Characteristics of pediatric mandibular condylar fractures in Southwest China: A single-center and 12-year retrospective study.

BACKGROUND/AIM: Mandibular condylar fractures in pediatric patients may exhibit distinct epidemiological characteristics attributed to their unique growth and development phase, as well as various anatomical, physiological, biomechanical, and behavioral factors that differentiate them from adults. This study aimed to investigate the demographics, injurious factors, classifications, clinical manifestations, and treatments of pediatric mandibular condylar fractures, as well as the concomitant injuries in maxillofacial and other body parts. MATERIALS AND METHODS: This retrospective study analyzed the clinical data of 189 pediatric patients with mandibular condylar fractures between 2011 and 2022. Variables investigated included age, gender, timing of onset, causes, classification of condylar fracture, concomitant injuries, clinical manifestations, and treatment modalities. RESULTS: A total of 189 patients, a higher proportion of boys compared to girls was observed, with the highest incidence rate in children aged 1-3 years. They occurred primarily in July, June, and September as well as on Saturdays and Sundays. The most prevalent cause of mandibular condylar fractures was falls from heights in 73 patients (38.62%). Pediatric patients exhibited a higher susceptibility to condylar head fractures. A significant majority (81.48%) of these fractures were accompanied by soft tissue injuries in the maxillofacial region, with the chin being particularly vulnerable to injury. In addition, 61.90% of pediatric patients experienced fractures in other areas of the maxillofacial region, with the mandibular symphysis being the most commonly affected site. Dental trauma predominantly occurred in the anterior region (44.97%). Notably, a substantial proportion (28.04%) of cases also presented with multiple systemic injuries. CONCLUSIONS: The characteristics of pediatric mandibular condylar fractures exhibit distinct features in terms of age, gender, timing of onset, etiology, location and type, the presence of concomitant maxillofacial soft/hard tissue injuries and multiple systemic injuries, as well as clinical manifestations and treatment modalities. Therefore, clinicians should pay special attention to the diagnosis and treatment of pediatric condylar fractures.

Timing of Spinal Surgery in Polytrauma: The Relevance of Injury Severity, Injury Level and Associated Injuries.

STUDY DESIGN: Retrospective database analysis. OBJECTIVE: Polytraumatized patients with spinal injuries require tailor-made treatment plans. Severity of both spinal and concomitant injuries determine timing of spinal surgery. Aim of this study was to evaluate the role of spinal injury localization, severity and concurrent injury patterns on timing of surgery and subsequent outcome. METHODS: The TraumaRegister DGU® was utilized and patients, aged ≥16 years, with an Injury Severity Score (ISS) ≥16 and diagnosed with relevant spinal injuries (abbreviated injury scale, AIS ≥ 3) were selected. Concurrent spinal and non-spinal injuries were analysed and the relation between injury severity, concurrent injury patterns and timing of spinal surgery was determined. RESULTS: 12.596 patients with a mean age of 50.8 years were included. 7.2% of patients had relevant multisegmental spinal injuries. Furthermore, 50% of patients with spine injuries AIS ≥3 had a more severe non-spinal injury to another body part. ICU and hospital stay were superior in patients treated within 48 hrs for lumbar and thoracic spinal injuries. In cervical injuries early intervention (<48 hrs) was associated with increased mortality rates (9.7 vs 6.3%). CONCLUSIONS: The current multicentre study demonstrates that polytrauma patients frequently sustain multiple spinal injuries, and those with an index spine injury may therefore benefit from standardized whole-spine imaging. Moreover, timing of surgical spinal surgery and outcome appear to depend on the severity of concomitant injuries and spinal injury localization. Future prospective studies are needed to identify trauma characteristics that are associated with improved outcome upon early or late spinal surgery.

Concomitant Injuries Associated With ACL Rupture in Elite Professional Alpine Ski Racers and Soccer Players: A Comparative Study With Propensity Score Matching Analysis.

Background: For elite professional soccer players and alpine skiers, injuries associated with anterior cruciate ligament (ACL) rupture, such as meniscal, cartilage, or collateral ligament lesions, could result in a delayed return to sport compared with isolated ACL injury. Purpose/Hypothesis: The purpose of the study was to provide a detailed description of associated injuries at the time of primary ACL reconstruction in elite soccer players and alpine skiers. It was hypothesized that soccer players and skiers would present different typical injury patterns due to different injury mechanisms. Study Design: Cohort study; Level of evidence, 3. Methods: Surgical reports and arthroscopic images of elite professional soccer players and alpine skiers who underwent primary ACL reconstruction at a single institution between January 2010 and June 2022 were analyzed retrospectively. The presence and location of multiligamentous injury, meniscal tears, and chondral lesions were compared between the athlete groups. A propensity score matching analysis with 1:1 ratio was performed between skiers and soccer players to limit the effect of selection bias. Results: Included were ACL reconstruction data representative of 37 soccer players and 44 alpine skiers. Meniscal pathology was found in 32 (86%) soccer players and 30 (68%) skiers. Chondral injuries were reported in 11 (30%) soccer players and 15 (34%) skiers. Results of the propensity score matching analysis in 15 pairs of soccer players and skiers indicated that soccer players had a significantly higher rate of medial meniscal injuries (73% vs 27%; P = .03) and lateral posterior root tears (33% vs 0%; P = .04) compared with skiers. Conclusion: A higher prevalence of combined chondral and meniscal injuries versus isolated ACL injuries was observed in both groups of athletes. Professional soccer players were characterized by higher prevalence of medial meniscal tears and lateral posterior root lesions compared with professional alpine skiers.

[Treatment of pancreatic injuries after blunt abdominal trauma]. / Behandlung von Pankreasverletzungen nach stumpfem Bauchtrauma.

Pancreatic injuries resulting from blunt abdominal trauma are uncommon but carry a high risk of morbidity and mortality for patients. Prompt diagnosis and management are critical to optimize patient outcomes. This review article provides an overview of the different types of pancreatic injuries and the various management strategies available, based on the severity of the injury. In unstable patients with a positive focused assessment with sonography for trauma (FAST), immediate trauma laparotomy is required. Stable patients should be assessed with contrast-enhanced computed tomography (CT) imaging. Low-grade injuries can be managed with irrigation and drainage. In cases of left-sided ductal injury below the level of the portal vein, left-sided pancreatic resection is often necessary. Higher grade injuries to the pancreatic head need to be evaluated in the context of other accompanying injuries, where damage control may be required. Pancreaticoduodenectomy is a rare intervention and is usually only required in the later course in these cases.

Insurance cost and injury characteristics of anterior cruciate ligament injuries in sub-elite football: A population analysis involving 3 years of Australian insurance data.

OBJECTIVES: To investigate the injury characteristics and insurance cost of anterior cruciate ligament injuries in sub-elite football players in New South Wales, Australia. DESIGN: Descriptive epidemiological study. METHODS: Three years of insurance records (2018-2020) was used to describe anterior cruciate ligament injury costs and characteristics. Concomitant injuries and the mechanism of injury were determined by analysing the injury descriptions. Claim characteristics and costs are presented by age group (junior = 7-17 years, senior = 18-34 years, and veteran = 35 + years) and sex. Categorical data (including age-groups and sex) are presented as counts and percentages and analysed using a Chi squared or Fisher's exact test. Cost data are reported as means ±â€¯standard deviation with 95 % confidence intervals. RESULTS: Over the course of three football seasons (2018-2020), 786 anterior cruciate ligament injuries were reported to the injury insurance company. The total insurance cost was AU$3,614,742 with direct injury insurance costs accounting for 36.3 % of the total costs. The mean indirect insurance costs were six-fold higher than direct insurance costs (AU$11,458 vs AU$1914). Isolated injuries had an average cost of $4466 whilst concomitant injuries had an average cost of $4951. Surgical costs are excluded from direct cost calculations. The peak injury count occurred in the first month of all three football seasons, immediately after the pre-season. CONCLUSIONS: Anterior cruciate ligament injuries represent a substantial economic burden to the insurer and individual. The cost data provided can be used for future economic and modelling studies.

Inter-facility transfers for burn patients with concomitant traumatic injuries.

Burn patients with concomitant traumatic injuries suffer increased morbidity and mortality. Complex care coordination is necessary for these patients, and the prevalence of resulting inter-facility transfers has not yet been quantified by literature. This study examined the outcomes for traumatically injured burn patients to identify the occurrence of trauma system transfers in this group. The National Trauma Data Bank was reviewed from the years 2007-2016 for 6,565,577 patients with traumatic, burn, and concomitant burn & traumatic injuries. There were 5068 patients with both traumatic and burn injuries, 145,890 patients with burn injuries, and 6,414,619 patients with traumatic injuries. Trauma/burn patients were more often admitted to the ICU from the ED at a rate of 35.5% compared to 27.1% for burn and 19.4% for trauma (P < 0.001). For disposition when discharged from the hospital, trauma/burn patients required more inter-facility transfers at a rate of 2.5% compared to 1.7% for burn and 1.3% for trauma (P < 0.001). For level I trauma centers, 5.5% of trauma/burn, 7.1% of burn, and 0.5% of trauma patients required inter-facility transfers. For level II trauma centers, 29.1% of trauma/burn, 47.0% of burn, and 2.8% of trauma patients required inter-facility transfers. Among level I and level II trauma centers, patients with only burns and burn patients with concomitant traumatic injuries required more inter-facility transfers, and level II trauma centers required more inter-facility transfers for all patients. Quantifying these findings is the first step toward improving triage decisions and allocation of health care resources while expediting appropriate care.

Surgeon's experience, sports participation and a concomitant MCL injury increase the use of patellar and quadriceps tendon grafts in primary ACL reconstruction: a nationwide registry study of 39,964 surgeries.

PURPOSE: To investigate the influence of surgeon-related factors and clinic routines on autograft choice in primary anterior cruciate ligament reconstruction (ACLR). METHODS: Data from the Swedish National Knee Ligament Registry (SNKLR), 2008-2019, were used to study autograft choice (hamstring; HT, patellar; PT, or quadriceps tendon; QT) in primary ACLR. Patient/injury characteristics (sex, age at surgery, activity at time of injury and associated injuries) and surgeon-/clinic-related factors (operating volume, caseload and graft type use) were analyzed. Surgeon/clinic volume was divided into tertiles (low-, mid- and high-volume categories). Multivariable logistic regression was performed to assess variables influencing autograft choice in 2015-2019, presented as the odds ratio (OR) with a 95% confidence interval (CI). RESULTS: 39,964 primary ACLRs performed by 299 knee surgeons in 91 clinics were included. Most patients received HT (93.7%), followed by PT (4.2%) and QT (2.1%) grafts. Patients were mostly operated on by high-volume (> 28 ACLRs/year) surgeons (68.1%), surgeons with a caseload of ≥ 50 ACLRs (85.1%) and surgeons with the ability to use ≥ two autograft types (85.9%) (all p < 0.001). Most patients underwent ACLR at high-volume (> 55 ACLRs/year) clinics (72.2%) and at clinics capable of using ≥ two autograft types (93.1%) (both p < 0.001). Significantly increased odds of receiving PT/QT autografts were found for ACLR by surgeons with a caseload of ≥ 50 ACLRs (OR 1.41, 95% CI 1.11-1.79), but also for injury during handball (OR 1.31, 95% CI 1.02-1.67), various other pivoting sports (basketball, hockey, rugby and American football) (OR 1.59, 95% CI 1.24-2.03) and a concomitant medial collateral ligament (MCL) injury (OR 4.93, 95% CI 4.18-5.80). In contrast, female sex (OR 0.87, 95% CI 0.77-0.97), injury during floorball (OR 0.71, 95% CI 0.55-0.91) and ACLR by mid-volume relative to high-volume surgeons (OR 0.62, 95% CI 0.53-0.73) had significantly reduced odds of receiving PT/QT autografts. CONCLUSION: An HT autograft was used in the vast majority of cases, but PT/QT autografts were used more frequently by experienced surgeons. Prior research has demonstrated significant differences in autograft characteristics. For this reason, patients might benefit if surgery is performed by more experienced surgeons. LEVEL OF EVIDENCE: Level III.

Clinical Effectiveness of Arthroscopy-Assisted Fixation in the Treatment of Avulsed Posterior Cruciate Ligament Injuries.

Avulsed posterior cruciate ligament (PCL) injuries are complex orthopedic challenges that require careful consideration and optimal management. Arthroscopy offers advantages, including smaller incisions, reduced soft tissue disruption, reduced postoperative pain, and improved visualization of intraarticular anatomy. Arthroscopy-assisted fixation results in superior clinical outcomes. Patient-specific factors, graft choice, and timing of surgery significantly impact outcomes. Rehabilitation is vital and requires a tailored approach to restore knee function. Biomechanically, arthroscopy-assisted fixation enhances joint stability and range of motion, reducing the risk of secondary injuries. Advancements in technology and surgical techniques further improve outcomes. Concomitant injuries and incorporation are essential considerations. Arthroscopy-assisted fixation is a recommended approach, but personalized care is crucial for successful recovery. Its precision in reattaching the PCL enhances joint stability and clinical results, aligning with outcomes seen in conventional procedures. Using biocompatible materials in fixation devices has significantly reduced the risk of allergic reactions or complications. This has allowed a faster and smoother recovery process for patients undergoing arthroscopy-assisted fixation. The incorporation of physical therapy and rehabilitation programs after surgery plays a vital role in restoring joint function and preventing muscle atrophy. The combination of advanced technology, surgical techniques, and personalized care has greatly improved the success rate of arthroscopy-assisted fixation procedures. Advancements in technology further improve patient outcomes, but each case should be individually assessed to determine the most appropriate treatment approach.

A systematic review of outcome reporting in clinical trials of distal tibia and ankle fractures : the need for a core outcome set.

AIMS: To describe outcome reporting variation and trends in non-pharmacological randomized clinical trials (RCTs) of distal tibia and/or ankle fractures. METHODS: Five electronic databases and three clinical trial registries were searched (January 2000 to February 2022). Trials including patients with distal tibia and/or ankle fractures without concomitant injuries were included. One reviewer conducted all searches, screened titles and abstracts, assessed eligibility, and completed data extraction; a random 10% subset were independently assessed and extracted by a second reviewer at each stage. All extracted outcomes were mapped to a modified version of the International Classification of Functioning, Disability and Health framework. The quality of outcome reporting (reproducibility) was assessed. RESULTS: Overall, 105 trials (n = 16 to 669 participants) from 27 countries were included. Trials compared surgical interventions (n = 62), post-surgical management options (n = 17), rehabilitative interventions (n = 14), surgical versus non-surgical interventions (n = 6), and pre-surgical management strategies (n = 5). In total, 888 outcome assessments were reported across seven domains: 263 assessed body structure or function (85.7% of trials), 136 activities (68.6% of trials), 34 participation (23.8% of trials), 159 health-related quality of life (61.9% of trials), 247 processes of care (80% of trials), 21 patient experiences (15.2% of trials), and 28 economic impact (8.6% of trials). From these, 337 discrete outcomes were described. Outcome reporting was inconsistent across trials. The quality of reporting varied widely (reproducibility ranged 4.8% patient experience to 100% complications). CONCLUSION: Substantial heterogeneity in outcome selection, assessment methods, and reporting quality were described. Despite the large number of outcomes, few are reported across multiple trials. Most outcomes are clinically focused, with little attention to the long-term consequences important to patients. Poor reporting quality reduces confidence in data quality, inhibiting data synthesis by which to inform care decisions. Outcome reporting guidance and standardization, which captures the outcomes that matter to multiple stakeholders, are urgently required.Cite this article: Bone Jt Open 2022;3(10):832-840.

Surgical fixation of rib fractures improves 30-day survival after significant chest injury : an analysis of ten years of prospective registry data from England and Wales.

AIMS: The last decade has seen a marked increase in surgical rib fracture fixation (SRF). The evidence to support this comes largely from retrospective cohorts, and adjusting for the effect of other injuries sustained at the same time is challenging. This study aims to assess the impact of SRF after blunt chest trauma using national prospective registry data, while controlling for other comorbidities and injuries. METHODS: A ten-year extract from the Trauma Audit and Research Network formed the study sample. Patients who underwent SRF were compared with those who received supportive care alone. The analysis was performed first for the entire eligible cohort, and then for patients with a serious (thoracic Abbreviated Injury Scale (AIS) ≥ 3) or minor (thoracic AIS < 3) chest injury without significant polytrauma. Multivariable logistic regression was performed to identify predictors of mortality. Kaplan-Meier estimators and multivariable Cox regression were performed to adjust for the effects of concomitant injuries and other comorbidities. Outcomes assessed were 30-day mortality, length of stay (LoS), and need for tracheostomy. RESULTS: A total of 86,838 cases were analyzed. The rate of SRF was 1.2%. SRF significantly reduced risk of mortality (odds ratio (OR) 0.27 (95 confidence interval (CI) 0.128 to 0.273); p < 0.001) and need for tracheostomy (OR 0.22 (95% CI 0.191 to 0.319); p < 0.001) after adjustment for other covariables across the whole cohort. SRF remained protective in patients with a serious chest injury (hazard ratio (HR) 0.24 (95% CI 0.13 to 0.45); p < 0.001). The benefit in more minor chest injury was less clear. Mean LoS for patients who survived was longer in the SRF group (24.29 days (SD 26.54) vs 16.60 days (SD 26.35); p < 0.001). CONCLUSION: SRF reduces mortality after significant chest trauma associated with both major and minor polytrauma. The rate of fixation in the UK is low and potentially underused as a treatment for severe chest wall injury. Cite this article: Bone Joint J 2022;104-B(6):729-735.

Patterns of concomitant injury in thoracic spine fractures.

Background: Thoracic spine fractures (TSFs) are rarely isolated injuries, and they tend to present with a characteristic set of vertebral and non-vertebral injuries based on mechanism of injury. There is limited research on the rates and distribution of injuries that occur concurrently with TSFs. The purpose of this study is to characterize the distributions of these injuries by region of the body and by mechanisms of injury, so that trauma and spine surgeons can efficiently evaluate and treat patients presenting with TSFs. Methods: We retrospectively reviewed the trauma database records of 683 patients presenting with a TSFs at a single institution from 2015 to 2019. We recorded patient demographics, comorbidities, and associated injuries by body region. We characterized the TSFs using the AO classification system, as well as the presenting physical exam and treatment. All associated injuries among the TSF patients were classified into the following categories: head injury (HI), thoracic injury (TI), non-thoracic vertebral injury (NTVI), abdominal injury (AI), upper extremity injury (UEI), lower extremity injury (LEI), and spinal cord injury (SCI). Results: The three leading causes of TSFs were mechanical falls (38.4%), falls from height (24.9%), and motor vehicle crashes (MVCs) (23.4%). Patients with a TSF from MVC were statistically more likely to have concomitant injuries of TI, NTVI, AI, HI, UEI, and LEI. TSFs from fall from height were statistically more likely to have TI, NTVI, and LEI. TSFs from mechanical falls had significantly lower rates of all injury locations, but still presented with high rates of additional injury. TSFs from motorcycle crashes (MCCs) presented with TI, AI, UEI, and LEI. There were high rates of treatment for TSFs, with surgery ranging from 5.3% to 20.0% and bracing from 52.3% to 65.7% depending on mechanism of injury. Conclusions: TSFs after MVCs, mechanical falls, falls from height, and MCCs presented with a predictable pattern of injuries and were rarely an isolated injury. This cross-sectional data may help spine and trauma surgeons better understand patterns of injury associated with TSFs, with the hope of preventing missed injuries and better advising patients with TSFs on severity of injuries.

Influence of concomitant injuries on post-concussion symptoms after a mild traumatic brain injury - a prospective multicentre cohort study.

Objectives: To compare post-concussion symptoms (PCS) and return to normal activities between mild Traumatic Brain Injury (mTBI) patients with or without concomitant injuries at 7-and 90 days post-mTBI.Methods: Design: Sub-analysis of a multicentre prospective cohort study. PARTICIPANTS AND SETTING: patients with mTBI from 7 Canadian Emergency Departments. PROCEDURE: Research assistants conducted telephone follow-ups using the Rivermead Postconcussion Symptoms Questionnaire (RPQ) at 7-, 30- and 90 days post-mTBI. MAIN OUTCOME: Presence of PCS (RPQ: ≥3 symptoms) at 90 days. SECONDARY OUTCOMES: RPQ score ≥21, prevalence of individual RPQ symptoms and patients' return to normal activities, at 7- and 90-days. Adjusted risk ratios (RR) were calculated.Results: 1725 mTBI patients were included and 1055 (61.1%) had concomitant injuries. Patients with concomitant injuries were at higher risk of having ≥3 symptoms on the RPQ (RR:1.26 [95% CI 1.01-1.58]) at 90 days. They were also at higher risk of experiencing specific symptoms (dizziness, fatigue, headaches and taking longer to think) and of non-return to their normal activities (RR:2.11 [95% CI 1.30-3.45]).Conclusion: Patients with concomitant injuries have slightly more PCS and seemed to be at higher risk of non-return to their normal activities 90 days, compared to patients without concomitant injuries.

Comparing Outcomes between Arthroscopic-Assisted Reduction and Fluoroscopic Reduction in AO Type C Distal Radius Fracture Treatment.

Background Distal radius fracture is one of the most common injuries. Poor functional result with restricted wrist motion can be developed when there is intra-articular fibrous tissue development arising from articular step-off and gapping. Objectives The aim of this study is to compare the functional and radiological outcome between arthroscopic-assisted reduction and fluoroscopic reduction in treating unstable intra-articular distal radius fracture. Methods We retrospectively analyzed 12 patients with intraarticular AO type C distal radius fracture treated with arthroscopic-assisted fracture reduction and internal fixation and compared them with another group of 12 patients in which fracture reduction is assessed by fluoroscopy alone (15 males and 9 females, mean age 57.3, range 27-73). The two cohorts were analyzed for differences in radiological parameters including articular stepping and gapping, palmar tilt, radial inclination, ulnar variance as well as functional outcome in range of motion, grip strength, modified mayo wrist score, and Quick Disabilities of the Arm, Shoulder, and Hand (DASH) score at an average of 12.5 months (range 5-26) after surgery. Results Arthroscopic-assisted fracture reduction group has statistically better restoration of articular stepping and gapping, volar tilt and ulnar variance. Range of motion, grip strength, modified mayo wrist score and Quick DASH score also had statistically significant improvement in arthroscopic group. Conclusion Our study showed arthroscopic-assisted technique can precisely restore radiological parameters in highly comminuted distal radius fracture with good functional outcome. Also, associated intra-articular soft tissue injury can be detected and treated simultaneously. Level of Evidence This is a level III, retrospective cohort study.

In recreational alpine skiing, the ACL is predominantly injured in all knee injuries needing hospitalisation.

PURPOSE: The knee joint still represents the most frequent anatomical injury location accounting for about one-third of all injuries in recreational alpine skiers. However, comprehensive information on current knee injury patterns in this populations is sparse. METHODS: During the winter seasons 2016/17 and 2019/20, this retrospective questionnaire-based study was conducted in an Austrian sportclinic situated in a large ski area. Among a cohort of 282 recreational skiers (51.8% females), all injuries were diagnosed by the use of magnetic resonance imaging. Additionally, data were recorded on anthropometric characteristics, the perceived speed at the moment of injury, type of fall, physical fitness, self-reported skill level and risk-taking behaviour. RESULTS: The anterior cruciate ligament (ACL) was injured in all knee injuries recorded. Of the total study sample, 64.5% (n = 182) were ACL injuries with concomitant injuries and about 35.5% (n = 100) were isolated ACL injuries, not involving any other structures of the knee joint. In general, most common concomitant injury diagnoses among ACL-injured recreational alpine skiers were injuries of the medial collateral ligament (MCL) (n = 92, 50.5%), medial meniscus (MM) (n = 73, 40.1%) and lateral collateral ligament (LCL) (n = 41, 22.5%). No significant differences regarding additionally recorded characteristics were found between ACL-injured individuals with concomitant injuries and those with isolated ACL injury. CONCLUSIONS: Whereas, before the introduction of carving skis, the MCL was reported being the most common injured part of the knee, currently, the majority of knee injuries are ACL injuries accompanied by injury of other knee joint structures, i.e. the MCL, MM and LCL. LEVEL OF EVIDENCE: Level III.

Injuries of the sternoclavicular region indicate concomitant lesions and need distinguished imaging.

PURPOSE: To evaluate injuries of the sternoclavicular region as indicator injury for relevant concomitant injuries and to evaluate the modalities of initial imaging. We hypothesised a high incidence of concomitant injuries as well as a deficiency of X-ray as the initial gold standard. METHODS: We retrospectively analysed patients suffering from injuries of the sternoclavicular region between 2002 and 2017. We analysed amongst injury type and severity, initial imaging (X-ray vs. CT scan of the sternoclavicular region vs. whole-body scan), and complement of imaging with regard to defined concomitant injury localisations and the resulting necessity and urgency of surgery. RESULTS: We included n = 61 patients. The mean ISS was 13.5 ± 17, n = 13 (21.3%) cases were classified as "severely injured" (ISS ≥ 16). N = 29 (47.5%) achieved an initial X-ray, n = 10 (16.4%) an initial CT scan of the sternoclavicular region, and n = 22 (36%) an initial whole-body CT scan. Initial imaging correlated significantly with ISS. In n = 21 (72.4%) cases of the X-ray group a significant complement from X-ray to CT scan of the sternoclavicular region was indicated (p ≤ 0.001). N = 31 (50.8%) patients suffered from concomitant injuries. N = 39 (63.9%) of all patients underwent any kind of surgery, thereof n = 23 (37.7%) related to their sternoclavicular injuries. CONCLUSION: Injuries of the sternoclavicular complex are indicators for the presence of multiple injuries. A CT scan of the sternoclavicular region including ipsilateral apex of the lung and upper rib cage comprised a large proportion of concomitant injuries. Mapping those injuries during initial imaging improves treatment process, avoids underdiagnostic, and decreases uncertainties.

Arthroscopic assisted treatment of distal radius fractures and concomitant injuries.

Wrist arthroscopy is mainly used to assist fracture reduction and fixation and to diagnose and treat concomitant injuries mainly to the scapholunate (SL), lunotriquetral (LT) ligament and the triangular fibrocartilage complex (TFCC). Arthroscopy is beneficial in improving anatomical reduction of fracture steps and gaps in intra-articular distal radius fractures (DRFs). Yet, the literature that the functional outcome correlates with the use of arthroscopy, is limited. Non-surgical treatment and immobilization is recommended for Geissler grade I-III Sl-ligament injuries, while open reduction, ligament suture and/or K-wire pinning is mandatory for complete ligament tears according to Geissler grade IV. This manuscript describes the current literature and gives insight into the authors' opinions and practice.

Comparison between traumatic brain injury with and without concomitant injuries: an analysis based on a national trauma registry 2008-2016.

Objective: To compare demographic, injury and hospitalization characteristics and mortality between Isolated and Non-Isolated traumatic brain injury.Methods: A retrospective study based on the Israeli National Trauma Registry of patients hospitalized for traumatic brain injury (TBI) between 2008 and 2016. Isolated TBI was defined as no other anatomic region was having concomitant injury with AIS ≥2. X2 test and multivariate logistic regression analysis were used for data analysis.Results: Of the 23566-study population, 40.4% were admitted for isolated TBI. Isolated TBI was significantly more frequent in elderly aged ≥65 years, female, Jews, and injuries sustained at home or in residential institution. The Non-isolated TBI was greater in road traffic injuries, particularly among pedestrians and motor cyclists, and in violence injuries. The Non-isolated TBI group had greater injury severity and hospital resource utilization. In-hospital mortality was higher in the patients with Non-isolated TBI [OR: 1.56(95% CI: 1.33-1.83)], particularly in patients with GCS 13-15; elderly aged 65+ years; and patients with concomitant injuries to abdomen, spine or external body regions.Conclusion: In a patient with TBI, concomitant injuries with AIS ≥2 matter, and awareness of the identified factors has relevance for guiding injury prevention efforts and indeed for potentially improving care and outcome.

Prevalence and Etiology of Pediatric Maxillofacial Injuries: A Unicenter-based Retrospective Study.

BACKGROUND: Children are uniquely susceptible to craniofacial trauma because of their greater cranial mass-to-body ratio. The craniofacial injuries comprise approximately 11.3% of an overall pediatric emergency, and its etiology affects the incidence, clinical presentation, and treatment modalities, which are influenced by sociodemographic, economic, and cultural factor of the population being studied. MATERIALS AND METHODS: A retrospective review to analyze the epidemiology of facial injuries in pediatric population (age range-0-16 years), divided into three age groups, i.e., group I (0-5 years), group II (6-11 years) and group III (12-16 years), was carried out over a 3-year span, in order to determine the facial injury pattern, mechanism and concomitant injury by age. RESULTS: A total of 1,221 patients with facial injuries, reporting to our trauma center and outpatient department were identified. Majority of these injuries were encountered among boys (64%). Motor vehicle collision (46.5%) was the most common cause of facial fracture and dentoalveolar injuries in group II and group III, while fall was the most common cause among the group I (30.2%). Mandible was the most commonly fractured bone (34.7%) followed by nasal (33.3%), maxilla (17.5%), and zygoma (14.3%). More than 50% sustained concomitant injuries. CONCLUSION: The importance of epidemiological analysis lies in the identification of trauma burden, which could help motivate and develop more efficient ways to plan resources allocation and deliver adequate care and preventive steps. Improvisation upon National Prevention Programs could lower incidences of such injuries. HOW TO CITE THIS ARTICLE: Bhutia DP, Singh G, Mohammed S, et al.

Does pisiform subluxation affect the postoperative outcomes in a cohort of patients with distal radius fractures?

BACKGROUND: In this study, we retrospectively surveyed the presence or absence of pisiform subluxation in surgically treated distal radius fractures (DRF) cases. In addition, we investigated whether or not the postoperative short-term treatment outcome differs due to the presence of pisiform subluxation. MATERIALS AND METHODS: The subjects were 134 DRF patients treated with volar locking plate fixation (53 males and 81 females, mean age: 64 years old). The pisotriquetral joint was observed on a preoperative CT to investigate the presence or absence of pisiform subluxation according to the criteria reported by Vasilas. 134 patients divided into subluxation group and non-subluxation group, and the clinical outcomes were compared between these groups. RESULTS: Pisiform subluxation was noted in 23.1% (31 patients, 15 males and 16 females, mean age 61 years). No significant difference was noted in patient background in both groups. The postoperative pronation angle in the non-subluxation group was significantly greater than that in the subluxation group, but there was no significant difference in any other parameter (the range of motion of the wrist, grip strengths, VAS, Q-DASH scores, and Mayo score) between these 2 groups. However it concomitantly occurred in 23.1% of DRF cases in our series, there was no significant difference in the postoperative treatment outcome between these 2 groups. CONCLUSIONS: Therapeutic intervention of pisiform subluxation is unnecessary during treatment of DRF, since pisiform subluxation does not affect the postoperative clinical outcomes of distal radius fractures.

Fractures of the lateral tubercle of the talus (PLT) are rare. With the increasing popularity of the trend sport snowboarding, the incidence of PLT fractures has increased. The most common classification of PLT fractures is the Hawkins classification. The aim of this review was to raise awareness for the injury and discuss the current evidence. A literature search revealed eight studies, each including at least seven patients. Six out of the eight studies were descriptive, retrospective case series without predefined treatment concepts. These resulted in only moderate treatment outcomes. Due to the low number of patients, the lack of computed tomography (CT) or magnetic resonance imaging (MRI) and inconsistent treatment approaches, these studies do not allow to draw conclusions on a treatment concept for PLT fractures. The other two studies validated existing treatment regimens. Overall, surgical treatment of dislocated fractures and conservative treatment of non-dislocated fractures was carried out with satisfactory results. The outcome of conservative treatment of dislocated factures remains unclear. A reason for the inconsistent treatment results could be the observed concomitant injuries, including dislocation of the tendons of the peroneus muscles (46%), calcaneal chondral injuries (48%) and subluxation of the subtalar joint (7%). Based on the limited evidence available, the authors recommend the application of CT and MRI for PLT fractures to assess concomitant injuries, which are the primary indication for surgery. Dislocated type I and II fractures (>2 mm) should be treated operatively, type III and non-dislocated type I and II fractures can be treated conservatively by immobilization and partial weight-bearing for 6 weeks.
