摘要
目的 评估单节段Discover人工颈椎间盘置换术对颈椎矢状面曲度的影响.方法 对2012年2月至2014年9月行单节段Discover人工颈椎间盘置换术的62例患者进行回顾性分析,男34例,女28例;年龄31～61岁,平均(45.2±8.2)岁.均为单节段颈椎间盘突出症,包括C3-4椎间盘突出3例,C4-5椎间盘突出12例,C5-6椎间盘突出34例,C6-7椎间盘突出13例.测量术前与术后3个月颈椎中立侧位X线片上手术节段椎间盘角、脊柱功能单位(functional spinal unit,FSU)角、C2～C7角、椎间盘前缘高度、椎间盘中央高度、椎间盘后缘高度、FSU前缘高度、FSU中央高度、FSU后缘高度,分析手术前后的变化情况.结果 全部病例获得随访,随访时间3个月.与术前相比,术后3个月椎间盘角由0.0°±4.2°增加至7.3°±3.9°、FSU角由2.3°±5.0°增加至6.9°±4.8°、C2～C7角由9.5°±10.8°增加至13.1°±9.1°、椎间盘前缘高度由(4.3±1.0) mm增加至(7.9±1.1)mm、椎间盘中央高度由(5.8±0.9) mm增加至(8.1±0.9)mm、椎间盘后缘高度由(3.7±0.9)mm增加至(5.5±0.9)mm、FSU前缘高度由(34.1±3.5) mm增加至(36.2±3.4) mm、FSU中央高度由(32.3±3.5) mm增加至(33.6±3.3) mm、FSU后缘高度由(33.9±3.5)mm增加至(34.6±3.2) mm,差异均有统计学意义(P＜0.05).结论 单节段Discover人工颈椎间盘置换术能够早期改善椎间盘角及FSU角、增加椎间隙高度,从而在一定程度上恢复颈椎的矢状面曲度.
Abstract
Objeetive To evaluate the effect of single-level Discover cervical artificial disc replacement on cervical sagittal alignment.Methods Retrospective analysis was conducted on patients who underwent single-level Discover cervical artificial disc replacement in our hospital from February 2012 to September 2014.Sixty-two patients (34 males,28 females) with an average age of 45.2±8.2 (31-61) who were diagnosed with single-level cervical disc herniation were included (C3-4 3 cases,C4-5 12 cases,C5-6 34 cases,C6-7 13 cases).We measured the cervical sagittal alignment parameters:index level disc angle,functional spinal unit (FSU) angle,C2-C7 angle,anterior disc height (ADH),middle disc height (MDH),posterior disc height (PDH),anterior FSU height (AFH),middle FSU height (MFH),posterior FSU height (PFH) on neutral lateral radiographs before surgery and 3 months after surgery.Results All of the patients were followed up for 3 months.The cervical sagittal alignment parameters before surgery and 3 months after surgery were as follows.Index level disc angle increased from 0.0°±4.2° to 7.3°±3.9°,FSU angle increased from 2.3°±5.0° to 6.9°±4.8°,C2-C7 angle increased from 9.5°±10.8° to 13.1°±9.1°,ADH increased from 4.3±1.0 mm to 7.9±1.1 mm,MDH increased from 5.8±0.9 mm to 8.1±0.9 mm,PDH increased from 3.7±0.9 mm to 5.5±0.9 mm,AFH increased from 34.1±3.5 mm to 36.2±3.4 mm,MFH increased from 32.3±3.5 mm to 33.6±3.3 mm,PFH increased from 33.9±3.5 mm to 34.6±3.2 mm.All changes were statistically significant (P＜0.05).Conclusion Single-level Discover cervical artificial disc replacement can improve the disk angle,FSU angle,and disk height effectively in early follow-up period,thereby improving the cervical sagittal alignment.
