Two ligaments contribute to the limitation of the spinal canal (Figure 1.46): The posterior longitudinal ligament, anteriorly, covers the dorsal aspect of vertebral bodies and intervertebral disks.The ligamentum flavum, posteriorly, is tightly adherent to the vertebral laminae. This ligament is an essential landmark for epidural and spinal anesthesias.

Thoracic ossification of the posterior longitudinal ligament (TOPLL) is a common disease middle-aged with a reported incidence of 0.44% to 8.92% in Chinses population [1]. The widely proliferative posterior longitudinal ligament could compresses the spinal cord and/or nerve root due to, resulting in sensory and motor disorders of the limbs and dysfunction of the visceral autonomic nervous system [2]. Its pathogenic mechanism is not precise but is most likely multifactorial, including age, sex, developmental malformation, genetic inheritance pattern and other factors. It is generally believed that it is caused by heterotopic ossification of chondrocytes. However, some scholars argue that it is related to fibrocartilage and intramembranous ossification, and that degenerative intervertebral disk can affect the formation of ossification of posterior longitudinal ligament [3,4].

Clinically, back pain VAS and RMDQ scores were more improved in the DIAM implantation group. Theoretically, maintaining intervertebral space height should help bring back to a more natural position and relieve more pain. Cadaveric studies showed that IPD distracted the rostral part of the functional spinal unit, repositioned and unloaded facet joints and reduced intervertebral pressure, especially on the rostral part of endplates.15 Distraction of the spinous processes can relieve the load from the rostral part of the intervertebral disc and diminish the axial pressure across the endplates. It may stretch the posterior longitudinal ligament and the annulus fibrosus into more natural positions, thus, improving their capacity to resist loading stress.28 Pain relief and normal posture maintenance might have positive effects on many aspects of patients’ disability, including walking, sitting, sleeping and so on. In our study, disc height narrowing was associated with back pain and progression of spondylolisthesis was associated with leg pain and disability in correlation analysis. DIAM implantation was associated with change of dis height, spondylolisthesis by distraction and fixation. It could slow down disc height narrowing and slippage of adjacent segment. Also, it could improve pain and disability.
Relationship Between Sagittal Balance and Axial Symptoms in Patients with Cervical Spondylotic Myelopathy Treated with Anterior Cervical Discectomy and Fusion

Anterior cervical discectomy and fusion (ACDF) is a typical procedure used to treat cervical spondylotic myelopathy. However, after undergoing surgery, some patients suffer from axial symptoms, such as neck and shoulder pain or stiff neck [1]. Kawakami et al. [2] reported that axial symptoms can occur after anterior fusion, and the risk factors of axial symptoms are cervical kyphosis and loss of vertebral body height at the fused segment. The incidence of postoperative axial symptoms may be related to Modic changes, especially Modic 2 changes, in cervical segments [3]. Axial pain may be alleviated by resecting the posterior longitudinal ligament during anterior surgery [4]. Unfortunately, to date, the specific etiology of postoperative axial symptoms has yet to be clearly elucidated.
