Distal Forearm Fractures

BackgroundPaediatric distal forearm fractures are a common ED presentation. They can be diagnosed with point-of-care ultrasound (POCUS) as an alternative to X-rays. Given that ED nurse practitioners (NPs) are relied on for the diagnosis of paediatric fractures, it is important to describe the diagnostic accuracy of NP-conducted POCUS versus X-ray.MethodsThis prospective diagnostic study was conducted in a tertiary paediatric hospital in Queensland, Australia, between February 2018 and April 2019. Participants were children aged 4–16 years with a clinically non-angulated, suspected distal forearm fracture. Diagnosis from 6-view NP-administered POCUS of the distal radius and ulna was compared against the reference standard of 2-view X-ray. Each patient received both imaging modalities. Overall forearm diagnosis was classified as ‘no’, ‘buckle’ or ‘other’ fracture for both modalities. The primary outcome was diagnostic accuracy for ‘any’ fracture (‘buckle’ and ‘other’ fractures combined). Secondary outcomes included diagnostic accuracy for ‘other’ fractures versus ‘buckle’ and ‘no’ fractures combined, and pain, imaging duration and preference for modality.ResultsOf 204 recruited patients, 129 had X-ray-diagnosed forearm fractures. The sensitivity and specificity for NP-administered POCUS were 94.6% (95% CI 89.2% to 97.3%) and 85.3% (95% CI 75.6% to 91.6%), respectively. ‘Other’ fractures (mostly cortical breach fractures), when compared with ‘buckle’/ ‘no’ fractures, had sensitivity 81.0% (95% CI 69.1% to 89.1%) and specificity 95.9% (95% CI 91.3% to 98.1%). Pain and imaging duration were clinically similar between modalities. There was a preference for POCUS by patients, parents and NPs.ConclusionsNP-administered POCUS had clinically acceptable diagnostic accuracy for paediatric patients presenting with non-angulated distal forearm injuries. This included good sensitivity for diagnosis of ‘any’ fracture and good specificity for diagnosis of cortical breach fractures alone. Given the preference for POCUS, and the lack of difference in pain and duration between modalities, future research should consider functional outcomes comparing POCUS with X-ray in this population in a randomised controlled trial.

Distal Forearm Fractures

BackgroundDistal forearm fractures are common in children. The reference standard to diagnose these fractures is by conventional radiography, which exposes these patients to harmful radiation. Ultrasound (US) seems to be a good alternative. However, emergency physicians (EPs) in the Netherlands have limited experience in using US for diagnosing fractures in children.ObjectiveThe primary objective was to determine the accuracy of US, performed by a Dutch EP, compared with conventional radiography, in diagnosing distal forearm fractures in children. As a secondary objective, differences in pain scores during the performance of both US and plain radiography were determined.MethodsChildren, aged between 0 and 14 years old, suspected of having a distal forearm fracture were enrolled at the Emergency Department. US and radiographic findings were compared. Statistics for accuracy were calculated. Pain scores were recorded during US and radiography and compared as well. All participating operators received an hour-long pretrial training.Results100 patients were enrolled. The mean age was 9.5 years (SD, 3.6), and 50% were women. Overall diagnostic accuracy was 92% (95% CI 85%-96%). The sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios for US were 95% (95% CI 87% to 99%), 86% (95% CI 71% to 95%), 92% (95% CI 83% to 97%), 91% (95% CI 76% to 98%), 6.86 (95% CI 3.04 to 15.51) and 0.05 (95% CI 0.02 to 0.17), respectively. The pain scores during US and radiographic imaging were 3.3 and 4.6, respectively (p<0.01).ConclusionsIn this study, we showed that US is an accurate method for diagnosing distal forearm fractures in children. The main advantages are that it is radiation-free and rapidly practicable, and that patients experience it as less painful than radiography. Moreover, this study has proven that with minimal experience in US, good diagnostic accuracy can be achieved after brief training.

BackgroundFollowing blunt trauma, diagnosis of shoulder dislocation based on physical examination alone is difficult due to possible concurrent proximal humeral fractures. X-rays are therefore used to confirm diagnosis. Results from recent observational studies comparing diagnostic accuracy of point-of-care ultrasound (PoCUS) with X-rays for shoulder dislocation have been encouraging. The aim of this study was to determine whether PoCUS improves diagnostic accuracy when used with physical examination for the diagnosis of shoulder dislocation, proximal humeral fracture and ascertaining successful reduction in the ED.MethodsA prospective, single-centre, open, parallel randomised control study over a 6-month period was used to answer the research question and test the null hypothesis. Consecutive eligible adult patients attending the ED of Mater Dei Hospital in Malta were randomised to either the control (C) (physical examination only) or experimental group (E) (physical examination and a two-point PoCUS scan). The study objectives were to measure diagnostic accuracy for both examinations for detecting shoulder dislocation, any associated proximal humeral fractures and confirming reduction. X-rays were used as reference standard for both groups.Results1206 patients were enrolled in this study (C n=600, E n=606). 290 dislocations (C n=132 and E n=158), 332 proximal humeral fractures (C n=154 and E n=178) and 278 reductions (C n=130 and E n=148) were analysed. A statistically significant difference (p<0.001) was found between the two groups for diagnostic accuracy in shoulder dislocation (C=65%, likelihood ratio (LR)+=2.03 and LR−=0.35 and E=100%, LR+=∞ and LR−=0), proximal humeral fractures (C=45.7%, LR+=1.23 and LR−=0.52 and E=98.3%, LR+=103.9 and LR−=0.03) and reduction (C=68.7%, E=100%). The null hypothesis for this study was thus rejected.ConclusionsThe addition of PoCUS to a physical examination significantly improves diagnostic accuracy for dislocations, proximal humeral fractures and reduction confirmation.Trial registration numberInternational Standard Randomised Controlled Trials Number Registry (ISRCTN17048126).

Abstract Background Distal forearm fractures are the most common fractures in childhood and can be diagnosed with ultrasound. The aim of this study was to demonstrate the eligibility of Wrist SAFE for clinical use and the avoidance of X-ray application in children. Methods We enrolled patients from 0 – 12 years with suspected distal forearm fractures. They were treated according to the Wrist SAFE algorithm, a detailed pathway for ultrasound fracture diagnosis, treatment decisions and control options. Additionally, 9 clinical predictors were tested. Depending on sonographic and clinical findings, patients were treated with functional movement, immobilization or surgery. Follow-up was conducted after 5 days and 3 months. Results 16 physicians (6 specialists, 10 assistants) at 5 study sites examined 498 (234 boys, 251 girls, 13 not specified) patients with ultrasound, age 8.4 (0 – 12) years. 321 (64 %) patients were diagnosed with a fracture, 5 (0.8 %) with suspected fracture; X-rays were conducted in 58 cases (12 %), 9 (1.8 %) of them on day 1 and 49 (9.8 %) on day 5; sonographic diagnosis was confirmed in 57 of 58 (98 %) cases; in one case, the sonographic diagnosis of “contusion” was revised to “radius fracture”. 381 patients (77 %) underwent final follow-up after an average of 96 (62 – 180) days. All patients were symptom-free at that time. Palpatory bone pain over the radius/ulna and swelling were identified as clinical predictors. 81 % of X-rays were avoided. Conclusion Wrist SAFE enables the safe diagnosis and therapy of distal forearm fractures in children. Findings can be reviewed safely, also enabling physicians in training to use the method. 81 % of X-rays can be avoided, a figure that corresponds to 2.8 million X-rays in the G10 member states. After performing 100 examinations, physician have acquired the necessary sonography skills.
