Title: IV–3 Treatment-Targeting Based on Ultrasonographic Examination can Improve LIPUS Treatment Results in Delayed Union
Abstract: Background: We have reported that the heal rate after delayed union of humerus and femur is inferior to tibia and radius/ulna. One of the reasons for this discrepancy may be the difference in the distance from the skin to the fracture site. We hypothesized that the ideal site and direction for application of LIPUS could be determined by ultrasonography. Objective: To investigate whether ultrasonographic targeting for LIPUS can improve the heal rate after delayed union of humerus and femur. Study Design: Retrospective cohort study. Patients: Sixty-nine consecutive delayed unions of humerus (n = 19) or femur (n = 50), for which LIPUS was applied three months or more after surgery or injury. Site and direction for application of LIPUS were determined by ordinal x-ray or by a combination of x-ray + ultrasound (US). Main Outcome: Radiographic bone union without additional surgical procedures. Results: Forty-three bones (15 humerus and 28 femurs) were targeted by x-ray alone, and 26 bones (4 humerus and 22 femurs) were targeted by x-ray + US. Bone union rate with x-ray was 58% (60% for humerus, 57% for femurs) and with x-ray + US was 77% (75% for humerus, 77% for femurs). Bone union rate was significantly higher when x-ray + US was used (P < 0.05). Conclusion: Targeting with US can improve LIPUS treatment results after delayed union of humerus and femur.
