Return to Play After Hook of Hamate Fracture: A Systematic Review and Meta-Analysis.

In athletes, a hook of hamate fracture is concerning in terms of time to return to sport and effect on performance upon return. This study aims to analyze the treatment of hook of hamate fractures in athletes to determine their rates of return to play, timelines of recovery, and performance level upon return to play. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to perform this analysis. The PubMed database was queried to perform the literature search. Data were pooled and analyzed. P values <.05 were considered significant. Data were analyzed using the Comprehensive Meta-Analysis software to determine heterogeneity. Twenty studies with 823 patients sustaining hook of hamate fractures that reported any competitive level of play were included in the analysis. Of the 823 patients, 778 (94.5%) were able to return to play with 91.2% (506/555) of patients demonstrating similar or improved performance. The mean time to return to play was 45 days (range: 21-168 days). Treatment included surgical excision for 787 patients (95.6%), open reduction and internal fixation for 18 patients (2.2%), stress reduction/casting for 13 patients (1.6%), and loss to follow-up or surgery refusal for 5 patients (0.6%). A very high number of athletes return to play following a hook of hamate fracture at the same or improved level of performance. In our study, the majority of injuries were treated with surgical excision of the fractured hook of hamate fragment. Most athletes returned to their sport at an average of 45 days.

Clinical and Radiographic Outcomes of Anterior Lumbar Interbody Fusion With Anterior Plate Fixation.

Reports on the outcomes following instrumented anterior lumbar interbody fusion (ALIF) with anterior plate fixation are limited. The aim of this study was to assess the clinical and radiographic outcomes of patients undergoing ALIF with anterior plate fixation. Methods: Medical records and radiographic imaging were reviewed for 100 patients who received ALIF with anterior plate fixation between 2008 to 2021 and completed at least one year of follow-up and postoperative imaging. Prospectively collected patient data included indication for surgery, BMI, age, number and location of levels treated, complications, reoperation rates, fusion rate, and measurements of global lordosis, disc space height, and segmental angulation. Results: A total of 100 patients were included in this study. The mean length of follow-up was 81.37 months. Changes in preoperative-to-postoperative Oswestry Disability Index (ODI) and Visual Analog Score (VAS) demonstrated improvements of 30.86% and 18.56%, respectively. Major vascular injuries occurred in 3% of the cases. A hardware failure rate of 5% was observed. The reoperation rate was 10%. The radiographic fusion rate derived from computed tomography (CT) and plain film was 95.45% and 88.87%, respectively. Postoperative global lordosis demonstrated a 6.08% increase. Postoperative segmental angulation measurements increased by 57.74%. No statistically significant differences in clinical or radiographic outcomes were observed based on the spine level of fusion or the number of fusions performed. Conclusions: ALIF with anterior plate fixation achieved an adequate fusion rate with improvements in ODI and VAS scores meeting minimal clinically important difference thresholds. Postoperative disc space heights demonstrated significant improvements compared to preoperative measurements.

Should Pediatric Surgical Oncologists Receive Training in Vascular Surgery ? A Practice Survey Report From the International Society of Paediatric Surgical Oncology (IPSO)

BackgroundIs vascular training in paediatric surgical oncology considered desirable ? MethodsA voluntary survey of work practice was undertaken with the surgeon membership of The International Society Of Paediatric Surgical Oncology (IPSO) using a structured designed questionnaire. ResultsA total of 149 IPSO surgeon members completed the survey. 57% (N = 84) of surgeons surveyed had no specific training in vascular surgery. 43% surgeons (N = 63) stated they had acquired some skills in residency training and/or with transplantation surgery. 65% (N = 96) of respondent surgeons stated that vascular surgical training must be incorporated into pediatric surgical oncology training and 27% (N = 40) agreed that it was considered desirable. 89% (N = 133) of surgeon respondents had encountered major vascular injury during work practice while operating on pediatric solid tumors. Vascular injury repairs were undertaken and attempted by pediatric surgeons though expert assistance of vascular surgeons proved crucially essential in many instances. Emergent operations included patch repairs, vessel ligation techniques and insertion of vascular graft prostheses. Interventional radiology services to arrest life-threatening hemorrhage were also reportedly utilized by respondents. ConclusionVascular injuries have significant potential for devastating patient outcomes including never event ‘mortality’. The IPSO surgeon survey highlights that there are visible ‘gaps’ in skills training. Training to be a pediatric oncology surgeon must incorporate acquisition of skill sets proficiency in vascular surgery.

Does Playing Football (Soccer) Really Increase the Risk of Knee Osteoarthritis? A Systematic Review and Meta-analysis.

OBJECTIVE: To evaluate the relationship between football (soccer) participation and tibiofemoral knee osteoarthritis (OA), considering the influence of competitive level and previous knee injuries. DESIGN: Etiology systematic review with meta-analysis. LITERATURE SEARCH: PubMed, Embase, AMED, and Cochrane were searched for relevant publications. STUDY SELECTION CRITERIA: Studies of football players that included a control group consisting of mainly sedentary nonfootball players, and the relationship of knee OA, were considered. The studies had to report radiographically verified knee OA and specify football activity. DATA SYNTHESIS: Eleven studies, involving 1805 football players and 4022 control individuals were included. Subgroups consisting of data regarding level of play and previous injuries were also synthesized. RESULTS: The overall prevalence of knee OA among football players was increased among professional and recreational players, compared with controls. When knee injuries were excluded, there was no difference in knee OA between football players and controls (OR = 1.25; 95% CI: 0.61, 2.54). Football players with a previous knee injury had a greater risk of knee OA when compared with football players with no history of previous knee injury (OR = 4.16; 95% CI: 1.97, 8.77). CONCLUSION: Football players were at increased risk of knee OA. However, after excluding participants with a history of previous knee injury, there were no differences in knee OA between football players and controls. Previous knee injury was important for developing knee OA. Playing football, in the absence of major knee injuries, did not increase the risk of knee OA. J Orthop Sports Phys Ther 2024;54(5):1-12.

Injury-severity analysis of crashes involving defective vehicles and accounting for the underlying socioeconomic mediators

Crashes occur from a combination of factors related to the driver, roadway, and vehicle factors. The impact of vehicles on road crashes is a critical consideration within road safety analysis, even though not much studies have been conducted in this area. This study assessed how various vehicle and other crash factors are significantly associated with crash outcomes. To do this, historical vehicle defect-related crashes were obtained for the state of Alabama from 2016 to 2020. After data cleaning, a crash injury severity model was developed using the random parameters multinomial logit with heterogeneity in means approach to account for possible unobserved heterogeneity in the data. A spatial analysis was further conducted to better understand vehicle defect crashes as a broader societal issue and potentially explore their connection with the socio-demographic characteristics of the drivers of these vehicles. The preliminary data analysis showed that brake and tire defects accounted for about 65% of the vehicle defects associated with the crashes. The model estimation results revealed that improper tread depth and headlight defects were associated with major injury outcomes, while brake defects were more associated with minor injuries. Also, crashes associated with speeding, drunk driving, failure to use seatbelts, and those that occurred on curved roads left with downgrades were likely to result in major injuries. Findings from the spatial analysis showed that postal codes with higher median incomes are more likely to record lower vehicle defect-related crashes, unlike those that have higher proportions of females and African Americans. The study's findings provide data-driven evidence for sustained safety campaigns, workshops, and training on basic vehicle maintenance practices in the low-income communities in the state.

Major trauma in working-age adults in New Zealand.

To describe the demographic and injury profile of major trauma among 20-65-year-old New Zealanders. A retrospective analysis of routinely collected data from the New Zealand Major Trauma Registry for the period 1 July 2017 to 30 June 2020 was conducted. Sex, age and ethnicity-based rates were then calculated using census-based population estimates to compare the rates of injury across different demographic groups. Of the 4,186 major trauma incidents among 20-65-year-olds in New Zealand during the 3-year period reviewed, 235 died (5.6%). Males accounted for 77% of those injured. Māori (New Zealand's Indigenous population) had significantly higher rates of major trauma (79.2 per 100,000; 95% confidence interval [CI] 74.4-84.3) compared to non-Māori (44.4 per 100,000; 95% CI 42.9-46.0). The most common cause of injury was transport-related incidents (63%; n=2,632/4,186), followed by falls (19%; n=788/4,186). Demographic characteristics have a significant relationship with major trauma injuries among 20-65-year-old New Zealanders. Continued injury prevention efforts focussing on males, Māori and transport incidents are required. Interventions that improve the safety of roads, such as lane separators, speed limits and raised intersections, should be implemented in high-crash-risk areas to reduce risk.

Venoarterial Extracorporeal Membrane Oxygenation Implementation in Septic Shock Rat Model.

Septic shock, a global health concern, boasts high mortality rates. Research exploring the efficacy of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in septic shock remains limited. Our study aimed to establish a rodent model employing VA-ECMO in septic shock rats, assessing the therapeutic impact of VA-ECMO on septic shock. Nineteen Sprague-Dawley rats were randomly assigned to sham, septic shock, and (septic shock + VA-ECMO; SSE) groups. Septic shock was induced by intravenous lipopolysaccharides, confirmed by a mean arterial pressure drop to 25-30% of baseline. Rats in the SSE group received 2 hours of VA-ECMO support and 60 minutes of post-weaning ventilation. Sham and septic shock groups underwent mechanical ventilation for equivalent durations. Invasive mean arterial pressure monitoring, echocardiographic examinations, and blood gas analysis revealed the efficacy of VA-ECMO in restoring circulation and ensuring adequate tissue oxygenation in septic shock rats. Post-experiment pathology exhibited the potential of VA-ECMO in mitigating major organ injury. In summary, our study successfully established a stable septic shock rat model with the implementation of VA-ECMO, offering a valuable platform to explore molecular mechanisms underlying VA-ECMO's impact on septic shock.

Hollow viscus perforation in blunt abdominal trauma: A 14-year experience from a trauma center.

Isolated perforations of hollow viscus (HV) represent less than 1% of injuries in blunt abdominal trauma (BAT). When they do present, they are generally due to high-impact mechanisms in the segments of the intestine that are fixed. The aim of this study is to determine the incidence of major HV injuries in BAT at the "Dr. Domingo Luciani" General Hospital (HDL), and address the literature gap regarding updated HV perforations following BAT, especially in low-income settings. A retrospective review was conducted on the medical records of patients admitted to our trauma center with a diagnosis of complicated BAT with HV perforation over 14years. Seven hundred sixty-one patients were admitted under the diagnosis of BAT. Of them, 36.79% underwent emergency surgical resolution, and 6.04% had HV perforation as an operative finding. Almost half (44.44%) of these cases presented as a single isolated injury, while the remaining were associated with other intra-abdominal organ injuries. The most common lesions were Grade II-III jejunum and Grade I transverse colon, affecting an equal proportion of patients at 13.33%. In recent years, an increased incidence of HV injuries secondary to BAT has been observed. Despite this, in many cases, the diagnosis is delayed, so even in the presence of negative diagnostic studies, the surgical approach based on the trauma mechanism, hemodynamic status, and systematic reevaluation of the polytraumatized patient should prevail.

Characteristics and demography of low energy fall injuries in patients > 60 years of age: a population-based analysis over a decade with focus on undertriage

BackgroundAn increasing group of elderly patients is admitted after low energy falls. Several studies have shown that this patient group tends to be severely injured and is often undertriaged.MethodsPatients > 60 years with low energy fall (< 1 m) as mechanism of injury were identified from the Stavanger University Hospital trauma registry. The study period was between 01.01.11 and 31.12.20. Patient and injury variables as well as clinical outcome were described. Undertriage was defined as patients with a major trauma, i.e., Injury Severity Score (ISS) > 15, without trauma team activation. Statistical analysis was performed using the Chi-squared test for categorical variables and the Mann–Whitney U test for continuous variables.ResultsOver the 10-year study period, 388 patients > 60 years with low energy fall as mechanism of injury were identified. Median age was 78 years (IQR 68–86), and 53% were males. The location of major injury was head injury in 41% of the patients, lower extremities in 19%, and thoracic injuries in 10%. Thirty-day mortality was 13%. Fifty percent were discharged to home, 31% to nursing home, 9% in hospital mortality, and the remaining 10% were transferred to other hospitals or rehabilitation facilities. Ninety patients had major trauma, and the undertriage was 48% (95% confidence interval, 38 to 58%).ConclusionsPatients aged > 60 years with low energy falls are dominated by head injuries, and the 30-day mortality is 13%. Patients with major trauma are undertriaged in half the cases mandating increased awareness of this patient group.

Optimal Timing of Surgical Repair After Bile Duct Injury: A Systematic Review and Meta-Analysis.

Major bile duct injury during cholecystectomy often requires surgical reconstruction. The optimal timing of repair is debated. To assess the association between the timing of hepaticojejunostomy and postoperative morbidity, mortality, and anastomotic stricture. Systematic review and meta-analysis of observational studies comparing early (<14 days), intermediate (14 days-6 weeks), and late (>6 weeks) repair. Primary outcomes were postoperative morbidity, mortality, and stricture rates. Pooled risk ratios were calculated. A generalized linear model was used to estimate odds per time interval. 20 studies were included in the systematic review. Of these, data from 15 studies was included in the meta-analyses. The 20 included studies comprised a total of 3421 patients who underwent hepaticojejunostomy for bile duct injury. Early repair was associated with lower morbidity versus intermediate repair (RR 0.73, 95% CI 0.54-0.98). Delayed repair had lower morbidity versus intermediate (RR 1.50, 95% CI 1.16-1.93). Delayed repair had a lower stricture rate versus intermediate repair (RR 1.53, 95% CI 1.07-2.20). Mortality was not associated with timing. Reconstruction between 2 and 6 weeks after bile duct injury should be avoided given the higher morbidity and stricture rates. Delayed repair after 6 weeks may be beneficial.

Automated recognition of the major muscle injury in athletes on X-ray CT images1.

In this research, imaging techniques such as CT and X-ray are used to locate important muscles in the shoulders and legs. Athletes who participate in sports that require running, jumping, or throwing are more likely to get injuries such as sprains, strains, tendinitis, fractures, and dislocations. One proposed automated technique has the overarching goal of enhancing recognition. This study aims to determine how to recognize the major muscles in the shoulder and leg utilizing X-ray CT images as its primary diagnostic tool. Using a shape model, discovering landmarks, and generating a form model are the steps necessary to identify injuries in key shoulder and leg muscles. The method also involves identifying injuries in significant abdominal muscles. The use of adversarial deep learning, and more specifically Deep-Injury Region Identification, can improve the ability to identify damaged muscle in X-ray and CT images. Applying the proposed diagnostic model to 150 sets of CT images, the study results show that Jaccard similarity coefficient (JSC) rate for the procedure is 0.724, the repeatability is 0.678, and the accuracy is 94.9% respectively. The study results demonstrate feasibility of using adversarial deep learning and deep-injury region identification to automatically detect severe muscle injuries in the shoulder and leg, which can enhance the identification and diagnosis of injuries in athletes, especially for those who compete in sports that include running, jumping, and throwing.

Significance of Compensatory Jurisprudence Under The Employees Compensation Act, 1923

The basic rights contained in the Constitution of India would be useless unless and until concrete means to ensure them were implemented. There can be no justice if there is no remedy (Ubi jus ibi remedium). The term “compensation” refers to making amendments for a loss. Crime is more than simply a breach of the law; it also causes harm to victims and their families, including economic loss, emotional distress, and bodily, psychological, or intellectual injury. Crime has a wide variety of consequences for victims and their families, ranging from major injuries to minor disruptions. The concept of victims’ compensation is a well-established legal principle that is implemented within the framework of traditional civil courts. The court’s adoption of compensatory jurisprudence, guided by the principles of human rights philosophy, serves as a positive indication of its commitment to safeguarding the fundamental rights to life and personal liberty for all individuals, even in situations when there is a lack of explicit Constitutional provisions or established legal precedents. There is evidence that some groups of victims of crime were reimbursed, either by the perpetrator, their relatives, or the sovereign, even in ancient times. The right to compensate is a relatively new addition to Indian Constitutional law. This notion just began to gain traction in India under Constitutional law in the late 1980s. This was an innovative notion devised by the Indian Judiciary to ensure justice. Compensation is often granted based on the claimant’s entitlement. Modern justice is more concerned with delivering assistance to victims than with the requirements of legal principles. The right to compensation for violations of basic rights comes from the rights that were infringed, which shall be further addressed in the research.

Pathophysiology of Trauma-Induced Coagulopathy.

Trauma-induced coagulopathy (TIC) is a complex hemostatic disturbance that can develop early after a major injury. There is no universally accepted definition of TIC. However, TIC primarily refers to the inability to achieve sufficient hemostasis in severely injured trauma patients, resulting in diffuse microvascular and life-threatening bleeding. Endogenous TIC is driven by the combination of hypovolemic shock and substantial tissue injury, resulting in endothelial damage, glycocalyx shedding, upregulated fibrinolysis, fibrinogen depletion, altered thrombin generation, and platelet dysfunction. Exogenous factors such as hypothermia, acidosis, hypokalemia, and dilution due to crystalloid and colloid fluid administration can further exacerbate TIC. Established TIC upon emergency room admission is a prognostic indicator and is strongly associated with poor outcomes. It has been shown that patients with TIC are prone to higher bleeding tendencies, increased requirements for allogeneic blood transfusion, higher complication rates such as multi-organ failure, and an almost fourfold increase in mortality. Thus, early recognition and individualized treatment of TIC is a cornerstone of initial trauma care. However, patients who survive the initial insult switch from hypocoagulability to hypercoagulability, also termed "late TIC," with a high risk of developing thromboembolic complications.

Ticagrelor vs Clopidogrel for Complex Percutaneous Coronary Intervention in Chronic Coronary Syndrome

BackgroundWhether ticagrelor in chronic coronary syndrome patients undergoing complex percutaneous coronary intervention (PCI) can prevent cardiovascular events is unknown. ObjectivesThe authors sought to evaluate outcomes of complex PCI and the efficacy of ticagrelor vs clopidogrel in stable patients randomized in the ALPHEUS (Assessment of Loading with the P2Y12 inhibitor ticagrelor or clopidogrel to Halt ischemic Events in patients Undergoing elective coronary Stenting) trial. MethodsAll PCI procedures were blindly reviewed and classified as complex if they had at least 1 of the following criteria: stent length >60 mm, 2-stent bifurcation, left main, bypass graft, chronic total occlusion, use of atherectomy or guiding catheter extensions, multiwire technique, multiple stents. The primary endpoint was a composite of type 4a or b myocardial infarction (MI) and major myocardial injury during the 48 hours after PCI. We compared the event rates according to the presence or not of complex PCI criteria and evaluated the interaction with ticagrelor or clopidogrel. ResultsAmong the 1,866 patients randomized, 910 PCI (48.3%) were classified as complex PCI. The primary endpoint was more frequent in complex PCI (45.6% vs 26.6%; P < 0.001) driven by higher rates of type 4 MI and angiographic complications (12.2% vs 4.8 %; P < 0.001 and 19.3% vs 8.6%; P < 0.05, respectively). The composite of death, MI, and stroke at 48 hours (12.7% vs 5.1 %; P < 0.05) and at 30 days (13.4% vs 5.3%; P < 0.05) was more frequent in complex PCI. No interaction was found between PCI complexity and the randomized treatment for the primary endpoint (Pinteraction = 0.47) nor the secondary endpoints. ConclusionsIn chronic coronary syndrome, patients undergoing a complex PCI have higher rates of periprocedural and cardiovascular events that are not reduced by ticagrelor as compared with clopidogrel.

Abstract TP20: Microglial-Derived Extracellular Vesicles Protect From Neonatal Arterial Focal Stroke

Background: The developmental stage of the brain at the stroke onset plays a key role in the pathophysiology of injury, with neuroinflammation as a major injury modulator (Rayasam et al 2022; Hagberg et al. 2015). We reported that in the neonatal brain microglia secrete extracellular vesicles, exosomes and microvesicels, under physiological conditions and that microglial activation after transient MCA occlusion (tMCAO) in postnatal day 9 (P9) mice alters “cargo” of microglial-derived extracellular vesicles (MEV) and increases MEV uptake by microglia in vitro (Lecuyer et al., Neurobiol Dis. 2021). Here, we examined whether MEV administration protects the neonatal brain from stroke. Methods: P9 C57BL6 mice were subjected to a 3h tMCAO, microglia isolated from naïve mice and from injured (Inj) and contralateral (Contra) regions 24h after reperfusion using CD11b-conjugated beads, and cultured for 4 days in10% exosome-free FBS. MEV were purified from culture medium by multistep centrifugation [x300 g (Phase1, p1), x1,200 g (p2), x12,000 g (p3), and x100,000 g (p4)], concentration determined by Nanosight, MEV labelled with Claret-FR. MEV uptake by microglia from Inj and Contra regions was examined in vitro. 0.5 or 3.0 x 10 8 MEV were injected retro-orbital 2h after reperfusion. Behaviour outcomes (24h) and injury (at 4 days) were determined. Results: Post-vivo, uptake of p4C or p4I was increased by microglia from Inj, but not from Contra regions and reduced cell size and morphology within 30 min. Administration of p4-MEV from naïve (p4N-MEV), Contra (p4C-MEV) or Inj (p4I-MEV) regions significantly improved performance on Open Field test and reduced injury, whereas p3N-MEV did not affect inury. MEV increased survival (100%) compared to non-treated (77%) and vehicle-treated (83%) mice. We are defining p4 and p3 identity (exosomes Vs. microvesicles). Summary: p4-MEV but not p3-MEVprotect from neonatal stroke. Funding: R01 NS44025, R01 HL139685, R21 NS098514

Spinal Cord Tethering after Trauma and Impact of Age and Surgical Outcome

Introduction: Spinal cord tethering, a condition where the spinal cord becomes attached or fixed to surrounding tissues, can occur following trauma, leading to a range of neurological deficits and complications. Objectives: The main objective of the study is to find the spinal cord tethering after trauma and impact of age and surgical outcome in local population of Pakistan. Material and methods: This retrospective study was conducted in Ayub Medical Complex Abbottabad from January 2023 to August 2023. Data was collected from 50 patients of spinal cord tethering patients. Data collection involved a comprehensive review of the medical records of patients. Relevant demographic information, including age at the time of trauma, gender, and comorbidities, was extracted. Clinical details such as mechanism of injury, level and severity of spinal cord injury, duration of symptoms and preoperative neurological status were documented. Results: Data were collected from 50 SCI patients. The mean age of the patients was 45 ± 10.5 years and there were 60% male and 40% female patients. The most common mechanisms of injury were motor vehicle accidents (50%), followed by falls (30%) and sports-related injuries (20%). Regarding the spinal level affected, the majority of injuries were cervical (60%), followed by thoracic (30%) and lumbar (10%). Neurological improvement was observed in 40% of patients, with complete improvement in 40% and partial improvement in 20%, while 40% showed no improvement. Complications were reported in a subset of patients, with cerebrospinal fluid leaks occurring in 15%, wound infections in 10%, and other complications in 5% of cases. Reoperation was necessary in 10% of patients, while 90% did not require further surgical intervention. Age and neurological improvement showed non-significant differences between groups (p &gt; 0.05), while length of hospital stay differed significantly (p = 0.018). Complications and functional improvement did not vary significantly between groups (p &gt; 0.05) Practical Implication: This study's practical implications offer vital benefits to the community. The identification of age as a critical component in spinal cord tethering after trauma enables healthcare practitioners to more accurately evaluate risk and customize therapies. Furthermore, our research emphasizes how successful surgical therapies are for patients of all ages, giving patients confidence in their available treatment alternatives. Further improving patient care is pushing for individualized treatment options and being aware of related consequences. Conclusion: It is concluded that age influences the occurrence of spinal cord tethering following trauma, with older patients being more susceptible to this complication. However, surgical intervention appears to be equally effective across age groups, with comparable rates of neurological improvement and complications.

Long-term outcomes of autologous vein bypass for repair of upper and lower extremity major arterial trauma

ObjectiveAutologous vein is the preferred bypass conduit for extremity arterial injuries owing to superior patency and low infection risk; however, long-term data on outcomes in civilians are limited. Our goal was to assess short- and long-term outcomes of autologous vein bypass for upper and lower extremity arterial trauma. MethodsA retrospective review was performed of patients with major extremity arterial injuries (2001-2019) at a level I trauma center. Demographics, injury and intervention details, and outcomes were recorded. Primary outcomes were primary patency at 1 year and 3 years. Secondary outcomes were limb function at 6 months, major amputation, and mortality. Multivariable analysis determined risk factors for functional impairment. ResultsThere were 107 extremity arterial injuries (31.8% upper and 68.2% lower) treated with autologous vein bypass. Mechanism was penetrating in 77% of cases, of which 79.3% were due to firearms. The most frequently injured vessels were the common and superficial femoral (38%), popliteal (30%), and brachial arteries (29%). For upper extremity trauma, concomitant nerve and orthopedic injuries were found in 15 (44.1%) and 11 (32.4%) cases, respectively. For lower extremities, concomitant nerve injuries were found in 10 (13.7%) cases, and orthopedic injuries in 31 (42.5%). Great saphenous vein was the conduit in 96% of cases. Immediate intraoperative bypass revision occurred in 9.3% of patients, most commonly for graft thrombosis. The in-hospital return to operating room rate was 15.9%, with graft thrombosis (47.1%) and wound infections (23.5%) being the most common reasons. The median follow-up was 3.6 years. Kaplan-Meier analysis showed 92% primary patency at 1 year and 90% at 3 years. At 6 months, 36.1% of patients had functional impairment. Of patients with functional impairment at 6 months, 62.9% had concomitant nerve and 60% concomitant orthopedic injuries. Of those with nerve injury, 91.7% had functional impairment, compared with 17.8% without nerve injury (P < .001). Of patients with orthopedic injuries, 51.2% had functional impairment, vs 25% of those without orthopedic injuries (P = .01). On multivariable analysis, concomitant nerve injury (odds ratio, 127.4; 95% confidence interval, 17-957; P <. 001) and immediate intraoperative revision (odds ratio, 11.03; 95% confidence interval, 1.27-95.55; P = .029) were associated with functional impairment. ConclusionsAutologous vein bypass for major extremity arterial trauma is durable; however, many patients have long-term limb dysfunction associated with concomitant nerve injury and immediate intraoperative bypass revision. These factors may allow clinicians to identify patients at higher risk for functional impairment, to outline patient expectations and direct rehabilitation efforts toward improving functional outcomes.

Caregiver reported long-term outcomes in children with major trauma and traumatic brain injuries: A single-centre retrospective study.

We aim to investigate the functional outcomes and long-term health-related quality of life (HRQOL) in children with major trauma associated with traumatic brain injury (TBI). We performed a retrospective review of records among patients >2 and ≤16 years old in a tertiary paediatric hospital between January 2014 and October 2019 with major trauma (Injury Severity Score of ≥16) and TBI of all severities. We recorded each child's Glasgow Outcome Scale-Extended Pediatric Version (GOS-E Peds) at 12 months post-injury and Pediatric Quality of Life Inventory (PedsQL) scores at 6 and 12 months post-injury based on the parent proxy-report scales. We included 53 patients with a median age of 9.0 years old (interquartile range 2.3-15.5). Most injuries were due to falls (30, 56.6%) or road traffic collisions (15, 28.3%); 41 patients (77.3%) required intensive care while 30 patients (56.6%) underwent neurosurgical intervention. Most patients (43, 81.1%) had GOS-E Peds scores of ≤2 at 12 months post-injury. We reported a significant mean difference between the 6- and 12-month parent-reported scores for physical functioning (6.6, 95% confidence interval [CI] 0.3-12.8, P=0.041), psychosocial functioning (4.1, 95% CI 1.0-7.2, P=0.012) and overall scores (5.0, 95% CI 1.4-8.7, P=0.008). Compared with the validated PedsQL scores, our mean scores were higher across all domains at 12 months. With current standard of care, parents of children with major trauma and TBI reported gains in quality of life, physical, psychosocial and overall function between 6 and 12 months post-injury.

Shoulder injuries in Brazilian professional football players: epidemiological analysis of 3828 games

ObjectivesFootball is a globally played sport that poses potential risks for musculoskeletal injuries. Upper-limb injuries have a lower incidence rate than lower-limb injuries but can still cause absenteeism and performance impairment in football players. This descriptive epidemiological study aimed to evaluate and compare the epidemiological data on shoulder injuries among professional football players in two major Brazilian football championships. MethodsData were collected throughout the championships, and club physicians medically evaluated each player during official games using two online forms. The collected information included the player's age and position, injury diagnosis, laterality, location on the field where the injury occurred, playing time, imaging examinations performed, need for surgical treatment, time to return to play (TRP), and recurrence of the injury. The incidence of injuries was evaluated using the Federation Internationale de Football Association (FIFA) incidence formula. ResultsA total of 107 shoulder injuries were recorded (4.3% of all injuries), with a FIFA incidence of 0.847. Glenohumeral dislocations (GHDs) and acromioclavicular dislocations (ACDs) accounted for 37.38% and 35.51% of all shoulder injuries, respectively. Goalkeepers and defenders presented, respectively, a 2.15 and 1.57 times increased risk of suffering shoulder injuries, while attackers presented a 0.63 times decreased risk. Injury recurrence was observed in 14.95% of cases, with GHDs and ACDs showing recurrence rates of 35.00% and 5.26%, respectively. Surgery was performed in 9.35% of cases, with GHDs representing 50% of all surgeries. The average TRP was 22.37 days, with severe and major injuries accounting for 11.21% and 10.28% of all injuries, respectively. Goalkeepers had the highest average TRP of 36.15 days. Recurring injuries had a higher average TRP of 33.44 days compared to nonrecurring injuries, which had an average TRP of 20.43 days. Surgically treated injuries had the highest average TRP of 112.5 days. ConclusionShoulder injuries in the professional football scenario are of great concern due to the high recurrence rate and need for surgical treatment, which will lead to a long TRP. These findings emphasize the need to implement prevention protocols and effective treatments to reduce the consequences of such injuries, which are usually underestimated in this sport.
