Outcomes and Complications of SCFE Surgery

Objective: Slipped capital femoral epiphysis (SCFE) is a common hip disorder affecting children and adolescents. There is much debate concerning best treatment with regards to adverse outcomes, specifically avascular necrosis (AVN). This study analyzed the rates of adverse outcomes after the surgical treatment of SCFEs. It examined risk factors which may lead to the development adverse outcomes. This research will aid clinical decision-making, helping determine optimal surgical treatment of SCFEs and adding to external datasets of SCFE treatment. Methods: This was a retrospective review of patient health records at a level 2 pediatric trauma hospital. The study included all SCFE procedures performed at the hospital from 2005-2018. Data collected included age, gender, BMI, surgical fixation and complications. Descriptive statistics included frequency (percent) used for categorical variables and mean (range) for continuous variables. Results: A total of 222 total cases were reviewed. In situ pinning (ISP) was performed in 203 cases, ISP with hip capsule decompression in 13, and the modified Dunn in 6. Avascular necrosis occurred in 3.4% of ISP cases, 7.7% of ISP with hip capsule decompression, and 66.7% of modified Dunn cases
