## TL;DR

A clinical case of an elderly patient with a type-II odontoid fracture treated using a combined anterior fixation technique is presented, showing benefits over traditional posterior approaches.

## Contribution

A combined anterior fixation technique using transarticular and odontoid screws is proposed for treating type-II odontoid fractures in elderly patients.

## Key findings

- The anterior fixation technique provides sufficient stability for type-II odontoid apophysis fractures.
- The technique results in less cervical extensor musculature dissection and reduced hemorrhage compared to posterior approaches.
- The method is feasible and beneficial for geriatric patients with comorbidities.

## Abstract

Fractures of the odontoid apophysis are one of the most frequent lesions in the elderly population, and an increasingly preponderant problem with the progressive aging of the world population.

In the present work, we report a clinical case of an 88-year-old male patient who suffered a fall resulting in a type-II fracture of the odontoid apophysis on the Anderson-D'Alonzo classification. Given the age and comorbidities of the patient, we decided to perform osteosynthesis of the fracture through anterior fixation with a transarticular screw in combination with fixation with an odontoid screw.

This technique enables the necessary stability for the consolidation of Anderson-D'Alonzo's type II odontoid apophysis fracture, with the advantage of the lower levels of dissection of the cervical extensor musculature and hemorrhage resulting from this aggression when compared with the posterior approach; moreover, it is a readily-available technique that yields clear benefits in the treatment of this pathology in the geriatric population.

As fraturas da apófise odontoide são uma das lesões mais frequentes na população idosa, e um problema cada vez mais preponderante com o envelhecimento progressivo da população mundial.

Neste trabalho, apresentamos um caso clínico de um doente do gênero masculino, de 88 anos, que sofreu uma queda da qual decorreu uma fratura da apófise odontoide de tipo II de Anderson-D'Alonzo. Dada a idade e suas comorbilidades, optou-se por realizar a osteossíntese da fratura por meio da fixação anterior com parafuso transarticular em combinação com a fixação com parafuso à odontoide.

Esta técnica que permite a estabilidade necessária para a consolidação da fratura da apófise odontoide de tipo II de Anderson-D'Alonzo, com a vantagem das menores disseção da musculatura extensora cervical e hemorragia decorrente desta agressão quando comparada com a abordagem posterior, sendo uma técnica à disposição e que acarreta benefícios claros no tratamento desta patologia na população geriátrica.
