The anterior ligament is a thin and lax membranewliich passes from the anterior margin of the lower end ofthe tibia to the upper aspect of the head of the it is a cushion of fat which rests in the hollow ofthe neck of the astragalus. The posterior ligament is fixed to the tibia and astra-galus near their articular surfaces. Its fibres are weak, andrun chiefly inwards, radiating from the external malleolustipwards to thj tibia and downwards to the astragalus. The synovial cavity of the ankle-joint extends upwards for about a quarter of aninch into the lower tibio-fibular articulation. On the outer side of the entrance tothis recess the synovial membrane forms a small fold containing fat, which occupies.
