Market resilience of orthopaedic hip/knee arthroplasty sales during COVID-19.
The coronavirus 2019 (COVID-19) pandemic led to a marked decrease in elective surgical volume and orthopaedic device sales. The aim of this paper was to quantify this decrease and the related financial impact on the largest hip/knee arthroplasty companies by: (1) tracking individual hip/knee company valuations; (2) calculating aggregate changes in overall hip/knee arthroplasty market valuations; and (3) quantifying quarterly hip/knee revenues relative to prior years. ⋯ Similar to the overall market and healthcare sector, the top five hip/knee arthroplasty companies have recovered from their COVID market lows. Our results reveal that the valuations of hip/knee companies remained robust during COVID, even as revenues fell, likely due to strong investor confidence in the industry outlook and the greater overall healthcare system utilization.

Review Meta AnalysisEffectiveness of lumbar braces after lumbar surgery: a systematic review and meta-analysis.
To systematically analyze the effectiveness of lumbar braces in patients after lumbar spine surgery. ⋯ Whether or not the use of lumbar braces after lumbar fixation has a negligible impact on clinical outcomes was studied. Subsequent studies could further demonstrate whether the use of lumbar braces after lumbar surgery could reduce the incidence of surgical site infections.

Meta AnalysisRoutine pretransfusion testing before primary total hip or knee arthroplasty are an expensive and wasteful routine. Systematic review and meta-analysis.
The excessive routine ordering of pretransfusion tests (blood typing, screening, and cross-matching) for surgical cases incurs significant unnecessary costs and places an undue burden on transfusion services. This study aims to systematically review the literature regarding the necessity of routine pretransfusion tests before total hip arthroplasty (THA) or total knee arthroplasty (TKA) and summarize their outcomes. ⋯ Our study suggests that routine pre-transfusion testing for all patients undergoing primary THA or TKA may be unnecessary. We propose limiting pretransfusion test orders to patients with preoperative hemoglobin levels below 12 g/dl in unilateral primary TKA or THA. This targeted approach can result in significant cost savings for healthcare systems and transfusion services by reducing the over-ordering of pretransfusion tests in these surgical procedures.

ReviewHip-spine relationship: clinical evidence and biomechanical issues.
The hip-spine relationship is a critical consideration in total hip arthroplasty (THA) procedures. While THA is generally successful in patient, complications such as instability and dislocation can arise. These issues are significantly influenced by the alignment of implant components and the overall balance of the spine and pelvis, known as spinopelvic balance. ⋯ For these reasons, over the years, computer modelling and simulation techniques have been developed to support clinicians in the different steps of surgery. The aim of the current review is to present current knowledge on hip-spine relationship to serve as a common platform of discussion among clinicians and engineers. The offered overview aims to update the reader on the main critical aspects of the issue, from both a theoretical and practical perspective, and to be a valuable introductory tool for those approaching this problem for the first time.

Analysis of complications in 97 periprosthetic Vancouver B2 fractures treated either by internal fixation or revision arthroplasty.
The treatment of Vancouver B2 periprosthetic fractures after hip arthroplasty is still a matter of debate. Revision Arthroplasty (RA) was long thought to be the treatment of choice, however several recent papers suggested that Open Reduction and Internal Fixation (ORIF) is a viable option for selected B2 fractures. Complication rates of 14-26% have been reported following surgical treatment of B2 fractures. No significant difference between RA and ORIF in the complication rates nor in the functional outcome was observed. ⋯ ORIF can be used to revise cemented and non-cemented shafts in more than half of Vancouver B2 fractures with no difference in complication rates when compared to RA. A periprosthetic fracture around the hip has a 21-28% risk of a re-operation after revision surgery with infection and re-fracture after a new fall being the most frequent cause of re-operation.
