Which term describes decreased ROM at the base of the big toe joint?

• A. hallux valgus
• B. hallux rigidus
• C. hallux limitus
• D. metatarsalgia

Answer: (C)

The term describes limited movement at the first metatarsophalangeal joint, the joint at the base of the big toe. When that joint’s motion is reduced, especially its dorsiflexion during push-off, the condition is hallux limitus. It indicates a restriction in range, not a complete loss of motion. Hallux rigidus is the more advanced stage where motion is severely limited or lost. Hallux valgus is a deformity with the toe deviating toward the other toes, typically with a bunion, and metatarsalgia refers to pain under the ball of the foot rather than a ROM issue at the joint.
