Abstract

Abstract:

BACKGROUND: Percutaneous hollow screw under X-Ray fluoroscopy has been shown to treat fracture of acetabulum of the pelvis, but the time of internal fixation was long, and the amount of radiation exposure to the patients and physicians was large.
OBJECTIVE: To test the application of the ISO-C^3D computerized navigational system for fracture of acetabulum.
METHODS: Thirty-one patients with fracture of the acetabulum were treated with percutaneous hollow screw under a fluoroscopy-based ISO-C^3D computerized navigational system. The interval from injury to operation was 4 to 13 days. All patients were followed up for one year.
RESULTS AND CONCLUSION: The average bleeding volume during operation was only 18 mL, except that the bleeding volume of only one patient, who suffered from the sacroiliacjoint injury and received open reduction and internal fixation, was up to 300 mL. The total number of screws used in the operation was 42, among which 24 were screws for acetabular anterior column fracture and 18 for posterior column fracture. All screws were implanted once precisely. The average time of internal fixation was 59 minutes, and the mean time for fluoroscopy was 39 seconds. The 31 patients were pain-free one week after the operation and no complication (infection, vascular nerve injury or implant breakage) was noted post-operatively. When the follow-up ended, radiography revealed fracture union with satisfactory screw fixation (no screw breakage or loosening). According to Matta functional scoring, results were excellent in 23 cases, good in 8 cases, with an excellent and good rate of 100%. According to Majeed functional scoring, the results were excellent in 22 cases, good in 6 cases and average in 3 cases, with an excellent and good rate of 90%. These results indicated that ISO-C^3D computerized navigational system can supply stable internal fixation without an increase of complication.
