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
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.
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 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. Cite this article:
