1. Ninety-two patients with cerebral palsy and 134 fractures were studied during the past ten years at Sonoma State Hospital, Eldridge, California.
2. One hundred thirty-one of the 134 fractures united.
3. Pre-existent contracture of contiguous joints was the factor most consistently associated with fracture, a finding which provides yet another reason for prevention and early correction of contractures.
4. Closed treatment, modified according to the individual patient's needs, is most efficacious.
