RESUMEN
BACKGROUND: Conventional radiographs and clinical reassessment are considered guides in managing clinically suspected scaphoid fractures. This is a unique study as it assessed the value of conventional radiographs and clinical reassessment in a cohort of patients, all of whom underwent additional imaging, regardless of the outcome of conventional radiographs and clinical reassessment. QUESTIONS/PURPOSES: (1) What is the diagnostic performance of conventional radiographs in patients with a clinically suspected scaphoid fracture compared with high-resolution peripheral quantitative CT (HR-pQCT)? (2) What is the diagnostic performance of clinical reassessment in patients with a clinically suspected scaphoid fracture compared with HR-pQCT? (3) What is the diagnostic performance of conventional radiographs and clinical reassessment combined compared with HR-pQCT? METHODS: Between December 2017 and October 2018, 162 patients with a clinically suspected scaphoid fracture presented to the emergency department (ED). Forty-six patients were excluded and another 25 were not willing or able to participate, which resulted in 91 included patients. All patients underwent conventional radiography in the ED and clinical reassessment 7 to 14 days later, together with CT and HR-pQCT. The diagnostic performance characteristics and accuracy of conventional radiographs and clinical reassessment were compared with those of HR-pQCT for the diagnosis of fractures since this was proven to be superior to CT scaphoid fracture detection. The cohort included 45 men and 46 women with a median (IQR) age of 52 years (29 to 67). Twenty-four patients with a median age of 44 years (35 to 65) were diagnosed with a scaphoid fracture on HR-pQCT. RESULTS: When compared with HR-pQCT, conventional radiographs alone had a sensitivity of 67% (95% CI 45% to 84%), specificity of 85% (95% CI 74% to 93%), positive predictive value (PPV) of 62% (95% CI 46% to 75%), negative predictive value (NPV) of 88% (95% CI 80% to 93%), and a positive and negative likelihood ratio (LR) of 4.5 (95% CI 2.4 to 8.5) and 0.4 (95% CI 0.2 to 0.7), respectively. Compared with HR-pQCT, clinical reassessment alone resulted in a sensitivity of 58% (95% CI 37% to 78%), specificity of 42% (95% CI 30% to 54%), PPV of 26% (95% CI 19% to 35%), NPV of 74% (95% CI 62% to 83%), as well as a positive and negative LR of 1.0 (95% CI 0.7 to 1.5) and 1.0 (95% CI 0.6 to 1.7), respectively. Combining clinical examination with conventional radiography produced a sensitivity of 50% (95% CI 29% to 71%), specificity of 91% (95% CI 82% to 97%), PPV of 67% (95% CI 46% to 83%), NPV of 84% (95% CI 77% to 88%), as well as a positive and negative LR of 5.6 (95% CI 2.4 to 13.2) and 0.6 (95% CI 0.4 to 0.8), respectively. CONCLUSION: The accuracy of conventional radiographs (80% compared with HR-pQCT) and clinical reassessment (46% compared with HR-pQCT) indicate that the value of clinical reassessment is limited in diagnosing scaphoid fractures and cannot be considered directive in managing scaphoid fractures. The combination of conventional radiographs and clinical reassessment does not increase the accuracy of these diagnostic tests compared with the accuracy of conventional radiographs alone and is therefore also limited in diagnosing scaphoid fractures. LEVEL OF EVIDENCE: Level II, diagnostic study.

Celiac disease (CD) is a known risk factor for osteoporosis and fractures. The prevalence of CD in patients with a recent fracture is unknown. We therefore systematically screened patients at a fracture liaison service (FLS) to study the prevalence of CD. Patients with a recent fracture aged ≥ 50 years were invited to VieCuri Medical Center's FLS. In FLS attendees, bone mineral density (BMD) and laboratory evaluation for metabolic bone disorders and serological screening for CD was systematically evaluated. If serologic testing for CD was positive, duodenal biopsies were performed to confirm the diagnosis CD. Data were collected in 1042 consecutive FLS attendees. Median age was 66 years (Interquartile range (IQR) 15), 27.6% had a major and 6.9% a hip fracture, 26.4% had osteoporosis and 50.8% osteopenia. Prevalent vertebral fractures were found in 29.1%. CD was already diagnosed in two patients (0.19%), one still had a positive serology. Three other patients (0.29%) had a positive serology for CD (one with gastro-intestinal complaints). In two of them, CD was confirmed by duodenal histology (0.19%) and one refused further evaluation. The prevalence of biopsy-proven CD was therefore 0.38% (4/1042) of which 0.19% (2/1042) was newly diagnosed. The prevalence of CD in patients with a recent fracture at the FLS was 0.38% and within the range of reported prevalences in the Western-European population (0.33-1.5%). Newly diagnosed CD was only found in 0.19%. Therefore, standard screening for CD in FLS patients is not recommended.

We present a relatively rare clinical presentation of herniation of lung parenchyma. In our case, the patient suffered multiple rib fractures, with an intercostal herniation of lung tissue after a trauma. We opted for a conservative treatment, given the clinical presentation, and the absence of incarceration or strangulation of the pulmonary tissue. In the absence of clear guidelines for this rare presentation, current treatment can be conservative or surgical, depending on the clinical presentation.

BACKGROUND: Immobilization of the lower leg is associated with venous thromboembolism (VTE). Low molecular weight heparin (LMWH) is an anticoagulant treatment which might be used in adult patients with lower-leg immobilization to prevent deep venous thrombosis (DVT) and its complications. This is an update of the review first published in 2008. OBJECTIVES: To assess the effectiveness of low molecular weight heparin for the prevention of venous thromboembolism in patients with lower-leg immobilization in an ambulant setting. SEARCH METHODS: For this update the Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Specialised Register (last searched June 2013) and CENTRAL (2013, Issue 5). SELECTION CRITERIA: Randomized controlled trials (RCTs) and controlled clinical trials (CCTs) that described thromboprophylaxis by means of LMWH compared with no prophylaxis or placebo in adult patients with lower-leg immobilization. Immobilization was by means of a plaster cast or brace. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial quality and extracted data. The review authors contacted the trial authors for additional information if required. Statistical analysis was carried out using Review Manager (RevMan 5). MAIN RESULTS: We included six RCTs fulfilling the above criteria with a total of 1490 patients. We found an incidence of VTE ranging from 4.3% to 40% in patients who had a leg injury that had been immobilized in a plaster cast or a brace for at least one week and who received no prophylaxis, or placebo. This number was significantly lower in patients who received daily subcutaneous injections of LMWH during immobilization (event rates ranging from 0% to 37%; odds ratio (OR) 0.49; fixed 95% confidence interval (CI) 0.34 to 0.72; with minimal evidence of heterogeneity with an I(2) of 20%, P = 0. 29). Comparable results were seen in the following subcategories: operated patients, conservatively treated patients, patients with fractures, patients with soft-tissue injuries, patients with proximal thrombosis, patients with distal thrombosis and patients with below-knee casts. Complications of major bleeding events were extremely rare (0.3%) and there were no reports of heparin-induced thrombocytopenia. AUTHORS' CONCLUSIONS: Use of LMWH in outpatients significantly reduces VTE when immobilization of the lower leg is required.

Background: Currently, invasive dynamic intracompartmental pressure (ICP) measurements are considered the gold standard for diagnosis of chronic exertional compartment syndrome (CECS). During recent years, different noninvasive imaging modalities have been presented as a possible replacement for ICP measurement. Purpose: To provide an overview of the current state of evidence and possibilities regarding noninvasive diagnostic methods for CECS. Study Design: Scoping review; Level of evidence, 4. Methods: The PubMed (MEDLINE) and Embase databases were searched using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Full-text articles were included if they reported on noninvasive diagnostic methods for CECS, included ≥5 patients with CECS, and were published between 1994 and 2022. Articles not written in English were excluded. Systematic reviews, letters to the editor, and case reports were not eligible for inclusion. Out of 961 articles identified in the initial search, 25 studies (N = 1257 participants) were included. Risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies-Comparative (QUADAS-C) tool for comparative studies and the QUADAS-2 tool for noncomparative studies. Narrative synthesis was used to present results. Results: The level of evidence for the 25 studies ranged from 2 to 4. Four studies were classified as having a low risk of bias, 21 studies were classified as being at risk of bias. The following noninvasive diagnostic tools for CECS were reported: magnetic resonance imaging/diffusion tensor imaging (n = 8), near-infrared spectroscopy (n = 6), electromyography (n = 4), single-photon emission computed tomography (n = 5), ultrasound (n = 2), myotonometry (n=1) and predictive clinical model (n = 1). There was insufficient evidence in the literature to support the use of any of these noninvasive diagnostic tools as a gold standard for CECS. Conclusion: Despite the need to replace the controversial use of ICP for the diagnosis of CECS, our review indicated a lack of validity on all discussed noninvasive diagnostic tools as a replacement.
RESUMEN
OBJECTIVE: In the Netherlands, out-of-hours General Practice Cooperatives (GPCs) increasingly collaborate with Emergency Departments (EDs) to form an Emergency Care Access Point (ECAP). ECAPs aim to decrease the number of low-urgent ED attendances, of which many compromise minor traumatic injuries. In this study, we evaluated the impact of ECAP implementation on the incidence of minor traumatic injuries in the ED. METHODS: We evaluated a total of 2772 ED patients who presented with a minor traumatic injury (categorized into traumatic wounds and isolated extremity injuries) 1 year before and 1 year after ECAP implementation. We compared patient characteristics, throughput, diagnosis, treatment and follow-up before and after ECAP implementation. RESULTS: ECAP implementation was associated with a reduction in ED volume for minor traumatic injuries: -12.4% for isolated extremity injuries (1249 vs. 1094) and -74.6% for traumatic wounds (342 vs. 87). Multivariable logistic regression analysis controlling for patient characteristics showed that ECAP implementation was associated with higher rates of substantial injuries in the ED (OR 1.20, 95% CI = 1.01-1.43), and more patients requiring outpatient follow-up. CONCLUSION: Implementation of an ECAP was associated with a reduction of ED utilization by patients with minor traumatic injuries, traumatic wounds in particular. This healthcare intervention may therefore help to reduce ED utilization for low-urgent complaints.

RATIONALE, AIMS AND OBJECTIVES: Low-urgent Emergency Department (ED) attendances are a known contributing factor to ED crowding. In the Netherlands, general practitioners (GPs) have direct access to radiology facilities during office hours. Patients with radiographically confirmed traumatic injuries are subsequently referred to the ED. We analysed these ED trauma patients' characteristics, provided treatments and ED discharge diagnoses to identify the possibility of alternative care pathways. METHODS: Single-centre retrospective observational study of trauma patients referred to the ED by the radiology department during office hours (January 2017-December 2017). Data were obtained from patient records. Descriptive statistics were used to analyse the extracted data. RESULTS: A total of 662 patients were included. The median age was 42 years (range: 1-100, interquartile range (IQR): 15-63) and patients presented to the ED with a median delay of 1 day (range: 0-112 days, IQR: 0-5). Most patients were referred for injuries involving the upper extremities (61.5%) and lower extremities (30%). A total of 48 additional diagnoses were made in the ED. The majority of injuries was classified as 'minor' (29.5%) or 'moderate' (68.3%) on the Abbreviated Injury Scale (AIS). The median length of stay in the ED was 65 min (range: 7-297 min, IQR: 43-102). CONCLUSION: Most patients presented with low acuity injuries and often with a notable delay to the ED. This suggests that the majority of these patients do not necessarily need ED treatment, which may provide an opportunity to counter ED crowding.

High-resolution peripheral quantitative CT (HR-pQCT) enables quantitative assessment of distal radius fracture healing. In previous studies, lower-mineralized tissue formation was observed on HR-pQCT scans, starting early during healing, but the contribution of this tissue to the stiffness of distal radius fractures is unknown. Therefore, the aim of this study was to investigate the contribution of lower-mineralized tissue to the stiffness of fractured distal radii during the first twelve weeks of healing. We did so by combining the results from two series of micro-finite element (µFE-) models obtained using different density thresholds for bone segmentation. Forty-five postmenopausal women with a conservatively-treated distal radius fracture had HR-pQCT scans of their fractured radius at baseline (BL; 1-2 weeks post-fracture), 3-4 weeks, 6-8 weeks, and 12 weeks post-fracture. Compression stiffness (S) was computed using two series of µFE-models from the scans: one series (Msingle) included only higher-mineralized tissue (>320 mg HA/cm3), and one series (Mdual) differentiated between lower-mineralized tissue (200-320 mg HA/cm3) and higher-mineralized tissue. µFE-elements were assigned a Young's Modulus of 10 GPa (higher-mineralized tissue) or 5 GPa (lower-mineralized tissue), and an axial compression test to 1 % strain was simulated. The contribution of the lower-mineralized tissue to S was quantified as the ratio Sdual/Ssingle. Changes during healing were quantified using linear mixed effects models and expressed as estimated marginal means (EMMs) with 95 %-confidence intervals (95 %-CI). Median time to cast removal was 5.0 (IQR: 1.1) weeks. Sdual and Ssingle gradually increased during healing to a significantly higher value than BL at 12 weeks post-fracture (both p < 0.0001). In contrast, Sdual/Ssingle was significantly higher than BL at 3-4 weeks post-fracture (p = 0.0010), remained significantly higher at 6-8 weeks post-fracture (p < 0.0001), and then decreased to BL-values at the 12-week visit. EMMs ranged between 1.05 (95 %-CI: 1.04-1.06) and 1.08 (95 %-CI: 1.07-1.10). To conclude, combining stiffness results from two series of µFE-models obtained using single- and dual-threshold segmentation enables quantification of the contribution of lower-mineralized tissue to the stiffness of distal radius fractures during healing. This contribution is minor but changes significantly around the time of cast removal. Its course and timing during healing may be clinically relevant. Quantification of the contribution of lower-mineralized tissue to stiffness gives a more complete impression of strength recovery post-fracture than the evaluation of stiffness using a single series of µFE-models.

BACKGROUND: Fractures of the shaft of the humerus account for 1% to 3% of all fractures in adults. The management of these fractures, including surgical intervention, varies widely. OBJECTIVES: To assess and compare the effects of surgical versus non-surgical intervention for non-pathological fractures of the humeral shaft in adults. SEARCH METHODS: We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, trial registers, and bibliographies of trial reports. The full search was conducted in October 2011. SELECTION CRITERIA: Considered for inclusion were all randomised and quasi-randomised (method of allocating participants to a treatment which is not strictly random; e.g. by date of birth, hospital record number or alternation) controlled trials that compared surgical with non-surgical intervention for humeral shaft fractures in adults. DATA COLLECTION AND ANALYSIS: Two authors independently selected and assessed potential eligible studies for inclusion. MAIN RESULTS: We found six completed studies that appeared to meet our inclusion criteria. After scrutiny, we excluded all six studies: five were retrospective studies and one was a prospective study without randomisation. We identified three potentially eligible ongoing studies, two of which involve randomisation of treatment allocation and one, which we excluded, that does not. AUTHORS' CONCLUSIONS: There is no evidence available from randomised controlled trials to ascertain whether surgical intervention of humeral shaft fractures gives a better or worse outcome than no surgery. Sufficiently powered good quality multi-centre randomised controlled trials comparing surgical versus non-surgical interventions for treating humeral shaft fractures in adults are needed. It is likely that the results from the two ongoing randomised trials on this topic will help inform practice in due course.

OBJECTIVE: As a result of an aging population, mobility scooter use is increasing in Western countries. Consequently, an increase in mobility scooter-related injuries (MSRIs) is observed. Yet there is a paucity of studies in the literature assessing MSRIs. The purpose of this study was to investigate mechanism, severity, and localization of injury of MSRIs in the emergency department (ED) of a Dutch level 2 trauma center over a 9-year period. METHODS: This was a retrospective study of MSRIs in the ED of a teaching hospital in the Netherlands between January 2010 and December 2019. All patients with an MSRI were included, as long as they were the driver of the vehicle. Data were collected from electronic patient files. The primary outcomes were severity of injury, defined by the Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS), and mechanism and localization of injury. RESULTS: A total of 382 patients were identified. Of these, 208 (54.3%) were female and the median age was 76 years (interquartile range [IQR] = 67.0-83.0). The median Charlson Comorbidity Index (CCI) was 5.0 (IQR = 4.0-6.0). Three (0.8%) patients had an ISS ≥ 16. The median ISS was 3.0 (IQR = 1.0-5.0). The lower extremity was the most commonly injured body region (46.5%), followed by head injury (36.3%), external injury (31.6%), and upper extremity injuries. Fractures were most commonly observed in the shoulder (10.2%), hip (8.9%), and ankle (6.3%). Most crashes were single-vehicle accidents (87.2%) and the most common mechanism of injury was rollover of mobility scooter (49.3%). Almost half of the patients (44.1%) had a fracture and the admission rate was 28.2% with a median length of stay (LOS) of 10 days. Fifty (13.1%) patients required surgery, of which 58% were hip repair surgery. CONCLUSION: In this cohort of MSRIs, mobility scooter users had a median age of 76 years and severe comorbidity was common. Based on ISS, patients had a mild injury profile. However, the relatively high admission and surgery rates reflect the potential serious consequences of MSRIs and the obvious vulnerability of this population.

Forearm fractures such as distal radius fractures are traditionally treated with a plaster or synthetic cast. Patients commonly report inconvenience of the cast, skin problems, and occasionally radial sensory nerve numbness. A known issue with casting is that the rate of secondary dislocation is high. As an alternative to casts, personalized 3D-printed braces are increasingly used. This review provides an inventory of current developments and experience with 3D-printed forearm braces. Main focus was on the design requirements, materials used, technical requirements, and preclinical and clinical results. Review of 12 studies showed that all printed braces used an open design. Fused Deposition Modelling is most commonly used 3D-printing technique (seven studies) and polylactic acid is the most commonly used material (five studies). Clinical evaluation was done in six studies, mainly involving distal radius fractures, and generally showed a low complication rate and high patient satisfaction with the printed brace. Whether or not the results obtained with 3D-printed braces are superior to results after casting requires further studies.

Fracture liaison services (FLS) are considered to be the most effective organizational approach for secondary fracture prevention. In this study, we evaluated whether FLS care was associated with reduced subsequent fracture and mortality risk over 3 years of follow-up. In total, 8682 consecutive patients aged 50-90 years with a recent fracture were included. Before FLS introduction, regular fracture treatment procedures were followed (pre-FLS). After FLS introduction, patients were invited to the FLS and FLS attenders were assessed for osteoporosis, prevalent vertebral fractures, metabolic bone disorders, medication use, and fall risk, and treatment for fracture prevention was initiated according to Dutch guidelines. All fractures were radiographically confirmed and categorized into major/hip (pelvis, proximal humerus or tibia, vertebral, multiple rib, distal femur) and non-major/non-hip (all other fractures). Mortality risk was examined using age and sex adjusted Cox proportional hazard models. For subsequent fracture risk, Cox proportional hazard models were adjusted for age, sex, and competing mortality risk (subdistribution hazard [SHR] approach). The pre-FLS group consisted of 2530 patients (72% women), of whom 1188 (46.9%) had major/hip index fractures, the post-FLS group consisted of 6152 patients (69% women), of whom 2973 (48.3%) had major/hip index fractures. In patients with a non-major/non-hip fracture there was no difference in subsequent non-major/non-hip fracture risk or mortality between pre-FLS and post-FLS. In patients with a major/hip index fracture, mortality risk was lower post-FLS (hazard ratio [HR] 0.84; 95% confidence interval [CI], 0.73-0.96) and subsequent major/hip fracture risk was lower in the first 360 days after index fracture post-FLS compared to pre-FLS (SHR 0.67; 95% CI, 0.52-0.87). In conclusion, FLS care was associated with a lower mortality risk in the first 3 years and a lower subsequent major/hip fracture risk in the first year in patients with a major/hip index fracture but not in patients with a non-major/non-hip fracture. © 2022 The Authors.

OBJECTIVES: To evaluate the risk of subsequent fractures in patients who attended the Fracture Liaison Service (FLS), with and without incident falls after the index fracture. DESIGN: A 3-year prospective observational cohort study. SETTING: An outpatient FLS in the Netherlands. PARTICIPANTS: Patients aged 50+ years with a recent clinical fracture. OUTCOME MEASURES: Incident falls and subsequent fractures. RESULTS: The study included 488 patients (71.9% women, mean age: 64.6±8.6 years). During the 3-year follow-up, 959 falls had been ascertained in 296 patients (60.7%) (ie, fallers), and 60 subsequent fractures were ascertained in 53 patients (10.9%). Of the fractures, 47 (78.3%) were fall related, of which 25 (53.2%) were sustained at the first fall incident at a median of 34 weeks. An incident fall was associated with an approximately 9-fold (HR: 8.6, 95% CI 3.1 to 23.8) increase in the risk of subsequent fractures. CONCLUSION: These data suggest that subsequent fractures among patients on treatment prescribed in an FLS setting are common, and that an incident fall is a strong predictor of subsequent fracture risk. Immediate attention for fall risk could be beneficial in an FLS model of care. TRIAL REGISTRATION NUMBER: NL45707.072.13.

BACKGROUND: Acute appendicitis is one of the most common causes of acute abdominal pain. Present day treatment of choice for acute appendicitis is appendectomy, however complications are inherent to operative treatment. Though surgical appendectomy remains the standard treatment, several investigators have investigated conservative antibiotic treatment of acute appendicitis and reported good results. OBJECTIVES: Is antibiotic treatment as effective as surgical appendectomy (laparoscopic or open) in patients with acute appendicitis on recovery within two weeks, without major complications (including recurrence) within one year? SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 6, 2011); MEDLINE (until June 2011); EMBASE (until June 2011); Prospective Trial Registers (June 2011) and reference lists of articles. SELECTION CRITERIA: Randomised and quasi-randomised clinical trials (RCT and qRCT) comparing antibiotic treatment with appendectomy in patients with suspected appendicitis were included. Excluded were studies which primarily focused on the complications of acute appendicitis. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial quality and extracted data. The review authors contacted the trial authors for additional information if required. Statistical analysis was carried out using Review Manager and MetaAnalyst. A non-inferiority analysis was performed, comparing antibiotic treatment (ABT) to the gold standard (appendectomy). By consensus, a 20% margin of non-inferiority was considered clinically relevant. MAIN RESULTS: Five RCT's (901 patients) were assessed. In total 73.4% (95% CI 62.7 to 81.9) of patients who were treated with antibiotics and 97.4 (95% CI 94.4 to 98.8) patients who directly got an appendectomy were cured within two weeks without major complications (including recurrence) within one year. The lower 95% CI was 15.2% below the 20% margin for the primary outcome. AUTHORS' CONCLUSIONS: The upper bound of the 95% CI of ABT for cure within two weeks without major complications crosses the 20% margin of appendectomy, so the outcome is inconclusive. Also the quality of the studies was low to moderate, for that reason the results should be interpret with caution and definite conclusions cannot be made. Therefore we conclude that appendectomy remains the standard treatment for acute appendicitis. Antibiotic treatment might be used as an alternative treatment in a good quality RCT or in specific patients or conditions were surgery is contraindicated.

PURPOSE: To investigate the mechanisms and severity of injuries of e-bikers compared with conventional bicycle (CB) users at the emergency department (ED) of a level 2 trauma center in the Netherlands. METHODS: We performed a prospective observational study. All patients ≥ 16 years who presented at the ED with an e-bike or conventional bicycle accident were eligible for inclusion. Primary outcomes were mechanisms and severity of injury. Injury severity was defined by the abbreviated injury score and the injury severity score (ISS). Data were analyzed using SPSS (IBM version 24). RESULTS: A total of 78 e-bikers and 91 CB, were included. The mean age of the e-bikers was 66.9 ± 13.6 years (CB 45.2 ± 20.5 years, P < 0.001). The Charlson comorbidity index was higher in e-bikers (3.1 vs. 1.2, P < 0.001). Mechanism of injury and ISS did not differ between the groups (median ISS 4.0), even though two e-bikers were severely injured (ISS ≥ 16). Alcohol was consumed twice as frequently in CB-related injuries (40% vs. 19.2%, P < 0.01). CONCLUSION: In this cohort of bicycle injuries in the ED of a level 2 trauma center, e-bikers were older and had more comorbidities than CB users. Except for a higher rate of thoracic and soft-tissue trauma in e-bikers, no differences were found in the mechanism and severity of injury. While it is important to note that helmet use and alcohol avoidance have demonstrable health benefits for bicyclists, further studies to quantify these benefits are recommended.

Scaphoid fractures are difficult to diagnose with current imaging modalities. It is unknown whether the shape of the scaphoid bone, assessed by statistical shape modeling, can be used to differentiate between fractured and non-fractured bones. Therefore, the aim of this study was to investigate whether the presence of a scaphoid fracture is associated with shape modes of a statistical shape model (SSM). Forty-one high-resolution peripheral quantitative computed tomography (HR-pQCT) scans were available from patients with a clinically suspected scaphoid fracture of whom 15 patients had a scaphoid fracture. The scans showed no motion artefacts affecting bone shape. The scaphoid bones were semi-automatically contoured, and the contours were converted to triangular meshes. The meshes were registered, followed by principal component analysis to determine mean shape and shape modes describing shape variance. The first five out of the forty shape modes cumulatively explained 87.8% of the shape variance. Logistic regression analysis was used to study the association between shape modes and fracture presence. The regression models were used to classify the 41 scaphoid bones as fractured or non-fractured using a cut-off value that maximized the sum of sensitivity and specificity. The classification of the models was compared with fracture diagnosis on HR-pQCT. A regression model with four shape modes had an area under the ROC-curve of 72.3% and correctly classified 75.6% of the scaphoid bones (fractured: 60.0%, non-fractured: 84.6%). To conclude, fracture presence in patients with a clinically suspected scaphoid fracture appears to be associated with the shape of the scaphoid bone.

AIMS: Besides conventional radiographs, the use of MRI, CT, and bone scintigraphy is frequent in the diagnosis of a fracture of the scaphoid. However, which techniques give the best results remain unknown. The investigation of a new imaging technique initially requires an analysis of its precision. The primary aim of this study was to investigate the interobserver agreement of high-resolution peripheral quantitative CT (HR-pQCT) in the diagnosis of a scaphoid fracture. A secondary aim was to investigate the interobserver agreement for the presence of other fractures and for the classification of scaphoid fracture. METHODS: Two radiologists and two orthopaedic trauma surgeons evaluated HR-pQCT scans of 31 patients with a clinically-suspected scaphoid fracture. The observers were asked to determine the presence of a scaphoid or other fracture and to classify the scaphoid fracture based on the Herbert classification system. Fleiss kappa statistics were used to calculate the interobserver agreement for the diagnosis of a fracture. Intraclass correlation coefficients (ICCs) were used to assess the agreement for the classification of scaphoid fracture. RESULTS: A total of nine (29%) scaphoid fractures and 12 (39%) other fractures were diagnosed in 20 patients (65%) using HR-pQCT across the four observers. The interobserver agreement was 91% for the identification of a scaphoid fracture (95% confidence interval (CI) 0.76 to 1.00) and 80% for other fractures (95% CI 0.72 to 0.87). The mean ICC for the classification of a scaphoid fracture in the seven patients diagnosed with scaphoid fracture by all four observers was 73% (95% CI 0.42 to 0.94). CONCLUSION: We conclude that the diagnosis of scaphoid and other fractures is reliable when using HR-pQCT in patients with a clinically-suspected fracture.

BACKGROUND: Equestrian-related injuries (ERIs) are relatively severe compared with injuries in other popular sports. Previous studies on epidemiology of ERIs vary widely and mainly focus on incidence instead of severity of the injury. PURPOSE: The aim of this study was to determine incidence, mechanisms and severity of ERIs in two Dutch hospitals (level 1 and level 2 trauma centers) over a 5-year period. PATIENTS AND METHODS: All patients with ERIs who visited the emergency departments of VieCuri Medical Centre in Venlo and Maastricht University Medical Centre+ in Maastricht, The Netherlands, between July 2010 and June 2015 were retrospectively included. Clinical data were extracted from medical records. RESULTS: Most ERIs occurred in mounted riders (646 events; 68%); 94.9% of which involved a fall. Being kicked (42.5%) or trapped (30.1%) was the most common cause of injury in unmounted riders. Most frequently injured body parts were the upper extremities (43.8%) in mounted riders and lower extremities (40.5%) in the unmounted group. A relatively high percentage of facial injuries (9.7%) were found in the unmounted group. Seventeen per cent of all ERIs required admission. The median Injury Severity Score was 5 in the admitted population and 1 in the total population. CONCLUSION: Horseback riding is a risky activity. Prior studies particularly studied admitted patients in level 1 trauma centers outside of Europe and demonstrated a high risk of significant injury. However, our study demonstrates that these studies in selected groups might have overestimated the severity of ERIs in the general population.

Distal radius fractures (DRFs) occur in various complexity patterns among patients differing in age, gender, and bone mineral density (BMD). Our aim was to investigate the association of patient characteristics, BMD, bone microarchitecture, and bone strength with the pattern complexity of DRFs. In this study, 251 patients aged 50-90 years with a radiologically confirmed DRF who attended the Fracture Liaison Service of VieCuri Medical Centre, the Netherlands, between November 2013 and June 2016 were included. In all patients fracture risk factors and underling metabolic disorders were evaluated and BMD measurement with vertebral fractures assessment by dual-energy X-ray absorptiometry was performed. Radiographs of all DRFs were reviewed by two independent investigators to assess fracture pattern complexity according to the AO/OTA classification in extra-articular (A), partially articular (B), and complete articular (C) fractures. For this study, patients with A and C fractures were compared. Seventy-one patients were additionally assessed by high-resolution peripheral quantitative computed tomography. Compared to group A, mean age, the proportion of males, and current smokers were higher in group C, but BMD and prevalent vertebral fractures were not different. In univariate analyses, age, male gender, trabecular area, volumetric BMD (vBMD), and stiffness were associated with type C fractures. In multivariate analyses, only male gender (odds ratio (OR) 8.48 95% confidence interval (CI) 1.75-41.18, p = 0.008]) and age (OR 1.11 [95% CI 1.03-1.19, p = 0.007]) were significantly associated with DRF pattern complexity. In conclusion, our data demonstrate that age and gender, but not body mass index, BMD, bone microarchitecture, or strength were associated with pattern complexity of DRFs.© 2019 The Authors.

Patients with a low bone mineral density have an increased risk of cardiovascular diseases (CVD) and venous thromboembolic events (VTE). The aim of our retrospective chart review was to investigate the prevalence of CVD, VTE, hypertension (HT), and diabetes mellitus type 2 (DM2) in patients with a recent clinical fracture visiting the Fracture Liaison Service (FLS). Out of 3057 patients aged 50-90 years, 1359 consecutive patients, who agreed and were able to visit the FLS for fracture risk evaluation, were included (71.7% women; mean age 65.2 yrs). Based on medical history, 29.9% had a history of CVD (13.7%), VTE (1.7%), HT (14.9%), and DM2 (7.1%) or a combination. Their prevalence increased with age (21% in patients aged 50-59 years to 48% in patients aged >80 years) and was higher in men than in women (36% versus 27%), but independent of bone mineral density and fracture type. Careful evaluation of medical history with respect to these risk factors should be performed in patients with a recent clinical fracture before starting treatment with medications that increase the risk of VTE or cardiovascular events, such as raloxifene, strontium ranelate, or NSAIDs.
