目的:分析术前、术后椎间隙高度对单节段 Prestige LP 人工颈椎间盘置换术后置换节段活动度和临床效果的影响。方法2008年2月至2013年4月,63例患者在我院行 Prestige LP 人工颈椎间盘单节段置换术,其中男31例,女32例;年龄28~68岁,平均47.6岁。神经根型颈椎病32例,脊髓型颈椎病25例,混合型颈椎病6例。置换节段:C3~41例,C4 ~ 5 5例,C5~652例,C6~74例,C7 T11例。收集患者术前及术后门诊随访时颈椎正侧位及功能位 X 线片,利用 CANVAS 软件测量术前、术后椎间隙高度和目标节段屈伸活动度(range of motion,ROM),临床效果评价采用JOA 评分和 NDI 评分。研究术前、术后椎间隙高度对术后置换节段活动的影响,并进行椎间隙高度与术后置换节段活动度和临床效果的相关性分析。结果人工颈椎间盘置换术后置换节段 ROM 为(10.8±3.2)°,术前置换关节ROM 为(10.4±3.3)°,差异无统计学意义(P >0.05);术后置换节段椎间隙高度为(7.0 ± 0.9)mm,术前椎间隙高度为(4.6±1.0)mm,差异有统计学意义(P <0.05)。术前椎间隙高度小于4.0 mm 的患者,人工颈椎间盘置换术后置换节段 ROM 相比术前平均增加0.7°(P <0.05);而术前椎间隙高度大于4.0 mm 的患者,术后置换节段 ROM 与术前相比差异无统计学意义(P >0.05)。术后置换节段椎间隙高度大于6 mm 的患者术后 ROM 平均为11.3°,术后椎间隙高度小于6 mm 的患者术后 ROM 平均为8.8°,差异有统计学意义(P <0.05);而两组间术后 JOA 评分、NDI 评分差异均无统计学意义(P >0.05)。术后置换节段椎间隙高度小于8 mm 的患者术后 ROM 平均为11.2°,术后椎间隙高度大于8 mm 的患者术后 ROM 平均为9.1°,差异有统计学意义(P <0.05);两组间术后 JOA 评分、NDI 评分则差异无统计学意义(P >0.05)。术前、术后椎间隙高度与术后置换节段 ROM、术后 JOA 评分和 NDI 评分均无明显相关性。结论术前椎间隙高度小于4.0 mm 的患者行 Prestige LP 人工颈椎间盘置换术后置换节段活动度改善更明显。术后置换节段椎间隙高度主要在6~8 mm 时的置换节段活动度相对较大,但与患者术后神经症状的改善程度无关。
目的:分析術前、術後椎間隙高度對單節段 Prestige LP 人工頸椎間盤置換術後置換節段活動度和臨床效果的影響。方法2008年2月至2013年4月,63例患者在我院行 Prestige LP 人工頸椎間盤單節段置換術,其中男31例,女32例;年齡28~68歲,平均47.6歲。神經根型頸椎病32例,脊髓型頸椎病25例,混閤型頸椎病6例。置換節段:C3~41例,C4 ~ 5 5例,C5~652例,C6~74例,C7 T11例。收集患者術前及術後門診隨訪時頸椎正側位及功能位 X 線片,利用 CANVAS 軟件測量術前、術後椎間隙高度和目標節段屈伸活動度(range of motion,ROM),臨床效果評價採用JOA 評分和 NDI 評分。研究術前、術後椎間隙高度對術後置換節段活動的影響,併進行椎間隙高度與術後置換節段活動度和臨床效果的相關性分析。結果人工頸椎間盤置換術後置換節段 ROM 為(10.8±3.2)°,術前置換關節ROM 為(10.4±3.3)°,差異無統計學意義(P >0.05);術後置換節段椎間隙高度為(7.0 ± 0.9)mm,術前椎間隙高度為(4.6±1.0)mm,差異有統計學意義(P <0.05)。術前椎間隙高度小于4.0 mm 的患者,人工頸椎間盤置換術後置換節段 ROM 相比術前平均增加0.7°(P <0.05);而術前椎間隙高度大于4.0 mm 的患者,術後置換節段 ROM 與術前相比差異無統計學意義(P >0.05)。術後置換節段椎間隙高度大于6 mm 的患者術後 ROM 平均為11.3°,術後椎間隙高度小于6 mm 的患者術後 ROM 平均為8.8°,差異有統計學意義(P <0.05);而兩組間術後 JOA 評分、NDI 評分差異均無統計學意義(P >0.05)。術後置換節段椎間隙高度小于8 mm 的患者術後 ROM 平均為11.2°,術後椎間隙高度大于8 mm 的患者術後 ROM 平均為9.1°,差異有統計學意義(P <0.05);兩組間術後 JOA 評分、NDI 評分則差異無統計學意義(P >0.05)。術前、術後椎間隙高度與術後置換節段 ROM、術後 JOA 評分和 NDI 評分均無明顯相關性。結論術前椎間隙高度小于4.0 mm 的患者行 Prestige LP 人工頸椎間盤置換術後置換節段活動度改善更明顯。術後置換節段椎間隙高度主要在6~8 mm 時的置換節段活動度相對較大,但與患者術後神經癥狀的改善程度無關。

Objective To analyze the influence of pre-and postoperative disc height on postoperative range of motion (ROM)and clinical outcomes after single segment Prestige LP cervical disc replacement. Methods 63 cases underwent sin-gle segment Prestige LP cervical disc replacement from February 2008 to April 2013. All patients were examined on lateral and flexion-extension radiographs. The intervertebral height and flexion-extension ROM were measured by the CANVAS,and the clinical outcomes were evaluated by Japanese Orthopaedic Association(JOA)and Neck Disability Index(NDI). The influence of pre-and postoperative disc height on postoperative ROM was investigated,and the correlation between the disc height and postoperative ROM or clinical outcomes was analyzed. Results The postoperative segmental ROM was(10. 8 ± 3. 2)°,the preoperative segmental ROM was(10. 4 ± 3. 3)° without statistical significance(P > 0. 05). The postoperative disc height was (7. 0 ± 0. 9)mm,the preoperative disc height was(4. 6 ± 1. 0)mm with statistical significance(P < 0. 05). Patients with less than 4 mm of preoperative disc height had a mean 0 . 7 ° increase in flexion - extension ROM after cervical arthroplasty( P <0. 05),whereas patients with greater than 4 mm of preoperative disc height had no change in flexion-extension ROM(P >0. 05). The postoperative ROM of patients with greater than 6 mm of postoperative disc height was 11. 3°,the postoperative ROM of those with less than 6 mm of postoperative disc height was 8. 8° with statistical significance(P < 0. 05). The postoperative ROM of patients with less than 8 mm of postoperative disc height was 11. 2°,the postoperative ROM of those with greater than8 mm of postoperative disc height was 9. 1° with statistical significance(P < 0. 05),however,there is no significant difference in postoperative JOA and NDI between them(P > 0. 05). No correlation could be found between disc height and the postopera-tive ROM、JOA or NDI. Conclusion Patients with less than 4 mm of preoperative disc height benefit more in ROM after Pres-tige LP cervical disc replacement. The optimal postoperative intervertebral disc height range to maximize ROM is between 6 and 8 mm,however,the optimal range has no effect on clinical outcomes.
