Ms. Mizel et al., Role of the peroneal tendons in the production of the deformed foot with posterior tibial tendon deficiency, FOOT ANKL I, 20(5), 1999, pp. 285-289
Ten patients were identified with traumatic, complete common peroneal nerve
palsy, with no previous foot or ankle surgery or trauma distal to the knee
, who had undergone anterior transfer of the posterior tibial tendon to the
midfoot, Six of these patients had a transfer to the midfoot and four had
a Bridle procedure with tenodesis of half of the posterior tibial tendon to
the peroneus longus tendon. Average follow-up was 74.9 months (range, 18-3
51 months). Ali patients' feet were compared assessing residual muscle stre
ngth, the longitudinal arch, and motion at the ankle, subtalar, and Chopart
's joint. Weightbearing lateral X-rays and Harris mat studies were done on
both feet. In no case was any valgus hindfoot deformity associated with pos
terior tibial tendon rupture found. It seems that the pathologic condition
associated with a posterior tibial tendon deficient foot will not manifest
itself if peroneus brevis function is absent.
