HYPOTHESIS Scapular cortical thickness has not been fully characterized from the perspective of determining optimal screw placement for securing the glenoid base plate in reverse shoulder arthroplasty. MATERIALS AND METHODS Twelve fresh frozen cadaveric scapulae underwent high resolution CT scans with 3-dimensional reconstructions and wall thickness(More)
Biodegradable anchors were designed to provide secure fixation while allowing for later resorption and replacement by host tissue. First-generation implants degraded relatively rapidly and caused foreign-body reactions, synovitis, fragmentation, and osteolysis. Newer implants have similar complications. It is not known if the primary cause of the osteolysis(More)
We conducted a study to evaluate the congruency of fit of current scapular plate designs. Three-dimensional image-processing and -analysis software, and computed tomography scans of 12 cadaveric scapulae were used to generate 3 measurements: mean distance from plate to bone, maximum distance, and percentage of plate surface within 2 mm of bone. These(More)
