Atlantoaxial rotatory dislocation (AARD) is a rare complication in adults usually leading to pain, spinal cord injury, or death. Clinical and radiological diagnosis is difficult and often delayed. We report a rare case of posttraumatic AARD in a neurological intact 27-year-old male in which initial radiographic evaluation was negative. A computed tomography (CT) scan was promptly done because t...

Odontoid type I fracture is an avulsion fracture of the odontoid tip resulting from forceful distraction of the alar ligament and has been reported only in a few rare occasions. We have recently encountered an odontoid type I fracture complicated with atlantoaxial dislocation in an 18-year-old male motorcycle rider sustaining neck injury in a crash. An accurate diagnosis was achieved with axial...

It is known that cervical spine involvement occurs in over half of patients with rheumatoid arthritis (RA). This involvement is over 70% in Tunisia. The majority of our patients are seen at Ranawat’s stage III with spinal cord injury. We report a series of 28 patients treated in our institution for RA with atlantoaxial dislocation with several degrees of spinal cord injury (Ranawat’s stage II a...

Aim: To study the C1-2 facets in patients with congenital atlantoaxial dislocation and their bearing on the presentation and management. Materials and methods: Thirty-six patients of congenital AAD were studied in the last 2 years. Twenty-four patients had irreducible AAD (not reducing on traction) and remaining 12 had redu cible AAD. Computed tomography (CT) scans were obtained and the C1-2 jo...
