目的探讨经后路微创手术治疗神经根型颈椎病的疗效。方法采用后方小切口入路对32例神经根型颈椎病患者实行经后路微刨手术治疗,并对手术效果进行了临床随访观察。结果对14例年轻患者黄韧带增厚不明显、椎间盘质地较软者,在椎间孔扩大的同时行突出椎问盘切除,其余18例老年患者则因局部黄韧带明显增厚并有骨化,椎间盘质地较韧,切除困难,故只行椎间孔扩大,神经根减压;术后所有患者神经根痛症状均有改善,对28例患者进行了3~16个月的随访,术后没有出现颈部活动障碍和临床症状的复发。结论采用微刨手术治疗神经根型颈椎病,创伤小、安全、简捷、有效,一次手术即可切除绝大部分突出的椎间盘,在不影响颈椎稳定性的同时又完成了神经根减压 相似文献

OBJECTIVE: 76 patients who underwent laminoplasty for cervical spondylotic myelopathy were investigated regarding the impact of preoperative and postoperative degenerative spondylolisthesis on their neurologic outcome. METHODS: Radiographs were obtained 1 year postoperatively to investigate range of motion (ROM), lordotic curvature, and postoperative spondylolisthesis. RESULTS: By 1 year after surgery, 85% of those spondylolistheses present preoperatively had either resolved or improved on neutral lateral radiographs. The cross-sectional area of the spinal cord at the site of spondylolisthesis was measured using preoperative computed tomography myelography. Clinical results were evaluated by the recovery rate using Japanese Orthopaedic Association score. Patients with posterior spondylolisthesis showed a significantly poorer postoperative recovery rate. Intervertebral ROM in patients with preoperative spondylolisthesis was reduced, whereas cervical alignment had not deteriorated after laminoplasty. The group with posterior spondylolisthesis showed a significant reduction in the cross-sectional area of the spinal cord at the site of spondylolisthesis. Postoperative spondylolisthesis appeared in 15 patients, 10 of whom had preoperative spondylolisthesis at an adjacent site. CONCLUSION: The cause of poorer surgical results of those patients with preoperative posterior spondylolisthesis appears to be related to a higher degree of spinal cord compression than with preoperative anterior spondylolisthesis. 相似文献

目的 通过回顾性病例分析,评价单开门椎板成形联合椎间孔切开术(laminoplasty with foraminotomy, LF )与前路椎间盘切除减压融合术(anterior cervical discectomy and fusion,ACDF)治疗脊髓神经根型颈椎病的临床及影像学疗效。 方法 自 2008 年 1 月至 2010 年 1 月,按照纳入及排除标准选取 68 例患者纳入研究,ACDF 组 33 例,LF 组 35 例,随访均超过 2 年。疗效评估采用日本骨科协会(Japanese Orthopedic Association,JOA)评分及改善率,影像学评估采用 X 线片测量颈椎曲度和颈椎活动度(range of motion, ROM),末次随访时采用颈椎功能障碍指数量表(neck disabilitv index,NDI)评估两组患者颈肩部疼痛的改善程度。 结果 ACDF 组手术时间平均 187 min、出血量平均为 127 ml,与 LF 组(154 min、235 ml)比较,差异均有统计学意义(t 手术时间=4.170,P=0.000;Z 出血量=-6.888,P=0.000)。术后两组下肢感觉改善率(ACDF 组 64.0%、 LF 组 66.0%)的差异有统计学意义(Z=-7.512,P=0.000),而上肢运动、上肢感觉及下肢运动改善率的差异均无统计学意义。术后 3 个月时 ACDF 组出现 1 例植骨不融合,随访 2 年时 3 例出现邻近节段退变;而 LF 组未见并发症出现。末次随访时 ACDF 组在提物(Z=-3.947, P=0.000)及开车(t=-7.523,P=0.000)方面的 NDI 疼痛评分低于 LF 组。ACDF 组颈椎曲度由术前平均 13.7°增加至 16.2°,而 LF 组由 14.6°降至 13.3°(Z=-3.374,P=0.001)。两种术式均导致术后颈椎 ROM 下降(ACDF 组 14.8°、LF 组 16.5°),但差异有统计学意义(t=-2.167,P =0.034)。 结论 LF 在改善长节段颈椎间盘突出所致的颈椎髓性症状及根性症状方面与 ACDF 的临床效果相近,但具有手术时间短、手术技术相对简单、近期并发症发生率低等优势,是治疗混合型颈椎病安全、有效的手术方式。 相似文献

The purpose of this study is to establish the correct diagnosis of the location and extent of intraspinal cord lesions in cases of continuous or mixed-type ossification of the posterior longitudinal ligament and to estimate the postoperative prognosis using evoked spinal cord potentials (ESCP). Twenty-six patients, who underwent surgery from 1985 to 1987 and who have been followed for more than 6 months, were examined using a conductive ESCP, which demonstrates lower extremity, bowel, and bladder function, and a segmental ESCP and dermatome segmental ESCP, which demonstrate upper extremity function. A five-pole recording electrode was placed in the cervical epidural space. The stimulation sites were the thoracic epidural space for conductive ESCP, the median nerve at the elbow for the segmental ESCP, and the finger surface for the dermatome segmental ESCP. In cases in which the ESCP disappeared at the middle of the narrow cervical spinal canal, another stimulating electrode was placed in the cisterna magna, and a descending conductive ESCP was recorded to monitor the upper border of the spinal lesion. New findings, which could not be observed by roentgenograms, myelography, and CT scan, were detectable using this technique. 相似文献

HLA typing was carried out in 27 families with cases of ossification of the posterior longitudinal ligament (OPLL) in the cervical spine, with haplotype analysis for genetic factors. The results showed a significantly higher incidence of rare haplotypes in probands than in the general Japanese population, suggesting that certain genes linked to HLA are responsible for OPLL. On examination of the distribution of HLA haplotypes in families with members suffering from cervical OPLL, no evidence of OPLL was found in members with only one haplotype in common with the proband. In 9 of 15 siblings with two haplotypes in common, however, OPLL was observed. Further analysis of HLA haplotyping may contribute to the elucidation of the genetic determinants of OPLL linked to two HLA haplotypes, probably based on multifactorial inheritance. 相似文献

A case of delayed onset of C5-6 subluxation after a motor vehicle accident, with normal initial cervical spine roentgenograms and neurological findings consistent with concomitant cerebral trauma, is presented. Damage to the cervical spine was due to fractures of the C-6 body and superior articular facet undetected by routine radiologic studies. 相似文献

Cervical spine instability in children is rare but not exceptional and may be due to many factors. Although it mostly occurs
at the upper cervical spine, all vertebrae from the occiput to T1 may be involved. It may be acute or chronic, occurring secondary
to trauma or due to congenital anomaly, skeletal or metabolic dystrophy or rheumatoid arthritis. It can be isolated or associated
with other musculoskeletal or visceral anomalies. A thorough knowledge of embryology, anatomy, physiology and physiopathology
of the cervical spine in children is essential to avoid pitfalls, recognize normal variants and identify children at risk
of developing cervical spine instability and undertake the appropriate treatment. 相似文献

BACKGROUND Cervical spine instability is a clinical entity whose biomechanical and radiological features have been widely discussed by many authors. On the other hand, the subject of delayed post-traumatic cervical instability is often surrounded by confusion due to its difficult nosologic framing; the aim of this study is to contribute to the matter. METHODS A cooperative study was organized by the Study Group for Spinal Surgery of the Italian Society of Neurosurgery to evaluate cervical trauma patients surgically treated more than 20 days after the traumatic event. From a total number of 172 patients, twenty-five were admitted to the study, because neuroradiological investigations performed during the acute phase had shown either an absence of traumatic lesions or only minimal lesions judged to be stable. For this reason these 25 patients had not been treated by either surgery or immobilization in a halo vest. Some time after trauma, this group of patients clearly demonstrated evidence of unstable lesions requiring surgical treatment, following the appearance of new clinical signs or on neuroradiological follow-up. RESULTS Re-examination of the neuroradiological investigations performed during the acute phase made it possible to identify elements that might have led us to suspect the presence of ligamental lesions: microfractures, dislocations less than 3 mm, and inversion of physiological lordosis. CONCLUSIONS This review clearly indicates that patients with even mild cervical trauma must be scrupulously evaluated during the acute phase and that in some cases it is advisable to perform a more detailed neuroradiological investigation. 相似文献

Summary Twenty-six patients with cervical spondylosis and radiculomyelopathy were treated surgically. Eight patients had cervical laminectomy C 1-C 7, and 16 patients had complete cervical laminectomy C 1-C 7 with excision of the posterior rim of the foramen magnum. Follow-up of patients was from two months to eight years.The majority of patients improved markedly, and some of them had excellent results. 相似文献
