Study: Trends in TSA and RTSA Incidence and Complications in the U.S.
An analysis of total shoulder arthroplasty (TSA) and reverse TSA (RTSA) published in the July issue of the Journal of the AAOS: Global Research & Reviews ®, found RTSA is more common in the U.S. Patients were identified via the PearlDiver Mariner database. Surgical complications and revision rates for RTSA were 226 percent and 3.56 percent, respectively, versus 6.36 percent and 2.42 percent for TSA. TSA had higher rates of surgical complications for patients aged ≥50 years compared to RTSA (3.94 percent versus 2.25 percent). Male sex, tobacco use, depression, and obesity were associated with increased risk of complications.

Study Identifies Incidence and Risk Factors of Metachronous PJI
A retrospective study published online in The Journal of Arthroplasty found that periprosthetic joint infection (PJI) at one site may predispose patients to subsequent PJI in other prosthesis. The researchers reviewed 294 patients who were treated for first-time PJI. Ninety-six patients with at least one other prosthetic joint at the time of developing a single PJI were included. Average follow-up was 11.2 years. Overall, 19.79 percent developed metachronous PJI, and the causative pathogen was the same in 63.16 percent of cases. The average time to second PJI was 789.84 days. Systemic inflammatory response syndrome, ≥3 stages of resection arthroplasty, and methicillin-resistant Staphylococcus aureus were risk factors for subsequent PJI.

| Study: Conservative Treatment of Valgus-impacted Hip Fracture in Older Patients
A study published online in Injury assessed incidence and risk factors for failure after conservative treatment of valgus-impacted femoral neck fractures in elderly patients. Fifty-five patients treated between 2009 and 2018 were retrospectively reviewed. The failure rate was 27.3 percent (n = 15). Independent predictors for failure included chronic kidney disease, medial cortex displacement, high posterior tilt, and high retroversion. The cutoff values for retroversion and posterior tilt as predictors for failure were 12.5 degrees and 7.5 degrees, respectively.

| Study: Mid- to Long-term Outcomes after Ankle Sprain in Young Athletes
Compared with young athletes without ankle sprain injury, patients with injury reported persistent pain and symptoms, poor ankle function, reduced sport participation, reduced balance, and increased fear of pain up to 15 years after injury. This retrospective study was published online in Foot & Ankle International. Patient-reported outcomes from 50 patients with time-loss ankle sprains who were followed for a median of eight years were compared to 36 uninjured sex- and sport-matched controls. Compared to the controls, previously injured patients scored lower on all five Foot and Ankle Outcome Score subscales regardless of sex and time since injury.

| Study: What Happened to Elective Spinal Surgeries Canceled Due to COVID-19?
According to a report from a single institution, 36.8 percent of 133 elective spine surgeries canceled due to the COVID-19 pandemic were not rescheduled as of January 2021. This study was published online in The Spine Journal. Of 49 patients who did not reschedule, 2.0 percent had a future surgery date and 8.2 percent required updated exams before rescheduling. Forty percent of non-rescheduled cases were deferred due to COVID-19 concerns and 16.3 percent for medical comorbidities. Three patients cancelled due to symptom improvement, four patients changed to nonsurgical management, and two patients had since deceased.
