However, more degenerative discs behave less predictably, and spine extension may result in significant posterior disc bulging.
然而，退变更严重的椎间盘的行为反应不可预期，脊柱的伸展可导致椎间盘显著的向后方的膨出。
Condclusion: the stability of the goat's cervical spine is not affected after PCD with CNL, but the procedure may cause disc space narrowing and disc bulging.
结论：经皮颈椎间盘切吸加溶核对山羊颈椎的稳定性无影响，但可引起手术间隙变窄和手术间盘纤维环膨出。
Results: The sagittal reconstruction was performed with all the the 79 lumbar disc lesions of lumbar vertebrae and rumpbone vertebrae. There were 31 cases of lumbar disc bulging.
结果：对腰椎、骶椎共79例病变部位行矢状重建，其中腰间盘膨出31例，腰间盘突出44例，正常4例。
A bulging disc can be found in thoracic regions of the back but is nearly always found in the lumbar region.
一鼓胀的光碟片可发现在胸地区的回，但几乎总是发现在腰椎地区。
Lumbar magnetic resonance imaging was conducted with quantitative or qualitative assessments of disc signal, bulging, and height narrowing at each lumbar level.
腰椎磁共振定性和定量评估间盘信号，膨出，和各个腰椎水平的高度狭窄。
These changes affect the way the vertebrae in the spine move and bone spurs can result as well as bulging or disc leakage, all of which can cause pain when they contact the spinal nerves.
这些改变影响脊柱的椎体的运动方式，导致骨刺及椎间盘突也或漏出。所有这些压迫脊神经时都会引起疼痛。
Objective To compare the therapeutic effectiveness of auto percutaneous lumbar discectomy (APLD) and percutaneous laser disc decompression (PLDD) in treating lumbar disc protrusion or bulging.
目的对比分析经皮自动腰椎间盘摘除术（APLD）和经皮激光椎间盘减压术（PLDD）的治疗效果。
The authors discussed the selection of patients and treatment of bulging lumbar disc. The method of percutaneous diskectomy at the L5-S1 level was also introduced.

Conclusion The total effective rate of PLD for bulging of lumbar disc or mild protrusion show 100%, and 60% for severe prolapse or extrusion.
结论经皮穿刺腰间盘切割术治疗重度突出及脱垂的总有效率为60 %，对腰间盘膨出及轻度突出的总有效率可达1 0 0 %。
