5 Posterolateral Rotatory Instability of the Elbow in Association with Lateral Epicondylitis Non-operative management, including avoidance of provocative maneuvers, elbow bracing, and pain control may be attempted in mild cases or where surgery is contraindicated. 1 PLRI may present after trauma, lateral-sided elbow surgery, and severe cases of lateral epicondylitis (typically after corticosteroid injections), or manifest late in patients with cubitus varus. Posterolateral rotatory instability (PLRI) occurs when the proximal ulna and radial head subluxate as a unit off the humerus in a rotatory fashion. Buddy Savoie. Fracture of the anteromedial facet of the coronoid process with injuries to the anterior and posterior bundles of the ulnar collateral ligament and to the lateral ligaments, consistent with varus posteromedial rotatory instability of the elbow (PMRI).
