Low-Intensity Pulsed Ultrasound Treatment for Non-unions of Long Bone Fractures in a Scottish District General Hospital

Objective: Despite advances in treatment, the management of fracture non-union remains a challenging and complex problem in orthopaedics. Low-intensity pulsed ultrasound (LIPUS) treatment has been shown to be an effective, non-invasive, affordable treatment option. This treatment was evaluated in a Scottish district hospital over a nine-year period, which included the COVID-19 pandemic. Materials and methods: This submission describes a case series at Dr Gray’s Hospital in Scotland, 18 patients in whom fracture non-union was treated using LIPUS. Results: An overall healing rate of 94% was achieved. Exogen™ (Bioventus LLC, NC, USA) proved to be most successful in oligotrophic non-union. No observed patient demographic appeared predictive of outcome. LIPUS treatment failed in one case. No significant adverse effects of LIPUS were detected. Conclusion: LIPUS represents a useful, cost-effective potential alternative to revision surgery. LIPUS may therefore be the preferred treatment when surgical intervention and face-to-face interactions are to be minimised, as during the COVID-19 pandemic.
