Hip impingement is thought to be a leading cause of hip osteoarthritis, and occurs due to deformities in the hip joint. However some individuals have these deformities but do not exhibit symptoms. Using the standard magnetic resonance imaging and clinical tests it is not clear which deformities will cause degeneration, requiring surgical intervention. We propose to evaluate the deformity and impingement between the femur and acetabulum using dynamic ultrasound imaging. Ultrasound does not involve radiation and can acquire video of the hip joint and is thus suitable for such diagnostic purposes. In this pilot study we will evaluate the feasibility of ultrasound in diagnosing hip impingement.

Study Design

Allocation non-randomized
Intervention model parallel assignment
Masking open label
Primary purpose screening
Subjects already scheduled to undergo surgical correction of a symptomatic cam-type hip impingement deformity. Subjects will undergo MRI and ultrasound investigation prior to surgery.
magnetic resonance imaging
Asymptomatic subjects with normal hip morphometry, as determined by MRI. Subjects will undergo MRI and ultrasound imaging.
