Arch Orthop Trauma Surg 2024; 144:3025-3043. [PMID: 38953942 DOI: 10.1007/s00402-024-05396-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Accepted: 05/29/2024] [Indexed: 07/04/2024]
Abstract
Over a span of more than two years, a collaborative expert group consisting of 9 professional societies has meticulously crafted the S2e guideline on fracture sonography. This publication encapsulates the essential insights pertaining to specific indications. A thorough and systematic literature search, covering the period from 2000 to March 2021, was conducted across PubMed, Google Scholar, and the Cochrane Database of Systematic Reviews, complemented by an evaluation of bibliographies. Inclusion criteria encompassed randomized controlled clinical trials, observational clinical trials, meta-analyses, and systematic reviews, while guidelines, conferences, reviews, case reports, and expert opinions were excluded. The SIGN grading system (1999-2012) was applied to assess evidence, and resultant SIGN tables were presented to the expert group. Specific recommendations for the application of fracture sonography were then derived through unanimous consensus after detailed discussions. Out of the initial pool of 520 literature sources, a meticulous screening and content assessment process yielded 182 sources (146 clinical studies and 36 meta-analyses and systematic reviews) for evaluation. The comprehensive analysis identified twenty-one indications that substantiate the judicious use of fracture sonography. Ultrasound emerges as a pragmatic and user-friendly diagnostic method, showcasing feasibility across a diverse range of indications.

Abstract
PURPOSE Over the course of more than two years, an expert group of 9 professional societies has created the S2e guidelines for fracture sonography. This publication summarizes the key points regarding the individual indications. MATERIALS AND METHODS A systematic literature search was performed in PubMed, Google Scholar, and the Cochrane Database of Systematic Reviews from 2000 to March 2021 with evaluation of the literature lists. Randomized controlled clinical trials, observational clinical trials, meta-analyses, and systematic reviews were included. Guidelines, conferences, reviews, case reports, and expert opinions were excluded. Evidence was graded using the SIGN grading system 1999-2012, and the SIGN tables were then presented to the expert group. These were used to develop specific recommendations for the use of fracture sonography. All recommendations were discussed in detail and finally unanimously agreed upon. RESULTS Of the 520 primary literature sources found, 182 sources (146 clinical studies and 36 meta-analyses and systematic reviews) were evaluated after screening and content assessment. 21 indications that allow reasonable application of fracture sonography were identified. CONCLUSION Ultrasound is a sensible, easy-to-use diagnostic method that is feasible for a large number of indications.

Abstract
BACKGROUND Sonography is a beneficial imaging modality for detecting elbow fractures in children, considering the lack of radiation exposure and time efficiency. This systematic review aims to determine the diagnostic value and clinical applicability of sonography and each sonographic finding in detecting pediatric elbow fractures. METHODS Pubmed, Scopus, and WOS databases were searched for related original articles until February 25, 2023, and data related to diagnostic performance were extracted. We used the Bivariate model and hierarchic summary receiver operating characteristic (HSROC) approach to calculate pooled diagnostic values. Cochrane Q test and I-squared were performed to evaluate heterogeneity. We assessed heterogeneity with meta-regression. RESULTS Eight studies were included, which involved a total number of 880 patients. According to meta-analysis, sonography demonstrated a pooled sensitivity of 97% (91-99%) and specificity of 90% (80-95%), positive likelihood ratio(LR+) of 9.82 (4.59-20.97), and negative likelihood ratio (LR-) of 0.03 (0.01-0.10). For the sonographic posterior fat pad sign as a sole diagnostic sign, we calculated a Pooled Sensitivity of 80% (70-88%), Specificity of 97% (87-99%), LR+ of 28.8 (6-139.3), and LR- of 0.2 (0.13-0.31). Also, lipohemarthrosis demonstrated a pooled sensitivity of 80% (70-88%), specificity of 97% (87-99%), LR+ of 28.8 (6-139.3), and LR- of 0.2 (0.13-0.31). The sensitivity of detecting fractures with cortical line disruption was significantly higher in studies that utilized a comprehensive technique compared to a conventional technique. CONCLUSIONS Sonography is a valuable diagnostic tool for the assessment of pediatric elbow injuries, and it can be capable of confirmation or exclusion of the diagnosis.

[PMID: 37673759 DOI: 10.1016/j.injury.2023.111005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 08/07/2023] [Accepted: 08/20/2023] [Indexed: 09/08/2023]
Abstract
BACKGROUND Two-way direct radiography is the first-choice imaging method for pediatric patients presenting to the emergency department with elbow trauma. Although, unlike radiography, ultrasonography (US) is not used routinely, studies show that US can be used in the diagnosis of fractures in pediatric patients. METHODS In this single-center prospective observational study, patients under the age of 18 who presented to the emergency department after sustaining elbow trauma constituted the population of the study. Findings of the posterior fat pad sign using bedside US and the result obtained by seven-point assessment of the bone cortex were compared with the final diagnosis. RESULTS Of the 128 patients enrolled in the study, 6 patients were excluded due to various reasons. Seventy (57.4%) patients were male, and median age was 7.7 years. On examining the final diagnosis of the patients at the emergency department, fracture diagnosis was observed in 39 patients (32%). It was determined that fracture diagnosis for 94.9% of the patients included in the study could be achieved using US (in the presence of at least the fat pad sign and/or direct findings of fracture based on the seven-point assessment). CONCLUSION US should be considered as a diagnostic tool in cases of pediatric elbow traumas owing to its high sensitivity and negative predictive value. US, which is reproducible, ionizing radiation-free, and can be performed at the bedside, can considerably reduce unnecessary radiography in low-risk patients when evaluated along with physical examination findings among patients in the pediatric age group presenting with elbow trauma. We believe that the result of our study will contribute to patient care practices.

Abstract
Supracondylar fractures are common injuries in children. Diagnosis typically relies on radiography, which can involve long wait times in the ED, emits ionizing radiation, and can miss non-displaced fractures. Ultrasound (US) has the potential to be a safer, more convenient diagnostic tool, especially with new highly portable handheld 2D point of care US (POCUS). This study aimed to determine the reliability of 2D POCUS for the detection of supracondylar fractures and elbow joint effusions, to contrast the accuracy of 2D POCUS vs. 3DUS vs. radiographs, and to determine whether blinded image interpretation could produce similar results to non-blinded real-time imaging. Fifty-seven children were scanned with 2D POCUS and 3DUS on the affected elbow. US scans were then read by three blinded readers, and the results were compared to gold-standard radiographs. Compared to a gold standard of 30-day radiographic diagnosis, readers of 2D POCUS detected supracondylar fracture and effusion with sensitivities of 0.91 and 0.97, respectively, which were both higher than with 3DUS. Inter-rater reliability of fracture detection was moderate for 2D POCUS (k = 0.40) and 3DUS (k = 0.53). Consensus sensitivities, although high, were lower than reports from some non-blinded studies, indicating that clinical presentation serves as an important factor in detection rates. Our results from consensus US diagnosis support the validity of using 2D POCUS in children for supracondylar fracture and elbow effusion diagnosis.

Abstract
Objective We evaluated the impact of Point-of-care ultrasound (POCUS) in musculoskeletal consultations out of hospital using a Philips Lumify portable ultrasound device. We aimed to determine the impact of POCUS on the number of hospital referrals for injections as well as on the number of injections performed in consultation. Design Retrospective case study comparing 2 periods: June to September 2021 (pre-POCUS) and November 2021 to February 2022 (POCUS). Statistical comparisons were performed using the χ2. In both periods, 21 medical consultations were performed. In the pre-POCUS period, 470 patients were assessed, with an average of 1.29 hospital referrals made per day of consultation for hospital injections and an average of 2.05 injections performed per day of medical consultation. In the POCUS period, 589 patients were assessed, with an average of 0.1 hospital referrals per day (-92.6%; p < 0.00001) and an average of 2.76 injections performed per day (+34.9%; p < 0.00001). The introduction of POCUS at our practice reduced the number of hospital referrals made for injections and increased the number of injections performed every day of consultation. Conclusion This suggests that POCUS is of great clinical value in out-of-hospital musculoskeletal rehabilitation consultations.

Abstract
Point of Care Ultrasound (POCUS) is used to evaluate the injured pediatric elbow. Standard of care, however, remains radiography. POCUS performed in the setting of normal radiographs have been obtained may demonstrate radiologic occult lipohemarthrosis indicative of occult fracture. We reviewed our pediatric emergency department (PED) POCUS archive for lipohemarthrosis, and then isolated those cases with normal elbow radiography. Radiography was deemed to be normal per the interpretation of the treating PED physician, and was reviewed for this series by an experienced ABR board certified pediatric radiologist. Fracture on POCUS was defined as fracture line or lipohemarthrosis in a posterior sagittal or transverse view of the distal humerus. Fracture was confirmed by signs of cortical healing on follow-up radiography, or clinical course consistent with fracture as documented by an orthopedist. We identified four children with elbow fractures who had no fracture line or elevated posterior fat pad on radiography but demonstrated lipohemarthrosis on POCUS. POCUS may elicit evidence of fracture even after normal radiography, and POCUS findings suggesting occult fracture may allow for more effective guidance on discharge.

Diagnostic Accuracy of 3D Ultrasound and Artificial Intelligence for Detection of Pediatric Wrist Injuries. CHILDREN-BASEL 2021; 8:children8060431.

Abstract
Wrist trauma is common in children, typically requiring radiography for diagnosis and treatment planning. However, many children do not have fractures and are unnecessarily exposed to radiation. Ultrasound performed at bedside could detect fractures prior to radiography. Modern tools including three-dimensional ultrasound (3DUS) and artificial intelligence (AI) have not yet been applied to this task. Our purpose was to assess (1) feasibility, reliability, and accuracy of 3DUS for detection of pediatric wrist fractures, and (2) accuracy of automated fracture detection via AI from 3DUS sweeps. Children presenting to an emergency department with unilateral upper extremity injury to the wrist region were scanned on both the affected and unaffected limb. Radiographs of the symptomatic limb were obtained for comparison. Ultrasound scans were read by three individuals to determine reliability. An AI network was trained and compared against the human readers. Thirty participants were enrolled, resulting in scans from fifty-five wrists. Readers had a combined sensitivity of 1.00 and specificity of 0.90 for fractures. AI interpretation was indistinguishable from human interpretation, with all fractures detected in the test set of 36 images (sensitivity = 1.0). The high sensitivity of 3D ultrasound and automated AI ultrasound interpretation suggests that ultrasound could potentially rule out fractures in the emergency department.

Abstract
BACKGROUND Elbow injuries and fractures are a common pathology in the pediatric emergency unit. X-ray and CT scan of the elbow are the standard diagnostic procedures, which increase exposure to radiation in children. Previous studies have shown that fractures can also be visualized by ultrasound (US); thus, this study aimed to evaluate the diagnostic accuracy of elbow US compared with radiography for the diagnosis of elbow fracture in children. MATERIALS AND METHODS This was a prospective observational study of patients aged 2-14 years that presented to emergency departments with a suspected elbow fracture requiring radiographic evaluation. Elbow US for diagnosing elevated posterior fat pad or lipohemarthrosis was performed. All patients underwent elbow radiography and received clinical follow-up. Initial or follow-up X-ray or CT scan was used as the reference standard for fracture diagnosis. RESULTS Seventy-five patients with a mean age of 6.51 ± 3.68 years were enrolled in the study. Twenty-eight (37.3%) patients had positive results for fracture. The sensitivity, specificity, and accuracy of US in the diagnosis of elbow fractures were 92.9% (95% CI 76.5-99.1%), 89.4% (95% CI 76.9-96.5%) and 90.7% (95% CI 81.7-96.2%). In patients with fracture, US demonstrated a lipohaemarthrosis in 20 patients (71.4%), elevated posterior fat pad in 19 patients (67.9%), cortical disruption in 10 patients (35.7%), and effusion in three patients (10.7%). CONCLUSION Our results showed high diagnostic accuracy for the ultrasonography diagnosis of an elbow fracture, which allows us to confirm ultrasonography imaging of the elbow as a safe alternative in the primary evaluation of pediatric elbow injuries.

J Orthop Surg Res 2021; 16:32. [PMID: 33422107 PMCID: PMC7797123 DOI: 10.1186/s13018-020-02174-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Accepted: 12/25/2020] [Indexed: 11/26/2022] Open
Abstract
Background Evaluating of the articular cartilage status of the distal humeral epiphysis is difficult. Ultrasound imaging of the elbow is increasingly being used to confirm the integrity of the articular cartilage of minimally displaced lateral humeral condyle fractures in children with minimally displaced fractures. The aims of this study were to assess the correlations between ultrasound and arthrography findings for predicting the integrity of the cartilage hinge and to describe the utility of ultrasound in determining the need for pre-treatment. Methods Thirty-nine patients with minimally displaced lateral humeral condyle fractures who underwent ultrasound and arthrography examinations before surgery from May 2018 to December 2019 were included in this study. Ultrasound and arthrography predictors of the cartilage hinge status were independently measured. The ultrasound and arthrography results were compared. Results The mean displacement of the fractures was 3.1 mm (range, 2.0~5.0 mm). Arthrography showed incomplete fractures in 24 patients (61.5%) and complete fractures in 15 patients (38.5%). Ultrasound showed incomplete fractures in 25 patients (64.1%) and complete fractures in 14 patients (35.9%). The ultrasound and arthrography results of the integrity of the articular surface were consistent in 92.3% of the cases, including 23 that were predicted to have an intact articular surface and 13 that were predicted to have an incongruity articular surface. There was no correlation between the displacement and the fracture appearing complete on the ultrasound scan. The Pearson coefficient between ultrasound and arthrography for assessing the integrity of the articular surface was 0.837. Conclusions Ultrasound and arthrography assessments of the integrity of the cartilage hinge status appear to be highly consistent. Ultrasound can be used as a complementary tool with arthrography to predict the integrity of the cartilage hinge status in children with minimally displaced lateral humeral condyle fractures. Level of evidence Prospective study; level II.

Abstract
OBJECTIVE Ultrasound has an excellent diagnostic accuracy for fractures that is reportedly comparable to plain radiographs. We aim to summarize the diagnostic accuracy of ultrasound for upper extremity fractures in children. METHODS Databases were searched from inception through November 2019 using pre-defined index terms, including "ultrasound," "fractures of upper extremities" and "children". The study is reported using Preferred Reporting Items for a Systematic Review and Meta-analysis of Diagnostic Test Accuracy Studies (PRISMA-DTA). Meta-analysis of the diagnostic accuracy of ultrasound for fractures was conducted using the random-effects bivariate model. Subgroup analysis of fracture site (elbow vs non-elbow fractures) was also performed. Meta-regression was performed to determine if the site of fracture affected the diagnostic accuracy. RESULTS Thirty-two studies were identified in the meta-analysis. Ultrasound for fractures of the upper extremities has a sensitivity: 0.95 (95% CI: 0.93-0.97), specificity: 0.95 (95% CI: 0.91-0.98), positive likelihood ratio: 21.1 (95% CI: 10.8-41.5) and negative likelihood ratio: 0.05 (95% CI: 0.03-0.07), with an area under ROC (AUROC) curve of 0.98 (95% CI: 0.97-0.99). Subgroup analysis for elbow fracture showed ultrasound has a sensitivity: 0.95 (95% CI: 0.86-0.98), specificity: 0.87 (95% CI: 0.76-0.94), positive likelihood ratio: 7.3 (95% CI: 3.7-14.4) and negative likelihood ratio: 0.06 (95% CI: 0.02-0.16), with an AUROC of 0.96 (95% CI: 0.94-0.97). Meta-regression suggested the fracture sites would affect diagnostic accuracy of ultrasound (elbow vs non-elbow, p < 0.01). CONCLUSIONS Current evidence suggests ultrasound has excellent diagnostic accuracy for non-elbow upper extremity fractures in children, serving as an alternative diagnostic modality to plain radiographs.

Clinical Guidance for Point-of-Care Ultrasound in the Emergency and Critical Care Areas after Implementing Insurance Coverage in Korea. J Korean Med Sci 2020; 35:e54.

Abstract
Point-of-care ultrasound (POCUS) is a useful tool that is widely used in the emergency and intensive care areas. In Korea, insurance coverage of ultrasound examination has been gradually expanding in accordance with measures to enhance Korean National Insurance Coverage since 2017 to 2021, and which will continue until 2021. Full coverage of health insurance for POCUS in the emergency and critical care areas was implemented in July 2019. The National Health Insurance Act classified POCUS as a single or multiple-targeted ultrasound examination (STU vs. MTU). STU scans are conducted of one organ at a time, while MTU includes scanning of multiple organs simultaneously to determine each clinical situation. POCUS can be performed even if a diagnostic ultrasound examination is conducted, based on the physician's decision. However, the Health Insurance Review and Assessment Service plans to monitor the prescription status of whether the POCUS and diagnostic ultrasound examinations are prescribed simultaneously and repeatedly. Additionally, MTU is allowed only in cases of trauma, cardiac arrest, shock, chest pain, and dyspnea and should be performed by a qualified physician. Although physicians should scan all parts of the chest, heart, and abdomen when they prescribe MTU, they are not required to record all findings in the medical record. Therefore, appropriate prescription, application, and recording of POCUS are needed to enhance the quality of patient care and avoid unnecessary cut of medical budget spending. The present article provides background and clinical guidance for POCUS based on the implementation of full health insurance coverage for POCUS that began in July 2019 in Korea.

Abstract
BACKGROUND Both the interest and actual extent of use of point-of-care ultrasound, PoCUS, among general practitioners or family physicians are increasing and training is also increasingly implemented in residency programs. However, the amount of research within the field is still rather limited compared to what is seen within other specialties in which it has become more established, such as in the specialty of emergency medicine. An assumption is made that what is relevant for emergency medicine physicians and their populations is also relevant to the general practitioner, as both groups are generalists working in unselected populations. This systematic review aims to examine the extent of use and to identify clinical studies on the use of PoCUS by either general practitioners or emergency physicians on indications that are relevant for the former, both in their daily practice and in out-of-hours services. METHODS Systematic searches were done in PubMed/MEDLINE using terms related to general practice, emergency medicine, and ultrasound. RESULTS On the extent of use, we identified 19 articles, as well as 26 meta-analyses and 168 primary studies on the clinical use of PoCUS. We found variable, but generally low, use among general practitioners, while it seems to be thoroughly established in emergency medicine in North America, and increasingly also in the rest of the world. In terms of clinical studies, most were on diagnostic accuracy, and most organ systems were studied; the heart, lungs/thorax, vessels, abdominal and pelvic organs, obstetric ultrasound, the eye, soft tissue, and the musculoskeletal system. The studies found in general either high sensitivity or high specificity for the particular test studied, and in some cases high total accuracy and superiority to other established diagnostic imaging modalities. PoCUS also showed faster time to diagnosis and change in management in some studies. CONCLUSION Our review shows that generalists can, given a certain level of pre-test probability, safely use PoCUS in a wide range of clinical settings to aid diagnosis and better the care of their patients.

Abstract
BACKGROUNDS Hand fractures are the second most common upper-extremity fractures. The standard X-ray has shortcomings, such as exposure to radiation. Ultrasound has been reported as an alternative method of detecting hand fractures. In this study, we used meta-analysis to assess the diagnostic value of ultrasound for hand fractures. METHODS Web of Science, PubMed, Embase, and Cochrane Library databases were searched for relative citations up to June 2019. The pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), area under the summary receiver operating characteristic curve (AUC), and summary receiver operating characteristic (SROC) curve were estimated. RESULTS Seven studies including 842 participants (845 examined hands) met our inclusion criteria. The pooled sensitivity, specificity, PLR, and NLR of ultrasound for detecting hand fractures were 91%, 96%, 20.66, and 0.09, respectively. The pooled DOR was 231.17, indicating a very powerful diagnostic ability of ultrasound. Meta-regression showed that there was no heterogeneity with respect to age, cut-off, the performer of the ultrasound, and the types of hand fractures. CONCLUSIONS Our results showed that ultrasound had an excellent diagnostic value for hand fractures. In clinic, we proposed using ultrasound as a first-line and radiation-free modality in detecting hand fractures, including phalanx and metacarpal fractures.
