Posterolateral rotatory instability of the elbow.
Since its original description by O'Driscoll in 1991, PLRI is becoming increasingly recognized as a significant cause of elbow pathology. It is well documented that this problem results from an insufficiency of the radial ulnohumeral ligament and its related lateral structures, and that this insufficiency is usually the result of elbow trauma. Diagnosis has improved with the introduction of the PLRI test to identify the instability and advancing MR imaging capabilities of illustrating the injury. Whereas open reconstruction was previously the only definitive treatment, improving arthroscopic techniques provide a satisfactory alternative in stabilizing the elbow.
