Orthopedic aspects of congenital insensitivity to pain.
In an 11-year-old girl with congenital insensitivity to pain, diagnosis depended on three diagnostic features: pain sensation absent from birth; entire body affected; all other sensory modalities and deep tendon reflexes present. The cause of this disease is unknown. Other diseases to be considered when insensitivity to pain is present are diabetes, lues, and syringomyelia. Less common neurologic diseases are congenital sensory neuropathy with or without anhidrosis, familial dysautonomia (Riley-Day syndrome), and sensory radicular neuropathy. The three orthopedic manifestations of congenital insensitivity to pain are recurrent fractures, neuropathic (Charcot's) joints, and osteomyelitis. Management is based on proper appreciation of the disease. Prevention of complications is important. Treatment of fractures and osteomyelitis is straightforward. However, the treatment of neuropathic joints demands caution and is done best nonsurgically.
