The relation between cervical discographic pain responses and radiographic images

OBJECTIVE: The purpose of this study was to investigate the relation between cervical discographic pain responses and radiographic images. DESIGN: Records were reviewed for a series of patients who had undergone cervical discography. SETTING: All patients were being treated at a spine specialty clinic. PATIENTS: A total of 269 discs were studied in 161 discographic procedures in patients with neck, shoulder, or arm pain. All patients underwent other diagnostic procedures before discography, including magnetic resonance imaging, computed tomography (CT), and CT/myelography. INTERVENTIONS: During the injection of contrast in each disc evaluated, the patient was asked if any pain was felt, and if so, was it similar or dissimilar to the pain typically experienced. OUTCOME MEASURES: Results were determined by analyzing the pain responses during disc injection with respect to imaged pathology seen on the axial CT discographic image of the disc. Results were further analyzed based on patient age. RESULTS: There was a significant relation between the radiographic image of the disc and the results of clinical pain provocation (p < 0.01; chi2). Among the 35 discs appearing as normal, clinical pain was provoked in only 14.3%. Among the 234 discs appearing as abnormal, clinical pain was provoked in 77.8%. The mean age of the patients with painless radiographically abnormal discs was significantly greater than that of the patients in the other subgroups of the study population. CONCLUSIONS: There was good agreement between the radiographic appearance of the disc and the pain provocation results. Discs that were painless but disrupted were found among older patients. Among such patients, discography may be particularly helpful in differentiating clinically significant abnormalities from those associated with aging.     

A case of post-traumatic cervicogenic headache treated by cervical cord stimulation

The case of a 26-year-old woman suffering from cervical trauma with disc herniation presenting with arm and neck pain is presented. She underwent cervical discectomy with fusion because the pain did not improve with medical therapies; as the neck pain resumed after surgery, a cervical cord neurostimulator was implanted, with improvement for cervicogenic headache. This report underlines the presence of two pathologies and the relationship between C2 and trigeminal pathways.

腰椎间盘退变MRI:与Modic改变相关的影像学分析

背景:部分椎间盘源性下腰痛患者MRI可出现Modic改变,但Modic改变的相关因素及Modic改变与椎间盘退变之间因果关系目前尚不十分清楚。目的:分析存在腰椎间盘Modic改变的下腰痛患者性别、年龄分布特点及腰椎间盘发生Modic改变的相关因素。方法:回顾性分析634例(2536个椎间盘)存在腰椎间盘Modic改变患者的性别、年龄分布特点,并分析腰椎间盘Modic改变与椎间盘突出或膨出、Schmorl结节、椎体滑脱、椎间盘解剖水平及椎间盘退行性改变程度的相关性。结果与结论:634例患者中,女性患者ModicⅡ、Ⅲ型出现率均较男性高,而ModicⅠ型出现率小于男性患者(P<0.001);40岁以上患者较40岁以下患者Modic各型改变的出现率均高(P<0.001)。2536个腰椎间盘中,有椎体滑脱、出现Schmorl结节、有椎间盘突出或膨出者Modic各型改变的出现率均比无此类表现者高(P<0.001);L4/5、L5/S1水平(低位)Modic各型改变的出现率均比L2/3、L3/4水平(高位)高(P<0.001);椎间盘退行性改变越严重,Modic各型改变的出现率越高(P<0.001)。椎间盘退行性改变分级、Schmorl结节与Modic改变有显著相关性。结果说明,腰椎间盘Modic改变与患者性别、年龄、椎间盘有无突出或膨出、有无Schmorl结节、椎体有无滑脱、椎间盘解剖水平及椎间盘退行性改变分级均有相关性。其中,椎间盘退行性改变分级、Schmorl结节与腰椎间盘Modic改变间的相关性最高,且椎间盘退行性改变分级较Schmorl结节与之相关性更高。     

Lower cervical disc prolapse may cause cervicogenic headache: prospective study in patients undergoing surgery

In 1983 Sjaastad published for the first time diagnostic criteria for cervicogenic headache. Until now there have been no prospective studies investigating whether cervical disc prolapse can cause cervicogenic headache. Between July 2002 and July 2003 50 patients with cervical disc prolapse proven by computed tomography, myelography or magnetic resonance imaging were recruited and prospectively followed for 3 months. Patients were asked at different time points about headache and neck pain by questionnaires and structured interviews. These data were collected prior to and 7 and 90 days after surgery for the disc prolapse. Fifty patients with lumbar disc prolapse, matched for age and sex, undergoing surgery were recruited as controls. Headache and neck pain was diagnosed according to International Headache Society (IHS) criteria. Twelve of 50 patients with cervical disc prolapse reported new headache and neck pain. Seven patients (58%) fulfilled the 2004 IHS criteria for cervicogenic headache. Two of 50 patients with lumbar disc prolapse had new headaches. Their headaches did not fulfil the criteria for cervicogenic headache. One week after surgery, 8/12 patients with cervical disc prolapse and headache reported to be pain free. One patient was improved and three were unchanged. Three months after cervical prolapse surgery, seven patients were pain free, three improved and two unchanged. This prospective study shows an association of low cervical prolapse with cervicogenic headache: headache and neck pain improves or disappears in 80% of patients after surgery for the cervical disc prolapse. These results indicate that pain afferents from the lower cervical roots can converge on the cervical trigeminal nucleus and the nucleus caudalis.
