High cervical ossified ligamentum flavum (OLF) is rare and may cause progressive quadriparesis and respiratory failure. Our two patients had unilateral OLF between C1 and C4 levels. MR showed a unilateral, triangular bony excrescence with low signal and a central, intermediate or high signal on all pulse sequences due to bone marrow within. There was Type I thecal compression (partial deficit of contrast media ring). The first patient had a linear and nodular OLF with calcification within tectorial membrane, C2–3 fusion and unilateral C2-facetal hypertrophy; and the second patient, a lateral, linear OLF with loss of lordosis and C3–6 spondylotic changes. A decompressive laminectomy using “posterior floating and enbloc resection” brought significant relief in myelopathy. Histopathology showed mature bony trabeculae, bone marrow and ligament tissue. The coexisting mobile cervical vertebral segment above and congenitally fused or spondylotic rigid segment below the level of LF may have led to abnormal strain patterns within resulting in its unilateral ossification. In dealing with cervical OLF, carefully preserving facets during laminectomy or laminoplasty helps in maintaining normal cervical spinal curvature. 相似文献

The aim of this study was to analyze the clinical characteristics of thoracic ossified ligamentum flavum (OLF) and to elucidate prognostic factors as well as effective surgical treatment modality. The authors analyzed 106 thoracic OLF cases retrospectively from January 1999 to December 2008. The operative (n = 40) and the non-operative group (n = 66) were diagnosed by magnetic resonance imaging (MRI) and/or computed tomography (CT) imaging. We excluded cases exhibiting ventral compressive lesions causing subarachnoid space effacement in thoracic vertebrae as well as those with a coexisting cervical compressive myelopathy. Those in the operative group were treated with decompressive laminectomy as well as resection of OLF. The preoperative neurologic status and postoperative outcomes of patients, as indicated by their modified Japanese Orthopedic Association (mJOA) scores and recovery rate (RR), Modic changes, the axial (fused or non-fused) and sagittal (omega or beak) configurations of OLF, and the ratios of the cross-sectional area (CSA) and anteroposterior diameter (APD) of the most compressed level were studied. The most commonly affected segment was the T10–11 vertebral body level (n = 49, 27.1%) and the least affected segment was the T7–8 level (n = 1, 0.6%). The ratios of the CSA in non-fused and fused types were 77.3 and 59.3% (p < 0.001). When Modic changes were present with OLF, initial mJOA score was found to be significantly lower than those without Modic change (7.62 vs. 9.09, p = 0.033). Neurological status improved after decompressive laminectomy without fusion (preoperative vs. last mJOA; 7.1 ± 2.01 vs. 8.57 ± 1.91, p < 0.001). However, one patient exhibited transient deterioration of her neurological status after surgery. In the axial configuration, fused-type OLF revealed a significant risk for a decreased postoperative mJOA score (0–7, severe and moderate) (Odds ratio: 5.54, χ2 = 4.41, p = 0.036, 95% CI: 1.014–30.256). The results indicated that the new categorization of axial-type of OLF is a helpful predictor of postoperative patient outcome and fused type was related with poor prognosis. In OLF cases free from ventral lesions compressing the spinal cord, decompressive laminectomy is enough for successful surgical outcome. Therefore, early surgical treatment will be considered in cases with fused-type OLF compressing spinal cord even though they do not have myelopathic symptoms. 相似文献

胸椎黄韧带骨化症(OLF)是导致椎管狭窄、脊髓受压的重要原因之一,经常合并强直性脊柱炎、氟骨症、DISH病。本病多见于下胸椎,可局限、广泛甚至跳跃存在[1]。因其临床表现复杂多样,临床上往往诊断困难,易与颈椎病、腰椎管狭窄症相混淆。我院自2000年3月~2004年6月,应用椎管后壁切除治疗OLF14例,回顾性总结其临床特点,就影响疗效的因素进行探讨。1资料与方法1.1临床资料本组14例,均通过临床检查结合CT、MRI确诊为OLF,并经手术证实。其中男9例,女5例,平均年龄49岁(42~68岁),病史平均19个月(6个月~3年),症状多呈进行性加重。14例中累及… 相似文献

胸椎黄韧带骨化的病理组织学研究 总被引:2,自引:0,他引:2
目的:探讨黄韧带骨化的病理变化特点和发生机理。方法:利用组织病理学、组织化学和影像学检查对比研究正常黄韧带和12例骨化黄韧带的病理形态学特点。结果:组织学上可见病变早期出现胶原纤维肿胀、融合,进一步发生软骨化生,最终出现钙化和骨化。在肿胀融合的胶原纤维和软同有化生处可见阿新蓝(pH2.5)阳性的粘液性物质,根据病理学检查特点,结合影像学表现可将黄韧带骨化分为结节型(增生性)、周围型和弥漫型3种类型。结论:韧带的退行性改变是黄韧带骨化的基本原因;胶原纤维的肿胀融合及其粘液样变性是黄韧带骨化的起始病变;黄韧带骨化的大体类型代表着同一病变发展的不同阶段。 相似文献
