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. Here is a summary of selected findings cited in the February 17, 2016 Specialty Update on pediatric orthopaedics:
Guidelines and AUCs
–The AAOS updated its clinical practice guidelines on the treatment of pediatric diaphyseal femoral fractures1 and adopted appropriate use criteria (AUC) for pediatric supracondylar humeral fractures with vascular injury.2
–A matched case control study of surgical spinal procedures found that neuromuscular scoliosis, weight for age ≥95th percentile, ASA score of ≥3, and prolonged operative time were associated with a higher risk of surgical site infection.3
–Several groups, including the Scoliosis Research Society and POSNA, endorsed the definition of early-onset scoliosis as “scoliosis with onset less than the age of ten years, regardless of etiology.”4, 5
–A prospective randomized study found that preoperative education and orientation for scoliosis surgery paradoxically increased immediate postoperative anxiety among patients and caregivers, relative to controls who received standard perioperative information.6
–A randomized trial investigating perioperative blood loss and transfusion rates in patients undergoing posterior spinal arthrodesis for adolescent idiopathic scoliosis found that tranexamic acid and epsilon-aminocaproic acid reduced operative blood loss but not transfusion rates when compared with placebo.
–A study of 30 patients with severe stable slipped capital femoral epiphysis found that good or excellent results were achieved over 2.5 years in a higher proportion of those receiving a modified Dunn realignment compared with those treated with in situ fixation. The reoperation rate was greater in the in situ fixation cohort.7
–A prospective study analyzing complications after periacetabular osteotomy for acetabular dysplasia using the modified Clavien-Dindo grading scheme found grade III or IV complications in 5.9% of 205 patients, with a nonsignificant trend associating complications with male sex and obesity.
–A registry-based study found that, compared with matched controls, patients with Legg-Calve-Perthes disease had an elevated hazard ratio of 1.5 for ADHD, 1.3 for depression, and 1.2 for mortality. It remains unclear whether patients with Legg-Calve-Perthes disease would benefit from routine psychiatric screening.8
–A case control study of 822 injured athletes and 368 uninjured athletes found that overuse injuries represented 67.4% of all injuries. The risk of serious overuse injury was two times greater if the weekly hours of sports participation were greater than the athlete’s age in years.9
–A meta-analysis of initial nonoperative treatment compared with operative treatment of ACL tears in children and adolescents noted instability and pathologic laxity in 75% of patients with nonoperative treatment compared with 14% of patients following reconstruction.10
–A review of more than 4,400 supracondylar humeral fractures with isolated anterior interossesous nerve palsies but without sensory nerve injury or dysvasculartity found that postponing treatment for up to 24 hours did not delay neurologic recovery.
–A randomized controlled trial investigating the effectiveness of analgesics during intraossesous pin removal found that acetaminophen and ibuprofen were clinically equivalent to placebo in terms of pain reduction and heart rate.
Foot and Ankle
–A study exploring risk factors for failure of allograft bone after calcaneal lengthening osteotomy found a lower risk of failure with tricortical iliac crest allograft relative to patellar allograft. The risk of radiographic graft failure increased with patient age.11
–A prospective nonrandomized study of symptomatic planovalgus feet comparing subtalar arthroereisis with lateral column lengthening found similar postoperative improvements and complication rates in both groups after one year.12
Musculoskeletal Infection & Neuromuscular Conditions
–A cohort study of 869 children with osteomyelitis, septic arthritis, pyomyositis, or abscess concluded that routinely culturing for anaerobic, fungal, and acid-fast bacterial organisms is not recommended except in patients with a history of penetrating injury, immunocompromise, or failure of primary treatment.
–A prospective study comparing tendon transfers, botulinum toxin injections, and ongoing therapy in children with upper-extremity cerebral palsy found that tendon transfer demonstrated greater improvements than the alternatives in joint positioning during functional tasks and grip and pinch strength.
