Joint Position and General Hypermobility Affect Elbow Joint Congruence on Magnetic Resonance Imaging: A Prospective Cohort Study
Patients with posterolateral rotational instability (PLRI) of the elbow exhibit a higher degree of joint incongruence on magnetic resonance imaging (MRI) than patients without PLRI. However, the influence of joint hypermobility and position of the elbow in healthy participants is yet unknown.
