Background. Fractures of the odontoid peg are one of the commonest cervical spinal injuries in the elderly population. In this population there is a higher risk of morbidity and mortality as a result of the injury. The magnitude of the mortality risk has not been quantified in the literature. Aim. To show a survivorship analysis in a cohort of elderly patients with odontoid peg fractures. Method & Materials. A 6-year retrospective analysis was performed on all patients >65 years old with isolated odontoid peg fracture. Kaplan-Meir curve was used to estimate survivorship from the date of fracture. Results. A total of 32 patients witha mean age of 82.1 years were analysed. There were 17 male and 15 female with an average follow-up of 20.4 months. A low velocity mechanical fall was the commonest cause for the injury in 93.7% of cases. 81% of cases were treated with rigid collar immobilsation. Overall, it was estimated that only 62.5 % would be alive by one year. The period of greatest mortality was within the first 12 weeks, a lesser contribution from then to one year, and had no impact on mortality thereafter. Multivariate logistic regression demonstrated that age (P= 0.02) was significant factor with an odds ratio of 1.2. There was no significant relationship among gender or treatment with the occurrence of an adverse event. Conclusion. We observed a 3 month and one year mortality rates of 255 and 37.5% respectively. Odontoid peg fractures in the elderly are not benign injuries and are a cause of high mortality rates within the first three months of the injury. Patients who survived to one year following the injury were observed to have their risk return to age and sex matched rates for this population

Odontoid synchondral fractures are considered the most common type of fracture, amounting TO 10% of all subaxial injuries in the under 7 demographic. This injury occurs as typically the result of hyperflexion. Most odontoid fractures in children below 7 years of age involves the odontoid synchondrosis. The following is a report of the management of paediatric synchondral fractures in 2 patients who presented to the Children's Hospital Westmead in 2010. Both patients had displaced synchondral odontoid fractures which were managed by indirect reduction and halo traction. In both patients an anatomical alignment was achieved and maintained. Follow-up was 6 and 9 months respectively and the patients were assessed both clinically and radiologically. We feel the use of the “double mattress” technique is a valuable tool, as a means of achieving and maintaining occipitocervical extension, necessary, in the treatment of odontoid synchondral fractures

The aim of this paper was to present the clinical features of patients with musculoskeletal sources of methicillin-sensitive Staphylococcus aureus (MSSA) septicaemia.
