Abstract
Considerable advances have recently been made in improving cementing techniques in THA. It has been proposed that certain benefits in terms in reduction of curing time and increased bonding at the cement-stem interface, can be attained by the preheating of the femoral component prior to insertion. The aim of this study was to assess the clinical and radiological 5 year follow-up results of the preheating technique used for fixation of the femoral stem (Lubinus, Link, Germany).
100 consecutive patients (100 hips) with OA and an average age of 72 years (65–85) were operated on by a single surgeon in a single institution. two cohorts of 50 hips were randomised to either conventional cementing techniques, or with a preheated femoral component (40–50 degrees). The same cement was used in both cohorts (Cemex, Tecres, Italy). Follow up was clinical (Harris Hip Score) and radiological.
A reduction in curing time provides significant time savings without compromising implant performance. We recommend preheating of the femoral component for suregons experienecd in joint replacement and with a skilled surgical team.
