title: Selective tibial neurotomy in the treatment of spastic equinovarus foot: a 2-year follow-up of three cases.
abstract: OBJECTIVE
  To objectively assess the decrease in spasticity and the improvement in gait after tibial nerve neurotomy performed to treat spastic equinovarus foot.
  
  
  METHODS
  Before-after trial with a 2-yr follow-up. Three hemiplegic patients with spastic equinovarus foot were treated with a selective peripheral neurotomy of the tibial motor nerve branches (soleus, lateral and medial gastrocnemius and tibialis posterior nerves). Evaluation included clinical assessment of spasticity (Ashworth scale), maximal Hoffmann reflex (H(max))/compound muscle action potential (M(max)) ratio measurement, gait analysis, and muscle stiffness evaluation performed before and 2 mos, 1 yr, and 2 yrs after the neurotomy.
  
  
  RESULTS
  Spasticity, muscle stiffness, and H(max)/M(max) ratio decreased after neurotomy. The kinematic (ankle dorsal flexion and knee recurvatum) and kinetic variables (maximum ankle muscle moment and external work) of the gait were permanently improved after neurotomy. Interestingly, kinetic variables seemed to gradually improve with time after the neurotomy.
  
  
  CONCLUSIONS
  Tibial neurotomy is an effective and durable treatment for spastic equinovarus foot.
