    This study investigated methylmethacrylate monomer sensitivity in orthopedic surgery patients. No link was found between cardiovascular reactions during femoral prosthesis cementation and the complement system (components 3 and 4).

    Area of Science:

    • Orthopaedic Surgery
    • Immunology
    • Biochemistry

    Background:

    • Methylmethacrylate monomer (MMA) is widely used in orthopaedic surgery for bone cement fixation.
    • Cardiovascular changes can occur during MMA-based cementation, but their underlying mechanisms are not fully understood.
    • The role of the complement system in these reactions requires further investigation.

    Purpose of the Study:

    • To assess the sensitivity to methylmethacrylate monomer in patients undergoing orthopaedic surgery.
    • To investigate the potential relationship between cardiovascular reactions during femoral prosthesis cementation and the complement system.

    Main Methods:

    • Studied 25 patients undergoing orthopaedic surgery with MMA-based cementation.
    • Monitored cardiovascular reactions during the procedure.

  • Measured serum concentrations of haemolytic complement, complement component 3 (C3), and complement component 4 (C4).

    • Main Results:

    • No correlation was identified between observed cardiovascular reactions and complement system activation.
    • Serum concentrations of C3 and C4 did not show a significant relationship with cardiovascular events during cementation.

    Conclusions:

    • The study found no evidence to support a link between the complement system and cardiovascular reactions during MMA cementation in orthopaedic surgery.
    • Further research may be needed to elucidate the mechanisms behind MMA-induced cardiovascular changes.
