Electrical stimulation in delayed union of long bones.

Area of Science:

• Orthopedics
• Biomedical Engineering
• Regenerative Medicine

Background:

• Fracture union in long bones can be delayed, necessitating innovative treatment approaches.
• The therapeutic potential of electrical stimulation for bone healing requires further clinical validation.

Purpose of the Study:

• To investigate the efficacy of direct current electrical stimulation in promoting fracture union of long bones.
• To determine optimal electrode placement for electrical stimulation therapy in delayed unions.

Main Methods:

• Developed a specialized electric stimulator delivering 15 microamperes current.
• Applied electrical stimulation to fractured long bones in 20 patients experiencing delayed union.
• Varied electrode placement, with a focus on negative electrode at fracture site and positive electrode proximally.

Main Results:

• Successful fracture union was achieved in 90% of treated patients.
• The average healing period was 9.25 weeks.
• Optimal results were observed with the negative electrode positioned at the fracture site.

Conclusions:

• Direct current electrical stimulation is a promising method for enhancing long bone fracture union.
• Specific electrode placement significantly influences treatment outcomes.
• The 20% infection rate warrants careful consideration and management strategies.
