Did you know that you are constantly developing new bones and after about every 10 years get an entirely new skeleton? Fascinating, isn’t it? To understand how this process — medically called remodelling — takes place, we reached out to experts who told us that all through human life, the body is continually removing old bones and replacing it with fresh ones.

“So, most of the adult human skeleton is replaced about every 10 years and this remodelling persists throughout life,” Dr R A Purnachandra Tejaswi, Consultant Orthopaedic Surgeon with Special Interest in Sports Medicine, Reconstructive Arthroscopy and Joint Preservation Surgery, Yashoda Hospitals Hyderabad told indianexpress.com, adding that about 20% of bone tissue is replaced annually by remodelling.

elucidating further, Dr Vaibhav Bagaria, Director, Department of Orthopaedics, Sir H. N. Reliance Foundation Hospital explained that the process of bone remodelling basically comprises two types of cells: osteoblasts and osteoclasts. “Osteoblasts are responsible for building fresh new bone, while its counterpart osteoclasts, are responsible for breaking down the old senescent bone,” he said.
