Low-Intensity Pulsed Ultrasound for Symptomatic Pseudarthrosis After Toe Fracture with Symphalangism: A Report of 2 Cases.

CASE: Distal phalangeal fractures are often treated conservatively. However, some patients experience residual pain. We report 2 cases of patients who underwent low-intensity pulsed ultrasound (LIPUS) therapy for pseudarthrosis after fracture of the distal phalanx of the fifth toe with symphalangism. Both patients (female, 63 and 33-year-old, respectively) underwent conservative treatment with buddy-taping fixation; however, bone union failed, and LIPUS therapy was initiated. In both cases, bone union was achieved and pain resolved after 3 months. CONCLUSION: Bone union occasionally fails after conservative treatment of distal phalangeal fractures. LIPUS is a useful treatment of symptomatic pseudarthrosis after such fractures.
