Neuropathic injuries to the lower extremities in children.

Neuropathic injuries of the lower extremities in children due to meningomyelocele, congenital indifference to pain, and peripheral nerve damage were studied in 10 patients. The injuries fell into four categories: (a) fractures of the metaphysis and diaphysis of long bones, (b) epiphyseal separation, (c) Charcot joints, and (d) soft-tissue ulceration. These injuries are often unrecognized; untreated, they can lead to severe disability. For patients with impaired sensation, radiographs should be obtained at any sign of localized soft-tissue swelling, warmth, or hyperemia, especially near a joint. Following diagnosis, immobilization of the limb will lead to prompt healing of fractures and epiphyseal separation.
