Final answer:
The talocrural joint, also known as the ankle joint, results in the greatest loss of motion with arthrodesis.
Step-by-step explanation:
The hindfoot joint that results in the greatest loss of motion with arthrodesis is the talocrural joint, also known as the ankle joint. This joint is a uniaxial joint that only allows for dorsiflexion (bringing the top of the foot toward the anterior leg) or plantar flexion (bringing the foot away from the leg). Arthrodesis of the ankle joint limits its range of motion, resulting in a significant loss of movement in the hindfoot.
