 Hi, I am Dr. Ayya Panna. I am a consultant orthopedic surgeon at Manipal Hospital, Whitefield. So, today I will be talking about a very hot topic, especially in the post-COVID scenario, and it is called as bone death or avascular necrosis or AVN of the bones. So, AVN is a condition sometimes found in the hip or sometimes in the ankle or in the shoulder or around the knee where the blood supply reduces and gradually the bone dies. And the most common symptoms the patient come to with pain, dull pain in the hip and the thigh area. So, awfully, we are fighting a lot of patients who come to us because of this particular pain. They would be post-COVID, recovered from the COVID or immediately after COVID, and they would come with non-specific pain. And on examination, everything almost is normal and even X-ray could be normal. The release investigation which will pick up this particular condition is an MRI scan. So, if you are a post-COVID patient, if you have got pain, non-specific pain in the hip and the thigh area, please meet your surgeon to get evaluated for AVN.
