Symptoms

The main symptom of ischiofemoral impingement syndrome is hip pain. At first, the pain from this condition will be mild, but it gets worse and worse over time as the rubbing of the bones causes more damage, inflammation.

Ischiofemoral impingement syndrome can feel a lot like a pulled hamstring, but the pain is usually more local to the buttocks. Sometimes, you can feel pain in the hip or groin as well.

When to See a Doctor

If you notice a lot of pain in the hips, buttocks, or groin that does not go away, you should see your healthcare provider to find out the cause of your pain.

Some of the symptoms of ischiofemoral impingement syndrome are the same as the symptoms of other serious conditions like muscle tears, tendon tears, or fractures. Your healthcare provider can do a physical examination and tests that can diagnose or rule out ischiofemoral impingement as well as these other conditions.

Causes

An ischiofemoral impingement happens when there is contact between the top of the thighbone (the femur) and the hip bone (the ischium). Usually, these two bones touch in a way that lets them move without pain, but trauma, overuse, and surgery can damage the bone.

Sometimes, this damage causes a piece of extra bone, called a bone spur, to grow on the hip or femur. This bone spur can start to rub on the femur and hip bones, causing more damage and making the condition worse.

Diagnosis and Tests

To diagnose an ischiofemoral impingement, your healthcare provider will start with a physical exam. During the exam, your healthcare provider may feel certain points in the hips to feel for symptoms of an ischiofemoral impingement. If your healthcare provider thinks you may have ischiofemoral impingement syndrome, they may request additional imaging tests, such as an x-ray or MRI, to confirm the diagnosis.

Treatments

There is no single strategy that is used to improve ischiofemoral impingement syndrome. Your healthcare provider might recommend you start with a mild treatment or self-care. For instance, they might have you limit your activities, especially ones that make your hips, buttocks, or groin hurt more. They might tell you to rest more or prescribe medicine to help with the pain and other symptoms.

If conservative measures do not help improve your condition, your healthcare provider may try injections that contain pain medicine and/or steroids to help control the pain.

If neither of these methods work to help the pain get better, your healthcare provider may recommend surgical treatments to fix the bone.

Prevention

An ischiofemoral impingement syndrome cannot always be prevented. As it is sometimes caused by trauma, taking steps to avoid activities or accidents that can damage the hip and buttocks area may help prevent the condition.

What is Ischiofemoral Impingement?

Ischiofemoral impingement [imp-inj-ment] syndrome is a condition that happens when the ischium [ISH-ee-um] and the head of the femur are under extra pressure, usually because of trauma, overuse, or surgery.

The trauma, overuse, or surgery, can cause extra bone (also called bone spurs) to grow along one or both of the bones in the hip joint (called the ischium) This gives the bones an unusual shape that no longer fit together perfectly. Because they don’t fit together as well, the bones start to rub against each other more during movement, which creates friction that can damage the joint even more and cause pain over time.

As the friction gets worse and worse, the pain will also increase, and will usually limit activity over time. Treatment may involve anything from activity modification, to steroid injections, to surgery.
