Interscalene nerve block and liposomal bupivacaine have been found to provide adequate pain control following shoulder arthroplasty. We hypothesized that local infiltration of a periarticular cocktail would provide equivalent pain control compared to interscalene nerve block and liposomal bupivacaine. ⋯ A decrease in early postoperative pain and opioid consumption was found with local infiltration of a periarticular cocktail when compared with interscalene nerve block and liposomal bupivacaine after shoulder arthroplasty.Level of evidence: Level II.

Outcomes instruments are used to measure patients' subjective assessment of health status. The Patient-Reported Outcomes Measurement Information System (PROMIS) Global-10 was developed to be a concise yet comprehensive instrument that provides physical and mental health scores and an estimated EuroQol-5 Dimension (EQ-5D) score. ⋯ Level II, study of diagnostic test.

The suprascapular nerve is largely responsible for the majority of the sensory innervation of the acromioclavicular joint. In this anatomical study, we describe, in detail, the anatomy of the sensory innervation of the acromioclavicular joint by the branches of the suprascapular nerve. ⋯ A detailed anatomical description of the sensory innervation of the acromioclavicular joint from suprascapular nerve branches was performed, which can potentially aid in the development of more focused anesthetic blockades and acromioclavicular joint denervation procedures.

High rates of positive Cutibacterium acnes cultures from primary shoulder surgery make positive cultures in the revision surgery setting difficult to interpret. Our goal was to determine concordance between culture and next-generation sequencing techniques for identification of C. acnes from primary shoulder surgery. ⋯ There was limited concordance between culture and next-generation sequencing for C. acnes identification. Further studies are needed to determine the potential for next-generation sequencing as a diagnostic tool.

Shoulder arthroplasty with previous axillary lymph node dissection historically has unsatisfactory outcomes. We analyzed outcomes of primary shoulder arthroplasty in patients with previous axillary lymph node dissection. ⋯ Axillary lymph node dissection is not a contraindication to shoulder arthroplasty. A deltopectoral exposure can be utilized without substantial risk of worsening lymphedema or wound complications. While a superior approach avoids cephalic vein injury, important approach-related complications (deltoid dehiscence and axillary nerve palsy) were observed.Level of evidence: Level IV-case series.
