A rare case of atlantoaxial rotatory subluxation occurred after pediatric cervical spine surgery performed to remove a dumbbell-shaped meningioma at the level of the C1/C2 vertebrae. This case is classified as a post-surgical atlantoaxial rotatory subluxation, but has a very rare morphology that has not previously been reported. Although there are several reports about post-surgical atlantoaxia...

BACKGROUND Rheumatoid arthritis (RA) can have very destructive effects, especially in the cervical spine. Bone quality is poor in these patients. The purpose of this study is to evaluate the feasibility of fusion and accuracy of fluoroscopy in cervical transpedicular fixation (CPF) in a standardized clinical protocol for RA patients. MATERIALS AND METHODS 96 pedicles of 15 patients operated b...

Forty-one patients with rheumatoid arthritis involving the cervical spine had a posterior cervical arthrodesis. They were followed for a minimum period of seven years. The diagnoses prior to surgery included cranial settling, atlantoaxial subluxation, subaxial subluxation, and any combination of these three. All patients had posterior arthrodesis, with or without methylmethacrylate, and iliac c...

OBJECTIVE To describe cervical spine abnormalities in a group of adult patients with refractory juvenile chronic arthritis (JCA) complicated by secondary amyloidosis (SA). METHODS The series consists of 49 patients who fulfilled the diagnostic criteria of the European League Against Rheumatism for JCA, here complicated by secondary amyloidosis (SA). We evaluated their clinical records and mos...

THE JOURNAL OF BONE AND JOINT SURGERY tions, including 24-hour ambulant monitoring, revealed only atrial fibrillation. Radiographs of the cervical spine showed spondylolisthesis at the C5 to C6 level. Anterior cervical interbody fusion was performed at this level; the bony changes seen at operation were similar to those described in case 1. He had no more drop attacks during the last year of hi...

Degenerative cervical spondylolisthesis (DCS) had previously been thought to be a rare condition when compared to degenerative lumbar spondylolisthesis. However, with consequences from untreated spondylolisthesis including pain, myelopathy, and radiculopathy, it has now become recognized as an under-studied condition which may be more prevalent than previously thought. Spondylolisthesis of the ...

Here we report a unique case of bilateral ganglion cysts originating from the ligamentum flavum in the cervical spine. Degenerative cysts of the ligamentum flavum are rare lesions, and most had been reported in the lumbar spine. Its occurrence in the cervical spine is extremely rare: only eight have been reported. A 66-year-old male patient presented with progressive paraparesis, pain, and pare...

The authors present a case of a 44 year old healthy pregnant (with twins) female diagnosed with Mycobacterium xenopi in her lung. A mass was incidentally noted in the right upper apex on an MRI ordered to evaluate a subluxation seen in her cervical spine appreciated on plain radiography. Mycobacterium xenopi is uncommon, especially in immunocompetent patients. The patient did have a fractured a...

OBJECTIVE The objective of this study was to estimate the sensitivity of plain radiographs in identifying bony or ligamentous cervical spine injury in children. METHODS We identified a retrospective cohort of children younger than 16 years with blunt trauma-related bony or ligamentous cervical spine injury evaluated between 2000 and 2004 at 1 of 17 hospitals participating in the Pediatric Eme...

The aim of this case report was to highlight the application of magnetic resonance imaging (MRI) in elucidating serious and occult injuries in a single case of hyperflextion injury of a patient cervical spine (C-Spine). A chart and radiology review was performed to establish the sequence of care and how the results of imaging studies influenced the clinical management in this trauma case. Plain...
