External validation of the clinical indications of computed tomography (CT) of the head in patients with low-energy geriatric hip fractures.

INTRODUCTION: On evaluation of the clinical indications of computed tomography (CT) scan of head in the patients with low-energy geriatric hip fractures, Maniar et al. identified physical evidence of head injury, new onset confusion, and Glasgow Coma Scale (GCS)<15 as predictive risk factors for acute findings on CT scan. The goal of the present study was to validate these three criteria as predictive risk factors for a larger population in a wider geographical distribution. PATIENTS AND METHODS: Patients ≥65 years of age with low-energy hip fractures from 6 trauma centers in a wide geographical distribution in the United States were included in this study. In addition to the relevant patient demographic findings, the above mentioned three criteria and acute findings on head CT scan were gathered as categorical variables. RESULTS: In total 799 patients from 6 centers were included in the study. There were 67 patients (8.3%) with positive acute findings on head CT scan. All of these patients (100%) had at least one criteria positive. There were 732 patients who had negative acute findings on head CT scan with 376 patients (51%) having at least one criteria positive and 356 patients (49%) having no criteria positive. Sensitivity of 100% and negative predictive value of 100% was observed to predict negative acute findings on head CT scan when all the three criteria were negative. CONCLUSION: With the observed 100% sensitivity and 100% negative predictive value, physical evidence of acute head injury, acute retrograde amnesia, and GCS<15 can be recommended as a clinical decision guide for the selective use of head CT scans in geriatric patients with low energy hip fractures. All the patients with positive acute head CT findings can be predicted in the presence of at least one positive criterion. In addition, if these criteria are used as a pre-requisite to order the head CT, around 50% of the unnecessary head CT scans can be avoided.

Fragility fracture programs: are they effective and what is the surgeon's role?

Fragility fractures are occurring at an ever-increasing rate, creating an enormous economic and societal impact. Outpatient-based fragility fracture programs have been developed to identify at-risk patients, initiate effective treatment of metabolic bone disease, and improve coordination between members of the patient's care team with the goal of reducing future fractures. Inpatient programs focus on effective, efficient management of patients presenting with acute fractures. Both have proven successful in reducing the impact of fragility fractures, but many challenges exist. The orthopedic surgeon, as part of an integrated team of providers, is integral in identifying at-risk patients, ensuring appropriate care of acute fractures, and initiating treatment protocols to reduce the risk of further injuries.
