Ligament Triangular Left

The right triangular ligament is a ligament located on the anteromedial surface of the tendon of the external oblique muscle in the direction from the lower to the upper third. The triangular internal and external ligaments correspond to the internal and external lateral ligaments. Both internal ligaments are located in the middle between the tendon m. gastrocnemii and the bodies of the 5th lumbar vertebra posteriorly. The corresponding external ligaments are located between the tendons of m. tricipitis brachii post. and anterior to the bodies by the 4th and 5th lumbar vertebrae.

The triangular left ligament or external oblique ligament is absent during embryogenesis and develops only from the 17th week of intrauterine life. During the second year of life, all the main ligaments are formed, and the triangular ligament is in strong connection with the rest of the lateral group ligaments. The thin interosseous ligament of the leg, or malleolar ligament, and the entire fifth ligament of the foot, or risolysis, are present only after the completion of the second period of embryonic development.

There is no attachment point under the saphenous ligament; its tip ends at the inferior part of the scaphoid. Lying anteriorly above the calcaneus, it attaches to the heel bone and is thus supported by the outward rotation of the foot. Half the length of the ligament holds the lateral surface of the tibia, the larger half - the inner surface of the lateral side of the surface of the tibia along its entire length. The upper part of the complex is back
