![]() ![]() There are several ways that the amount of dysplasia can be measured on x-rays.Ī common measurement for the depth of the socket is the center-edge angle (C-E angle). X-rays can determine the severity of dysplasia, which helps to establish the need for surgery. Hip Joint pain radiates from the front of the thigh and or groin area. Note that the sockets are deep and contain the ball almost completely Note that the sockets are shallow and do not contain the ball (femoral head) Bilateral hip dysplasia in a young adult woman.X-Ray DiagnosisĪn x-ray can identify hip dysplasia by the shallow socket (acetabulum), and by displacement of the ball (femoral head) from the socket. The test for impingement is usually done by flexing the hip and then twisting the hip inwards to rub the femoral neck against the edge of the hip socket. This may occur when a torn labrum or the tender edge of the socket is pinched. This is called the Trendelenburg test.Ī test called the impingement test causes a pinching sensation in almost all patients with hip dysplasia. This dropping may also occur when standing on the affected hip. Motion is not normally limited by hip dysplasia although pain or muscle tightness is often noticed when the leg is spread away from the body – hip abduction.ĭuring walking most patients will limp because of dropping of the affected side of the pelvis. This is generally followed by moving the hip through a full range of movement. The doctor may have you stand to look for pelvic tilt, leg length discrepancy, or muscle wasting.

However, a painless limp can occur because of weak muscles, joint stiffness, bone deformity, or because the limp relieves the pain.Ī limp or pain does not necessarily mean that someone has hip dysplasia because limp and pain can be caused by many hip disorders. Limping is common during the early stages of hip dysplasia symptoms. The character of the pain may be sharp, or it may be a dull ache, or a combination of both from time to time. ![]() At first the pain may be mild or intermittent, but pain from hip dysplasia increases with time.Pain in the thigh or buttocks is uncommon unless there is also pain in the groin or side of the hip.Four out of five patients with hip dysplasia report this. A sensation of catching, snapping, popping, or locking that is usually painful.Pain at night when resting occurs in half of all patients with hip dysplasia.Hip pain increases when walking, standing or running in almost all patients with hip dysplasia.Muscle ache on the side of the hip or in front of the hip can also be caused by stabilizing hip flexor and abductor muscles that are overworked when the socket is shallow ( see anatomy and terminology).Pain from hip dysplasia is deep in the front of the groin in four out of five patients with hip dysplasia– this may be caused by labral tears, cartilage damage in the joint, or painful hip flexor muscles ( see anatomy and terminology). ![]()
