Outcomes after application of halothoracic orthosis for cervical spine trauma

Background: Cervical spine fractures can be managed operatively or nonoperatively, considering injury type and patient factors. Nonoperative management may include application of a halothoracic orthosis (HTO). The aim of our study was to describe our patients managed with HTO, review their 6-month and 12-month outcomes, and identify associated factors. Methods: Patients fitted with an HTO at our institution in 2014 were included. Data collected included patient demographics, hospital-related data, and radiological union. Injury detail and 6-month and 12-month patient-reported outcomes (Glasgow Outcomes Scale Extended and return to work [RTW]) were accessed through Victorian Orthopedic Trauma Outcomes Registry. Factors related to these outcomes were included in a mixed-effect regression model for each outcome. Results: Eighty-six patients (median age 46.5 years) of whom 52 (60%) were male individuals were included. Two-thirds (57 patients) were road trauma patients, and 58 patients (67%) experienced an isolated injury. Thirty-seven patients (43%) experienced aC2 fracture and 27 (31%) experienced a facet fracture. Twelve-month follow-up was completed for 78 patients (91%) with 27 (35%) reporting a good recovery, and 65% (31/48) patients returned to work. Factors associated with lower odds of RTW included compensation, a facet joint fracture, and experiencing comorbidities. No factors were significantly associated with functional outcome, although female individuals exhibited a slower recovery trajectory than male individuals. Conclusion: Many patients reported poor 12-month outcomes after HTO for traumatic injury. Factors associated with worse outcomes should be considered when deciding on management of patients with cervical spine fractures.
