  More info

  Stress shielding of the humeral stem is a known complication in press-fit total shoulder arthroplasty (TSA), but there remain limited data on its prevalence and clinical impact in midterm follow-up. The purpose of this study was to determine the prevalence of humeral stem stress shielding and its impact on functional outcomes at minimum 5-year follow-up in standard length press-fit TSA. The hypothesis was that the presence of stress shielding at minimum 5-year follow-up would not affect functional outcome scores or range of motion (ROM).

  More info

  All-polyethylene glenoid components designed for osseous integration of the central peg can be placed with no graft (NG), autogenous bone graft (ABG), or demineralized bone matrix (DBM). The purpose of this study was to compare osseous integration with these 3 techniques. A randomized controlled trial was performed of 153 total shoulder arthroplasties using a pegged allpolyethylene glenoid component designed for osseous integration. Central peg treatment included NG, ABG, or DBM. The primary outcome was central peg osseous integration defined as bone presence between the central fins 1 year postoperatively. Central osseous integration was observed in 90% of cases treated with ABG, 68% of cases treated with DBM, and 68% of cases treated with NG (P=.022). Postoperative Wirth grading revealed radiolucency around the central peg (grade 1) in 2.4% of cases with ABG, 5.4% of cases with DBM, and 9.8% of cases with NG (P=.134). At short-term follow-up, osseous integration of the central peg of an all-polyethylene glenoid designed for bony growth between the central fins appears to be highest when treating the central peg with ABG compared with leaving the central peg untreated or using DBM.

  The purpose of this study was to compare the functional outcomes and humeral stress shielding of a reverse shoulder arthroplasty (RSA) placed with either cement or press-fit fixation. The hypothesis was that there would be no difference in functional outcomes or stress shielding.

  More info

  Humeral stem length in anatomic total shoulder arthroplasty (TSA) continues to decrease in an attempt to preserve bone. Outcomes following short-stem TSA are not well documented. The purpose was to systematically review and report the outcomes and revisions following short-stem humeral implants for TSA.

  More info

  In shoulder arthroplasty, cerclage fixation techniques are used to stabilize osteotomies, fractures, and allografts. Fixation techniques including cerclage with metal and polymer cables have been described. The purpose of this study was to evaluate suture cerclage fixation of the humeral shaft during shoulder arthroplasty.

  More info

  Distal radius repair is a common orthopedic surgery often performed at outpatient surgical centers. To date, little is known regarding optimal pain control in this setting. In this study, the authors evaluated patients who underwent distal radius open reduction and internal fixation (ORIF) in an outpatient surgery center setting. Comparisons between 2 surgical groups, peripheral nerve block without general anesthesia vs general anesthesia only, were recorded in terms of postoperative length of stay (LOS) in phase I, total LOS, and patient-reported pain level at discharge. The authors identified 80 patients undergoing distal radius ORIF from March to August 2016. A total of 37 (46.3%) patients received general anesthesia only and 43 (53.8%) patients received peripheral nerve block without general anesthesia. Overall, patients in the nerve block only group showed a statistically significant decrease in pain at discharge, as well as decreased phase I and total LOS. Although the power of the data is low relative to the number of distal radius procedures performed every year, there is a trend of better pain control and decreased LOS when using nerve blocks instead of general anesthesia.

  The coronavirus disease 2019 (COVID-19) pandemic has become the dominant health-care issue of this generation and has reached every corner of the health-care delivery spectrum. Our 3 orthopaedic departments enacted a response to the COVID-19 pandemic within our organizations. We discuss our health-care systems' response to the outbreak and offer discussion for the recovery of the orthopaedic service line within large health-care systems.
