Stabilization of a proximal femoral physeal fracture in a filly by use of cancellous bone screws.

A Salter-Harris type-II fracture of the proximal portion of the right femur in a 2-month-old filly was reduced and stabilized with three 6.5-mm-diameter, 100-mm-long cancellous bone screws through a dorsal approach to the right coxofemoral joint. The screws were removed after 11 months because the filly became lame in the affected limb. The surgical wounds dehisced despite preventive measures, most likely because of tightness of skin in the coxal region. Seven years after the original injury, the horse could perform vigorous paddock exercise without any disability. Early internal fixation of proximal femoral physeal fractures in foals can provide a good long-term prognosis.
