Tendoachilles tenodesis to the fibula: a retrospective study.

Tendoachilles tenodesis to the fibula was performed in postpolio patients to improve their gait. The charts of 48 patients with 52 tenodeses were reviewed. The mean follow-up was 5.5 years. Gait improved in one-third. When the hindfoot was stabilized, gait improved in 40% of the patients, but when it was not stabilized, only 22% improved their gait. Excessive equinus developed in 18 patients, all of whom were less than age 12 years when operated. We conclude that it is reasonable to use this procedure to improve the gait of postpolio children with flail lower extremity, provided the hindfoot is stabilized.
