Hip impingement, also known as femoroacetabular impingement, involves a structural or mechanical issue with one’s hip joint and can affect people of all ages.1,2,3 In fact, this condition commonly affects active teenagers and young adults. This condition causes increased friction in the hip joint that can wear it down and cause pain in the short term and extensive damage in the long term.
This article will explore the early signs of hip impingement to help hip pain sufferers recognize the symptoms and seek treatment as soon as possible. It will also discuss how this condition can lead to arthritis if untreated due to cartilage being broken down and worn away with repetitive use
What Is Hip Impingement?
The human hip naturally allows for the top of the thigh bone to connect to the hip socket so that it can move smoothly in the socket.4 This smooth movement is facilitated by a smooth layer of cartilage that prevents bones from grinding on each other and to secure the thigh bone in its place.5
But in individuals with hip impingement, these bones do not move together smoothly and pain results.2,3 Deformities at the ball at the top of the femur and deformities of the hip socket are two common causes of hip impingement.
Early Symptoms of Hip Impingement
Many people who have hip impingement do not experience any symptoms at all in the very early stages of the disorder. But over time, individuals may begin to notice a limited range of motion in the hip and stiffness in the front thigh region and in the groin. Other individuals may notice a clicking or popping sensation in the hip joint during movement.
Although many hip conditions affect elderly adults, this one is most common among active people under the age of 40.6,8 Once symptoms are felt, it is likely that some cartilage damage has already occurred.
How Can Hip Impingement Lead to Arthritis?
People who have arthritis, as well as those who do not, can develop hip impingement. However, an untreated condition of hip impingement is actually a common cause of osteoarthritis.7
This is because hip impingement causes cartilage damage that is characterized by this painful form of arthritis. Hip impingement is often considered to be a pre-arthritic condition, which means that further damage may be prevented before the cartilage damage is very severe.8
The Importance of Early Detection
It can be very difficult to diagnose hip impingement, but early detection is the key to preventing osteoarthritis for many patients. A physician will typically conduct a physical exam to test the hip’s range of motion and order an x-ray, CT scan, or MRI to further inspect the health of the hip joint.9
When hip impingement is detected early, it may be possible to manage the condition by simply reducing certain physical activities and trying physiotherapy or injections. Many people with hip impingement pain use topical arthritis creams, such as JointFlex, to relieve their pain quickly and throughout the day. However, surgical intervention may be recommended for more serious cases of hip impingement, especially arthroscopic treatment to correct an impingement deformity.
