Ligaments

Ligaments

1. what are ligaments?

   • bands of strong fibrous tissue
   • hold bone to bone
   • joint tendons to bone and keep tendons into position

2. the position of ligaments

   • "Capsular" ligament
     • around the margin of a joint
   • "collateral" ligament
     • by the side of joints holding bone to bone
   • "Peri-articular" Ligaments
     • Peri=around
       • form part of the fibous layer of joint capsule
   • intra-articular ligaments
     • intra=within
       • within the joint cavity
   • interosseous ligaments
     • connect opposed surfaces of bone together e,g, M2 + M4 to M3
       • they have short fibres that allow little/no movement

3. the function of ligaments

   • Interosseous ligament
     • little/no movement
   • collateral ligament
     • fasten bone to bone with directional movement
   • capsular ligament
     • can wrap around joints and contain fluid
   • annular ligament
   • check ligament
   • suspensory ligament
   • chondro-ungular ligament
   • Palmer intersesamoidian ligaments
