Résumé : |
The deltoid and spring ligaments are not separate entities, but rather they form a large confluent ligament, the tibiocalcaneonavicular (TCNL) ligament; as such, they work as one functional unit, each playing its specific role.
Besides maintaining medial ankle stability, the superficial portion of the deltoid ligament plays a significant role in maintaining rotational ankle stability. With loss of deep deltoid ligament, the talus progressively disconnects from the tibia and furthermore, the pivoting of the talus along the medial malleolus will be lost; this leads to a lateral shift of the center of rotation and thus a lateral shift of the articular load. The spring ligament plays a fundamental role in the static stability of longitudinal arch, and it also contributes to medial ankle stability. Reconstruction of all affected structures to restore the stability of the medial ankle joint complex may need the use of tendon grafts or/and internal braces; however, to tenodese the tibionavicular joint may be critical as it blocks physiologic pronation of the hindfoot. |
