Os Odontoideum: Rare Cervical Lesion
We report the case of a 22-year-old Marine who presented to the emergency department, after a martial arts exercise, with transient weakness and numbness in all extremities. Computed tomography cervical spine radiographs revealed os odontoideum. Lateral flexion-extension radiographs identified atlanto-axillary instability. This abnormality is rare and can be career ending for military members w...
متن کاملOdontoideum Bone Revealed by c1-c2 Dislocation of the Cervical Spine during a Diving Accident
Introduction Odontoideum bone or the mobile odontoid process is one of the rarest malformations of the cervico-occipital hinge. It exposes to the atlo-axial instability and to the risk of bulbo-medullary compression threatening then the vital and functional prognosis. We report the case of a 16-year-old patient who was the victim of a raod accident resulting in acervical spine injury. Radiologi...
متن کاملComputer-assisted C1-C2 Transarticular Screw Fixation "Magerl Technique" for Atlantoaxial Instability
STUDY DESIGN A retrospective study. PURPOSE To evaluate the surgical results of computer-assisted C1-C2 transarticular screw fixation for atlantoaxial instability and the usefulness of the navigation system. OVERVIEW OF LITERATURE We used a computed tomography (CT)-based computer navigation system in planning and screw insertion in Magerl's procedure, which provides the most rigid atlantoax...
متن کاملMorphometric Characteristics of C1-C2 Vertebrae to Perform Anterior Transarticular Crossing Screw Fixation.
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...
متن کاملBiomechanical analysis comparing three C1-C2 transarticular screw salvaging fixation techniques.
STUDY DESIGN This is an in vitro biomechanical study. OBJECTIVE To compare the biomechanical stability of the 3 C1-C2 transarticular screw salvaging fixation techniques. SUMMARY AND BACKGROUND DATA Stabilization of the atlantoaxial complex is a challenging procedure because of its complicated anatomy. Many posterior stabilization techniques of the atlantoaxial complex have been developed wi...
