Research could lead to better postoperative care for patients who need shoulder arthroplasty revisions

The most common bacterial infection to occur after revision shoulder arthroplasty surgery can be diagnosed more accurately by considering how quickly samples of the microbe grow in hospital labs and the level of bacteria that grows, a study partly performed at UT Southwestern shows.
