    Pulsed electromagnetic field treatment effectively heals ununited fractures in 64.4% of patients. Treatment effectiveness is clear within three months, guiding further clinical decisions for fracture healing.

    Area of Science:

    • Orthopedics
    • Biomedical Engineering
    • Regenerative Medicine

    Background:

    • Ununited fractures pose a significant clinical challenge, often requiring invasive interventions.
    • Noninvasive treatment modalities are sought to improve patient outcomes and reduce healthcare costs.

    Purpose of the Study:

    • To evaluate the efficacy of noninvasive, pulsed electromagnetic field (PEMF) treatment for ununited fractures.
    • To identify factors influencing the success rate of PEMF therapy in fracture healing.

    Main Methods:

    • A cohort of 149 patients with ununited fractures received noninvasive, pulsed electromagnetic field treatment.
    • Patient adherence, anatomic location, age, time since injury, and infection status were analyzed as potential variables.

    Main Results:

    • PEMF treatment achieved healing in 64.4% of patients.
    • Treatment effectiveness was predictable in over 85% of cases after three months.
    • Higher success rates were observed for tibial nonunions compared to femur or humerus.
    • Combined PEMF and bone grafting showed enhanced efficacy in some cases.
    • Younger patients and treatment initiated within two years of injury demonstrated better outcomes.
    • Infection did not significantly impact overall treatment success.

    Conclusions:

    • Pulsed electromagnetic field therapy is a viable, noninvasive option for managing ununited fractures.
    • Patient adherence, proper immobilization, and non-weight-bearing are crucial for successful outcomes.
    • Early intervention and specific anatomic locations correlate with higher healing rates.
