Abstract
Flexor hallucis longus tendon release for surgical treatment of functional hallux limitus-associated conditions is described. This release is obtained by arthroscopic correction of the tendon's blockage, which is located at the retrotalar pulley. The procedure restores the ability for dorsiflexion of the first toe in ankle dorsiflexion (positive stretch test result). Such movement was not possible before, causing a modified gait pattern and affecting the biomechanics of the foot and leg. This explains why the procedure creates favorable changes concerning foot dynamics by restoration not only of the normal tendon glide but also of the normal mobility of the subtalar joint.
