Better to Break a Bone Than to Tear a Ligament or Tendon
In physiotherapy we deal with both broken bones and torn ligaments a regular basis. But we noticed that patients tend to protect one more than the other. For example, when playing a sport like football, patients more often than not choose to protect a shin-bone (shin guards) than to wear a knee guard to support our ligament or tendons there. If you had a choice between breaking a bone or tearing a ligament; breaking bone seems like a more painful and dramatic options to choose from. Nevertheless, we really ought to protect our ligaments and tendons also because they are more difficult to heal than a bone, when damaged.
Bones Heal Better Than Ligaments and Tendon
Breaking any of bone, ligament or tendon is a painful thing. We should avoid them as much as possible. But why do bones heal better than ligaments/tendons? The short answer is because bone has plenty of blood supply to it compared to ligament/tendon, which have very little and ligament/tendons are more complex to rebuild.
Plenty of Blood Supply
Having good blood supply or being highly vascularised (has many blood vessels) is important for growth and regeneration. Blood brings with it the building materials that the body needs as well as the energy required to build up its parts. In the case of bone, it is highly vascularised compared to ligaments and tendon, which barely has any. Tip: Next when you are eating chicken wings, take a look the tendons.
More Complex Structures
Bones also heal more quickly is simply because they are less complex to build compared to ligaments and tendon. Designed to take a lot of stress along its lengths, there is a lot of effort required to align the ligament and tendon building materials in a specific way.
So the next time you think about protecting or preventing broken bones, give a thought to your other ligaments and tendons in your joints.
