report an asymptomatic case of humeral head ocd, which was detected incidentally following a trauma. x-rays showed an area of lucency around an oval bony fragment measuring about 1 cm on the superior aspect of the humeral head. however, the...

BACKGROUND The in vivo stabilizing role of the long head of the biceps tendon (LHB) is poorly understood. While cadaveric studies report that the loaded LHB constrains translations in all directions, clinical data suggest that there is no clinically demonstrable alteration in glenohumeral position after LHB tenodesis or tenotomy. The purpose of this study was to investigate potential alteration...

BACKGROUND Acromial morphology has previously been defined as a risk factor for some shoulder pathologies. Yet, study results are inconclusive and not all major shoulder diseases have been sufficiently investigated. Thus, the aim of the present study was to analyze predictive value of three radiological parameters including the critical shoulder angle, acromion index, and lateral acromion angle...

The shoulder (glenohumeral) joint has the greatest range of motion of all human joints; as a result, it is particularly vulnerable to dislocation and injury. The ability to accurately measure dynamic in-vivo joint kinematics in 6-Degrees-of-Freedom (6-DOF) (translations and rotations) and subsequently quantify articular cartilage contact patterns of that joint has been and remains a difficult b...

Our aim in this prospective study was to evaluate the outcome of total shoulder replacement in the treatment of young and middle-aged active patients with primary glenohumeral osteoarthritis. We reviewed 21 patients (21 shoulders) with a mean age of 55 years (37 to 60). The mean follow-up was seven years (5 to 9). The same anatomical, third-generation, cemented implant had been used in all pati...

Fractures of the proximal humerus can lead to malalignment of the humeral head, necrosis and post-traumatic osteoarthritis. In such cases surface replacement might be a promising option. A total of 28 shoulders with glenohumeral arthritis subsequent to a fracture underwent surface replacement arthroplasty of the humeral head in patients with a mean age of 60 years (35 to 83). On the basis of th...

Ensuring glenohumeral stability during repetitive lifting tasks is a key factor to reduce the risk of shoulder injuries. Nevertheless, the literature reveals some lack concerning the assessment of the muscles that ensure glenohumeral stability during specific lifting tasks. Therefore, the purpose of this study was to assess the stabilization function of shoulder muscles during a lifting task. K...

The purpose of this study was to better understand how lower body kinematics relate to peak glenohumeral compressive force and develop a regression model accounting for variability in peak glenohumeral compressive force. Data were collected for 34 pitchers. Average peak glenohumeral compressive force was 1.72% ± 33% body weight (1334.9 N ± 257.5). Correlation coefficients revealed 5 kinematic v...
