RESUMO

BACKGROUND: Surgical outreach to low- and middle-income countries (LMICs) by organizations from high- income countries is on the rise to help address the growing burden of conditions warranting surgery. However, concerns remain about the impact and sustainability of such outreach. Leading organizations (e.g., the World Health Organization) advocate for a capacity-building approach to ensure the safety, quality, and sustainability of the local health-care system. Despite this, to our knowledge, no guidelines exist to inform such efforts. We aimed to develop clinical practice guidelines (CPGs) to support capacity-building in orthopaedic surgical outreach utilizing a multistakeholder and international voting panel. METHODS: We followed a modified American Academy of Orthopaedic Surgeons (AAOS) CPG development process. We systematically reviewed the existing literature across 7 predefined capacity-building domains (partnership, professional development, governance, community impact, finance, coordination, and culture). A writing panel composed of 6 orthopaedic surgeons with extensive experience in surgical outreach reviewed the existing literature and developed a consensus-based CPG for each domain. We created an international voting panel of orthopaedic surgeons and administrators who have leadership roles in outreach organizations or hospitals with which outreach organizations partner. Members individually reviewed the CPGs and voted to approve or disapprove each guideline. A CPG was considered approved if >80% of panel members voted to approve it. RESULTS: An international voting panel of 14 surgeons and administrators from 6 countries approved all 7 of the CPGs. Each CPG provides recommendations for capacity-building in a specific domain. For example, in the domain of partnership, the CPG recommends the development of a documented plan for ongoing, bidirectional partnership between the outreach organization and the local team. In the domain of professional development, the CPG recommends the development of a needs-based curriculum focused on both surgical and nonsurgical patient care utilizing didactic and hands-on techniques. CONCLUSIONS: As orthopaedic surgical outreach grows, best-practice CPGs to inform capacity-building initiatives can help to ensure that resources and efforts are optimized to support the sustainability of care delivery at local sites. These guidelines can be reviewed and updated in the future as evidence that supports capacity-building in LMICs evolves.The global burden of disease warranting surgery is substantial, and morbidity and mortality from otherwise treatable conditions remain disproportionately high in low- and middle-income countries (LMICs)1,2. It is estimated that up to 2 million (about 40%) of injury-related deaths in LMICs could be avoided annually if mortality rates were reduced to the level of those in high-income countries (HICs)3. Despite this, progress toward improved access to safe, timely surgery in resource-poor areas has been slow. Historically, nongovernmental organizations (NGOs) have tried to address unmet surgical needs through short-term outreach trips; however, growing criticism has highlighted the limitations of short-term trips, including limited follow-up, an increased burden on the local workforce, and further depletion of local resources4-6. In light of ongoing concerns, public health priorities have shifted toward models that emphasize long-term capacity-building rather than short-term care delivery. Capacity-building is an approach to health-care development that builds independence through infrastructure development, sustainability, and enhanced problem-solving while taking context into account7,8.

RESUMO

Orthopaedic surgery has not experienced the same increase in diversity as other surgical subspecialties over time. Professional orthopaedic societies across the nation, including the American Academy of Orthopaedic Surgeons, are now making sincere efforts to improve diversity, equity, and inclusion (DEI) within the field. Several national groups provide funding to support DEI -related research as well as scholarships to national meetings. Others are more focused on mentorship and mitigation of residency attrition amongst underrepresented minorities (URMs). Individual residency programs, including the Department of Orthopaedics at Brown University, are engaging in community outreach to attract more diverse candidates to orthopaedics and providing away rotation scholarship support for medical students that identify as female or URMs. These local and national efforts will hopefully lead to a more inclusive environment for all trainees and practitioners within orthopaedics and ultimately improved orthopaedic care for all patients.

RESUMO

PURPOSE: Previous studies evaluating weight bearing of distal radius fractures treated through dorsal spanning bridge plates used extra-articular fracture models, and have not evaluated the role of supplementary fixation. We hypothesized that supplementary fixation with a spanning dorsal bridge plate for an intra-articular wrist fracture would decrease the displacement of individual articular pieces with cyclic axial loading and allow for walker or crutch weight bearing. METHODS: Thirty cadaveric forearms were matched into 3 cohorts, controlling for age, sex, and bone mineral density. An intra-articular fracture model was fixed with the following 3 techniques: (1) cohort A with a dorsal bridge plate, (2) cohort B with a dorsal bridge plate and two 1.6-mm k-wires, and (3) cohort C with a dorsal bridge plate and a radial pin plate. Specimens were axially loaded cyclically with escalating weights consistent with walker and crutch weight-bearing with failure defined as 2-mm displacement. RESULTS: No specimens failed at 2- or 5-kg weights, but cohort A had significantly more displacement at these weights compared with cohort B. Cohort A had significantly more failure than cohort C. Both cohort A and cohort B had significantly more displacement at crutch weight bearing compared with cohort C. The supplementary fixation group had significantly lower displacement at crutch weight-bearing compared with cohort A in all gaps. Survival curves demonstrated the fixation cohort to survive higher loads than the nonfixation group. CONCLUSION: There was significantly less displacement and less failure of intra-articular distal radius fractures treated with a spanning dorsal bridge plate and supplementary fixation. Our model showed that either type of fixation was superior to the nonfixation group. CLINICAL SIGNIFICANCE: When considering early weight-bearing for intra-articular distal radius fractures treated with a spanning dorsal bridge plate, supplementary fixation may be considered as an augmentation to prevent fracture displacement.

RESUMO

BACKGROUND: This study seeks to examine the reliability, quality, and content of YouTube videos on cubital tunnel syndrome, on which there is presently a paucity of information. METHODS: The top 50 unique YouTube videos by relevance resulting from the Boolean search term "cubital tunnel + cubital tunnel syndrome" were identified, with video properties for analysis including source, upload date, duration, views, and comments. Content was assessed using the Journal of American Medical Association (JAMA) criteria, the Global Quality Score (GQS), and a "Cubital Tunnel-Specific Score" (CTSS). RESULTS: The average video saw 72 108 ± 199 362 views, with videos produced by allied (nonphysician) health professionals demonstrating the highest mean views (111 789 ± 294 471 views). Videos demonstrated low mean JAMA scores (2.4/4 ± 0.7), GQS (2.8/5 ± 1.3), and CTSS (7.5/21 ± 4.3), with academic and nonacademic physician videos demonstrating significantly greater mean GQS and CTSS scores when compared with videos by allied health professionals. Positive independent predictors for GQS included academic sources (ß = 1.871), nonacademic physician sources (ß = 1.651), and video duration (ß = 0.102), which were likewise positive predictors for CTSS (ß = 4.553, 4.639, 0.374). Content relating to surgical techniques or approaches for cubital tunnel decompression had the greatest CTSS scores (11.2 [4.2]). CONCLUSIONS: YouTube is a source of highly accessible information on cubital tunnel syndrome, although the average video presents generally poor and inadequate information. Directing patients toward higher quality video resources can be a meaningful component of patient education.

RESUMO

Rising health care costs in the United States, besides evolving payment models that place emphasis on value instead of volume, have led to an increasing number of studies evaluating hand surgery from an economic perspective. To better understand such economics-based studies, this review provides a foundational understanding of what value entails by defining its features of quality and cost. Principles of evaluating value through cost-benefit, cost-effectiveness, and cost-utility analyses are discussed. Models of discounting and clinical decision analyses are also discussed. Understanding such concepts and their evaluation in economic analyses will provide greater insight into the economic landscape of hand surgery and improving patient care.

RESUMO

BACKGROUND: Psychiatric comorbidities have been shown to influence outcomes of various orthopedic pathologies. This study aimed to compare rates of delayed scaphoid union and surgical intervention for fractures in patients with and without comorbid psychiatric diagnoses. METHODS: A matched retrospective cohort study was performed using the PearlDiver database to determine the association of depression, anxiety, bipolar disorder, and schizophrenia with delayed union rates within 3 and 6 months and rates of nonacute surgical intervention (fixation or grafting) within 6 and 12 months of scaphoid fracture. Analyses were completed using multivariate logistic regression. RESULTS: Among 20 340 patients, a comorbid psychiatric diagnosis was associated with increased rates of delayed scaphoid union at 3 months (odds ratio [OR] = 1.29; 95% confidence interval [CI], 1.14-1.45) and 6 months (OR = 1.23; 95% CI, 1.10-1.38). At 3 months, women with any psychiatric disorder (OR = 1.58; 1.29-1.66), depression (OR = 1.68; 1.31-2.17), and schizophrenia (OR = 5.32; 95% CI, 1.06-26.79) were more likely to experience delayed union, with similar results at 6 months. Men with bipolar disorder experienced increased delayed union rates at 6 months (OR = 1.40; 1.03-1.91). A comorbid psychiatric diagnosis (OR = 1.10; 1.01-1.20) was associated with increased rates of surgical intervention, whereas schizophrenia was associated with decreased rates (OR = 0.58; 0.34-0.99). CONCLUSION: Patients with comorbid psychiatric conditions experienced increased rates of delayed scaphoid union. These results underscore the importance of understanding factors that may place patients at risk of impaired recovery.

RESUMO

Background Scaphoid fracture is the most common carpal bone fracture. Open reduction internal fixation of scaphoid fractures typically undergo stabilization by a single headless compression screw (HCS). During screw insertion, a derotational Kirschner wire (K-wire) is often placed for rotational control of the near and far fragment. Questions/Purposes The aim of this study was to determine if there is an angle of derotational K-wire placement in relation to the axis of a HCS that compromises the amount of compression generated at a fracture site by the HCS. We hypothesize that increased off-axis angle will lead to decreased compression across the fracture site. Methods A Cellular Block 20 rigid polyurethane foam (Sawbones, Vashon, WA) scaphoid model was created to eliminate variability in bone mineral density in cadaveric bone. MiniAcutrak HCS screws (Acumed, Hillsboro, OR) were used for testing. Three conditions were tested: (1) HCS with derotational wire inserted parallel to the HCS (zero degrees off-axis); (2) HCS with derotational wire inserted 10 degrees off-axis; and (3) HCS with derotational wire inserted 20 degrees off-axis. Results A statistically significant difference in the mean compression of the control group (56.9 N) was found between the mean compression with the derotational K-wire placed 20 degrees off-axis (15.2 N) ( p = 0.001). Conclusions Compression at the fracture site could be impeded by placing an excessively angulated off-axis derotation wire prior to insertion of the HCS. Clinical Relevance Our study adds a new detail to the optimal technique of HCS placement in scaphoid fractures to improve compression and fracture union.

RESUMO

BACKGROUND: Hand fractures are among the most common injuries presenting in pediatric emergency departments (EDs) with incidence reported as high as 624 hand fractures per 100,000 person-years. If gone untreated, these injuries can lead to pain, loss of function, and psychological trauma. The purpose of this study was to identify risk factors and characterize pediatric hand fractures over a 5-year period. METHODS: The National Electronic Injury Surveillance System (NEISS) was queried for all hand fractures in patients aged 1 to 19 years presenting to US EDs between 2016 and 2020. Incidence was calculated using US census data. Cases were retrospectively analyzed using age, location of the injury, sex, coronavirus disease-2019 (COVID-19) era, and etiology of injury. Bivariate logistic regression was used where appropriate. RESULTS: A total of 21,031 pediatric hand fractures were identified, representing an estimated 565,833 pediatric hand fractures presenting to EDs between 2016 and 2020. The mean incidence of pediatric hand fractures was 138.3 fractures for 100,000 person-years [95% confidence interval (CI): 136.2-140.4], with a 39.2% decrease in incidence occurring between 2019 and 2020. It was found that 42.2% of the fractures were in patients aged 10 to 14. The incidence of hand fractures for males and females was 97.9 (95% CI: 96.2-99.7) and 40.4 (95% CI: 39.2-41.5), respectively, with the male rate peaking at age 14 and the female rate peaking at age 12. Age, sex, location of the injury, and injury during the COVID-19 pandemic were demonstrated to influence the frequency and etiology of the fracture. CONCLUSION: This study determined the incidence of pediatric hand fractures presenting to EDs across the United States. In addition, it identified risk factors for common hand fracture etiologies (sports-related, falling, crush, punching) and demonstrated the change in rates of different etiologies of pediatric hand fractures that presented to US EDs during the COVID-19 pandemic. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

RESUMO

Juxtaphyseal fractures of the distal phalanges of upper extremity digits are most commonly of the Salter-Harris II variety and occur most commonly in the thumb. The diagnosis of this injury is essential as it may present as an open fracture with a nailbed injury ("Seymour fracture"). However, an intra-articular, epiphyseal fracture may also occur and mimic a mallet deformity or Seymour fracture. Prompt diagnosis is essential to rule out an open fracture and obtain anatomical alignment and stability to attempt to reduce complications such as physeal arrest. Here, we present a patient with a displaced Salter-Harris type III fracture of his thumb distal phalanx and review his management and early-term outcome. We present this case to bring attention to this rare and unique injury, review the available literature, and discuss management and outcomes.

RESUMO

Background: There is a paucity of literature exploring the epidemiology of finger infections presenting to emergency departments (EDs) on a national scale. The purpose of this study was to determine the national incidence of and risk factors for finger infections. Methods: Finger infections presenting to EDs between 2012 and 2016 were identified in the National Electronic Injury Surveillance System database. Finger infections were characterized by mechanism and type, with subanalyses for sex, race, and age. Results: Over this 5-year period, finger infections accounted for 80 519 visits to EDs in the United States. The annual incidence increased significantly from 4.4 per 100 000 person-years in 2012 to 6.2 in 2016. The 3 most common causes of finger infections were nail manicuring tools, knives, and doors. The most common diagnosis was finger cellulitis (46.3%). Significantly more men developed finger infections than women (relative risk of 1.4). The highest overall incidence was observed in 40- to 59-year-old men (7.8 per 100 000 person-years). Tenosynovitis resulted in the largest proportion of admissions (25%). Conclusions: We have demonstrated a rising incidence of finger infections presenting to EDs, with 40- to 59-year-old patients most at risk. The most common mechanism was the use of nail manicuring tools, such as nail clippers. Patient education may decrease finger infection incidence from these activities, and early detection of finger infections may be crucial to minimizing hospital admissions and invasive treatments.

RESUMO

Background: Traumatic digit amputations are common hand injuries in the United States. The primary aim of our study was to describe the relationship between season and mechanisms of amputation. Methods: The Emergency Department and Orthopaedic Surgery Billing Department databases of our level І institution in the Northeast were reviewed to identify patients with a traumatic digit amputation between January 2010 and December 2015. Inclusion criteria were defined as any patient presenting with a partial or complete amputation through Verdan zone I or II. All patient information was entered into a secure database, including date of injury, demographic information, digits amputated, mechanism of injury (crush, laceration, avulsion, bite, blast, saw, snow blower, or lawn mower), and Verdan zones of amputation. In addition to descriptive statistics, Fisher exact and χ2 tests were used to compare the incidence of these traumatic digit amputation mechanisms between seasons. Results: For this 6-year period, an average of 24 patients presented each season for treatment of a traumatic digit amputation. Of all seasons, spring had the highest proportion of lawn mower amputations (62.5%; P < .0001), summer had the highest proportion of blast amputations (75.0%; P = .011), and winter had the highest proportion of snow blower amputations (90.9%; P < .0001). All other traumatic digit amputation mechanisms had no significant seasonal variation in incidence (P > .30). Conclusions: Given that certain traumatic digit amputation mechanisms occur predictably during certain seasons, seasonal public education has the potential to prevent these debilitating injuries.

RESUMO

Background: Indications for replantation following traumatic digit amputations are more liberal in the pediatric population than in adults, but delineation of patient selection within pediatrics and their outcomes have yet to be elucidated. This study uses a national pediatric database to evaluate patient characteristics and injury patterns involved in replantation and their outcomes. Methods: The Healthcare Cost and Utilization Project Kid's Inpatient Database was queried for traumatic amputations of the thumb and finger from 2000 to 2012. Participants were separated into those who underwent replantation and those who underwent amputation. Patients undergoing replantation were further divided into those requiring revision amputation and/or microvascular revision. Patient age, sex, insurance, digit(s) affected, charges, length of stay, and complications were extracted for each patient. Results: Traumatic digit amputations occurred in 3090 patients, with 1950 (63.1%) undergoing revision amputation and 1140 (36.9%) undergoing replantation. Younger patients, those with thumb injuries, females, and those covered under private insurance were significantly more likely to undergo replantation. Cost, length of stay, and in-hospital complications were significantly greater in replantation patients than in those who had undergone amputation. Following replantation, 237 patients (20.8%) underwent revision amputation and 209 (18.3%) underwent vascular revision, after which 58 required revision amputation. Risk of revision following replantation involved older patients, males, and procedures done recently. Conclusions: Pediatric patients who underwent replantation were significantly younger, female, had thumb injuries, and were covered by private insurance. Our findings demonstrate that in addition to injury factors, demographics play a significant role in the decision for finger replantation and its outcomes.

RESUMO

Background: The purpose of this study is to describe three radiographic stress tests that could be used to examine for distal radioulnar joint (DRUJ) instability intraoperatively, and to determine their ability to detect DRUJ instability after sequentially sectioning the DRUJ. Methods: Eleven fresh frozen cadaveric upper extremities (mean age 52.6 ± 14.9 years) were obtained. We sequentially sectioned the DRUJ. After each component of the DRUJ was sectioned, we performed three radiographic stress tests-squeeze test, ulnar pull in coronal plane, and simulated DRUJ ballotment test. Results: The squeeze test detected a significant increase in diastasis relative to the intact DRUJ after sectioning of the foveal insertion of the triangular fibrocartilage complex (TFCC; 1.0 mm) and the distal oblique bundle (DOB; 1.2 mm). The ulnar pull test in the coronal plane detected a significant increase in diastasis relative to the intact DRUJ after sectioning of the dorsal and volar radioulnar ligaments (2 mm), the foveal insertion of the TFCC (2.6 mm), and the DOB (4.4 mm). The simulated DRUJ ballotment test detected a significant increase in dorsal translation of the ulna relative to the intact DRUJ with sectioning of the foveal insertion of the TFCC (4.9 mm) and the DOB (5.6 mm). Conclusion: The squeeze test and simulated DRUJ ballotment test detect a significant increase in diastasis after the foveal attachment of the TFCC was sectioned. The ulnar pull test in the coronal plane was the most sensitive test for detecting a significant increase in diastasis relative to the intact DRUJ.

RESUMO

BACKGROUND: The American Academy of Orthopaedic Surgeons has adopted the strategic goal of evolving its culture and governance to become more strategic, innovative, and diverse. Given the charge to increase diversity, a focus on assessing and increasing diversity at the faculty level may help this cause. However, an analysis of gender and racial diversity among orthopaedic faculty has not been performed. The purpose of this study was to evaluate faculty appointments for underrepresented minority (URM) and female orthopaedic surgeons. We also aim to draw comparisons between orthopaedic surgery and other specialties. METHODS: Data on gender, race, and faculty rank (clinical instructor, assistant professor, associate professor, and professor) of academic faculty for 18 specialties from 1997 to 2017 were obtained from the Association of American Medical Colleges (AAMC) Faculty Roster. Assistant professors were designated as junior faculty, whereas associate professor and professor were considered senior faculty. URMs were defined using the AAMC definition-groups having lower representation than in the general population. Regression analysis was used to evaluate and compare the change over time and to compare the change across different specialties. RESULTS: Over the 20-year study period, the number of female faculty increased (8.8% pts) but represents a lower proportion than other specialties (13.9% pts) (p = 0.029). Female orthopaedic senior faculty grew slower (7.3% pts) than other specialties (14.7% pts) (p < 0.001). There was no difference in the growth of URM faculty positions (2.0% pts) compared with all other specialties (2.4% pts) (p = 0.165). The proportion of orthopaedic URM senior faculty increased less (0.5% pts) than other specialties (2.5% pts) (p < 0.001), whereas more orthopaedic URM junior faculty were added than other specialties (2.2% pts) (p = 0.012). CONCLUSIONS: Although orthopaedic surgery has increased the representation of female and URM faculty members, it continues to lag behind other specialties. In addition, fewer female and URM orthopaedic faculty members obtained senior faculty status than other specialties. To address the differences seen in faculty diversity, a concerted effort should be made to recruit and promote more diverse faculty, given similar qualifications and capabilities. LEVEL OF EVIDENCE: Prognostic Level IV.

RESUMO

STUDY DESIGN: Basic research (biomechanics). INTRODUCTION: The high degree of motion that occurs at the thumb metacarpophalangeal (MCP) joint must be taken into account when immobilizing a partially torn or repaired thumb ulnar collateral ligament. PURPOSE OF THE STUDY: To determine the efficacy of a radial-based thumb MCP-stabilizing orthosis in resisting abduction across the thumb ulnar collateral ligament. METHODS: Ten fresh cadaveric hands were mounted to a custom board. An anteroposterior radiograph of the thumb was obtained with a 2 N preload valgus force applied to the thumb, and the angle between the Kirschner wires was measured as a baseline. Subsequently, 20, 40, 60, 80, and 100 N valgus forces were applied 15 mm distal to the MCP joint. Anteroposterior radiographs of the thumb were obtained after each force was applied. The angle of displacement between the wires was measured and compared with the baseline angle. The angles were measured with an imaging processing tool. A custom radial-based thumb MCP-stabilizing orthosis was fashioned for each cadaveric thumb by a certified hand therapist. The aforementioned loading protocol was then repeated. RESULTS: The radial-based thumb MCP-stabilizing orthosis significantly reduced mean abduction angles at each applied load. DISCUSSION: We found that our orthosis, despite being hand-based and leaving the thumb IP and CMC joints free, significantly reduced mean abduction angles at each applied load. CONCLUSIONS: This investigation provides objective evidence that our radial-based thumb MCP-stabilizing orthosis effectively reduces the degree of abduction that occurs at the thumb MCP joint up to at least 100 N. LEVEL OF EVIDENCE: n/a (cadaveric).

RESUMO

PURPOSE: Primary revision amputation is the most common treatment method for traumatic digit amputations in the United States. Few studies have reported secondary revision rates after primary revision amputation. The primary aim of our study was to identify risk factors for secondary revision within 1 year of the index procedure. Secondarily, we describe the incidence and timing of complications requiring secondary revision. METHODS: Our institution's emergency department (ED) database was reviewed for traumatic digit amputations over a 6-year period. Patients were reviewed for demographic characteristics, comorbidities, site of treatment (ED versus operating room), and complications requiring secondary revision. Conditional Cox Proportional Hazard regression was used to model hazard of revision within 1 year of index procedure relative to site of initial management, mechanism of injury, injury characteristics, and patient demographics. RESULTS: Five hundred and thirty-seven patients with 677 digits were managed with primary revision amputation. Five hundred and eighty-six digits (86.6%) were revised in the ED, and 91 (13.4%) in the operating room. Ninety-one digits required secondary revision, including 83 within 1 year. No increased risk of secondary revision amputation within 1 year of the index procedure was observed for patients treated in the ED compared with the operating room. Relative to crush injuries, bite and sharp laceration amputations had 4.8 times and 2.6 times increased risk of secondary revision, respectively. The index finger had a 5.3-fold increased risk of revision with the thumb as the reference digit. Work-related injuries had a 1.9-fold increased risk of secondary revision compared with non-work-related injuries. CONCLUSIONS: No evidence was found indicating that traumatic digit amputations primarily revised in the ED had an increased risk of secondary revision. Patients may be counseled on the risk of secondary procedures based on the mechanism of injury, injury characteristics and demographics, as well as the timing of complications.

RESUMO

Surgical site infections remain a dreaded complication of orthopaedic surgery, affecting both patient economics and quality of life. It is important to note that infections are multifactorial, involving both surgical and patient factors. To decrease the occurrence of infections, surgeons frequently use local modalities, such as methicillin-resistant Staphylococcus aureus screening; preoperative bathing; intraoperative povidone-iodine lavage; and application of vancomycin powder, silver-impregnated dressings, and incisional negative-pressure wound therapy. These modalities can be applied individually or in concert to reduce the incidence of surgical site infections. Despite their frequent use, however, these interventions have limited support in the literature.

RESUMO

There are a wide variety of benign and malignant soft tissue tumors. Digital superficial acral fibromyxoma is a rare, benign, expansive soft tissue growth which often involves the distal aspect of the digit and the nail plate. While it is often asymptomatic in nature, it may cause a great deal of distress due to involvement of the nail and the resultant cosmetic deformity. Unlike wide excision or amputation needed for more aggressive tumor types, local excision is often curative. We review the literature and describe the presentation of this unique pathology to our clinic in an otherwise healthy 33-year-old female.
