About

One of the leading causes of hip arthritis is developmental dysplasia of the hip (DDH). DDH can lead to major damage in the hip joint and may result in hip arthritis later in life. Patients recruited into this study will be undergoing corrective hip surgery within the next 6 months with a goal of preventing further hip problems down the road. This study is being done to see how well a newer type of Magnetic Resonance Imaging (MRI) detects hip cartilage damage compared to an older but well validated MRI method.

Full description

The start of arthritis can first be detected in certain molecules in the joint. Proteoglycan is a molecule that is important to cartilage structure, and is lost as arthritis develops. Magnetic resonance imaging (MRI) is one of the best ways to image cartilage, and an investigational MRI technique that has shown great promise in detecting proteoglycan amounts is called T1-rho.

In this study, patients with hip dysplasia will undergo this investigational MRI in addition to a well validated MRI method (called dGEMRIC) to see if T1-rho is as good as dGEMRIC at detecting cartilage damage. The dGEMRIC MRI requires an injection of a contrast agent, while the T1-rho MRI does not. If the T1-rho is shown to be as useful as the dGEMRIC method it can then be used to look at cartilage damage in the hip without having to have an injection.

• severe claustrophobia
• prior contrast allergic reaction

Trial design

25 participants in 1 patient group

Developmental dysplasia of the hip (DDH)

Description:

Patients will complete 2 magnetic resonance imaging (MRI): T1-rho and dGEMRIC. The T1-rho MRI does not require the injection of a contrast agent, while the dGEMRIC MRI requires a gadolinium injection to visualize cartilage in the hip.

Treatment:

Radiation: Magnetic Resonance Imaging (MRI)
