Lee SH, et al. - The study was intended to investigate the associations between the degree of injury to the medial and lateral collateral ligaments (MCL and LCL) and associated fractures in individuals with a posterolateral dislocation of the elbow, using CT and MRI. Researchers designed a retrospective review including a total of 64 individuals who presented with a posterolateral dislocation of the elbow and who underwent CT and MRI between March 2009 and March 2018. They used MRI to distinguish contusion of the bone and collateral ligament injuries by tear, partial or complete tear. The lateral collateral ligament ruptures are mostly complete, while the MCL exhibits various degrees of injury, which are significantly correlated with the associated fractures in posterolateral dislocation of the elbow.
