Type II odontoid fractureAutofusionAnterior fusionThis case demonstrates that patients with inaccessible C2–3 disc spaces can still undergo anterior fixation. In younger patients, this may be particularly valuable as the rotatory potential of their cervical spine is preserved....
Ⅰ型Hangman骨折伴Ⅱ型齿状突骨折联合C2～3椎间盘损伤丧失了除寰枢关节旋转功能外C1～ C3节段所有方向的稳定性.本研究可为相关内固定技术的研究和临床治疗提供生物力学依据.%Objective To evaluate the effect of type Ⅱ odontoid fracture,type Ⅰ Hangman fracture,C2-C3 disc injury on stability of C1-C2 ...
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 a...
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 ...

Atlantoaxial fusionAtypical C2 fractures summarise all fracture types of the axis corpus that are not subsumed under odontoid fractures or traumatic spondylolisthesis of C2 (Hangman fractures). They are most often classified according to Benzel [1] in predominantly coronar (type 1), sagittal (type 2...
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 ...
