More About Bursitis

Bursitis is inflammation of a bursa. A bursa is a closed, fluid-filled sac that works as a cushion and gliding surface to reduce friction between tissues of the body. The major bursae (this is the plural of bursa) are located next to the tendons near the large joints, such as in the shoulders, elbows, hips, and knees.

Shoulder Bursitis

Bursitis is usually a temporary condition. It may limit motion, but generally does not cause deformity.

Bursitis can happen in any bursa in the body, but there are some common types of bursitis, including:

  • Retromalleolar tendon bursitis. This type of bursitis is also called Albert disease. It’s caused by things like injury, disease, or shoes with rigid back support. These put extra strain on the lower part of the Achilles tendon. This attaches the calf muscle to the back of the heel. This can lead to inflammation of the bursa located where the tendon attaches to the heel.
  • Posterior Achilles tendon bursitis. This type of bursitis, also called Haglund deformity, is in the bursa located between the skin of the heel and the Achilles tendon. This attaches the calf muscles to the heel. It is aggravated by a type of walking that presses the soft heel tissue into the hard back support of a shoe.
  • Hip bursitis. Also called trochanteric bursitis, hip bursitis is often the result of injury, overuse, spinal abnormalities, arthritis, or surgery. This type of bursitis is more common in women and middle-aged and older people.
  • Elbow bursitis. Elbow bursitis is caused by the inflammation of the bursa located between the skin and bones of the elbow (the olecranon bursa). Elbow bursitis can be caused by injury or constant pressure on the elbow (for example, when leaning on a hard surface).
  • Knee bursitis. Bursitis in the knee is also called goosefoot bursitis or Pes Anserine bursitis. The Pes Anserine bursa is located between the shin bone and the three tendons of the hamstring muscles, on the inside of the knee. This type of bursitis may be caused by lack of stretching before exercise, tight hamstring muscles, being overweight, arthritis, or out-turning of the knee or lower leg.
  • Kneecap bursitis. Also called prepatellar bursitis, this type of bursitis is common in people who are on their knees a lot, such as carpet layers and plumbers.

The most common causes of bursitis are injury or overuse. Infection may also cause it.

Bursitis is also associated with other problems. These include arthritis, gout, tendonitis, diabetes, and thyroid disease.

The following are the most common symptoms of bursitis. However, each person may experience symptoms differently.

  • Pain
  • Localized tenderness
  • Limited motion
  • Swelling and redness if the inflamed bursa is close to the surface of the skin

Chronic bursitis may involve repeated attacks of pain, swelling, and tenderness. These may lead to the deterioration of muscles and a limited range of motion in the affected joint.

The symptoms of bursitis may resemble other medical conditions or problems. Always see a healthcare provider for a diagnosis.
