Novel extracorporeal magnetotransduction therapy with Magnetolith and high-energy focused electromagnetic extracorporeal shockwave therapy as bone stimulation therapy for scaphoid nonunion

Abstract

Abstract Introduction: The case report describes a non-invasive combination of novel Magnetolith Extracorporeal magnetotransduction therapy (EMTT) with high-energy focused extracorporeal shockwave therapy (ESWT) for scaphoid nonunion. Patient concern: In March 2020, a 31-year-old male presented with significant left wrist pain with the epicenter in the radial fossa, limiting daily activities and sports. Initial injury happened in 2005 when the patient was 16-years-old which was neglected. The first scaphoid non-union surgery took place in 2012 with bone-grafting and Herbert-screw. The second revision surgery took place in December 2019. Diagnosis: CT scan showed a non-healing atrophic bone graft in the scaphoid region. Intervention: In March/April 2020, combined novel Magnetolith (EMTT, 8 Hertz, 6000 shots, energy level 6/8) with high-energy focused electromagnetic ESWT (0.35mJ/mm2, 4000 shots, 4 Hertz) was performed in 3 sessions on a weekly interval to accelerate bony healing. Outcomes: Cone-beam CT in May 2020 (5 weeks after the last combined EMTT/ESWT treatment) revealing bony consolidation. Conclusion: The combination of novel non-invasive Magnetolith (EMTT) with focused high-energy ESWT for 3 sessions on a weekly interval can significantly improve bony healing in scaphoid nonunion. To the best of my knowledge, this is the first report to apply EMTT & ESWT for scaphoid nonunion after failed surgeries.
