Treatment of Pedicular Fractures of the Axis by Screws Fixation.

บทคัดย่อ

          From 1987 to 1994, 9 pedicular fractures of the axis were treated by open reduction and screws fixation. There were 6 male and 3 female patients, age range between 20-65 years. Two 4.0 mm. cancellous screws with washers were used to fix the fractures after reduction in ture posteroanterior and upward direction parallel to the posterior pedicular border. Postoperatively, a plastic collar was worn for 3 weeks. Follow up from 4 to 24 months. Bone union were achieved in all patients by 12 weeks with painless normal to nearly normal neck motion in all directions.

          The author believes that auther's method is better than Judet's or AO group’s methods because the used of 4.0 mm. cancellous screws and the direction of 2 screws which inserted paralle to each other’s produced more bone holding power and more compresssion force at fracture sites. This operation is not dilfcult or dangerous as though if we know thoroughly the anatomy of the axis. The author believes that screws fixation will be one of the standard treatment of pedicular fractures of the axis in the future.
