Subtrochanteric fractures after bilateral per cutaneous central femoral screwing, including preventive contralateral screwing in the treatment of instable slipped capital femoral epiphysis, are uncommon. We report the case of an obese boy aged 9 years and 4 months referred to the hospital for the treatment of high-risk unstable left proximal slipped capital femoral epiphysis. An in situ screwing was performed to obtain an epiphysiodesis on the left side. We carried out a contralateral preventive screwing. Six days after the operation, a fall from a height caused a bilateral subtrochanteric fracture along the epiphysiodesis screw channels. The report of this case makes it possible to balance the interest of contralateral preventive screwing in relation to the risk of bilateral subtrochanteric femoral fracture which is seldom described in the literature and is a serious complication in the case of poor compliance following in situ screwing to treat slipped capital femoral epiphysis. In addition, this observation reports for the first time a tip using a LCP® Large Fragment Locking Plate to treat bilateral proximal femur fracture.
