Grisel syndrome is a condition of uncertain etiology characterized by a non-traumatic atlantoaxial subluxation following an infection in the head and neck region. Although first described in 1830, the exact pathophysiology of Grisel syndrome remains unclear. We present a case of atlantoaxial subluxation after acute lymphadenitis diagnosed with a dynamic computed tomography (CT) and magnetic res...

We report a case of 64-year-old Tunisian woman with a 12-year history of rheumatoid arthritis, who presented with a 3-month history of increasing inflammatory neck pain. Neurological examination noted a quadripyramidal syndrome without any neurological deficit. Radiographs of her neck showed ananterior atlantoaxial subluxation (A). MRI revealed a pannus around the atlanto axial joint. It also s...

BACKGROUND Chiropractors claim to locate, analyze and diagnose a putative spinal lesion known as subluxation and apply the mode of spinal manipulation (adjustment) for the correction of this lesion. AIM The purpose of this examination is to review the current evidence on the epidemiology of the subluxation construct and to evaluate the subluxation by applying epidemiologic criteria for it's s...

OBJECTIVE This commentary describes the debate and some of the associated issues involving the subluxation construct. DISCUSSION The long-standing debate regarding the chiropractic subluxation has created substantial controversy within the profession. Currently, this phenomenon can be compared with a country with a 2-party system that has a large silent majority sitting between the 2 factions...

BACKGROUND AND PURPOSE The ADI is the imaging diagnostic clue to AAA subluxation of the cervical spine. Some MR imaging findings other than abnormal ADI relate to AAA subluxation. However, their relationship is not yet clarified. The present study elucidates the role of MR imaging by employing these previously overlooked findings. MATERIALS AND METHODS This study enrolled 40 patients with AAA...

OBJECTIVE This study aimed to compare the clinical and radiologic outcomes of patients with subaxial cervical injury who underwent anterior cervical discectomy and fusion (ACDF) with autologous iliac bone graft or polyetheretherketone (PEEK) cages using demineralized bone matrix (DBM). METHODS From January 2005 to December 2010, 70 patients who underwent one-level ACDF with plate fixation for...

Introduction : Closed reduction is widely accepted as the initial management of subaxial facet dislocation. However, there a substantial risk neurological deterioration due to herniated discs or fractured vertebral bodies during procedure. Recently, it has been reported that open and fixation via an anterior approach for dislocation had good outcomes. some cases with locked facets were difficul...
