RESUMO
OBJECTIVE: To present interdisciplinary practical guidance for the assessment and treatment of spastic equinovarus foot after stroke. RESULTS: Clinical examination and diagnostic nerve block with anaesthetics determine the relative role of the factors leading to spastic equinovarus foot after stroke: calf spasticity, triceps surae - Achilles tendon complex shortening and dorsiflexor muscles weakness and/or imbalance. Diagnostic nerve block is a mandatory step in determining the cause(s) of, and the most appropriate treatment(s) for, spastic equinovarus foot. Based on interdisciplinary discussion, and according to a patient-oriented goal approach, a medical and/or surgical treatment plan is proposed in association with a rehabilitation programme. Spasticity is treated with botulinum toxin or phenol-alcohol chemodenervation and neurotomy, shortening is treated by stretching and muscle-tendon lengthening, and weakness is treated by ankle-foot orthosis, functional electrical stimulation and tendon transfer. These treatments are frequently combined. CONCLUSION: Based on 20 years of interdisciplinary expertise of management of the spastic foot, guidance was established to clarify a complex problem in order to help clinicians treat spastic equinovarus foot. This work should be the first step in a more global international consensus.

Diagnostic tibial nerve block with anesthetics is a common and safe procedure for the management of the spastic equinovarus foot. Side effects have been rarely reported. We present the case of a hemiplegic patient with a spastic equinovarus foot who presented with an avulsion fracture of the calcaneum at the insertion of the Achilles tendon consecutive to a diagnostic tibial nerve block with anesthetic agents. Although rare, such a complication should be considered when the Achilles tendon is shortened and when the patient is suspected of bone osteoporosis or dystrophy.
