Bursitis is the inflammation of one or more bursae (small sacs) of synovial fluid in the body. The bursae rest at the points where internal functionaries, such as muscles and tendons, slide across bone. Healthy bursae create a smooth, almost frictionless functional gliding surface making normal movement painless. When bursitis occurs, however, movement relying upon the inflamed bursa becomes difficult and painful. Moreover, movement of tendons and muscles over the inflamed bursa aggravates its inflammation, perpetuating the problem. Muscle can also be stiffened.

Bursae- are fluid filled membrane sacs that serve as buffers between tendon and bone, skin and bone or between two bones.  They act as lubrificators to decrease friction.

Causes :

  • repetitive movement and excesive pressure : shoulders, elbows and knees are the most commonly affected
  • Inflammation of the bursae might also be caused by other inflammatory conditions such as rheumatoid arthritis and gout
  • traumatic injuries : the inflammation irritates because the bursa no longer fits in the original small area between the bone and the functionary muscle or tendon. When the bone increases pressure upon the bursa, bursitis results.

Signs :

  • pain due to increased fluid production : as fluid accumulates,pressure builds causing pain
  • swelling
  • decreased ROM ( range of motion )
  • loss of function

Treatment :

– follow the inflammation treatment protocol ( ITP  )   -> u can revise it in the Inflammation topic of my blog

Bursae that are not infected can be treated with rest, ice, elevation, physiotherapyanti-inflammatory drugs and pain medication. Since bursitis is caused by increased friction from the adjacent structures, a compression bandage is not suggested because compression would create more friction around the joint. Advanced massage therapy techniques can also be employed to help with the inflammatory process of bursitis.Bursae that are infected require further investigation and antibiotic therapy. In cases when all conservative treatment fails, surgical therapy may be necessary. In a bursectomy the bursa is cut out either endoscopically or with open surgery. The bursa grows back in place after a couple of weeks but without any inflammatory component.
