Abstract

In recent retrieval studies, overpenetration of cement, incomplete seating of the prosthesis with a resulting polar cement mass, or both have been associated with failure of current-generation femoral resurfacing arthroplasties. Cementing technique was found to strongly influence cement pressure, interface temperature, and cement penetration in the few cementing studies published on hip resurfacing arthroplasty. Component-filling cementing techniques resulted in a risk of incomplete seating, variable degrees of overpenetration of the interior area, and a lack of cement at the outer lower edges of the bone under the resurfacing components. This caused exposure to high temperatures, which can cause bone necrosis. The manual technique with high-viscosity cement showed advantages in our experimental work. It was possible to achieve high cement contents in the outer fixation area without the negative effects of interior area penetration.
