To investigate the noninferiority of facet joint- and nuchal ligament-sparing laminectomy (FNL) compared with conventional open-door laminoplasty. ⋯ FNL was not inferior to conventional open-door laminoplasty in terms of clinical or radiologic outcomes, reducing the detachment of muscle from each lamina.

Case Reports
Late Cervical Spinal Cord Herniation Resulting from Post-Traumatic Brachial Plexus Avulsion Injury.
Spinal cord herniation (SCH) is often described as occurring spontaneously in the thoracic spine, with few cases of cervical SCH reported as a late complication of traumatic brachial plexus avulsion. We present 2 cases of nerve root avulsion and pseudomeningocele formation, resulting in delayed cervical SCH and neurologic deterioration. ⋯ SCH is a rare cause of delayed neurologic deterioration after brachial plexus avulsion, with few case reports describing its occurrence. We present 2 cases of this complication and describe its successful surgical treatment through dural repair after instrumented fusion.

Percutaneous transforaminal endoscopic diskectomy has been a major treatment for lumbar disk herniation. However, damage to exiting nerve roots is one of the most severe complications in this surgery. In this paper, the relationship of the exiting nerve root and the superior articular process in Kambin's triangle of the lumbar intervertebral foramen was assessed using cadavers and computed tomography (CT) imaging. ⋯ The bone-nerve space between the exiting nerve root and the superior articular process in Kambin's triangle of the lumbar intervertebral foramen was exceedingly narrow. It is necessary to perform a foraminoplasty to enlarge the working space and decrease the possibility of injury to the exiting nerve root.

To examine the preoperative patients with cervical spondylotic myelopathy (CSM): (1) whether cervical sagittal parameters are related to the progress of patients with CSM, and (2) whether cervical sagittal parameters can predict disease progression or prognosis in patients with CSM. ⋯ In preoperative patients with CSM, the larger CCI-CC is the only independent risk factor for the NDI increase. When the patient has a C2-C7 Cobb angle (F) > 29°, the patient's condition progresses slowly.
