First take a look at what makes up the MSD injuries. The soft tissue injuries are sometimes caused by chronic stress place on a joint, or in some instances can be caused by an injury by a single blow. Some basic injuries are the sprain, the strain, contusion, tendinitis or bursitis:
- The strain is the stretching and/or tearing of tendons and muscles.
- The sprain is the stretching and/or tearing of the ligaments, the ligaments are strands that connect the bone to the body. Because connective tissues such as ligaments must withstand a great deal of stress in day to day activities and have a relatively low blood supply, injuries can take a very long time to heal, and sometimes require surgery.
- Contusion is basically a bruise where small blood vessels are broken and blood is trapped beneath the skin.
- Tendinitis is the inflammation of the tendons. Tendons are the structure that connects the muscles to the bone.
- Bursitis is an inflamed bursa (sac) which helps relieve friction in joints.
