Item does not contain fulltext, Background: The objective of this study was to determine the association between sex and outcome among severely injured patients who were admitted in severe shock. Methods: A retrospective multicenter study was performed in trauma patients (Injury Severity Score (ISS) ≥ 16) aged ≥ 16 presenting with severe shock (Shock Index > 1.3) over a 4-year period. To determine if sex was associated with mortality, Intensive Care Unit (ICU) admission, mechanical ventilation, blood transfusion and in-hospital complications, multivariable logistic regressions were performed. Results: In total, 189 patients were admitted to the Emergency Department in severe shock. Multivariable logistic regression analysis showed that female sex was independently associated with a decreased likelihood of acute kidney injury (OR 0.184; 95% CI 0.041-0.823; p = 0.041) compared to the male sex. A significant association between female sex and mortality, ICU admission, mechanical ventilation, other complications and packed red blood cells transfusion after admission could not be confirmed. Conclusion: Female trauma patients in severe shock were significantly less likely to develop AKI during hospital stay. These results could suggest that female trauma patients may manifest a better-preserved physiologic response to severe shock when compared to their male counterparts. Prospective studies with a larger study population are warranted.

METHODS: A multicentre cross-sectional study was performed in 170 patients who were treated nonoperatively for an acetabular fracture in three level 1 trauma centres. Using the post-injury diagnostic CT scan, the maximum gap and step-off values in the weightbearing dome were digitally measured by two trauma surgeons. Native hip survival was reported using Kaplan-Meier curves. Predictors for conversion to THA were determined using Cox regression analysis. RESULTS: Of 170 patients, 22 (13%) subsequently received a THA. Native hip survival in patients with a step-off ≤ 2 mm, > 2 to 4 mm, or > 4 mm differed at five-year follow-up (respectively: 94% vs 70% vs 74%). Native hip survival in patients with a gap ≤ 2 mm, > 2 to 4 mm, or > 4 mm differed at five-year follow-up (respectively: 100% vs 84% vs 78%). Step-off displacement > 2 mm (> 2 to 4 mm hazard ratio (HR) 4.9, > 4 mm HR 5.6) and age > 60 years (HR 2.9) were independent predictors for conversion to THA at follow-up. CONCLUSION: Patients with minimally displaced acetabular fractures who opt for nonoperative fracture treatment may be informed that fracture displacement (e.g. gap and step-off) up to 2 mm, as measured on CT images, results in limited risk on conversion to THA. Step-off ≥ 2 mm and age > 60 years are predictors for conversion to THA and can be helpful in the shared decision-making process.

Background: Tibial shaft fractures (TSFs) are among the most common long bone injuries often resulting from high-energy trauma. To date, musculoskeletal complications such as fracture-related infection (FRI) and compromised fracture healing following fracture fixation of these injuries are still prevalent. The relatively high complication rates prove that, despite advances in modern fracture care, the management of TSFs remains a challenge even in the hands of experienced surgeons. Therefore, the Fracture-Related Outcome Study for operatively treated Tibia shaft fractures (F.R.O.S.T.) aims at creating a registry that enables data mining to gather detailed information to support future clinical decision-making regarding the management of TSF’s. Methods: This prospective, international, multicenter, observational registry for TSFs was recently developed. Recruitment started in 2019 and is planned to take 36 months, seeking to enroll a minimum of 1000 patients. The study protocol does not influence the clinical decision-making procedure, implant choice, or surgical/imaging techniques; these are being performed as per local hospital standard of care. Data collected in this registry include injury specifics, treatment details, clinical outcomes (e.g., FRI), patient-reported outcomes, and procedure- or implant-related adverse events. The minimum follow up is 12 months. Discussion: Although over the past decades, multiple high-quality studies have addressed individual research questions related to the outcome of TSFs, knowledge gaps remain. The scarcity of data calls for an international high-quality, population-based registry. Creating such a database could optimize strategies intended to prevent severe musculoskeletal complications. The main purpose of the F.R.O.S.T registry is to evaluate the association between different treatment strategies and patient outcomes. It will address not only operative techniques and implant materials but also perioperative preventive measu

Objectives: The primary aim of this study was to evaluate the number of patients reported to a hospital with injuries from consumer fireworks in the months December–January in the past 10 years, and to describe the association between the type of fireworks, injury pattern, treatment, and permanent impairment. Methods: A multicenter, retrospective, observational case series. Patients were selected from two hospitals in the Southwest Netherlands: a level 1 trauma center and a specialized burn center. All patients with any fireworks-related injuries treated between December 1 and January 31, during 2007 (December) to 2017 (January), were eligible for participation. The primary outcome was the number of patients with any type of injury caused by fireworks. The secondary outcome measures were patient and injury characteristics, treatment details, and whole person impairment (WPI). The percentage WPI expresses a patient’s degree of permanent impairments as a result of fireworks-related injuries. Results: Of the 297 eligible patients, 272 patients were included. From 2007 to 2017, between 21 and 40 patients were treated, and no clear increase or decrease was observed in the number of patients and in the number of patients per type of fireworks. Explosive fireworks mainly caused upper extremity (N = 65; 68%) injuries, while rockets (N = 24; 41%) and aerials (N = 7; 41%) mainly affected the head/neck. Decorative fireworks predominantly resulted in burns (N = 82; 68%), and explosive fireworks in soft tissue lacerations (N = 24; 25%), fractures (N = 16; 17%), and amputations (N = 14; 15%). Patients injured by explosive and homemade fireworks were most often admitted to a hospital (respectively N = 24; 36% and N = 12; 80%), and resulted in the highest proportion undergoing surgical procedures (respectively N = 22; 33% and N = 7; 47%). WPI found in this study was between 0 to 95%, with a median of 0%. In 34 (14%) patients, the injuries resulted in a WPI of ≥1%, mostly as a resul

Summary:Fracture-related infection (FRI) is a severe complication after bone injury and can pose a serious diagnostic challenge. Overall, there is a limited amount of scientific evidence regarding diagnostic criteria for FRI. For this reason, the AO Foundation and the European Bone and Joint Infection Society proposed a consensus definition for FRI to standardize the diagnostic criteria and improve the quality of patient care and applicability of future studies regarding this condition. The aim of this article was to summarize the available evidence and provide recommendations for the diagnosis of FRI. For this purpose, the FRI consensus definition will be discussed together with a proposal for an update based on the available evidence relating to the diagnostic value of clinical parameters, serum inflammatory markers, imaging modalities, tissue and sonication fluid sampling, molecular biology techniques, and histopathological examination. Second, recommendations on microbiology specimen sampling and laboratory operating procedures relevant to FRI will be provided.Level of Evidence:Diagnostic Level V. See Instructions for Authors for a complete description of levels of evidence.

Objective: Hip fractures in frail elderly patients are associated with significant mortality and morbidity. Surgery remains the predominant treatment of choice, despite the poor prognosis. Limited research has been done with regards to nonoperative management of frail elderly patients with a hip fracture and therefore the natural course is relatively unknown. This systematic review aimed to provide an overview of the prognosis of nonoperative management in frail elderly patients with a hip fracture in terms of mortality, complications, mobility, and quality of life (QoL). Design: A systematic review of the literature was conducted in PubMed, EMBASE, and Cochrane Central. In addition, a meta-analysis was performed. The primary outcome measurement was 30-days mortality. Results: A total of 4,318 studies were screened. In total eighteen studies matched the eligibility criteria; with low to moderate quality. Approximately two-thirds of the patients were managed nonoperatively due to medical reasons and one-third due to non-medical reasons. Pooled mortality rates after 30 days, six months and one year were 36%, 46%, and 60%, respectively. 33% of the patients developed in-hospital complications. At six months post trauma, 9.6% of the patients were able to mobilize. Data on quality of life (QoL), functional outcome, pain, comfort during nursing care, and costs were not reported. Conclusion

BACKGROUND With implementation of trauma systems, a level of trauma care classification was introduced. Use of such a system has been linked to significant improvements in survival and other outcomes. OBJECTIVES The aim of this study was assessing the association between level of trauma care and fatal and nonfatal outcome measures for general and major trauma (MT) populations. METHODS A systematic literature search was conducted using six electronic databases up to December 18, 2019. Studies comparing mortality or nonfatal outcomes between different levels of trauma care in general and MT populations (preferably Injury Severity Score of >15) were included. Two independent reviewers performed selection of relevant studies, data extraction, and a quality assessment of included articles. With a random-effects meta-analysis, adjusted and unadjusted pooled effect sizes were calculated for level I versus non-level I trauma centers. RESULTS Twenty-two studies were included. Quality of the included st

The aim of this study was to provide a detailed overview of age and gender specific health care costs and costs due to lost productivity for hospital admitted patients with an isolated tibia shaft fracture in The Netherlands between 2008 and 2012. Injury cases and length of hospital stay were extracted from the National Medical Registration. Information on extramural health care and work absence were retrieved from a patient follow-up survey on health care use. Medical costs included ambulance care, inhospital care, general practitioner care, home care, physical therapy, and rehabilitation/nursing care. An incidence-based cost model was applied to calculate direct health care costs and lost productivity in 2012. Total direct health care costs for all patients admitted with a tibia shaft fracture (n = 1,635) were €13.6 million. Costs for productivity loss were € 23.0 million. Total costs (direct health care and lost productivity) per patient were highest for men aged 40-49 years mainly due to lost productivity, and for women aged > 80 years, due to high direct medical costs.

Background The aim of this work was to develop a three-dimensionally (3D) printed brace for the acute treatment of dorsally dislocated and correctly reduced distal radius fractures (DRF). The hypothesis was that a brace shaped to the mirror image of the contralateral (non-fractured) wrist will have an optimal anatomical fit, resulting in improved comfort and lower rates of secondary fracture displacement. Method Validation: the circumference of both wrists and comfort of the brace were studied in healthy volunteers and effectiveness of the brace was evaluated in an ex vivo fracture model. Clinical study: the brace was tested for comfort and effectiveness in patients with a well reduced unstable DRF. Results Validation: the circumference of both wrists may be different, the brace retained the reduction in the ex vivo fracture model and was well tolerated in the volunteers. Clinical study: in DRF patients comfort scores were lower and pain scores higher compared to the healthy volunteers. After 3 and 5 weeks all patients were independent in ADL according to the Katz-index. Posttraumatic swelling subsided in the first week. In two of the five patients secondary fracture dislocation occurred. Conclusions Treatment of a dislocated DRF in the acute setting (day one) with a custom-made 3D printed brace, anatomically modelled from a 3D scan of the contralateral wrist, is possible. Difference between both wrists and posttraumatic swelling must be adapted for. The high rate of secondary fracture displacement led to early discontinuation of the study and a small sample size.

Objective: To assess and quantify the effect of perioperative music on medication requirement, length of stay and costs in adult surgical patients. Summary Background Data: There is an increasing interest in nonpharmacological interventions to decrease opioid analgesics use, as they have significant adverse effects and opioid prescription rates have reached epidemic proportions. Previous studies have reported beneficial outcomes of perioperative music. Methods: A systematic literature search of 8 databases was performed from inception date to January 7, 2019. Randomized controlled trials investigating the effect of perioperative music on medication requirement, length of stay or costs in adult surgical patients were eligible. Meta-analysis was performed using random effect models, pooled standardized mean differences (SMD) were calculated with 95% confidence intervals (CI). This study was registered with PROSPERO (CRD42018093140) and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. Results: The literature search yielded 24

Background: The Disabilities of the Arm, Shoulder and Hand (DASH) instrument was developed to assess the disability experienced by patients with any musculoskeletal condition of the upper extremity and to monitor change in symptoms and upper-limb function over time. The 30 items are scored on a 5-point rating scale. The Dutch-language version of the DASH instrument (DASH-DLV) has been examined with the classical test theory in patients with a humeral shaft fracture. This study aimed to examine the DASH-DLV with a more rigorous and extensive analysis by applying the Rasch model. Methods: Data of 400 patients included in a multicenter, prospective study comparing operative and nonoperative treatment of adult patients with a humeral shaft fracture were used. The person-item map, item fit statistics, reliability, response category ordering, and dimensionality were examined. Raw data were converted to linear measures using the Rasch model. Results: The DASH-DLV showed a good fit to the Rasch model, except for item 26 (“Tingling [pins and needles]

In calcaneal fractures, Böhler's and Gissane's angles are considered important parameters to guide treatment strategy and provide prognostic information during follow-up visits. Therefore, lateral radiographs have to be accurate. The aim of this study was to evaluate the effect of craniocaudal and posteroanterior angular variations (i.e., simulate lower leg malposition) from the true lateral radiograph on Böhler's and Gissane's angles. In this radioanatomical study, 15 embalmed, skeletally mature, human anatomic lower limb specimens were used. Using predefined criteria, a true lateral radiograph (i.e., 0° angular variation) was obtained. Angular variations from this true lateral radiograph were made from –30° to +30° deviation in the craniocaudal and posteroanterior direction at 5° intervals. Böhler's and Gissane angles were independently assessed by 2 experienced trauma surgeons. Böhler's angle decreased with increasing caudal angular variations (maximum –4.3° deviation at –30°). With increasing of the posterior angular variations, Böhler's angle increased (maximum 5.0° deviation at +30°) from the true lateral radiograph, but all deviations were within the measurement error. The deviation of the angle of Gissane was most pronounced in the cranial direction, with the mean angle decreasing by –

Background: Little is known on early irreversible effects of increased intra-abdominal pressure (IAP). Therefore, timing of abdominal decompression among patients with abdominal compartment syndrome remains challenging. The study objective was to determine the relation between IAP and respiratory parameters, hemodynamic parameters, and early intestinal ischemia. Methods: Twenty-five anesthetized and ventilated male Sprague-Dawley rats were randomly assigned to five groups exposed to IAPs of 0, 5, 10, 15, or 20 mm Hg for 3 hours. Respiratory parameters, hemodynamic parameters, and serum albumin-cobalt binding (ACB) capacity as measure for systemic ischemia were determined. Intestines were processed for histopathology. Results: IAP was negatively associated with mean arterial pressure at 90 (Spearman correlation coefficient; Rs=-0.446, p=0.025) and 180 min (Rs=-0.466, p=0.019), oxygen saturation at 90 min (Rs=-0.673, p<0.001) and 180 min (Rs=-0.882, p<0.001), and pH value at 90 (Rs=-0.819, p<0.001) and 180 min (Rs=-0.934, p<0.001). There were no associations between IAP and lactate level or ACB capacity. No histological signs for intestinal ischemia were found. Discussion: Although increasing IAP was associated with respiratory and hemodynamic difficulties, no signs for intestinal ischemia were found. Level of evidence: Prognostic and epidemiologic study, level II.

Purpose: The aim of this systematic review was to compare knee pain and function after tibial nail insertion through an infrapatellar, semi-extended and suprapatellar technique. Methods: A search was carried out to identify articles with an exact description of the method used for insertion of the tibial nail and description of the outcome parameters (knee pain or function). Data on study design, population, rate and severity of anterior knee pain and function scores were extracted. Pooled rates and scores were calculated. Results: 67 studies with 3,499 patients were included. The pooled rate of patients with anterior knee pain was 38% (95% CI 32–44) after nail insertion through an infrapatellar approach and 10% (95% CI 1–26) after insertion through a suprapatellar approach. Pooled analysis was not possible for the semi-extended technique. Knee pain scores as measured by visual analogue score (0–10) ranged from 0.2 (95% CI − 0.1–0.5) for general knee pain to 3.7 (95% CI 1.3–6.1) for pain during kneeling. Pooled estimates for the Lysholm score were 87 points (range 77–97) for the infrapatellar technique and 85 points (range 82–85) for the suprapatellar technique. Iowa Knee scores were 94 (range 86–96) and Anterior Knee Pain Scale scores were 76 (range 75–80) after infrapatellar nail insertion. Discussion: Depending on the technique used, the proportion of patients with knee pain after tibial nailing varied between 10 and 38%. The actual measured knee pain scores were, however, surprisingly low. Knee function was good for both the infra- and suprapatellar technique.

Purpose: This systematic review determined the reported treatment strategies, their individual success rates, and other outcome parameters in the management of critical-sized bone defects in fracture-related infection (FRI) patients between 1990 and 2018. Methods: A systematic literature search on treatment and outcome of critical-sized bone defects in FRI was performed. Treatment strategies identified were, autologous cancellous grafts, autologous cancellous grafts combined with local antibiotics, the induced membrane technique, vascularized grafts, Ilizarov bone transport, and bone transport combined with local antibiotics. Outcomes were bone healing and infection eradication after primary surgical protocol and recurrence of FRI and amputations at the end of study period. Results: Fifty studies were included, describing 1530 patients, the tibia was affected in 82%. Mean age was 40 years (range 6–80), with predominantly male subjects (79%). Mean duration of infection was 17 months (range 1–624) and mean follow-up 51 months (range 6–126). After initial protocolized treatment, FRI was cured in 83% (95% CI 79–87) of all cases, increasing to 94% (95% CI 92–96) at the end of each individual study. Recurrence of infection was seen in 8% (95% CI 6–11) and amputation in 3% (95% CI 2–3). Final outcomes overlapped across treatment strategies. Conclusion: Results should be interpreted with caution due to the retrospective and observational design of most studies, the lack of clear classification systems, incomplete data reports, potential underreporting of adverse outcomes, and heterogeneity in patient series. A consensus on classification, treatment protocols, and outcome is needed to improve reliability of future studies.

Purpose: The aim of this study was to investigate current practice in the management of acromioclavicular joint dislocations in the Netherlands. Methods: A 36-item literature-based and expert consensus survey was developed. If available, one orthopaedic and one trauma surgeon for every hospital (n = 82) in the Netherlands was asked to complete the online questionnaire. Only complete data sets were included in the analysis. Descriptive analysis was performed using SPSS. Results: Of 149 invited surgeo

Objective People in the Netherlands are legally allowed to celebrate New Year's Eve with consumer fireworks. The aim of this study was to provide detailed information about the patient and injury characteristics, medical and societal costs, and clinical and functional outcome in patients with injuries resulting from this tradition. Methods A multicenter, prospective, observational case series performed in the Southwest Netherlands trauma region, which reflects 15% of the country and includes a level I trauma center, a specialized burn center, a specialized eye hospital, and 13 general hospitals. All patients with any injury caused by consumer fireworks, treated at a Dutch hospital between December 1, 2017 and January 31, 2018, were eligible for inclusion. Exclusion criteria were unknown contact information or insufficient understanding of Dutch or English language. The primary outcome measure was injury characteristics. Secondary outcome measures included treatment, direct medical and indirect societal costs, and clinical and functional outcome until one year after trauma. Results 54 out of 63 eligible patients agreed to participate in this study. The majority were males (N = 50; 93%), 50% were children below 16 years of age, and 46% were bystanders. Injuries were mainly located to the upper extremity or eyes, and were mostly burns (N = 38; 48%) of partial thickness (N = 32; 84%). Fifteen (28%) patients were admitted and 11 (20%) patients needed surgical treatment. The mean total costs per patient were 6,320 (95% CI 3,400 to 9,245). The most important cost category was hospital admission. Only few patients reported complaints in patient-reported quality of life and functional outcome after 12 months follow-up. Conclusion This study found that young males are most vulnerable for fireworks injuries and that most injuries consist of burns, located to the arm and hand, and eye injuries. On the long-term only few patients experienced r

Background: Despite improving survival of patients in prehospital traumatic cardiac arrest (TCA), initiation and/or discontinuation of resuscitation of TCA patients remains a subject of debate among prehospital emergency medical service providers. The aim of this study was to identify factors that influence decision making by prehospital emergency medical service providers during resuscitation of patients with TCA. Methods: Twenty-five semi-structured interviews were conducted with experienced ambulance nurses, HEMS nurses and HEMS physicians individually, followed by a focus group discussion. Participants had to be currently active in prehospital medicine in the Netherlands. Interviews were encoded for analysis using ATLAS.ti. Using qualitative analysis, different themes around decision making in TCA were identified. Results: Eight themes were identified as being important factors for decision making during prehospital TCA. These themes were: (1) factual information (e.g., electrocardiography rhythm or trauma mechanism); (2) fear of providing futile care or major impairment if return of spontaneous circulation was obtained; (3) potential organ donation; (4) patient age; (5) suspicion of attempted suicide; (6) presence of bystanders or family; (7) opinions of other team members; and (8) training and education. Several ambulance nurses reported they do not feel adequately supported by the current official national ambulance guidelines on TCA, nor did they feel sufficiently trained to perform pre-hospital interventions such as endotracheal intubation or needle thoracocentesis on these patients. Conclusion: Eight themes were identified as being important for decision making during prehospital TCA. While guidelines based on prognostic factors are important, it should be recognized that decision making in TCA is impacted by more than factual information alone. This should be reflected in educational programs and future guidelines.

Purpose: Myocardial contusion can be a life-threatening condition in patients who sustained blunt thoracic trauma. The diagnostic approach remains a subject of debate. The aim of this study was to determine the sensitiv

Purpose: Distal radius fractures are very common and account for approximately 17% of all fractures treated. Multiple treatment methods are available to treat these fractures, both operative and nonoperative. This study aimed at evaluating the functional and clinical outcomes after treatment of distal radius fractures with the IlluminOss® System in adult patients. Methods: A retrospective case series was performed in a single-level two-trauma center. All consecutive adult patients with a distal radius fracture, treated with the IlluminOss® System between 01 August 2012 and 15 August 2015, were included in this study. Baseline patient characteristics and clinical data were retrospectively extracted from the medical records. Radial inclination, volar/dorsal tilt, ulnar variance, and radial length were measured on the latest available standard radiographs. In addition, patients were prospectively subjected to physical examination and were asked to complete the Disabilities of the Arm, Shoulder, and Hand, Patient-Rated Wrist Evaluation, and Short Form-36 questionnaires. Results: Twenty-six patients with 31 distal radius fractures were included. The median age at time of trauma was 77 years and 96% were females. Five patients developed a total of seven complications. Due to persisting pain one reoperation was performed, removing a small prominent part of the implant. Both patient-reported outcome scores and radiographic results were good to excellent. Conclusions: The IlluminOss® System is a feasible option to treat distal radius fractures with seemingly good clinical and functional outcome. One out of seven complications required surgical intervention. These outcomes justify more detailed prospective research.

Purpose: The aim of this study was to compare the rate of first attempt success of endotracheal intubation performed by ambulance nurses in patients with a Glasgow Coma Scale (GCS) of 3 using video laryngoscopy versus direct laryngoscopy. Methods: A prospective cohort study was conducted in a single, independent ambulance service. Twenty of a total of 65 nurse-staffed ambulances were equipped with a video laryngoscope; a classic direct laryngoscope (Macintosh) was available on all 65 ambulances. The primary outcome was first attempt success of the intubation. Secondary outcomes were overall success, time needed for intubation, adverse events, technical or environmental issues encountered, and return of spontaneous circulation (ROSC). Ambulance nurses were asked if the intubation device had affected the outcome of the intubation. Results: The first attempt success rate in the video laryngoscopy group [53 of 93 attempts (5
