Abstract:
Ten fresh cadaver specimens of cervical spine were divided into two parts in midsagittal plane after frozen. The sagittal diameters of spinal canal in hyperextention, neutral and hyperflexion positions were measured. Among the three position, the diameter was largest in hyperflexion position and the smallest in hyperextension. The changes in sagittal diameters appeared most markedly in C5-6,C6-7 and C4-5. Clinical significance was discussed in this paper.
