Document Summary

Mostly damage to passive tissue (ligament or capsule) Can involve damage to muscle, tendon and joint. Tears capsule mostly, sometimes plantar plate (bottom of foot) Cause: hyper-extension: 2 sesamoid bones rest under head of mt; embedded in tendon, flexors of big toe affected (halluces longus + brevis, during hyper-extension, can disrupt plantar plate/joint capsule, tendons of fhl/fhb, fracture sesamoids. Talocrural joint (ankle) is dorsiflexed whole toe is hyperextended. Axial load pushed through heel while foot is dorsiflexed. When a football player gets into 3 point stance and needs to explode forward, their toes are fixed on the ground and force their foot into extension. Contraction of flexor halluces muscles is enough to cause damage. (less common turf toe moi) Disrupt structures on dorsal aspect of mtp as opposed to plantar fascia. Footwear allows hyperextension of toes: synthetic playing surfaces. With synthetic turf, foot stays fixed on ground, more friction therefore more injuries.
