Patient-Specific Implants in Severe Glenoid Bone Loss
The American Journal of Orthopedics, 2018Complex glenoid bone deformities present the treating surgeon with a complex reconstructive challenge. Although glenoid bone loss can be encountered in the primary setting (degenerative, congenital, post-traumatic), severe glenoid bone loss is encountered in most revision total shoulder arthroplasties.

Radiographic sclerotic contour loss in the identification of glenoid bone loss
Knee Surgery, Sports Traumatology, Arthroscopy, 2014AbstractPurposeQuantification of glenoid bone loss guides surgical management in the setting of anterior shoulder instability. Glenoid defects resulting in ≥20 % articular area loss require bony reconstruction. The objective of this study was to evaluate the utility of sclerotic glenoid contour loss on true anteroposterior radiography in the detection ...

The use of reverse shoulder arthroplasty has steadily expanded to treat increasingly complex shoulder pathology present in severe osteoarthritis, cuff tear arthropathy, and revision shoulder arthroplasty. Glenoid bone loss has long been a challenge faced in both primary and revision shoulder arthroplasty.

CT Compared with Arthroscopy in Quantifying Glenoid Bone Loss
American Journal of Roentgenology, 2007This study investigated the accuracy of CT in determining the presence and severity of glenoid bone loss in patients with unilateral anterior shoulder dislocation.Fifty patients (45 males, five females; mean age, 28.7 years; age range, 14-56 years) with anterior shoulder dislocation underwent shoulder CT examination before arthroscopy (mean time ...

Challenges in Reverse Shoulder Arthroplasty: Addressing Glenoid Bone Loss
Orthopedics, 2016Reverse shoulder arthroplasty (RSA) was designed for the treatment of elderly patients with cuff tear arthropathy. Because of its success, the indications for RSA have expanded beyond cuff tear arthropathy to include acute fractures, fracture sequelae, massive rotator cuff tears, inflammatory arthritis, and revision shoulder arthroplasty ...

The American Journal of Sports Medicine, 2017
Background: The anatomic restoration of glenoid morphology with an implant-free J-shaped iliac crest bone graft offers an alternative to currently widely used glenoid reconstruction techniques. No biomechanical data on the J-bone grafting technique are currently available. Purpose: To evaluate (1) glenohumeral contact patterns, (2) graft fixation under

So far, glenoid implantation still remains a challenge and is technically demanding even for an experienced shoulder surgeon. Each shoulder pathology has its own evolution. In primary glenohumeral osteoarthritis, glenoid involvement and proper morphology vary considerably. Erosion is more posterior and inferior. In rheumatoid arthritis, glenoid erosion

Fixation and durability of a bone-ingrowth component for glenoid bone loss
Journal of Shoulder and Elbow Surgery, 2012Deficient glenoid bone is a reconstructive challenge in shoulder arthroplasty. One solution is an ingrowth anatomic glenoid with column and screw fixation, with or without supplemental bone graft. This study examines the outcome of patients managed in this manner.This type of glenoid component was used in 21 shoulder arthroplasties with central or ...

Glenoid Bone Loss: Etiology, Evaluation, and Classification.
Instructional course lectures, 2020Understanding the location and magnitude of glenoid bone loss is extremely important at the time of both primary and revision shoulder arthroplasty. Specific patterns of glenoid bone loss have been described for primary glenohumeral osteoarthritis, cuff tear arthropathy, inflammatory arthritis, and failed shoulder arthroplasty. Although radiographs are

Ensuring Accurate Component Placement in Glenoid Bone Loss.
Instructional course lectures, 2020Glenoid component malposition has important implications for implant wear and longevity after shoulder arthroplasty. Although not confirmed by long-term clinical studies, multiple biomechanical studies have identified altered wear forces, increased contact pressures, decreased contact area, eccentric loading, and potential for loosening associated with
