A hangman's fracture is the colloquial name given to a fracture of both pedicles or pars interarticularis of the axis vertebra (C2) (or epistropheus).
ICD10 DIAGNOSIS FOR ODONTOID FRACTURE TYPE 2 CODE
If this is a fixed defect, C2 is rotated in conjunction with C1. The ICD code S121 is used to code Hangman's fracture. The head may be pointed anteriorly, C1 is turned. On CT, C1 is not oriented in line with the head. In a vertical subluxation, the dens is often above the McGregor line by over 8 mm in men and 9.7 mm in women. The expected distance between the anterior arch of C1 and the dens in the fully flexed position should be <3 mm in an adult (~5 mm in a child) 5. Although fractures of the odontoid occur in all age groups, younger patients often sustain these injuries after motor vehicle accidents while older patients present after low-energy falls and are less likely to have severe neurological deficits 10, 32, 60, 63, 68.
Pathology The mechanism of injury is variable, and can occur both during flexion or extension, and with or without compression 5. of surgical versus conservative treatment of isolated type II odontoid fractures in. In a non-traumatic setting, flexion and extension views may be performed. Odontoid process fracture, also known as a peg or dens fracture, occurs where there is a fracture through the odontoid process of C2. Patients undergoing CF were defined through ICD-10 procedure codes.
Atlanto-axial subluxations are often associated with high energy traumas, with higher occurrence among children and young adults 6. Odontoid Fractures are relatively common fractures of the C2 (axis) dens that can be seen in low energy falls in elderly patients and high energy traumatic injuries in younger patients.
