Every month, JBJS publishes a Specialty Update—a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in 13 subspecialties. Click here for a collection of all OrthoBuzz Specialty Update summaries.
This month, Derek Kelly, MD, co-author of the February 21, 2018 Specialty Update on Pediatric Orthopaedics, selected the most clinically compelling findings from among the more than 50 studies summarized in the Specialty Update.
—An analysis of pediatric femoral shaft fractures before and after the publication of clinical practice guidelines1 revealed a significant increase in the use of interlocked intramedullary nails in patients younger than 11 years of age, and an increase in surgical management for patients younger than 5 years of age. Considerable variability among level-I pediatric trauma centers highlights the need for further outcome studies to facilitate updating of existing guidelines.
—A prospective cohort study of pain and opioid use among patients following posterior spinal fusion for adolescent idiopathic scoliosis found that increased age, male sex, greater BMI, and preoperative pain levels were associated with increased opioid use. Findings like these may help guide clinicians in opioid dispensing practices that minimize the problem of leftover medication.
—Two stratification/scoring systems may aid in the early prediction of musculoskeletal infection severity and promote efficient allocation of hospital resources. A 3-tiered stratification system described by Mignemi et al.2 correlated with markers of inflammatory response and hospital outcomes. Athey et al.3 validated a severity-of-illness score and then modified it for patients with acute hematogenous osteomyelitis.
—A study of closed reduction for developmental dysplasia of the hip4 revealed that 91% of 87 hips achieved stable closed reduction. Of those, 91% remained stable at the 1-year follow-up. Osteonecrosis occurred in 25% of cases, but it was not associated with the presence of an ossific nucleus, a history of femoral-head reducibility, or age at closed reduction.
—Regardless of obesity status, serum leptin levels increase the odds of slipped capital femoral epiphysis (SCFE), according to a recent study. Researchers reached that conclusion after comparing serum leptin levels in 40 patients with SCFE with levels in 30 BMI-matched controls.
