Abstract:
[Objective]To investigate the clinical effects of the internal fixation for fracture and dislocation of cervical spine with pedicle screws.[Method]Forty-one cases suffered from cervical fracture and dislocation were treated with Axis system.The patients all took X-ray,CT and MRI examinations before operations.Personal manipulation of every pedicle screw was attained according to the imaging measurement.[Result]All of the patients were followed up for six to twelve months postoperatively.One hundred and ninty-six of total 218 screws (90%) were in correct positon and 22 were incorrect.One nerve root injury and one doubtful blood vessel injury happened.Complete reduction and fracture union were obtained in 38 cases while inadequacy reduction and nerve root irritation existed in 3 cases,one of which suffered anterior approach operation on account of degeneration.Recovery didn't happen in the 6cases with complete spine injury.Ninteen cases with inadequacy spine injury recovered apparently even near normal level.[Conclusion]Cervical pedicle screw technique was identified to be safe and feasible for cervical fracture and dislocation.The key factors for a successful operation contain selection of patients,familiarity of the cervical anatomy,standard skill of manipulation and individuality of screw placement.
