合并椎间盘突出的退变性腰椎滑脱椎间盘形态改变及其意义

【摘要】 目的：观察合并椎间盘突出的退变性腰椎滑脱（lumbar degenerative spondylo-listhesis,LDS）患者的椎间盘影像学特点,探讨椎间盘退变程度、椎间隙角度及高度与退变性腰椎滑脱间的关系。方法：以2009年10月～2011年11月我院和石景山医院收治的合并L4/5椎间盘突出的退变性腰椎滑脱患者37例作为观察组,另选同期单纯L4/5椎间盘突出症患者38例作为对照组,对L4/5椎间盘退变程度按照Pfirrmann法分级,CT测定L4/5椎间盘正中矢状面的椎间隙角度和椎间隙高度,对所得数据进行统计分析。结果：观察组L4/5椎间盘MRI退变程度B、C、D、E级分别为1、25、8及1例,对照组分别为2、21、13及2例,两组椎间盘退变程度间差异没有显著性（P>0.05）;CT测量L4/5椎间隙角度观察组和对照组分别为3.08°±1.87°和6.48°±2.92°,对照组椎间隙角度明显大于观察组（P<0.05）;椎间隙高度观察组和对照组分别为8.46±1.81mm和9.38±2.46mm,两组间比较差异没有显著性（P>0.05）。结论：椎间隙角度减小,可能是退变性腰椎滑脱发病的重要因素之一。     

颈椎间盘突出的MRI测量及MRI临床应用价值

Disc degeneration of cervical spine on MRI in patients with lumbar disc herniation: comparison study with asymptomatic volunteers

An association between progression of cervical disc degeneration and that of lumbar disc degeneration has been considered to exist. To date, however, this association has not yet been adequately studied. Age-related changes in the cervical intervertebral discs were evaluated by magnetic resonance imaging (MRI) in patients with lumbar disc herniation, and compared with the MRI findings of healthy volunteers without lower back pain. The purpose of this study was to clarify whether the prevalence of asymptomatic cervical disc degeneration is higher in patients with lumbar disc herniation than in healthy volunteers. The study was conducted on 51 patients who were diagnosed as having lumbar disc herniation and underwent cervical spine MRI. The patients consisted of 34 males and 17 females ranging in age from 21–83 years (mean 46.9 ± 14.5 years) at the time of the study. The control group was composed of 113 healthy volunteers (70 males and 43 females) aged 24–77 years (mean 48.9 ± 14.7 years), without neck pain or low back pain. The percentage of subjects with degenerative changes in the cervical discs was 98.0% in the lumbar disc herniation group and 88.5% in the control group (p = 0.034). The presence of lumbar disc herniation was associated significantly with decrease in signal intensity of intervertebral disc and posterior disc protrusion in the cervical spine. None of the MRI findings was significantly associated with the gender, smoking, sports activities, or BMI. As compared to healthy volunteers, patients with lumbar disc herniation showed a higher prevalence of decrease in signal intensity of intervertebral disc and posterior disc protrusion on MRI of the cervical spine. The result of this study suggests that disc degeneration appears to be a systemic phenomenon.

Massive lumbar disc herniation with complete dural sac stenosis

Background:

Large lumbar disc herniation (LDH) has been reported to have a greater tendency to resolve in clinical and pathomorphological evolutions. However, various definitions of large LDH have been used without validation, and the clinical symptoms of large LDH have not been fully elucidated. We conducted a retrospective analysis to determine the clinical characteristics and treatment outcome of massive LDH with complete dural sac stenosis

Materials and Methods:

We retrospectively reviewed 33 cases of LDH with complete dural sac stenosis on magnetic resonance imaging. Complete dural sac stenosis was defined as no recognizable rootlet and cerebrospinal fluid signal on T2-weighed axial MR images. The clinical outcome parameters included back pain, leg pain, Oswestry disability index (ODI), and neurological dysfunction. The paired t-test and Wilcoxon''s signed rank test were used to compare serial changes in back pain, leg pain and neurological dysfunction.

Results:

Mean duration of followup was 66 months (range 24 - 108 months). There were 24 male and 9 female. The mean age was 37 years (range 20 - 53 years). At presentation, mean visual analogue scales for back pain and leg pain were 75.3 ± 19.1 (range 12 - 100) and 80.2 ± 14.6 (range 0 -100), respectively. Mean ODI was 67.1 ± 18.8 (range 26 - 88). Neurological dysfunction was found in 9 patients (27.3%), and the bowel/bladder dysfunction was found in 2 patients (3.1%). Conservative treatment was performed in 21 patients (63.6%) with satisfactory results. Seven patients underwent decompressive surgery, and 5 underwent posterolateral fusion.

Conclusions:

A massive LDH with complete dural sac stenosis was found to be associated with severe back and leg pain at presentation, however surgical treatment can be deferred unless significant neurological symptoms occur.

Transradicular lumbar disc herniation: An extreme variant of intraradicular disc herniation

Intradural or intraradicular lumbar disc herniation (IDH) is a relatively rare condition often diagnosed intraoperatively. We encountered an extreme variant of IDH - a transradicular herniation as the disc material extruded through the lumbar nerve root through a split essentially transecting the nerve root. While failure to recognize intradural and intraradicular disc herniation can lead to failed back surgery, the variant described in the present case could lead to iatrogenic injury and complication if not recognized. A unique case of transradicular lumbar disc herniation in a 25-year-old patient is presented with the depiction of intraoperative images supplementing the text.
