Patients with severe cerebral palsy (CP) are susceptible to bone fractures due to low bone mineral density, deformity from contracture and developmental disability. We experienced a 12-year-old spastic CP female who sustained recurrent fracture of the right femur. The first episode occurred when she had been moved passively by another child in residential care. She underwent operative treatment with plate fixation, but seventeen days after operation, spasticity of legs aggravated and refracture happened at the fixation site. She underwent re-operative fixation, but at three days after the second operation, she sustained another fracture at the top of the plate, for which she underwent the third operation. She was then referred to our department for scissoring patterns of the lower extremities. We performed bilateral obturator nerve block which relieved patient's spasticity. We think that her recurrent fracture may be related with ignored risk factor of refracture such as uncontrolled spasticity. (J Korean Acad Rehab Med 2010; 34: 587-590)
