The risk of femoral head surgery in diabetic patients is generally higher than that of normal people, especially in patients with poor glycemic control, who are prone to adverse events such as infections, anesthesia accidents, poor wound healing, and acute complications of diabetes. The period of time before, during and after surgery is called the perioperative period. During the perioperative period, if diabetic patients have poor glycemic control, infections, anesthesia accidents, etc., may occur, which may affect the postoperative wound healing, or even serious postoperative infections and so on. Moreover, surgical stress will increase blood glucose, which will also increase the possibility of acute complications of diabetes. Before diabetic patients undergo surgery, they should maintain stable blood glucose and cautiously assess whether they have any comorbidities, including diabetic retinopathy, diabetic nephropathy, heart disease and so on. For those who require femoral head surgery for diabetes, it is recommended that they actively cooperate with their doctor’s glucose-lowering regimen prior to surgery to stabilize their blood glucose control and minimize the risk of surgery.
