Antibiotic-laden Bone Cement during TKA Associated with Increased Risk of PJI in Patients Aged >65 Years


According to a study in the Journal of the AAOS®, the use of commercial antibiotic-laden bone cement (ALBC) for infection prophylaxis in patients aged >65 years for total knee arthroplasty (TKA) was associated with an increased risk of 90-day revision for prosthetic joint infection (PJI). To examine the demographics and early outcomes of ALBC, 251,506 patients from the American Joint Replacement Registry were retrospectively analyzed. Patients undergoing TKA with ALBC were more likely to be Non-Hispanic Black, reside in the South, and have a higher mean BMI. ALBC usage was not associated with 90-day all-cause readmissions.

High Rate of Graft Incorporation after Impaction Bone Grafting for Acetabular Reconstruction in THA


The Journal of Orthopaedic Surgery and Research published a prospective study investigating the outcomes of acetabular reconstruction using impaction bone grafting in patients with acetabular bone deficiency undergoing primary or revision total hip arthroplasty (THA). Clinical outcomes were measured via the Harris Hip Score (HHS) and graft incorporation was evaluated via MRI. Fifty patients were included in the study. The mean HHS increased from 28.8 preoperatively to 76.6 after surgery. Seventy patients achieved complete radiological graft incorporation to host bone, and all remaining patients had partial incorporation.

Study Compares Four versus Six Weeks of Immobilization after Closed Reduction for Displaced Distal Radial Fractures


A randomized controlled trial in the Bone & Joint Journal compared the effect of reducing immobilization from six to four weeks in patients with a displaced distal radial fracture following closed reduction. Forty-nine patients comprised the four-week immobilization group, and 51 were in the six-week group The outcome measurements included the Patient-Rated Wrist Evaluation (PRWE) score, level of pain, and range of motion (ROM). The mean PRWE score was 6.9 and 11.6 in the four- and six-week groups, respectively. There were no significant differences in terms of ROM and level of pain.

Study: Staged Circumferential Lumbar Fusions Associated with Shorter Operative Time


The Spine Journal published a propensity-matched study that compared perioperative complications and outcomes between staged versus single-anesthetic circumferential lumbar fusions (cLFs). In-hospital, 30-day, 90-day, and one-year complications were analyzed and compared between 123 patients undergoing single-anesthetic and 154 patients undergoing staged cLF. Single-anesthetic cLF had longer total surgery time (304 minutes versus 240 minutes) but shorter total postanesthesia care unit total time (133 minutes versus 196 minutes). There was no difference regarding in-hospital, 30-day, 90-day, and one-year complications.

What Risk Factors Are Associated with Displacement Recurrence in Pediatric Patients Undergoing Soft-tissue Release?


A case-control study in the Journal of Pediatric Orthopaedics found the recurrence of migration percentage (MP) >5 percent one-year postoperation to be an early indicator for failure to control MP to <40 percent and reoperation in pediatric patients with spastic hip displacement treated by soft-tissue release (STR). To evaluate the recurrence of hip displacement after STR, 66 patients were analyzed, and multiple logistic regression analysis was used to identify risk factors for recurrence. Patients who had a recurrence of hip displacement (n = 19) were twice as likely to experience treatment failure and require reoperation.
