Time is of the essence when treating necrotizing soft tissue infections: a systematic review and meta-analysis

Background

Although the phrase “time is fascia” is well acknowledged in the case of necrotizing soft tissue infections (NSTIs), solid evidence is lacking. The aim of this study is to review the current literature concerning the timing of surgery in relation to mortality and amputation in patients with NSTIs.

Methods

A systematic search in PubMed/MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and the Cochrane Controlled Register of Trials (CENTRAL) was performed. The primary outcomes were mortality and amputation. These outcomes were related to the following time-related variables: (1) time from onset symptoms to presentation; (2) time from onset symptoms to surgery; (3) time from presentation to surgery; (4) duration of the initial surgical procedure. For the meta-analysis, the effects were estimated using random-effects meta-analysis models.

Result

A total of 109 studies, with combined 6051 NSTI patients, were included. Of these 6051 NSTI patients, 1277 patients died (21.1%). A total of 33 studies, with combined 2123 NSTI patients, were included for quantitative analysis. Mortality was significantly lower for patients with surgery within 6 h after presentation compared to when treatment was delayed more than 6 h (OR 0.43; 95% CI 0.26–0.70; 10 studies included). Surgical treatment within 6 h resulted in a 19% mortality rate compared to 32% when surgical treatment was delayed over 6 h. Also, surgery within 12 h reduced the mortality compared to surgery after 12 h from presentation (OR 0.41; 95% CI 0.27–0.61; 16 studies included). Patient delay (time from onset of symptoms to presentation or surgery) did not significantly affect the mortality in this study. None of the time-related variables assessed significantly reduced the amputation rate. Three studies reported on the duration of the first surgery. They reported a mean operating time of 78, 81, and 102 min with associated mortality rates of 4, 11.4, and 60%, respectively.

Conclusion

Average mortality rates reported remained constant (around 20%) over the past 20 years. Early surgical debridement lowers the mortality rate for NSTI with almost 50%. Thus, a sense of urgency is essential in the treatment of NSTI.

Global changes in mortality rates in polytrauma patients admitted to the ICU-a systematic review

Background

Many factors of trauma care have changed in the last decades. This review investigated the effect of these changes on global all-cause and cause-specific mortality in polytrauma patients admitted to the intensive care unit (ICU). Moreover, changes in trauma mechanism over time and differences between continents were analyzed.

Main body

A systematic review of literature on all-cause mortality in polytrauma patients admitted to ICU was conducted. All-cause and cause-specific mortality rates were extracted as well as trauma mechanism of each patient. Poisson regression analysis was used to model time trends in all-cause and cause-specific mortality.

Thirty studies, which reported mortality rates for 82,272 patients, were included and showed a decrease of 1.8% (95% CI 1.6–2.0%) in all-cause mortality per year since 1966. The relative contribution of brain injury-related death has increased over the years, whereas the relative contribution of death due to multiple organ dysfunction syndrome (MODS), acute respiratory distress syndrome, and sepsis decreased. MODS was the most common cause of death in North America, and brain-related death was the most common in Asia, South America, and Europe. Penetrating trauma was most often reported in North America and Asia.

Conclusions

All-cause mortality in polytrauma patients admitted to the ICU has decreased over the last decades. A shift from MODS to brain-related death was observed. Geographical differences in cause-specific mortality were present, which may provide region-specific learning possibilities resulting in improvement of global trauma care.

Surgical Versus Nonsurgical Treatment for Midshaft Clavicle Fractures in Patients Aged 16 Years and Older: A Systematic Review, Meta-analysis, and Comparison of Randomized Controlled Trials and Observational Studies

BACKGROUND

There is no consensus on the choice of treatment of midshaft clavicle fractures (MCFs).

PURPOSE

The aims of this systematic review and meta-analysis were (1) to compare fracture healing disorders and functional outcomes of surgical versus nonsurgical treatment of MCFs and (2) to compare effect estimates obtained from randomized controlled trials (RCTs) and observational studies.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

The PubMed/MEDLINE, Embase, CENTRAL, and CINAHL databases were searched for both RCTs and observational studies. Using the MINORS instrument, all included studies were assessed on their methodological quality. The primary outcome was a nonunion. Effects of surgical versus nonsurgical treatment were estimated using random-effects meta-analysis models.

RESULTS

A total of 20 studies were included, of which 8 were RCTs and 12 were observational studies including 1760 patients. Results were similar across the different study designs. A meta-analysis of 19 studies revealed that nonunions were significantly less common after surgical treatment than after nonsurgical treatment (odds ratio [OR], 0.18 [95% CI, 0.10-0.33]). The risk of malunions did not differ between surgical and nonsurgical treatment (OR, 0.38 [95% CI, 0.12-1.19]). Both the long-term Disabilities of the Arm, Shoulder and Hand (DASH) and Constant-Murley scores favored surgical treatment (DASH: mean difference [MD], -2.04 [95% CI, -3.56 to -0.52]; Constant-Murley: MD, 3.23 [95% CI, 1.52 to 4.95]). No differences were observed regarding revision surgery (OR, 0.85 [95% CI, 0.42-1.73]). Including only high-quality studies, both the number of malunions and days to return to work show significant differences in favor of surgical treatment (malunions: OR, 0.26 [95% CI, 0.07 to 0.92]; return to work: MD, -8.64 [95% CI, -16.22 to -1.05]).

CONCLUSION

This meta-analysis of high-quality studies showed that surgical treatment of MCFs results in fewer nonunions, fewer malunions, and an accelerated return to work compared with nonsurgical treatment. A meta-analysis of surgical treatments need not be restricted to randomized trials, provided that the included observational studies are of high quality.

Accuracy of Prehospital Triage in Selecting Severely Injured Trauma Patients

Importance

A major component of trauma care is adequate prehospital triage. To optimize the prehospital triage system, it is essential to gain insight in the quality of prehospital triage of the entire trauma system.

Objective

To prospectively evaluate the quality of the field triage system to identify severely injured adult trauma patients.

Design, Setting, and Participants

Prehospital and hospital data of all adult trauma patients during 2012 to 2014 transported with the highest priority by emergency medical services professionals to 10 hospitals in Central Netherlands were prospectively collected. Prehospital data collected by the emergency medical services professionals were matched to hospital data collected in the trauma registry. An Injury Severity Score of 16 or more was used to determine severe injury.

Main Outcomes and Measures

The quality and diagnostic accuracy of the field triage protocol and compliance of emergency medical services professionals to the protocol.

Results

A total of 4950 trauma patients were evaluated of which 436 (8.8%) patients were severely injured. The undertriage rate based on actual destination facility was 21.6% (95% CI, 18.0-25.7) with an overtriage rate of 30.6% (95% CI, 29.3-32.0). Analysis of the protocol itself, regardless of destination facility, resulted in an undertriage of 63.8% (95% CI, 59.2-68.1) and overtriage of 7.4% (95% CI, 6.7-8.2). The compliance to the field triage trauma protocol was 73% for patients with a level 1 indication.

Conclusions and Relevance

More than 20% of the patients with severe injuries were not transported to a level I trauma center. These patients are at risk for preventable morbidity and mortality. This finding indicates the need for improvement of the prehospital triage protocol.

Comparison of analgesic interventions for traumatic rib fractures: a systematic review and meta-analysis

Purpose

Many studies report on outcomes of analgesic therapy for (suspected) traumatic rib fractures. However, the literature is inconclusive and diverse regarding the management of pain and its effect on pain relief and associated complications. This systematic review and meta-analysis summarizes and compares reduction of pain for the different treatment modalities and as secondary outcome mortality during hospitalization, length of mechanical ventilation, length of hospital stay, length of intensive care unit stay (ICU) and complications such as respiratory, cardiovascular, and/or analgesia-related complications, for four different types of analgesic therapy: epidural analgesia, intravenous analgesia, paravertebral blocks and intercostal blocks.

Methods

PubMed, EMBASE and CENTRAL databases were searched to identify comparative studies investigating epidural, intravenous, paravertebral and intercostal interventions for traumatic rib fractures, without restriction for study type. The search strategy included keywords and MeSH or Emtree terms relating blunt chest trauma (including rib fractures), analgesic interventions, pain management and complications.

Results

A total of 19 papers met our inclusion criteria and were finally included in this systematic review. Significant differences were found in favor of epidural analgesia for the reduction of pain. No significant differences were observed between epidural analgesia, intravenous analgesia, paravertebral blocks and intercostal blocks, for the secondary outcomes.

Conclusions

Results of this study show that epidural analgesia provides better pain relief than the other modalities. No differences were observed for secondary endpoints like length of ICU stay, length of mechanical ventilation or pulmonary complications. However, the quality of the available evidence is low, and therefore, preclude strong recommendations.

Clavicle fractures in adults; current concepts

BACKGROUND

For decades, clavicle fractures have been treated conservatively. In the last 20 years, however, non-union rates after conservative treatment appear higher than previously reported and more evidence regarding operative treatment has become available. This has led to a paradigm shift towards an increase in operative treatment. The aim of this review is to present the current concepts and available evidence regarding clavicle fracture treatment.

METHODS

Conservative and operative treatment options together with their indications for medial, shaft and lateral clavicle fractures are discussed. For all three anatomical locations, a treatment algorithm is proposed.

CONCLUSION

In general, non-displaced fractures are treated conservatively. Operative treatment has to be discussed with patients with displaced clavicle fractures, especially in the young and active patient.

Brodie's Abscess: A Systematic Review of Reported Cases

Introduction: Brodie's abscess is a form of osteomyelitis. Since its first appearance in the medical literature in 1832, numerous cases have been described. The aim of this article is to provide the first comprehensive overview of published cases of Brodie's abscess, and to describe diagnostic methods, therapeutic consequences and outcomes.

Methods: According to PRISMA guidelines a systematic review of the literature was performed. All published data in English or Dutch were considered for inclusion with no limitations on publication date. Data was extracted on demography, duration of symptoms, signs of inflammation, diagnostic imaging, causative agent, treatment and follow-up.

Results: A total of 70 articles were included, reporting on a total of 407 patients, mostly young (median age 17) males (male:female ratio 2.1:1). The median duration of symptoms before diagnosis was 12 weeks (SD 26). Mostly consisting of pain (98%) and/or swelling (53%). 84% of all patients were afebrile, and less than 50% had elevated serum inflammation markers. Diagnosis was made with a combination of imaging modalities: plain X-ray in 96%, MRI (16%) and CT-scan (8%). Treatment consisted of surgery in 94% of the cases, in conjunction with long term antibiotics in 77%. Staphylococcus aureus was the pathogen most often found in the culture (67,3%). Outcome was generally reported as favorable. Recurrence was reported in 15,6% of the cases requiring further intervention. Two cases developed permanent disability.

Conclusion: Brodie's abscess has an insidious onset as systemic inflammatory signs and symptoms were often not found. Treatment consisted mostly of surgery followed by antibiotics (77%) or only surgery (17%) and outcomes were generally reported as favourable.

Getting it right first time: The importance of a structured tissue sampling protocol for diagnosing fracture-related infections

INTRODUCTION

Fracture-related infection (FRI) is an important complication following surgical fracture management. Key to successful treatment is an accurate diagnosis. To this end, microbiological identification remains the gold standard. Although a structured approach towards sampling specimens for microbiology seems logical, there is no consensus on a culture protocol for FRI. The aim of this study is to evaluate the effect of a structured microbiology sampling protocol for fracture-related infections compared to ad-hoc culture sampling.

METHODS

We conducted a pre-/post-implementation cohort study that compared the effects of implementation of a structured FRI sampling protocol. The protocol included strict criteria for sampling and interpretation of tissue cultures for microbiology. All intraoperative samples from suspected or confirmed FRI were compared for culture results. Adherence to the protocol was described for the post-implementation cohort.

RESULTS

In total 101 patients were included, 49 pre-implementation and 52 post-implementation. From these patients 175 intraoperative culture sets were obtained, 96 and 79 pre- and post-implementation respectively. Cultures from the pre-implementation cohort showed significantly more antibiotic use during culture sampling (P =  0.002). The post-implementation cohort showed a tendency more positive culture sets (69% vs. 63%), with a significant difference in open wounds (86% vs. 67%, P =  0.034). In all post-implementation culture sets causative pathogens were cultured more than once per set, in contrast to pre-implementation. Despite stricter tissue sampling and culture interpretation criteria, the number of polymicrobial infections was similar in both cohorts, approximately 29% of all culture sets and 44% of all positive culture sets. Significantly more polymicrobial cultures were found in early infections in the post-implementation cohort (P =  0.048). This indicates a better yield in the new protocol.

CONCLUSION

A standardised protocol for intraoperative sampling for bacterial identification in FRI is superior than an ad-hoc approach. It has a positive effect on both surgeon and microbiologist by increasing awareness about the problem at hand. This resulted in more microbiologically confirmed infections and more certainty when identifying causative pathogens.

Systematic review of complications after intramedullary fixation for displaced midshaft clavicle fractures

BACKGROUND

The number of displaced midshaft clavicle fractures treated surgically is increasing, and open reduction and intramedullary fixation is an emerging surgical treatment option. The study quality and scientific levels of published evidence in which possible complications of this treatment are presented vary greatly.

METHODS

We performed systematic computer-based searches of EMBASE and PubMed/MEDLINE. Studies included for review reported complications after intramedullary fixation alone or in comparison to either treatment with plate fixation and/or nonoperative treatment. The Level of Evidence rating and Quality Assessment Tool were used to assess the methodological quality of the studies. Included studies were ranked according to their levels of evidence.

RESULTS

Six articles were eligible for inclusion and final quality assessment; 3 studies were graded the highest level of evidence. Major complications like bone-healing problems and deep infections requiring implant removal were reported at a rate no higher than 7%. Reported rates for minor complications, such as wound infection and implant irritation that could be resolved without further surgery, were as high as 31%.

CONCLUSION

The noted rates for major complications requiring additional surgery were low, but implant-related problems that require additional surgery might present with high prevalence. Owing to routine implant removal, treatment with intramedullary fixation often requires an additional surgical procedure.

Surgical fixation of midshaft clavicle fractures: A systematic review of biomechanical studies

PURPOSE

Surgical treatment of displaced midshaft clavicle fractures requires a decision between plate fixation and intramedullary (IM) fixation. Numerous studies report on the biomechanical properties of various repair constructs. The goal of this systematic review was to provide an overview of studies describing the biomechanical properties of the most commonly used surgical fixations of midshaft clavicle fractures. Additionally, we aimed to translate these biomechanical results into clinically relevant conclusions.

METHODS

A computer-aided search of the EMBASE and PudMed/MEDLINE databases was conducted. Studies included for review compared biomechanical properties of plate fixation with IM fixation and superiorly positioned plates with anteroinferiorly positioned plates for midshaft clavicle fractures.

RESULTS

Fifteen studies were eligible for inclusion. Plate fixation seemed to form a more robust construct than IM fixation in terms of stiffness and failure loading. The remaining clavicle was stronger after removal of the IM device than after removal of the plate. Superior plating of transverse fractures generally seemed to provide greater stiffness and strength during bending loads than anteroinferior plating did. The absence of cortical alignment in wedge and comminuted fractures directly influenced the fixation stability for both IM fixation and plate fixation, regardless of location.

CONCLUSION

Each type of fracture fixation has biomechanical advantages and disadvantages. However, exact thresholds of stiffness for inducing healing and failure strength to withstand refractures are unknown. The clinical relevance of the biomechanical studies may be arguable. Since none of the studies investigate the effect of tissue adaptation over time they should be interpreted with caution.

Quality of reporting of systematic reviews and meta-analyses in emergency medicine based on the PRISMA statement

BACKGROUND

Emergency department utilization has increased tremendously over the past years, which is accompanied by an increased necessity for emergency medicine research to support clinical practice. Important sources of evidence are systematic reviews (SRs) and meta-analyses (MAs), but these can only be informative provided their quality is sufficiently high, which can only be assessed if reporting is adequate. The purpose of this study was to assess the quality of reporting of SRs and MAs in emergency medicine using the PRISMA statement.

METHODS

The top five emergency medicine related journals were selected using the 5-year impact factor of the ISI Web of Knowledge of 2015. All SRs and MAs published in these journals between 2015 and 2016 were extracted and assessed independently by two reviewers on compliance with each item of the PRISMA statement.

RESULTS

The included reviews (n = 112) reported a mean of 18 ± 4 items of the PRISMA statement adequately. Reviews mentioning PRISMA adherence did not show better reporting than review without mention of adherence (mean 18.6 (SE 0.4) vs. mean 17.8 (SE 0.5); p = 0.214). Reviews published in journals recommending or requiring adherence to a reporting guideline showed better quality of reporting than journals without such instructions (mean 19.2 (SE 0.4) vs. mean 17.2 (SE 0.5); p = 0.001).

CONCLUSION

There is room for improvement of the quality of reporting of SRs and MAs within the emergency medicine literature. Therefore, authors should use a reporting guideline such as the PRISMA statement. Active journal implementation, by requiring PRISMA endorsement, enhances quality of reporting.

The evolution of trauma care in the Netherlands over 20 years

Introduction

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).

Materials and Methods

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.

Results

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.

Conclusion

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

Intramedullary Fixation Versus Plate Fixation of Distal Fibular Fractures: A Systematic Review and Meta-Analysis of Randomized Controlled Trials and Observational Studies

Intramedullary fixation (IMF) has been described as a minimally invasive alternative to open reduction and internal fixation for operative treatment of distal fibular fractures in case of compromised soft tissue or severe comorbidities. The objective was to compare postoperative complications and functional outcomes of intramedullary versus plate fixation (PF) in distal fibular fractures. A systematic review and meta-analysis was performed. The PubMed/MEDLINE, Embase, Cochrane, and CINAHL databases were searched for both randomized controlled trials and observational studies. A total of 26 studies was included, reporting on 1710 patients with a mean age of 51.6 years. Meta-analysis was performed on 8 comparative studies, including subgroup and sensitivity analyses on all outcomes. IMF was associated with significantly fewer wound related complications (odds ratio [OR], 0.11; 95% confidence interval [CI], 0.04 to 0.25; p < .01), implant removals (OR, 0.54; 95% CI, 0.31 to 0.93; p = .03), and nonunions (OR, 0.31; 95% CI, 0.15 to 0.62; p < .01). No differences were found regarding malunion (OR, 0.45; 95% CI, 0.17 to 1.21; p = .11) and the Olerud Molander Ankle Score for long-term functional outcome (mean difference, 9.56; 95% CI, 1.24 to 20.37; p = .08). Results of this study apply to a select group of patients, in which the advantages of minimal soft tissue damage by IMF are preferable to optimal fracture reduction by PF. IMF of distal fibular fractures resulted in fewer wound-related complications, implant removals, and nonunions compared with PF. Especially in elderly patients, patients with chronic comorbidity, and patients with compromised soft tissue, IMF may be preferred over PF.

Increased reduction in exsanguination rates leaves brain injury as the only major cause of death in blunt trauma

INTRODUCTION

Central nervous system (CNS) related injuries and exsanguination have been the most common causes of death in trauma for decades. Despite improvements in haemorrhage control in recent years exsanguination is still a major cause of death. We conducted a prospective database study to investigate the current incidence of haemorrhage related mortality.

MATERIALS AND METHODS

A prospective database study of all trauma patients admitted to an urban major trauma centre between January 2007 and December 2016 was conducted. All in-hospital trauma deaths were included. Cause of death was reviewed by a panel of trauma surgeons. Patients who were dead on arrival were excluded. Trends in demographics and outcome were analysed per year. Further, 2 time periods (2007-2012 and 2013-2016) were selected representing periods before and after implementation of haemostatic resuscitation and damage control procedures in our hospital to analyse cause of death into detail.

RESULTS

11,553 trauma patients were admitted, 596 patients (5.2%) died. Mean age of deceased patients was 61 years and 61% were male. Mechanism of injury (MOI) was blunt in 98% of cases. Mean ISS was 28 with head injury the most predominant injury (mean AIS head 3.4). There was no statistically significant difference in sex and MOI over time. Even though deceased patients were older in 2016 compared to 2007 (67 vs. 46 years, p < 0.001), mortality was lower in later years (p = 0.02). CNS related injury was the main cause of death in the whole decade; 58% of patients died of CNS in 2007-2012 compared to 76% of patients in 2013-2016 (p = 0.001). In 2007-2012 9% died of exsanguination compared to 3% in 2013-2016 (p = 0.001).

DISCUSSION

In this cohort in a major trauma centre death by exsanguination has decreased to 3% of trauma deaths. The proportion of traumatic brain injury has increased over time and has become the most common cause of death in blunt trauma. Besides on-going prevention of brain injury future studies should focus on treatment strategies preventing secondary damage of the brain once the injury has occurred.

Tertiary survey in polytrauma patients should be an ongoing process

INTRODUCTION

Due to prioritisation in the initial trauma care, non-life threatening injuries can be overlooked or temporally neglected. Polytrauma patients in particular might be at risk for delayed diagnosed injuries (DDI). Studies that solely focus on DDI in polytrauma patients are not available. Therefore the aim of this study was to analyze DDI and determine risk factors associated with DDI in polytrauma patients.

METHODS

In this single centre retrospective cohort study, patients were considered polytrauma when the Injury Severity Score was ≥ 16 as a result of injury in at least 2 body regions. Adult polytrauma patients admitted from 2007 until 2012 were identified. Hospital charts were reviewed to identify DDI.

RESULTS

1416 polytrauma patients were analyzed of which 12% had DDI. Most DDI were found during initial hospital admission after tertiary survey (63%). Extremities were the most affected regions for all types of DDI (78%) with the highest intervention rate (35%). Most prevalent DDI were fractures of the hand (54%) and foot (38%). In 2% of all patients a DDI was found after discharge, consisting mainly of injuries other than a fracture. High energy trauma mechanism (OR 1.8, 95% CI 1.2-2.7), abdominal injury (OR 1.5, 95% CI 1.1-2.1) and extremity injuries found during initial assessment (OR 2.3, 95% CI 1.6-3.3) were independent risk factors for DDI.

CONCLUSION

In polytrauma patients, most DDI were found during hospital admission but after tertiary survey. This demonstrates that the tertiary survey should be an ongoing process and thus repeated daily in polytrauma patients. Most frequent DDI were extremity injuries, especially injuries of the hand and foot.

Factors associated with pain intensity and physical limitations after lateral ankle sprains

BACKGROUND

Swelling, tenderness, and ecchymosis don't correlate with time to functional recovery in patients with a lateral ankle sprain. It is established that psychosocial factors such as symptoms of depression and low pain self-efficacy correlate with pain intensity and magnitude of limitations in patients with musculoskeletal disorders.

OBJECTIVE

We studied the correlation between pain self-efficacy or symptoms of depression and (1) ankle specific limitations and (2) pain intensity in patients with a lateral ankle sprain. Further we explored the correlation between estimation of sprain severity (grade) and (3) pain intensity or magnitude of ankle specific limitations.

DESIGN

Eighty-four patients with a lateral ankle sprain prospectively completed the Pain Self Efficacy Questionnaire, the Olerud Molander Ankle Score, Ordinal scale of Pain and the Patient Health Questionnaire-2 at enrollment and the Olerud Molander Ankle Score and the Ordinal scale of Pain three weeks after the injury. Factors associated with higher ankle specific limitations and symptoms were investigated in bivariable and multivariable analysis.

RESULTS

When accounting for confounding factors, greater self-efficacy (p=0.01) and older age (p<0.01) were significantly associated with greater ankle specific symptoms and limitations three weeks after the injury and explained 22% of the variability in ankle specific limitations and symptoms. There was no correlation between the grade of the sprain and pain intensity or ankle specific limitations or symptoms.

CONCLUSIONS

Psychosocial factors (adaptiveness in response to pain in particular) explain more of the variation in symptoms and limitations after ankle sprain than the degree of pathophysiology. The influence of adaptive illness descriptions and recovery strategies based on methods for improving self-efficacy (i.e. cognitive behavioral therapy) might enhance and speed recovery from ankle injuries and merit additional investigation.

LEVEL OF EVIDENCE

Level 2 prospective cohort study.

Long-term outcomes after operative treatment for tibial pilon fractures

OBJECTIVES

Aims of the present study were to establish generalizable outcome data on long-term functional outcomes and health-related quality of life (HRQoL) after operative treatment of pilon fractures on a large scale. Second, it was aimed to examine factors associated with these outcomes.

DESIGN

Retrospective cohort study with follow-up by questionnaire.

SETTING

Two level 1 trauma centers.

PATIENTS

Two hundred twenty-five of 480 eligible patients completed the survey (response rate 47%).

INTERVENTION

Open reduction internal fixation for tibial pilon fracture.

MAIN OUTCOME MEASUREMENTS

Ankle function measured using the Foot and Ankle Ability Measure, physical function using the Patient-Reported Outcomes Measurement System Physical Function (PROMIS PF, Short Form 10a) questionnaire and HRQoL using the EuroQol 5-Dimensions 3-Level (EQ-5D-3L) questionnaire.

RESULTS

At a medium follow-up of 82 months (82 (interquartile range (IQR), 45-120), median Foot and Ankle Ability Measure was 74 (IQR, 57-82), median PROMIS PF 49 (IQR, 44-57), median EQ-5D-3L 0.81 (IQR, 0.71-0.84). HRQoL was significantly lower compared to a reference population (P < .001). In multivariable regression analyses, smoking was associated with poorer HRQoL. Higher body mass index, deep infection, and lower HRQoL were associated with worse ankle function.

CONCLUSIONS

Long-term patient-reported outcomes after operative treatment of pilon fractures reveal impaired functionality and lower HRQoL compared to an uninjured reference population. As pilon fractures can have significant effects on a patient's life, patients should be counseled about the expected long-term outcomes to set realistic expectations. This study emphasizes the importance of obtaining both general and region-specific measures when evaluating outcomes after injury, in order to evaluate the injury of interest in the accurate context.

LEVEL OF EVIDENCE

Prognostic level III.

Complications After Surgical Treatment of Geriatric Ankle Fractures

The incidence of geriatric ankle fractures is rising and the potential for complications is high in this population. Little is known about factors associated with increased postoperative complications after surgical fixation of ankle fractures in older-age patients. The purpose of this retrospective cohort study was to assess the epidemiology and risk factors for complications after surgically treated ankle fractures in geriatric patients. All patients who were 65 years or older and had a surgically treated ankle fracture were included. Pilon fractures, patients who were initially treated conservatively or who had less than 1 month of follow-up were excluded. Postoperative complications, demographic-, fracture- and surgical data of 282 patients were recorded from two level 2 trauma centers between 2012 and 2017. A total of 87 (30.9%) patients developed a complication, of which wound related complications were most frequently reported. Superficial and deep wound infections were observed in 27 (9.6%) and 18 (6.4%) patients, respectively. Multivariate regression analysis demonstrated increased age to be an independent predictive variable for the occurrence of postoperative complications (odds ratio 1.04; 95% confidence interval 1.00-1.09), while cast immobilization for more than 2 weeks was a protective factor for the development of wound related complications (odds ratio 0.34; 95% confidence interval 0.17-0.66). In conclusion, the incidence of postoperative complications among geriatric patients after surgical treatment of ankle fractures is high and patients should be informed accordingly.

Fractures and dislocations of the hand in polytrauma patients: Incidence, injury pattern and functional outcome

INTRODUCTION

Injuries of the hand can cause significant functional impairment, diminished quality of life and delayed return to work. However, the incidence and functional outcome of hand injuries in polytrauma patients is currently unknown. The aim of this study was to determine the incidence, distribution and functional outcome of fractures and dislocation of the hand in polytrauma patients.

METHODS

A single centre retrospective cohort study was performed at a level 1 trauma centre. Polytrauma was defined as patients with an Injury Severity Score of 16 or higher. Fractures and dislocations to the hand were determined. All eligible polytrauma patients with hand injuries were included and a Quick Disability of Arm, Shoulder and Hand questionnaire (QDASH) and Patient-Rated Wrist/Hand Evaluation (PRWHE) were administered. Patients were contacted 1-6 years after trauma.

RESULTS

In a cohort of 2046 polytrauma patients 72 patients (3.5%) suffered a hand injury. The functional outcome scores of 52 patients (72%) were obtained. The Metacarpal (48%) and carpal (33%) bones were the most frequently affected. The median QDASH score for all patients with hand injury was 17 (IQR 0-31) and the PRWHE 14 (IQR 0-41). Patients with a concomitant upper extremity injury (p=0.002 for PRWHE, p0.006 for QDASH) and those with higher ISS scores (p=0.034 for PRWHE, QDASH not significant) had worse functional outcome scores. As an example, of the 5 patients with the worst outcome scores 3 suffered an isolated phalangeal injury, all had concomitant upper extremity injury or neurological injuries (3 plexus injuries, 1 severe brain injury).

CONCLUSION

The incidence of hand injuries in polytrauma patients is 3.5%, which is relatively low compared to a general trauma population. Metacarpal and carpal bones were most frequently affected. The functional extremity specific outcome scores are highly influenced by concomitant injuries (upper extremity injuries, neurological injuries and higher ISS).

Factors Associated With Wound- and Implant-Related Complications After Surgical Treatment of Ankle Fractures

We have described the epidemiology of complications after surgical treatment of ankle fractures and assessed which factors are associated with the most frequent complications. We conducted a retrospective cohort study at 2 level 2 and 1 level 1 trauma center in a single trauma region in the Netherlands. The study variables were collected from the electronic medical patient records; all ankle fractures were classified using the Lauge-Hansen classification, and the complications were recorded. A total of 989 patients were included from 3 hospitals, with 173 complications in 156 patients (15.8%). The most frequent complication was wound related, occurring in 101 patients (10.2%). Implant-related complications occurred in 44 patients (4.4%). Other complications, such as cast pressure spots, posttraumatic dystrophy, nonunion, impingement, and pneumonia occurred in 28 patients (2.8%). The 2 most important complications were further analyzed for risk factors. Multivariate analysis showed the risk factors for wound-related complications were advanced age, increased American Society of Anesthesiologists classification, smoking, right side symptomatic, open fracture, and initial external fixation. Most implant-related complications were caused by malreduction (n = 22) or untreated syndesmotic injury (n = 19). Malreduction was associated with supination eversion fractures (p = .059), and untreated syndesmotic injury occurred more often with pronation external rotation fractures (p < .001). The most frequent complications after ankle fracture surgery were wound- and implant-related complications. Postoperative wound-related complications were multifactorial and dependent on a combination of trauma-, patient-, and treatment-related factors. In contrast, implant-related complications resulted from the interaction between the fracture type and subsequent surgical treatment.

Polytrauma and High-energy Injury Mechanisms are Associated with Worse Patient-reported Outcomes After Distal Radius Fractures

BACKGROUND

Patient-reported outcomes (PROs) are increasingly relevant when evaluating the treatment of orthopaedic injuries. Little is known about how PROs may vary in the setting of polytrauma or secondary to high-energy injury mechanisms, even for common injuries such as distal radius fractures.

QUESTIONS/PURPOSES

(1) Are polytrauma and high-energy injury mechanisms associated with poorer long-term PROs (EuroQol Five Dimension Three Levels [EQ-5D-3L] and QuickDASH scores) after distal radius fractures? (2) What are the median EQ-5D-3L, EQ-VAS [EuroQol VAS], and QuickDASH scores for distal radius fractures in patients with polytrauma, high-energy monotrauma and low-energy monotrauma METHODS: This was a retrospective study with followup by questionnaire. Patients treated both surgically and conservatively for distal radius fractures at a single Level 1 trauma center between 2008 and 2015 were approached to complete questionnaires on health-related quality of life (HRQoL) (the EQ-5D-3L and the EQ-VAS) and wrist function (the QuickDASH). Patients were grouped according to those with polytrauma (Injury Severity Score [ISS] ≥ 16), high-energy trauma (ISS < 16), and low-energy trauma based on the ISS score and injury mechanism. Initially, 409 patients were identified, of whom 345 met the inclusion criteria for followup. Two hundred sixty-five patients responded (response rate, 77% for all patients; 75% for polytrauma patients; 76% for high-energy monotrauma; 78% for low-energy monotrauma (p = 0.799 for difference between the groups). There were no major differences in baseline characteristics between respondents and nonrespondents. The association between polytrauma and high-energy injury mechanisms and PROs was assessed using forward stepwise regression modeling after performing simple bivariate linear regression analyses to identify associations between individual factors and PROs. Median outcome scores were calculated and presented.

RESULTS

Polytrauma (intraarticular: β -0.11; 95% confidence interval [CI], -0.21 to -0.02]; p = 0.015) was associated with lower HRQoL and poorer wrist function (extraarticular: β 11.9; 95% CI, 0.4-23.4; p = 0.043; intraarticular: β 8.2; 95% CI, 2.1-14.3; p = 0.009). High-energy was associated with worse QuickDASH scores as well (extraarticular: β 9.5; 95% CI, 0.8-18.3; p = 0.033; intraarticular: β 11.8; 95% CI, 5.7-17.8; p < 0.001). For polytrauma, high-energy trauma, and low-energy trauma, the respective median EQ-5D-3L outcome scores were 0.84 (range, -0.33 to 1.00), 0.85 (range, 0.17-1.00), and 1.00 (range, 0.174-1.00). The VAS scores were 79 (range, 30-100), 80 (range, 50-100), and 80 (range, 40-100), and the QuickDASH scores were 7 (range, 0- 82), 11 (range, 0-73), and 5 (range, 0-66), respectively.

CONCLUSIONS

High-energy injury mechanisms and worse HRQoL scores were independently associated with slightly inferior wrist function after wrist fractures. Along with relatively well-known demographic and injury characteristics (gender and articular involvement), factors related to injury context (polytrauma, high-energy trauma) may account for differences in patient-reported wrist function after distal radius fractures. This information may be used to counsel patients who suffer a wrist fracture from polytrauma or high-energy trauma and to put their outcomes in context. Future research should prospectively explore whether our findings can be used to help providers to set better expectations on expected recovery.

Long-term follow-up after MIPO Philos plating for proximal humerus fractures

INTRODUCTION

Minimally invasive plate osteosynthesis (MIPO) has been described as a suitable technique for the treatment of proximal humerus fractures, but long-term functional results have never been reported. The aim of this study was to describe the long-term functional outcome and implant-related irritation after MIPO for proximal humerus fractures.

METHODS

A long-term prospective cohort analysis was performed on all patients treated for a proximal humerus fracture using MIPO with a Philos plate (Synthes, Switzerland) between December 2007 and October 2010. The primary outcome was the QuickDASH score. Secondary outcome measures were the subjective shoulder value (SSV), implant related irritation and implant removal.

RESULTS

Seventy-nine out of 97 patients (81%) with a mean age of 59 years were available for follow-up. The mean follow-up was 8.3 years (SD 0.8). The mean QuickDASH score was 5.6 (SD 14). The mean SSV was 92 (SD 11). Forty out of 79 patients (50.6%) had implant removal, and of those, 27/40 (67.5%) were due to implant-related irritation. On average, the implant was removed after 1.2 years (SD 0.5). In bivariate analysis, there was an association between the AO classification and the QuickDASH (p = 0.008).

CONCLUSION

Treatment of proximal humerus fractures using MIPO with Philos through a deltoid split approach showed promising results. A good function can be assumed due to the excellent scores of patient oriented questionnaires. However, about one-third of the patients will have a second operation for implant removal due to implant-related irritation.

Patient-Reported Outcomes and Complications After Surgical Fixation of 143 Proximal Phalanx Fractures

PURPOSE

Multiple methods exist to surgically fix unstable phalangeal fractures. Whereas these methods have different rates of complications or reoperation, it is not known whether these differences lead to changes in patient reported outcome. We compared patient-reported outcomes measures and complications of Kirschner wire (K-wire), lag-screw and plate fixation of proximal phalanx fractures (excluding the thumb).

METHODS

From 2010 to 2015, 159 patients with 159 proximal phalanx fractures were identified in 2 level 2 trauma centers and fixed with K-wires (44% of patients), lag-screws (26%), or plates (30%). Disabilities of the Arm, Shoulder, and Hand (DASH), and Patient-Rated Wrist/Hand Evaluation (PRWHE) and complications were assessed. In addition, subjective outcomes were assessed. Follow-up was achieved for 143 fractures (90%) and average time to follow-up was 3.4 years.

RESULTS

Mean DASH and PRWHE scores were 5.0 and 8.2, respectively. No differences in functional outcomes were found between fixation methods, although unplanned reoperation was more common in the plate fixation group (9 patients; 21%) than in the K-wire and lag-screw fixation groups (3 patients and 1 patient; 4.8 and 2.7%, respectively). We also found that K-wire fixation was associated with better aesthetic outcome than open reduction internal fixation.

CONCLUSIONS

Overall patient-reported outcomes measure scores were similar across fixation methods, and unplanned reoperation was more prevalent after plate fixation. In addition, we found that regardless of fracture pattern, percutaneous fixation with K-wires was often sufficient and associated with better aesthetic outcome than open reduction and internal fixation.

Severely injured patients benefit from in-house attending trauma surgeons

INTRODUCTION

There is continuous drive to optimize healthcare for the most severely injured patients. Although still under debate, a possible measure is to provide 24/7 in-house (IH) coverage by trauma surgeons. The aim of this study was to compare process-related outcomes for severely injured patients before and after transition of attendance policy from an out-of-hospital (OH) on-call attending trauma surgeon to an in-house attending trauma surgeon.

METHODS

Retrospective before-and-after study using prospectively gathered data in a Level 1 Trauma Center in the Netherlands. All trauma patients with an Injury Severity Score (ISS) >24 presenting to the emergency department for trauma before (2011-2012) and after (2014-2016) introduction of IH attendings were included. Primary outcome measures were the process-related outcomes Emergency Department length of stay (ED-LOS) and time to first intervention.

RESULTS

After implementation of IH trauma surgeons, ED-LOS decreased (p =  0.009). Time from the ED to the intensive care unit (ICU) for patients directly transferred to the ICU was significantly shorter with more than doubling of the percentage of patients that reached the ICU within an hour. The percentage of patients undergoing emergency surgery within 30 min nearly doubled as well, with a larger amount of patients undergoing CT imaging before emergency surgery.

CONCLUSIONS

Introduction of a 24/7 in-house attending trauma surgeon led to improved process-related outcomes for the most severely injured patients. There is clear benefit of continuous presence of physicians with sufficient experience in trauma care in hospitals treating large numbers of severely injured patients.

Epidemiology of distal radius fractures in polytrauma patients and the influence of high traumatic energy transfer

INTRODUCTION

For several extremity fractures differences in morphology, incidence rate and functional outcome were found when polytrauma patients were compared to patients with an isolated injury. This is not proven for distal radius fractures (DRF). Therefore, this study aimed to analyse fracture morphology in relation to energy transfer in both poly- and mono-trauma patients with a DRF.

METHODS

This was a retrospective cohort study. All patients aged 16 years and older with a DRF were included. Patients with an Injury Severity Score of 16 or higher were classified as polytrauma patients. Injuries were defined as high or low energy. All DRFs were classified using the AO/OTA fracture classification system.

RESULTS

A total of 830 patients with a DRF were included, 12% were polytrauma. The incidence rate of DRF in polytrauma patients was 3.5%. Ipsilateral upper extremity injury was found in >30% of polytrauma and high-energy monotrauma patients, compared to 5% in low-energy monotrauma patients. More type C DRF were found in polytrauma and high-energy monotrauma patients versus low-energy monotrauma patients. Operative intervention rates for all types of DRF were similar for polytrauma and high-energy monotrauma patients. Non-union rates were higher in polytrauma patients.

CONCLUSION

Higher energy mechanisms of injury, in polytrauma and high-energy monotrauma patients, were associated with more severe complex articular distal radius fractures and more ipsilateral upper extremity injuries. Polytrauma and high-energy monotrauma patient have a similar fracture morphology. However, polytrauma patients have in addition to more injured body regions also more non-union related interventions than high-energy monotrauma patients.
