Neglected Monteggia fracture: a review

Abstract

• Monteggia fracture is characterized by radial head dislocation combined with proximal ulnar fracture.

• If not diagnosed at an early stage, these lesions can gradually lead to forearm deformities and dysfunction, finally resulting in neglected Monteggia fracture. When the radial head is not reduced, several deformities develop at the humeroradial joint, including cubitus valgus and osteoarthritis.

• Adequate radiographs are crucial when the surgeons deal with forearm injuries.

• At present, proximal ulnar osteotomy and open reduction of chronic radial head dislocation provides satisfactory functional outcomes because of anatomic alignment reconstruction.

• Supplementary procedures, including transcapitellar pinning and repair or reconstruction of the annular ligament, which are performed in order to enhance stability of the humeroradial joint, should be thoroughly assessed based on joint rotational stability after reduction and on potential complications.
