Following surgery, the surgeon will fill out an operative data collection sheet to record information such as: levels fused, type of instrumentation, pre- and post-operative sagittal alignment, and intra-operative complications (if applicable). Subjects will be randomized into the "collar" or "no collar" group immediately following surgery, using a computer generated randomization scheme, so as not to influence the surgeon's operative technique. If the patient is randomized to the "no collar" group, he or she will actually have a hard cervical collar placed in the operating room after surgery. This will remain in place for 1 to 2 days and be discontinued prior to discharge. If the patient is randomized to the "collar" group, he or she will have the hard cervical collar placed after surgery. The collar will be removed/exchanged for bathing, grooming, and dressing changes only. It will remain in place for 12 weeks.
