Outline of Final Research Achievements

Reverse total shoulder arthroplasty (RTSA) has been used to treat severe complex shoulder problems as a surgical alternative to standard total shoulder arthroplasty (TSA). Soft tissue tension is thought to be an important factor in the clinical performance of reverse total shoulder arthroplasty but there have been no reports quantifying these forces intraoperatively. We have developed a strain gauges instrumented glenosphere to measure shoulder joint forces intraoperatively. Calibrations of the sensor showed approximately errors of 20% for forces. Finite element analyses showed that the current design has a plenty of stiffness. The sensor was used to confirm a feasibility of joint force measurements in a single cadaver shoulder specimen.
