In patients with shoulder arthritis, the ability to accurately determine glenoid morphological alterations affects the outcomes of shoulder arthroplasty surgery significantly. This study was conducted to determine whether there is a correlation between
Aims.
During shoulder arthroplasty the native functionality of the diseased shoulder joint is restored, this functionality is strongly dependent upon the native anatomy of the pre-diseased shoulder joint. Therefore, surgeons often use the healthy contralateral
Aims. The objective of this study was to compare simulated range of motion (ROM) for reverse total shoulder arthroplasty (rTSA) with and without adjustment for scapulothoracic orientation in a global reference system. We hypothesized that values for simulated ROM in preoperative planning software with and without adjustment for scapulothoracic orientation would be significantly different. Methods. A statistical shape model of the entire humerus and

Background. Glenoid baseplate fixation for reverse shoulder arthroplasty relies on the presence of sufficient bone stock and quality. Glenoid bone may be deficient in cases of primary erosions or due to bone loss in the setting of revision arthroplasty. In such cases, the best available bone for primary baseplate fixation usually lies within the three columns of the
The purpose of this study is to quantify the distribution of bone density in the scapulae of patients undergoing reverse shoulder arthroplasty (RSA) to guide optimal screw placement. To achieve this aim, we compared bone density in regions around the glenoid that are targeted for screw placement, as well as bone density variations medial to lateral within the glenoid. Specimen included twelve

Summary Statement. We measured scapulothoracic motions during humeral abduction with different humeral rotations in healthy subjects and whole cadaver models and clarified that humeral rotation significantly influenced

Introduction: Facioscapulohumeral muscular dystrophy (FSHD) is the third most common hereditary disease of the muscle after Duchenne and myotonic dystrophy. FSHD consists in an atrophic myopathy with predominant involvement of the face, upper arms, and shoulder muscles. FSHD compromises the muscles of the scapu-lothoracic joint, and usually spares muscles of the scapu-lohumeral joint. Consequently, when the patient tries to abduct or foreword flex the shoulder, the contraction of the relatively preserved scapulo-humeral muscles produces an abnormal rotation of the

Reconstruction of large composite tissue defects with expose tendons, neurovascular structures, joints and bones is difficult and challenging problem. Such difficult situations can be handled in a single stage with free tissue transfer provided microsurgical expertise is available. A review of 12 cases of free
