Do liposomal bupivacaine infiltration and interscalene nerve block provide similar pain relief after total shoulder arthroplasty: a systematic review and meta-analysis.

Controversy still exists regarding the efficiency and safety of liposomal bupivacaine (LB) vs interscalene nerve block (INB) for pain management after total shoulder arthroplasty (TSA). The aim of the present meta-analysis was to perform a relatively credible and overall assessment to compare the efficiency and safety of LB-based infiltration vs INB for pain management after TSA.
