Bursae are fluid filled sacs that provide cushion between bones and tendons. Bursitis of the hip occurs when one of the bursae surrounding the hip becomes inflamed. This commonly occurs as a result of overuse or from an injury, although no obvious cause is sometimes not found.
Symptoms of bursitis usually include local pain and tenderness over the inflamed bursa with ambulation or with pressure over the site such as with sleeping on one’s side.
Starting from around the outer part of the hip known as the greater trochanter, the iliotibial band (also known as “ITB” or “IT band”) travels down to the outside part of the knee. This band can become inflamed for several reasons but typically from an overuse injury and hip muscle imbalance. The IT band can also become inflamed and cause pain around the outer part of the knee, causing what’s known at IT band syndrome. This condition can be common particularly in runners.
Treatment options include non-steroidal anti-inflammatories (NSAIDs) or other analgesic medications and physical therapy for local modalities, stretching and strengthening. US guided corticosteroid injections to the hip bursa can be considered in persistent cases for persistent cases. In certain instances, where the bursitis is a result of a tendinopathy or tendon tear, platelet rich plasma (PRP) may be helpful in treating the underlying condition.
