Posterolateral rotatory instability of the elbow occurs secondary to disruption of the lateral stabilizers of the elbow, including the lateral collateral ligament and extensor tendon origins. Although trauma is the most frequent cause for posterolateral rotatory instability, other nontraumatic factors may also play a role. Primary repair of the lateral ligament complex is advocated in the acute setting, whereas graft reconstruction is recommended in chronic instability.
