Advanced MRI techniques in hip cartilage assessment

Hip deformities are the main cause of hip pain and osteoarthritis in young adults, oftentimes necessitating hip-preserving surgery or, in more severe cases, a hip replacement. In order to successfully perform these surgeries and ensure the best possible outcome, surgeons rely on various imaging techniques. However, these techniques only produce 2D images which fail to accurately depict the complex 3D anatomy of the hip, and composing 3D models out of 2D images is a very time-consuming process. New technologies and techniques are applied in an attempt to automate 3D imaging and make it more convenient and reliable for hip cartilage assessment.

Hip deformities, such as femoroacetabular impingement (FAI) and developmental dysplasia of the hip (DDH), are leading causes of hip pain and early osteoarthritis in young adults, often resulting in the need for total hip replacement.1 FAI is caused by an early bony conflict between the pelvis and femur which results from osseous deformities and damages the labrum and cartilage over time. In DDH, inadequate coverage of the femoral head by the acetabulum leads to increased stress to the acetabular rim. Hip-preserving surgeries aim to correct these deformities and improve joint biomechanics, potentially delaying joint degeneration. However, challenges remain.
