Abstract:
Objective To investigate the selection of surgery and clinical outcomes of upper cervical injuries.Methods 25 upper cervical injury patients were involved in this retrospective study from November 2011 to June 2014.Including 20 males and 5 females with mean age of 37.1 years old (range,14-55 years old).Individual operation methods were based on the comprehensive evaluation of specific situations including the clinical manifestation,the type of the injuries and the imaging data.HaloVest distraction was applicated before operation.The surgery by anterior approach were performed for 7 patients and posterior approach were performed for 18 patients.Preoperative and postoperative American Spinal Injury Association (ASIA) grade and Functional Independence Measurement (FIM) score were studied to evaluate the nerve functional restoration.Imaging data before and after the operation were contrasted to evaluate the reduction of the fracture,the bone union,the fusion of the bone graft and the condition of the internal fixation.Wilcoxon Singed Rank Test was applied to compare the FIM score between pre-operation and last follow-up.Results 15 patients presented neurological function deficit because of cervical spinal cord compromise.All cases were followed up for 6-35 months (mean 18.2 months),showing good clinical and radiological effects.Solid fusion was obtained in all patients among 3-12 months.The ASIA grade improved by an average of 1.1 (6 months after operation) and 1.2 (12 months after operation).There was significant difference in FIM score between pre-operation and last follow-up.One patient got cerebrospinal fluid leakage.Conservative treatment was implemented with the Trendelenburg position,rehydration fluids and so on.Removal of drainage tube 8 days later when the drainage was less than 30 ml/24 h.No incision infection,cerebrospinal fluid leakage,migration or breakage of internal fixation was observed at the last follow-up.Conclusion The type of upper cervical injuries are complicated,the characteristics of fracture,dislocation and nerve injury in different patients are different.The specific situation should be evaluated comprehensively to make individual operation methods.The success of the operation requires the proficiency of the anatomic basis,the biomechanical characteristics,precise entrance point and direction in operation,appropriate diameter of the screw and suitable depth of the screw road.
