Acceleration of ossification by means of interferential current

Area of Science:

• Biomedical Engineering
• Orthopedics
• Regenerative Medicine

Background:

• Current clinical bone repair evaluation methods are subjective and lack statistical reliability.
• Animal models provide a standardized approach for evaluating bone healing interventions.
• Non-invasive methods for accelerating bone growth and repair are highly sought after.

Purpose of the Study:

• To evaluate the efficacy of the Dynamic Interferential Current Ossification System (DICOS) in accelerating bone healing.
• To establish a reliable, objective method for assessing bone repair using animal models.
• To determine the relationship between interferential current density and bone healing parameters.

Main Methods:

• Standardized artificial fractures were created in sheep for controlled experiments.
• Histological, chemical, radiological, and electron-microscopic analyses were performed.
• Computer-aided programs were used to cross-calculate the electrical field parameters.
• The study utilized 4000 Hz alternating current based on the interferential principle.

Main Results:

• Higher interferential current density correlated with increased new bone mineralization.
• Elevated extracellular alkaline phosphatase levels were observed with increased current density.
• Earlier weight-bearing capacity was achieved in animals treated with DICOS.
• The system demonstrated non-invasive transcutaneous application, pain relief, and edema resorption.

Conclusions:

• DICOS is an effective non-invasive method for accelerating bone growth and repair.
• Interferential current density is a critical factor in enhancing bone mineralization and healing.
• DICOS offers advantages including patient comfort, compatibility with implants, and improved microcirculation.
