Surgical treatment of upper cervical spine tumors, whether they are vertebral, epidural, subdural or intramedullary, raises technical and decisional difficulties regarding the approach of the region as well as in maintaining its stability. The authors performed a retrospective study on C1, C2 spinal tumor pathology, managed surgically in the Spinal Surgery Department of Bagdasar Arseni Clinical...

BACKGROUND Anterior cervical discectomy and fusion (ACDF) has become a common procedure for cervical spine surgeries, since it is safe and effective in most patients. However, some patients develop life-threatening problems such as respiratory obstruction arising from rare postoperative hematoma and edema, although intraoperative bleeding caused by the connective tissue splitting procedure or b...

The cervical spine is one of the most complex structures of the human skeleton. The knowledge of the cervical spine kinematics is a very important tool for many clinical applications such as diagnosis, treatment and surgical interventions and for the development of new spinal implants. The finite element method (FEM) is a well-known and widely used numerical method to simulate structural behavi...

PURPOSE Pedicle screw fixation in the upper cervical spine is a difficult and high-risk procedure. The screw is difficult to place rapidly and accurately, and can lead to serious injury of spinal cord or vertebral artery. The aim of this study was to design an individualized 3D printing navigation template for pedicle screw fixation in the upper cervical spine. METHODS Using CT thin slices da...

Cervical spine disorders which can cause swallowing difficulties (cervicogenic dysphagia; CD) are: chronic multisegmental/MS dysfunction (dysfunction=functional blockade) of the facet joints, changes in physiological curvature of the cervical spine, degenerative changes (anterior osteophytes, anterior disc herniation, osteochondrosis, osteoarthritis), inflammatory rheumatic diseases, diffuse id...

Although laminar screw fixation is often used at the C2 and C7 levels, only few previous case reports have presented the use of laminar screws at the C3-C6 levels. Here, we report a novel fixation method involving the use of practical laminar screws in the subaxial spine. We used laminar screws in the subaxial cervical spine in two cases to prevent vertebral artery injury and in one case to min...

OBJECTIVE To investigate the incidence of C5 nerve root palsy after multi-segmental cervical decompression through different approaches. METHODS This study was conducted among 375 patients undergoing multi-segmental cervical decompression in anterior corpectomy and fusion fixation, anterior cervical corpectomy and fusion fixation + posterior decompression and fusion fixation, posterior cervic...

AIM In unique clinical situations where C1-C2 posterior fixation is not available or has previously failed, an anterior transarticular screw (ATAS) may be a viable alternative. However, there are no previous reports that investigate possible screw angles, screw entry points, and screw length based on computed tomography (CT) multiplanar reconstruction images in Turkish patients. The aim of this...

STUDY DESIGN Retrospective, cross-sectional study. OBJECTIVE To evaluate the feasibility of two screws anterior fixation of the odontoid process among Arab adults. SUMMARY OF BACKGROUND DATA Anterior screw fixation is the treatment of choice for type II odontoid fractures. In order to perform the procedure safely, the diameter of the odontoid process should be wide enough to allow for the p...
