Whiplash injury is surrounded by controversy in both the medical and legal world. The debate on whether it is either a potentially serious medical condition or a social problem is ongoing. This paper briefly examines a selection of studies on low velocity whiplash injury (LVWI) and whiplash associated disorder (WAD) and touches upon the pathophysiological and epidemiological considerations, cultural and geographical differences and the effect of litigation on chronicity. The study concludes that the evidence for significant physical injury after LVWI is poor, and if significant disability is present after such injury, it will have to be explained in terms of psychosocial factors

Background. Fractures of the odontoid peg are one of the commonest 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 this 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 and Materials. A 6-year retrospective analysis was performed on all patients >65 years old admitted to a spinal unit with an isolated odontoid peg fracture. Actuarial (Life-Table) analysis was used to estimate survivorship from the date of fracture. Results. A total of 32 patients > 65 years of age with isolated odontoid peg fractures were identified. There were 17 male and 15 female. A low velocity mechanical fall was the commonest cause for the injury. The average age for the females was 86.7 years and for the males 78 years. The age distribution was unimodal in both sex, the greatest number occurring for the females in the 85-94 year age group and 75-84 years for the males. 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. Males appeared to suffer a heavier mortality than females within the first year. At one year the male survival rate had fallen to 58.8% compared with a female rate of 66.6%. Conclusion. We observed that 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

Royal Liverpool University Hospital, Liverpool, UK. To retrospectively review outcomes in patients who underwent vertebroplasty in Liverpool in response to recent level 1 publications claiming vertebroplasty to be no better than sham procedure assessed using 2 criteria. We reviewed cases between 2006 and 2009 looking at 5 criteria for procedure. Visual Analogue Score (VAS). Oswestry disability index scores (ODI). 96 patients identified. 10 patients excluded (inadequate data recorded) (n=86). Operated levels n=134 (thoracic n=61, lumbar n=71, sacral n=2). Presenting symptoms included back pain (86/86) and point tenderness was present in 90% (77/86). Average length of symptoms was 11.50 months with 28% reporting greater than 12 months. 72% recalled definite onset of symptoms with 90% being associated with a low velocity injury. Radiological findings showed an average of 54% height collapse and 91% showing high signal on STIR MRI sequences. Number of levels operated – 3 or more (n=9 VAS 5.3 ODI 10.6); 1 to 2 levels (n= 77 VAS 3.7 ODI 13.9). Average improvement in VAS score was 3.8.and ODI 13.6. 47% (40/86) of patients met all 5 current criteria recommended for operation (VAS 3.7, ODI 14). 53% (46/86) of patients met 2-5 criteria (VAS 3.8, ODI 13.4). There was improvement in pain scores in 91% of patients with an average pre-op VAS 7.8 and post-op VAS 4.0. There was no significant difference in patients meeting all 5 criteria compared to those meeting 2-5 criteria
