BACKGROUND: In multilevel degenerative conditions posterior approaches are often preferred, but anterior approaches provide comparable clinical results and better alignment. Anterior plating entails higher rates of soft tissue injuries and dysphagia, particularly in multilevel cases. This study evaluates efficacy and safety of zero-profile devices in three and four-level ACDF, analyzing patients' clinical and radiological long-term outcome. METHODS: We prospectively enrolled 24 patients with cervical spondylotic myeloradiculopathy (CSM), who underwent three and four-level ACDF with Zero-P device...

INTRODUCTION: The laminoplasty has been the most widely used surgical method for OPLL. In recent years, increasing attention has been drawn to the anterior operative approaches for surgical treatment of cervical OPLL. However, which method is the optimum selection for therapy of cervical OPLL is still obscure. Therefore, we performed this prospective nonrandomized clinical studyin patients with multilevelcervical myelopathydue to OPLL and compare thetherapeutic efficiencyof laminoplastyand anterior approach (cervical discectomy and/or cervicalcorpectomy) in the management of multi-level cervical OPLL...

OBJECTIVE: Cervicogenic headache affects a significant portion of the entire population. This type of headache especially with atypical presentation is often hard to diagnose and manage since its etiopathophysiology is not been yet well understood. We have investigated the prevalence of cervicogenic headache with atypical presentation and discussed the etiology of it, and the outcome of surgical intervention on this type of headache in patients with cervical degenerative disease. PATIENTS AND METHODS: Radiological and clinical data of 160 patients (from 2001 through 2016) were retrospectively reviewed...

BACKGROUD: Anterior cervical discectomy and fusion (ACDF) with plate-screw construct has been gradually applied for multilevel cervical spondylotic myelopathy (CSM) in recent years. However, long cervical plate was associated with complications including breakage or loosening of plate and screws, trachea-esophageal injury, neurovascular injury, and postoperative dysphagia. To reduce these complications, the zero-profile spacer has been introduced. This meta-analysis was performed to compared the clinical and radiological outcomes of zero-profile spacer versus cage-plate construct for the treatment of multilevel cervical spondylotic myelopathy...
