Summary

Bone cement working time is influenced by polymethylmethacrylate (PMMA) polymerization rates. Temperature significantly impacts cement working time, interface strength, and tissue viability at the bone-cement interface.

Area of Science:

  • Biomaterials Science
  • Surgical Technology
  • Polymer Chemistry

Background:

  • Polymethylmethacrylate (PMMA) bone cement is widely used in orthopedic surgery.
  • The working time of bone cement is critical for successful surgical procedures.
  • Several factors influence PMMA polymerization, including temperature and component mixture.

Purpose of the Study:

  • To review the impact of cement mixture temperature on bone cement working time.
  • To analyze the effect of temperature on the interfacial strength of cement-bone and cement-metal interfaces.
  • To evaluate temperature-related tissue viability and cellular changes at the bone-cement interface.

Main Methods:

  • Literature review of studies investigating PMMA bone cement properties.
  • Analysis of factors affecting polymerization rate, including environmental and material temperatures.
  • Examination of research on interfacial bond strength and biological responses to bone cement.

Main Results:

  • Elevated temperatures generally decrease the working time of PMMA bone cement.
  • Temperature affects the mechanical properties and strength of the cement interfaces.
  • Changes in temperature can influence tissue response and cellular behavior at the bone-cement interface.

Conclusions:

  • Temperature is a critical, albeit partially controllable, factor influencing PMMA bone cement performance.
  • Optimizing cement temperature is essential for achieving adequate working time and robust interfacial fixation.
  • Further research into temperature modulation could enhance bone cement applications and patient outcomes.
