Lateral mass screw insertion (Magerl technique)
To identify the craniocaudal angulation, a Penfield elevator is inserted in the facet joint which will be included in the fusion. The drill trajectory is then parallel to this elevator, avoiding compromise of the facet joints. Alternatively, the trajectory of the facet joints may be …
Cervical Lateral Mass Fracture Separation - Spine - Orthobullets
Cervical Lateral Mass Fracture Separations of the lateral mass-facet are uncommon cervical spine injuries characterized by a high degree of instability and neurological deficits. Diagnosis is made with CT scan of the cervical spine.
Lateral Mass Fixation in Subaxial Cervical Spine: Anatomic ...
Lateral mass screw fixation has become the method of choice in stabilizing subaxial cervical spine among other posterior cervical fixation techniques whenever the posterior elements are absent or compromised.
Lateral Mass Screw Fixation in the Cervical Spine ...
Lateral mass screw fixation is a common surgery that is performed in the cervical spine. Various modifications for the procedure have been described, such as changes in the entry point, angulation of the screws, and modifications in the exit point.
Cervical spine injuries associated with lateral mass and ...
To clarify the injury pattern, initial spinal instability, degree of discoligamentous injuries in cervical lateral mass and facet joint fractures, we retrospectively analyzed radiological parameters and introduced a new classification for these injuries.
Lateral Mass Screws - Musculoskeletal Key
2019年7月9日 · Lateral mass screw–based instrumentation is a well-established technique for cervical spine fusion. Screw placement is constrained by the course of the vertebral artery, the nerve roots, and the anatomy of the facet joints.
Lateral Mass Screw Fixation in the Cervical Spine: A ...
1980年1月1日 · The purpose of this study is to describe the safety profile and effectiveness of lateral mass screw fixation (LMSF) when used for stabilization and fusion of the posterior cervical spine.
