A 15-year-old boy presented with a severe fluctuating foot and ankle dystonia resulting from a basal ganglia insult at the age of 4. This followed an embolic event related to an undiagnosed prolapsed mitral valve. Functionally, the patient was ambulatory with rocker bottom crutches and an ankle-foot orthosis, but there were periods of up to a year when pain and increased dystonic deformity required him to use a wheelchair. A new orthotic was made nearly every month because the orthotist could find no material that would withstand his tone without breaking, yet he could not ambulate without one. Multiple interventions, including biofeedback, contrast baths, stretching and strengthening, oral lioresal (Baclofen), diazepam (Valium), benztropine mesylate (Cogentin), carbidopa-levodopa (Sinemet), carbamazepine (Tegretol), and injections of botulism toxin (BOTOX) were tried, all with minimal effects. Amputation was recommended, based on anatomic and functional considerations. The patient and his family adjusted well to this decision, although not all orthopedists and therapists adjusted easily to the choice. The patient is now functionally independent with a prosthesis and has a normal teenage lifestyle for the first time.
