Objective: Slipped capital femoral epiphysis (SCFE) or epiphysiolysis is a common pathology that requires urgent surgical intervention. This study aims at evaluating clinical and radiological mid-term results of our patients diagnosed with SCFE and fixed with a single cannulated screw.

Methods: We examined 13 hips of 12 patients treated with SCFE and evaluated mid-term results in our study.

Results: All of our patients were male with a mean age of 11.8 years (range 7-15). The mean slip angle was calculated as 43.20 degrees (range 26-70), and the average length of follow-up was 19 months (range 14-29 months). The average body mass index was 26.8 (range 24.4-29.7), and 11 patients were overweight (91.7%). Concerning ambulation, 7 patients had stable SCFE (58.3%), and 5 had unstable SCFE (41.6%). According to the Southwick classification, the average sliding angle of the patients was 43.2 degrees (range 26-70). Fixation was performed with a single cannulated screw for all patients. No patients were applied screws to the opposite hip for prophylactic purposes. Loss of reduction was not observed in any of our patients who followed up on average for 19 months (range 14 to 29). In radiological follow-ups, SCFE was not observed in the opposite hip of any patient. The postoperative range of motion was normal in all patients. Shortness and limping were not observed in any case.

Conclusion: We suggest that in SCFE cases requiring urgent surgery, the mild reduction can be considered, and subsequent osteosynthesis with a single screw is a sufficient treatment.
