The diaphragm is the main muscle of respiration. If the phrenic nerve is damaged, it is possible that the patient suffers from ventilatory disorders. If you have a sliding of vertebrae or bone debris, this fracture can cause a spinal cord compression. They can cause functional disorders such as balance disorders. This can radiate to the shoulder or arm ( cervico-brachial neuralgia). Le main symptom of fracture of the odontoid is a severe localized neck pain ( acute neck pain). What are the symptoms of an axis fracture? The spinal canal may be constricted and bone fragments may injure the spinal cord in the worst case. On the other hand, if the fracture is unstable, discs, ligaments and joints are damaged. Sourceĭuring a stable fracture, soft tissues and ligaments are not affected and the Spinal canal remain intact. Type III: it is a stable fracture with a line crossing the vertebral body of the C2 or the base of the odontoid.In the elderly, this type of fracture exposes you to the risk of pseudarthrosis. Type II: it is an unstable fracture whose fracture line is located at the level of the neck of the odontoid.The fracture line is located at the level of the tip of the odontoid and gives a tearing appearance. suicide attempts by hanging (hangman's fracture).ĪCCESS THE LOMBAFIT CONSULTATION Classification of odontoid fracturesĪccording to Anderson and Alonzo classification, we can distinguish 3 types of odontoid fractures.work or traffic accidents ( whiplash ou cervical sprain).une osteoporosis (progressive loss of bone density weakening the bones).In addition to falls and polytrauma, odontoid fractures can also be linked to other pathologies such as: On the other hand, in young subjects, they can follow multiple traumas. In subjects over the age of 70, they constitute fractures of the cervical spine the most common in the event of a fall. Park guide walks odontoid fractures account for about 60% of fractures of the axis with a frequency that oscillates between 7 and 14%. This is what makes possible the rotation of the atlas and the head (90° left and right). The odontoid process plays a pivotal role. The particularity of the morphology of the axis gives it a very important function in the mobility of the neck. the apical ligament which allows it to be attached to the occipital bone of the head.the transverse ligament which allows it to articulate with the atlas.Top 10 Best Pillow for Chiari Malformation (Tested by Experts!) What are the complications of cervical fracture?.Surgical treatment of an odontoid fracture.Orthopedic treatment of a fracture of the axis.A scanner to assess the fracture of the odontoid.How to make the diagnosis of odontoid fracture?.What are the symptoms of an axis fracture?.In the current study, 21% of patients were unsuccessfully treated nonoperatively with external immobilization and required surgery. No statistical advantage of halo vest versus hard collar orthosis was observed.Ĭomplex Type III odontoid fractures are distinctly different from low-energy injuries. Initial fracture displacement and angulation were not correlative with final outcome. Two additional patients required delayed surgery for nonunion and myelopathy. Seven patients demonstrated progressive displacement of either 2 mm of translation or 5° of angulation and underwent delayed surgical stabilization. Thirty-three patients met the inclusion and exclusion criteria including 15 patients treated in a halo vest and 18 in a hard collar orthosis. One hundred and twenty-five Type III odontoid fractures were identified with 51% classified as complex fractures. Patients were treated in either a hard collar orthosis or halo vest and were followed for fracture union and stability. Fractures were categorized as high- or low-energy fracture with high-energy fractures defined as those with lateral mass comminution (>50%) or secondary fracture lines into the pars interarticularis or vertebral body. Acute Type III odontoid fractures were identified at a single institution from 2008 to 2015.
