Impact of Flexor Hallucis Longus Retrotalar Pulley Release on First Ray Joint Pressures in Functional Hallux Limitus: A Cadaveric Study
Listen to this summary
This cadaveric study aimed to investigate the biomechanical effects of functional hallux limitus (FHLim) on first metatarsophalangeal joint (MTP1) mobility and pressures, as well as the impact of sectioning the retrotalar pulley of the flexor hallucis longus tendon. The findings revealed that releasing the pulley significantly improved MTP1 dorsiflexion and reduced joint pressures, indicating that pulley impingement contributes to the biomechanical constraints seen in FHLim. This supports the rationale for considering retrotalar pulley release as a surgical intervention for patients with functional hallux limitus.
