Abstract
Background: Treatment of SCFE has remained controversial since long time. Slipped capital femoral epiphysis (SCFE) can be treated by a variety of methods with the method of in situ pinning being most commonly used for mild to moderate cases. More recently, the Safe Surgical Hip Dislocation procedure consisting of capital realignment had been popularized as a treatment method for severe cases of SCFE. The purpose of this article is to evaluate the differences between treatment methods in terms of complication rate, and functional outcomes.
Methods: All patients treated for SCFE with in situ fixation or sub capital osteotomy at our institute were included. Preoperative slip degree was measured radiographically and post operative correction was determined using Southwick angle. Clinical outcome was measured by clinical examination and evaluation based on Harris hip scoring and HOOS scoring system. 45 patients with 56 slips filled out the questionnaires for Harris hip score and Hip Dysfunction osteoarthritis Outcome Score (HOOS).
Results: Patients with mild to moderate and stable slips operated with in situ pinning and patients with severe, unstable slips operated with sub capital osteotomy by anterior approach at our institute had good scores on HOOS and Harris Hip Scoring system and had good radiological outcome and an acceptable complication rate. In both the groups we had 12.5% of patients with complication. AVN rates of 5.35% (3/56) overall and 11.5% (3/26) in sub capital osteotomy group was found.
Conclusion: In situ pinning and sub capital osteotomy gives good result with low complication rate. Thus in situ pinning is a good method for treatment of stable SCFE and sub capital osteotomy for severe slips.
