Quadratus plantae muscle

The Quadratus Plantae Muscle is a muscle located in the human foot. It is one of the intrinsic muscles of the foot, meaning it is located entirely within the foot and plays a crucial role in foot movement and stability.

Anatomy

The Quadratus Plantae Muscle originates from the medial and lateral condyles of the heel bone and inserts into the lateral margin of the tendon of the Flexor Digitorum Longus. It is innervated by the lateral plantar nerve.

Function

The primary function of the Quadratus Plantae Muscle is to assist in the flexion of the lateral four toes at the interphalangeal joints. It also aids in stabilizing the toes during walking and running.

Clinical Significance

Damage or injury to the Quadratus Plantae Muscle can result in foot pain and difficulty in toe flexion. It is also implicated in conditions such as plantar fasciitis and flat feet.
