Intercondylar fractures of the humerus are still relatively common and complex fractures that are challenging to treat, and Watson-Jones (1946) considered them to be “one of the few fractures that are difficult to manage”. The medial and lateral condyles are often separated into separate bones in a “T” or “Y” shape, with loss of contact with the humeral stem and rotational displacement. The aim of treatment is to reconstruct the normal alignment of the joint, to obtain good alignment and to provide stable internal fixation, and to perform incisional internal fixation surgery whenever possible. How to prevent swelling and pressure pain in the elbow 1. To develop good habits: people with bad habits such as long-term smoking, excessive alcohol consumption, less movement and more sitting and low-calcium diet are prone to osteoporosis in old age. So do not smoke, drink less alcohol, do not drink strong tea, do not consume too much high protein food. 2, external protectors: recent reports show that external hip protectors can effectively reduce a person’s chances of hip fracture caused by a fall. This is also a preventive measure for fracture. 3. Encourage more activity: moderate exercise can strengthen the bones on the one hand, and maintain muscle strength and good balance on the other, reducing the chance of falls. This is also one of the ways to prevent fractures. 4. Home safety: Seventy-five percent of falls occur in your own home, especially in the bathroom, kitchen and other places. It is very important to provide a safe home environment to reduce the occurrence of fractures. Prevention of this fracture is relatively common. Treatment of intercondylar humeral fracture 1.Manipulation reset plaster brace fixation is applicable to type I and II fractures Fractures with mild separation, first squeeze both condyles to reset them, then rectify the displacement of the supracondylar area, and finally fix the elbow joint in neutral position for 4-6 weeks with long-arm plaster anterior and posterior brace. 2, can not be closed reset or for some reasons failed to timely treatment of open injury, feasible ulnar hawk traction, combined with closed rectification, in the process of traction can be early functional exercises. Traction is generally 4-6 weeks, or 4 weeks to traction and then 2 weeks of protective braking with plaster rest. 3.For accurate repositioning and early functional exercise, type III and IV fractures can be repositioned by incision, fixed with plates and screws, without external fixation as much as possible, and functional exercise of the elbow joint can be started within a few days to 2 weeks after surgery. 4.For elderly patients, patients with severe fractures and patients with other diseases that are not suitable for surgery or long-term fixation, a neck and wrist sling can be used to brake the elbow joint at 90° of flexion and start functional exercise early.
