Mid-Term Outcomes Of Fracture Odontoid Management in Assiut University
Mid-Term Outcomes Of Fracture Odontoid Management in Assiut University
The aim of this study is to evaluate and assess the mid-term outcomes of treating odontoid fracture cases admitted to the Trauma Unit of Assiut University Hospital.
Odontoid fractures are common fractures of the cervical spine, accounting for 10-15% of all cervical spine fractures. It has a bimodal age distribution as it occurs in both elderly and young patients. The injury generally occurs as a result of strong flexion and extension movement in addition to axial overload. Flexion generally results in anterior subluxation, while extension results in posterior subluxation.
It was classified by Anderson and D'Alonzo Classification in 1974 into three types according to the fracture location. A newer classification was introduced which offered a clearer distinction between type-II and type-III fractures. In this new classification, Type II fractures were further divided into 3 subtypes. The 3 subtypes are labelled A, B, and C. Type II fractures are usually treated surgically through either anterior or posterior approach depending on the fracture pattern as they are characterized by a higher rate of non-union compared to type I and III being in a watershed level between the vertebral and the internal carotid arteries. Nevertheless, the literature is still confusing about the results of anterior surgery in odontoid fractures.
In a recent study by Cutler et al., anterior fixation of odontoid fracture was associated with high morbidity and mortality. In another study, the most commonly reported major complications after odontoid fracture surgery in the elderly include cardiac failure, deep venous thrombosis , stroke, pneumonia, respiratory failure, liver failure, and severe infection.
Despite the fact that we receive and treat a large number of patients with various types of odontoid fractures in Assiut University Hospital, there is no consensus about the best treatment options and uncertainty about the mid and long term outcome of these treatments.
In this study, the investigators will assess the mid-term outcomes (minimum of one year) to all patients with odontoid fracture who are admitted to the Trauma Unit in Assiut University Hospital regardless the treatment type.
