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 a C2 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.

Nail Fit: Does Nail Diameter to Canal Ratio Predict the Need for Exchange Nailing in the Setting of Aseptic, Hypertrophic Femoral Nonunions?

OBJECTIVES: To evaluate patient-independent risk factors for aseptic femoral hypertrophic nonunion requiring exchange nailing, with particular reference to the fit of the nail at the isthmus within the canal. DESIGN: Retrospective case control study. SETTING: Level 1 trauma center. MAIN OUTCOME MEASUREMENTS: Between 2008 and 2012, 211 patients without any patient-dependent risk factors for nonunion were treated with a locked reamed intramedullary nail for a femoral shaft fracture. Twenty-three cases went on to hypertrophic nonunion requiring exchange nailing (treatment group) and 188 cases went on to union (control group). Patient-independent risk factors for exchange nailing were documented. RESULTS: Patient-independent risk factors for exchange nailing were poor fracture reduction [Odds ratio (OR): 11.5, 95% confidence interval (CI), 4.0-33.4, P < 0.001], open fracture (OR: 7.6, 95% CI, 3.0-19.6, P = 0.004), Winquist classification of 4 (OR: 4.4, 95% CI, 1.9-6.7, P = 0.016), and poor nail fit (OR: 10.3, 95% CI, 5.1-28.4, P < 0.001). Multivariate analysis revealed nail fit as an independent predictor of femoral nonunion requiring exchange nailing (OR: 11.4, 95% CI, 6.9-15.2, P < 0.001). Moreover, we found a direct relationship between increasingly poor nail fit and increased risk of exchange nailing, with the criterion occurring at a nail fit ratio <70%. CONCLUSION: When proceeding to femoral fracture reamed intramedullary nailing, we recommend a minimum nail fit of 70% at the isthmus and ideally 90% or more, to avoid surgical reintervention. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Magnetic resonance imaging findings in pediatric bilateral vocal fold dysfunction.

OBJECTIVES: We studied the findings of brain magnetic resonance imaging (MRI) in infants with idiopathic congenital bilateral vocal fold dysfunction (CBVFD). METHODS: We performed a retrospective investigation of a case series. RESULTS: We identified 26 children (14 male, 12 female) over 11 years. Three children were excluded. Thirteen patients required airway interventions, including continuous positive airway pressure (4 patients), endotracheal intubation (1), and tracheostomy (8). The findings on brain MRI were abnormal in 8 patients (35%). Tracheostomy was required in 3 patients (38%) with abnormal MRI findings, as compared with 5 of 15 patients (33%) with normal MRI findings. The MRI abnormalities involved evidence of white matter injury (2), abnormal white matter signal (1), subdural blood (3), cerebral swelling (1), and perisylvian polymicrogyria (1). The cranial ultrasound findings were abnormal in 4 of 11 patients. The MRI findings were abnormal in 2 of 7 children in whom the cranial ultrasound findings were normal, and in 2 of the 4 patients in whom the cranial ultrasound findings were abnormal. CONCLUSIONS: The MRI abnormalities were nonspecific; however, they may indicate unrecognized perinatal intracranial injury as being related to CBVFD. In addition, MRI may reveal an underlying structural brain anomaly. Cranial ultrasound has poor sensitivity and specificity. Hence, MRI should be considered as part of the routine assessment of neonates with CBVFD.
