Hip Injuries & Conditions

A bursa is a small, fluid-filled sac that cushions and reduces friction between bones and soft tissues such as muscles or tendons. Bursitis develops when a bursa becomes irritated and inflamed.

The hip has two bursae that can commonly become inflamed, usually because of an injury or repetitive movements such as running.

A hip dislocation happens when the top of the thigh bone (femur) is forced out of the hip socket. Significant force, such as a car accident or a fall from a great height, can cause a hip dislocation.

Even partial dislocations can result in serious injury to cartilage that can ultimately require surgery. A dislocated hip is an emergency that requires immediate medical attention.

Also known as femoroacetabular impingement (FAI), hip impingement develops when an abnormality in the ball or socket causes pinching or grinding between these two bones. Over time, hip impingement can cause damage to cartilage in the hip, leading to osteoarthritis if left untreated.

If conservative treatments such as physical therapy don’t help, you may need surgery to repair the abnormality and prevent further damage.

Snapping hip syndrome causes a snapping sensation or a popping sound when you extend your leg, such as when stretching, running or standing up after sitting. The snapping or popping happens when a muscle or tendon catches as it moves over bones in the hip.

Snapping hip syndrome usually occurs in athletes and dancers and can result from overuse or an injury. The condition usually doesn’t cause pain, but it can sometimes lead to bursitis.

A sprain is a stretched or torn ligament, and a strain is a stretched or torn muscle or tendon. Sprains and strains can result from overuse, falls, sudden twists, poorly fitting footwear or forceful impacts such as tackles or other contact during sports.

Hip flexors are muscles at the front of the hip that help you lift your leg or move it forward, such as for walking, running or kicking. A strain is a common hip flexor injury.
