Osteoporosis surgery. Surgeon using a hammer and a metal tool to compact coral balls into a cavity in the bone of a patient suffering from osteoporosis. This is a degenerative disorder causing brittle bones. The coral (Biocoral) is a biomaterial which is produced from natural coral. It is similar to bone tissue, being 97 percent calcium carbonate. Its porosity allows new bone growth to penetrate and replace it as it is absorbed by the body. It can be combined with antibiotics which are absorbed with the coral, reducing infection risks. Photographed at the Clinique de l'Alma, Paris, France.
