Introduction and Aims: The aim of this paper is to review C1-C2 facet screw use in paediatric patients and to demonstrate that the technique plays an important role in patients with underlying anatomic abnormalities, which are common in children with cervical instability. Method: A chart review was conducted of all patients managed with C1-C2 facet screws from January 1, 1996 until July 30, 2003 present in the case database. All radiographs were obtained and reviewed. Post-operative and follow-up films were assessed for acceptable screw position and evidence of fusion. Results: C1-C2 facet screws were utilised in nine patients at British Columbia’s Children’s Hospital. The youngest patient treated was five years of age with a mean age for the group of 12. The group consisted of three Down syndrome patients and six with Os Odontoidium, two of which failed previous C1-C2 fusion. Two patients presented with an acute spinal cord injury. Pre-operative CT or MR imaging was used in all patients. Screw placement was unacceptable in one case. Post-operative
Radiographic follow-up of traumatic spondylolisthesis of the axis is well documented in the literature. However, there is a paucity of studies regarding the long-term functional outcome of this type of injury. To study the population, treatment and outcome following traumatic spondylolisthesis of the axis, we reviewed 36 consecutive patients presenting to our institution, a tertiary referral spinal trauma centre, over a 6-year period. We assessed: (a) the mechanism of injury, (b) the mode of treatment, (c) the radiographic classification using the Levine and Edwards system and (d) functional outcome using the Cervical Spine Outcomes Questionnaire (CSOQ) by BenDebba. Of the 36 patients presenting there were 24 males and 12 females with a mean age of 46 (range18-82) years. The commonest mechanism of injury was road traffic accidents. There were 14 Type-I, 11 Type-II and 1 Type-IIA fractures. Twenty-seven patients were treated with
The aim of this study was to assess the use of early ambulatory halo-thoracic immobilisation in paediatric patients with spinal instability. The case notes, radiographs and clinical findings at follow-up of 12 patients treated this way were reviewed. The mean age was 8.6 years (4 to 16). The aetiology was trauma in six, os odontoidium in one, tuberculosis in three, and Morquios syndrome and chronic granulomatous osteitis in one each. The instabilities were atlanto-axial rotatory subluxation in one patient, transverse ligament rupture in six, dens anomalies in two, anterior destruction by tuberculosis in two, and a dens fracture. The halo jackets were applied under general anaesthetic. In addition, posterior C1/2 fusions were performed in seven patients, posterior occipitocervical decompression and fusions in two, and posterolateral thoracotomies in two. No surgery was done on the patient with the dens fracture. Autograft was used in all cases except one posterior C1/2 fusion. This patient, who was HIV-positive, was the only one in whom union did not occur. There was one case of minor pin-tract sepsis. All patients mobilised in the halo jacket and, where possible, were managed as outpatients. Despite radiological nonunion in one patient, spinal stability was achieved in all. Early ambulatory
