Hip Replacement Motion & Stability
Larger head size more closely resembles femoral head of a healthy
Physicians and scientific engineers continually strive to make hip replacements even more successful by reducing the incidence of complication and improving the performance of the implant. Although infrequent, one of those complications is the risk of hip dislocation after the surgery. Hip dislocation occurs when the femoral head slides out of place during extreme motion. Three to four percent of patients receiving a total hip replacement experience hip dislocation.1
To help prevent dislocation, your doctor wants to make sure that the size of the implant closely matches the size and shape of your particular anatomy. Larger femoral heads are designed to allow for more motion and enhanced joint stability than smaller femoral heads. Stryker’s Anatomic Femoral Heads are larger in size, similar to the top of your femur, so they are anatomically sized for more natural hip performance. The result is a total hip replacement designed to help minimize dislocation and increase your range of motion.
