Abstract
Purpose: Management of pediatric subtrochanteric femur fractures (SFFs) is difficult. The aim of this study was to evaluate the outcomes of adolescent SFFs treated with adult proximal humeral locking plates (PHLPs).

Materials and Methods: A retrospective analysis of 18 adolescents (11 male, 7 female) with a diagnosis of SFF who underwent internal fixation with a PHLP was conducted. Data regarding injury mechanism, fracture pattern, and time to union were recorded for all patients. In addition, a clinical and functional evaluation of patients was performed using the Harris hip score (HHS), Iowa hip score (IHS), modified Merle d¡¯Aubigne-Postel score(MMAPS), Flynn criteria, and hip range of motion (ROM).

Results: The mean age of the patients was 12.72¡¾2.05 years (range, 10-16 years). Radiological observation was performed for evaluation of five different injury mechanisms and different fracture patterns in patients. The mean postoperative HHS was 92.27¡¾5.61, the mean IHS was 90.88¡¾6.46, and the mean MMAPS was 17.22¡¾0.94. According to the Flynn criteria, excellent results were achieved in 14 cases and satisfactory results were obtained in four cases. Measurements of the patients¡¯ mean hip ROM values were as follows: 17.77¡¾3.52¡£in extension, 115.27¡¾6.74¡£in flexion, 43.05¡¾3.48¡£in abduction, 27.50¡¾4.28¡£in adduction, 42.22¡¾4.60¡£in internal rotation, and 42.22¡¾3.91¡£in external rotation.

Conclusion: Surgery performed on adolescent patients using an adult PHLP showed good, safe results. Therefore, it should be considered as an alternative option.
