Ligamento colateral medial del carpo - Ligamentum collaterale carpi mediale


In ungulates, the medial collateral ligament extends between the medial styloid process of the radius and the proximal extremity of the medial metacarpal bone. A deep branch is detached to the second carpal bone.

In carnivores, medial collateral ligament is necessarily much weaker allowing for some adduction and abduction. It is divided into a straight and and oblique part:

  • The straight part runs from a tubercle above the radial styloid process to the most medial part or the intermedioradial carpal bone.
  • The oblique part, after leaving the styloid process, runs obliquely to the palmaromedial surface of the intermedioradial carpal bone.

The tendon of the abductor pollicis longus lies between the two parts as it crosses the medial surface of the carpus.
