Fractures in patients with diabetes mellitus should be treated primarily in terms of both fracture and blood glucose. Fracture treatment should include conservative treatment of simple fracture, repair of peripheral organ damage, and emergency surgery for multiple rib fractures. 1. Fracture aspect: the diagnosis and treatment plan should be made according to the severity of rib fracture. (1) Simple bone fracture or fracture: the fracture broken end is not obviously displaced, and conservative treatment methods such as chest strap or rib bone can be adopted. (2) Fracture damage to surrounding tissues: for example, if the fracture breaks through the lungs and causes a pneumothorax, the clinic will need to repair the pleura in addition to treating the fracture. (3) Multiple rib fractures: emergency surgery can be performed if necessary. The severity of rib fracture must be judged after the fracture, and should be examined in the hospital as soon as possible, and the clinic will make individualized diagnosis and treatment plan according to the condition. 2. Blood sugar: the most important part of the treatment program for diabetic patients is the combination of appropriate activities and diet control. After the fracture, diabetic patients will reduce their activities, which will affect the blood sugar situation. At this time, the amount of food should be adjusted according to the patient’s exercise level, and glucose-lowering drugs should be applied if necessary. At the same time, ensuring a balanced nutritional profile based on protein supplementation can help with fracture healing.
