Detailed pictures obtained by functional myelography show that anteflexion causes substantial ventral movement of the myelon in the lower neck region. This lack of lateral stability can, in cases of degenerative kyphosis accompanied by dorsal osteophytic swelling across the intervertebral space, lead to constant irritation of the myelon sheath outside of the region concerned although the spinal canal is not constricted. If surgical treatment is necessary preference should therefore be given to Cloward's ventral fusion rather than to laminectomy.
功能性脊髓造影获得的详细图像显示,前屈会导致下颈部区域脊髓大量向前移动。在伴有椎间隙背侧骨赘肿胀的退行性后凸病例中,尽管椎管未狭窄,但这种缺乏侧向稳定性会导致相关区域外的脊髓鞘持续受到刺激。因此,如果有必要进行手术治疗,应优先选择克洛德腹侧融合术而非椎板切除术。
