Bursitis
Causes & Risk Factors
The various causes and risk factors for bursitis include:
Trauma: A traumatic injury in an accident
or a fall could lead to inflammatory bursitis resulting in widening
of the blood vessels thus allowing proteins and extra cellular fluids
into the bursae. This could lead to more swelling of bursae.
Prolonged Pressure: Prolonged pressure
on the tip of an elbow can cause bursitis.
Infection: Bacterial infection to the
bursa after an injury or an insect bite can cause bursitis (5).
Certain locations in the body are affected due to repetitive
motion related certain activities. These locations include:
-
Shoulder: An injury to the
rotator cuff, the muscles and the tendons that connect the
upper arm bone to the shoulder blade due to repetitive overhead
arm activities could cause bursitis.
-
Elbow: Repetitive or prolonged
movement and excessive pressure on elbow by pushing a vacuum
cleaner back and forth, throwing a baseball and swinging
a tennis racket could cause bursitis or tendonitis of the
elbow or shoulder.
-
Buttocks: Continuous sitting
on a hard surface may lead to bursitis of the hip.
-
Hip or Trochanteric Bursitis:
Arthritis or a hip injury and prolonged standing or sitting
often causes bursitis of hip.
- Knee or Goose foot Bursitis or Anserine Bursitis:
Repetitive kneeling, exerting pressure on knees and sharp
blow to knee may cause inflammation to the bursae around the
kneecap leading to bursitis of the knee.
- Ankle: Use of improper footwear, prolonged
walking and sports such as ice skating may cause inflammation
of the bursae in the ankle (6).

Risk Factors Include:
-
Overuse or Repetitive use: Overuse
or repetitive action such as running, stair climbing, bicycling
or standing for prolonged periods can lead to bursitis.
-
Disease: Various diseases such
as arthritis, thyroid disease and diabetes may cause bursitis.
-
Leg-length inequality: When a leg
is shorter than the other by an inch or more it affects walking
and could lead irritation of hip bursa (hip bursitis).
-
Previous Surgery: A surgery around
the hip or prosthetic implants in the hip can irritate the bursae
causing bursitis.
-
Bone spurs or calcium deposits:
Bone spur or calcium deposits can develop within the tendons that
attach to the trochanter causing irritation and inflammation to
the bursa.
-
Crystal deposits: Uric acid, a
normal byproduct of daily metabolism may be deposited as crystals
in joints causing bursitis (7).
