The use of the PROSTALAC for the treatment of infection following shoulder arthroplasty is beneficial. Infection was initially eradicated in twenty-three (82%) of twenty-eight patients, more than half of our patients had mild or no pain, and 43% of patients declined a second-stage procedure because of acceptable function and pain relief. Conversely, five of twenty-eight patients had severe pain and five patients had persistent infection requiring additional surgery. The use of the reverse total shoulder arthroplasty did not appear to improve outcomes.
The present study supports the use of ultrasound-guided interscalene block by trained anesthesiologists for well-screened patients undergoing shoulder arthroscopy, given the high rate of patient satisfaction and the low rate of adverse events.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
