Calcium sulfate hemi-hydrate when mixed with water results in the formation of a solid precipitated calcium sulfate dihydrate. Many factors affect the timing of this reaction, hence the need to quantify set times. This work developed a new simple acoustic technique to measure the setting times of a calcium sulfate bone cement loaded with different antibiotic mixes.
A new simple acoustic test has been developed and used to assess the effect of different antibiotic additions on the setting time of a ‘rapid cure’ calcium sulfate bone cement (STIMULAN). This technique gives ‘absolute’, reproducible and consistent results and can be used with very small quantities of cement.
