Bursitis is a condition characterized by inflammation of the bursae, which are tiny, fluid-filled sacs that cushion the various bones, tendons, and muscles near a joint.
Musculoskeletal injuries are any injuries causing damage to bone, cartilage, muscles, ligaments, tendons, nerves and related structures. They can occur in any area of your musculoskeletal system such as the neck, back, hips, knees, shoulders, or elbows.
Tendons are powerful fibrous cords which connect muscle to bone. When you overstretch a tendon, it can rupture (tear) completely or partially. This rupturing of the tendon due to overstretching is known as a tendon injury. You typically feel a snap or popping sensation when you rupture your tendon followed by a sharp pain which is likely to affect your mobility and muscle function. Surgery is often regarded as the best treatment.
Sprains and strains are injuries affecting the muscles and ligaments. A sprain is an injury or tear of one or more ligaments that commonly occurs at the wrist, knee, ankle or thumb. A strain is an injury or tears to the muscle. Strains occur commonly in the back and legs.
Joint instability occurs when the surrounding soft tissue structures of a joint fail to stabilize, resulting in a dislocation. A joint is an articulation (junction) between 2 or more bones in the body. Muscles, tendons, ligaments, cartilage, and other soft tissue structures hold the joints in position. Any damage to these soft tissue structures either by external forces such as trauma, or an underlying condition like osteoarthritis, can cause joint instability.
