Temperature Control of Bone Cement for Enhancing Applicability and Safety in Vertebroplasty

Abstract:

Vertebroplasty has been widely accepted in treatment of osteoporotic vertebral fractures. Polymerization of bone cement stabilizes the fractured vertebra by increasing its mechanical strength, thereby providing symptomatic pain relief. Many factors affect the reaction of polymerization of polymethylmethacrylate and, therefore, the reaction rate and injection permeability of bone cement. This may increase the probability of a surgeon missing the crucial period, leading to the increase of the risks of uneven cement distribution, cement leakage and premature hardening of cement. Hypothermic manipulation of bone cement is expected to reduce reaction rate and hence, extending the handling time. However, in a manner of reducing the environmental temperature of bone cement, there are still uncertainties on handling time, cement distribution pattern and injection permeability of cement. This study is thus designed to investigate the efficacy of temperature control for enhancing applicability and safety of bone cement.
