Sectioning the plantar fascia. Effect on first metatarsophalangeal joint motion.

A study on the effect of sectioning the plantar fascia on the range of motion at the first metatarsophalangeal joint is presented. Dorsiflexion and plantarflexion range-of-motion data from 18 patients who had no first metatarsophalangeal joint pathology and had undergone an in-step plantar fasciotomy for recalcitrant plantar fasciitis were analyzed. The average increase in dorsiflexion of the first metatarsophalangeal joint after plantar fascia release was 9.8 degrees, which represented a statistically significant increase using a paired t-test. Thus release of the plantar fascia can be considered a potential adjunct to hallux limitus surgery.
