Abstract
Introduction: Cementing technique is one of the important factors which determines the longevity of cemented joint replacements. There are a number of variables which determine good cementation. We hope to standardise one of the variable which is cement working and setting time.
Methods: Cement was stored in a controlled temperature refrigerators at 20 degree centigrade and brought out just before mixing.
Theatre temperature, cement mixing start time and time at which cement was set were recorded for 20 hip and knee replacements. These recordings were also done for 20 hip and knee replacements where cement was stored in the theatre and was used as a control.
Results: Cement stored in the controlled temperature refrigerator had a more predictable working and setting time as opposed to controls.
Discussion: Cement stored in the controlled temperature refrigerator eliminates one of the variables in cemented arthroplasty and may prevent complication which could occur if cement sets unpredictably.
