Prediction of Development of Scapular Notching Based on Glenosphere Positioning, Scapular Morphology, and Simulated Impingement-free Motion Using Three-dimensional Computed Tomography Analysis

The hypothesis is that computer simulated bony impingement of the bone surrounding the
spherical glenoid implant (the glenosphere) along the scapular neck on three-dimensional
(3-D) computed tomography (CT) imaging analysis is predictive of the location of clinical
scapular notching that develops following reverse total shoulder arthroplasty (TSA).

The Specific Aims are:

- Determine the relationship between lateral glenoid offset and the development of
scapular notching following reverse TSA

- Determine the ability of 3-D preoperative planning tools to define areas of scapular
bony impingement on kinematic simulated shoulder range of motion that predict the
development of scapular notching

- Compare the precision and accuracy of plain radiographs (2-D) versus CT (3-D) for
measurement of scapular notching and postoperative implant position following reverse
TSA (2-D versus 3-D)

- Determine the implant and anatomic factors that best correlate with clinical outcome
following reverse TSA by retrospective analysis

Inclusion Criteria:

- All patients having undergone reverse TSA at the Cleveland Clinic with a high quality
preoperative CT of the operative shoulder and a minimum of two years out from surgery

Exclusion Criteria:

- All patients having undergone reverse TSA at the Cleveland Clinic with no
preoperative CT or a low quality preoperative CT of the operative shoulder and/or
less than two years from surgery
