Reconstruction of posttraumatic elbow instability.
Successful reconstruction of posttraumatic elbow instability depends on restoration of the anatomic contributors to stability. The osseous and articular structures are paramount. The radial head and coronoid should be repaired or reconstructed and the olecranon (proximal ulna) should be repaired in anatomic alignment so that the contour and dimensions of the trochlear notch are restored and the radiocapitellar joint is aligned appropriately. The lateral collateral ligament complex is commonly disrupted and usually can be reattached to its origin from the lateral epicondyle. Patients with longstanding subluxation or dislocation may require temporary hinged external fixation or reconstruction of the collateral ligaments with tendon grafts.
