ABSTRACT
Introduction: Varus malunion of the proximal femur following internal fixation may result in persistent hip pain, limb length discrepancy, gait disturbance, and functional limitation. Valgus subtrochanteric osteotomy is a recognized corrective procedure that restores the neck–shaft angle, improves biomechanics of the hip joint, and relieves symptoms. This case highlights the role of valgus subtrochanteric osteotomy as a salvage procedure for symptomatic varus hip malunion after internal fixation in adolescent.
Case Presentation: A 17-year-old female presented with persistent hip pain and a noticeable deformity of the left hip six months after undergoing open reduction and internal fixation in early 2025. The patient complained that the operated hip felt bent and different compared to the contralateral side. Clinical examination demonstrated varus deformity of the proximal femur associated with functional limitation. Radiographic evaluation confirmed varus malunion. The patient subsequently underwent valgus subtrochanteric osteotomy to correct the deformity.
Following surgical correction, the patient experienced significant functional improvement. At follow-up, the patient was able to walk long distances with only mild discomfort in the left knee. Limb length was equal bilaterally. The patient was able to climb stairs and sit for prolonged periods without significant limitation, although maximal squatting remained restricted. Overall, hip alignment and functional capacity improved compared with the preoperative condition.
Conclusion: Valgus subtrochanteric osteotomy can effectively correct deformity and improve functional outcomes in adolescents with symptomatic varus hip malunion following internal fixation. This case highlights the role of corrective osteotomy in restoring hip alignment and functional mobility in young patients
