Hallux Limitus and Hallux Rigidus
Decreased range of motion ROM of the big toe (Hallux) joint, or 1st metatarsophalangeal (MTP) joint, due to joint degeneration. Normal ROM at the 1st MTP joint typically ranges between 50-90 degrees dorsiflexion, where the toe is lifted up. Hallux Limitus is a limitation of the Hallux, and the loss of ability to dorsiflex within this normative ROM. Hallux Rigidus is the end stage of joint degeneration where the Hallux begins to fuse to the 1st metatarsal, resulting in under 5-10 degrees ROM, or no motion.
Hallux Limitus and Rigidus are often result from trauma or damage to the 1st MTP earlier in life. Additional causes of Hallux Limitus and Rigidus include:
