ABSTRACT

Introduction: Ultrasound effect on fractures produces a mechanical pressure that stress bone an surrounding tissues. Duarte in 1983, demonstrate an increase of bone callus. Materials and methods: We study two groups of 15 patients, age range 15-61 years old, both genders, analyzing localization and type of fracture, metallic implant, time of consolidation, applying in group 1 ultrasound and group 2 without ultrasound (0.3 w/cm2 for 10 minutes at fracture site). Statistics: Student’s T. Results: Type transverse and short oblique fracture at bone shaft with Hunec’s nail and DCP plate in radius and ulnar bone. Consolidation grade 2: group 1, 52 days, group 2, 32 days without significant differences. Consolidation grade 3: group 1: 132 days, group 2, 79 days ( p= 0.0001). Discussion: Ultrasound diminished inflammation, increases vascularization and alkaline phosphatase increasing calcium and increasing proteins, fibroblast DNA synthesis that can accelerate the consolidation process. Conclusions: ultrasound application on site of fracture produces a mechanical stress and a piezoelectric effect on bone and generating growth in tissues, reducing time of bone consolidation.
