“…[ 18 19 ] In other words, in the example given by Matsuoka, reducing the T1 slope angle corrects all spinopelvic parameters, and this is a controversial situation. [ 9 ] In such a patient, naturally, by performing lumbar or thoracic osteotomy, it will be a better choice for the improvement of cervical deformity. [ 20 21 22 ] In patients undergoing decompression and fusion due to cervical stenosis, it is very important to protect cervical parameters; otherwise, HRQOL can also cause serious disruption.…”

Objective: To monitor changes in cervical parameters before and after laminoplasty surgery. Cervical parameters and health-related quality-of-life (HRQOL) values that may be affected after laminoplasty were examined before and after surgery. The clinical and radiological course of these values was monitored, and their interaction with all spinal radiological parameters was revealed. Materials and Methods: Nineteen patients who underwent clinical and radiological evaluation for 2 years were followed in this study. Neck disability index, visual analog scale, and short form 36 scores were determined to evaluate HRQOL. For radiological parameters, the C0-C2 angle, C2-C7 angle, cervical sagittal vertical axis, T1 slope angle, neck tilt (NT) and thoracic inlet angle were used. The results of the 4-month, 1 year and 2-year follow-ups were statistically evaluated. Results: Both the HRQOL and cervical radiological parameters deteriorated in the first 4 months and returned to normal in the 2 nd year. Statistically, all parameters were meaningful ( P < 0.05), except for NT. Conclusion: Cervical parameters and HRQOL values, which deteriorated in the early period, recovered in the late period in the long-term follow-up of patients undergoing laminoplasty. The important point is that preoperative cervical parameters suitable for laminoplasty should be present, and spinopelvic parameters should be normal.

“…Inflammatory responses are known as a major component of secondary injury of initial ischemic insult and play an important role in modulating the pathogenesis of C5 palsy [37,8,24,20]. Effects of reperfusion, also known as reperfusion injury, are the causative factors for spinal edema [38,25,8,18]. The results of this study shown the complication of C5 palsy in PCDL were serve than ACCF may be related the spinal ischemia and reperfusion injury.…”

Background There are many factors that affect the C5 palsy in the treatment of cervical spondylosis myelopathy (CSM) with ossification of the posterior longitudinal ligament (OPLL), but the spinal compression degrees may be an important factor in affection on it. Objective The purpose of this study was to evaluate the effect of spinal cord compression degrees on the clinical outcomes of OPLL patients which been treated by anterior and posterior surgery. Methods From May 2010 to October 2017, 145 patients cervical spondylosis myelopathy with OPLL (spinal canal narrowing by the OPLL exceeded 30%) were enrolled in this study; 76 patients received anterior cervical corpectomy and fusion surgery (ACCF), and 69 patients had posterior cervical decompression and laminoplasty procedures (PCDL). The clinical outcomes of pain relief (visual analog scale, VAS), functional disability (neck disability index, NDI) were recorded at baseline and at the final follow-up. Results There were five patients with C5 palsy in this series cases (two in ACCF and three in PCDL), and the rate is 4.1% (3.2% in ACCF and 5.2% in PCDL, P > 0.05). Five C5 palsy cases had more than 50% compressed degrees of dural sac and flattened spinal cord, and the compressed dural sac and flattened spinal cord had totally expansion after operation. There were no patients resented with CSF leakage in PCDL group, and six patients presented with CSF leakage in ACCF. The mean postoperative canal diameter were significant better than preoperative in PDL patients (P < 0.01). The average spinal sagittal and axial compressive ratio were significantly decreased from preoperative in ACR and PDL groups (P < 0.01). The mean cervical ROM values were decreased in ACR and PDL groups (P< 0.05). Conclusions Based on the results of this study, anterior and posterior surgery was effective and safe in the treatment of the OPLL patients. The complication of C5 palsy were no related in the surgery methods, but may be related the degrees of spinal cord compressed.

“…To evaluate cervical sagittal balance, we measured the following parameters on cervical lateral X-ray: C2-7 SVA, T1 slope, CL, and T1 slope-CL. The C2-7 SVA was defined as the total distance from the plumb line of the pedicle center of the C2 vertebra to the posterior superior corner of the C7 vertebra [14]. The CL was measured using the Cobb angle of C2 lower endplate and C7 lower endplate [15].…”

Background Context. Cervical laminoplasty often gives rise to cervical sagittal imbalance attributable to injury of posterior structures including laminae, articular facets, muscles, and ligaments. Purpose. To determine the effect of age on sagittal cervical alignment after cervical laminoplasty procedure so as to identify the group with the greatest degree of variation. Study Setting. Single-center retrospective chart review in a tertiary referral hospital. Outcome Measures. The sagittal vertical axis (SVA) (C2-7), T1 slope, and cervical lordosis. Methods. We included patients who underwent cervical laminoplasty between 2014 and 2018 and divided 60 consecutive patients into two groups using the cut-off age of 65 years. The Paired t -test and Mann-Whitney U test were used to compare changes between preoperative radiographic cervical sagittal parameters and those 1 year after surgery. Results. Mean patient ages in the older and younger groups were 71 years and 52 years, respectively. The difference of C2-7 SVA was greater in the older group. Conclusion. Postoperative cervical balance can be worse when laminoplasty is performed in elderly patients.
