Abstract：
Thoracic ossification of the posterior longitudinal ligament (OPLL) is a rare condition that is mainly accompanied by cervical OPLL or ossification of thoracic ligamentum flavum. In case of causing neurological manifestations, it is preferred to treat the condition surgically. Several surgical procedures were introduced, including anterior, posterior, or combined approaches. Laminectomy with instrumented fusion is the most popular procedure utilized via the posterior approach. A 32-year-old obese woman, who suffered from back pain and weakness in both lower extremities for one month, was referred to our spine outpatient clinic. Imaging revealed lower thoracic OPLL (T7/T8 & T8/T9 & T9/T10). The posterior longitudinal ligament had a mixed ossification pattern (beaked and continuing cylindrical). To maintain thoracic spine stability and prevent future kyphosis, we performed laminectomy and long segment fixation (T7 to T12). The post-operative neurological examination revealed a considerable increase in muscle strength and significant pain relief.
摘要：
胸后纵韧带骨化（OPLL）是一种罕见的疾病，主要伴有颈椎OPLL或胸椎黄韧带骨化。在引起神经系统表现的情况下，最好手术治疗。介绍了几种外科手术，包括前,后部,或组合方法。采用器械融合的椎板切除术是通过后入路使用的最受欢迎的手术。一个32岁的肥胖女人,患有背部疼痛和双下肢无力一个月，被转诊到我们的脊柱门诊。成像显示下胸部OPLL(T7/T8&T8/T9&T9/T10)。后纵韧带具有混合的骨化模式（喙状和持续的圆柱形）。为了保持胸椎的稳定性，防止未来的脊柱后凸，我们进行了椎板切除术和长段固定（T7至T12）。术后神经系统检查显示，肌肉力量显着增加，疼痛明显减轻。
