BILATERAL NONUNITED FEMORAL-NECK FRACTURE IN A CHILD WITH OSTEOPETROSIS

We report a case of osteopetrosis with bilateral nonunited femoral nec k and coxa vara in a 7-year-old boy. There was a history of traumatic transcervical left femoral neck fracture unsuccessfully treated by int ernal fixation. We performed a bilateral subtrochanteric valgus osteot omy. K-Wire fixation failed on the right side due to hardness of the b ane. Finally, internal fixation with an angular plate after predrillin g of the femoral neck offered stability. Bone union was achieved on bo th sides, resulting in full recovery of normal physical activity.
