Dual Mobility Prosthesis

A dual mobility prosthesis is a type of hip replacement designed to improve stability and reduce dislocation risk. It combines two articulating components: a large polyethylene (plastic) liner inside the metal hip socket, and a smaller ball attached to the thigh bone. This design allows for a greater range of motion while maintaining strong joint stability. It is especially beneficial for patients at higher risk of dislocation or with complex hip conditions. Overall, dual mobility prostheses aim to provide durable, stable, and comfortable hip function post-surgery.
