A case of late sequela of infantile hip infection treated by Ilizarov hip reconstruction using monolateral fixator

A 13-year-old female presented with chronic instability of her left hip due to late sequela of infantile hip infection. Instability of hip causes significant problems due to pain, limp, and shortening. Such a case is rare and difficult to treat. We performed a subtrochanteric valgus extension pelvic support osteotomy, along with distal varization and lengthening osteotomy utilizing a monolateral fixator. The patient was clinically and radiologically followed up for 24 months after her operation. The fixator was removed after 12 months once radiological union and adequate lengthening was achieved. Pre- and postoperative assessments were done using the Harris Hip Score, which showed a significant improvement. Long duration of usage of the fixator, knee stiffness, and pin tract infections are a few of the limitations observed.
