The prepatellar bursa is a superficial bursa with a thin synovial lining located between the skin and the patella. Normally, it does not communicate with the joint space and contains a minimal amount of fluid; however, inflammation of the prepatellar bursa results in marked increase of fluid within its space.
Pathophysiology: The...

- a type of cyst which results from egress of fluid through a normal communication of a bursa (semimembranosus or medial gastrocnemius bursa) or may be caused by herniation of the synovial membrane through the joint capsule;

Olecranon bursitis is condition in which there is inflammation of the bursa that overlies the olecranon process at the proximal aspect of the ulna. The bursa is located between the ulna and the skin at the posterior tip of the elbow; because of its superficial location, the olecranon bursa is...

Pain at the posterior heel or posterior ankle most commonly is caused by pathology at the posterior calcaneus, the Achilles tendon, or the associated bursae. Two bursae are located just superior to the insertion of the Achilles (calcaneal) tendon. Inflammation of either or both bursae can cause pain at the...

The bursa is what cushions the tendon and thereby helps prevent friction between the tendon and the bone.  Unfortunately, constant rubbing of the tendon over the bone with high amounts of repetitive arm, shoulder, hip, knee and ankle motion can lead to enough friction of the bursa itself to cause...

Bursa and spaces

Bursitis is inflammation of a bursa caused by repetitive use, trauma, infection, or systemic inflammatory disease. Bursae are flattened sacs that serve as a protective buffer between bones and overlapping muscles (deep bursae) or between bones and tendons/skin (superficial bursae). These synovial-lined sacs are filled with minimal amounts of fluid...

Trochanteric bursitis is characterized by painful inflammation of the bursa located just superficial to the greater trochanter of the femur. Patients typically complain of lateral hip pain, although the hip joint itself is not involved. The pain may radiate down the lateral aspect of the thigh.

Bursitis Definition Bursitis is the painful inflammation of the bursa, a padlike sac of fluid found in areas of the musculoskeletal system that are subject to friction, such as joints. Bursae cushion the movement between the bones, tendons, and muscles near the joints. Bursitis is most often caused by repetitive movement performed...

Multiple heredity exostosis is characterized by palpable osseous projections from the cortex of the bone, joint restrictions, and secondary osseous deformities. Deformities that are frequently noted include widening of the proximal femoral metaphysis, bilateral coxa valga, deviation and shortening of the ulna, and forearm shortening. This disorder is autosomal dominant...
