title: The use of open phenol blocks to the motor branches of the tibial nerve in adult acquired spasticity.
abstract: Spasticity of the posterior calf muscles often occurs following head injury or spinal cord injury. If left untreated, equinovarus contractures of the foot and ankle may occur in a relatively short time period. This paper retrospectively reviews nine patients with either closed head injury (six patients) or spinal cord injury (three patients) who underwent open phenol injections into the motor branches of the tibial nerve in 16 limbs. Spasticity was decreased in all patients. No significant equinus contractures had occurred at final follow-up. Five of the patients were subsequently able to ambulate. One patient had recurrence of spasticity requiring a second surgical procedure (split anterior tibial tendon transfer), and two patients had significant toe clawing at final follow-up. Open phenol injections to the motor branches of the tibial nerve safely and effectively prevent foot and ankle contractures following spinal cord injury or head injury.
