The ligamentum calcaneonaviculare dorsale, also known as the dorsal calcaneonavicular ligament, is a strong fibrous band that connects the calcaneus (heel bone) to the navicular bone in the foot. It is located on the superior or dorsal aspect of the foot, hence the name.
This ligament plays a crucial role in maintaining the stability and structure of the medial longitudinal arch of the foot. It provides support and reinforcement to the joint between the calcaneus and navicular bones, known as the calcaneocuboid joint. The calcaneonavicular ligament helps to prevent excessive eversion (outward roll) of the foot and maintains the correct alignment of the bones during weight-bearing activities.
Structurally, the ligamentum calcaneonaviculare dorsala consists of dense collagen fibers that are arranged in parallel fashion. These fibers provide the ligament with strength and flexibility, allowing it to withstand forces and maintain stability. Together with other ligaments and tendons in the foot, it helps in the transmission of forces and proper distribution of weight during walking, running, and other activities.
Injuries to the ligamentum calcaneonaviculare dorsala can result from excessive twisting or repetitive stress on the foot, such as in sports that involve sudden direction changes or high-impact activities. If torn or damaged, it can lead to pain and instability in the foot, impacting one's ability to walk and engage in physical activities. Proper diagnosis and treatment, including rest, immobilization, physical therapy, and sometimes surgical intervention, may be necessary for recovery.
