To describe reciprocal changes in cervical alignment after adult spinal deformity (ASD) correction and subsequent development of proximal junctional kyphosis (PJK). This study also investigated these changes using two novel global sagittal angular parameters, cervical-thoracic pelvic angle (CTPA) and the T1 pelvic angle (TPA). ⋯ The prevalence of PJK was 29 % at 1 year follow-up. CTPA, which correlates with CPL as a global analog of cervical sagittal balance, and TPA describe relative proportions of cervical and thoracolumbar deformities. Patients who develop PJK in the upper thoracic spine after thoracolumbar 3CO also develop concomitant cervical sagittal deformity, with increases in CPL and CTPA.

Randomized Controlled Trial
A prospective randomized trial comparing anterior cervical discectomy and fusion versus plate-only open-door laminoplasty for the treatment of spinal stenosis in degenerative diseases.
For three or more involved cervical levels, there is a debate over which approach yields the best outcomes for the treatment of multilevel cervical degenerative disease. Our objective is to compare the radiological and clinical outcomes of two treatments for multilevel cervical degenerative disease: anterior cervical discectomy and fusion (ACDF) versus plate-only open-door laminoplasty (laminoplasty). ⋯ Both ACDF and laminoplasty are effective and safe treatments for multilevel cervical degenerative disease. ACDF causes fewer traumas than laminoplasty.

To identify whether expansive open-door laminoplasty (Lam) is more appropriate than laminectomy and instrumented fusion (LIF) for cases with ossification of the posterior longitudinal ligament (OPLL) and straight cervical lordosis. ⋯ When compared with the LIF, the Lam is recommended for cases with OPLL and straight cervical lordosis when taking comparable neurological recovery, less axial pain and better neck function improvement into consideration.
-
To determine whether radiological, clinical, and demographic findings in patients with cervical spondylotic myelopathy (CSM) were independently associated with loss of cervical lordosis (LCL) after laminoplasty. ⋯ Cervical alignment was compromised after laminoplasty in patients with CSM, and the degree of LCL was associated with preoperative T1 slope, C2-7 SVA, and CVLL.
-
To investigate a unique procedure of joined transoral and retropharyngeal high cervical approach (JTRC) without mandibulectomy for treating upper cervical neoplasm involving both C2 and C3. ⋯ The JTRC approach could provide good surgical exposure for treating disorders involving both upper and lower cervical spine without splitting up the mandible.
