Bursitis could be explained as an inflammation of the bursa that is a sac filled with fluid adjacent to the joints that acts like a cushion for the joint.
A bursa is a sac that is filled with lubricating fluid situated between tissues like muscles, tendons, skin and bone that lessens irritation and friction between the tissues. The bursa causes pain in the hip when subjected to continual trauma resulting in swelling and inflammation. This could strongly affect athletes such as runners, footballers and soccer players who frequently put the entire weight of their body on their hips.
The largest bursa of the body is known as iliopsoas bursa which is located between the front side of the joint of the hip and the iliopsoas muscle i.e. a hip flexor. Iliopsoas bursa reduces friction between the iliopsoas muscle and thigh bone. The inflammation of iliopsoas bursa is called as iliopsoas bursitis, also referred to Iliopectineal bursitis. However, sometimes this condition may also be assumed as hip joint arthritis or iliopsoas tendinitis due to the similarity of symptoms. Iliopsoas bursitis often occurs due to trauma and overuse which involves hip flexion such as weight lifting and squatting resulting in imbalance or tightness of iliopsoas muscle, but this can be treated through strengthening and stretching exercises.
Iliopsoas bursitis is caused due to an overuse injury which results from repetitive rubbing of the iliopsoas tendon. Iliopsoas bursitis is most common in sports, which involve repetitive activities such as swimming and running.
