Long-term musculoskeletal function after Open Pelvic ring fractures in Children (OPEC); a multicentre, retrospective case series with follow-up measurement.

Background: The proportion of Open Pelvic fractures in the paediatric population is relatively high. While operative fixation is the primary approach for managing Open Pelvic fractures in adults, there is limited literature on treatment outcomes in Children, particularly regarding long-term musculoskeletal, neurological, and urogenital function. Methods: This multicentre case series included paediatric patients (<18 years old) with Open Pelvic ring fractures treated at one of two major trauma centres in the Netherlands between January 1, 2001 and December 31, 2021. Data collection involved clinical records and long-term assessments, including musculoskeletal function, growth disorders, urogenital function, sexual dysfunction, and sensory motor function. Results: A total of 11 patients were included, primarily females (73 %), with a median age at trauma of 12 years (P25-P75 7-14). Most patients had unstable Pelvic ring fractures resulting from high-energy trauma. Surgical interventions were common, with external fixation as the main initial surgical approach (n = 7, 70 %). Complications were observed in eight (73 %) patients. Musculoskeletal function revealed a range of issues in the lower extremity, daily activities, and mental and emotional domain. Long-term radiologic follow-up showed high rates of Pelvic malunion (n = 7, 64 %). Neurological function assessment showed motor and sensory function impairment in a subset of patients. Urogenital function was moderately affected, and sexual dysfunction was limited with most respondents reporting no issues. Conclusion: Paediatric Open Pelvic fractures are challenging injuries associated with significant short-term complications and long-term musculoskeletal and urogenital issues. Further research is needed to develop tailored treatment strategies and improve outcomes of these patients.

Refraining from closed reduction of displaced distal radius fractures in the emergency department-in short: the RECORDED trial.

BACKGROUND: With roughly 45,000 adult patients each year, distal radius fractures are one of the most common fractures in the emergency department. Approximately 60% of all these fractures are displaced and require surgery. The current guidelines advise to perform closed reduction of these fractures awaiting surgery, as it may lead to post-reduction pain relief and release tension of the surrounding neurovascular structures. Recent studies have shown that successful reduction does not warrant conservative treatment, while patients find it painful or even traumatizing. The aim of this study is to determine whether closed reduction can be safely abandoned in these patients. METHODS: In this multicenter randomized clinical trial, we will randomize between closed reduction followed by plaster casting and only plaster casting. Patients aged 18 to 75 years, presenting at the emergency department with a displaced distal radial fracture and requiring surgery according to the attending surgeon, are eligible for inclusion. Primary outcome is pain assessed with daily VAS scores from the visit to the emergency department until surgery. Secondary outcomes are function assessed by PRWHE, length of stay at the emergency department, length of surgery, return to work, patient satisfaction, and complications. A total of 134 patients will be included in this study with follow-up of 1 year. DISCUSSION: If our study shows that patients who did not receive closed reduction experience no significant drawbacks, we might be able to reorganize the initial care for distal radial fractures in the emergency department. If surgery is warranted, the patient can be sent home with a plaster cast to await the call for admission, decreasing the time spend in the emergency room drastically. TRIAL REGISTRATION: This trial was registered on January 27, 2023.

Identifying the severely injured benefitting from a specific level of trauma care in an inclusive network: A multicentre retrospective study.

INTRODUCTION: Defining major trauma (MT) with an Injury Severity Score (ISS) > 15 has limitations. This threshold is used for concentrating MT care in networks with multiple levels of trauma care. OBJECTIVE: This study aims to identify subgroups of severely injured patients benefiting on in-hospital mortality and non-fatal clinical outcome measures in an optimal level of trauma care. METHODS: A multicentre retrospective cohort study on data of the Dutch National Trauma Registry, region South West, from January 1, 2015 until December 31, 2019 was conducted. Patients ≥ 16 years admitted within 48 h after trauma transported with (H)EMS to a level I trauma centre (TC) or a non-level I trauma facility with a Maximum Abbreviated Injury Scale (MAIS) ≥ 3 were included. Patients with burns or patients of ≥ 65 years with an isolated hip fracture were excluded. Logistic regression models were used for comparing level I with non-level I. Subgroup analysis were done for MT patients (ISS > 15) and non-MT patients (ISS 9-14). RESULTS: A total of 7,493 records were included. In-hospital mortality of patients admitted to a non-level I trauma facility did not differ significantly from patients admitted to the level I TC (adjusted Odds Ratio (OR): 0.94; 95% confidence interval (CI) 0.68-1.30). This was also applicable for MT patients (OR: 1.06; 95% CI 0.73-1.53) and non-MT patients (OR: 1.30; 95% CI (0.56-3.03). Hospital and ICU LOS were significantly shorter for patients admitted to a non-level I trauma facilities, and patients admitted to a non-level I trauma facility were more likely to be discharged home. Findings were confirmed for MT and non-MT patients, per injured body region. CONCLUSION: All levels of trauma care performed equally on in-hospital mortality among severely injured patients (MAIS ≥ 3), although patients admitted to the level I TC were more severely injured. Subgroups of patients by body region or ISS, with a survival benefit or more favorable clinical outcome measures were not identified. Subgroups analysis on clinical outcome measures across different levels of trauma care in an inclusive trauma network is too simplistic if subgroups are based on injuries in specific body region or ISS only.

Trends in incidence, health care consumption, and costs for proximal femoral fractures in the Netherlands between 2000 and 2019: a nationwide study.

This study evaluated the incidence rates and societal burden of hip fractures in The Netherlands. Although incidence in the elderly population is decreasing and hospital stay is at an all-time low, the burden of medical costs and crude numbers of proximal femoral fractures are still rising in our aging population. PURPOSE: The aim of this nationwide study was to provide an overview of the incidence rate and economic burden of acute femoral neck and trochanteric fractures in The Netherlands. METHODS: Data of patients who sustained acute proximal femoral fractures in the period January 1, 2000, to December 31, 2019, were extracted from the National Medical Registration of the Dutch Hospital Database. The incidence rate, hospital length of stay (HLOS), health care and lost productivity costs, and years lived with disability (YLD) were calculated for age- and sex-specific groups. RESULTS: A total of 357,073 patients were included. The overall incidence rate increased by 22% over the 20-year study period from 16.4 to 27.1/100,000 person-years (py). The age-specific incidence rate in elderly > 65 years decreased by 16% (from 649.1 to 547.6/100,000 py). The incidence rate in men aged > 90 has surpassed the incidence rate in women. HLOS decreased in all age groups, hip fracture subtypes, and sexes from a mean of 18.5 to 7.2 days. The mean health care costs, over the 2015-2019 period, were lower for men (€17,723) than for women (€23,351) and increased with age to €26,639 in women aged > 80. Annual cumulative costs reached €425M, of which 73% was spent on women. CONCLUSION: The total incidence of hip fractures in The Netherlands has increased by 22%. Although incidence in the elderly population is decreasing and HLOS is at an all-time low, the burden of medical costs and crude numbers of proximal femoral fractures are still rising in our aging population.

Nonoperative versus operative management of frail institutionalized older patients with a proximal femoral fracture: a cost-utility analysis alongside a multicenter prospective cohort study.

Hip fractures are associated with significant healthcare costs. In frail institutionalized patients, the costs of nonoperative management are less than operative management with comparable short-term quality of life. Nonoperative management of hip fractures in patients at the end of life should be openly discussed with SDM. PURPOSE: The aim was to describe healthcare use with associated costs and to determine cost-utility of nonoperative management (NOM) versus operative management (OM) of frail institutionalized older patients with a proximal femoral fracture. METHODS: This study included institutionalized patients with a limited life expectancy aged ≥ 70 years who sustained a proximal femoral fracture in the Netherlands. Costs of hospital- and nursing home care were calculated. Quality adjusted life years (QALY) were calculated based on EuroQol-5D-5L utility scores at day 7, 14, and 30 and at 3 and 6 months. The incremental cost-effectiveness ratio (ICER) was calculated from a societal perspective. RESULTS: Of the 172 enrolled patients, 88 (51%) patients opted for NOM and 84 (49%) for OM. NOM was associated with lower healthcare costs at 6 months (NOM; €2425 (SD 1.030), OM; €9325 (SD 4242), p < 0.001). The main cost driver was hospital stay (NOM; €738 (SD 841) and OM; €3140 (SD 2636)). The ICER per QALY gained in the OM versus NOM was €76,912 and exceeded the threshold of €20,000 per QALY. The gained QALY were minimal in the OM group in patients who died within 14- and 30-day post-injury, but OM resulted in more than triple the costs. CONCLUSION: OM results in significant higher healthcare costs, mainly due to the length of hospital stay. For frail patients at the end of life, NOM of proximal femoral fractures should be openly discussed in SDM conversations due to the limited gain in QoL.

Comparing health status after major trauma across different levels of trauma care.

INTRODUCTION: Mortality due to trauma has reduced the past decades. Trauma network implementations have been an important contributor to this achievement. Besides mortality, patient reported outcome parameters should be included in evaluation of trauma care. While concentrating major trauma care, hospitals are designated with a certain level of trauma care following specific criteria. OBJECTIVE: Comparing health status of major trauma patients after two years across different levels of trauma care in trauma networks. METHODS: Multicentre observational study comprising a secondary longitudinal multilevel analysis on prospective cohorts from two neighbouring trauma regions in the Netherlands. INCLUSION CRITERIA: patient aged ≥ 18 with an ISS > 15 surviving their injuries at least one year after trauma. Health status was measured one and two years after trauma by EQ-5D-5 L, added with a sixth health dimension on cognition. Level I trauma centres were considered as reference in uni- and multivariate analysis. RESULTS: Respondents admitted to a level I trauma centre scored less favourable EQ-US and EQ-VAS in both years (0.81-0.81, 71-75) than respondents admitted to a level II (0.88-0.87, 78-85) or level III (0.89-0.88, 75-80) facility. Level II facilities scored significantly higher EQ-US and EQ-VAS in time for univariate analysis (ß 0.095, 95% CI 0.038-0.153, p = 0.001, and ß 7.887, 95% CI 3.035-12.740, p = 0.002), not in multivariate analysis (ß 0.052, 95% CI -0.010-0.115, p = 0.102, and ß 3.714, 95% CI -1.893-9.321, p = 0.193). Fewer limitations in mobility (OR 0.344, 95% CI 0.156-0.760), self-care (OR 0.219, 95% CI 0.077-0.618), and pain and discomfort (OR 0.421, 95% CI 0.214-0.831) remained significant for level II facilities in multivariate analysis, whereas significant differences with level III facilities disappeared. CONCLUSION: Major trauma patients admitted to level I trauma centres reported a less favourable general health status and more limitations compared to level II and III facilities scoring populations norms one to two years after trauma. Differences on general health status and limitations in specific health domains disappeared in adjusted analysis. Well-coordinated trauma networks offer homogeneous results for all major trauma patients when they are distributed in different centres according to their need of care.

Prognosis and institutionalization of frail community-dwelling older patients following a proximal femoral fracture: a multicenter retrospective cohort study.

Hip fractures are a serious public health issue with major consequences, especially for frail community dwellers. This study found a poor prognosis at 6 months post-trauma with regard to life expectancy and rehabilitation to pre-fracture independency levels. It should be realized that recovery to pre-trauma functioning is not a certainty for frail community-dwelling patients. INTRODUCTION: Proximal femoral fractures are a serious public health issue in the older patient. Although a significant rise in frail community-dwelling elderly is expected because of progressive aging, a clear overview of the outcomes in these patients sustaining a proximal femoral fracture is lacking. This study assessed the prognosis of frail community-dwelling patients who sustained a proximal femoral fracture. METHODS: A multicenter retrospective cohort study was performed on frail community-dwelling patients with a proximal femoral fracture who aged over 70 years. Patients were considered frail if they were classified as American Society of Anesthesiologists score ≥ 4 and/or a BMI < 18.5 kg/m2 and/or Functional Ambulation Category ≤ 2 pre-trauma. The primary outcome was 6-month mortality. Secondary outcomes were adverse events, health care consumption, rate of institutionalization, and functional recovery. RESULTS: A total of 140 out of 2045 patients matched the inclusion criteria with a median age of 85 (P25-P75 80-89) years. The 6-month mortality was 58 out of 140 patients (41%). A total of 102 (73%) patients experienced adverse events. At 6 months post-trauma, 29 out of 120 (24%) were readmitted to the hospital. Out of the 82 surviving patients after 6 months, 41 (50%) were unable the return to their home, and only 32 (39%) were able to achieve outdoor ambulation. CONCLUSION: Frail community-dwelling older patients with a proximal femoral fracture have a high risk of death, adverse events, and institutionalization and often do not reobtain their pre-trauma level of independence. Foremost, the results can be used for realistic expectation management.

Measuring intracompartmental pressures for the chronic exertional compartment syndrome: Challenging commercially available devices and their respective accuracy.

The aim of this study was to compare commercially available manometers and needles used for intracompartmental pressure measurements for accuracy. An experimental compartment simulation model was developed in order to compare four different terminal devices (Compass manometer, Stryker device, Meritrans transducer, and arterial line) and 22 types of needles. First, all possible device/needle combinations were introduced in rubber ports at the bottom of a water column. The water column was gradually drained three times for each device/needle combination and pressures were recorded by two researchers. This procedure was repeated after placement of a sample of homogenous porcine gluteal muscle tissue. When measuring the fluid column only, all Intraclass Correlation Coefficients were found to be ≥0.980, indicating good resemblance to the reference pressure. After addition of the muscle tissue to the experimental set up, accuracy of the Stryker device and arterial line remained the same. The accuracy of the Compass manometer and Meritrans transducer became less. Excellent reliability was found for 7 out of 22 needles when combined with the Stryker device and for 2 out of 22 needles when combined with the arterial line. The four terminal devices tested were all accurate when measuring pressure in a water column, whereas only the Stryker device and arterial line accurately represented the water column pressure in a porcine gluteal muscle model. Future research will have to verify whether these results can be repeated in human cadaver models and in vivo.

Does circumferential casting prevent fracture redisplacement in reduced distal radius fractures? A retrospective multicentre study.

BACKGROUND: This study evaluates whether a circumferential cast compared to a plaster splint leads to less fracture redisplacement in reduced extra-articular distal radius fractures (DRFs). METHODS: This retrospective multicentre study was performed in four hospitals (two teaching hospitals and two academic hospitals). Adult patients with a displaced extra-articular DRF, treated with closed reduction, were included. Patients were included from a 5-year period (January 2012-January 2017). According to the hospital protocol, fractures were immobilized with a below elbow circumferential cast (CC) or a plaster splint (PS). The primary outcome concerned the difference in the occurrence of fracture redisplacement at one-week follow-up. RESULTS: A total of 500 patients were included in this study (PS n = 184, CC n = 316). At one-week follow-up, fracture redisplacement occurred in 52 patients (17%) treated with a CC compared to 53 patients (29%) treated with a PS. This difference was statistically significant (p = 0.001). CONCLUSION: This study suggests that treatment of reduced DRFs with a circumferential cast might cause less fracture redisplacement at 1-week follow-up compared to treatment with a plaster splint.

Use of antibiotic coated intramedullary nails in open tibia fractures: A European medical resource use and cost-effectiveness analysis.

PURPOSE: In patients with open tibial fractures, bone and wound infections are associated with an increased hospital length of stay and higher costs. The infection risk increases with the use of implants. Innovations to reduce this risk include antibiotic-coated implants. This study models whether the use of a gentamicin-coated intramedullary tibial nail is cost-effective for trauma centers managing patients with a high risk of infection. EFFICACY: Absolute infection risk and relative risk reduction, by fracture grade, for antibiotic-coated nails compared to standard nails for patients with open tibial fractures were estimated based on the results of a meta-analysis, which assessed the additional benefit of locally-administered prophylactic antibiotics in open tibia fractures treated with implants. The observed efficacy of antibiotic-coated nails in reducing infections was applied in an economic model. METHODS: The model compared infection rates, inpatient days, theatre usage and costs in high risk patients, with a Gustilo-Anderson (GA) grade III open fracture, for two patient cohorts from a trauma center perspective, with a 1-year time horizon. In one cohort all GAIII patients received a gentamicin-coated nail whilst GAI and GAII patients received a standard nail. All patients in the comparator cohort received a standard nail. Four European trauma centers provided patient-level data (n=193) on inpatient days, procedures and related costs for patients with and without infections. RESULTS: Using the gentamicin-coated nail in patients at high risk of infection (GAIII) was associated with 75% lower rate of infection and cost savings (€477 - €3.263) for all included centers; the higher cost of the implant was offset by savings from fewer infections, inpatient days (-26%) and re-operations (-10%). This result was confirmed by extensive sensitivity analyses. CONCLUSIONS: Analyses demonstrated that infection rates and total costs for in-hospital treatment could be potentially reduced by 75% and up to 15% respectively, by using a gentamicin-coated nail in patients at high risk of infection. Fewer infections, reduced inpatient days and re-operations may be potentially associated with use of antibiotic-coated implants. Results are sensitive to the underlying infection risk, with greatest efficacy and cost-savings when the coated implant is used in high risk patients.

Trauma mechanism and patient reported outcome in tibial plateau fractures with posterior involvement.

INTRODUCTION: Posterior tibial plateau fractures (PTPF) have a high impact on functional outcome and the optimal treatment strategy is not well established. The goal of this study was to assess the relationship between trauma mechanism, fracture morphology and functional outcome in a large multicenter cohort and define possible strategies to improve the outcome. METHODS: An international retrospective cohort study was conducted in five level-1 trauma centers. All consecutive operatively treated PTPF were evaluated. Preoperative imaging was reviewed to determine the trauma mechanism. Patient reported outcome was scored using the Knee injury and Osteoarthritis Outcome Score (KOOS). RESULTS: A total of 145 tibial plateau fractures with posterior involvement were selected with a median follow-up of 32.2 months (IQR 24.1-43.2). Nine patients (6%) sustained an isolated posterior fracture. Seventy-two patients (49%) sustained a two-column fracture and three-column fractures were diagnosed in 64 (44%) patients. Varus trauma was associated with poorer outcome on the 'symptoms' (p = 0.004) and 'pain' subscales (p = 0.039). Delayed-staged surgery was associated with worse outcome scores for all subscales except 'pain'. In total, 27 patients (18%) were treated with posterior plate osteosynthesis without any significant difference in outcome. CONCLUSIONS: Fracture morphology, varus trauma mechanism and delayed-staged surgery (i.e. extensive soft-tissue injury) were identified as important prognostic factors on postoperative outcome in PTPF. In order to assess possible improvement of outcome, future studies with routine preoperative MRI to assess associated ligamentous injury in tibial plateau fractures (especially for varus trauma) are needed.

Management of critical-sized bone defects in the treatment of fracture-related infection: a systematic review and pooled analysis.

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.

Treatment of dorsally dislocated distal radius fractures with individualized 3D printed bracing: an exploratory study.

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. TRIAL REGISTRATION: Name of the registry: ClinicalTrials.Gov Trial registration number: NCT03848702 Date of registration: 02/21/2019, retrospectively registered.

Functional Outcomes after Corrective Osteotomy of Symptomatic Distal Radius Malunions in Children.

Background Closed reduction and cast immobilization of displaced distal radius fractures carries the risk of secondary displacement, which could result in a symptomatic malunion. In patients with a symptomatic malunion, a corrective osteotomy can be performed to improve pain and functional impairment of the wrist joint. Objective The aim of this study was to assess the functional outcomes of children who underwent a corrective osteotomy due to a symptomatic malunion of the distal radius. Methods Between 2009 and 2016, all consecutive corrective osteotomies of the distal radius of patients younger than 18 years were reviewed. The primary outcome was functional outcome assessed with the ABILHAND-Kids score. Secondary outcomes were QuickDASH (Quick Disabilities of Arm, Shoulder, and Hand) score, range of motion, complications, and radiological outcomes. Results A total of 13 patients with a median age of 13 years (interquartile range [IQR]: 12.5-16) were included. The median time to follow-up was 31 months (IQR: 26-51). The median ABILHAND-Kids score was 42 (range: 37-42), and the median QuickDASH was 0 (range: 0-39). Range of motion did not differ significantly between the injured and the uninjured sides for all parameters. One patient had a nonunion requiring additional operative treatment. The postoperative radiological parameters showed an improvement of radial inclination, radial height, ulnar variance, dorsal tilt, and dorsal tilt. Conclusion Corrective osteotomy for children is an effective method for treating symptomatic malunions of the distal radius. Level of Evidence This is a Level IV study.

Rib fractures after blunt thoracic trauma in patients with normal versus diminished bone mineral density: a retrospective cohort study.

This study aimed to evaluate rib fracture rate as well as rib fracture characteristics after thoracic trauma in patients with normal versus diminished bone mineral density (BMD). A retrospective cohort study of persons aged 50 years or older presenting to the Emergency Department after sustaining blunt thoracic trauma between July 1, 2014, and December 31, 2017, was performed. Patient and trauma characteristics and DXA scan results were collected. Rib fracture rate and characteristics were evaluated on a radiograph and/or CT scan of the thorax. In total, 119 patients were included for analysis. Fifty-eight of them (49%) had a diminished BMD. In the remaining 61, the BMD was normal. The diminished BMD group experienced rib fractures more often than the normal BMD group (n = 43 (74%) versus n = 31 (51%); p = 0.014). Patients with diminished BMD suffered low-energy trauma more frequently than the normal BMD group (21 (36%) versus 11 patients (15%), respectively (p = 0.011)). Rib fracture characteristics such as the median number of rib fractures, concomitant intrathoracic injury rate, and rib fracture type distribution were not different between the groups. The rate of rib fractures after blunt thoracic trauma was significantly higher in patients with diminished BMD than in patients with a normal BMD. Differences in number and location of rib fractures between groups could not be proven. When assessing patients aged 50 years or older presenting to the hospital after substantial blunt thoracic trauma, the presence of diminished BMD should be taken into account and the presence of rib fractures should be investigated with appropriate diagnostic procedures. Diminished bone mineral density (i.e., osteopenia or osteoporosis) is associated with increased fracture risk. This study evaluated if diminished BMD increases the rib fracture risk. Patients with diminished BMD have a higher risk of sustaining rib fractures after substantial blunt thoracic trauma, which implicates a lower threshold for CT imaging of the chest.

Open reduction and internal fixation versus closed reduction and percutaneous fixation in the treatment of Bennett fractures: A systematic review.

PURPOSE: Open reduction and internal fixation (ORIF) of Bennett fractures is increasingly preferred over closed reduction and percutaneous fixation (CRIF) in an attempt to prevent the development of post-traumatic arthrosis. The aim of this systematic review was to determine whether the preference for ORIF is justified based on the available literature regarding functional outcome and complications after surgery. METHODS: A systematic review was performed in Medline, Embase, Cochrane CENTRAL, Web of science, and Google scholar. Duplicates were removed and title and abstract were screened after which full text articles were analysed. The reference lists of selected articles were screened for additional relevant studies. Study characteristics were recorded and methodological qualities were assessed after which data was extracted from the included articles. The Eaton-Littler score for post-traumatic arthrosis (primary outcome) on follow-up X-rays was used as primary outcome. Secondary outcomes were Grip strength, Pinch strength, persistent pain, fixation failure, functional impairment, infection and surgery time. RESULTS: Ten studies were included; three retrospective comparative studies and seven retrospective case series. Of the 215 patients in these studies, 138 had been treated using an open technique and 77 by a closed percutaneous technique. The pooled rate of post-traumatic arthrosis was 57.5% (26.6-85.5) in the ORIF group versus 26.1% (3.9-59.0) in the CRIF group. Mean surgical operation time was 71.9 min for ORIF and 30.2 min for percutaneous patients. Fixation failure was significantly more often seen in the ORIF patients, 8.2% (0.7-22.8) vs. 2.9% (0.8-9.1), Risk Ratio 1.132 (0.01-176.745); p = 0.048. Infection was only seen in 5 CRIF patients. Persistent pain was seen in 32.9% (0.6-83.1) in ORIF patients versus 22.3% (8.1-41.1) in the CRIF patients. The pooled means Grip strength was 48.3 kg (95% CI; 39.7-56.9) versus 43.4 kg (95% CI; 22.9-63.8) for ORIF and CRPF, respectively. Functional impairment was similar between the two groups, 1.4% (0.1-4.4) vs 1.8% (0.1-5.7) respectively. CONCLUSION: The analysed data do not confirm ORIF to prevent post-traumatic arthrosis, secondly more fixation failure and pain was seen in the ORIF group. The pooled data show percutaneous fixation to be preferable over ORIF in the surgical treatment of Bennett fractures.

Is there an association between female gender and outcome in severe trauma? A multi-center analysis in the Netherlands.

INTRODUCTION: Little evidence suggest that female gender is associated with a lower risk of mortality in severely injured patients, especially in premenopausal women. Previous clinical studies have shown contradictory results regarding protective effects of gender on outcome after severe trauma. The objective of this study was to determine the association between gender and outcome (mortality and Intensive Care Unit (ICU) admission) among severely injured patients in the Netherlands. METHODS: A retrospective multicentre study was performed including all polytrauma patients (Injury Severity Score (ISS) ≥16) admitted to the ED of three level 1 trauma centres, between January 1st, 2006 and December 31st, 2014. Data on age, gender, mechanism of injury, ISS, Abbreviated Injury Scale (AIS), prehospital intubation, Revised Trauma Score (RTS), systolic blood pressure (SBP) and Glasgow Coma Scale (GCS) upon admission at the Emergency Department was collected from three Regional Trauma Registries. To determine whether gender was an independent predictor of mortality and ICU admission, logistic regression analysis was performed. RESULTS: Among 6865 trauma patients, male patients had a significantly higher ISS compared to female patients (26.3 ± 10.2 vs 25.3 ± 9.7, P = < 0.0001). Blunt trauma was significantly more common in the female group (95.2% vs 92.3%, P = < 0.0001). Males aged 16- to 44-years had a significant higher in-hospital mortality rate (10.4% vs 13.4%, P = 0.046). ICU admission rate was significantly lower in females (49.3% vs 54.5%, P = < 0.0001). In the overall group, logistic regression did not show gender as an independent predictor for in-hospital mortality (OR 1.020 (95% CI 0.865-1.204), P = 0.811) or mortality within 24 h (OR 1.049 (95% CI 0.829-1.327), P = 0.693). However, male gender was associated with an increased likelihood for ICU admission in the overall group (OR 1.205 (95% CI 1.046-1.388), P = 0.010). CONCLUSION: The current study shows that in this population of severely injured patients, female sex is associated with a lower in-hospital mortality rate among those aged 16- to 44-years. Furthermore, female sex is independently associated with an overall decreased likelihood for ICU admission. More research is needed to examine the physiologic background of this protective effect of female sex in severe trauma.

Bennett's fracture: Comparative study between open and closed surgical techniques.

The aim of this study was to assess long-term outcomes of surgically treated Bennett fractures, while comparing open reduction and internal fixation (ORIF) with closed reduction and percutaneous fixation (CRPF). Patients treated between 1994 and 2010 were assessed retrospectively during an outpatient visit using a validated questionnaire (i.e. DASH, pain assessed through VAS), sensory testing, grip- and pinch-strength and radiographic analysis for post-traumatic arthritis. Fifty patients were included. Mean follow-up was 10 years. Mean age at trauma was 34 years. ORIF was used in 35 patients. CRPF was used in 15 patients. No differences in grip- and pinch-strength were found. Re-operations were needed in five ORIF-treated patients. Higher Pain Scores (VAS) were seen in the ORIF-treated patients. No correlation was found between surgical technique and functional outcomes. A persistent step-off or gap larger than 2 mm after surgical fixation was significantly correlated with post-traumatic arthritis at 10 years' follow-up. The need to perform ORIF for anatomical reduction seems to be less important in preventing post-traumatic arthritis as a persistent step-off or gap of more than 2 mm was found to be significantly correlated with the development of post-traumatic arthritis. Secondly, both techniques lead to good functional outcomes, although persistent pain was seen in the ORIF-treated patients. Bennett fractures can therefore be safely treated with CRPF when the persistent step-off and gap after fixation do not exceed 2 mm. LEVEL OF EVIDENCE: Therapeutic study, Level III.

Insights into treatment and outcome of fracture-related infection: a systematic literature review.

INTRODUCTION: Standardized guidelines for treatment of fracture-related infection (FRI) are lacking. Worldwide many treatment protocols are used with variable success rates. Awareness on the need of standardized, evidence-based guidelines has increased in recent years. This systematic literature review gives an overview of available diagnostic criteria, classifications, treatment protocols, and related outcome measurements for surgically treated FRI patients. METHODS: A comprehensive search was performed in all scientific literature since 1990. Studies in English that described surgical patient series for treatment of FRI were included. Data were collected on diagnostic criteria for FRI, classifications used, surgical treatments, follow-up protocols, and overall outcome. A systematic review was performed according to the PRISMA statement. Proportions and weighted means were calculated. RESULTS: The search yielded 2051 studies. Ninety-three studies were suitable for inclusion, describing 3701 patients (3711 fractures) with complex FRI. The population consisted predominantly of male patients (77%), with the tibia being the most commonly affected bone (64%), and a mean of three previous operations per patient. Forty-three (46%) studies described FRI at one specific location. Only one study (1%) used a standardized definition for infection. A total of nine different classifications were used to guide treatment protocols, of which Cierny and Mader was used most often (36%). Eighteen (19%) studies used a one-stage, 50 (54%) a two-stage, and seven (8%) a three-stage surgical treatment protocol. Ten studies (11%) used mixed protocols. Antibiotic protocols varied widely between studies. A multidisciplinary approach was mentioned in only 12 (13%) studies. CONCLUSIONS: This extensive literature review shows a lack of standardized guidelines with respect to diagnosis and treatment of FRI, which mimics the situation for prosthetic joint infection identified many years ago. Internationally accepted guidelines are urgently required to improve the quality of care for patients suffering from this significant complication.
