A study was made to assess the degree of kyphotic angulation after anterior cervical discectomy and graftless fusion. The possibility of a progressive increase in kyphotic angle was also examined. Fifty-two consecutive patients presenting for review after anterior cervical discectomy and graftless fusion were examined through the use of lateral cervical radiographs and the presence and degree of kyphotic angulation was examined. The majority of operated levels (66%) demonstrated 0-5 degrees of kyphotic angulation and a further 14 (24%) demonstrated between 6 degrees and 10 degrees of kyphotic angulation.
开展了一项研究，以评估颈椎前路椎间盘切除及无植骨融合术后后凸成角的程度。还研究了后凸角度逐渐增加的可能性。通过颈椎侧位X线片对52例连续接受颈椎前路椎间盘切除及无植骨融合术后前来复查的患者进行检查，并检查后凸成角的存在情况及程度。大多数手术节段（66%）后凸成角为0 - 5度，另有14个节段（24%）后凸成角在6度至10度之间。
