Aims

Rates of mortality as high as 25% to 30% have been described following fractures of the odontoid in the elderly population. The aim of this study was to examine whether easily identifiable variables present on admission are associated with mortality.

Patients and Methods

A consecutive series of 83 elderly patients with a fracture of the odontoid following a low-impact injury was identified retrospectively. Data that were collected included demographics, past medical history and the results of blood tests on admission. Radiological investigations were used to assess the Anderson and D’Alonzo classification and displacement of the fracture. The mean age was 82.9 years (65 to 101). Most patients (66; 79.5%) had a type 2 fracture. An associated neurological deficit was present in 11 (13.3%). All were treated conservatively; 80 (96.4%) with a hard collar and three (3.6%) with halo vest immobilisation.

Aims. We performed a retrospective, comparative study of elderly patients with an increased risk from anaesthesia who had undergone either anterior screw fixation (ASF) or halo vest immobilisation (HVI) for a type II odontoid fracture. Patients and Methods. A total of 80 patients aged 65 years or more who had undergone either ASF or HVI for a type II odontoid fracture between 1988 and 2013 were reviewed. There were 47 women and 33 men with a mean age of 73 (65 to 96; standard deviation 7). All had an American Society of Anesthesiologists score of 2 or more. Results. Patients who underwent ASF had a significantly better outcome than those who were treated by HVI. There was a rate of nonunion of 10% after ASF and 23% after HVI. Failure of reduction or fixation occurred in 11 patients (15%) but there was no significant difference between the two groups. Mortality rates were also similar: 9% (n = 3) after ASF and 8% (n = 4) after HVI. Conclusion. We conclude that ASF is the preferred method of treatment in this group of elderly patients, having a significantly higher rate of fusion, better clinical outcome and a similar rate of general and treatment-related complications.

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 halo vest immobilisation and nine were immobilised in a Minerva jacket. Four patients were converted from halo to Minerva because of pin failure. The mean duration of hospital stay was 10 (range 3-30) days. All fractures demonstrated radiographic union at a mean of 12 (range 10-16) weeks. There were no neurological complications. Upon review, all patients, whether Type-I or Type-II demonstrated low CSOQ scores approaching their pre-morbid status. However, Type-II fractures scored higher in 3 functional outcome categories when compared to Type-I fractures. This unique study of an uncommon fracture shows for the first time a difference in the functional outcome scores of Type-II fractures of the axis when compared to Type-I fractures at a mean follow-up of 3 years and 10 months

We evaluated the efficacy of anterior fusion alone compared with combined anterior and posterior fusion for the treatment of degenerative cervical kyphosis. Anterior fusion alone was undertaken in 15 patients (group A) and combined anterior and posterior fusion was carried out in a further 15 (group B). The degree and maintenance of the angle of correction, the incidence of graft subsidence, degeneration at adjacent levels and the rate of fusion were assessed radiologically and clinically and the rate of complications recorded. The mean angle of correction in group B was significantly higher than in group A (p = 0.0009). The mean visual analogue scale and the neck disability index in group B was better than in group A (p = 0.043, 0.0006). The mean operation time and the blood loss in B were greater than in group A (p < 0.0001, 0.037). Pseudarthrosis, subsidence of the cage, and problems related to the hardware were more prevalent in group A than in group B (p = 0.034, 0.025, 0.013).

Although the combined procedure resulted in a longer operating time and greater blood loss than with anterior fusion alone, our results suggest that for the treatment of degenerative cervical kyphosis the combined approach leads to better maintenance of sagittal alignment, a higher rate of fusion, a lower incidence of complications and a better clinical outcome.

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 halo jacket immobilisation is a useful, safe and well-tolerated technique in the paediatric patient group

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 Halo immobilisation was used in seven patients. Post-operative complications included one wound infection and four halo pin infections requiring treatment. No patients have required surgery at a mean follow-up of four years. C1-C2 facet screws are an important adjunct in a paediatric spine practice. This technique has a great advantage in Down syndrome patients who have a high rate of pseudoarthosis because of: ligamentous laxity, non-compliance with immobilisation and a high incidence of congenital deformities such as os odontoidium and incomplete posterior arch of C1. Conclusion: C1-C2 facet screws can be safely used in young children. The screws allow for fixation in the absence of an intact posterior arch. The technique has a great advantage in Down syndrome patients who have a high rate of pseudoarthosis due to congenital deformities, ligamentous laxity and non-compliance with immobilisation
