Tendons powered by the muscles from which they originate are responsible for movement of the limbs. Tendon physiology is complex but ultimately depends on gliding and balance in the tensions of all the tendons around the joints. Tendon injury or disease process can compromise this resulting in the loss of function. Tendons that are completely disrupted from injury or disease process need to be repaired timeously. The rehabilitation in terms of movement and splintage is important in realizing the full restoration of function.
Tendons traverse through multiple pulley systems to achieve mechanical advantage. Pulley reconstruction, division or preservation is an important aspect of tendon surgery. Eg. triggering of a digit is easily solved by division of a pulley in the hand so that gliding of the affected tendon can be restored.
