文摘目的研究半椎板切除、全椎板切除及椎板回植成形对颈椎稳定性的影响。方法将14例新鲜成年绵羊颈椎标本(C2~7)分为两组,每组7例。每例标本均被施加前屈后伸、左右侧弯和左右轴向旋转6个方向3.0 N·m载荷,测量C3~6运动节段在不同载荷下的运动范围(range of motion,ROM)及中性区(neutral zone,NZ)。对第1组进行完整状态、C5半椎板切除和C4~6半椎板切除3种状态下标本ROM和NZ的测量。对第2组进行完整状态、C4~6全椎板切除和C4~6椎板回植成形3种状态下标本ROM和NZ的测量。结果与完整状态比较,C5半椎板切除和C4~6半椎板切除状态下标本ROM和NZ没有明显差异,且C5半椎板切除和C4~6半椎板切除两种状态之间标本ROM和NZ也没有显著性差异。与完整状态比较,C4~6全椎板切除与C4~6椎板回植成形状态下在前屈后伸载荷下ROM有显著增大(P<0.05)。C4~6椎板回植成形与C4~6全椎板切除状态比较,标本在后伸载荷下ROM明显减小(P<0.05);而其余载荷下,椎板回植成形和全椎板切除ROM之间没有显著性差异。结论半椎板切除后,颈椎标本ROM和NZ无明显增加,并不影响颈椎的稳定性。全椎板切除后,颈椎标本在前屈后伸载荷下的ROM和NZ明显增加,颈椎稳定性受影响。椎板回植成形术并没有明显改善椎板切除术后颈椎的稳定性。
