Hip deformity and dislocation in spina bifida.

A group of 118 patients with spina bifida treated between 1960 and 1988 was reviewed with a focus on the problem of hip deformity and dislocation. Deformity can be avoided by physical therapy and correct posture. Hip dislocation often occurs in cases of high or mid-lumbar lesions; at lower levels subluxation is more common. In choosing appropriate treatment, the most important consideration is the patient's true functional potential. If the patient is either not ambulatory or severely impaired, his or her condition will not be exacerbated by a dislocated hip.
