Avaliação radiográfica dos pacientes submetidos a fixação percutânea com parafuso maciço para tratamento de fraturas da extremidade distal do radio

Objective  The present paper aims to present results from radiographic evaluations of patients with extra-articular distal radius fractures submitted to percutaneous fixation with a 3.5 mm solid screw. Methods  Analytical, descriptive and retrospective case series of 16 patients with evaluation of the radiographic parameters. Results  The average age of the study population was 46.5 years old (25-60 years old); 81.25% of the sample was female. The average time until surgery was 8.8 days (4-14 days). The mean preprocedural volar tilt was - 7.41° (-23.48°-5.29°, standard deviation [SD] ± 6.59°). The mean volar tilt immediately after surgery was 5.93° (SD ± 6.23°, p  < 0.001). There was no statistical difference in volar tilt values after 6 months of follow-up. The mean preprocedural radial height was 4.13 mm (-7.8 mm-9.5 mm, SD ± 5.06 mm). There was a statistically significant increase at the immediate postoperative period to 10.04 mm ( p  = 0.002), and a significant reduction at 6 months to 9.55 mm ( p  = 0.012). The consolidation rate was 100% with the technique used, with a minimal complication rate. No patient had infection or required a reoperation. Conclusion  The technique was effective for the treatment of distal radial extra-articular fractures at 6 months, with a low complication rate; radiographic parameters values were acceptable and close to the anatomical ones.
