Abstract

BACKGROUND AND PURPOSE: Part 1:

To describe the profile of a typical patient diagnosed with glenohumeral osteoarthritis (OA) and identify predictors of total shoulder arthroplasty (TSA).

Part 2:

To identify outcomes after undergoing a TSA due to glenohumeral OA.

METHODS: Part 1:

A retrospective chart review was conducted of 127 patients with a diagnosis of glenohumeral OA from January 2011 to December 2013. Demographic data was collected.

Part 2:

From the original sample, a convenience sample of 22 patients was selected who were at least one year post-TSA. Consent was obtained to perform a post-surgical functional evaluation in their homes or in the clinic based on patient preference. The measures obtained were strength and range of motion (ROM), as well as the subjective reports of the Simple Shoulder Test (SST) and the Shoulder Pain and Disability Index (SPADI).

RESULTS: Part 1:

Of the 127 patients, average age was 70, and 55.9% were male. Surgical shoulder was the right shoulder in 52.8% of the subjects, left shoulder in 36.2% of the subjects, and bilateral shoulders in 10.2% of the subjects. The greatest predictor of undergoing a TSA was pain at rest (7.2).

Part 2:

There was no difference in ROM of shoulder flexion, abduction, internal rotation, and external rotation between surgical and non-surgical shoulders. Strength following a TSA was weaker in shoulder flexion and abduction, equal in rotation, and stronger in grip strength compared to the non-surgical shoulder. Average post-op pain was 1.1 compared to 6.2 pre-op pain which was statistically significant. There was a strong correlation between the SPADI and SST.

CONCLUSION:

The most significant indicator for a TSA is pre-op pain at rest. Patients can expect significantly decreased pain, functional ROM and strength, and improved function following a TSA. Both SPADI and SST are effective outcome measures to assess shoulder pain and function.
