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.

被忽视的孟氏骨折：综述。

Monteggia骨折的特点是桡骨头脱位合并近端尺骨骨折。如果不及早诊断，这些病变会逐渐导致前臂畸形和功能障碍，最终导致被忽视的孟氏骨折。当桡骨头未复位时，肱桡关节会出现多种畸形，包括肘外翻和骨关节炎。当外科医生处理前臂损伤时，充足的 X 光片至关重要。目前，由于解剖对齐重建，近端尺骨截骨术和慢性桡骨头脱位的切开复位提供了令人满意的功能结果。辅助手术，包括经颅骨钉扎和修复或重建环状韧带，以增强肱桡关节的稳定性，
