Percutaneous Motor Point Block to Tibialis Posterior by Anterior Approach
|
|

Abstract
|
|
|
The action of tibialis posterior muscle is to adduct the forepart of the foot and to aid in inversion and plantar flexion. Hypertonicity of this muscle was well known as a main casue of equinovarus or inversion of the foot and internal rotation
deformity of the ankle. Percutaneous motor point block to tibialis posterior muscle might be a physiatric management for the ankle deformity by hypertonicity of the muscle. The posteromedial approach to the muscle has been used in needle
electrode
insertion of electromyography so far. The safe window for tibialis posterior entry is small and the likelihood of mistakenly sampling the flexor digitorum is high in posteromedial approach widely used, because the tibialis posterior is heavily
overladen
with surrounding muscles and lined by neurovascular bundles. We preferred anterior approach to posteromedial approach.
Percutaneous motor point block to tibialis posterior muscle by anterior approach was done with 7% aqueous solution of phenol in 7 cerebral palsied. We suggest anterior approach to the muscle may be safer, easier, and more effective than the
posteromedial approach.
