Ligament Scaphoid-Cuboid Interosseous

The scaphoid-cuboid ligament is one of the most common ligaments in the human body. It connects the navicular bone of the foot with the cuboid bone of the leg. This ligament plays an important role in maintaining ankle stability and preventing foot dislocation.

The scaphoid-cuboid ligament consists of dense fibrous tissue that connects the scaphoid and cuboid bones. It has the shape of a triangle, the base of which faces the front surface of the foot, and the apex faces the back surface of the lower leg. The ligament consists of two parts: lateral and medial.

The lateral portion of the ligament begins at the lateral edge of the scaphoid and runs along the medial edge of the cuboid. The medial part of the ligament begins on the medial edge of the scaphoid bone, runs along the lateral edge of the cuboid bone and ends on the back of the leg at the ankle joint.

The main function of the navicular and cuboid interosseous ligaments is to support the ankle joints and prevent foot dislocations. When walking and running, the ligament helps keep the foot in the correct position and prevents it from moving. In addition, the ligament is involved in the formation of the structure of the ankle joint, ensuring its stability and strength.

However, if the scaphoid and cuboid interosseous ligaments are damaged, it can lead to various diseases and health problems. For example, when a ligament is torn, ankle instability or foot dislocation may occur, leading to pain and limited mobility. Also, damage to the ligament can lead to disruption of the muscles and ligaments of the ankle joint.

The ligament between the ulna and radius is called the scaphoid (os scaphoideum). It has the shape of a triangular plate of two layers of fiber or hyaline cartilage (starting from 15–16 years) on the back of the forearm, in a triangular notch between the recess of the elbow joint, the radial and ulnar fossae. At a young age, in the lower half of the ligament there are two sections of hyalinized tissue, the so-called grooves - the crest (crista scapheus) and the fossa (fossa scaphi), facilitating the sliding of the radial head of the biceps brachii muscle forward along the middle crack to the inner surface and keeping it from falling forward . The suture of this ligament is damaged by a lateral contusion of the olecranon. When the scaphoid bone is ruptured with displacement of the fragment, the latter can move into the joint cavity and cause deforming arthrosis and bursitis of the elbow joint.
