Theadom A, Meehan L, McCallum S, Pacheco G. Mild traumatic brain injury increases engagement in criminal behaviour 10 years later: a case-control study. Front Psychiatry 2023; 14:1154707. [PMID: 37215665 PMCID: PMC10197901 DOI: 10.3389/fpsyt.2023.1154707] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Accepted: 04/07/2023] [Indexed: 05/24/2023] Open
Abstract
Introduction Sustaining a mild traumatic brain injury (mTBI) has been linked to increased criminal behaviour in later life. However, previous studies have not controlled for the number of injuries, gender, social deprivation, impact of past behaviour, or link to offence type. This study aims to determine if people who experienced a single or multiple mTBI have increased risk of criminal behaviour 10 years post-injury than matched orthopaedic controls. Methods This was a case control study of adults (aged >16 years) who experienced a medically diagnosed mTBI and controls who experienced a lower limb fracture (with no TBI) over a 12-month period (01/01/2003-31/12/2003). Participants were identified within Stats New Zealand's Integrated Data Infrastructure (national database including health and justice records). Participants who experienced a subsequent TBI (post-2003), who were not resident in New Zealand, and who died by 2013 were excluded. Case and controls were matched by age, sex, ethnicity, deprivation index and pre-injury criminal history. Results The study included N = 6,606 mTBI cases and N = 15,771 matched trauma controls. In the 10 years after injury, people experiencing a single mTBI had significantly higher numbers of violent charges (0.26 versus 0.21, p < 0.01) and violent convictions (0.16 versus 0.13, p < 0.05) but not for all court charges and convictions. Analysis of those with a history of prior mTBIs yielded larger effects, with significantly higher numbers of violent charges (0.57 versus 0.24, p < 0.05) and violent convictions (0.34 versus 0.14, p < 0.05). For males, the single mTBI case group had a significantly higher number of violent charges (0.40 versus 0.31, p < 0.05) and violent convictions (0.24 versus 0.20, p < 0.05) but this was not observed for females or all offence types. Discussion Experiencing multiple mTBIs over the lifetime increases the number of subsequent violence-related charges and convictions but not for all offence types in males but not for females. These findings highlight the need for improved recognition and treatment of mTBI to prevent future engagement in antisocial behaviour.

The Putative Role of Neuroinflammation in the Interaction between Traumatic Brain Injuries, Sleep, Pain and Other Neuropsychiatric Outcomes: A State-of-the-Art Review. J Clin Med 2023; 12:jcm12051793. [PMID: 36902580 PMCID: PMC10002551 DOI: 10.3390/jcm12051793] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 02/15/2023] [Accepted: 02/21/2023] [Indexed: 02/25/2023] Open
Abstract
Sleep disturbances are widely prevalent following a traumatic brain injury (TBI) and have the potential to contribute to numerous post-traumatic physiological, psychological, and cognitive difficulties developing chronically, including chronic pain. An important pathophysiological mechanism involved in the recovery of TBI is neuroinflammation, which leads to many downstream consequences. While neuroinflammation is a process that can be both beneficial and detrimental to individuals' recovery after sustaining a TBI, recent evidence suggests that neuroinflammation may worsen outcomes in traumatically injured patients, as well as exacerbate the deleterious consequences of sleep disturbances. Additionally, a bidirectional relationship between neuroinflammation and sleep has been described, where neuroinflammation plays a role in sleep regulation and, in turn, poor sleep promotes neuroinflammation. Given the complexity of this interplay, this review aims to clarify the role of neuroinflammation in the relationship between sleep and TBI, with an emphasis on long-term outcomes such as pain, mood disorders, cognitive dysfunctions, and elevated risk of Alzheimer's disease and dementia. In addition, some management strategies and novel treatment targeting sleep and neuroinflammation will be discussed in order to establish an effective approach to mitigate long-term outcomes after TBI.

Clin Orthop Relat Res 2023; 481:132-142. [PMID: 36200843 PMCID: PMC9750668 DOI: 10.1097/corr.0000000000002329] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Accepted: 06/28/2022] [Indexed: 11/05/2022]
Abstract
BACKGROUND Individuals in violent intimate relationships are at a high risk of sustaining both orthopaedic fractures and traumatic brain injury (TBI), and the fracture clinic may be the first place that concurrent intimate partner violence (IPV) and TBI are recognized. Both IPV and TBI can affect all aspects of fracture management, but prevalence of TBI and comorbid TBI and IPV is unknown. QUESTIONS/PURPOSES (1) What are the previous-year and lifetime prevalence of IPV and TBI in women presenting to an outpatient orthopaedic fracture clinic? (2) What are the conditional probabilities of TBI in the presence of IPV and the reverse, to explore whether screening for one condition could effectively identify patients with the other? (3) Do patients with TBI, IPV, or both have worse neurobehavioral symptoms than patients without TBI and IPV? METHODS The study was completed in the fracture clinic at a community Level 1 trauma center in Southern Ontario from July 2018 to March 2019 and included patients seen by three orthopaedic surgeons. Inclusion criteria were self-identification as a woman, age 18 years or older, and the ability to complete forms in English without assistance from the person who brought them to the clinic (for participant safety and privacy). We invited 263 women to participate: 22 were ineligible (for example, they were patients of a surgeon who was not on the study protocol), 87 declined before hearing the topic of the study, and data from eight were excluded because the data were incomplete or lost. Complete data were obtained from 146 participants. Participants' mean age was 52 ± 16 years, and the most common diagnosis was upper or lower limb fracture. Prevalence of IPV was calculated as the number of women who answered "sometimes" or "often" to direct questions from the Woman Abuse Screening Tool, which asks about physical, emotional, and sexual abuse in the past year or person's lifetime. The prevalence of TBI was calculated as the number of women who reported at least one head or neck injury that resulted in feeling dazed or confused or in loss of consciousness lasting 30 minutes or less on the Ohio State University Traumatic Brain Injury Identification Method, a standardized procedure for eliciting lifetime history of TBI through a 3- to 5-minute structured interview. Conditional probabilities were calculated using a Bayesian analysis. Neurobehavioral symptoms were characterized using the Neurobehavioral Symptom Inventory, a standard self-report measure of everyday emotional, somatic, and cognitive complaints after TBI, with total scores compared across groups using a one-way ANOVA. RESULTS Previous-year prevalence of physical IPV was 7% (10 of 146), and lifetime prevalence was 28% (41 of 146). Previous-year prevalence of TBI was 8% (12 of 146), and lifetime prevalence was 49% (72 of 146). The probability of TBI in the presence of IPV was 0.77, and probability of IPV in the presence of TBI was 0.36. Thus, screening for IPV identified proportionately more patients with TBI than screening for TBI, but the reverse was not true. Neurobehavioral Symptom Inventory scores were higher (more symptoms) in patients with TBI only (23 ± 16) than those with fractures only (12 ± 11, mean difference 11 [95% CI 8 to 18]; p < 0.001), in those with IPV only (17 ± 11) versus fractures only (mean difference 5 [95% CI -1 to -11]; p < 0.05), and in those with both TBI and IPV (25 ± 14) than with fractures only (mean difference 13 [95% CI 8 to 18]; p < 0.001) or those with IPV alone (17 ± 11, mean difference 8 [95% CI -1 to 16]; p < 0.05). CONCLUSION Using a brief screening interview, we identified a high self-reported prevalence of TBI and IPV alone, consistent with previous studies, and a novel finding of high comorbidity of IPV and TBI. Given that the fracture clinic may be the first healthcare contact for women with IPV and TBI, especially mild TBI associated with IPV, we recommend educating frontline staff on how to identify IPV and TBI as well as implementing brief screening and referral and universal design modifications that support effective, efficient, and accurate communication patients with TBI-related cognitive and communication challenges.

Traumatic brain injuries are ignored or discriminated in prospective clinical trials on shoulder fractures: a systematic review. INTERNATIONAL ORTHOPAEDICS 2023; 47:17-50. [PMID: 36435944 DOI: 10.1007/s00264-022-05642-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 10/10/2022] [Indexed: 11/28/2022]
Abstract
PURPOSE Current literature suggests a significant epidemiological association between traumatic brain injury (TBI) and proximal upper limb fractures in addition to major clinical consequences. A systematic review was conducted to assess how TBI is taken into consideration in interventional studies on shoulder fractures. METHODS The following data sources were used: MEDLINE, EMBASE, EBM Reviews, CINAHL, and OpenGrey databases. Study selection included interventional randomized clinical trials and prospective cohort studies on shoulder fractures published in English or French between 2008 and 2020. Studies on pathologic fractures, chronic fracture complications, nonhuman subjects, and biomechanics were excluded. Articles were reviewed by two independent authors according to the PRISMA guidelines. Baseline characteristics, exclusion criteria, and input relevant to TBI were recorded. Methodological quality was assessed with the Cochrane risk of bias tool for randomized clinical trials and the Newcastle-Ottawa Scale for cohort studies. RESULTS One-hundred-thirteen studies met the inclusion criteria. None discussed the possible impact of TBI on their results. Only three (2.7%) studies considered TBI relevant and included these patients in their cohort. Furthermore, 43/113 (38.1%) excluded patients with injuries or mechanisms strongly related to traumatic brain injuries: head injuries (4); moderate and/or severe TBI (7); high energy traumas (3); Polytrauma subjects (33). CONCLUSION TBI are ignored or discriminated in prospective clinical trials on shoulder fractures. The exclusion of these cases impacts generalizability as their prevalence is significant. Considering the major impact of TBI on important outcomes, its presence should always be assessed to ensure high quality evidence. LEVEL OF EVIDENCE Systematic Review, Therapeutic Level II.

Abstract
Traumatic brain injury (TBI) is characterized by cellular damage and inflammation in lesioned brain tissue. Ferulic acid has been shown to have a melioration effect on neurological functions. However, the active pharmacological effects and the underlying mechanisms of ferulic acid against TBI remain unclear. On the basis of network pharmacology and molecular docking methodology, this study aimed to investigate the beneficial effects of ferulic acid in treating TBI, and characterized the detailed biotargets and mechanisms of these actions. The identified core targets were validated via in silico simulation. We identified 91 overlapping targets associated with ferulic acid and TBI. In-silico simulation analysis validated the putative core targets of tumor protein p53, mitogen-activated protein kinase (MAPK) 1, and estrogen receptor 1. The Gene Ontology-enriched annotations and findings were largely associated with cell proliferation, apoptosis, and inflammation in nerve cells. Additional Kyoto Encyclopedia of Genes and Genomes enrichment analysis unmasked the pharmacological pathways of ferulic acid in treating TBI, including the MAPK signaling pathway and hypoxia-inducible factor-1 signaling pathway. Bioinformatic analyses and findings provide a new preclinical strategy for revealing the core targets and network pathways of ferulic acid in treating TBI. Moreover, some bioinformatic findings were computationally validated in silico for exhibiting the neuroprotective action of ferulic acid against TBI.

Abstract
BACKGROUND Traumatic head injury (THI) due to road traffic accidents (RTAs) is a global health problem. Studies exploring the association between RTA-related THI and concurrent orthopedic fractures are lacking. We aim to provide a detailed analysis of this association and its impact on inhospital outcomes. METHODS Retrospective analysis of RTA-related THI associated with orthopedic fractures admitted to a large tertiary center, Southwest, Saudi Arabia, over ten years. Descriptive statistics for participant demographics and clinical outcomes were represented by percentages. The associations between head injury diagnosis or orthopedic fractures region and patient demographics are analyzed using the Chi-square test. Post hoc analysis for the significant Chi-square values was carried out by calculating the significant adjusted residuals. Adjust p value was obtained by using the Benjamini-Hochberg procedure to control for multiplicity testing. A p value less than 0.05 was considered statistically significant. RESULTS Concurrent orthopedic fractures are present in one-tenth of RTA-related THI. The cohort was dominated by young males, with 46.5% of the population between 18 and 29 years old. There was a significant association between the head injury diagnosis and the region of orthopedic fracture (p = 0.028). The type of head injury had significant associations with mortality and duration of hospital stay (p = 0.039 and p = 0.037, respectively). The region of orthopedic fracture significantly (p = 0.018) affected the duration of hospital stay, with fractures in the clavicle/shoulder region significantly (p = 0.035) having a short course of hospital admission. CONCLUSION Orthopedic fractures concomitant with RTA-related THI are common. The associations between the two injuries tend to happen in specific patterns. The inhospital stay duration and mortality significantly correlated with the site of the head or orthopedic injury. Knowledge of these patterns improves the care of THI victims, triaging, and resource allocations.

Abstract
Introduction: The neurocognitive outcomes of sustaining a mild traumatic brain injury (mTBI) during late adulthood are vastly understudied. In young, asymptomatic adults, mTBI-related synaptic plasticity alterations have been associated with persistent implicit motor sequence learning impairments outlasting the usual cognitive recovery period. The current study examined whether uncomplicated mTBI sustained during late adulthood could exert persistent deleterious consequences on implicit motor sequence learning.Method: Thirty participants (aged 50-70 years) who experienced an uncomplicated mTBI within 3 to 24 months of testing, and 40 age-, sex- and education-equivalent healthy controls performed an implicit serial reaction time task (SRT task). The SRT task consisted of 10 blocks of a repeating sequence embedded among 4 random blocks. Participants also completed a battery of standardized neuropsychological tests of attention, memory and executive functioning.Results: While both mTBI participants and controls showed significant implicit motor sequence learning effects, the mTBI group achieved a lower level of competence at performing the SRT task as evidenced by smaller gains in reaction times across the 10 training blocks of the repeating sequence. The time elapsed since the injury was unrelated to implicit motor learning effects. There was no evidence of a persistent effect of mTBI on any neuropsychological domain compared to controls.Conclusions: Findings from this study suggest that a single mTBI sustained during older age may have persistent repercussions on training-dependent motor sequence learning capacity outlasting the recovery of mTBI symptoms and gold-standard neuropsychological tests performance.

Abstract
This pilot study explores the possibility of predicting post-concussion symptom recovery at one week post-injury using only objective diffusion tensor imaging (DTI) data inputs to a novel artificial intelligence (AI) system composed of Genetic Fuzzy Trees (GFT). Forty-three adolescents age 11 to 16 years with either mild traumatic brain injury or traumatic orthopedic injury were enrolled on presentation to the emergency department. Participants received a DTI scan three days post-injury, and their symptoms were assessed by the Post-Concussion Symptom Scale (PCSS) at 6 h and one week post-injury. The GFT system was trained using one-week total PCSS scores, 48 volumetric magnetic resonance imaging inputs, and 192 DTI inputs per participant over 225 training runs. Each training run contained a randomly selected 80% of the total sample followed by a 20% validation run. Over a different randomly selected sample distribution, GFT was also compared with six common classification methods. The cascading GFT structure controlled an effectively infinite solution space that classified participants as recovered or not recovered significantly better than chance. It demonstrated 100% and 62% classification accuracy in training and validation, respectively, better than any of the six comparison methods. Recovery sensitivity and specificity were 59% and 65% in the GFT validation set, respectively. These results provide initial evidence for the effectiveness of a GFT system to make clinical predictions of trauma symptom recovery using objective brain measures. Although clinical and research applications will necessitate additional optimization of the system, these results highlight the future promise of AI in acute care.

Crosstalk of Brain and Bone-Clinical Observations and Their Molecular Bases. Int J Mol Sci 2020; 21:ijms21144946.

Abstract
As brain and bone disorders represent major health issues worldwide, substantial clinical investigations demonstrated a bidirectional crosstalk on several levels, mechanistically linking both apparently unrelated organs. While multiple stress, mood and neurodegenerative brain disorders are associated with osteoporosis, rare genetic skeletal diseases display impaired brain development and function. Along with brain and bone pathologies, particularly trauma events highlight the strong interaction of both organs. This review summarizes clinical and experimental observations reported for the crosstalk of brain and bone, followed by a detailed overview of their molecular bases. While brain-derived molecules affecting bone include central regulators, transmitters of the sympathetic, parasympathetic and sensory nervous system, bone-derived mediators altering brain function are released from bone cells and the bone marrow. Although the main pathways of the brain-bone crosstalk remain ‘efferent’, signaling from brain to bone, this review emphasizes the emergence of bone as a crucial ‘afferent’ regulator of cerebral development, function and pathophysiology. Therefore, unraveling the physiological and pathological bases of brain-bone interactions revealed promising pharmacologic targets and novel treatment strategies promoting concurrent brain and bone recovery.

Investigating the incidence and magnitude of heterotopic ossification with and without joints involvement in patients with a limb fracture and mild traumatic brain injury. Bone Rep 2019; 11:100222. [PMID: 31463337 PMCID: PMC6706636 DOI: 10.1016/j.bonr.2019.100222] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Revised: 07/25/2019] [Accepted: 08/12/2019] [Indexed: 01/01/2023] Open
Abstract
Objectives This study seeks to evaluate the incidence rate of heterotopic ossification (HO) formation in patients afflicted by an isolated limb fracture (ILF) and a concomitant mild traumatic brain injury (mTBI). Methods The current study is an observational study including ILF patients with or without a concomitant mTBI recruited from an orthopedic clinic of a Level 1 Trauma Hospital. Patients were diagnosed with a mTBI according to the American Congress of Rehabilitation Medicine (ACRM) criteria. Radiographs taken on average 3 months post-trauma were analyzed separately by two distinct specialists for the presence of HO proximally to the fracture site (joints or extra joints). Both raters referred to Brooker's and Della's Valle's classification to establish signs of HO. First, analyses were conducted for the full sample. Secondly, a matched cohort was used in order to control for specific factors, namely age, sex, type of injury, and time elapsed between the accident and the analyzed radiograph. Results The full sample included a total of 183 patients with an ILF (94 females; 47.5 years old), of which 50 had a concomitant mTBI and 133 without. Radiographic evidence of HO was significantly higher in patients with an ILF and a mTBI compared to ILF patients (X2 = 6.50; p = 0.01). The matched cohort consisted of 94 participants (i.e.; 47 patients from the ILF + mTBI group and 47 patients from the ILF group). Again, ILF + mTBI patients presented significantly higher rates of HO signs in comparison to ILF patients (X2 = 3.69; p = 0.04). Presence of HO was associated with prolonged delays to return to work (RTW) only in ILF + mTBI patients (F = 4.055; p = 0.05) but not in ILF patients (F = 0.823; p = 0.37). Conclusions Study findings suggest that rates of HO are significantly higher proximally to fracture sites when ILF patients sustain a concomitant mTBI, even after controlling for factors known to influence HO. Moreover, results show that HO is associated with a prolonged RTW only in ILF patients with a concomitant mTBI but not in ILF-only patients. The impact of mTBI on HO formation warrants further attention to detect early signs of HO, to identify shared physiopathological mechanisms and, ultimately, to design targeted therapies. Rates of HO are significantly higher in patients with a fracture and a mTBI compared to patients with a fracture only. Factors such as sex, age, joint involvement, and surgical procedures were unrelated to the detection of signs of HO Presence of HO negatively impacted RTW delays in patients with a concomitant mTBI

The clinical utility of repetitive transcranial magnetic stimulation in reducing the risks of transitioning from acute to chronic pain in traumatically injured patients.

Abstract
Pain is a multifaceted condition and a major ongoing challenge for healthcare professionals having to treat patients in whom pain put them at risk of developing other conditions. Significant efforts have been invested in both clinical and research settings in an attempt to demystify the mechanisms at stake and develop optimal treatments as well as to reduce individual and societal costs. It is now universally accepted that neuroinflammation and central sensitization are two key underlying factors causing pain chronification as they result from maladaptive central nervous system plasticity. Recent research has shown that the mechanisms of action of repetitive transcranial magnetic stimulation (rTMS) make it a particularly promising avenue in treating various pain conditions. This review will first discuss the contribution of neuroinflammation and central sensitization in the transition from acute to chronic pain in traumatically injured patients. A detailed discussion on how rTMS may allow the restoration from maladaptive plasticity in addition to breaking down the chain of events leading to pain chronification will follow. Lastly, this review will provide a theoretical framework of what might constitute optimal rTMS modalities in dealing with pain symptoms in traumatically injured patients based on an integrated perspective of the physiopathological mechanisms underlying pain.

Abstract
Traumatic brain injury (TBI) is the cause for long-term disability in more than 3 million patients in the US alone, with chronic pain being the most frequently reported complain. To date, predisposing mechanisms for chronic pain in TBI patients are largely unknown. Psychological disorders, including post-traumatic stress disorder, depression and anxiety following TBI are commonly reported comorbidities to post-traumatic pain. Long term consequences can be debilitating and affect quality of life even when the injury is mild. In this review, we present the most commonly reported chronic pain conditions across the spectrum of severity of TBI, mainly focusing on mild TBI. We discuss chronic post- traumatic headaches, widespread pain as well as post-traumatic central pain. We discuss pain in the context of injury severity and military versus civilian populations. We are only starting to understand the biological mechanisms behind post-traumatic pain and associated psychological distress following TBI, with genetic, biochemical and imaging studies pointing to the dopaminergic, neurotrophic factors and the role of Apolipoprotein. Physiological and neurological mechanisms are proposed to partially explain this interaction between post-traumatic pain and psychological distress. Nevertheless, the evidence for the role of structural brain damage remains incomplete and to a large extent debatable, as it is still difficult to establish clear causality between brain trauma and chronic pain. Finally, general aspects of management of chronic pain post-TBI are addressed.

Abstract
Traumatic brain injury (TBI) leads to long-term cognitive, behavioral, affective deficits, and increase neurodegenerative diseases. It is only in recent years that there is growing awareness that TBI even in its milder form poses long-term health consequences to not only the brain but to other organ systems. Also, the concept that hormonal signals and neural circuits that originate in the hypothalamus play key roles in regulating skeletal system is gaining recognition based on recent mouse genetic studies. Accordingly, many TBI patients have also presented with hormonal dysfunction, increased skeletal fragility, and increased risk of skeletal diseases. Research from animal models suggests that TBI may exacerbate the activation and inactivation of molecular pathways leading to changes in both osteogenesis and bone destruction. TBI has also been found to induce the formation of heterotopic ossification and increased callus formation at sites of muscle or fracture injury through increased vascularization and activation of systemic factors. Recent studies also suggest that the disruption of endocrine factors and neuropeptides caused by TBI may induce adverse skeletal effects. This review will discuss the long-term consequences of TBI on the skeletal system and TBI-induced signaling pathways that contribute to the formation of ectopic bone, altered fracture healing, and reduced bone mass.

Abstract
The design of clinical studies in orthopedic traumatology is challenging in several respects. In this era of evidence-based medicine, the pressure is high to choose our treatments solely based on randomized controlled studies. This type of study, when well-constructed, makes it possible to discern the best treatment for a specific fracture in a given group of patients and in connection with a specific outcome. Randomized controlled trials require a lot of resources and are not designed to answer all research questions. Observational studies, such as case-control studies, prospective cohort studies, and cross-sectional studies, also have a role to play in improving scientific knowledge in orthopedic trauma. Regardless of the type of study chosen, the researcher must follow a strict methodology that conforms to practice guidelines in order to ensure the study's conclusions are valid. The guidelines for randomized studies can be found at http://www.consort-statement.org and at http://www.strobe-statement.org for cohort studies. It is also very important to register randomized studies before they begin on a website such as http://www.clinicaltrials.gov, since registration is an increasingly common requirement when submitting an article for publication. Although this preparation is relatively cumbersome, it is essential for producing articles that meet modern scientific criteria.

Abstract
BACKGROUND The objective is to explore the effects of concomitant mild traumatic brain injury (mTBI) on return to work (RTW), among patients suffering from an isolated limb fracture. This follow-up study included a total of 170 working age subjects with an isolated limb fracture, and was conducted in a phone interview approximately 1-year post trauma. 41 had experienced an mTBI and 129 did not. METHODS Data were obtained through a phone interview conducted on average 20.7 months (SD = 9.6 months) post-accident. The main outcome measure was the number of days taken to RTW after the injury. Demographic information was also gathered during the phone interview. Workers' compensation status was obtained through the hospitals' orthopaedic clinic data. RESULTS The mTBI group took on average 329.7 days (SD = 298.0) to RTW after the injury, as opposed to 150.3 days (SD = 171.3) for the control group (p < 0.001). After excluding patients who received workers' compensation, the mTBI group still missed significantly more days of work (M = 299.4 days; SD = 333.0) than the control group (M = 105.2 days; SD = 121.6) (p < 0.0001). CONCLUSION This study shows that mTBI increases work disability by preventing working-age individuals from rapidly returning to work.

Abstract
OBJECTIVES This study seeks to evaluate the effects of a mild traumatic brain injury (mTBI) on pain in patients with an isolated limb fracture (ILF) when compared to a matched cohort group with no mTBI (control group). PATIENTS AND METHODS All subjects included in this observational study suffered from an ILF. Groups were matched according to the type of injury, sex, age, and time since the accident. Main outcome measurements were: Standardized semi-structured interviews at follow-up of a Level I Trauma Center, and a questionnaire on fracture-related pain symptoms. Factors susceptible to influence the perception of pain, such as age, sex, severity of post-concussive symptoms, and worker compensation were also assessed. RESULTS A total of 68 subjects (36 females; 45 years old) with an ILF were selected, 34 with a comorbid mTBI and 34 without (24/34 with an upper limb fracture per group, 71% of total sample). Patients with mTBI and an ILF reported significantly higher pain scores at the time of assessment (mean: 49days, SD: 34.9), compared to the control group (p<0.0001; mean difference 2.8, 95% confidence interval 1.8-4.0). Correlational analyses show no significant association between the level of pain and factors such as age, sex, severity of post-concussive symptoms, and worker compensation. CONCLUSIONS Results suggest that mTBI exacerbate perception of pain in the acute phase when occurring with an ILF, and were not explained by age, sex, post-concussive symptoms, or worker compensation. Rather, it appears possible that neurological sequelae induced by mTBI may interfere with the normal recovery of pain following trauma.
