RESUMO
The modern management of open fractures was established after the foundational work of Gustilo and Anderson, but we continue to strive to determine the optimal treatment of open fractures to diminish the risk of infection. The ideal timing of antibiotics, presentation to the operating room, and timing of procedures such as flap coverage continue to be investigated with incremental changes recommended over the years. This article aims to provide the most recent review of the literature regarding the timing and management of both upper and lower extremity open fractures, pediatric open fractures, current topics of controversy, and the data supporting current treatment recommendations.

INTRODUCTION: The incidence of infection in open tibial shaft injuries varies with the severity of the injury with rates ranging from roughly 2% for Gustilo-Anderson type I to nearly 43% for type IIIB fractures. As with all fractures, timely antibiotics administration in the emergency department (ED) is an essential component of fracture management and infection prevention. This study identifies factors associated with the expedient administration of antibiotics for open tibial shaft fractures. METHODS: This retrospective study identified patients treated for open tibial shaft fractures at an academic level 1 trauma center between 2015 and 2021. Open fractures were identified by reviewing patient charts. We used chart reviews to gather demographics, fracture characteristics, postoperative outcomes, trauma activation, and time to antibiotic order, delivery, and operating room. Univariate analysis was used to compare patients who received antibiotics within 1 h of ED presentation to those who did not. Multivariate analysis was performed to investigate factors associated with faster delivery of antibiotics. RESULTS: Among 70 ED patients with open tibial shaft fractures, 39 (56%) received early administration of antibiotics. Arrival at the ED via emergency medical service (EMS) as opposed to walking in (98% vs. 74%, p = 0.01) and trauma activation (90% vs. 52%, p < 0.001) were significantly more common in the early administration group than the late group. The early group had shorter intervals between antibiotic order and delivery (0.02 h vs. 0.35 h, p = 0.007). Multivariate analysis suggested that trauma activation, EMS arrival, and arrival during non-overnight shifts were independent predictors of a shorter time to antibiotic administration (odds ratios 11.9, 30.7, and 5.4, p = 0.001, 0.016, and 0.013, respectively). DISCUSSION: Earlier antibiotic delivery is associated with non-overnight arrival at the ED, arrival via EMS, and a coordinated trauma activation. Our findings indicate that in cases where administering antibiotics is critical to achieving positive outcomes, it is advisable to initiate a coordinated trauma response. Furthermore, hospital personnel should be attentive to the need for rapid administration of antibiotics to patients with open fractures who arrive via walk-in or during late-night hours.

PURPOSE: The rise of artificial intelligence (AI) models like ChatGPT offers potential for varied applications, including patient education in healthcare. With gaps in osteoporosis and bone health knowledge and adherence to prevention and treatment, this study aims to evaluate the accuracy of ChatGPT in delivering evidence-based information related to osteoporosis. METHODS: Twenty of the most common frequently asked questions (FAQs) related to osteoporosis were subcategorized into diagnosis, diagnostic method, risk factors, and treatment and prevention. These FAQs were sourced online and inputted into ChatGPT-3.5. Three orthopedic surgeons and one advanced practice provider who routinely treat patients with fragility fractures independently reviewed the ChatGPT-generated answers, grading them on a scale from 0 (harmful) to 4 (excellent). Mean response accuracy scores were calculated. To compare the variance of the means across the four categories, a one-way analysis of variance (ANOVA) was used. RESULTS: ChatGPT displayed an overall mean accuracy score of 91%. Its responses were graded as "accurate requiring minimal clarification" or "excellent," with a mean response score ranging from 3.25 to 4. No answers were deemed inaccurate or harmful. No significant difference was observed in the means of responses across the defined categories. CONCLUSION: ChatGPT-3.5 provided high-quality educational content. It showcased a high degree of accuracy in addressing osteoporosis-related questions, aligning closely with expert opinions and current literature, with structured and inclusive answers. However, while AI models can enhance patient information accessibility, they should be used as an adjunct rather than a substitute for human expertise and clinical judgment.

INTRODUCTION: Web-based resources serve as a fundamental educational platform for orthopaedic trauma patients; however, they are frequently written above the recommended sixth-grade reading level, and previous studies have demonstrated this for the American Academy of Orthopaedic Surgeons (AAOS) web-based articles. In this study, we perform an updated assessment of the readability of AAOS trauma-related educational articles as compared with injury-matched education materials developed by the Orthopaedic Trauma Association (OTA). METHODS: All 46 AAOS trauma-related web-based ( https://www.orthoinfo.org/ ) patient education articles were analyzed for readability. Two independent reviewers used (1) the Flesch-Kincaid Grade Level (FKGL) and (2) the Flesch Reading Ease (FRE) algorithms to calculate the readability level. Mean readability scores were compared across body part categories. A one-sample t -test was done to compare mean FKGL with the recommended sixth-grade readability level and the average American adult reading level. A two-sample t -test was used to compare the readability scores of the AAOS trauma-related articles with those of the OTA. RESULTS: The average (SD) FKGL and FRE for the AAOS articles were 8.9 (0.74) and 57.2 (5.8), respectively. All articles were written above the sixth-grade reading level. The average readability of the AAOS articles was significantly greater than the recommended sixth-grade reading level ( P < 0.001). The average FKGL and FRE for all AAOS articles were significantly higher compared with those of the OTA articles (8.9 ± 0.74 versus 8.1 ± 1.14, P < 0.001 and 57.2 ± 5.8 versus 65.6 ± 6.6, P < 0.001, respectively). Excellent agreement was observed between raters for the FKGL 0.956 (95% confidence interval, 0.922 to 0.975) and FRE 0.993 (95% confidence interval, 0.987 to 0.996). DISCUSSION: Our findings suggest that after almost a decade, the readability of the AAOS trauma-related articles remains unchanged. The AAOS and OTA trauma patient education materials have high readability levels and may be too difficult for patient comprehension. A need remains to improve the readability of these commonly used trauma education materials.

Introduction: The purpose of this study was to describe the outcomes after operative repair of ballistic femoral neck fractures. To better highlight the devastating nature of these injuries, we compared a cohort of ballistic femoral neck fractures to a cohort of young, closed, blunt-injury femoral neck fractures treated with open reduction and internal fixation (ORIF). Methods: Retrospective chart review identified all patients presenting with ballistic femoral neck fractures treated at three academic trauma centers between January 2016 and December 2021, as well as patients aged ≤50 with closed, blunt-injury femoral neck fractures who received ORIF. The primary outcome was failure of ORIF, which includes the diagnosis of non-union, avascular necrosis, conversion to total hip arthroplasty, and conversion to Girdlestone procedure. Additional outcomes included deep infection, postoperative osteoarthritis, and ambulatory status at last follow-up. Results: Fourteen ballistic femoral neck fractures and 29 closed blunt injury fractures were identified. Of the ballistic fractures, 7 (50%) patients had a minimum of 1-year follow-up or met the failure criteria. Of the closed fractures, 16 (55%) patients had a minimum of 1-year follow-up or met the failure criteria. Median follow-up was 21 months. 58% of patients with ballistic fractures were active tobacco users. Five of 7 (71%) ballistic fractures failed, all of which involved non-union, whereas 8 of 16 (50%) closed fractures failed (p=0.340). No outcomes were significantly different between cohorts. Conclusion: Our results demonstrate that ballistic femoral neck fractures are associated with high rates of non-union. Large-scale multicenter studies are necessary to better determine optimal treatment techniques for these fractures. Level of evidence: Level III. Retrospective cohort study.
RESUMO
PURPOSE: Gluteal compartment syndrome (GCS) is a rare but devastating condition with a paucity of literature to help guide diagnosis and management. This study aims to identify and describe the risk factors and patient characteristics associated with GCS to facilitate early diagnosis. METHODS: This is a retrospective case series of patients undergoing gluteal compartment release between 2015 and 2022 at an academic Level I trauma center. Chart reviews were performed to extract data on patient demographics, presenting symptoms, risk factors, operative findings, and postoperative outcomes. RESULTS: 14 cases of GCS were identified. 12 (85.7%) were male, with a mean age of 39.4 ± 13 years and a mean BMI of 25.1 ± 4.1 kg/m2. 12 (85.7%) patients did not present as traumas and only 3 had ≥ 1 fracture. 9 patients reported drug use. Hemoglobin (Hgb) (11.7 ± 4 g/dL) was generally low (5 had Hgb < 10 g/dL). Creatine kinase (49,617 ± 60,068 units/L) was consistently elevated in all cases, and lactate (2.8 ± 1.6 mmol/L) was elevated in 9. 13 had non-viable muscle requiring debridement. Postoperatively, the mean ICU length of stay was 12 ± 23 days. 2 patients died during admission and all remaining patients required discharge to rehabilitation facilities. CONCLUSION: GCS is more likely to present in a young to middle-aged, otherwise healthy, male using drugs who is either found down or experienced an iatrogenic injury. Recognizing that GCS is different from that of the leg, in terms of etiology, may help avoid delays in diagnosis and treatment.

We report the case of a 53-year-old male who developed polycompartment syndrome (PCS) secondary to cardiogenic shock. After suffering a cardiac arrest, a self-perpetuating cycle of intra-abdominal hypertension (IAH) and vital organ damage led to abdominal compartment syndrome (AbCS), which then contributed to the precipitation of extremity compartment syndrome (CS) in bilateral thighs, legs, forearms, and hands. This report is followed by a review of the literature regarding the pathophysiology of this rare sequela of cardiogenic shock. While the progression from cardiogenic shock to AbCS and ultimately to PCS has been hypothesized, no prior case reports demonstrate this. Furthermore, this case suggests more generally that IAH may be a risk factor for extremity CS. Future studies should examine the potential interplay between IAH and extremity CS in patients at risk, such as polytrauma patients with tibial fractures.
RESUMO
OBJECTIVES: The primary purpose of this study was to identify factors associated with the development of arterial line-related limb ischemia in patients on extracorporeal membrane oxygenation (ECMO). The authors also sought to characterize and report the outcomes of patients who developed arterial line-related limb ischemia. DESIGN: Retrospective cohort study. SETTING: A single academic tertiary referral ECMO center. PARTICIPANTS: Consecutive patients who were treated with ECMO over 6 years. INTERVENTIONS: Use of arterial line. MEASUREMENTS AND MAIN RESULTS: A total of 278 consecutive ECMO patients were included, with 19 (7%) patients developing arterial line-related limb ischemia during the ECMO run. Postcannulation Sequential Organ Failure Assessment (SOFA) (adjusted odds ratio [aOR] 1.20, 95% CI 1.08-1.32), Acute Physiology and Chronic Health Evaluation-II (aOR 0.84, 95% CI 0.74-0.95), and adjusted Vasopressor Dose Equivalence (aOR 1.03, 95% CI 1.01-1.05) scores were independently associated with the development of arterial line-associated limb ischemia. A SOFA score of ≥17 at the time of ECMO cannulation had an 80% sensitivity and 87% specificity for predicting arterial line-related limb ischemia. CONCLUSIONS: Arterial line-related limb ischemia is much more common in ECMO patients than in the typical intensive care unit setting. The SOFA score may be useful in identifying which patients may be at risk for arterial line-related limb ischemia. As this was a single-center retrospective study, these results are inherently exploratory, and prospective multicenter studies are necessary to validate these results.

Our primary objective was to identify if fasciotomy was associated with increased mortality in patients who developed acute compartment syndrome (ACS) on extracorporeal cardiopulmonary resuscitation (ECPR). Additionally, we sought to identify any additional risk factors for mortality in these patients and report the amputation-free survival following fasciotomy. We retrospectively reviewed adult ECPR patients from the Extracorporeal Life Support Organization registry who were diagnosed with ACS between 2013 and 2021. Of 764 ECPR patients with limb complications, 127 patients (17%) with ACS were identified, of which 78 (63%) had fasciotomies, and 14 (11%) had amputations. Fasciotomy was associated with a 23% rate of amputation-free survival. There were no significant differences in demographics or baseline laboratory values between those with and without fasciotomy. Overall, 88 of 127 (69%) patients with ACS died. With or without fasciotomy, the mortality of ACS patients was similar, 68% vs. 71%. Multivariable logistic regression demonstrated that body mass index (BMI; adjusted odds ratio [aOR] = 1.22, 95% confidence interval [CI] = 1.01-1.48) and 24 hour mean blood pressure (BP; aOR = 0.93, 95% CI = 0.88-0.99) were independently associated with mortality. Fasciotomy was not an independent risk factor for mortality (aOR = 0.24, 95% CI = 0.03-1.88). The results of this study may help guide surgical decision-making for patients who develop ACS after ECPR. However, the retrospective nature of this study does not preclude selection bias in patients who have received fasciotomy. Thus, prospective studies are necessary to confirm these findings.

OBJECTIVE: To correlate patient-specific and surgeon-specific factors with outcomes after operative management of distal intra-articular tibia fractures. DESIGN: Retrospective cohort study. SETTING: 3 Level 1 tertiary academic trauma centers. PATIENTS/PARTICIPANTS: The study included a consecutive series of 175 patients with OTA/AO 43-C pilon fractures. MAIN OUTCOME MEASUREMENTS: Primary outcomes included superficial and deep infection. Secondary outcomes included nonunion, loss of articular reduction, and implant removal. RESULTS: The following patient-specific factors correlated with poor surgical outcomes: increased age with superficial infection rate ( P < 0.05), smoking with rate of nonunion ( P < 0.05), and Charlson Comorbidity Index with loss of articular reduction ( P < 0.05). Each additional 10 minutes of operative time over 120 minutes was associated with increased odds of requiring I&D and any treatment for infection. The same linear effect was seen with the addition of each fibular plate. The number of approaches, type of approach, use of bone graft, and staging were not associated with infection outcomes. Each additional 10 minutes of operative time over 120 minutes was associated with an increased rate of implant removal, as did fibular plating. CONCLUSIONS: While many of the patient-specific factors that negatively affect surgical outcomes for pilon fractures may not be modifiable, surgeon-specific factors need to be carefully examined because these may be addressed. Pilon fracture fixation has evolved to increasingly use fragment-specific approaches applied with a staged approach. Although the number and type of approaches did not affect outcomes, longer operative time was associated with increased odds of infection, while additional fibular plate fixation was associated with higher odds of both infection and implant removal. Potential benefits of additional fixation should be weighed against operative time and associated risk of complications. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

INTRODUCTION: It is our hypothesis that physician-specific variables affect the management of distal radius (DR) fractures in addition to patient-specific factors. METHODS: A prospective cohort study was conducted evaluating treatment differences between Certificate of Additional Qualification hand surgeons (CAQh) and board-certified orthopaedic surgeons who treat patients at level 1 or level 2 trauma centers (non-CAQh). After institutional review board approval, 30 DR fractures were selected and classified (15 AO/OTA type A and B and 15 AO/OTA type C) to create a standardized patient data set. The patient-specific demographics and surgeon's information regarding the volume of DR fractures treated per year, practice setting, and years posttraining were obtained. Statistical analysis was done using chi-square analysis with a postanalysis regression model. RESULTS: A notable difference was observed between CAQh and non-CAQh surgeons. Surgeons in practice longer than 10 years or who treat >100 DR fractures/year were more likely to choose surgical intervention and obtain a preoperative CT scan. The two most influential factors in decision making were the patients' age and medical comorbidities, with physician-specific factors being the third most influential in medical decision making. DISCUSSION: Physician-specific variables have a notable effect on decision making and are critical for the development of consistent treatment algorithms for DR fractures.

INTRODUCTION: Online educational materials have become a fundamental resource for orthopaedic surgery patients; however, they are frequently written at a high level of reading ability and are too complicated for some patients to understand. The aim of this study was to appraise the readability of the Orthopaedic Trauma Association (OTA) patient education materials. METHODS: All 41 articles on the OTA patient education website ( https://ota.org/for-patients) were analyzed for readability. Readability scores were calculated by 2 independent reviewers using the (1) FleschKincaid Grade Level (FKGL) and the (2) Flesch Reading Ease algorithms. Mean readability scores were compared across anatomic categories. One-sample t test was performed to compare mean FKGL with the recommended sixth-grade readability level and the average American adult reading level. RESULTS: The average (SD) FKGL of the 41 OTA articles was 8.15 (1.14). The average (SD) Flesch Reading Ease for the OTA patient education materials was 65.5 (6.60). Four (11%) of the articles were at or below a sixth-grade reading level. The average readability of the OTA articles was significantly higher than the recommended sixth-grade level ( P < 0.001; 95% confidence interval, 7.79-8.51). The average readability of the OTA articles was not significantly different from the average eighth-grade reading skill level of US adults ( P = 0.41; 95% confidence interval, 7.79-8.51). CONCLUSION: Our findings suggest that despite most OTA patient education materials having readability levels suitable for the average US adult, these reading materials are still above the recommended sixth-grade level and may be too difficult for patient comprehension.

BACKGROUND: Delayed wound closure is often used after open reduction and internal fixation (ORIF) of both-bone forearm fractures to reduce the risk of skin necrosis and subsequent infection caused by excessive swelling. However, no studies we are aware of have evaluated factors associated with the use of delayed wound closure after ORIF. QUESTIONS/PURPOSES: (1) What proportion of patients undergo delayed wound closure after ORIF of adult both-bone forearm fractures? (2) What factors are associated with delayed wound closure? METHODS: The medical records of all patients who underwent ORIF with plate fixation for both-bone fractures by the adult orthopaedic trauma service at our institution were considered potentially eligible for analysis. Between January 2010 and April 2022, we treated 74 patients with ORIF for both-bone forearm fractures. Patients were excluded if they had fractures that were fixed more than 2 weeks from injury (six patients), if their fracture was treated with an intramedullary nail (one patient), or if the patient experienced compartment syndrome preoperatively (one patient). No patients with Gustilo-Anderson Type IIIB and C open fractures were included. Based on these criteria, 89% (66 of 74) of the patients were eligible. No further patients were excluded for loss of follow-up because the primary endpoint was the use of delayed wound closure, which was performed at the time of ORIF. However, one further patient was excluded for having bilateral forearm fractures to ensure that each patient had a single fracture for statistical analysis. Thus, 88% (65 of 74) of patients were included in the analysis. These patients were captured by an electronic medical record search of CPT code 25575. The mean ± SD age was 34 ± 15 years and mean BMI was 28 ± 7 kg/m 2 . The mean follow-up duration was 4 ± 5 months. The primary endpoint was the use of delayed wound closure, which was determined at the time of definitive fixation if tension-free closure could not be achieved. All surgeons used a volar Henry or modified Henry approach and a dorsal subcutaneous approach to the ulna for ORIF. Univariate logistic regression was used to identify which factors might be associated with delayed wound closure. A multivariable logistic regression analysis was then performed for male gender, open fractures, age, and BMI. RESULTS: Twenty percent (13 of 65) of patients underwent delayed wound closure, 18% (12 of 65) of which occurred in patients who had high-energy injuries and 14% (nine of 65) in patients who had open fractures. Being a man (adjusted odds ratio 9.9 [95% confidence interval 1 to 87]; p = 0.04) was independently associated with delayed wound closure, after adjusting for open fractures, age, and BMI. CONCLUSION: One of five patients had delayed wound closure after ORIF of both-bone forearm fractures. Being a man was independently associated with greater odds of delayed wound closure. Surgeons should counsel all patients with these fractures about the possibility of delayed wound closure, with particular attention to men with high-energy and open fractures. Future larger-scale studies are necessary to confirm which factors are associated with the use of delayed wound closure in ORIF of both-bone fractures and its effects on fracture healing. LEVEL OF EVIDENCE: Level III, therapeutic study.

BACKGROUND: There is significant variability both in how proximal humerus fractures (PHFs) are treated and the ensuing patient outcomes. The purpose of this study was to investigate which surgeon- and patient-specific factors contribute to decision-making in the treatment of adult PHFs. We hypothesized that orthopedic sub-specialty training creates inherent bias and plays an important role in management algorithms for PHFs. METHODS: We performed a prospective cohort investigation in 2 groups of surgeons-traumatologists (N = 25) and shoulder & elbow/sports surgeons (SES) (N = 26)-and asked them to provide treatment recommendations for 30 distinct clinical cases with standardized radiographic and clinical data. This is a population-based sample of surgeons who take trauma call and treat PHFs with different sub-specializations and practice settings including academic, hospital-employed, and private. Surgeons characterized based on subspecialty (trauma vs. SES), experience level (>10 vs. ≤10-years), and employment type (hospital- vs. non-hospital-employed). Chi-square analyses, logistic mixed-effects modeling, and relative importance analysis were used to evaluate the data. RESULTS: Of the patient-specific factors, we found that the management of PHFs is largely dependent on initial radiographs obtained. Traumatologists were more likely to offer open reduction internal fixation (ORIF) and less likely to offer arthroplasty: 69% ORIF (traumatologists) vs. 51% ORIF (SES, P < .001), 8% arthroplasty (traumatologists) vs. 17% (SES, P < .001). Traumatologists were less likely to change from operative (either ORIF or arthroplasty) to non-operative management compared to SES surgeons when presented with additional patient demographic data. Surgeon-specific factors contributed to more than one-half of the variability in decision-making of PHF management while patient-specific factors contributed to about one-third of the variability in decision-making. CONCLUSIONS: As physicians strive to advance the treatment for PHFs and optimize patient outcomes, our findings highlight the complex overlap between surgeon-, fracture-, and patient-specific factors in the final decision-making process.

BACKGROUND: Little evidence is available to guide physical therapy (PT) following lower extremity fracture repair distal to the hip. As such, variability has been reported in the way PT is utilized post-operatively. Examination of current practice by orthopedic surgeons (OS) and physical therapists is needed to inform clinical practice guidelines in this area. OBJECTIVE: To describe current PT referral practices among OS, identify patient and clinical factors that affect PT referral, and examine differences between OS and physical therapists with regard to visit frequency, duration, and use of specific PT interventions. METHODS: Provider surveys. RESULTS: Surveys were completed by 100 OS and 347 physical therapists. Over half (54%) of OS reported referring "most patients" to PT and identified joint stiffness and strength limitations as top reasons for PT referral. Over 80% of OS and physical therapists indicated that joint stiffness, strength limitations, and patients' functional goals affected their recommendations for PT visit frequency. More physical therapists than OS reported that pain severity (55% vs 25%, p < .001), maladaptive pain behaviors (64% vs. 33%, p < .001), and patient self-efficacy (70% vs. 49%, p = .003) affected their visit frequency recommendations. While OS recommended more frequent PT for patients with peri-articular fractures, fracture type had minimal impact on the visit frequencies recommended by physical therapists. CONCLUSION: OS and physical therapists consider similar physical impairments when determining the need for PT and visit frequencies, however, physical therapists consider pain and psychosocial factors more often, with OS focusing more on injury type.

Introduction: Publicly available AI language models such as ChatGPT have demonstrated utility in text generation and even problem-solving when provided with clear instructions. Amidst this transformative shift, the aim of this study is to assess ChatGPT's performance on the orthopaedic surgery in-training examination (OITE). Methods: All 213 OITE 2021 web-based questions were retrieved from the AAOS-ResStudy website (https://www.aaos.org/education/examinations/ResStudy). Two independent reviewers copied and pasted the questions and response options into ChatGPT Plus (version 4.0) and recorded the generated answers. All media-containing questions were flagged and carefully examined. Twelve OITE media-containing questions that relied purely on images (clinical pictures, radiographs, MRIs, CT scans) and could not be rationalized from the clinical presentation were excluded. Cohen's Kappa coefficient was used to examine the agreement of ChatGPT-generated responses between reviewers. Descriptive statistics were used to summarize the performance (% correct) of ChatGPT Plus. The 2021 norm table was used to compare ChatGPT Plus' performance on the OITE to national orthopaedic surgery residents in that same year. Results: A total of 201 questions were evaluated by ChatGPT Plus. Excellent agreement was observed between raters for the 201 ChatGPT-generated responses, with a Cohen's Kappa coefficient of 0.947. 45.8% (92/201) were media-containing questions. ChatGPT had an average overall score of 61.2% (123/201). Its score was 64.2% (70/109) on non-media questions. When compared to the performance of all national orthopaedic surgery residents in 2021, ChatGPT Plus performed at the level of an average PGY3. Discussion: ChatGPT Plus is able to pass the OITE with an overall score of 61.2%, ranking at the level of a third-year orthopaedic surgery resident. It provided logical reasoning and justifications that may help residents improve their understanding of OITE cases and general orthopaedic principles. Further studies are still needed to examine their efficacy and impact on long-term learning and OITE/ABOS performance.
RESUMO
Outcomes of the Surgical Implant Generation Network (SIGN) nail have been reported for femur and tibial fractures, but its use in tibiotalocalcaneal arthrodesis (TTCA) is not well studied. Radiographic and clinical outcomes of TTCA using the SIGN database in patients with > 6 months of radiographic follow up were analyzed. Rates of tibiotalar (TT) fusion and subtalar (ST) fusion at final follow up were assessed by two independent reviewers. Of the 62 patients identified, use of the SIGN nail for TCCA resulted in 53% rate of fusion in the TT joint and 20% in the ST joint. Thirty-seven patients (60%) demonstrated painless weight bearing at final follow up. There were no differences in incidence of painless weight bearing between consensus fused and not fused cohorts for TT and ST joints (p > 0.05). There were five implant failures, no cases of infection, and seven cases of reoperation. (Journal of Surgical Orthopaedic Advances 32(3):187-192, 2023).

PURPOSE: Manual surgical manipulation of the tibia and fibula is necessary to properly align and reduce the space in ankle fractures involving sprain of the distal tibiofibular syndesmosis. However, manual reduction is highly variable and can result in malreduction in about half of the cases. Therefore, we are developing an image-guided robotic assistant to improve reduction accuracy. The purpose of this study is to quantify the forces associated with reduction of the ankle syndesmosis to define the requirements for our robot design. METHODS: Using a cadaveric specimen, we designed a fixture jig to fix the tibia securely on the operating table. We also designed a custom fibula grasping plate to which a force-torque measuring device is attached. The surgeon manually reduced the fibula utilizing this construct while translational and rotational forces along with displacement were being measured. This was first performed on an intact ankle without ligament injury and after the syndesmosis ligaments were cut. RESULTS: Six manipulation techniques were performed on the three principal directions of reduction at the cadaveric ankle. The results demonstrated the maximum force applied to the lateral direction to be 96.0 N with maximum displacement of 8.5 mm, applied to the anterior-posterior direction to be 71.6 N with maximum displacement of 10.7 mm, and the maximum torque applied to external-internal rotation to be 2.5 Nm with maximum rotation of 24.6°. CONCLUSIONS: The specific forces needed to perform the distal tibiofibular syndesmosis manipulation are not well understood. This study quantified these manipulation forces needed along with their displacement for accurate reduction of ankle syndesmosis. This is a necessary first step to help us define the design requirements of our robotic assistance from the aspects of forces and displacements.
