“…These have been attributed to the disruption of the paravertebral muscles and the integrity of the "SP-ligament-muscle complex" [14]. These symptoms are thought to be closely related to the detachment of muscles in the C2 to C7 region, damage to the integrity of the nuchal ligament, and facet joint injury [15,16]. In the present study, the exion-extension lateral lms (pre versus post-operative) did not manifest instability (> 2 mm in the sagittal plane of two adjacent vertebral bodies)…”

Background Cervical spondylotic myelopathy (CSM) caused by multi-segment cervical stenosis is a common spinal surgery disease with severe neurological dysfunction. The surgical goal was to achieve full canal decompression while minimizing damage to the normal structures. Unilateral biportal endoscopy (UBE), due to its good visualization, independent view-working portals, and wider instrument availability, can be utilized to efficiently and safely complete a laminectomy under endoscopy. Objective This study was to determine the efficiency and safety of a novel cervical laminectomy technique and introduce some new endoscopic anatomic concepts. Methods We report on 3 cases of multi-segment of cervical stenosis. The author attempted combinations of "laminectomy", "hemilaminectomy", and "ligamentum flavum resection" under UBE for different cervical cases. The postoperative neurological improvement and perioperative complications were used to determine the efficiency and safety. Results All 3 patients got significant improvement after surgery. And no complication was observed. This study described in detail the surgical steps and introduced new anatomic concepts that "infraspinous absence range (IS-AR)" and "ligamentum flavum-interspinous space (LF-IS space)". Conclusion Central laminectomy for bilateral decompression (CLBD) under UBE is an effective surgical method for the treatment of CSM caused by multi-segment cervical spinal stenosis. It can achieve the same decompression effect as traditional open cervical laminectomy while protecting the paraspinal muscles and posterior ligament complex which can avoid postoperative axial symptoms and cervical stiffness. However, due to the small size of the spinal canal and the small perturbation tolerance of the cervical spinal cord, the learning curve will be slightly high.

“…4,50,51 The symptoms are thought to arise from facet joint injury, deep extensor muscle denervation, detachment of muscles at C2 and/or C7, detachment of the nuchal ligament, and prolonged postoperative external immobilization. 52 Anterolisthesis has also been shown to be a significant predictor of persistent axial neck pain following laminoplasty. 53 Patients without diffuse or generalized axial neck pain as a predominant complaint preoperatively were shown to have a significant improvement in NDI following laminoplasty.…”

“…There is some evidence that axial neck pain and stiffness may persist after laminoplasty with an incidence reported between 6% and 80%, and is therefore typically avoided in patients who report significant neck discomfort preoperatively 4,50,51. The symptoms are thought to arise from facet joint injury, deep extensor muscle denervation, detachment of muscles at C2 and/or C7, detachment of the nuchal ligament, and prolonged postoperative external immobilization 52. Anterolisthesis has also been shown to be a significant predictor of persistent axial neck pain following laminoplasty 53.…”

Objective: The aim was to discuss current methods and review updated outcome studies regarding posterior decompression in the management of cervical myelopathy.Summary of Background Data: Progressive myelopathy in the cervical segments is an indication for urgent surgical management. Although nonoperative treatment is an option in mild to moderate cases, the majority of patients will experience deterioration in neurological function requiring surgical decompression.Methods: A review of the literature was performed using PubMed to provide updated information regarding posterior cervical decompression in the management of myelopathy.Results: There are numerous studies comparing outcome data between cervical laminectomy and fusion with laminoplasty. While each technique has advantages and disadvantages, both provide adequate decompression and good long-term outcomes in patients meeting appropriate criteria.Conclusions: Posterior decompression is an important approach for spine surgeons to have in their toolkits when treating cervical myelopathy.
