Patients With Preexisting Anxiety and Mood Disorders Are More Likely to Develop Complex Regional Pain Syndrome After Fractures.

BACKGROUND: Complex regional pain syndrome (CRPS) is a multifactorial condition that may affect patients who sustain a fracture in the upper and lower extremities. Prior investigations have formed a foundation for exploring a possible association between psychiatric disorders and the development of CRPS; however, current studies are conflicted regarding the existence and temporality of a relationship between psychiatric disorders and the potential development of CRPS. QUESTIONS/PURPOSES: (1) Are patients with preexisting anxiety and mood disorders (AMDs) at increased risk of receiving a diagnosis of CRPS after upper or lower extremity fractures? (2) Are patients with preexisting AMDs at increased risk of being diagnosed with CRPS after surgical fixation of their fracture? METHODS: A large, retrospective cohort study was conducted using the TriNetX electronic medical record platform, which contains data from more than 100 million patients. This platform gathers data from healthcare organizations in the United States and Europe and collects comprehensive data over time that includes temporality rather than simply the binary presence or absence of conditions. The cohort included 760,595 patients older than 18 years with upper or lower extremity fractures between 2003 and 2022. Included patients had a minimum 1-year follow-up. We defined AMDs as any diagnosis of anxiety, depressive episode or disorder, a manic episode, or bipolar disorder. Patients with polytrauma or concurrent upper and lower extremity fractures were excluded to reduce confounders. CRPS I diagnosis was identified via International Classification of Diseases, Tenth Edition codes. Propensity score matching was performed to balance cohorts based on age, gender, and race. Hazard ratios and Aalen-Johansen cumulative incidence curves for the diagnosis of CRPS were calculated for patients with and without AMD diagnoses before sustaining a fracture. A subanalysis was performed in which we examined individuals in the upper and lower extremity fracture cohorts who underwent surgical treatment. RESULTS: Patients with preexisting AMDs were at a higher risk of experiencing CRPS I than patients without AMDs were (upper extremity: HR 1.8 [95% CI 1.7 to 1.9]; p < 0.01, lower extremity: HR 2.2 [95% CI 2.0 to 2.3]; p < 0.01). Similarly, patients with preexisting AMDs were at higher risk of experiencing CRPS I after fracture fixation than patients without AMDs were (upper extremity: HR 1.3 [95% CI 1.2 to 1.5]; p < 0.01, lower extremity: HR 2.3 [95% CI 2.1 to 2.5]; p < 0.01). CONCLUSION: Awareness of the relationship between AMDs and CRPS I will direct future research about the development of this condition and associated neurologic changes. Additionally, surgeons can address AMDs perioperatively and arrange for the treatment of these AMDs with psychiatrists, neurologists, or social work, as appropriate. Accordingly, patients with AMDs should also be made aware of the inherent risk of CRPS I after an upper or lower extremity fracture to comprehensively educate and care for this at-risk patient population.

Risk Factors for Stiffness After Surgical Treatment of Pediatric Humeral Lateral Condyle Fractures: Results of a Multicenter Study.

INTRODUCTION: Pediatric humeral lateral condyle fractures are the second most common elbow fractures. Their treatment presents challenges due to physeal and intra-articular involvement. Postoperative stiffness is a common concern that can limit limb functionality. This study aims to identify risk factors for postoperative stiffness in a large cohort of these fractures across multiple institutions. METHODS: A large, multicenter retrospective review of medical records from 6 level I trauma centers was conducted. Data from children aged 1 to 12 years with lateral condyle fractures treated between 2005 and 2019 were collected. Elbow stiffness was defined in the present study as having a limited elbow ROM that led to requiring a physical or occupational therapy referral or needing surgical treatment to address stiffness. Relevant patient demographics, fracture characteristics, treatment approaches, and complications were analyzed. RESULTS: Six hundred sixty-five fractures were analyzed. The average patient age was 8.8 years with 21% experiencing stiffness. The stiffness group had older patients, a higher incidence of elbow dislocations, a higher rate of open reduction, and more severe fracture patterns. Multivariate regression analysis identified open reduction, increased age, and concurrent elbow dislocation as significant risk factors for stiffness. Patients with stiffness commonly utilized only physical or occupational therapy (96%), while a small percentage (4%) required surgical interventions. CONCLUSIONS: This study highlights the risk factors for postoperative stiffness in pediatric humeral lateral condyle fractures, namely increased age, concomitant elbow dislocation, and treatment with open reduction. Families of older patients or severe fracture patterns requiring open reduction and those with concurrent elbow instability should be counseled about their increased risk of stiffness. The authors recommend initially attempting a closed reduction in high-risk patients to help mitigate the risk of postoperative stiffness. Early initiation of range of motion exercises may also be beneficial for at-risk patients. LEVEL OF EVIDENCE: Level III: Therapeutic studies-Investigating the results of treatment.

Epidemiology of Pediatric Firearm Injuries in the United States: The Progression of Gunshot Injury Rates Through the Coronavirus Disease 2019 Pandemic.

OBJECTIVES: Ballistic injuries among pediatric populations have become a public health crisis in the United States. The surge in firearm injuries among children has outpaced other causes of death. This study aims to assess the trend in pediatric gunshot injuries (GSIs) over the last decade and investigate the impact, if any, of the pandemic on GSIs statistics. METHODS: A comprehensive retrospective analysis was conducted using a federated, real-time national database. A total of 15,267,921 children without GSIs and 6261 children with GSIs between 2017 and 2023 were identified. The study evaluated the incidence and annual proportions of GSIs among different demographics. In addition, the incidence proportions per 100,000 for accidental, nonaccidental, fracture-related, and fatal GSIs were analyzed. RESULTS: The incidence proportions per 100,000 for GSIs, accidental GSIs, nonaccidental GSIs, fatal GSIs, wheelchair-bound cases, and fracture-related GSIs increased significantly from 2017 to 2023, going from 9.7 to 22.8 (Relative Risk: 2.342, 95% CI: 2.041, 2.687, P < 0.001). The overall increase was mostly a result of accidental GSI when compared with nonaccidental (incidence proportion 25.8 vs 2.1; P < 0.001) in 2021 at the height of the pandemic. In patients with an accidental GSI, the incidence proportion per 100k between 2017 and 2023 increased from 8.81 to 21.11 (Relative Risk: 2.397, 95% CI: 2.076, 2.768, P < 0.001). CONCLUSION: The study supports the shift in the leading cause of death among children from motor vehicle accidents to GSIs, with the continued rise in rates despite the coronavirus disease 2019 pandemic. Accidental injuries constituted the majority of GSIs, indicating the need for enhanced gun safety measures, including requirements for gun storage, keeping firearms locked and unloaded, requiring child supervision in homes with guns, and enforcing stricter punishments as penalties. Comprehensive efforts are required to address this public health crisis. Pediatricians play a vital role in counseling and educating families on firearm safety. LEVEL OF EVIDENCE: Level III.

Closed Reduction Techniques Are Associated With Fewer Complications Than Open Reductions in Treating Moderately Displaced Pediatric Lateral Humeral Condyle Fractures: A Multicenter Study.

INTRODUCTION: Lateral humeral condyle (LC) fractures are the second most common pediatric elbow fractures. Traditionally, displaced fractures have been treated with open reduction although recent studies have demonstrated successful outcomes of closed reduction for similar injuries. This study investigates the outcomes comparing open and closed reduction in a large cohort of children with moderately displaced (Song classification types 1 to 4) lateral humeral condyle fractures. METHODS: Retrospective data from patients aged between 1 and 12 years treated for lateral condyle fractures was collected from 6 academic level 1 trauma centers between 2005 and 2019. Data was collected on patient demographics, radiographic parameters, reduction type, type of hardware fixation, and fracture patterns. Complications recorded include infections, reoperations for nonunion, osteonecrosis, and elbow stiffness. RESULTS: An initial 762 fractures were identified. After excluding Song 5 cases, a total of 480 fractures met inclusion criteria, with 202 (42%) treated with closed reduction and 278 (58%) treated with open reduction. Demographics and injury characteristics were similar across the 2 reduction cohorts. After propensity score matching, delayed healing (52% vs. 28%; OR: 2.88, 95% CI: 1.97-4.22; P<0.0001) and stiffness (22% vs. 10%; OR 2.42, 95% CI: 1.42-4.13; P=0.0012) were significantly higher in the open reduction group. No differences in the rates of infection or nonunion (3% CR and 1% OR) were noted between the 2 groups. CONCLUSION: This study demonstrates that moderately displaced lateral condyle fractures requiring open reduction are more likely to have elbow stiffness and delayed healing when compared with the ones treated with closed reduction. For these reasons, we propose attempting closed reduction techniques as the first line of treatment in moderately displaced lateral humeral condyle fractures (if anatomic articular reduction can be achieved) to attain better patient outcomes.

Prior Bariatric Surgery Is Associated With Improved Total Hip Arthroplasty Outcomes in Patients Who Have Obesity: A National Cohort Study With 6 Years of Follow-Up.

BACKGROUND: Obesity is a risk factor for end-stage hip osteoarthritis. While total hip arthroplasty (THA) is commonly performed to reduce pain and improve function associated with osteoarthritis, obesity has been associated with an increased risk of complications after THA. Although bariatric surgery may also be utilized to reduce weight, the impact of bariatric surgery on THA outcomes remains inadequately understood. METHODS: This retrospective cohort analysis utilized multicenter electronic medical record data ranging from 2003 to 2023. Patients who have obesity who underwent THA were stratified based on prior bariatric surgery. The final bariatric cohort comprised 451 patients after propensity score matching. Complication rates and revision risks were compared between cohorts at 6, 24, and 72 months. Additional analysis stratified patients by interval between bariatric surgery and THA. RESULTS: At 6-month follow-up, the bariatric cohort had significantly lower risks of surgical site infection, wound dehiscence, and deep vein thrombosis (DVT). At 24 months, the bariatric cohort had a lower risk of DVT. At 72-month follow-up, the bariatric cohort had reduced rates of revision, mortality, cardiac morbidity, and Clavien-Dindo grade IV complications. CONCLUSIONS: Obese patients who underwent bariatric surgery prior to THA experienced reduced medical complications at all time points and reduced rates of revision at 72 months relative to a matched cohort who did not undergo bariatric surgery.

Lumbopelvic fixation in the treatment of spinopelvic dissociation: union, complications, and neurologic outcomes of a multicenter case series.

PURPOSE: To review outcomes of spinopelvic dissociation treated with open lumbopelvic fixation. METHODS: We reviewed all cases of spinopelvic dissociation treated at three Level-I trauma centers with open lumbopelvic fixation, including those with adjunctive percutaneous fixation. We collected demographic data, associated injuries, pre- and postoperative neurologic status, pre- and postoperative kyphosis, and Roy-Camille classification. Outcomes included presence of union, reoperation rates, and complications involving hardware or wound. RESULTS: From an initial cohort of 260 patients with spinopelvic dissociation, forty patients fulfilled inclusion criteria with a median follow-up of 351 days. Ten patients (25%) had a combination of percutaneous iliosacral and open lumbopelvic repair. Average pre- and postoperative kyphosis was 30 degrees and 26 degrees, respectively. Twenty patients (50%) had neurologic deficit preoperatively, and eight (20%) were unknown or unable to be assessed. All patients presenting with bowel or bladder dysfunction (n = 12) underwent laminectomy at time of surgery, with 3 patients (25%) having continued dysfunction at final follow-up. Surgical site infection occurred in four cases (10%) and wound complications in two (5%). All cases (100%) went on to union and five patients (13%) required hardware removal. CONCLUSION: Open lumbopelvic fixation resulted in a high union rate in the treatment of spinopelvic dissociation. Approximately 1 in 6 patients had a wound complication, the majority of which were surgical site infections. Bowel and bladder dysfunction at presentation were common with the majority of cases resolving by final follow-up when spinopelvic dissociation had been treated with decompression and stable fixation.

Disparities Exist in the Experience of Financial Burden Among Orthopedic Trauma Patients: A Systematic Review.

PURPOSE OF REVIEW: There are substantial costs associated with orthopedic injury and management. These costs are likely not experienced equally among patients. At the level of the healthcare and hospital systems, disparities in financial burden and patient demographics have already been identified among orthopedic trauma patients. Accordingly, disparities may also arise at the level of the patient and how they experience the cost of their care. We sought to determine (1) how patient demographics are associated with financial burden/toxicity and (2) if patients experience disproportionate financial burden/toxicity and social support secondary to their economic standing. RECENT FINDINGS: It has been described that there is an inequitable experience in clinical and economic outcomes in certain socioeconomic demographics leading to disparities in financial burden. It has been further reported that orthopedic injury, management, and outcomes are not experienced equitably among all demographic and socioeconomic groups. Ten articles met inclusion criteria, among which financial burden was disproportionately experienced amid orthopedic trauma patients across age, gender, race, education, and marital status. Financial hardship was also unequally distributed among different levels of income, employment, insurance status, and social deprivation. Younger, female, non-White, and unmarried patients experience increased financial burden. Patients with less education, lower income, limited or no insurance, and greater social deprivation disproportionately experienced financial toxicity compared to patients of improved economic standing. Further investigation into policy changes, social support, and barriers to appropriate care should be addressed to prevent unnecessary financial burden and promote greater patient welfare.

Radiological Outcomes of Magnetically Controlled Growing Rods for the Treatment of Children with Various Etiologies of Early-Onset Scoliosis-A Multicenter Study.

Background: The management of spinal deformities diagnosed before the age of 10 is critical due to the child's development, skeletal system, and growth mechanism. Magnetically controlled growing rods (MCGRs) are a surgical treatment option for the growing spine. The aim of this study was to analyze the radiological findings of patients treated with MCGRs for early-onset scoliosis (EOS) of various etiologies. We hypothesized that the MCGRs could provide acceptable long-term radiographic results, such as an increase in the T1-T12 and T1-S1 height and significant overall deformity correction. Methods: We retrospectively reviewed 161 EOS patients with a combined total of 302 MCGRs inserted at five institutions between 2016 and 2022 with a mean follow-up of at least two years. The Cobb angle of the major curve (MC), thoracic kyphosis (TK), lumbar lordosis (LL), and T1-T12 and T1-S1 height measurements were assessed before, after, and during the follow-up. Results: Among the 90 female and 71 male patients, there were 51 neurological, 42 syndromic, 58 idiopathic, and ten congenital scoliosis etiologies. Of the patients, 73 were aged under six years old. The mean follow-up time was 32.8 months. The mean age at placement of the MCGRs was 7 years and that at the last follow-up after fusion surgery was 14.5 years. The mean MC before the initial surgery was 86.2°; following rod implantation, it was 46.9°, and at the last follow-up visit, it was 45.8°. The mean correction rate among the etiology subgroups was from 43% to 50% at follow-up. The mean TK was noted as 47.2° before MCGR implantation, 47.1° after MCGR placement, and 44.5° at the last follow-up visit. The mean T1-T12 height increased by 5.95 mm per year, with a mean T1-S1 height of 10.1 mm per year. Conclusions: MCGR treatment allowed for an average correction of the curvature by 50% during the period of lengthening, while controlling any deformity and growth of the spine, with a significant increase in the T1-T12 and T1-S1 values during the observation period. MCGR treatment in EOS carries a risk of complications. While congenital and syndromic EOS often have short and less flexible curves in those groups of patients, single rods can be as effective and safe. Definitive fusion results in the mean final coronal correction between the start of MCGR treatment and after undergoing PSF of approximately 70%. The mean T1-T12 spinal height increased by 75 mm, while the T1-S1 spinal height gained a mean of 97 mm.

The shifting trends in the epidemiology and risk factors of non-accidental fractures in children.

BACKGROUND: Fractures are a common presentation of non-accidental trauma (NAT) in the pediatric population. However, the presentation could be subtle, and a high degree of suspicion is needed not to miss NAT. OBJECTIVE: To analyze a comprehensive database, providing insights into the epidemiology of fractures associated with NAT. PARTICIPANTS AND SETTING: The TriNetX Research Network was utilized for this study, containing medical records from 55 healthcare organizations. TriNetX was queried for all visits in children under the age of 6 years from 2015 to 2022, resulting in a cohort of over 32 million. METHODS: All accidental and non-accidental fractures were extracted and analyzed to determine the incidence, fracture location, and demographics of NAT. Statistical analysis was done on a combination of Python and Epipy. RESULTS: Overall, 0.36 % of all pediatric patients had a diagnosis of NAT, and 4.93 % of fractures (34,038 out of 689,740 total fractures) were determined to be non-accidental. Skull and face fractures constituted 17.9 % of all NAT fractures, but rib/sternum fractures had an RR = 6.7 for NAT. Children with intellectual and developmental disability (IDD) or autism spectrum disorder (ASD) had a 9 times higher risk for non-accidental fractures. The number of non-accidental fractures significantly increased after 2019. CONCLUSIONS: The study findings suggest that nearly 1 out of all 20 fractures in children under age 6 are caused by NAT, and that rib/sternum fractures are most predictive of an inflicted nature. The study also showed a significant increase in the incidence of NAT, during and after the pandemic.

Complications and Health-Related Quality of Life in Children with Various Etiologies of Early-Onset Scoliosis Treated with Magnetically Controlled Growing Rods-A Multicenter Study.

Background: Early-onset scoliosis (EOS) refers to spinal deformities that develop and are diagnosed before the age of 10. The most important goals of the surgical treatment of EOS are to stop the progression of curvature, achieve the best possible correction, preserve motion, and facilitate spinal growth. The objectives of this multicenter study were to analyze the risk of complications among patients with EOS treated using magnetically controlled growing rods (MCGRs) and assess the patients' and their parents' quality of life after diagnosis and treatment with a minimum two-year follow-up. Methods: Patients given an ineffective nonoperative treatment qualified for surgery with MCGRs. This study involved 161 patients (90 females and 71 males) who were classified according to the etiology of curvature. The intraoperative and postoperative complications and those that occurred during the continuation of treatment with MCGRs were recorded and analyzed. The 24-item Early-Onset Scoliosis Questionnaire (EOSQ-24) was used to evaluate the patients' quality of life and satisfaction with the treatment. Results: Implant-related complications requiring instrumentation revision were recorded in 26% of the patients. Medical complications occurred in 45% of the population. The EOSQ-24 revealed a significant improvement in the average scores during the follow-up. Conclusions: The treatment of early-onset scoliosis with MCGRs carries 66% risks of incurring medical and mechanical complications, the latter 26% of patients requiring revision procedures. Children with neuromuscular scoliosis, females, and with curvature greater than 90 degrees are at a higher risk of developing complications. Limiting the number of elective surgeries necessitated to prolong the instrumentation and treatment process for patients with MCGRs can greatly enhance their quality of life and satisfaction throughout the follow-up period.
