The spring ligament, also known as the plantar calcaneonavicular ligament, is a crucial structure in the foot that supports the arch and aids in maintaining stability during movement. Damage or dysfunction of this ligament can lead to flatfoot deformity and impact overall foot mechanics, necessitating proper diagnosis and treatment for optimal foot health.

Spring Ligament

The plantar calcaneonavicular ligament, also known as the spring ligament, is crucial for maintaining the arch of the foot and providing stability during movement. It connects the calcaneus and navicular bones, supporting the head of the talus and playing a significant role in weight distribution across the foot.

The foot arch is a crucial structure in the human foot that provides support, balance, and shock absorption during movement. It consists of three arches: the medial longitudinal arch, the lateral longitudinal arch, and the transverse arch, each playing a specific role in maintaining foot stability and distributing body weight efficiently.

Damage or dysfunction

Flatfoot deformity, also known as pes planus, is a condition where the arches of the foot collapse, leading to the entire sole coming into complete or near-complete contact with the ground. This condition can be asymptomatic or cause pain and discomfort, and it may be congenital or acquired due to factors like injury, arthritis, or obesity.
