Cost Analyses of Prosthetic Devices: A Systematic Review.

OBJECTIVE: To synthesize extant literature on the cost-effectiveness of prosthetic interventions and explore applicability to low- and middle-income country (LMIC) settings. DATA SOURCES: A systematic literature review using subject headings including "prosthetics," "amputation," and "cost analysis" was performed with PubMed, Embase, and Web of Science search engines, yielding 1194 articles. An additional 22 articles were identified via backward citation searching for 1144 total after duplicate removal. The search was last run in May of 2019. STUDY SELECTION: Studies were included if they conducted an economic analysis of an upper or lower extremity prosthetic device. Studies were excluded if (1) full text was unavailable in English; (2) study was a systematic review or meta-analysis; or (3) study did not have a prosthetic comparison group. Using DistillerSR software, 2 authors independently conducted title and abstract screening. One author conducted full-text screening. The proportion of initially identified studies that met final inclusion criteria was 1% (12 of 1144). DATA EXTRACTION: Data were dually extracted by 2 authors and reviewed by 3 additional authors. DATA SYNTHESIS: All included studies (N=12) examined lower extremity amputations comparing advanced technology. No studies were conducted in LMICs. Comparable data between studies demonstrated (1) the cost-effectiveness of microprocessor- over nonmicroprocessor-controlled knees for transfemoral amputation in high-income settings; (2) equivocal findings regarding osseointegrated vs socket-suspended prostheses; and (3) increased cost for ICEX and modular socket systems over patellar tendon-bearing socket systems with no functional improvement. CONCLUSIONS: There are few prosthetic cost analyses in the literature. Additional analyses are needed to determine the direct and indirect costs associated with prosthetic acquisition, fitting, and maintenance; the costs of amputee rehabilitation; and long-term economic and quality-of-life benefits. Such studies may guide future prosthetic and rehabilitative care, especially in resource-austere settings where prosthetic needs are greatest.

Immediate weight bearing as tolerated (WBAT) correlates with a decreased length of stay post intramedullary fixation for subtrochanteric fractures: a multicenter retrospective cohort study.

BACKGROUND: Subtrochanteric femur fractures associate with a relatively high complication rate and are traditionally treated operatively with a period of limited weight bearing. Transitioning from extramedullary to intramedullary implants, there are increasing biomechanical and clinical data to support early weight bearing. This multicenter retrospective study examines the effect of postoperative weight bearing as tolerated (WBAT) for subtrochanteric femur fractures. We hypothesize that WBAT will result in a decreased length of stay (LOS) without increasing the incidence of re-operation. METHODS: This study assesses total LOS and postoperative LOS after intramedullary fixation for subtrochanteric fractures between postoperative weight bearing protocols across 6 level I trauma centers (n = 441). Analysis techniques consisted of multivariable linear regression and nonparametric comparative tests. Additional subanalyses were performed, targeting mechanism of injury (MOI), Winquist-Hansen fracture comminution, 20-year age strata, and injury severity score (ISS). RESULTS: Total LOS was shorter in WBAT protocol within the overall sample (7.4 vs 9.7 days; p < 0.01). Rates of re-operation were similar between the two groups (10.6% vs 10.5%; p = 0.99). Stratified analysis identified patients between ages 41-80, WH comminution 2-3, high MOI, and ISS between 6-15 and 21-25 to demonstrate a significant reduction in LOS as a response to WBAT. CONCLUSION: An immediate postoperative weight bearing as tolerated protocol in patients with subtrochanteric fractures reduced length of hospital stay with no significant difference in reoperation and complication rates. If no contraindication exists, immediate weight bearing as tolerated should be considered for patients with subtrochanteric femur fractures treated with statically locked intramedullary nails. LEVEL OF EVIDENCE: Therapeutic Level III.

Delays to Surgery and Coronal Malalignment Are Associated with Reoperation after Open Tibia Fractures in Tanzania.

BACKGROUND: Treatment of diaphyseal open tibia fractures often results in reoperation and impaired quality of life. Few studies, particularly in resource-limited settings, have described factors associated with outcomes after these fractures. QUESTIONS/PURPOSES: (1) Which patient demographic, perioperative, and treatment characteristics are associated with an increased risk of reoperation after treatment of open tibia fractures with intramedullary nailing or an external fixation device in Tanzania? (2) Which patient demographic, perioperative, and treatment characteristics are associated with worse 1-year quality of life after treatment of open tibia fractures with intramedullary nailing or an external fixation device in Tanzania? METHODS: A prospective study was completed in parallel to a similarly conducted RCT at a tertiary referral center in Tanzania that enrolled adult patients with diaphyseal open tibia fractures from December 2015 to March 2017. Patients were treated with either a statically locked intramedullary nail or external fixator and examined at 2 weeks, 6 weeks, 3 months, 6 months, and 1 year postoperatively. The primary outcome, reoperation, was any deep infection or nonunion treated with a secondary intervention. The secondary outcome was the 1-year EuroQol-5D (EQ-5D) index score. There were 394 patients screened and ultimately, 267 patients enrolled in the study (240 from the primary RCT and 27 followed for the purposes of this study). Of these, 90% (240 of 267) completed 1-year follow-up and were included in the final analysis. This group comprised 110 patients who underwent IMN and 130 who had external fixation; follow-up was similar between study groups. Patients were an average of 33 years old and were primarily males who sustained road traffic injuries resulting in AO/Orthopaedic Trauma Association (OTA) classification type A or B fractures. There were 51 reoperations. For the purposes of analysis, all patients were pooled to identify all other factors, in addition to treatment type, associated with increased risk of reoperation and 1-year quality of life. An exploratory bivariable analysis identifying various factors associated with reoperation risk and EQ-5D was subsequently included in a multivariate modeling procedure to control for confounding of effect on our primary outcome. Multivariable modeling was performed using standard hierarchical modeling simplification procedures with log-likelihood ratios. Alpha levels were set to 0.05. RESULTS: After controlling for potentially confounding variables such as gender, smoking status, mechanism of injury, and treatment type, the following factors were independently associated with reoperation: Time from hospital presentation to surgery more than 24 hours (odds ratio 7.7 [95% confidence interval 2.1 to 27.8; p = 0.002), AO/OTA fracture classification Type 42C fracture (OR 4.2 [95% CI 1.2 to 14.0]; p = 0.02), OTA-Open Fracture Classification muscle loss (OR 7.5 [95% CI 1.3 to 42.2]; p = 0.02), and varus coronal angle on an immediate postoperative AP radiograph (OR 4.8 [95% CI 1.2 to 14.0]; p = 0.002). After again controlling for confounding variables such as gender, smoking status, mechanism of injury, and treatment type factors independently associated with worse 1-year EQ-5D scores included: Wound length ≥ 10 cm (ß = [change in EQ-5D score] -0.081 [95% CI -0.139 to -0.023]; p = 0.006), OTA-Open Fracture Classification muscle loss (ß = -0.133 [95% CI -0.215 to -0.051]; p = 0.002), and OTA-Open Fracture Classification bone loss (ß = -0.111 [95% CI -0.208 to -0.013]; p = 0.03). We observed a modest, but independent association between reoperation and worse 1-year EQ-5D scores (ß = -0.113 [95% CI -0.150 to -0.077]; p < 0.001). CONCLUSIONS: We found two potentially modifiable factors associated with the risk of reoperation: reducing time to surgical treatment and avoiding varus coronal angulation during definitive stabilization. Hospitals may be able to minimize time to surgery, and thus, reoperation, by increasing the number of available operative personnel and space and emphasizing the importance of open tibia fractures as an injury requiring emergent orthopaedic management. Given the lack of fluoroscopy in the study setting and similar settings, surgeons should emphasize appropriate fracture alignment, even into slight valgus, to avoid varus angulation and subsequent reoperation risk. LEVEL OF EVIDENCE: Level II, therapeutic study.

Practice Patterns for Management of Pediatric Femur Fractures in Low- and Middle-Income Countries.

BACKGROUND: Femoral shaft fractures in children are common in low and middle income countries. In high-income countries, patient age, fracture pattern, associated injuries, child/family socioeconomic status, and surgeon preference dictate fracture management. There is limited literature on treatment patterns for pediatric femur fractures in resource-limited settings. This study surveys surgeons from low (LIC), lower-middle (LMIC), and upper-middle income (UMIC) countries regarding treatment patterns for pediatric femur fractures. METHODS: Surgeons completed an electronic survey reporting surgeon demographics and treatment preference for pediatric femur fractures. Treatment preferences and indications for treatment were separated into 4 groups: infant (0 to 6 mo); toddler (7 mo to 4 y); child (5 to 12 y); adolescent (12 to 17 y). The survey was available in English, Spanish, and French. Analysis was completed with t test and χ test for continuous and categorical variables, respectively, and weighted Pearson correlation (P<0.05). RESULTS: Survey respondents consisted of 413 surgeons from 83 countries (20 LIC, 33 LMIC, 30 UMIC). The majority of respondents were fellowship trained (83%) most commonly in pediatrics (26%) and trauma (43%). Most treated >10 pediatric femur fractures per year (68%). Respondents reported treating infant femur fractures nonoperatively using Pavlik harness (19%), spica cast (60%), or traction with delayed spica cast (14%). Decreasing socioeconomic status was associated with higher nonoperative treatment rate in toddlers, children, and adolescents. Respondents commonly utilize bed rest and traction for child femur fractures in LICs (63%) and LMICs (65%) compared with UMICs (35%) (UMIC vs. LMIC P<0.001; UMIC vs. LIC P<0.001). Surgeries in children more commonly involve open reduction with internal fixation (UMIC 19%, LMIC 33%, LIC 40%; P<0.05 between UMIC-LMIC and UMIC-LIC). CONCLUSION: This is one of the largest surveys describing treatment patterns for pediatric femur fractures in low and middle income countries. Differences are evident including lower operative treatment rate in younger children and lower intramedullary fixation rates in older children. Future studies should investigate the value of treatment options in resource-limited settings. LEVEL OF EVIDENCE: Level II-prospective comparative study.

The Cost of Intramedullary Nailing Versus Skeletal Traction for Treatment of Femoral Shaft Fractures in Malawi: A Prospective Economic Analysis.

BACKGROUND: In many low- and middle-income countries, non-surgical management of femoral shaft fractures using skeletal traction is common because intramedullary (IM) nailing is perceived to be expensive. This study assessed the cost of IM nailing and skeletal traction for treatment of femoral shaft fractures in Malawi. METHODS: We used micro-costing methods to quantify the costs associated with IM nailing and skeletal traction. Adult patients who sustained an isolated closed femur shaft fracture and managed at Queen Elizabeth Central Hospital in Malawi were followed from admission to discharge. Resource utilization and time data were collected through direct observation. Costs were quantified for procedures and ward personnel, medications, investigations, surgical implants, disposable supplies, procedures instruments and overhead. RESULTS: We followed 38 nailing and 27 traction patients admitted between April 2016 and November 2017. Nailing patient's average length of stay (LOS) was 36.35 days (SD 21.19), compared to 61 (SD 18.16) for traction (p = 0.0003). The total cost per patient was $596.97 ($168.81) for nailing and $678.02 (SD $144.25) for traction (p = 0.02). Major cost drivers were ward personnel and overhead; both are directly proportional to LOS. Converting patients from traction to nailing is cost-saving up to day 23 post-admission. CONCLUSION: Savings from IM nailing as compared with skeletal traction were achieved by shortened LOS. Although this study did not assess the effectiveness of either intervention, the literature suggests that traction carries a higher rate of complications than nailing. Investment in IM nailing capacity may yield substantial net savings to health systems, as well as improved clinical outcomes.

The extent of pediatric orthopaedic research in low- and middle-income countries and the impact of academic collaboration on research quality: a scoping review.

INTRODUCTION: This review aims to (1) assess the breadth of pediatric orthopaedic research in low- and middle-income countries (LMICs) and (2) determine the impact of academic collaboration (an LMIC and a non-LMIC investigator) in published LMIC research. METHODS: Pediatric orthopaedic clinical studies conducted in LMICs from 2004 to 2014 were extracted from Embase, Cochrane, and Pubmed databases. Of 22,714 searched studies, 129 met inclusion criteria. RESULTS: 85% generated low-quality evidence (level IV or lower). 21% were collaborative, and these were more likely than non-collaborative papers to generate level III evidence or higher (25% vs 13%, p = 0.141). DISCUSSION: Pediatric orthopaedic research produced by LMICs rarely achieves level I-III evidence, but collaborative studies are associated with higher levels of evidence. LEVEL OF EVIDENCE: N/A.

The Cost of Intramedullary Nailing for Femoral Shaft Fractures in Dar es Salaam, Tanzania.

BACKGROUND: Femoral shaft fractures are one of the most common injuries seen by surgeons in low- and middle-income countries (LMICs). Surgical repair in LMICs is often dismissed as not being cost-effective or unsafe, though little evidence exists to support this notion. Therefore, the goal of this study is to determine the cost of intramedullary nailing of femoral shaft fractures in Tanzania. METHODS: We used micro-costing methods to estimate the fixed and variable costs of intramedullary nailing of femoral shaft fractures. Variable costs assessed included medical personnel costs, ward personnel costs, implants, medications, and single-use supplies. Fixed costs included costs for surgical instruments and administrative and ancillary staff. RESULTS: 46 adult femoral shaft fracture patients admitted to Muhimbili Orthopaedic Institute between June and September 2014 were enrolled and treated with intramedullary fixation. The total cost per patient was $530.87 (SD $129.99). The mean variable cost per patient was $419.87 (SD $129.99), the largest portion coming from ward personnel $144.47 (SD $123.30), followed by implant $134.10 (SD $15.00) medical personnel $106.86 (SD $28.18), and medications/supplies $30.05 (SD $12.28). The mean fixed cost per patient was $111.00, consisting of support staff, $103.50, and surgical instruments, $7.50. CONCLUSIONS: Our study provides empirical information on the variable and fixed costs of intramedullary nailing of femoral shaft fractures in LMICs. Importantly, the lack of surgical capacity was the primary driver of the largest cost for this procedure, preoperative ward personnel time. Our results provide the cost data for a formal cost-effectiveness analysis on this intervention.

Short-term complications have more effect on cost-effectiveness of THA than implant longevity.

BACKGROUND: Outcomes research in THA has focused largely on long-term implant survivorship as a primary outcome and emphasized the development of new implant technologies. In contrast, strategies to improve short-term outcomes, such as the frequencies of periprosthetic joint infections and unplanned readmissions, have received less attention. QUESTIONS/PURPOSES: We asked whether reductions in periprosthetic joint infections and early readmissions would have greater influence on the net monetary benefit (a summation of lifetime cost and quality of life) for THA compared with equivalent reductions in aseptic loosening. METHODS: A Markov model was created using decision-analysis software with six health states and death to represent seven major potential outcomes of THA. We compared the effect of a 10% reduction in each of the following outcomes: (1) periprosthetic joint infection, (2) hospital readmission, and (3) aseptic loosening. Procedure costs (not charges) were derived from our hospital cost-accounting system. Probabilities were derived primarily from the Australian Orthopaedic Association National Joint Replacement Registry, and utilities were estimated from a previous study at our institution using the time trade-off method. The primary outcome of the study is the net monetary benefit, which combines the reductions in cost and improvement in health-related quality of life in a single metric. Quality of life is expressed in quality-adjusted life years (QALYs), which are calculated by multiplying the utility of a health state (ranging from 0 to 1) by the duration of time in the health state. The cost and QALYs are reported separately as secondary outcomes. One-way and multivariate sensitivity analyses were performed including a probabilistic sensitivity analysis to account for uncertainty in model inputs. RESULTS: The net monetary benefit for a 10% reduction in periprosthetic joint infections was USD 278 (95% CI, USD 239-295) per index procedure compared with USD 174 (95% CI, USD 150-185) and USD 113 (95% CI, USD 94-129) for reductions in aseptic loosening and early readmission, respectively. Compared with the base case, reductions in cost associated with a 10% reduction in periprosthetic joint infections, early readmissions, and aseptic loosening were USD 98, USD 93, and USD 75 per index procedure, respectively. The increase in QALYs for an equivalent reduction in periprosthetic joint infections, aseptic loosening, and early readmissions were 0.0036, 0.002, and 0.0004 QALYs, respectively. Results were most sensitive to age, baseline rate of readmission, periprosthetic joint infection, aseptic loosening, and the costs of readmission and revision THA. CONCLUSIONS: Strategies to reduce periprosthetic joint infections may have a greater effect on the cost and long-term effectiveness of THA than further enhancements in implant longevity. Reductions in the rate of readmission resulted in greater reductions in cost but not quality-of-life, and therefore had smaller effect on the net monetary benefit compared with aseptic loosening. Surgeons preferentially should engage in strategies focusing on periprosthetic joint infections to improve the value of THA care. LEVEL OF EVIDENCE: Level II, economic and decision analysis.

Estimating the economic impact of complications after open tibial fracture: A secondary analysis of the pilot Gentamicin Open Tibia trial (pGO-Tibia).

Objectives: To estimate the indirect economic impact of tibial fractures and their associated adverse events (AEs) in Tanzania. Design: A secondary analysis of the pilot Gentamicin Open (pGO)-Tibia randomized control trial estimating the indirect economic impact of suffering an AE, defined as a fracture-related infection (FRI) and/or nonunion, after an open tibial fracture in Tanzania. Setting: The pGO-Tibia trial was conducted from November 2019 to August 2021 at the Muhimbili Orthopaedic Institute in Dar es Salaam, Tanzania. Patients/Participants: One hundred adults with open tibial shaft fractures participated in this study. Intervention: Work hours were compared between AE groups. Cost data were analyzed using a weighted-average hourly wage and converted into purchasing power parity-adjusted USD. Main Outcome Measurements: Indirect economic impact was analyzed from the perspective of return to work (RTW), lost productivity, and other indirect economic and household costs. RTW was analyzed using a survival analysis. Results: Half of patients returned to work at 1-year follow-up, with those experiencing an AE having a significantly lower rate of RTW. Lost productivity was nearly double for those experiencing an AE. There was a significant difference in the mean outside health care costs between groups. The total mean indirect cost was $2385 with an AE, representing 92% of mean annual income and an increase of $1195 compared with no AE. There were significantly more patients with an AE who endorsed difficulty affording household expenses postinjury and who borrowed money to pay for their medical expenses. Conclusions: This study identified serious economic burden after tibial fractures, with significant differences in total indirect cost between those with and without an AE. Level of Evidence: II.

An Analysis of Participant Preferences Regarding Virtual Versus In-person Format of Orthopaedic Surgery Educational Materials in Low- and Middle-Income Countries.

INTRODUCTION: The University of California, San Francisco Institute for Global Orthopaedics and Traumatology Surgical Management and Reconstructive Training (SMART) course has instructed orthopaedic surgeons from low-resource countries on soft-tissue reconstruction. Before the COVID-19 pandemic, the course was conducted in-person; however, it was transitioned to a virtual format during the pandemic. The aim of this study was to determine participant preferences regarding a virtual or in-person SMART course format. METHODS: Survey data were collected via e-mail after each SMART course using RedCap or Qualtrics. Statistical analyses were conducted using Stata. RESULTS: There were 247 survey respondents from 44 countries representing all world regions, with Africa (125, 51%) the most represented. Of those who attended both an in-person and virtual course, most (82%) preferred the in-person format. In addition, all measured course outcomes were significantly better for participants attending the in-person course. The most common reason for not attending an in-person course was the cost of travel (38, 51%). DISCUSSION: This study demonstrated a preference toward in-person learning for the SMART course. In addition, those surgeons participating in the in-person course endorsed increased positive outcomes from the course. Increased emphasis should be placed on in-person surgical skills training for low-resource surgeons.

Critical elements of international academic partnerships in orthopaedic surgery: a modified Delphi approach.

Background: Despite the recent emphasis on promoting international collaborations within orthopaedic surgery, criteria for determining the strengths of such partnerships has not been established. The purpose of this study was to evaluate orthopaedic experts' perceptions of the most valuable characteristics of international academic partnerships. Methods: This study was conducted using a modified Delphi methodology. Experts were identified through the Consortium of Orthopaedic Academic Traumatologists (COACT). Responses were collected from February to September 2022. Three rounds of surveys listing possible topics on a 5-point Likert scale were used to develop consensus among a group of experts. Consensus criteria for topic inclusion in the final scale was determined as a rating of "strongly agree" or "agree" by ≥70% of the participants in the third survey. Results: The Round 1 survey was distributed to 96 invited participants within the COACT network, of which 50 experts (52.1%) completed the first survey. Consensus was reached on 54 topics organized into the following 5 categories: Research, Advocacy/Leadership, Training/Surgical Skills, Education/Knowledge Exchange, and Sustainability and Safety (RATES Criteria). Conclusions: Determining the most valuable characteristics of successful international academic partnerships can lead to more sustainable, mutually beneficial collaborations. The criteria identified in this study can provide the foundation for developing new partnerships and assessing existing ones.

Establishing Consensus on Essential Resources for Musculoskeletal Trauma Care Worldwide: A Modified Delphi Study.

BACKGROUND: Despite evidence that formalized trauma systems enhance patient functional outcomes and decrease mortality rates, there remains a lack of such systems globally. Critical to trauma systems are the equipment, materials, and supplies needed to support care, which vary in availability regionally. The purpose of the present study was to identify essential resources for musculoskeletal trauma care across diverse resource settings worldwide. METHODS: The modified Delphi method was utilized, with 3 rounds of electronic surveys. Respondents consisted of 1 surgeon with expertise in musculoskeletal trauma per country. Participants were identified with use of the AO Trauma, AO Alliance, Orthopaedic Trauma Association, and European Society for Trauma and Emergency Surgery networks. Respondents rated resources on a Likert scale from 1 (most important) to 9 (least important). The "most essential" resources were classified as those rated ≤2 by ≥75% of the sampled group. RESULTS: One hundred and three of 111 invited surgeons completed the first survey and were included throughout the subsequent rounds (representing a 93% response rate). Most participants were fellowship-trained (78%) trauma and orthopaedic surgeons (90%) practicing in an academic setting (62%), and 46% had >20 years of experience. Respondents represented low-income and lower-middle-income countries (LMICs; 35%), upper-middle income countries (UMICs; 30%), and high-income countries (HICs; 35%). The initial survey identified 308 unique resources for pre-hospital, in-hospital, and post-hospital phases of care, of which 71 resources achieved consensus as the most essential. There was a significant difference (p < 0.0167) in ratings between income groups for 16 resources, all of which were related to general trauma care rather than musculoskeletal injury management. CONCLUSIONS: There was agreement on a core list of essential musculoskeletal trauma care resources by respondents from LMICs, UMICs, and HICs. All significant differences in resource ratings were related to general trauma management. This study represents a first step toward establishing international consensus and underscores the need to prioritize resources that are locally available. The information can be used to develop effective guidelines and policies, create best-practice treatment standards, and advocate for necessary resources worldwide. CLINICAL RELEVANCE: This study utilized the Delphi method representing expert opinion; however, this work did not examine patient management and therefore does not have a clinical Level of Evidence.

Delays in Debridement of Open Femoral and Tibial Fractures Increase Risk of Infection.

BACKGROUND: Infection remains a costly, devastating complication following the treatment of open fractures. The appropriate timing of debridement is controversial, and available evidence has been conflicting. METHODS: This study is a retrospective analysis of the SIGN (Surgical Implant Generation Network) Surgical Database (SSDB), a prospective registry of fracture cases in predominantly low-resource settings. Skeletally mature patients (≥16 years of age) who returned for follow-up at any time point after intramedullary nailing of an open femoral or tibial fracture were included. Patients were excluded if they had delays in debridement exceeding 7 days after the injury. Utilizing a model adjusting for potential confounders, including patient demographic characteristics, injury characteristics, country income level, and hospital type and resources, local logistic regression analysis was performed to evaluate the probability of infection with increasing time to debridement in 6-hour increments. RESULTS: In this study, 27.3% of patients met the eligibility criteria and returned for follow-up, with a total of 10,651 fractures from 61 countries included. Overall, the probability of infection increased by 0.17% for every 6-hour delay in debridement. On subgroup analysis, the probability of infection increased by 0.23% every 6 hours for Gustilo-Anderson type-III injuries compared with 0.13% for Gustilo-Anderson type-I or II injuries. The infection risk increased every 6 hours by 0.18% for tibial fractures compared with 0.13% for femoral fractures. CONCLUSIONS: There was a linear and cumulative increased risk of infection with delays in debridement for open femoral and tibial fractures. Such injuries should be debrided promptly and expeditiously. The size and international nature of this cohort make these findings uniquely generalizable to nearly all environments where such injuries are treated. LEVEL OF EVIDENCE: Therapeutic Level III . See Instructions for Authors for a complete description of levels of evidence.

Pilon fractures: Consensus and controversy.

Pilon fractures are complex injuries that require an individualized approach to treatment to avoid complications and achieve good outcomes. Staged open reduction internal fixation remains the gold standard for most cases to achieve anatomic articular reduction while minimizing soft tissue complications and infection. Careful preoperative planning based on computed tomography dictates the surgical approach for reduction. A subset of cases may be amenable to early definitive or provisional open reduction and internal fixation based on fracture pattern. In some cases of severe articular comminution where reconstruction is not possible, primary ankle arthrodesis may be a good alternative.

Transfemoral amputation and prosthesis provision in Tanzania: Patient and provider perspectives.

Background: The burden of disability because of traumatic limb amputation, particularly transfemoral amputation (TFA) is disproportionately carried by low- and middle-income countries. The need for improved access to prosthesis services in these settings is well-documented, but perspectives on the burden imposed by TFA and the challenges associated with subsequent prosthesis provision vary among patients, caregivers and healthcare providers. Objectives: To examine the burden of TFA and barriers to prosthesis provision as perceived by patient, caregiver and healthcare professional, at a single tertiary referral hospital in Tanzania. Method: Data were collected from five patients with TFA and four caregivers recruited via convenience sampling, in addition to 11 purposively sampled healthcare providers. All participants participated in in-depth interviews regarding their perceptions of amputation, prostheses and underlying barriers to improving care for persons with TFA in Tanzania. A coding schema and thematic framework were established from interviews using inductive thematic analysis. Results: All participants noted financial and psychosocial burdens of amputation, and perceived prostheses as an opportunity for return to normality and independence. Patients worried about prosthesis longevity. Healthcare providers noted significant obstacles to prosthesis provision, including infrastructural and environmental barriers, limited access to prosthetic services, mismatched patient expectations and inadequate coordination of care. Conclusion: This qualitative analysis identifies factors influencing prosthesis-related care for patients with TFA in Tanzania which are lacking in the literature. Persons with TFA and their caregivers experience numerous hardships exacerbated by limited financial, social and institutional support. Contribution: This qualitative analysis informs future directions for research into improving prosthesis-related care for patients with TFA in Tanzania.

Orthopaedic trauma observerships in North America for international surgeons: the visitors' perspective.

International observerships are one of many efforts aimed at addressing disparities in orthopaedic trauma care globally. However, their impact on visiting surgeons and their home countries, as well as the challenges faced by participating surgeons, are not well-documented. Methods: A survey was distributed to overseas surgeons who participated in an orthopaedic trauma observership from 2009 to 2020. Surgeons were identified through North American institutions previously recognized by the authors as having hosted international observerships. Information gathered included participant demographics, details of and perceived impact of the observership, and barriers faced before, during, and after the program. Responses from 148 international surgeons (ISs) from 49 countries were analyzed. Results: Sixty percent of observerships were at academic programs, 57% lasted 1-3 months, and 60% were self-funded. Participants identified cost and housing as primary barriers. After completing their observership, lack of funding, equipment and support staff, and excessive workload prevented participants from implementing changes at their clinical practice. Most observers believed that they gained relevant clinical (89%) and surgical knowledge (67%) and developed a professional network of North American hosts (63%). The most common suggested changes to the observership were greater hands-on experience in the operating room and structured goal setting relevant to the visiting surgeon. Conclusions: Visiting surgeons find North American orthopaedic trauma observerships helpful in improving their surgical and clinical skills. However, financial constraints and resource limitations at their clinical practice and limited operative experience during the observership present barriers to maximizing this clinical experience. To enhance the relevance of clinical observerships for ISs and impact global orthopaedic trauma care, the unique needs and challenges facing ISs must be addressed. Level of Evidence: IV-Cross-Sectional Study.

Opportunities for International Orthopaedic Volunteerism: An Exploration of United States and Canada-Based Nonprofit Organizations.

BACKGROUND: In low and middle-income countries (LMICs), there are often not enough orthopaedic surgeons to treat musculoskeletal conditions. International volunteerism is 1 way that the orthopaedic community seeks to meet this need. This study explored the opportunities available for orthopaedic surgeons to volunteer overseas as offered by nonprofit organizations in the United States and Canada. METHODS: A systematic internet search was conducted using 2 distinct search strategies. A website was considered a "hit" if it was that of a U.S. or Canada-based nonprofit, volunteer, or non-governmental organization that had opportunities for international orthopaedic volunteerism. Duplicate hits were eliminated to identify distinct organizations. Data regarding the work and geographical reach of the organization, as well as changes to its volunteer programs as a result of COVID-19, were extracted from each hit. RESULTS: Of the 38 distinct organizations identified in the U.S. and Canada, the most common orthopaedic subspecialties represented were pediatrics (37%), hand (24%), and arthroplasty (18%). Foot and ankle (4 organizations; 11%), sports medicine (2 organizations; 5%), and oncology (1 organization; 3%) were the least represented subspecialities. The most common regions for volunteer trips included Latin America and the Caribbean, followed by West and East Africa. Twelve organizations (32%) were identified as having a religious affiliation. For most organizations, the trip duration was a minimum of 1 week. All volunteer organizations included operative or clinical experiences as part of their trips, and the majority of organizations (58%) reported that their trips included opportunities for training local surgeons. Many organizations (71%) reported having resumed trips after halting them during the COVID-19 pandemic. CONCLUSIONS: Many opportunities exist for orthopaedic surgeons to volunteer their time and skills abroad. Future directions for the improvement of international volunteer efforts among the orthopaedic community could include expanding the number of existing volunteer opportunities and assessing the ethics, safety, efficacy, and longevity of these programs.

Novel e-learning platform for orthopaedic training in LMICs: A descriptive review of the IGOT portal.

Background: While e-learning has been written about extensively within the context of orthopaedics in the United States, there are few articles describing e-learning initiatives geared towards low-and middle-income countries (LMICs). The Institute for Global Orthopaedics and Traumatology (IGOT) at the University of California, San Francisco (UCSF) developed the IGOT Learning Portal to meet this need. Methods: The IGOT Learning Portal was designed to address knowledge gaps in patient care by increasing access to high-quality orthopaedic education for surgeons and trainees worldwide. It offers 10 distinct, asynchronous courses, which are divided into a modular format. Course enrollment is free and accessible to any surgeon or trainee with a web-browsing capable device and internet connection. Results: There are more than 2700 registered users and 300 active learners enrolled in IGOT Learning Portal courses. The Surgical Management and Reconstructive Training (SMART) program is the most commonly taken course. Learners represent 32 different countries across six continents. The IGOT portal also has surgical videos available on YouTube. The IGOT Portal YouTube channel has over 2000 subscribers and over 143,000 total views. Conclusions: The IGOT Learning Portal is an innovative approach to address the global disparity in orthopaedic trauma care by improving access to high-quality surgical education for surgeons and trainees both in the US and internationally. The development of an interactive online forum may be a beneficial addition to the Portal. Future directions include assessing content retention, participant interaction, and expanding existing content to other orthopaedic subspecialties.

GO-Tibia: a masked, randomized control trial evaluating gentamicin versus saline in open tibia fractures.

BACKGROUND: The rate of open tibia fractures is rapidly increasing across the globe due to a recent rise in road traffic accidents, predominantly in low- and low-middle-income countries. These injuries are orthopedic emergencies associated with infection rates as high as 40% despite the use of systemic antibiotics and surgical debridement. The use of local antibiotics has shown some promise in reducing the burden of infection in these injuries due to increasing local tissue availability; however, no trial has yet been appropriately powered to evaluate for definitive evidence and the majority of current studies have taken place in a high-resource countries where resources and the bio-burden may be different. METHODS: This is a prospective randomized, masked, placebo-controlled superiority trial designed to evaluate the efficacy of locally administered gentamicin versus placebo in the prevention of fracture-related infection in adults (age > 18 years) with primarily closeable Gustillo-Anderson class I, II, and IIIA open tibia fractures. Eight hundred ninety patients will be randomized to receive an injection of either gentamicin (treatment group) or saline (control group) at the site of their primarily closed open fracture. The primary outcome will be the occurrence of a fracture-related infection occurring during the course of the 12-month follow-up. DISCUSSION: This study will definitively assess the effectiveness of local gentamicin for the prevention of fracture-related infections in adults with open tibia fractures in Tanzania. The results of this study have the potential to demonstrate a low-cost, widely available intervention for the reduction of infection in open tibia fractures. TRIAL REGISTRATION: Clinicaltrials.gov NCT05157126. Registered on December 14, 2021.

A pilot, masked, randomized controlled trial to evaluate local gentamicin versus saline in open tibial fractures (pGO-Tibia).

Background: Open tibial fractures have a high risk of infection that can lead to severe morbidity. Antibiotics administered locally at the site of the open wound are a potentially effective preventive measure, but there are limited data evaluating aminoglycoside antibiotics. The objective of this study was to assess the feasibility of a clinical trial to test the efficacy of local gentamicin in reducing the risk of fracture-related infection after open tibial fracture. Methods: This study is a single-center, pilot, masked, randomized controlled trial conducted at the Muhimbili Orthopaedic Institute. Participants were randomized intraoperatively after wound closure to receive gentamicin solution or normal saline solution injected at the fracture site. Follow-ups were completed at 2 weeks, 6 weeks, 3 months, 6 months, 9 months, and 1 year postoperatively. The primary feasibility outcomes were the rate of enrollment and retention. The primary clinical outcome was the occurrence of fracture-related infection. Results: Of 199 patients screened, 100 eligible patients were successfully enrolled and randomized over 9 months (11.1 patients/month). Complete data were recorded at baseline and follow-up for >95% of cases. The rate of follow-up at 6 weeks, 3 months, 6 months, 9 months, and 1 year were 70%, 68%, 69%, 61%, and 80%, respectively. There was no difference in adverse events or any of the measured primary and secondary outcomes. Conclusion: This pilot study is among the first to evaluate locally administered gentamicin in open tibial fractures. Results indicate a rigorous clinical trial with acceptable rates of enrollment and follow-up to address this topic is possible in this setting.
