RESUMO
BACKGROUND: From 1999 to 2011, studies demonstrated an increasing trend toward surgical management of adolescent clavicle fractures. The purpose of this study was to examine more recent trends of surgical management of closed clavicle fractures in adolescent patients over the past decade. METHODS: A retrospective cohort study was conducted using the PearlDiver database. Patients with clavicle fractures from 2011 to 2021 were identified and stratified by age, sex, and year of their fracture. Categorical variables were compared with a chi square test, and continuous variables were compared with the Welch t test or Mann-Whitney U test. RESULTS: Overall, there was a significant increase in the percentage of patients surgically treated by open reduction and internal fixation from 2016 to 2021 compared with 2011 to 2015 (8.58% vs. 7.34%, P < 0.001). When stratified by age, both the 10 to 14-year group (3.80% vs. 3.10%, P < 0.001) and the 15 to 18-year group (15.41% vs. 12.84%, P < 0.001) demonstrated significant increases in the percentage of patients surgically treated. CONCLUSION: Despite increasing literature demonstrating high revision surgery rates for surgical treatment of adolescent clavicle fractures with no difference in functional outcomes, this study demonstrated a notable increase in the rate of surgical treatment of adolescent clavicle fractures from 2011 to 2021 in the United States.

PURPOSE: Higher pedicle screw density posterior spinal fusion (PSF) constructs have not been shown to result in improved curve correction in Lenke 1 and 5 adolescent idiopathic scoliosis (AIS) but do increase cost. The purpose of this study questioned whether higher screw density constructs improved curve correction and maintenance of correction in Lenke 2 AIS. Secondary goals were to identify predictive factors for correction and postoperative magnitude of curves in Lenke 2 AIS. METHODS: We identified patients 11 to 17 years old who underwent primary PSF for Lenke 2 AIS between 2007 and 2017 who had minimum follow-up of 2 years. Demographic and radiographic data were collected to perform regression and elimination analysis. RESULTS: Thirty patients (21 females, 9 males) were analyzed. Average age and SD at time of surgery was 14.0 ± 1.8 years (range, 11-17 years), and median follow-up was 2.8 years (IQR 2.1-4.0 years). Implant density did not predict final postoperative curve magnitude. Predictors of final postoperative curve magnitude were sex and preoperative curve magnitude. Predictors of percentage of correction of major curve were sex and age at the time of surgery. Predictors of final postoperative thoracic kyphosis were sex and percent flexibility preop. Females had lower final postoperative major curve magnitude, a higher percent curve correction, and lower postoperative thoracic kyphosis. CONCLUSIONS: Increased implant density is not predictive of postoperative curve magnitude in Lenke 2 AIS. Predictors of postoperative curve magnitude are sex and preoperative curve magnitude. LEVEL OF EVIDENCE: Level III, retrospective observational.
