ABSTRACT
BACKGROUND: Dog walking is associated with a significant injury burden among adults, but the risk of injury associated with dog walking among children is poorly understood. This study describes the epidemiology of children treated at US emergency departments for injuries related to leash-dependent dog walking. METHODS: The National Electronic Injury Surveillance System (NEISS) database was retrospectively analyzed to identify children (5 to 18 years of age) presenting to US emergency departments between 2001 and 2020 with dog walking-related injuries. Primary outcomes included annual estimates of injury incidence, injury characteristics, and risk factors for fracture or traumatic brain injury (TBI). Weighted estimates, odds ratios (ORs), and 95% confidence intervals (CIs) were generated using NEISS sample weights. RESULTS: An estimated 35,611 children presented to US emergency departments with injuries related to dog walking. The mean age of patients was 11 years, and most patients were girls (63%). Over half (55%) of injuries were orthopaedic, and patients commonly injured their upper extremity (57%) and were hurt while falling when pulled or tripped by the leash (55%). The most frequent injuries were wrist strain/sprain (5.6%), finger strain/sprain (5.4%), and ankle strain/sprain (5.3%). On multivariable analysis, injured children aged 5 to 11 years were more likely to have sustained a TBI (OR: 3.2, 95% CI: 1.1-9.7) or fracture (OR: 1.6; 95% CI: 1.1-2.3). Boys were more likely than girls to have experienced a fracture (OR: 2.0, 95% CI: 1.3-2.5). CONCLUSIONS: Dog walking-related injuries in children are primarily orthopaedic and involve the upper extremity. Younger children and boys are at greater risk for serious dog walking-related injuries. LEVEL OF EVIDENCE: Level III.

PURPOSE: CIC-rearranged sarcomas represent a type of undifferentiated small round cell sarcoma (USRCS) characterized by poor survival, rapid development of chemotherapy resistance, and high rates of metastasis. We aim to contribute to the growing body of knowledge regarding diagnosis, treatment, clinical course, and outcomes for these patients. METHODS: This case series investigates the clinical courses of ten patients with CIC-rearranged sarcoma treated at the Johns Hopkins Hospital from July 2014 through January 2024. Clinical data were retrospectively extracted from electronic medical records. RESULTS: Patients ranged from 10 to 67 years of age at diagnosis, with seven patients presenting with localized disease and three with metastatic disease. Tumors originated from soft tissues of various anatomic locations. Mean overall survival (OS) was 22.1 months (10.6-52.2), and mean progression-free survival (PFS) was 16.7 months (5.3-52.2). Seven patients received intensive systemic therapy with an Ewing sarcoma-directed regimen or a soft tissue sarcoma-directed regimen. Three patients experienced prolonged disease-free survival without systemic treatment. CONCLUSION: Most patients in this case series demonstrated aggressive clinical courses consistent with those previously described in the literature, although we note a spectrum of clinical outcomes not previously reported. The diversity of clinical courses underscores the need for an improved understanding of individual tumor biology to enhance clinical decision-making and patient prognosis. Despite its limitations, this article broadens the spectrum of reported clinical outcomes, providing a valuable addition to the published literature on this rare cancer.

Background: Lisfranc fracture-dislocation is an uncommon but serious injury that currently lacks universal consensus on optimal operative treatment. Two common fixation methods are open reduction and internal fixation (ORIF) and primary arthrodesis (PA). The objective of this study is to analyze the cost difference between ORIF and PA of Lisfranc injuries, along with the contribution of medical services to overall costs. Methods: This was a retrospective cost analysis of the MarketScan database from 2010 to 2020. MarketScan is an insurance and commercial claims database that integrates deidentified patient information. It captures person-specific clinical utilization, expenditures, and enrollment across inpatient and outpatient services. Patients undergoing primary ORIF (CPT code 28615) vs PA (28730 and 28740) for Lisfranc fracture-dislocation were identified. The primary independent variable was ORIF vs PA of Lisfranc injury. Total costs due to operative management was the primary objective. The utilization of and costs contributed by medical services was a secondary outcome. Results: From 2010 to 2020, a total of 7268 patients underwent operative management of Lisfranc injuries, with 5689 (78.3%) ORIF and 1579 (21.7%) PA. PA was independently associated with increased net and total payment and coinsurance, clinic visits, and imaging, and patients attended significantly more PT sessions. Conclusion: Using this large database that does not characterize severity or extent of injury, we found that treatment of Lisfranc fracture-dislocation with ORIF was associated with substantially lower initial episode of treatment costs compared with PA. Specific excessive cost drivers for PA were clinic visits, PT sessions, and imaging. Level of Evidence: Level III, retrospective cohort study.
ABSTRACT
INTRODUCTION: The purpose of this study was to evaluate the ability of the Pathologic Fracture Mortality Index (PFMI) to predict the risk of 30-day morbidity after pathologic fracture fixation and compare its efficacy with those of the American Society of Anesthesiologists (ASA) physical status, modified Charlson Comorbidity Index (mCCI), and modified frailty index (mFI-5). METHODS: Cohorts of 1,723 patients in the American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2020 and 159 patients from a tertiary cancer referral center who underwent fixation for impending or completed pathologic fractures of long bones were retrospectively analyzed. National Surgical Quality Improvement Program morbidity variables were categorized into medical, surgical, utilization, and all-cause. PFMI, ASA, mCCI, and mFI-5 scores were calculated for each patient. Area under the curve (AUC) was used to compare efficacies. RESULTS: AUCs predicting all-cause morbidity were 0.62, 0.54, and 0.56 for the PFMI, ASA, and mFI-5, respectively. The PFMI outperformed the ASA and mFI-5 in predicting all-cause ( P < 0.01), medical ( P = 0.01), and utilization ( P < 0.01) morbidities. In the 2005 to 2012 subset, the PFMI outperformed the ASA, mFI-5, and mCCI in predicting all-cause ( P = 0.01), medical ( P = 0.03), and surgical ( P = 0.05) morbidities but performed similarly to utilization morbidity ( P = 0.19). In our institutional cohort, the AUC for the PFMI in morbidity stratification was 0.68. The PFMI was associated with all-cause (odds ratio [OR], 1.30; 95% confidence interval [CI], 1.12 to 1.51; P < 0.001), medical (OR, 1.19; 95% CI, 1.03 to 1.40; P = 0.046), and utilization (OR, 1.32; 95% CI, 1.14 to 1.52; P < 0.001) morbidities but not significantly associated with surgical morbidity (OR, 1.21; 95% CI, 0.98 to 1.49; P = 0.08) in this cohort. DISCUSSION: The PFMI is an advancement in postoperative morbidity risk stratification of patients with pathologic fracture from metastatic disease. LEVEL OF EVIDENCE: III.

BACKGROUND: Although symptomatic neuroma formation has been described in other patient populations, these data have not been studied in patients undergoing resection of musculoskeletal tumors. This study aimed to characterize the incidence and risk factors of symptomatic neuroma formation following en bloc resection in this population. METHODS: The authors retrospectively reviewed adults undergoing en bloc resections for musculoskeletal tumors at a high-volume sarcoma center from 2014 to 2019. The authors included en bloc resections for an oncologic indication and excluded non-en bloc resections, primary amputations, and patients with insufficient follow-up. Data are provided as descriptive statistics, and multivariable regression modeling was performed. RESULTS: The authors included 231 patients undergoing 331 en bloc resections (female, 46%; mean age, 52 years). Nerve transection was documented in 87 resections (26%). There were 81 symptomatic neuromas (25%) meeting criteria of Tinel sign or pain on examination and neuropathy in the distribution of suspected nerve injury. Factors associated with symptomatic neuroma formation included age 18 to 39 [adjusted OR (aOR), 3.6; 95% CI, 1.5 to 8.4; P < 0.01] and 40 to 64 (aOR, 2.2; 95% CI, 1.1 to 4.6; P = 0.04), multiple resections (aOR, 3.2; 95% CI, 1.7 to 5.9; P < 0.001), preoperative neuromodulator requirement (aOR, 2.7; 95% CI, 1.2 to 6.0; P = 0.01), and resection of fascia or muscle (aOR, 0.5; 95% CI, 0.3 to 1.0; P = 0.045). CONCLUSION: The authors' results highlight the importance of adequate preoperative optimization of pain control and intraoperative prophylaxis for neuroma prevention following en bloc resection of tumors, particularly for younger patients with a recurrent tumor burden. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Background: Pathologic acetabular fracture secondary to skeletal metastasis may result in debilitating pain, inability to ambulate, and impaired quality of life, which may mark the first period of dependent care in cancer patients. Acetabular reconstruction may involve morbid procedures with increased complication rates. This study aimed to evaluate the evolution of pain, performance status, and ambulation following nonoperative management or open reconstruction of pathologic acetabular fractures. Methods: A retrospective cohort of 2630 adult patients with osseous metastatic disease treated at a high-volume cancer center between 2005 and 2021 was screened for pathologic fractures of the acetabulum. The study outcomes were pain, performance status, and the ability to ambulate. We identified 78 patients (median age, 60 years; 37 female patients [46%]) with 81 fractures. Of these, treatment consisted of open reconstruction (n = 34) or nonoperative management alone (n = 47). The mean follow-up in surviving patients was 3.4 years. Results: Open reconstruction was performed more frequently for displaced fractures (P < 0.01), Harrington class III or IV acetabula (P < 0.01), and patients with a performance status ≥3 at hospitalization (P = 0.00). Open reconstruction was associated with clinically meaningful improvements in pain (adjusted odds ratio [aOR], 8.3; 95% CI, 1.4-50.6; P = 0.02) and performance status (aOR, 10.9; 95% CI, 1.7-71.0; P = 0.01) at discharge and a restoration of ambulation (aOR, 7.5; 95% CI, 1.9-29.8; P < 0.01) at final follow-up. Conclusions: In patients with pathologic acetabular fracture due to osseous metastatic disease, functional improvements in pain, performance status, and ambulation were observed following open acetabular reconstruction in carefully selected patients, with no impact on survival, while noninferior improvements were observed in patients receiving nonoperative management when considering their larger clinical context. Level of evidence: Level III, therapeutic study.
ABSTRACT
BACKGROUND: Surgical site infection (SSI) is a major potential complication following pediatric spinal deformity surgery that is associated with significant morbidity and increased costs. Despite this, SSI rates remain high and variable across institutions, in part due to a lack of up-to-date, comprehensive prevention, and treatment protocols. Furthermore, few attempts have been made to review the optimal diagnostic modalities and treatment strategies for SSI following scoliosis surgery. The aim of this study was to systematically review current literature on risk factors for SSI in pediatric patients undergoing scoliosis surgery, as well as strategies for prevention, diagnosis, and treatment. METHODS: On January 19, 2022, a systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies reporting risk factors for acute, deep SSI (<90 d) or strategies for prevention, diagnosis, or treatment of SSI following pediatric scoliosis surgery were included. Each included article was assigned a level of evidence rating based on study design and quality. Extracted findings were organized into risk factors, preventive strategies, diagnostic modalities, and treatment options and each piece of evidence was graded based on quality, quantity, and consistency of underlying data. RESULTS: A total of 77 studies met the inclusion criteria and were included in this systematic review, of which 2 were categorized as Level I, 3 as Level II, 64 as Level III, and 8 as Level IV. From these studies, a total of 29 pieces of evidence (grade C or higher) regarding SSI risk factors, prevention, diagnosis, or treatment were synthesized. CONCLUSIONS: We present an updated review of published evidence for defining high-risk patients and preventing, diagnosing, and treating SSI after pediatric scoliosis surgery. The collated evidence presented herein may help limit variability in practice and decrease the incidence of SSI in pediatric spine surgery. LEVEL OF EVIDENCE: Level III-systematic review.

PURPOSE: Dog walking is a popular daily activity, yet information regarding its injury burden is limited. This study describes the epidemiology of injuries related to leash-dependent dog walking among adults presenting to US emergency departments from 2001 to 2020. METHODS: A retrospective analysis was performed using the National Electronic Injury Surveillance System database to identify adults (≥18 yr) presenting to US emergency departments with leash-dependent dog walking-related injuries between 2001 and 2020. Outcomes included annual estimates of injury incidence, injury characteristics, and risk factors for sustaining a fracture or traumatic brain injury (TBI). Weighted estimates and 95% confidence intervals (CI) were generated using National Electronic Injury Surveillance System sample weights. RESULTS: Between 2001 and 2020, an estimated 422,659 adults presented to US emergency departments with injuries related to leash-dependent dog walking. The annual incidence increased more than fourfold during this period ( n = 7282 vs n = 32,306, P < 0.001). Most patients were women (75%) and adults age 40 to 64 yr (47%), with a mean age of 53 ± 0.5 yr. Patients commonly injured their upper extremity (51%) and were injured while falling when pulled or tripped by the leash (55%). The three most common injuries were finger fracture (6.9%), TBI (5.6%), and shoulder sprain/strain (5.1%). On multivariate analysis, fracture risk among dog walkers was higher in adults age ≥65 yr (odds ratio [OR], 2.1; 95% CI, 1.8-2.5) and women (OR, 1.5; 95% CI, 1.3-1.7). Risk of TBI was also elevated among older dog walkers (OR, 1.6; 95% CI, 1.3-2.0). CONCLUSIONS: Dog walking is associated with a considerable and rising injury burden. Dog owners should be informed of this injury potential and advised on risk-reduction strategies.
ABSTRACT
CASE: We present a 23-year-old man with acute-on-chronic shoulder pain with an aggressive-appearing, destructive lesion of the left proximal humerus and diffuse lung metastases. Biopsy revealed conventional giant cell tumor of bone (GCTB) without sarcomatous differentiation, treated with resection and proximal humerus reconstruction. Without systemic treatment, his pulmonary metastases demonstrated modest spontaneous regression, with no impairment of pulmonary function. CONCLUSIONS: Although GCTB is known to metastasize to lungs, these deposits most commonly follow local recurrence. We describe a young adult with diffuse pulmonary nodules at initial presentation, although still following an indolent clinical course without the need for additional systemic therapy.

The purpose of this study was to assess the influence of the COVID-19 pandemic on the 2021 orthopaedic surgery residency match outcomes. Because in-person away rotations and interviews were canceled during the 2020 to 2021 application cycle, we hypothesized that applicants would match at their home program at a higher rate in 2021 than in previous years. Methods: We queried allopathic orthopaedic surgery residency websites and social media accounts for names of residents and medical school information for cohorts matching from 2017 through 2021. To assess availability of and participation in virtual away rotations, we administered a survey to Accreditation Council for Graduate Medical Education-accredited allopathic orthopaedic surgery residency programs. The primary outcome was the annual proportion of applicants matching at the program affiliated with their medical school ("home program"). Subgroup analyses were stratified by Doximity reputation ranking and availability of a virtual away rotation. Results: We identified 2,632 residents who matched between 2017 and 2020 and 698 residents who matched in 2021. Overall home program match rate and likelihood of home matching were higher in 2021 compared with 2017 to 2020 (28% vs. 20%; odds ratio [OR] = 1.51, 95% confidence interval [CI] 1.24-1.82, p < 0.001). The increase in the home match rate at programs ranked in the top 30 (27% vs. 20%, p = 0.034) was similar to the increase at programs ranked outside the top 30 (28% vs. 20%, p < 0.001). Of the 66 (48%) programs that responded to the survey, 16 (24%) offered a virtual away rotation. Programs with a higher Doximity ranking were more likely than lower-ranked programs to offer a virtual away rotation (OR = 6.75, 95% CI 1.95-23.4, p = 0.003). Home match rates did not differ significantly between programs that offered a virtual away rotation and those that did not (26% vs. 32%, p = 0.271). Conclusions: A higher proportion of orthopaedic surgery residency applicants matched at their home program in 2021 compared with previous years. Limitations on in-person activities due to the COVID-19 pandemic may have contributed to this rise. Level of Evidence: N/A.
ABSTRACT
BACKGROUND: Prior "best practice guidelines" (BPG) have identified strategies to reduce the risk of acute deep surgical site infection (SSI), but there still exists large variability in practice. Further, there is still no consensus on which patients are "high risk" for SSI and how SSI should be diagnosed or treated in pediatric spine surgery. We sought to develop an updated, consensus-based BPG informed by available literature and expert opinion on defining high-SSI risk in pediatric spine surgery and on prevention, diagnosis, and treatment of SSI in this high-risk population. MATERIALS AND METHODS: After a systematic review of the literature, an expert panel of 21 pediatric spine surgeons was selected from the Harms Study Group based on extensive experience in the field of pediatric spine surgery. Using the Delphi process and iterative survey rounds, the expert panel was surveyed for current practices, presented with the systematic review, given the opportunity to voice opinions through a live discussion session and asked to vote regarding preferences privately. Two survey rounds were conducted electronically, after which a live conference was held to present and discuss results. A final electronic survey was then conducted for final voting. Agreement ≥70% was considered consensus. Items near consensus were revised if feasible to achieve consensus in subsequent surveys. RESULTS: Consensus was reached for 17 items for defining high-SSI risk, 17 items for preventing, 6 for diagnosing, and 9 for treating SSI in this high-risk population. After final voting, all 21 experts agreed to the publication and implementation of these items in their practice. CONCLUSIONS: We present a set of updated consensus-based BPGs for defining high-risk and preventing, diagnosing, and treating SSI in high-risk pediatric spine surgery. We believe that this BPG can limit variability in practice and decrease the incidence of SSI in pediatric spine surgery. LEVEL OF EVIDENCE: Not applicable.

BACKGROUND: Pain management after foot and ankle surgery must surmount unique challenges that are not present in orthopaedic surgery performed on other parts of the body. However, disparate and inconsistent evidence makes it difficult to draw meaningful conclusions from individual studies. QUESTIONS/PURPOSES: In this systematic review, we asked: what are (1) the patterns of opioid use or prescription (quantity, duration, incidence of persistent use), (2) factors associated with increased or decreased risk of persistent opioid use, and (3) the clinical outcomes (principally pain relief and adverse events) associated with opioid use in patients undergoing foot or ankle fracture surgery? METHODS: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for our review. We searched PubMed, Embase, Scopus, Cochrane, and Web of Science on October 15, 2021. We included studies published from 2010 to 2021 that assessed patterns of opioid use, factors associated with increased or decreased opioid use, and other outcomes associated with opioid use after foot or ankle fracture surgery (principally pain relief and adverse events). We excluded studies on pediatric populations and studies focused on acute postoperative pain where short-term opioid use (< 1 week) was a secondary outcome only. A total of 1713 articles were assessed and 18 were included. The quality of the 16 included retrospective observational studies and two randomized trials was evaluated using the Methodological Index for Non-Randomized Studies criteria and the Jadad scale, respectively; study quality was determined to be low to moderate for observational studies and good for randomized trials. Mean patient age ranged from 42 to 53 years. Fractures studied included unimalleolar, bimalleolar, trimalleolar, and pilon fractures. RESULTS: Proportions of postoperative persistent opioid use (defined as use beyond 3 or 6 months postoperatively) ranged from 2.6% (546 of 20,992) to 18.5% (32 of 173) and reached 39% (28 of 72) when including patients with prior opioid use. Among the numerous associations reported by observational studies, two or more preoperative opioid prescriptions had the strongest overall association with increased opioid use, but this was assessed by only one study (OR 11.92 [95% confidence interval (CI) 9.16 to 13.30]; p < 0.001). Meanwhile, spinal and regional anesthesia (-13.5 to -41.1 oral morphine equivalents (OME) difference; all p < 0.01) and postoperative ketorolac use (40 OME difference; p = 0.037) were associated with decreased opioid consumption in two observational studies and a randomized trial, respectively. Three observational studies found that opioid use preoperatively was associated with a higher proportion of emergency department visits and readmission (OR 1.41 to 17.4; all p < 0.001), and opioid use at 2 weeks postoperatively was associated with slightly higher pain scores compared with nonopioid regimens (ß = 0.042; p < 0.001 and Likert scale 2.5 versus 1.6; p < 0.05) in one study. CONCLUSION: Even after noting possible inflation of the harms of opioids in this review, our findings nonetheless highlight the need for opioid prescription guidelines specific for foot and ankle surgery. In this context, surgeons should utilize short (< 1 week) opioid prescriptions, regional anesthesia, and multimodal pain management techniques, especially in patients at increased risk of prolonged opioid use. LEVEL OF EVIDENCE: Level III, therapeutic study.

BACKGROUND: Juvenile idiopathic arthritis (JIA) is an inflammatory arthropathy with onset in children younger than 16 years. Treatment is primarily medical; however, surgical interventions, such as arthroscopic or open synovectomy, can be beneficial. Many studies have investigated synovectomy in JIA, but the results of these studies have not been synthesized to our knowledge. Therefore, we performed a systematic review of the literature reporting synovectomy as a treatment for JIA to provide clinical recommendations regarding its risks and benefits. METHODS: On March 8, 2022, we searched the Cochrane Library, Embase, PubMed, Scopus, and Web of Science for studies evaluating clinical outcomes of open or arthroscopic synovectomy to treat JIA in patients younger than 18 years. We included only studies published in English and excluded studies of synovectomy to treat other arthropathies, septic arthritis, hemophilia, or foreign body arthropathy. The level of evidence for included studies was determined by using the Oxford Centre for Evidence-Based Medicine criteria. We qualitatively analyzed clinical outcomes data, including patient-reported pain relief, rates of symptom recurrence, and postoperative complications. RESULTS: Of 428 articles assessed, 14 were included in our analysis. One was a randomized trial, 1 was a case-control study, and all others were case-series. Studies consistently reported that synovectomy was associated with improved function and decreased pain postoperatively. However, comparisons with modern medical therapy were lacking. Rates of arthritis recurrence varied, with increasing symptom recurrence with longer follow-up and re-synovectomy rates up to 15%. Oligoarticular disease and early disease course were associated with better response to synovectomy, whereas systemic and polyarticular disease were associated with poor response. Stiffness requiring manipulation under anesthesia was the most common complication (4% of all included patients). CONCLUSION: Although synovectomy is associated with positive functional outcomes and pain reduction postoperatively, there was inadequate comparison thus inadequate evidence to recommend it over modern medical therapy. The current literature suggests that synovectomy should be offered only to patients for whom medical management has failed, while noting the risks of decreased range of motion and symptom recurrence over time.
