The Comprehensive® Shoulder Solutions’ Modular Hybrid Glenoid from Biomet is a revolutionary design for replacement of the glenoid in total shoulder arthroplasty. It provides three outer pegs and three central peg options for surgical implantation. In vitro testing of the Modular Hybrid Glenoid resulted in mean axial pull-out peak loads ranging from 209 to 303 lbf, mean inferior/superior shear ...

OBJECTIVE This article discusses the imaging findings, clinical findings, and conservative chiropractic management of 2 patients with glenoid hypoplasia. CLINICAL FEATURES Conventional radiographs of both patients revealed a hypoplastic glenoid bilaterally. Notch-like defects along with signs of degenerative disease were evident within the lower portion of the glenoid rims bilaterally in 1 pa...

Glenoid morphology has an important impact on outcomes and complication rates after shoulder arthroplasty for primary glenohumeral arthritis. The B2 glenoid, or a biconcave glenoid with posterior humeral head subluxation, in particular has been associated with a poorer outcome with shoulder arthroplasty compared with other glenoid types. A variety of techniques may be used to address the bone d...

BACKGROUND Large glenoid rim defects in patients with traumatic anterior shoulder instability are often regarded as a contraindication for arthroscopic Bankart repair, with a defect of 20% to 27% considered as the critical size. While recurrence of dislocations, male sex, and collision sports were reported to be the significant factors influencing large glenoid defects, the influences of sublux...

Introduction Glenoid prosthesis loosening is a major complication of shoulder arthoplasty, thus highlighting the importance of improving glenoid prostheses longevity [1]. Finite element (FE) stress analyses have been used to assist joint prosthesis designs. Prior FE analyses have employed static or non-linear solutions to compare design variations with respect to stresses in the glenoid bone an...

BACKGROUND Anterior shoulder instability associated with severe glenoid bone loss is rare, and little has been reported on this problem. Recent biomechanical and anatomical studies have suggested guidelines for bony reconstruction of the glenoid. HYPOTHESIS Anatomical glenoid reconstruction will restore stability in shoulders with recurrent anterior instability owing to glenoid bone loss. S...

BACKGROUND Accurate analysis of osseous glenoid morphology is important in treating glenohumeral arthritis and instability. Two-dimensional computed tomography scans are used to evaluate glenoid alignment. Accuracy of this method is dependent on the angle of axial reconstruction in relation to the position of the scapula. The purpose of this study was to investigate the effect of scapular rotat...

Shoulder stability depends on the position of the arm as well as activities of the muscles around the shoulder. The capsulo-ligamentous structures are the main stabilisers with the arm at the end-range of movement, whereas negative intra-articular pressure and concavity-compression effect are the main stabilisers with the arm in the mid-range of movement.There are two types of glenoid bone loss...
