Stress fracture of the navicular bone in a patient with cerebral palsy: a case report.

A 14-year-old girl with cerebral palsy (spastic diplegia) underwent examination due to a chief complaint of right foot pain, and was diagnosed with a stress fracture of the central one third of the navicular bone. The fracture was considered to have developed due to repeated loading on the navicular bone as a result of an equinus gait.Therefore, she underwent osteosynthesis and Achilles tendon lengthening to correct the equinus deformity.
