In 1999 an inclusive trauma system was initiated in the Netherlands and a nationwide trauma registry, including all admitted trauma patients to every hospital, was started. The Dutch trauma system is run by trauma surgeons who treat both the truncal (visceral) and extremity injuries (fractures). In this comprehensive review based on previous published studies, data over the past 20 years from the central region of the Netherlands (Utrecht) was evaluated. It is demonstrated that the initiation of the trauma systems and the governance by the trauma surgeons led to a region-wide mortality reduction of 50% and a mortality reduction for the most severely injured of 75% in the level 1 trauma centre. Furthermore, major improvements were found in terms of efficiency, demonstrating the quality of the current system and its constructs such as the type of surgeon. Due to the major reduction in mortality over the past few years, the emphasis of trauma care evaluation shifts towards functional outcome of severely injured patients. For the upcoming years, centralisation of severely injured patients should also aim at the balance between skills in primary resuscitation and surgical stabilization versus longitudinal surgical involvement. Further centralisation to a limited number of level 1 trauma centres in the Netherlands is necessary to consolidate experience and knowledge for the trauma surgeon. The future trauma surgeon, as specialist for injured patients, should be able to provide the vast majority of trauma care in this system. For the remaining part, intramural, regional and national collaboration is essential

Recreational watercraft use is popular across the United States, and there is a high rate of injury associated with the use and misuse of these vehicles. Watercraft propeller injuries represent a particularly devastating mechanism of injury. We aim to describe and analyze the range of orthopaedic injuries sustained from a watercraft propeller with a particular focus on the mechanism, injury pattern, management, and complications associated with these unique, high-energy injuries. A retrospective review of 42 patients who sustained injuries from watercraft propeller that presented to a level 1 trauma center was performed. Data collected included patient demographics, mechanism of injury, surgical management, antibiotic use, and complications. Forty-two patients sustained 96 fractures. Ninety-one fractures (94.8%) were open and 5(5.2%) were closed. Twenty (20.8%) were of the upper extremity, 70(72.9%) were of the lower extremity, and 6(6.3%) were of the pelvic ring. The majority of open fractures were Gustilo–Anderson Type IIIA or greater (54, 59.3%). There were 9 total infections affecting 8 of 96 fracture sites (cumulative risk of 8.3%), and other complications included stiffness (3), heterotopic ossification (1), non-union (1), flap failure (1), DVT (2), PE (1), and systemic infection (1) for a total of 19 complications. Watercraft propellers often result in devastating injuries with high rates of morbidity. The high rate of open fractures and neurovascular injury, necessity for multiple surgeries, and extended length of hospital stay show the need for continued awareness about boat safety and the danger of propellers.

On occasion, advanced invasive procedures in pre-hospital care can be life saving. This study aimed to identify the contemporary use of these procedures on a regional doctor-led air ambulance unit, and to define the need, skill set and training requirements for a regional pre-hospital team in the UK. Mission data were recorded prospectively and the database reviewed to identify invasive procedures over a 76-month period. These cases were reviewed with indications, mechanism of injury, presence of cardiac arrest at any time point (±return of spontaneous circulation) and procedural failure or morbidity. Two hundred and thirty-five procedures were performed: 16 for injuries affecting the airway, 111 for breathing and 108 for circulation. Almost a third of patients in cardiac arrest regained spontaneous circulation. Procedures performed increased fivefold from 2003 to 2009, with a marked increase in the use of thoracostomy and intra-osseous access. Procedural failure or inadequacy was high with needle cricothyroidotomy, needle chest decompression and early intra-osseous access experience. A steady increase in the number of procedures was observed over time. Less invasive methods of airway and breathing support were frequently inadequate, though definitive surgical airway or chest decompression was effective each time it was performed. Thoracotomy was performed infrequently. There are implications for the training of pre-hospital doctors who work in the majority of the UK.

This study aimed to measure the preventive effect of seat belt on traumatic brain injury (TBI) and to compare the effect according to the crash severities and collision directions. Korea In-Depth Accident Study (KIDAS) has collected vehicle and demographic data on injured occupants involved in motor vehicle collisions (MVCs) who visited three emergency medical centers for calendar years 2011–2016. Primary and secondary end points were TBI (abbreviated injury score 2+) and in-hospital mortality. Crush extent (CE) was classified into 1–2, 3–4, 5–6, and 7–9 according to the crash severity. We calculated adjusted odds ratios (ORs) of seat belts and CE for study outcomes and developed an interaction model in each collision direction using multivariate logistic regression analysis. Of the 2,245 occupants who were injured in MVCs, 295 (13.1%) occupants sustained TBI. In univariate analysis, old age, unbelted status, lateral collision, and higher CE were factors associated with TBI in MVCs. Occupants with belted status was less likely to have TBI and in-hospital mortality compared with those with unbelted status [AORs (95% CI) 0.48 (0.37–0.62) and 0.49 (0.30–0.81), respectively]. In interaction analysis, preventive effects of seat belts on TBI from MVCs were retained within CE 5–6 in frontal MVCs and within CE 1–2 in near side lateral MVCs, and those of seat belts on in-hospital mortality were reserved within CE 3–4 in frontal and rollover MVCs. The preventive effects of seat belts on TBI and in-hospital mortality are preserved within a limited crash severity in each collision direction.

The use of three-dimensional printing models in medical practice has been booming recently and its application to orthopedic surgery is gaining popularity. When treating fractures by open reduction and internal fixation, potential benefits have been associated with the use of 3D printing models. This review aims to quantitatively analyze the effectiveness of using 3D printing models in fracture management. A structured systematic review was conducted, and multiple databases were searched using a combination of terms related to 3D printing in fracture management. The literature search was limited from inception to Nov 2020. Only comparative randomized studies were accepted for inclusion. Any software or material using 3D printing versus no technological assistance was included. All types of fracture treated by open reduction and internal fixation were included. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology was applied with the Joanna Briggs Institute’s critical appraisal tool used to assess the quality of the included studies. Quantitative analysis was performed. Based on 13 RCTs including 673 patients (325 and 348 in the 3D and control groups, respectively), the weighted effect size outcomes were as follows: (a) operative duration − 1.47 (95% CI = − 1.759 to − 1.182), (b) intraoperative blood loss − 1.41 (95% CI = − 1.792 to − 1.029), (c) fluoroscopy use − 1.25 (95% CI = − 1.637 to − 0.867), in favor of the 3D group. The weighted Odds ratio outcomes were: (a) overall good or excellent result 2.05 (95% CI = 1.119 to 3.845) and (b) anatomic fracture reduction 2.64 (95% CI = 1.150 to 6.051) in favor of the 3D group. The mean residual displacement and time to union showed no significant difference. The mean JBI appraisal tool score for the randomized studies was of 9, out of a maximum of 13. When compared to the non-use of 3D technology for open reduction and internal fixation of fractures, the review demonstrated evidence that 3D printing yielded significantly better perioperative results. Further studies are needed to evaluate the effect of 3D printing on union and long-term function. I.

To investigate patient-specific factors that predict Total Hip Replacement (THR) in patients with fracture neck of femur (NOF), fulfilling the National Institute of Health and Care Excellence (NICE) criteria. Hip fracture database from a district general hospital and university hospital was retrospectively reviewed to identify patients fulfilling NICE criteria for THR after fracture NOF. Patient demographics, Nottingham Hip Fracture score (NHFS), complications, re-operations, revision, 30 days and one-year mortality was obtained from patient-records. Independent predictors correlating with the outcome of surgery were identified. A logistic regression analysis was used to predict the type of surgery in these patients. A total of 230 (114 WMH and 116 MH) were identified; 133 (57.8 per-cent) received hip hemiarthroplasty (HA), and 97 (42.2 per-cent) received THR. Patients receiving THR (mean 73.5 years, 95% CI 72–74.8) were significantly younger in comparison to patients receiving HA (mean 81.7 years, 95% CI 80.5–82.8). A negative correlation is noted between NHFS and type of surgery (Pearson’s correlation − 0.537, p < 0.01), implying higher NHFS decreased the likelihood of receiving THR. Regression analysis showed NHFS (p-0.001) and walking ability (p-0.001) as significant predictors for the type of surgery (Nagelkerke R2-0.472). A log-rank test showed higher estimated survival time in patients with THR in comparison to HA (p-value 0.002). NHFS and walking ability can be used as an adjunct to the NICE criteria for selecting patients for THR after fracture NOF. Carefully selected patients treated with THR survive longer and have a better outcome in comparison to HA.

Proximal humeral fractures associated with vascular compromise are extremely rare in children. We describe the presentation, diagnosis and management of one such injury in a child.

Fragility fractures of the pelvis (FFP) are a clinical entity with an increasing significance in clinical practice. Little is known about the conditions, which influence decision making and outcome. Level I trauma center. Prospective assessment of selected parameters of patients, who were admitted with a FFP in a 2-year period. Fractures were classified in accordance with the Rommens and Hofmann classification. Living environment, level of autonomy (independent walking), type of treatment (conservative versus operative), type of surgical technique, European Quality of Life-5 Dimensions-5 Levels (EQ-5D-5L), Short Form-8 Physical Component Score (SF-8 PCS) and Short Form-8 Mental Component Score (SF-8 MCS), Barthel Index, Parker Mobility Score (PMS) and Numeric Rating Scale (NRS) were collected at primary presentation (t1), at discharge (t2) and after 3 (t3) and 12 months (t4). Length of hospital stay, in-hospital complications, surgery-related complications, new osteoporotic fractures and mortality rate within the first year were also registered. The key factors influencing the choice of therapy and outcome were looked for. 110 patients, 99 women (90%) and 11 men (10%), were included in the study. Their mean age was 79.2 years (SD 10 years). Fourteen patients had FFP type I (12.7%), 59 FFP type II (53.6%), 11 FFP type III (10%) and 26 FFP type IV fractures (23.6%). All patients with FFP type I were treated conservatively. 48 patients with FFP types II-IV were treated conservatively and 48 operatively. Patients, who got a conservative outpatient treatment first and were hospitalized later, had higher FFP fracture types at admission. Operatively treated patients were hospitalized at a median of 33.5 days after the beginning of complaints, whereas the median day of admission of the conservative group was the day of trauma (p < 0.001). The operatively treated patients were hospitalized in a worse clinical condition (SF-8 PCS, EQ-5D-5L, autonomy). Length of stay (LoS) of operatively treated patients was significantly longer than of conservatively treated (p < 0.001). There was a tendency to more in-hospital complications in the operative group (p = 0.059). The rate of surgery-related complications (8.3%) was low with only one revision needed. Selected outcome parameters improved during the observation period nearly reaching the level before FFP after 1 year. SF-8 PCS, Barthel index and rate of patients living home were higher in the operative group at t4. The improvement of autonomy (independent walking) between t1 and t4 was significant in the operated group (p = 0.04) but not in the conservative group (p = 0.96). One-year mortality rate was 11.7% with no difference between the fracture types. One-year mortality rate of conservatively treated patients with FFP type II-IV was 13.5% versus 6.9% in the operative group (p = 0.38). Conservative treatment is appropriate in patients with FFP type I as well as in patients with FFP type II, provided that the last ones are hospitalized immediately after the traumatic event. Surgical treatment is recommended in patients with higher fracture types, with delayed presentation or after unsuccessful conservative treatment. In the conservative and operative group, all selected parameters considerably improved between t1 and t4 with a steeper increase in the operative group. The rate of postoperative complications is low. The 1-year mortality rate is the lowest in the operative group. Surgical stabilization of FFP is safe and reliable provided it is performed with care and in the appropriate target group.

Traumatic spinal injury (TSI) encompasses a wide range of injuries affecting the spinal cord, nerve roots, bones, and soft tissues that result in pain, impaired mobility, paralysis, and death. There is some evidence suggesting that women may have different physiological responses to traumatic injury compared to men; therefore, this study aimed to investigate if there are any associations between sex and adverse outcomes following surgically managed isolated TSI. Using the 2013–2019 TQIP database, all adult patients with isolated TSI, defined as a spine AIS ≥ 2 with an AIS ≤ 1 in all other body regions, resulting from blunt force trauma requiring spinal surgery, were eligible for inclusion in the study. The association between the sex and in-hospital mortality as well as cardiopulmonary and venothromboembolic complications was determined by calculating the risk ratio (RR) after adjusting for potential confounding using inverse probability weighting. A total of 43,756 patients were included. After adjusting for potential confounders, female sex was associated with a 37% lower risk of in-hospital mortality [adjusted RR (95% CI): 0.63 (0.57–0.69), p < 0.001], a 27% lower risk of myocardial infarction [adjusted RR (95% CI): 0.73 (0.56–0.95), p = 0.021], a 37% lower risk of cardiac arrest [adjusted RR (95% CI): 0.63 (0.55–0.72), p < 0.001], a 34% lower risk of deep vein thrombosis [adjusted RR (95% CI): 0.66 (0.59–0.74), p < 0.001], a 45% lower risk of pulmonary embolism [adjusted RR (95% CI): 0.55 (0.46–0.65), p < 0.001], a 36% lower risk of acute respiratory distress syndrome [adjusted RR (95% CI): 0.64 (0.54–0.76), p < 0.001], a 34% lower risk of pneumonia [adjusted RR (95% CI): 0.66 (0.60–0.72), p < 0.001], and a 22% lower risk of surgical site infection [adjusted RR (95% CI): 0.78 (0.62–0.98), p < 0.032], compared to male sex. Female sex is associated with a significantly decreased risk of in-hospital mortality as well as cardiopulmonary and venothromboembolic complications following surgical management of traumatic spinal injuries. Further studies are needed to elucidate the cause of these differences.
