About

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).

Full description

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

Enrollment: 32 patients

Sex: All

Volunteers: No Healthy Volunteers

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

Trial design

32 participants in 1 patient group

Reverse TSA patients

Description:

Patients having undergone reverse TSA at the Cleveland Clinic with a high quality preoperative CT of the operative shoulder and who are at least 24 months post surgery.
