RESUMEN
<p><b>OBJECTIVE</b>To introduce percutaneous hollow screws for treatment of the vertical sacrum longitudinal fracture and evaluate the preliminary therapeutic outcomes.</p><p><b>METHODS</b>From January 1999 to December 2006, 24 cases with vertical sacrum longitudinal fractures inchuded 15 males and 9 females were treated by percutaneous hollow screws, with an average age of 35 years ranging from 18 to 61 years. Accordng to Denis'classification of sacral fracture, there were 6 cases of type I, 11 of type 1 and 7 of type II.</p><p><b>RESULTS</b>The operation lasted for 30 to 65 minutes (averaged 48 minutes). All of them were followed up for 3 to 36 months (averaged 18.6 months). According to improved effective standard of pelvic trauma, the result of radiography was excellent in 18 cases, good in 5 and poor in 1, and the clinical evaluation was exellent in 16, good in 8.</p><p><b>CONCLUSION</b>Treatment of the vertical sacrum longitudinal fracture with percutaneous hollow screws is a comparatively reliable method and has the advantages of more precise with few postoperative complications and allows the patient early mobilization.</p>
