Four patients had Anderson Type II fractures and 6 patients had Type III fractures. Bone union was observed in all patients within 3 months after injury. After halo-vest fitting, cervical muscular atrophy increased with time, however, it gradually improved after removal of the halo-vest. Patients fixed with a halo-vest for more than 10 weeks complained of cervical discomfort and limited range of motion. No patients with fixation for less than 10 weeks had problems in bone union or had cervical complaints. Thus, less than a 10-week fixation period was considered to be appropriate.展开更多
