The authors examine 83 consecutive cases of fracture and dislocation of the lower cervical spine submitted to surgery over a period of 5 years. Sixty-five patients were monitored with minimum 5-months follow-up, 5 died, 13 could not be traced. Lesions were classified based on the method proposed by Argenson3 with the purpose of identifying guidelines for surgical treatment. Thus, different methods are proposed based on the type of lesion and on any neurologic deficit. Intersomatic fusion with anterior approach is the method of choice in most lesions. The exception to this is monoarticular dislocations that cannot be reduced, so that reduction by posterior approach associated with discectomy and anterior fusion are recommended. Circumferential fusion is proposed for traumatic spondylolistheses, complete dislocations with unsatisfactory anterior reduction, in lesions in flexion-extension and rotation associated with complete spinal cord injury, in order to favor functional rehabilitation free from ortheses. The need to review many cases of traumatic lesions of the lower cervical spine (LCS) collected over a relatively short period of time derives from the need to identify guidelines that will help the surgeon in his or her choice of the type of surgery to perform on the patient with emergency injury. The basic premise, as for other sites of traumatic injury, resides in an efficient classification (corresponding to the anatomic injury and of immediate and intuitive application) to which options for treatment may be related. In particular, an evaluation of the type of approach (anterior, posterior, combined) and of the sequence of surgical stages is essential to obtaining effective results with an acceptable complication rate. Finally, treatment must be definitive, and in cases of severe spinal cord injury it must allow for rapid rehabilitation and freedom from the use of ortheses.
