Cage implantation decompresses neural elements, stabilizes segments, and promotes fusion, with sagittal balance influenced by cage size, geometry, and position. This retrospective study compared the effects of lumbar interbody cages with 10° and 15° lordotic angles on global and segmental lordosis in patients undergoing transforaminal lumbar interbody fusion (TLIF). Data from 215 patients who underwent 259 TLIF procedures between 2018 and 2022 were analyzed.

Article Synopsis
  • Nocturnal knee pain and poor sleep quality are common concerns for patients undergoing knee arthroplasty, and this study aimed to assess their prevalence and factors involved.
  • The study involved 111 patients with evaluations of sleep quality and pain at multiple time points, revealing that 54% of patients had poor sleep quality before and after surgery, and 39% experienced nocturnal pain preoperatively, dropping to 3% one year post-surgery.
  • Higher nighttime pain was linked to greater overall pain intensity and increased use of painkillers; patients who had unicompartmental arthroplasty reported significantly less nocturnal pain than those who had total knee arthroplasty.

Objective: This study aimed to assess whether a specific adjustable compression garment (ACG) system (Coolflex Standard Calf and Coolflex Standard Foot; Sigvaris Inc.) promotes self-care in patients with chronic leg oedema. Secondary aims were to assess the effectiveness of this ACG in reducing oedema, improving patient reported outcomes, and determining the patients' degree of satisfaction with the handling of the wrap.

This study analyzed the migration of a calcar-guided short stem to determine the course of very early migration, as well as evaluated the effect of an additional calcium phosphate (CP) coating on a titanium plasma spray (TPS) coating, which has not been analyzed previously. Sixty patients were enrolled in this study and were treated with the A2 calcar-guided short stem. The implant coating was randomized with either the TPS or an additional CP coating, and radiostereometric analysis was performed with the baseline measurement before initial weight-bearing, along with follow-up examinations at 1 week, 6 weeks, 3 months, and 6 months.

Background: Patients with preoperative anemia have a higher risk of requiring blood transfusion after major orthopedic surgery due to increased blood loss and closer transfusion thresholds. Various patient blood management (PBM) policies aim to reduce transfusion rates. This observational study aimed to investigate blood loss and evaluate the effectiveness of an adjusted surgical PBM protocol in patients with anemic chronic disease (ACD) undergoing elective total knee arthroplasty (TKA).
