PURPOSE To compare diameter-based glenoid bone loss quantification with a true geometric calculation for the area of a circular segment. METHODS By use of Maxima 12.01.0 mathematics modeling software (Macysma, Boston, MA), the diameter-based glenoid bone loss equation (% Bone loss = [Defect width (w)/Inferior glenoid circle diameter (D)] × 100%) was compared with a true geometric calculation ...

BACKGROUND AND PURPOSE Glenoid reconstruction and inverted glenoid re-implantation is strongly advocated in revisions of failed reverse shoulder arthroplasty (RSA). Nevertheless, severe glenoid deficiency may preclude glenoid reconstruction and may dictate less favorable solutions, such as conversion to hemiarthropasty or resection arthropasty. The CAD/CAM shoulder (Stanmore Implants, Elstree, ...

Glenoid hypoplasia, also known as glenoid dysplasia and dysplasia of the scapular neck, is a failure of ossification of the posteroinferior two-thirds of the glenoid. Once thought to be a rare condition, more recent studies have shown that the incidence of glenoid hypoplasia ranges from 18% to 35%. This case report and literature review highlights the typical clinical presentation, the radiolog...

BACKGROUND Current knowledge is lacking concerning the appropriate site of osteochondral allograft harvest to match glenoid shape for the purposes of glenoid resurfacing. This has led to difficulty with adequate restoration of the geometry of the glenoid with currently available techniques. HYPOTHESIS The medial tibial plateau will provide a suitable osteochondral harvest site because of its ...

BACKGROUND Multiple bone-grafting procedures have been described for patients with glenoid bone loss and shoulder instability. The purpose of this study was to investigate the alterations in glenohumeral contact pressure associated with the placement and orientation of Latarjet or iliac crest bone graft augmentation and to compare the amount of glenoid bone reconstruction with two coracoid face...

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...
