文题释义:
胸腰椎骨折:传统分类及手术方法常忽视了胸腰椎骨折伴随的椎间盘损伤,椎间盘是一个重要的维持活动节段高度的成分,在胸腰椎力学成分中占有重要地位,不同形式的损伤和愈合都会对脊柱的长期稳定性产生影响。
后路椎弓根螺钉内固定:为胸腰椎骨折的标准术式,单纯后路短节段内固定手术对骨折椎临近损伤的椎间盘未予处理,保留了其活动度,可以减少了临近节段的负荷,显著减少了邻椎病的发生。
 

背景:胸腰椎骨折多伴有临位椎间盘的损伤,传统后路短节段内固定术对损伤的椎间盘未予处理,它可能是是术后导致患者后凸畸形的主要原因。
目的:探讨椎间盘损伤对单椎体胸腰椎骨折患者行后路单纯短节段内固定后后凸畸形角度的影响。
方法:分析2009年1月到2014年6月济南市中心医院收治的单椎体胸腰椎骨折患者40例,分别于术前、术后2,12个月和内固定取出后6个月进行随访,获得X射线和MRI资料。根据术前MRI影像按椎间盘损伤与未损伤分为观察组17例和对照组23例,对两组患者各随访时间点椎体楔变角、矢状位后凸角、骨折椎上位椎间盘角、矢状位比例指数和骨折椎上位椎间盘退变分级数据进行分析。平均随访23.6个月(18-30个月)。
结果与结论:①影像学参数:两组患者在内固定取出后6个月矢状位后凸角均显著大于术后2个月(P < 0.05);观察组患者矢状位后凸角、骨折椎上位椎间盘角、矢状位比例指数在术后12个月和内固定取出后6个月时均显著大于对照组(P < 0.05);②椎间盘退变分级:观察组患者骨折椎上位椎间盘Pearce退变分级在术后12个月和内固定取出后6个月时显著高于对照组(P < 0.05);③结果说明:胸腰椎骨折患者行单纯后路短节段内固定后,均会发生后凸畸形,而椎间盘损伤会导致更为严重后凸畸形。

Abstract:

BACKGROUND: Thoracolumbar fracture often accompanies with the injury of adjacent intervertebral disc. Traditional posterior short-segment fixation does not deal with the injured intervertebral disc, which may be the main reason for kyphosis in patients after surgery.

OBJECTIVE: To investigate the effect of injured intervertebral disc on kyphosis angle in patients with single vertebral thoracolumbar fracture after treated with posterior short-segment fixation alone.
METHODS: From January 2009 to June 2014, 40 cases of thoracolumbar fractures were treated in Jinan Central Hospital. They were followed-up at preoperation, 2 and 12 months after operation and 6 months after internal fixation removal. Data were obtained from X-ray and MRI scanning. According to the preoperative MRI images, cases were assigned to observation group (17 cases) and control group (23 cases) according to injury and non-injury intervertebral disc. Data of vertebral wedge angle, sagittal plane kyphosis, proximal intervertebral disc angle, sagittal index and degeneration classification of proximal intervertebral disc angle from two different groups were analyzed at each follow-up time point (18-30 months, averagely 23.6 months).
RESULTS AND CONCLUSION: (1) Imaging parameters: sagittal plane kyphosis was significantly severer at 6 months than that at 2 months in both groups (P < 0.05). Sagittal plane kyphosis, proximal intervertebral disc angle and sagittal index were greater in the observation group than in the control group at 12 months after surgery and 6 months after fixator removal (P < 0.05). (2) Degeneration classification of proximal intervertebral disc angle: Pearce degeneration grade of proximal intervertebral disc was significantly higher in the observation group than in the control group at 2 months after surgery and 6 months after internal fixation removal (P < 0.05). (3) Results suggested that kyphosis may appear in the patients with thoracolumbar fracture after a posterior short-segment fixation alone, and the injured disc may lead to more severe kyphosis.
