Comparison of analgesic efficacy of continuous perineural catheter, liposomal bupivacaine, and dexamethasone as an adjuvant for interscalene block in total shoulder arthroplasty: a triple-blinded randomized controlled trial.

Background: Interscalene catheters (ISC) are considered as the gold standard for perioperative pain control after total shoulder arthroplasty. Liposomal bupivacaine (LB) for interscalene blocks (ISBs) and the addition of dexamethasone to ISBs have both presented as additional options for extended analgesia. We aimed to compare the efficacy of LB to a single-shot ISB (SISB) with added dexamethasone to an ISC.

Anatomic total shoulder arthroplasty for B2 glenoids treated with asymmetric reaming has equivalent survivorship and patient outcomes compared with type A glenoids at a mean 9-year follow-up.

Background: Walch B2 glenoids can present a challenge to shoulder arthroplasty surgeons. Short-term studies have demonstrated that corrective reaming to 10° of retroversion in anatomic total shoulder arthroplasty (aTSA) can result in good outcomes; however, there is little data reporting the long-term outcomes in this cohort. B2 glenoids treated with high-side reaming present a theoretical risk of early glenoid component failure as one may ream into the subchondral bone.

Effect of patient-reported allergies on reverse total shoulder arthroplasty outcomes at over two years follow-up.

Background/aims: Understanding the factors that lead to poor outcomes after reverse total shoulder arthroplasty (rTSA) is important to appropriate patient counseling. While patient-reported allergies (PRAs) have been shown to be associated with poorer outcomes after both TKA and THA, their effect on rTSA outcomes remains unclear. This study investigated the effect of zero, one, and two or more preoperative PRAs on clinical outcomes after rTSA at over two years follow-up in a cohort of fifty-two patients from our institution.

Cemented vs. press-fit humeral stems: a matched cohort analysis at a mean follow-up of 10 years.

Background: Although cementation of humeral stems has long been considered the gold standard for anatomic shoulder arthroplasty (aTSA), cementless, or press-fit, fixation offers a relatively cheaper and less demanding alternative, particularly in the setting of a revision procedure. However, this approach has been accompanied by concerns of implant loosening and high rates of radiolucency. In the present study, we performed a propensity-matched comparison of clinical and patient-reported outcomes between cemented and cementless fixation techniques for aTSA.
