Purpose. The treatment of C2 fractures with collar, halo or surgery can all be justified depending on the patient. In our unit, primary treatment is with a halo: in a previous study presented at BASS we found an 85% fusion rate. In a follow on study, we wished to assess the outcome in those patients who underwent surgical treatment. Methods. The discharge logbook was examined retrospectively to identify patients who had posterior instrumentation for C2 fractures from 2008-2010 inclusive. Discharge summaries, clinic letters and radiology images/reports from PACS were analysed to obtain data regarding primary treatment, outcome, necessity for delayed treatment and radiological evidence of union. Results. Seven patients were identified who had surgery for C2 fracture. All 7 patients were treated with C1 and C2 lateral mass screws. In two of these patients additional lateral mass screws were inserted at C3. Due to patient preference, three of the seven patients underwent operative fixation without prior treatment in a halo. All three patients had evidence of bony union at the fracture site on subsequent radiological follow up. The remaining four patients were initially treated in a halo and had delayed surgery. After surgery two of these four patients had radiological evidence of bony union at the fracture site, one remained non-united and one patient has not yet been fully assessed. Conclusions. In this small series, operative fixation for C2 fracture lead to bony union at the fracture site in 5 out of 6 cases where full follow up was available. Interestingly, bony union at the fracture site may be an achievable objective even when surgery has been delayed or is not the primary treatment

We have reviewed 81 patients with fractures of the odontoid process treated between May 1983 and July 1997, by anterior screw fixation. There were 29 patients with Anderson and D’Alonzo type-II fractures and 52 with type III. Roy-Camille’s classification identified the direction and instability of the fracture. Operative fixation was carried out on 48 men and 33 women with a mean age of 57 years. Associated injuries of the cervical spine were present in 15 patients, neurological signs in 13, and 18 had an Injury Severity Score of more than 15. Nine patients died and 11 were lost to follow-up. Of 61 patients, 56 (92%) achieved bony union at an average of 14.1 weeks. Two patients required a secondary posterior fusion after failure of the index operation. A full range of movement was restored in 43 patients; only six had a limitation of movement greater than 25%. We conclude that anterior screw fixation is effective and practicable in the treatment of fractures of the dens

Fractures of the odontoid peg are common spinal injuries in the elderly. This study compares the survivorship of a cohort of elderly patients with an isolated fracture of the odontoid peg versus that of patients who have sustained a fracture of the hip or wrist. A six-year retrospective analysis was performed on all patients aged > 65 years who were admitted to our spinal unit with an isolated fracture of the odontoid peg. A Kaplan–Meier table was used to analyse survivorship from the date of fracture, which was compared with the survivorship of similar age-matched cohorts of 702 consecutive patients with a fracture of the hip and 221 consecutive patients with a fracture of the wrist.

A total of 32 patients with an isolated odontoid fracture were identified. The rate of mortality was 37.5% (n = 12) at one year. The period of greatest mortality was within the first 12 weeks. Time made a lesser contribution from then to one year, and there was no impact of time on the rate of mortality thereafter. The rate of mortality at one year was 41.2% for male patients (7 of 17) compared with 33.3% for females (5 of 15).

The rate of mortality at one year was 32% (225 of 702) for patients with a fracture of the hip and 4% (9 of 221) for those with a fracture of the wrist. There was no statistically significant difference in the rate of mortality following a hip fracture and an odontoid peg fracture (p = 0.95). However, the survivorship of the wrist fracture group was much better than that of the odontoid peg fracture group (p < 0.001). Thus, a fracture of the odontoid peg in the elderly is not a benign injury and is associated with a high rate of mortality, especially in the first three months after the injury.
