Study: Using Machine Learning to Predict 30-day Mortality after Hip Fracture
A study published in the Nov. 15 issue of the Journal of the AAOS ® reported that a neural networks machine learning model successfully predicted 30-day mortality following hip fracture. The National Surgical Quality Improvement Program database was queried, and 19,835 patients with hip fracture between 2016 and 2017 were identified. Thirty-day mortality was 5.3 percent. Of the three models developed, use of an artificial neural network was associated with the highest predictive ability, followed by logistic regression and naïve Bayes models.

Study: Physical Therapy Reduces Risk of Long-term Opioid Use after Knee Replacement
A study published online in JAMA Network Open found that physical therapy (PT) interventions may reduce risk of long-term opioid use after total knee replacement. In total, 67,322 patients were retrospectively evaluated, including 38,408 opioid-naïve patients. Receipt of preoperative PT was associated with lower odds of long-term opioid use regardless of previous opioid use history. Six or more PT sessions were associated with lower odds of long-term use compared with five or fewer sessions. Initiation of PT at ≥31 days postoperatively was associated with greater odds of long-term use compared with patients who initiated PT within 30 days.

| Study Compares Shoulder Arthroplasty Outcomes in Older Patients with Glenohumeral Arthritis
Total shoulder arthroplasty (TSA) led to superior outcomes compared with reverse TSA (RTSA) in patients aged older than 70 years with glenohumeral arthritis, according to a study published online in the Journal of Shoulder and Elbow Surgery. The researchers used the New Zealand Joint Registry to compare all cases of TSA, RTSA, and revision RTSA for failed TSA. Oxford Shoulder Scores were significantly higher for TSA compared with RTSA at both six months and five years postoperatively. Revision rates were similar between TSA and RTSA. Revision RTSA demonstrated worse outcomes than with primary RTSA.

| Study: Sex Differences in Total Ankle Replacement or Ankle Arthrodesis Outcomes
A retrospective study published online in the Journal of Bone & Joint Surgery found comparable outcomes between men and women who underwent total ankle replacement or ankle arthrodesis for end-stage ankle arthritis. In total, 872 patients were assessed (replacement, n = 629; arthrodesis, n = 243). Minimum average follow-up was four years. The authors noted similar magnitudes of postoperative improvement and wrote that small differences in pain and functional outcomes between sexes disappeared when controlling for confounding variables.

| Study: Injury Patterns in Occupational and Nonoccupational Equestrians
A study published online in Injury assessed differences in injuries between occupational and nonoccupational equestrians. A national database was queried, and 3,911 horse-related injuries were assessed. The most common injury mechanism was falling from the horse. One-third of cases required surgery. Occupational injuries more often affected upper extremities in working age, minority males. Nonoccupational injuries were more common among women across different age groups and were more likely to be head injuries. Helmet use was higher in occupational and nonoccupational sports and nonoccupational recreation activities and was found to decrease risk of severe head injury.

New Carl L. Nelson Award Supports the Advancement of Women in Orthopaedics
The University of California, San Francisco (UCSF) Department of Orthopaedic Surgery received the inaugural Carl L. Nelson, MD, Award for the Advancement of Women in Orthopaedics from the University of Arkansas for Medical Sciences Department of Orthopaedic Surgery. The award recognizes academic orthopaedic surgery departments across the country that have distinguished themselves through their outstanding commitment to achieving diversity, equity, and inclusion of women in orthopaedic medicine. At UCSF, the team uses a multifaceted approach, including unconscious bias training, a holistic review approach to the residency selection process, formalized mentorship programs, outreach initiatives, and professional development.
