OPS-Code 5-801.hq:

You had an operation on your foot to renew damaged cartilage.

The foot is made up of a lot of small bones and joints. The lower leg is connected to the tarsus. Then comes the metatarsus and then the individual toes.The metatarsus consists of 5 elongated metatarsal bones.The big toe consists of 2 toe bones. The other toes consist of 3 toe bones.The bones in a joint are covered with cartilage. When the joint is moved, the cartilage prevents the bones from rubbing against one another. The cartilage is normally strong and elastic, with a smooth surface.

Cartilage in one or more of the joints between your metatarsal bones and your toe bones was damaged. The operation involved opening the affected joints via an incision through your skin. First, the damaged cartilage was removed. Then, small holes extending into the bone marrow were created in this area.The bone marrow is inside the bone. The blood cells are formed in the bone marrow, for instance. The bone marrow also contains fat.Blood from the bone marrow enters the joint through these small holes. Blood vessels can also grow into the joint. This is intended to generate new tissue that replaces the cartilage.
