➤ There are patterns of traumatic elbow instability that help a surgeon to anticipate which structures are injured.
➤ Patients treated for persistent subluxation or dislocation of the elbow more than two weeks after injury regain less motion and experience more adverse events.
➤ The primary goal of treatment is stable reduction of the ulnohumeral joint and functional elbow motion.
➤ Motion and pain are affected by contracture and scarring of the soft tissues, malalignment of the joint, fracture malunion, damage to the articular surface, and ulnar neuropathy.
➤ Biomechanical and clinical studies support treatment with radial head arthroplasty and/or coronoid reconstruction for patients who have osseous insufficiency.
