Odontoid fractures were classified by Anderson and D'Alonzo in 1974. Out of the three types, type II is the most frequent, and there are various approaches described for their surgical fixation, where it is indicated. Posterior C1-C2 fusion is a very versatile approach u...
关于此类骨折的治疗应严格遵从稳定压倒一切的原则,先牵引复位,后固定治疗。 医博士编译自:Minyu Z, Shiyang W, Suraj C, et al. Traumatic postero-lateral C1-C2 dislocation complicated with locked lateral mass and type II odontoid fracture - a 5-year follow-up: A case report. World Neurosurgery. 201...
We sought to evaluate the long-term C1-C2 fusion rates, fracture healing, and functional outcomes in geriatric patients with type II odontoid fracture treated with posterior fixation with polyaxial C1 lateral mass screws and C2 pars screws. Methods Twenty-one consecutive patients between 2005 and ...
In addition, the C2 vertebra has a unique anatomical structure with the odontoid process, which can complicate the surgical approach and implant placement. Additionally, it has been noted that the raised edge of the plate has a tendency to exacerbate irritation to the soft tissues of the pharynx...
Pertinent literature exists concerning indications, techniques, complications of treatment, and risk factors for nonunion in axis and odontoid fractures; however, there are scarce data regarding the incidence and definition of malunion in these fractures. As a prerequisite for the study of anatomical ...

In this unique report, we present for the first time the use of a fusionless occipitocervical operation for the treatment of a type II odontoid fracture and unilateral C2 pars fracture adjacent to a previous C2-pelvis posterior instrumented fusion. METHODS: Case report. RESULTS: Three years ...
Methods All cases of anterior odontoid screw fixation between 2010 to 2020 were retrospectively analysed. Patients' clinical, radiological (type of fracture, orientation, displacement and diastasis), operative (single vs double screw) and follow-up records were documented. The post-operative imaging ...
Clinical Presentation: Our case, after AITC, with Levin Edwards Type 1A Hangman fracture, A 40-year-old female patient with no neurological deficits. The patient does not prefer to use a halo orthosis C2 transpedicular surgery was performed with a lag screw for motion-sparing surgery to...
