Curing temperatures vary with implant material and cement thickness (30°C to 70°C), whereas limits for the initiation of thermal bone damage are reported at 45°C to 55°C. Thus, optimizing surgical treatment and the implant material are possible approaches to lower the temperature. The aim of this study was to investigate the influence of water cooling on the temperature magnitude at the acetabulum cement interface during curing of a modular cobalt-chromium cup and a monoblock polyethylene acetabular cup. The curing temperature was measured for SAWBONE and human acetabuli at the cement-bone interface using thermocouples. Peak temperature for the uncooled condition reached 70°C for both cup materials but was reduced to below 50°C in the cooled condition for the cobalt-chromium cup (P = .027). Cooling is an effective method to reduce curing temperature with metal implants, thereby avoiding the risk of thermal bone damage.en1553-3506Surgical innovation20136607613http://rightsstatements.org/vocab/InC/1.0/acetabular replacementcementing techniquecuring temperaturethermal damageBone CementsChromium AlloysCold TemperatureMaterials TestingPolyethyleneProsthesis DesignHip ProsthesisMedizinInfluence of cooling on curing temperature distribution during cementing of modular cobalt-chromium and monoblock polyethylene acetabular cupsJournal Articleurn:nbn:de:gbv:830-8821882910.15480/882.154611420/154910.1177/155335061347917710.15480/882.1546Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG geförderten) Allianz- bzw.
