Vertical atlantoaxial index: a new craniovertebral radiographic index.
An index for measuring the vertical relationship of atlas and axis is described. ⋯ VAAI can be an excellent measurement tool for the assessment of relationship of atlas and axis. Nonrheumatoid BI can be graded and classified depending on the value of VAAI.

Comparative StudyCervical range of motion and alignment after laminoplasty preserving or reattaching the semispinalis cervicis inserted into axis.
A radiographic study in 111 patients using radiographs was conducted. ⋯ This modified laminoplasty preserving the SSC inserted into C2 is an effective procedure for maintaining postoperative ROM, especially in extension, and sagittal alignment of the upper cervical spine well.

Anterior cervical discectomy and fusion (ACDF) is a common procedure for radicular and spondylotic disease of the cervical spine. Radiographs are routinely used to evaluate complications in the postoperative ACDF patient, especially airway compromise. Our purpose was to establish baseline data on the amount of change that can be expected in the prevertebral soft tissues after this procedure in the uncomplicated asymptomatic (no airway compromise) 1 or 2-level ACDF patient. Our hypothesis was that the upper cervical spinal levels (C2-C4) would experience greater degrees of swelling than the lower cervical spine (C5-C7). To date no published data exist in the English literature upon which to judge symptomatic patients (experiencing postoperative airway distress) radiographically. ⋯ As we predicted, the greatest edema was noted in the upper cervical spine. Studies need to be performed to compare the radiographic data of symptomatic patients with the baseline data we have collected.

Comparative StudyAnterior corpectomy with iliac bone fusion or discectomy with interbody titanium cage fusion for multilevel cervical degenerated disc disease.
Clinical and radiologic study evaluating the outcome after anterior corpectomy with iliac bone fusion compared with discectomy with interbody titanium cage fusion for multilevel cervical degenerated disc disease. ⋯ Either a multilevel discectomy and cage fusion with plating or a corpectomy and iliac bone fusion with plating provides good clinical results and similar fusion rates for cervical degenerative disc disease. However, absence of donor site complications and construct failures and shorter hospital stay make the multilevel discectomy and cage fusion with plate fixation better than corpectomy and strut graft fusion with plate fixation.
