The BIRMINGHAM HIP
◊ was introduced in 1997 and has been unchanged since that time. All the other metal-on-metal resurfacings available worldwide today were introduced after the BIRMINGHAM HIP
◊ and are based in part on the BIRMINGHAM HIP
◊ design. Most companies wanted to change their design to try to differentiate from the leader, and today, these design changes have not been shown to be an improvement.
Whether it is the metallic properties, the way it is held to the bone, or the sizing, these changes have not been shown to have the success the BIRMINGHAM HIP◊ has had.
Remember, the BIRMINGHAM HIP◊ is proven to successfully treat hip arthritis in younger, more active patients.
