Background Context

Conventional laminoplasty is useful for expanding a stenotic spinal canal. However, it has limited use for the decompression of accompanying neural foraminal stenosis. As such, an additional posterior foraminotomy could be simultaneously applied, although this procedure carries a risk of segmental kyphosis and instability.

Purpose

The aim of this study was to elucidate the long-term surgical outcomes of additional posterior foraminotomy with laminoplasty (LF) for cervical spondylotic myelopathy (CSM) with radiculopathy.

Study Design/Setting

A retrospective comparative study was carried out.

Patient Sample

Ninety-eight consecutive patients who underwent laminoplasty for CSM with radiculopathy between January 2006 and December 2012 were screened for eligibility. This study included 66 patients, who were treated with a laminoplasty of two or more levels and followed up for more than 2 years after surgery.

Outcome Measures

The Neck Disability Index (NDI), Japanese Orthopedic Association (JOA) scores, JOA recovery rates, and visual analog scale (VAS) were used to evaluate clinical outcomes. The C2–C7 sagittal vertical axis distance, cervical lordosis, range of motion (ROM), and angulation and vertebral slippage at the foraminotomy level were used to measure radiological outcomes using the whole spine anterioposterior or lateral and dynamic lateral radiographs.

Methods

Sixty-six patients with CSM with radiculopathy involving two or more levels were consecutively treated with laminoplasty and followed up for more than 2 years after surgery. The first 26 patients underwent laminoplasty alone (LA group), whereas the next 40 patients underwent an additional posterior foraminotomy at stenotic neural foramens with radiating symptoms in addition to laminoplasty (LF group). In the LF group, the foraminotomy with less resection than 50% of facet joint to avoid segmental kyphosis and instability was performed at 78 segments (unilateral-to-bilateral ratio=57:21) and 99 sites. Clinical and radiographic data were assessed preoperatively and at 2-year follow-up and compared between the groups.

Results

The NDI, JOA scores, JOA recovery rates, and VAS for neck and arm pain were improved significantly in both groups after surgery. The improvement in the VAS for arm pain was significantly greater in the LF group (from 5.55±2.52 to 1.85±2.39) than the LA group (from 5.48±2.42 to 3.40±2.68) (p<.001). Although cervical lordosis and ROM decreased postoperatively in both groups, there were no significant differences in the degree of reduction between the LF and LA groups. Although the postoperative focal angulation and slippage were slightly increased in the LF group, this was not to a significant degree. Furthermore, segmental kyphosis and instability were not observed in the LF group, regardless of whether the patient underwent a unilateral or bilateral foraminotomy.

Conclusions

Additional posterior foraminotomy with laminoplasty is likely to improve arm pain more significantly than laminoplasty alone by decompressing nerve roots. Also, performing posterior foraminotomy via multiple levels or bilaterally did not significantly affect segmental malalignment and instability. Therefore, when a laminoplasty is performed for CSM with radiculopathy, an additional posterior foraminotomy could be an efficient and safe treatment that improves both myelopathy symptoms and radicular arm pain.  相似文献

目的观察颈后路椎管成形术联合C4—5椎间孔扩大术治疗多节段颈椎病的疗效。方法将142例多节段脊髓型颈椎病患者分为2组:A组67例行椎管成形术联合椎间孔扩大术,B组75例行单纯椎管成形术。观察2组神经功能恢复情况,轴性症状、颈椎曲度及稳定性的变化,比较C5神经根麻痹发生率。结果手术均顺利完成,未出现脊髓受损程度加重等情况发生。A组手术时间明显长于B组(P<0.05)。术后2组患者在神经功能恢复(JOA评分)、轴性症状(VAS评分)、颈椎曲度及颈椎活动度方面比较差异均无统计学意义(P均>0.05)。A组出现C5神经根麻痹1例(2%),B组出现7例(9%),2组比较差异有统计学意义(P<0.05)。结论颈后路椎管扩大成形术中,对C4—5椎间孔进行适当扩大可降低C5神经根麻痹的发生率,且不会对颈椎曲度、稳定性及术后轴性症状造成影响。  相似文献

目的 评价不同门轴位置对于单开门颈椎管成形术(EOLP)临床治疗效果的影响.方法 2006年2月至2007年2月,102名确诊脊髓型颈椎病并行EOLP手术的患者纳入本次随机对照研究.依据随机数字表法57例纳入研究组,门轴位置为侧块内侧缘,较对侧开门的位置宽,设定为宽开门组;另45例纳入对照组,门轴位于椎板外缘和开门位置对称,该组患者设定为窄开门组.随访24个月,对术后临床和影像学的各项指标进行统计分析.结果 术后24个月随访两组间比较:手术时间、出血量、日本骨科学会(JOA)评分增长率、颈椎前突指数、颈椎活动度差异均无统计学意义;两组患者手术后均获得了满意的神经功能改善,但是轴性症状评分和C5神经根麻痹发生率,窄开门组明显低于宽开门组(均P<0.05).结论 手术中适当将门轴位置内移既可以保证手术减压的效果,又可以限制脊髓过度后移,有效避免C5神经根麻痹的发生,降低轴性症状的发生程度.  相似文献

Background context

Spinal extradural arachnoid cysts are rare expanding lesions in the spinal canal. Total removal of the cyst and repair of the dural defect is the primary treatment for symptomatic spinal extradural arachnoid cysts.

Purpose

To report the usefulness of recapping T-saw laminoplasty in treating huge extradural arachnoid cyst.

Study design

Case report.

Methods

We report the case of a 43-year-old man who presented with a 2-year history of progressive muscle weakness and numbness of the lower extremities. Magnetic resonance imaging (MRI) showed a huge extradural arachnoid cyst at the T12–L3 level extending into bilateral neural foramina and severe posterior compression of the spinal cord and cauda equina.

Results

The patient underwent total resection of the cyst and closure of the communication. En bloc recapping T-saw laminoplasty of T12–L2 including the T12–L1 and L1–L2 facet joints was performed to obtain extensive exposure and preserve posterior stability. Postoperatively, the patient achieved complete recovery of neurologic functions. Follow-up MRI demonstrated no recurrence of the cyst. Bone union after laminoplasty was obtained within 6 months.

Conclusion

Total resection of the cyst and closure of the communication is curative for this rare lesion. Recapping T-saw laminoplasty provides extensive exposure for removal of a large cyst while allowing complete preservation of the posterior spinal elements.  相似文献
