Ceramic ball + metal socket approved
The first ever ceramic and metal total artificial hip system for patients as been approved this week.So, the hip joint consists of a ball-shaped bone at the top end of the thigh bone that fits into a rounded socket in the pelvis.
When the joint becomes worn and torn, total hip replacement surgery is needed to remove and replace damaged bone and cartilage.
In particular, a shell or cup replaces the socket, and a stem is inserted into the thigh bone and the ball shaped bone at the top of the stem is fitted inside the curved artificial socket where the ball can slide around for movement.
The new hip system is the first to combine a ceramic ball and a metal socket.
