Case ReportsPrimary internal fixation of unilateral C1 lateral mass sagittal split fractures: a series of 3 cases.
Retrospective case review of adult patients who sustained C1 lateral mass sagittal split fractures treated with primary internal fixation. ⋯ Patients with a unilateral sagittal split of the C1 lateral mass can be successfully managed with primary open reduction and internal fixation with a transversely oriented construct using C1 lateral mass screws. Internal fixation of the atlas without fusion prevents progressive, painful deformity and the need for complex occipitocervical reconstruction procedures that have been reported with nonoperative management of these injuries.
