Intercondylar fractures of the humerus are often associated with rotation of the fracture fragment and severe damage to the articular surface and may be accompanied by peripheral vascular and nerve injury, making them one of the more difficult fractures to treat in clinical orthopedics. Previous non-surgical treatment has made it difficult to achieve satisfactory repositioning and early functional exercise, resulting in the loss of most of the elbow joint function, and therefore the outcome of intercondylar humeral fractures is not very satisfactory. Due to the continuous development of internal fixation technology and the accumulation of treatment experience, open reduction internal fixation for intercondylar humeral fractures can achieve accurate anatomical repositioning of the articular surface and early functional exercise of the elbow joint, so this technique has gradually shown its great superiority and has achieved satisfactory results in clinical practice. The excellent rate of 80% in our group of 10 patients treated surgically also proves the superiority of surgical internal fixation. Intercondylar humeral fracture is a serious elbow trauma, and the fracture is mostly comminuted and can occur in the coronal, disarticulated and transverse planes, with the integrity of the articular cartilage surface destroyed and often accompanied by extensive damage to the joint capsule and surrounding vascular and neural tissues. Therefore, for open (or closed) fractures with vascular nerve injury, emergency fracture reduction and fixation and vascular nerve exploration and repair should be performed to maximize the vascular nerve and elbow joint function. For closed fractures without vascular nerve injury, surgical treatment should be performed when the soft tissue swelling is relatively mild before the appearance of tension blisters. If the swelling of the elbow is significant at the time of the patient’s visit, or if tension blisters are present, the swelling should be actively reduced and surgical treatment should be attempted within 1 week of the injury. Some scholars believe that the excellent rate of patients operated within 24 h after the injury is significantly higher than that of patients who received surgery more than 1 week after the injury, which may be related to the relatively clear anatomical structure of early surgery and easy anatomical repositioning and functional exercise. Therefore, the author believes that supracondylar humerus fractures should be treated as emergency surgery, and if combined with serious trauma to other organs of the body, they should also be treated actively and internal fixation should be performed within 1 week. For hospitals without treatment conditions, the fracture should be transferred to a higher level hospital in time to avoid delaying the best treatment time.
