Orthopaedic Diagnoses in the Black Pediatric Population.

The Black pediatric population is one that has been historically underserved and continues to have unmet needs. Factors including lack of diversity in orthopaedic studies and in historical standards, such as bone age, may inadvertently lead to inferior care. There are certain conditions in this population for which the practicing orthopaedic surgeon should have a higher degree of suspicion, including slipped capital femoral epiphysis, Blount disease, and postaxial polydactyly. Systemic diseases with higher rates in this population have orthopaedic manifestations, including sickle cell disease, vitamin D deficiency, and obesity. Racial discrepancies in access to prenatal care can have orthopaedic consequences for babies, especially cerebral palsy and myelodysplasia. Racial discrepancy exists in evaluation for nonaccidental trauma. Increased awareness of these issues better prepares practitioners to provide equitable care.

Trends in anti-osteoporotic medication utilization following fragility fracture in the USA from 2011 to 2019.

The aim of this study is to describe trends in the utilization of anti-osteoporotic medication after fragility fracture, including changes in the specific types of medications prescribed. Patients older than 65 with fragility fractures sustained from 2011 to 2019 were identified in the PearlDiver Patient Records Database. Osteoporosis treatment rate was defined as the rate at which patients were prescribed any of the fourteen most used anti-osteoporotic medications within 1year of fragility fracture. Fragility fractures were subcategorized by type. Treatment of fragility fractures was further stratified by patient demographics (age and gender) and medication type. This study showed an overall osteoporosis treatment rate of 8.01%, with treatment rates of 6.87% following hip fractures, 6.71% following upper extremity fractures, and 14.38% following vertebral compression fractures (VCF). From 2011 to 2018, there was no change in the overall fragility fracture treatment rate (p = 0.32). Of the three fracture categories analyzed, only the treatment rate for VCFs increased (p = 0.048). Osteoporosis treatment in patients with VCF increased among patients 65-74years old (p < 0.05) and male patients (p = 0.013). Treatment in patients with upper extremity fractures increased among patients 70-74years old (p = 0.038). Bisphosphonates were the most frequently prescribed class of medications. Bisphosphonates and denosumab increased in utilization (p = 0.049 and p < 0.001 respectively) while calcitonin utilization decreased (p < 0.001). Besides the overall low utilization rate of osteoporosis treatment in patients following fragility fractures, there has been no change in the treatment utilization rate within the past decade. More resources and interventions need to be enforced for all providers managing these patients if we are ever to address the osteoporosis epidemic.

The Effect of Rehabilitation Intervention on Pain, Strength, Range of Motion, Hand Function and Quality of Life Patients with Upper Extremity Fracture - A Systematic Review

BACKGROUND&#x0D; The rehabilitation intervention for upper extremity fracture varies from shoulder to finger, obtained from physical modalities and exercise. Physical modality and exercise rehabilitation intervention effectively reduce pain, increase range of motion (ROM), hand function and improve quality of life. This systematic review aims to synthesize current scientific knowledge on rehabilitative interventions with a specific focus on upper extremity fractures and the effect of all interventions on the patient.&#x0D; METHODS&#x0D; Three scholarly databases (PubMed, Google Scholar, Science Direct) were systematically searched. Literature published before 10 January 2022 focused on upper extremity fracture and rehabilitation treatment patients. Quality assessment was completed with CEBM tools by Oxford University. For PICO, The Population was upper extremity fractures, and the intervention was rehabilitation intervention, both physical modality and exercise. The comparation was other rehabilitation interventions or without rehabilitation, and the outcome in this study were measured with the visual analogue scale (VAS), ROM, hand function, and quality of life (QoL).&#x0D; RESULTS&#x0D; Eight studies were included in this review among 18.326 reference titles founded and screened. All of the studies had various sample sizes followed by bias analysis with CEBM tools. Rehabilitation for elbow fracture was dynamic fixation using rigid tape and proprioceptive neuromuscular facilitation stretching. Rehabilitation for distal radius fracture was scapular exercise, graded motor imagery, hot pack on hand volume, illusory kinesthesia, and wrist exercise. These interventions can reduce the pain, improve strength, range of motion, hand function and quality of life in upper extremity fracture patients.&#x0D; CONCLUSIONS&#x0D; Exercise and physical modality rehabilitation intervention have proven to reduce pain, improve strength, range of motion, hand function and quality of life in upper extremity fracture patients.

Preoperative coagulation biomarkers associate with survival and pulmonary embolism after surgical treatment of non-spinal skeletal metastases

BackgroundThrombotic complications are synergistic and associated with orthopedic procedures, trauma, and malignancy. Because cancer enhances coagulation activity and vice versa, we assessed preoperative biomarkers for survival and complications after treatment of pathologic fractures in non-spinal skeletal metastases.Patients/methodsOur study population comprised 113 actual or impending pathologic fractures in 100 patients admitted to two referral centers. Laboratory variables were collected retrospectively from patient records and analyzed related to incidence of pulmonary embolism (PE) and mortality (Kaplan-Meier and Cox regression analyses and biomarker quartiles).ResultsPreoperative coagulation variables were high without exceptions. PE occurred in 12 patients at 36 post-operative days at incidence of 11% in the lower and 13% in the upper extremity fractures. Patients with fibrinogen exceeding 5 g/l (log-rank 0.022) developed PE earlier (5 to 15 days postoperatively) than others. Also, mean patient survival with normal fibrinogen range (2–4 g/l) was 34 months, whereas it halved upon elevated fibrinogen (log-rank p = 0.009). Survival in patients with FVIII levels under 326 IU/dl (Q3) was 22 months, but only 7 months if FVIII exceeded 326 IU/dl (log-rank p = 0.002). Combined elevated fibrinogen and FVIII predicted survival: for patients with levels below threshold limits was 22 months versus only 7 months when both variables exceeded the ranges (log-rank p < 0.001). Multivariate analysis to control confounders supported an independent role of fibrinogen and FVIII for survival.ConclusionsOur study has established fibrinogen and FVIII as potential preoperative contributors of survival and complications after treatment of metastatic fractures. These results highlight the need for novel anticoagulation and thromboprophylaxis strategies among these patients.

A Makeshift Blue Light Filter for Endoscopic Identification of Traumatic Cerebrospinal Fluid Leak Using Fluorescein

&#x0D; &#x0D; &#x0D; &#x0D; ABSTRACTObjective: To describe a makeshift blue light filter for endoscopic visualization of a traumatic cerebrospinal fluid leak repair using intrathecal fluorescein and its application in one patient.&#x0D; &#x0D; &#x0D; &#x0D; &#x0D; Methods:Study Design:Surgical Instrumentation&#x0D; Setting:Tertiary Government Training Hospital&#x0D; Patient:One&#x0D; &#x0D; &#x0D; &#x0D; &#x0D; Results: Intra-operative endoscopic identification of fistulae sites was achieved using intrathecal injection of fluorescein that fluoresced using our makeshift blue light filter in a 43-year-old man who presented with a 3-month history of rhinorrhea due to skull base fractures along with multiple facial and upper extremity fractures he sustained after a fall from a standing height of 6 feet. He underwent transnasal endoscopic repair of cerebrospinal fluid fistulae in the planum sphenoidale, clivus and sellar floor. Post-operatively, there was complete resolution of rhinorrhea with no complications noted.&#x0D; &#x0D; &#x0D; &#x0D; &#x0D; Conclusion: Our makeshift blue light filter made from readily available materials may be useful for endoscopic identification of CSF leaks using fluorescein in a low- to middle-income country setting like ours.&#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D;

Pain Catastrophizing, Pain Self-Efficacy, and Kinesiophobia Effects on Outcomes After Upper Extremity Fracture

Pain Catastrophizing, Pain Self-Efficacy, and Kinesiophobia Effects on Outcomes After Upper Extremity Fracture

Do Anatomical Differences of the Volar Rim of the Distal Radius Affect Implant Design? A Three-Dimensional Analysis of Its Anatomy and Need for Personalized Medicine

The distal radius, one of the frequent sites of upper extremity fractures, includes unique anatomy referred to as the volar rim. Few studies have addressed its interindividual differences. Additionally, implants for osteosynthesis must match the anatomical structures to prevent soft tissue invasion, but no implants have focused on that so far. In this study, three-dimensional surface models were created from CT images of 101 cases. Analysis of the distal radius, including the volar rim anatomy, was performed to design plates to minimize the discrepancy between the bone anatomy and the implant. The results showed that there were considerable interindividual differences in the morphology of the distal radius, particularly in the degree of palmar protrusion of the volar rim. A moderate correlation between the width of the distal radius and the shape of the volar rim was demonstrated. Considering that variations in plate width are available for treatment of normal distal radius fractures and that the shape of the volar rim changes in correlation with the width of the bone, we infer that simply adding volar rim shape information to the current variations should suffice in preventing complications. We conclude that individualized design according to the shape of the volar rim is unnecessary in fracture surgery.

Two Minutes for Roughing: A National Analysis of Ice Hockey Injuries from American Trauma Centers.

Hockey is a high-impact sport that carries a risk of injury. No national-level studies defining the burden of injury in this sport have yet been performed. This study sought to analyze patient demographics, injury types and severity, and outcomes after trauma sustained while playing hockey. Retrospective analysis of hockey-related injuries was performed using the National Trauma Data Bank (NTDB) (2007-2018). Patients were identified based on ICD-9 and -10 codes without exclusions. Demographics, clinical/injury data, and outcomes were examined using univariate analysis. Subgroup analysis was performed by patient sex. Hockey injuries (n = 306) comprised <1% of the NTDB. Median age was 15years [IQR 13-25] (range 5-71). Most patients (n = 279, 91%) were male. Lower extremities were the most frequently injured body region (n = 88, 29%). Head injuries occurred in 19% (n = 57). Facial injuries occurred in 6% (n = 17). Tooth loss was infrequent (n = 2, 1%). One (<1%) death occurred after a hockey-related brain injury. Clinical/injury data between male and female hockey players were comparable apart from a significantly higher rate of upper extremity fractures among the female cohort (22% vs 4%, P < .001). Perceptions that hockey players may frequently sustain head, face, and tooth injuries from collisions, fighting, or stick/puck impacts were not supported by this national-level study, in which lower extremity fractures were the most common injury. While hockey injury prevention equipment has primarily focused on head/face protection (eg, helmets and mouthguards), this analysis suggests increased focus on extremity protective measures is warranted.

Denosumab treatment is associated with decreased cortical porosity and increased bone density and strength at the proximal humerus of ovariectomized cynomolgus monkeys.

Upper extremity fractures, including those at the humerus, are common among women with postmenopausal osteoporosis. Denosumab was shown to reduce humeral fractures in this population; however, no clinical or preclinical studies have quantified the effects of denosumab on humerus bone mineral density or bone microarchitecture changes. This study used micro-computed tomography (μCT) and computed tomography (CT), alongside image-based finite element (FE) models derived from both modalities, to quantify the effects of denosomab (DMAb) and alendronate (ALN) on humeral bone from acutely ovariectomized (OVX) cynomolgus monkeys. Animals were treated with 12 monthly injections of s.c. vehicle (VEH; n=10), s.c. denosumab (DMAb; 25mg/kg, n=9), or i.v. alendronate (ALN; 50μg/kg, n=10). Two more groups received 6months of VEH followed by 6months of DMAb (VEH-DMAb; n=7) or 6months of ALN followed by 6months of DMAb (ALN-DMAb; n=9). After treatment, humeri were harvested and μCT was used to quantify tissue mineral density, trabecular morphology, and cortical porosity at the humeral head. Clinical CT imaging was also used to quantify trabecular and cortical bone mineral density (BMD) at the ultra-proximal, proximal, 1/5 proximal and midshaft of the bone. Finally, μCT-based FE models in compression, and CT-based FE models in compression, torsion, and bending, were developed to estimate differences in strength. Compared to VEH, groups that received DMAb at any time demonstrated lower cortical porosity and/or higher tissue mineral density via μCT; no effects on trabecular morphology were observed. FE estimated strength based on μCT was higher after 12-months DMAb (p=0.020) and ALN-DMAb (p=0.024) vs. VEH; respectively, FE predicted mean (SD) strength was 4649.88 (710.58) N, and 4621.10 (1050.16) N vs. 3309.4 (876.09) N. All antiresorptive treatments were associated with higher cortical BMD via CT at the 1/5 proximal and midshaft of the humerus; however, no differences in CT-based FE predicted strength were observed. Overall, these results help to explain the observed reductions in humeral fracture rate following DMAb treatment in women with postmenopausal osteoporosis.

Is Elective Implant Removal after Fracture Healing Beneficial? - A Prospective Cohort Study.

Elective implant removal following healed extremity fractures remains controversial. This study aimed to evaluate the reasons and outcomes of implant removal after uneventful healing of limb fractures. This is a prospective single-centre observational cohort study. Patients who sustained upper or lower extremity fractures that were fixed and healed uneventfully were included in the study when they elected to remove the implants. Patients were followed for six months post-operatively. Outcomes were assessed with patient satisfaction, symptoms resolution, and complications. A total of 43 patients were recruited from October 2016 to March 2019. Thirty-six patients (37 implants) were symptomatic. Pain and prominence were the most common complaints, present in 59.5% and 33.3% of patients, respectively. Cold weather pain was also not uncommon (19.0%). Pain improved in 91.3% of the patients who complained of pain. The 94.6% symptomatic patients had at least partial resolution of pre-operative symptoms. All the patients who completed follow-up were satisfied with the procedure. In two patients, there were broken and retained screws intra-operatively. Post-operative complication rate was 23.8%, although no major complications occurred. Implant removal after uneventful healing of extremity fractures is a safe procedure that conferred a predictable relief of symptoms and satisfactory outcomes in most.

A New Normal: Trends of Upper Extremity Orthopaedic Injuries Nationwide During the COVID-19 Pandemic.

Background The widespread societal effects of the COVID-19 pandemic connote public health and epidemiological changes for orthopedic injuries. The epidemiology of upper extremity injuries and the effects of the pandemic on these nationwide trends is poorly defined. Methods This cross-sectional, descriptiveepidemiological study compares epidemiological trends among upper extremity (UE) orthopedic injuries presenting to emergency departments (EDs) prior to and during the COVID-19 pandemic. Upper extremity fracture and dislocation data was sourced from the National Electronic Injury Surveillance System (NEISS) database in years prior to (2015-2019) and during the pandemic (2020-2021). Data on incidence, patient demographics, injury patterns, mechanisms of injury, incident locale, and patient disposition were collected and compared between years. Results The pre-COVID-19 incidence rate (IR) of UE fractures at 2.03 per 1,000 persons (n=3038930 from 2015-2019) decreased to 1.84 per 1,000 in 2020 (n=474805) and 1.82 per 1,000 in 2021 (n=471793). Dislocation rates were largely unchanged at 0.34 per 1,000 people (n=476740) prior to the pandemic and with incidence rates of 0.33 per 1,000 (n=85582) and 0.34 per 1,000 (n=89386) in 2020 and 2021, respectively. Female patients over 65 had the highest injury IR at 4.85 per 1,000 (n=976948). Finger fractures (IR=0.38 per 1000, n=96009) overtook hand fractures (IR=0.51 per 1000, n=310710) as more common during COVID-19 in males, while wrist (IR=0.55 per 1000, n=350650) fractures remained most common in females. Injuries from individual sports, such as skateboarding and bicycling, increased during the pandemic, while injuries from team sports decreased. Hospital admission and observation increased in 2020, while discharge and transfer rates decreased. Admission, observation, and discharge rates moved closer to pre-pandemic levels in 2021. Conclusions The COVID-19 pandemic was associated with epidemiological and activity changes regarding UE fractures and dislocations presenting to EDs. The present study demonstrates notable decreases in rates of upper extremity fractures and dislocations, increases in rates of injuries related to outdoor and individual sports such as skateboarding with corresponding decreases in rates of injuries related to organized sports such as basketball, increases in the rates of injuries occurring in homes and in association with pet supplies, and decreases in rates of injuries occurring in schools and places of recreationobserved during the pandemic.Additionally, trends observed among patient disposition specific to the pandemic, such as increasing rates of patient admission, observation, and against medical advice (AMA) departure with decreasing rates of discharge and transfer, offer insight into the burden of upper extremity injuries on the healthcare system during this critical time. While upper extremity orthopedic injuries remained common through the pandemic, the early pandemic was associated with higher rates of hospital admission that normalized closer to pre-pandemic levels by 2021, which may herald a shift and return to pre-pandemic trends. Future research will determine the long-term downstream effects of COVID-19 on activity-related orthopedic injuries and bone health.

Management of upper limb diaphyseal and metaphyseal fractures (Humerus, Radius and Ulna) with application of extension cast

To manage fracture either no operative or operative techniques is required. If the fracture is significantly displaced or angulated, a closed reduction should be done followed by a period of immobilization with casting or splinting is a basics of no operative approach. The aim of this study is to evaluate results of Management of Upper Limb Diaphysis and Metaphyseal Fractures (Humerus, Radius and Ulna) with Application of Extension Cast in closed fractures in adults to assess the functional acceptance of the procedure. To assess the efficacy and advantage of this treatment. The study included upper arm fracture patients. Fixed criterion was discouraged for a definite sample size and it was considered to take up as many cases as possible from trauma centre on every Wednesday in the entire period of data collection i.e., from of September 2020 and May 2022. Forty-two newly diagnosed cases of the fracture of upper extremities whose radiological and clinical record were intact. Patients in extension casting group were followed up from 14 to 22 months, with an average of (17.34±2.61) months. The full-length cast was applied from 4 to 6 weeks with a mean of 5 weeks. All casts were converted to the above elbow cast when the fracture became sticky. Radiological evidence of a fluffy callus appeared at an average of 35 days and bony union was achieved at a mean of (3.48±0.59) months. In current study after 1 year of treatment, the mean range of motion of all joints of affected limb became normal the mean VAS score after 6 weeks was 8 after 3 months the mean VAS score was 4 and after 6 months the mean was score was 1. Extension cast allows gravity to work all the time which is especially beneficial for comminuted fractures. This reduces the chances of limb shortening.

Non-Inferiority of Point-of-Care Ultrasound Compared to Radiography to Diagnose Upper Extremity Fractures in Children.

Conventional X-ray imaging for fracture diagnosis is time-consuming and exposes patients to ionizing radiation. Additionally, the positioning of the injured limb for standardized X-ray imaging is painful. Point-of-care ultrasound (POCUS) is increasingly available in medical offices and emergency rooms. This study aimed to prove the non-inferiority of POCUS compared to X-ray imaging with respect to diagnostic sensitivity, pain, and investigation time in the diagnosis of long-bone fractures of the upper extremity in children. Children and adolescents (1–18 years old) presenting to the UKBB emergency service between May 2020 and May 2021 with suspected upper extremity fracture were included in the study. Before obtaining X-ray images, we conducted a POCUS examination of the injured limb. Pain scores at inclusion as well as maximum pain scores during X-ray and ultrasound examinations were documented. The duration of POCUS and X-ray examinations was compared. We examined 403 children with POCUS and plain X-ray imaging. The mean age (±SD) of the children was 10.6 (±3.5) years. The non-inferiority of POCUS compared to X-ray was confirmed with an estimated sensitivity of 0.95 and a lower confidence interval of 0.93. Maximum pain during POCUS was significantly lower compared to pain at inclusion (p = 0.002) or maximum pain during radiographic examination (p = 0.03). POCUS examination took 3.9 (±2.9) min in the mean whilst the mean duration for obtaining the X-ray images was 16 (±37) min (p < 0.001). POCUS for diagnosing upper extremity fractures in children proved as sensitive as standard X-ray imaging and was significantly faster and less painful. Future prospective studies are required to confirm our findings.

Race, Gender, and Primary Language Were Not Associated With Changes in Opioid Prescribing in Children: Results From a Single Institution, 2010 to 2020.

Patients should be prescribed medication based on their medical condition, without prejudice because of their race, gender, or primary language. However, previous research has shown that men are prescribed more medication than women, patients who are White are prescribed more medications than patients who are non-White, and English-speaking people are prescribed more medications than non-English-speaking patients. However, it is unclear whether these differences also occur in pediatric orthopaedic populations. We asked: (1) Was the amount of opiates prescribed at discharge associated with patient age, gender, race, or primary language? (2) Did the amount of opiates prescribed to patients at discharge change from 2010 to 2020? In a single center, between January 2010 and December 2019, we treated 331 patients younger than 18 years surgically for upper and lower long-bone extremity fractures. Patients were considered eligible if they had a nonpathologic fracture. Femur fractures were not included. Based on these criteria, all patients were eligible. The mean age was 12 ± 4 years. The mean weight was 57 ± 33 kg. Among these patients, 76% (253 of 331) were boys and 24% (78 of 331) were girls. From the hospital discharge records, we recorded the amount of opiates prescribed at the time of discharge as measured by morphine milligram equivalents (MMEs). We examined the association of age, gender, race, primary language, weight, and year of treatment using this measurement. We determined a patient's race retrospectively by information given by their parents at time of admission. We did not attempt to contact patients to obtain more nuanced information about their racial background. These data were obtained from the electronic health record. The Wilcoxon rank sum test, t-test, or chi-square test was used to assess associations depending on the distribution of variables, as appropriate. Because opioids as measured in MMEs is zero-inflated, a two-part model analysis was used to adjust for confounding variables. One component of the model was for the probability of having any opiate prescription and another was for the mean number of opioids received. Findings were considered statistically significant if p values were < 0.05. In total, 57% (189 of 331) of children were prescribed opiates at discharge after surgery for long-bone fractures. Opiate MMEs increased with patient age (r = 0.38; p < 0.01). Boys and girls showed no difference in the amounts of pain medication (adjusted odds ratio [OR] 1.38 [95% confidence interval (CI) 0.80 to 2.39]; p = 0.71; adjusted opioid difference: 0.35 MME [95% CI -51.7 to 52.4]; p = 0.99), nor were there differences between patients who were White and those who were non-White (adjusted OR 0.78 [95% CI 0.49 to 1.23]; p = 0.28; adjusted opioid difference: 21.5 MME [95% CI -19.3 to 62.4]; p = 0.30), or between patients for whom English was there primary language and those for whom English was not their primary language (adjusted OR 1.16 [95% CI 0.52 to 2.57]; p = 0.71; adjusted opioid difference: 22.7 MME [95% CI -55.7 to 101.3]; p = 0.57) when adjusted for age and weight. There was no change in opioid prescription amounts from 2010 to 2020 after adjusting for changes in patient age across years (Spearman r = -0.08; p = 0.16). Fairness in opioid prescribing based on race, gender, or primary language is possible. Additional research is needed to determine what factors in our institution led to this result. We suggest that prescribers should apply consistent protocols based on factors such as weight or injury type rather than making individual decisions for each patient. This will lead to fairer opioid prescribing to patients from different race and gender groups. Level III, therapeutic study.

Effects of muscle quantity and bone mineral density on injury and outcomes in older adult motor vehicle crash occupants

Objectives: Quantify the independent and combined effects of abdominal muscle quantity and lumbar bone mineral density (BMD) on injury risk and in-hospital outcomes in severely injured motor vehicle crash (MVC) occupants ages 50 and older. Methods: Skeletal muscle area measurements of MVC occupants were obtained through semi-automated segmentation of an axial computed tomography (CT) slice at the L3 vertebra. An occupant height-normalized Skeletal Muscle Index (SMI) was calculated - a defining metric of sarcopenia and low muscle mass (sarcopenia thresholds: <38.5 cm2/m2 females; <52.4 cm2/m2 males). Lumbar BMD was obtained using a validated, phantomless CT calibration method (osteopenia threshold: <145 mg/cm3). SMI and BMD values were used to categorize occupants, and logistic regression was used to associate sarcopenia, osteopenia, and osteosarcopenia predictors to injury outcomes (e.g., Injury Severity Score (ISS), maximum Abbreviated Injury Scale (MAIS) score, fractures) and hospital outcomes (e.g., length of stay, ICU days). Results: Of the 336 occupants, 210 (63%) were female (mean ± SD: age 66.3 ± 10.6). SMI was 41.7 ± 8.0 cm2/m2 in females and 51.2 ± 10.8 cm2/m2 in males. Based on SMI, 40% of females and 55% of males were classified as sarcopenic. BMD was 163.2 ± 38.3 mg/cm3 in females and 164.1 ± 35.4 mg/cm3 in males, with 41% of females and 33% of males classified as osteopenic. Prevalence of both conditions (osteosarcopenia) was similar between females (21%) and males (22%). Incidence of low SMI and BMD increased with age. Sarcopenic individuals were less likely to sustain a MAIS 2+ thorax injury and had longer ICU stays. Osteopenic individuals were more likely to sustain upper extremity injuries and fractures, and were less likely to be discharged to a rehabilitation facility. Osteosarcopenic individuals were less likely to be ventilated or admitted to the ICU but tended to spend more time on the ventilator if placed on one. Conclusions: Osteosarcopenia was not associated with any injury outcomes, but sarcopenia was associated with thoracic injury and osteopenia was associated with upper extremity injury incidence. Sarcopenia was only associated with ICU length of stay, while osteopenia was only associated with discharge destination. Osteosarcopenia was associated with likelihood of being ventilated, being admitted to the ICU, and with increased length of ventilation.

Epidemiology of ballistic fractures in the United States: A 20-year analysis of the Firearm Injury Surveillance Study

IntroductionBallistic (i.e., gunshot-induced) fractures present unique treatment challenges and can be associated with high rates of complications and considerable morbidity. Large-scale epidemiologic data on these types of fractures are scarce. There is concern that gun-related violence may be on the rise, potentially increasing the burden of ballistic orthopaedic trauma, but there are few contemporary studies on the topic. The aim of this study, therefore, was to investigate the incidence and demographics of patients with ballistic fractures in the United States (US) over the last 20 years. Materials and MethodsThis descriptive epidemiology study retrospectively analyzed the Firearm Injury Surveillance Study to identify cases of ballistic fractures in the US from 2000 to 2019. Overall and annual numbers of fractures and fracture incidence rates (IRs), patient demographics, incident characteristics, and temporal trends were analyzed. Patients of all ages were included. Ballistic fractures were grouped by anatomic location for comparisons (non-spine axial, spine, upper extremity, lower extremity). ResultsAn estimated N = 240,555 patients (n = 8,322 unweighted cases) sustained ballistic fractures over the 20-year study period for an overall IR of 39.2 per 1,000,000 person-years at-risk (PYR). Overall, lower extremity fractures accounted for the largest percentage of cases (45.9%; IR=18.8 PYR), followed by upper extremity fractures (32.8%; IR=13.4 PYR), non-spine axial fractures (16.1%; IR=6.6 PYR), and spine fractures (5.2%; IR=2.1 PYR). Diaphyseal femur fractures were the most common ballistic fractures overall. Nearly three-fourths (71.2%) of all cases occurred in males in the second through fourth decades. The most common injury intent was assault (71.8%) and a majority of patients (71.2%) required hospital admission. Accounting for population growth yielded a significantly increasing incidence of all ballistic fractures over the study period from 15.7 PYR in 2000 to 96.8 PYR in 2019 (average annual percent change=10.3, p < 0.00001). ConclusionThese data suggest that the nationwide burden of ballistic fractures in the US has increased significantly in the last two decades. Ballistic fractures are associated with significant morbidity and societal cost, and increasing injury rates highlight the need for future research aimed at better understanding the ideal treatment of these types of fractures and their outcomes.

Association between cause of kidney failure and fracture incidence in a national US dialysis population cohort study.

Whether fracture rates, overall and by fracture site, vary by cause of kidney failure in patients receiving dialysis is unknown. Using the US Renal Data System, we compared fracture rates across seven causes of kidney failure in patients who started dialysis between 1997 and 2014. We computed unadjusted and multivariable adjusted proportional sub-distribution hazard models, with fracture events (overall, and by site) as the outcome and immunoglobulin A nephropathy as the reference group. Kidney transplantation and death were competing events. Among 491 496 individuals, with a median follow-up of 2.0 (25%, 75% range 0.9-3.9) years, 62 954 (12.8%) experienced at least one fracture. Patients with diabetic nephropathy, vasculitis or autosomal polycystic kidney disease (ADPKD) had the highest (50, 46 and 40 per 1000 person-years, respectively), and patient with lupus nephritis had the lowest (20 per 1000 person-years) fracture rates. After multivariable adjustment, diabetic nephropathy [hazard ratio (HR) 1.43, 95% confidence interval 1.33-1.53], ADPKD (HR 1.37, 1.26-1.48), vasculitis (HR 1.22, 1.09-1.34), membranous nephropathy (HR 1.16, 1.02-1.30) and focal segmental glomerulosclerosis (FSGS) (HR 1.13, 1.02-1.24) were associated with a significantly higher, and lupus nephritis with a significantly lower (HR 0.85, 0.71-0.98) fracture hazard. The hazards for upper extremity and lower leg fractures were significantly higher in diabetic nephropathy, ADPKD, FSGS and membranous nephropathy, while the hazard for vertebral fracture was significantly higher in vasculitis. Our findings were limited by the lack of data on medication use and whether fractures were traumatic or non-traumatic, among other factors. Fracture risk, overall and by fracture site, varies by cause of end-stage kidney disease. Future work to determine underlying pathogenic mechanisms contributing to differential risks might inform more tailored treatment strategies. Our study was limited by lack of data regarding numerous potential confounders or mediators including medications and measures or bone biomarkers.

Outcome evaluation of proximal humerus fractures management by proximal humeral internal locking plates- A clinico- radiological study

Introduction: Proximal humerus fractures are amongst the most common upper extremity fractures that are found in elderly as well as young age groups. Although majority of them are treated conservatively, due to the demand for early return to the daily activities and problems of late collapse/ displacement with conservative measures there arise a need for plate ostesynthesis. Amongst the various methods of fixation, Proximal humerus intrlocking plates designs promise an opportunity to minimize the common complicsations. However, a gap still exists between in vitro results and clinical outcomes. Addressing to the limitations and need to evaluate the efficacy of the currently available proximal humerual interlocking plates, the purpose of this study will be to evaluate the short and medium term functional resultys with fixation of proximal humerus fracture and review the common complications associated. Materials and methods: In this prospective observational study, conducted at a tertiary care centre, patients from 18-85 age group were selected according to the inclusion and exclusion criteria.

Impact of concomitant upper-extremity injuries in patients with hip fractures: a systematic review and meta-analysis.

Combined hip and upper-extremity fractures raise clinical concerns because upper-extremity fractures may hinder early mobilization, thereby affecting rehabilitation and mortality. This systematic review and meta-analysis aimed to evaluate the effects of combined upper-extremity and hip fractures on rehabilitation and mortality. We systematically searched MEDLINE, Embase, and the Cochrane Library for studies published before March 20, 2022, that evaluated the impact of concomitant upper-extremity injuries in geriatric patients with hip fractures. The pooled analysis identified differences in the (1) length of hospital stay, (2) discharge destination, and (3) mortality rates between the isolated and combined hip fracture groups. A total of 217,233 patients with isolated hip fractures (n = 203,816) and combined hip and upper-extremity fractures (n = 13,417) from 12 studies were analyzed. The average length of hospital stay was significantly longer in the combined upper-extremity fracture group than in the isolated hip fracture group (mean difference = 1.67days; 95% confidence interval [CI] 0.63-2.70; P = 0.002). Patients in the combined upper limb fracture group were less likely to be discharged directly home (odds ratio [OR] = 0.64; 95% CI 0.52-0.80; P < 0.001) and showed significantly higher 30-day mortality (OR = 1.44; 95% CI 1.32-1.58; P < 0.001). The mortality rate after 30days was not significantly different between the two groups. Concomitant upper-extremity fractures have debilitating effects on rehabilitation and early mortality in geriatric patients with hip fractures. Therefore, more focus should be placed on the early ambulation of patients with hip fractures and simultaneous upper limb fractures to promote rehabilitation and alleviate the public health burden.

Surgical site infection in upper extremity fracture: Incidence and prognostic risk factors.

Upper extremity fractures (UEF) occurred in about 0.67% of males and females at some point in their lifetime. Surgical treatment has the advantage of good functional recovery, however, the occurrence of surgical site infection (SSI) affects the clinical outcome of operation. Currently, there are few studies focused on SSI of UEF. Consecutive patients with UEF and underwent surgeries from January 2010 to February 2021 were recruited. Demographic data, surgical related variables and laboratory test index of these patients were extracted and collected from the electronic medical records and picture archiving and communication system by well-trained investigators. Receiver operating characteristic (ROC) analysis was performed to detect the optimum cut-off value for continuous variables. Multivariate logistic regression analysis was performed to identify independent risk factors of SSI. In total, 286 patients with a mean age of 44.4 ± 16.6 years were identified for inclusion, 59.8% patients diagnosed with fracture of radius and ulna and 40.2% fractures located in the humerus, closed and open fractures were occurred in 252 and 34 adult patients respectively. 7.3% UEF patients were encountered with SSI, incidence of superficial and deep infection was 6.3% and 1.0%. Open fracture (OR, 8.33; P, .000), operation time longer than 122 minutes (OR, 3.12; P, .036), intraoperative blood loss more than 135 mL (OR, 3.98; P, .009) and albumin (ALB) lower than 40.8 g/L (OR, 3.60; P, .015) were demonstrated as independent risk factors of SSI. Adequate preoperative evaluation, careful intraoperative manipulation, and timely and appropriate postoperative interventions should be formulated to reduce the incidence of SSI in patients with the above perioperative high-risk factors.
