J Foot Ankle Surg 2024; 63:59-63. [PMID: 37661018 DOI: 10.1053/j.jfas.2023.08.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 08/09/2023] [Accepted: 08/26/2023] [Indexed: 09/05/2023]
Abstract
Current recommendations on thromboprophylaxis for foot and ankle (FA) surgery are often inconsistent and generally based on weak evidence. The aim of this survey study was to evaluate the current practice among orthopedic surgeons regarding venous thromboembolism (VTE) prophylaxis following FA surgery. From February 2019 to March 2020, an online questionnaire was sent by e-mail to orthopedic societies across the world. The questionnaire was hosted by the International Society of Thrombosis and Haemostais RedCAP platform. Topics of interest were VTE rates following FA surgery, duration and type of thromboprophylaxis, bleeding complications, VTE risk factors for prophylaxis and use of risk assessment. A total of 693 FA orthopedic surgeons from all continents completed the survey of whom 392 (57%) performed more than 200 FA procedures per year. A total of 669/693 (97%) respondents stated that thromboprophylaxis is necessary in FA surgeries. When thromboprophylaxis was prescribed, half of surgeons prescribed it for the duration of immobilization. Acetylsalicylic acid, low molecular weight heparin and direct-oral anticoagulants were, in this order, the preferred choice. Acetylsalicylic acid and low molecular weight heparin were predominantly prescribed in North America and Europe, respectively. Previous deep vein thrombosis, immobility, obesity and inherited thrombophilia were considered the main risk factors indicative of thromboprophylaxis use. In this survey, most surgeons agree that thromboprophylaxis is indicated for FA surgery, but the prescription, type and duration of prophylaxis differs greatly with a large intercontinental discrepancy. These survey results could be a foundation for developing uniform guidelines to optimize thromboprophylactic strategies in FA procedures around the world.

Abstract
Venous thromboembolism (VTE) is a serious medical condition that can be an unfortunate complication arising from foot and ankle surgery. Many factors may predispose a patient to a VTE event including prolonged postoperative immobilization, comorbidities, extended length of tourniquet time, and higher risk surgeries. Unfortunately, there is no clinical consensus for guidelines on VTE prophylaxis following foot and ankle surgery. In this retrospective cohort study, we present our patient population who were prophylactically anticoagulated following foot and ankle surgery along with their incidence of deep vein thrombosis and pulmonary embolism (PE). Included in the study were patients who had undergone elective and traumatic foot and ankle surgery from June 2017 to December 2018. Using retrospective data obtained we compared patient demographics, surgery type, length of tourniquet time, postoperative immobilization, type of VTE prophylaxis, and comorbidities including history of smoking, peripheral vascular disease, bleeding disorders, and patients undergoing dialysis. Five of 425 (1.2%) patients were diagnosed with a deep vein thrombosis and 1 of 425 (0.2%) patients was diagnosed with a pulmonary embolism. Risks factors statistically significant for developing a VTE in our patient population included extended periods of immobilization and an increasing patient age. We were able to conclude that routine prophylaxis for elective and traumatic foot and ankle surgery is both effective and safe for especially in older patients requiring extended immobilization. It's also important to take into consideration comorbidities, smoking history, tourniquet time, and the type of surgery that is being performed.

Development of the Plymouth VTE Risk Score for patients treated with lower limb immobilisation in a cast or boot. Injury 2021; 52:3277-3285.

Abstract
There is approximately a 2% risk of clinically significant VTE following temporary lower limb immobilisation after injury with an ankle immobilising plaster cast or boot. There is evidence that thromboprophylaxis for lower limb immobilised patients reduces the risk of VTE by approximately 50% but there is no international consensus as to which patients should receive thromboprophylaxis. The Plymouth VTE Risk Score was developed to identify patients at particular risk of VTE, in order to offer chemical prophylaxis to reduce their VTE risk. The score showed high completion rates, reliability and consistency. Using the Plymouth VTE Risk Score Version 3 (2014), we found an incidence of clinical VTE of 0.36% with 37.6% of patients being advised to have thromboprophylaxis. This is a lower VTE incidence than in most other studies of this patient group, which is of the order of 2 to 3%. The optimal RAM to use in clinical practice is yet to be defined, further clinical research is needed to accurately stratify patient risk and to define optimal risk treatment levels. We suggest research should focus on comparative clinical studies of risk assessment models.

Abstract
This systematic review was conducted to investigate the effects of currently used chemoprophylactic modalities to assess concerns regarding their usage. Preventive benefits of thromboprophylaxis were weighed against potential complications in orthopedic and trauma patients. The Ovid MEDLINE® database was used to identify relevant studies. The authors independently screened the initial study articles by title and abstract, eliminating articles not dealing with venous thromboembolism (VTE) chemoprophylaxis in orthopedic or trauma populations. The remaining articles were assessed for eligibility through full-text analysis. The analyzed studies within this review suggested that Factor Xa inhibitors and direct oral anticoagulants hold promise as safe and potentially more effective thromboprophylactic entities when compared to low molecular weight heparin in trauma and orthopedic patients. Thromboprophylaxis had little to no effect on major bleeding incidence, although we could not definitively conclude there was no effect on overall bleeding. Early thromboprophylaxis, especially when identifiable risk factors are present, can improve VTE prevention without changing major bleeding rates. Additionally, we could not conclude whether extended prophylaxis affects VTE incidence, although it seemed to have no effect on major bleeding. Finally, we determined that thromboprophylaxis in the lower extremity trauma population is questionable without the presence of underlying risk factors.

Abstract
Background There is still a lack of data on deep vein thrombosis (DVT) following surgically treated femoral shaft fracture (FSF). The goal of this study was to investigate the characteristics of postoperative DVT and the association between the occurrence of DVT and risk factors in patients undergoing surgical treatment for FSF. Methods This observational retrospective case-control study reviewed 308 patients who received surgical treatment of FSF between January 2016 and October 2020 at a university hospital. Univariate analyses were performed on the data of demographics, comorbidities, laboratory biomarkers, and operation-related indexes. The receiver operating characteristic (ROC) curve analysis, univariate analyses, and multivariate logistic regression analysis were employed to identify the independent risk factors associated with DVT. Results In total, 308 patients with surgically treated FSF were included, among whom 48 (15.6%) patients had postoperative DVTs. The univariate analyses showing significant differences regarding DVT were American Society of Anesthesiologists (ASA) classification, diabetes mellitus, current smoking, aspartate transaminase (AST), and very-low-density lipoprotein (VLDL) level among the 34 factors. According to the ROC results, the optimal cutoff values for intraoperative blood loss, d-dimer, and age were 350 ml, 1.08 μg/ml, and 35 years, respectively. The multivariable model demonstrated 4 significantly independent associations with postoperative DVT, including current smoking, intraoperative blood loss (> 550 ml), age (> 35 years), and d-dimer > 1.09 μg/ml. Conclusion These risk factors as screening tools contribute to risk stratification of the occurrence of thromboembolic events. In addition, our findings would help orthopedic surgeons make a cross-specialty decision and implement targeted precaution measures for patients with FSF.

Abstract
BACKGROUND Deep venous thrombosis (DVT) is the most common complication in patients with traumatic fractures. The neutrophil extracellular traps (NETs) can promote thrombus formation. In this prospective study, we investigated the role of NETs in thrombosis in patients with traumatic fractures to evaluate whether the biomarkers of NETs can be used to help predict the risk of thrombosis. METHODS Traumatic fracture patients were enrolled in this prospective observational cohort study. Healthy controls (Control); patients with lower extremity fractures who neither present with nor develop DVT (Trauma non-DVT); patients with lower extremity fractures who do not present with DVT but do develop DVT (Trauma DVT); and patients with lower extremity fractures who present with DVT (DVT) were included. NETs biomarker levels of Citrullinated Histone H3 (H3Cit), cell-free DNA (cfDNA) and nucleosomes in the plasma were determined. The D-dimer and fibrin(-ogen) degradation products (FDP) level in plasma was measured. Statistical analysis of the test results was performed to assess changes in NETs biomarker levels during thrombosis in patients with traumatic fractures. RESULTS The H3Cit levels in the DVT group were significantly greater than in the Trauma non-DVT group and Trauma DVT group (1.88(1.11, 3.35) ng/ml Vs 0.38(0.10, 1.17) ng/ml, P ≤ 0.05). The level of cfDNA was significantly greater in patients with traumatic fractures and was higher after thrombosis than before. The levels of D-dimer in the DVT, Trauma DVT, and Trauma non-DVT groups were significantly greater than in the Control group (5.11(3.97, 8.11) mg/l; 6.12(2.59, 18.49) mg/l; 2.99(0.99, 9.02) mg/l Vs 0.18(0.08,0.24) mg/l, P < 0.05). The distribution of FDP levels in each group was similar to that of D-dimer. Data are presented as medians (25th percentile, 75th percentile). CONCLUSIONS NETs released by neutrophils are involved in the formation of DVTs in patients with traumatic fractures. H3Cit and cfDNA can assist the diagnosis of DVT in patients with traumatic fractures.

Abstract
Introduction: There is increasing interest in the early identification and treatment of adverse medical events following orthopaedic procedures. The purpose of this study is to characterize the timing of 8 early adverse events following open reduction and internal fixation of closed fractures of the ankle. Methods: A retrospective cohort study was conducted using the American College of Surgeons National Surgical Quality Improvement Program. A total of 17 318 patients undergoing open reduction and internal fixation of closed ankle fractures were identified. 48.4% of patients were discharged on the day of surgery. For each of 8 different early adverse events, the median postoperative day of diagnosis, interquartile range for day of diagnosis, and middle 80% for day of diagnosis were determined. Timing was compared between unimalleolar and bi-/trimalleolar fractures and between inpatient and outpatient procedures. Results: The median day of diagnosis (and interquartile range; middle 80%) for myocardial infarction was 2 (1-5; 0-17), pneumonia 3 (2-7; 1-19), acute kidney injury 6.5 (2-18; 2-20), urinary tract infection 7 (2-14; 0-24), pulmonary embolism 10 (3-21; 0-27), sepsis 15 (4-22; 1-28), deep vein thrombosis 17 (10-22; 3-27), and surgical site infection 19 (14-25; 8-28). Patients with bi-/trimalleolar fractures had earlier occurrence of myocardial infarction (day 2 vs 10), urinary tract infection (day 6.5 vs 9.5), and sepsis (day 10 vs 20.5). Inpatients had later occurrence of acute kidney injury (day 7 vs 3), but earlier occurrence of urinary tract infection (day 6 vs 15). Conclusions: These precisely described time periods for occurrence of specific adverse events enable heightened awareness among orthopaedic surgeons during the first month following open reduction and internal fixation of the ankle. Orthopaedic surgeons should have the lowest threshold for testing for each adverse event during the time period of greatest risk.Levels of Evidence: Therapeutic, Level III: Retrospective cohort study.

Abstract
To investigate the incidence and location of deep vein thrombosis (DVT) in patients with lower extremity fractures receiving pharmacological thromboprophylaxis with LMWH followed by rivaroxaban. All patients aged ≥18 years with lower extremity fractures were included in the study. Duplex ultrasonography (DUS) was performed in the lower extremities before and after surgery for DVT evaluation. According to the location, the DVT was divided into proximal, distal, and mixed thromboses. According to fracture location, patients were classified as having fractures proximal, around, and distal to the knee. All patients received sequential chemical prophylaxis. A total of 404 patients with a mean age of 44.2 ± 13.8 years were included. The incidence of DVT postoperatively was higher than that preoperatively and at 1 month postoperatively. Patients with fractures proximal and around the knee had higher DVT incidences detected on DUS postoperatively and at 1 month postoperatively. Most DVTs were located in the distal vein. DVT incidence and severity were the highest immediately after surgery. DVT incidence in fractures around and proximal to the knee increased after surgery and at 1 month postoperatively. Although with chemical thromboprophylaxis, distal DVT was the most variable during the early stage.

Abstract
This study aimed to investigate deep vein thrombosis (DVT) in patients with lower extremity fractures who received anticoagulation treatment in the perioperative stage. We collected the patients’ clinical data and diagnosed DVT using Doppler ultrasonography. Preoperative, postoperative, and 1-month postoperative examinations were performed. The patients were divided into thrombosis and non-thrombosis groups according to ultrasonographic findings. A total of 404 patients were included in the study. The preoperative, postoperative, and 1-month postoperative incidence rates were, respectively, 35%, 55%, and 40% for DVT and 12%, 22%, and 20% for DVT in the uninjured contralateral lower extremity. The incidence of perioperative DVT decreased over time from 223 (55%) to 161 (40%). Multivariate analysis revealed that the independent risk factors for preoperative that of DVT were age (odds ratio [OR]: 1.03; 95% CI: 1.01-1.04; P = .000); postoperative that of DVT were age (OR: 1.04; 95% CI: 1.03-1.05; P = .000), blood loss (OR: 1.001; 95% CI: 1.000-1.002; P = .018), and American Society of Anesthesiologists classification (OR: 2.07; 95% CI: 1.16-3.72; P = .014); and 1-month postoperative that of DVT were age (OR: 1.05; 95% CI: 1.03-1.07; P = .000), respectively. In conclusion, the incidence of perioperative DVT decreased over time in patients who received anticoagulation treatment. Age was an important risk factor for perioperative DVT.

Abstract
Background Limited information exists on the incidence of postoperative deep venous thromboembolism (DVT) in patients with isolated patella fractures. The objective of this study was to investigate the postoperative incidence and locations of deep venous thrombosis (DVT) of the lower extremity in patients who underwent isolated patella fractures and identify the associated risk factors. Methods Medical data of 716 hospitalized patients was collected. The patients had acute isolated patella fractures and were admitted at the 3rd Hospital of Hebei Medical University between January 1, 2016, and February 31, 2019. All patients met the inclusion criteria. Medical data was collected using the inpatient record system, which included the patient demographics, patient’s bad hobbies, comorbidities, past medical history, fracture and surgery-related factors, hematological biomarkers, total hospital stay, and preoperative stay. Doppler examination was conducted for the diagnosis of DVT. Univariate analyses and multivariate logistic regression analyses were used to identify the independent risk factors. Results Among the 716 patients, DVT was confirmed in 29 cases, indicating an incidence of 4.1%. DVT involved bilateral limbs (injured and uninjured) in one patient (3.4%). DVT involved superficial femoral common vein in 1 case (3.4%), popliteal vein in 6 cases (20.7%), posterior tibial vein in 11 cases (37.9%), and peroneal vein in 11 cases (37.9%). The median of the interval between surgery and diagnosis of DVT was 4.0 days (range, 1.0-8.0 days). Six variables were identified to be independent risk factors for DVT which included age category (> 65 years old), OR, 4.44 (1.34-14.71); arrhythmia, OR, 4.41 (1.20-16.15); intra-operative blood loss, OR, 1.01 (1.00-1.02); preoperative stay (delay of each day), OR, 1.43 (1.15-1.78); surgical duration, OR, 1.04 (1.03-1.06); LDL-C (> 3.37 mmol/L), OR, 2.98 (1.14-7.76). Conclusion Incidence of postoperative DVT in patients with isolated patella fractures is substantial. More attentions should be paid on postoperative DVT prophylaxis in patients with isolated patella fractures. Identification of associated risk factors can help clinicians recognize the risk population, assess the risk of DVT, and develop personalized prophylaxis strategies.

Risk factors for symptomatic venous thromboembolism following surgery for closed ankle fractures: A case-control study. Foot Ankle Surg 2020; 26:681-686. [PMID: 31481323 DOI: 10.1016/j.fas.2019.08.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2019] [Revised: 07/19/2019] [Accepted: 08/19/2019] [Indexed: 02/04/2023]
Abstract
BACKGROUND We analyzed risk factors for venous thromboembolism (VTE) within 6 months after surgery for closed ankle fractures. METHODS This was a case-control study based on data from chart review in a cohort of patients having open reduction and internal fixation (ORIF) for closed ankle fractures in two large general hospitals 2009-2011. Cases with symptomatic VTE (pulmonary embolism or deep venous thrombosis) were identified in the cohort, and additional cases of VTE were identified by computerized search of discharge diagnoses in the same hospitals in 2004-2008 and 2012-2016. In total, we identified 60 cases with VTE and compared with 240 randomly selected controls among 998 patients without VTE in the cohort. Risk factors were assessed using logistic regression analysis. RESULTS Among cases, 27 (45%) had pulmonary embolism, 33 (55%) deep venous thrombosis. Those with VTE were older, had higher BMI, had more often a family history of VTE, and more often had antibiotic prophylaxis during surgery than controls. In multivariable logistic regression analysis age/10 (OR 25.75, 95%CI 3.52-188.44, p=0.001), (age/10)2 (OR 0.77, 95%CI 0.65-0.93, p=0.005), BMI (1.15 per kg/m2, 95%CI 1.07-1.24, p<0.001) and Charlson comorbidity index ≥2 vs.0 (OR 0.27, 95%CI 0.08-0.92, p=0.036) and 1 vs. 0 (OR 0.27, 95%CI 0.09-0.86, p=0.026) were associated with VTE within 6 months of surgery. CONCLUSIONS The odds of symptomatic VTE within 6 months of ORIF increased with increasing age and BMI, but were lower with increasing comorbidity.

Abstract
Background: Rates of deep venous thrombosis (DVT) have been studied for most common orthopaedic injuries. However, rates and risk factors have not been published for proximal hamstring injuries. Purpose: To determine the incidence of symptomatic DVT associated with proximal hamstring rupture and associations with prophylactic anticoagulation. Study Design: Case series; Level of evidence, 4. Methods: Inclusion criteria included all complete and, in a separate cohort, partial proximal hamstring ruptures treated by the senior author from 2007 through 2018 with at least 8 weeks of follow-up. Tendinopathy without tear was excluded. No DVT screening was performed. Charts of patients with symptomatic DVT were reviewed for the treatment method, the presence of imaging-confirmed DVT or pulmonary embolism, and risk factors for DVT. No patients received postinjury DVT prophylaxis. Surgical patients were routinely instructed to take aspirin (325 mg bid) or apixaban (2.5 mg bid) for 4 weeks. Patients with risk factors for DVT received enoxaparin (40 mg daily) for 2 weeks followed by aspirin (325 mg bid) for 2 weeks. Results: A total of 144 complete proximal hamstring ruptures were included: 132 treated operatively and 12 treated nonoperatively. There were 10 DVTs associated with the injury, for an overall rate of 6.9%. Five of the DVTs were diagnosed preoperatively in patients who had not received DVT prophylaxis; the other 5 were diagnosed postoperatively in patients on DVT prophylaxis. Six of the 10 DVTs had identifiable risk factors. All patients with postoperatively diagnosed DVTs were on prophylactic aspirin or enoxaparin. In the partial proximal hamstring rupture cohort of 114 ruptures, there were no DVTs. Conclusion: There is a high incidence of DVT associated with complete proximal hamstring ruptures (6.9%) despite many patients receiving DVT prophylaxis. This is substantially higher than that in other lower extremity injuries. Clinicians should have a high index of suspicion for DVT after these injuries, and postinjury DVT prophylaxis may be warranted.

Abstract
BACKGROUND Controversy remains regarding which patients with acute Achilles tendon rupture would best be treated nonoperatively and which might benefit from operative repair. The primary aim of this study was to characterize the overall incidence of-and specific risk factors associated with-postoperative complications that follow operative repair. We also evaluated the specific differences between complications after the use of an open or minimally invasive surgical (MIS) approach. METHODS Retrospective chart review identified 615 adult patients who underwent operative repair for an acute Achilles tendon rupture between January 1, 2001, and May 1, 2016, at 3 level I trauma centers. Minimum follow-up was 3 months. Patient demographics, comorbidities, injury mechanism, procedural details, and surgeon subspecialty were collected. Assessed complications included wound healing issues, rerupture, hematoma, nerve injury, deep vein thrombosis, and pulmonary embolism. RESULTS Seventy-two patients (11.7%) developed a postoperative complication. Risk factors included advancing patient age (odds ratio [OR], 1.04, P = .007), active tobacco use (OR, 3.20, P = .007), and specific subspecialty training (OR, 2.04, P = .046). No difference in overall complication rate was found between the open and MIS approaches (11.6% vs 13.2%, P = .658). A subgroup analysis among orthopedic subspecialties demonstrated that patients treated by trauma surgeons had increased rates of wound complication ( P = .043) and rerupture ( P = .025) compared with those treated by other subspecialties. Patients treated by trauma surgeons were also more likely to be younger or have a body mass index (BMI) > 30, although neither factor was found to be independently predictive for postoperative complications. CONCLUSION Approximately 1 in 9 patients undergoing operative repair of an acute Achilles tendon rupture developed a postoperative complication. Advancing age and active tobacco use were independent risk factors for developing such complications. Differences in subspecialty training also appear to impact complication rates, but the potential reason for this discrepancy remains unclear. As controversy remains regarding which patients who sustain acute Achilles tendon rupture should be treated nonoperatively and which would benefit most from surgical repair, a better understanding of postoperative complication rates and associated risk factors may enhance the decision-making processes in treating these injuries. It is not clear whether MIS techniques are superior to traditional open repair in terms of postoperative complications. LEVEL OF EVIDENCE Level III, retrospective comparative series.

Abstract
OBJECTIVE Explore the validity of the Caprini Score in orthopaedic patients with lower-extremity fractures. DESIGN Retrospective cohort study. SETTING Level I trauma academic medical center. PATIENTS/PARTICIPANTS Eight hundred forty-eight patients with lower-extremity fractures from 2002 to 2015 with exclusion criteria: minors, follow-up less than 30 days. INTERVENTION Stratify patients into 2 groups: high-risk (pelvic and acetabular fractures) and low-risk groups (isolated foot and ankle fractures). MAIN OUTCOME Caprini Score, fracture classification, length of follow-up, deep vein thrombosis (DVT) chemoprophylaxis, and venothromboembolism (VTE) events [DVT and/or pulmonary embolism (PE)] diagnosed with objective testing. RESULTS Eight hundred forty-eight patients (499 M; 349 F) 18-93 years of age (average 43.7) with average body mass index of 29. Three hundred high-risk and 548 low-risk patients with no differences in demographics with average follow-up of 288 days. There were 33 (3.9%) VTE events, which were more common in the high-risk group (8%: 9 DVT, 15 PE) than the low-risk group (1.6%: 8 DVT, 1 PE) (P < 0.0001). The cutoff that best-predicted VTE events based on receiver-operating curves was 12 (c = 0.74) in the high-risk group, 11 (c = 0.79) in the low-risk group, and 12 (c = 0.83) overall. CONCLUSION There was a significant lower VTE rate found in the low-risk group, but the Caprini prediction model was not significantly different between the 2 groups. This displays that patient factors play a large role in the development of VTE events independent of injury type. The Caprini score may help identify patients who may require increased protection.

Abstract
INTRODUCTION Among patients undergoing below-knee orthopaedic surgery, no consensus exists regarding the need for or type of postoperative prophylaxis to prevent venous thromboembolic (VTE) events. The purpose of this study was to assess the incidence and risk factors associated with symptomatic VTE among orthopaedic patients undergoing below-knee surgery who were subject to different types of pharmacologic thromboprophylactic strategies. METHODS A total of 20,043 adult patients who underwent surgery for a below-knee orthopaedic condition between August 2005 and August 2015 were identified. Retrospective chart review recorded patient demographics, comorbid data, and anatomic location of any procedures performed. Multivariable logistic regression analysis was used to determine factors associated with postoperative development of symptomatic VTE among patients receiving various thromboprophylactic regimens. RESULTS The incidence of symptomatic VTE in patients who underwent below-knee surgery was 2.5% (492/20,043). For patients who did not receive thromboprophylaxis, the incidence was 1.5% (134/9,127 patients). In this group, risk factors for developing VTE were male sex; nonwhite race; surgery performed below the knee but above the ankle; combination procedures of the forefoot/midfoot, hindfoot/ankle, and/or lower leg; history of VTE; and Charlson Comorbidity Index score greater than 2. Among patients who received an antiplatelet agent, the VTE incidence was 1.7% (33/1,992 patients). The incidence of VTE among patients who received an oral or injectable anticoagulant was 3.6% (325/8,924 patients). In this group, risk factors for developing VTE were male sex; surgery performed below the knee but above the ankle; combination procedures of the forefoot/midfoot, hindfoot/ankle, and/or lower leg; and history of VTE. CONCLUSION Allowing for different types of thromboprophylactic strategies, the results of this study demonstrate a higher rate of symptomatic thromboembolic disease compared with previously reported <1% VTE incidence rates among orthopaedic patients undergoing below-knee surgery. Certain patients are at higher risk for thromboembolic disease after below-knee orthopaedic surgery. This risk was not found to be lowered by thromboprophylaxis as performed in patients in this database. Future research should be directed at determining what the best thromboprophylactic strategies are for lowering this risk. LEVEL OF EVIDENCE Therapeutic study level III.

Abstract
BACKGROUND Currently, there is insufficient knowledge about the benefits of anticoagulant use for primary prevention of venous thromboembolism (VTE) and its inherent risk of bleeding adverse events in patients undergoing surgery distal to the knee. METHODS The study included patients who had undergone an orthopaedic procedure distal to the tibial articular surface when they were 18 years of age or older. Using retrospective information from a tertiary care referral center, we compared patient demographics, clinical findings, diagnostic reports, procedures performed, and the rate of symptomatic VTE and bleeding adverse events between patients who had and those who had not received anticoagulant prophylaxis. Propensity score matching was used to minimize selection bias due to prophylactic treatment allocation. RESULTS A total of 5,286 patients who had received anticoagulant prophylaxis for below-the-knee surgery were successfully matched with 5,286 patients who had not received anticoagulant prophylaxis for such surgery. After propensity score matching, the standardized difference between the groups was <0.1 for all baseline characteristics, indicating a negligible difference between the groups. Patients who received anticoagulant prophylaxis had a significantly lower risk of developing a VTE compared with patients who did not (39 patients [0.7%] versus 99 patients [1.9%]), with an odds ratio (OR) of 0.38 (95% confidence interval [CI], 0.25 to 0.56; p < 0.001). In contradistinction, patients who received anticoagulant prophylaxis had a significantly higher risk of developing a bleeding adverse event than those who did not (115 [2.2%] versus 55 [1.0%]; OR, 2.18 [95% CI, 1.55 to 3.09]; p < 0.001). CONCLUSIONS Anticoagulant prophylaxis reduced the risk of VTE after surgery distal to the tibial articular surface by 3-fold but resulted in a concomitant 2-fold increase in the risk of a bleeding adverse event. Large-scale, prospective studies are necessary to better understand the true incidence of such events, associated patient-specific risk factors, efficacy of various thromboprophylactic regimens, and patient-reported implications of such events.

Abstract
BACKGROUND: The incidence rate of venous thrombotic events (VTEs) following foot and ankle surgery is low. Currently, there is no consensus regarding postoperative prophylaxis or evidence to support risk stratification. METHODS: A 2-part study assessing the incidence and factors for the development of VTE was conducted: (1) a retrospective observational cohort study of 22 486 adults to calculate the overall incidence following foot and/or ankle surgery from January 2008 to May 2011 and (2) a retrospective matched case-control study to identify risk factors for development of VTE postsurgery. One control per VTE case matched on age and sex was randomly selected from the remaining patients. RESULTS: The overall incidence of VTE was 0.9%. Predictive risk factors in bivariate analyses included obesity, history of VTE, history of trauma, use of hormonal replacement or oral contraception therapy, anatomic location of surgery, procedure duration 60 minutes or more, general anesthesia, postoperative nonweightbearing immobilization greater than 2 weeks, and use of anticoagulation. When significant variables from bivariate analyses were placed into the multivariable regression model, 4 remained statistically significant: adjusted odds ratio (aOR) for obesity, 6.1; history of VTE, 15.7; use of hormone replacement therapy, 8.9; and postoperative nonweightbearing immobilization greater than 2 weeks, 9.0. The risk of VTE increased significantly with 3 or more risk factors ( P = .001). CONCLUSION: The overall low incidence of VTE following foot and ankle surgery does not support routine prophylaxis for all patients. Among patients with 3 or more risk factors, the use of chemoprophylaxis may be warranted. LEVEL OF EVIDENCE: Level III, retrospective case series.

Abstract
Total ankle arthroplasty has become an increasingly used alternative to ankle arthrodesis for the treatment of end-stage ankle arthritis. However, despite progressive technological advances and the advent of multiple commercial implant systems, some concern remains for the relatively high complication and failure rates. The objective of the present investigation was to perform a systematic review of the incidence of complications in obese patients undergoing total ankle arthroplasty. We performed a review of electronic databases with the inclusion criteria of retrospective case series, retrospective clinical cohort analyses, and prospective clinical trials with ≥15 total participants, a mean follow-up period of ≥12 months, ≥1 defined cohort with a body mass index of ≥30 kg/m2, and a reported incidence rate of complications requiring revisional surgery at the final follow-up point. Four studies met our inclusion criteria, with a total of 400 implants analyzed. Of these, ≥71 (17.8%) developed a complication requiring a revisional surgical procedure. The most commonly reported surgeries were revision of the metallic components and ankle gutter debridement. It is our hope that our investigation will allow foot and ankle surgeons to more effectively communicate the perioperative risk to their patients during the education and consent process.

Abstract
PURPOSE To determine perioperative incidence and locations of deep vein thrombosis (DVT) in injured and uninjured lower extremities following isolated lower extremity fractures (ILEFs). METHODS Retrospective analysis of a prospectively collected data of a consecutive patient series with ILEFs who underwent surgical treatment between September 2014 and September 2017 was performed. Patients' bilateral lower extremities were screened for DVT with duplex ultrasonography (DUS) before and after surgery. DVT occurrence was analyzed by location of DVT and fracture site. All patients received pharmacologic thromboprophylaxis while hospitalized. Data on demographics, time to surgery, time of DUS examinations, length of hospital stay and symptomatic pulmonary embolism (PE) was collected. RESULTS 1825 patients were included in the study. The incidence of symptomatic PE was 1.6%. All patients were screened with DUS of the bilateral lower extremities in a mean of 3.5 days (range: 0-18 days) after injury, and a mean of 3.6 days (range: 1-11 days) after surgery. Preoperative DUS detected DVT in 547 patients (30.0%), including 3.7% of patients with proximal DVT. 792 patients (43.4%) were found to have a DVT postoperatively, but only 6.2% of patients with proximal DVT. Proximal DVT was detected postoperatively of the represented fractures: 6.5% of the hip, 14.5% of the femoral shaft, 4.5% of the tibial plateau, 4.6% of the tibial shaft, 1.7% of the patellar, and 2.0% of the peri-ankle. Interestingly, the rate of DVT in an uninjured lower limb was significantly higher postoperatively compared to preoperatively (16.4% vs. 4.9%), however, only 0.2% of patients had proximal DVT. CONCLUSIONS While the perioperative incidence of overall DVT is high following ILEFs, the majority were distal DVT, and the rate of symptomatic PE was low. Femoral shaft fractures were associated with the highest incidence for proximal DVT. The incidence was lower in more distal fractures. The majority of patients diagnosed with DVT postoperatively had already shown symptoms of DVT prior to surgery. DVT can occur in both the injured and uninjured leg, with an obviously higher incidence in the injured leg. The incidence of proximal DVT in an uninjured leg is rare.

Abstract
There are limited data to guide the use of venous thromboembolism disease (VTED) prophylaxis after foot and ankle surgery. Although there is general consensus that the overall risk is lower than after hip or knee replacement, subpopulations of patients may be at relatively heightened risk. Furthermore, existing data are often conflicting regarding the efficacy of prophylaxis, with little acknowledgment of the tradeoffs between VTED prophylaxis and potential complications associated with the use of such medications. This article provides an overview of currently available evidence to guide decision making regarding VTED prophylaxis in patients who undergo foot and ankle surgery.

Abstract
The purpose of the present study was to determine whether certain foot/ankle surgeries would benefit from the routine use of low-molecular-weight heparin (LMWH) as postoperative deep venous thrombosis prophylaxis. We conducted a formal cost-effectiveness analysis using a decision analytic tree to explore the healthcare costs and health outcomes associated with a scenario of no prophylaxis and a scenario of routine LMWH prophylaxis for 4 weeks. The 2 scenarios were compared for 5 procedures: (1) Achilles tendon repair (ATR), (2) total ankle arthroplasty (TAA), (3) hallux valgus surgery (HVS), (4) hindfoot arthrodesis (HA), and (5) ankle fracture surgery (AFS). The outcomes assessed included short- and long-term costs, quality-adjusted life-years (QALYs), and incremental cost per QALY gained. The costs were evaluated from the healthcare system perspective and are expressed in U.S. dollars at a 2015 price base. In the short term, routine prophylaxis was always associated with greater costs compared with no prophylaxis. For ATR, TAA, HA, and AFS, prophylaxis was associated with slightly better health outcomes; however, the gain in QALYs was minimal compared with the cost of prophylaxis (incremental cost-effectiveness ratio well above $50,000/QALY threshold). For HVS, prophylaxis was associated with both worse health outcomes and greater costs. In the long term, routine prophylaxis was always associated with worse health outcomes and either cost more (HA, AFS, HVS) or saved very little (ATR, TAA). We concluded that policies encouraging the routine use of LMWH after foot/ankle surgery are unlikely to be cost-effective. Decisions to perform prophylaxis should be on a case-by-case basis and should emphasize individual patient risk factors.

Abstract
UNLABELLED Venous thromboembolism (VTE) is a well-known and feared complication following foot and ankle surgery, as it is a source of morbidity and mortality in the perioperative phase. The most recent CHEST guidelines recommended against the use of chemoprophylaxis and the majority of the literature has found a low incidence of VTE following foot and ankle surgery. Some authors prefer screening patients for risk factors and recommend the use of chemoprophylaxis on a case-by-case basis. Interestingly, studies that found high incidence of VTE were unable to determine a statistically significant difference between the prophylaxis and placebo groups. Major limitations of retrospective reviews is they are only able to study symptomatic VTE because no routine screening is typically performed. In a survey study, up to 98% of foot and ankle surgeons responded that they use prophylaxis in high-risk patients. Despite evidence-based recommendations, a significant number of foot and ankle surgeons are routinely using some form of VTE prophylaxis without taking risk factors into account.

Abstract
A wide range of factors contribute to the complexity of the management plan for an individual patient, and it is the surgeon's responsibility to consider the clinical variables and to guide the patient through the perioperative period. In an effort to address a number of important variables, the American College of Foot and Ankle Surgeons convened a panel of experts to derive a clinical consensus statement to address selected issues associated with the perioperative management of foot and ankle surgical patients.

Abstract
BACKGROUND Venous thromboembolic events (VTE) are a known and well-described complication following total knee arthroplasty (TKA). We sought to validate the American College of Chest Physicians thromboprophylaxis recommendations after elective TKA, paying special attention to our dose adjustments for weight, and their impact on VTE in our population. METHODS We retrospectively investigated risk factors in patients undergoing TKA, focusing mainly on symptomatic VTE occurrence rates from deep vein thrombosis (DVT) or pulmonary embolism (PE). The anticoagulation protocol consisted of starting low molecular-weight heparin (LMWH) therapy, with dalteparin administered 12 h after surgery in patients who received general anesthesia or 24 h later in patients who received single-dose regional anesthesia. RESULTS Data from 346 patients (mean age 66.8 [range 24-91] yr) who underwent primary or revision TKA depicted an overall symptomatic VTE rate of 15%. The proximal DVT rate was 1.7%, and the nonfatal PE rate was 0.9%. The mean time to VTE diagnosis was 5.6 days. The first dalteparin dose was administered 19.5 (range 10-48) h after surgery in patients without VTE and 22.6 (range 11.5-52) h after surgery in patients with VTE (p = 0.003). With a first dose of dalteparin administered 12 h postoperatively, patients presented significantly lower DVT and PE rates than if it was administered 24 h postoperatively (8.5% v. 16.3%, p = 0.048). CONCLUSION Delayed administration of LMWH has deleteriously impacted the VTE rate after TKA at our institution. Prompt initiation of LMWH (≤ 12 h after surgery) is appropriate, without increasing the risk of major bleeding.

Abstract
Ankle fractures requiring open reduction and internal fixation vary in severity from unimalleolar fractures to bimalleolar/trimalleolar (BT) fractures to pilon fractures. Consequently, the postoperative outcomes with these surgeries can vary. Most previous studies of these injuries had small sample sizes, studied a single risk factor or adverse event, or did not compare different injuries by severity. The purpose of the present study was to describe and compare the patient characteristics and postoperative outcomes of 2 high-energy ankle fractures: BT and pilon fractures. The relevant patients were identified from the American College of Surgeons National Surgical Quality Improvement Program database using the Current Procedural Terminology codes for BT and pilon fractures. Patient demographics, characteristics, comorbidities, and 30-day mortality and adverse events were recorded and compared between the 2 types of ankle fractures. More than 45% of patients with these fracture types were aged 40 to 65 years. Pilon fractures occurred more frequently in younger patients, were more likely to occur in men, required a longer hospital stay and operative time, were less likely to occur in patients with a body mass index of >30 kg/m2, and conferred a greater risk of wound complications (odds ratio 1.76; p = .048) compared with BT fractures. The findings from the present study help us understand the differences in patient characteristics and potential early adverse events after open reduction and internal fixation of BT fractures versus pilon fractures.

Abstract
OBJECTIVES This study examined the incidence and risk factors of preoperative deep vein thrombosis (DVT) in patients presenting to an outpatient setting with an isolated calcaneal fracture. DESIGN Retrospective chart review. SETTING All patients included in the study presented to the treating surgeon at a Level I trauma center with isolated calcaneal fractures as an outpatient between 2005 and 2013. METHODS These patients were either referred from outside hospitals, had been evaluated in the emergency department initially and presented for definitive care, or presented initially to the outpatient clinic. Patients included were over the age of 18, had a preoperative duplex ultrasonography of bilateral lower extremities per the treating surgeon's protocol, and had at minimum 6 weeks follow-up. Patients were excluded if they were a polytrauma, had a documented hypercoagulable state, or were on baseline pharmacologic anticoagulation for another condition. All patients had a preoperative duplex ultrasound of both lower extremities to evaluate for DVT at least 7 days after injury. MAIN OUTCOME MEASURE Patients found to have a preoperative DVT were compared with those who did not have preoperative DVT for possible risk factors. RESULTS One hundred fifty-nine patients qualified for our study and of these, 19 (12%) were found to have a DVT preoperatively, almost all of which were in distal veins. All risk factors, including age, sex, and body mass index were analyzed as continuous variables. Older age was found to be a risk factor for DVT (P = 0.009, Odds Ratio = 1.06, 95% CI, 1.01-1.11). All other predictor variables, including body mass index (P = 0.05) and sex (P = 0.08), were not statistically significant predictors in our sample. CONCLUSIONS The incidence of preoperative DVT found here is almost 2 times as high as any previously published examination of lower extremity injuries. Physicians should be aware of this increase so they may counsel patients about the risks of DVTs and the likelihood of any sequelae from developing a DVT that may affect a patient's recovery.

Abstract
The routine use of venous thromboembolism prophylaxis in patients undergoing foot and ankle procedures is not well supported in the literature. Multiple studies draw conclusions from heterogeneous populations, and specific studies have small numbers of specific pathologic conditions. Depending on the study, recommendations for and against venous thromboembolism prophylaxis in foot and ankle surgery can be made. The identification of risk factors for venous thromboembolism is paramount in the decision making of postoperative venous thromboembolism prophylaxis.

Abstract
PURPOSE To perform a meta-analysis investigating venous thromboembolism (VTE) following isolated foot and ankle surgery and propose guidelines for VTE prevention in this group of patients. METHODS Following a PRISMA compliant search, 372 papers were identified and meta-analysis performed on 22 papers using the Critical Appraisal Skills Programme and Centre for Evidence-Based Medicine level of evidence. RESULTS 43,381 patients were clinically assessed for VTE and the incidence with and without chemoprophylaxis was 0.6% (95% CI 0.4-0.8%) and 1% (95% CI 0.2-1.7%), respectively. 1666 Patients were assessed radiologically and the incidence of VTE with and without chemoprophylaxis was 12.5% (95% CI 6.8-18.2%) and 10.5% (95% CI 5.0-15.9%), respectively. There was no significant difference in the rates of VTE with or without chemoprophylaxis whether assessed clinically or by radiological criteria. The risk of VTE in those patients with Achilles tendon rupture was greater with a clinical incidence of 7% (95% CI 5.5-8.5%) and radiological incidence of 35.3% (95% CI 26.4-44.3%). CONCLUSION Isolated foot and ankle surgery has a lower incidence of clinically apparent VTE when compared to general lower limb procedures, and this rate is not significantly reduced using low molecular weight heparin. The incidence of VTE following Achilles tendon rupture is high whether treated surgically or conservatively. With the exception of those with Achilles tendon rupture, routine use of chemical VTE prophylaxis is not justified in those undergoing isolated foot and ankle surgery, but patient-specific risk factors for VTE should be used to assess patients individually.

Abstract
OBJECTIVE The purpose was to calculate the incidence rates and determine risk factors for 30-day postoperative mortality and morbidity after ankle fracture open reduction and internal fixation (ORIF). METHODS The NSQIP database was queried to identify patients undergoing ankle fracture ORIF from 2006 to 2011, with extraction patient-based or surgical variables and a 30-day clinical course. Multivariable logistic regression analysis identified significant predictors on outcome measures. RESULTS Mean age was 50.3 (±18.2) years while diabetes mellitus (12.8%) and body mass index ≥40 kg/m(2) (9.2%) were documented from a total of 3328 patients identified. The 30-day mortality rate was 0.30%, and complications occurred in 5.1%. Chronic obstructive pulmonary disease [odds ratio (OR): 4.23, 95% confidence interval (CI): 1.19-15.06] and a nonindependent functional status before surgery (OR: 2.25, 95% CI: 1.13-4.51) were the sole independent predictors of mortality and major local complications, respectively. Major local complications occurred in 2.2% of patients, and significant predictors were peripheral vascular disease (OR: 6.14; 95% CI: 1.95-19.35), open wound (OR: 5.04; 95% CI: 2.25-11.27), nonclean wound classification (OR: 3.02; 95% CI: 1.31-6.93), and smoking (OR: 2.85; 95% CI: 1.42-5.70). Independent predictors of hospital stay >3 days were cardiac disease, age 70 years or older, open wound, partially/totally dependent functional status, American Society of Anesthesiologists (ASA) classification ≥3, body mass index ≥40 kg/m(2), bimalleolar or trimalleolar ankle fracture pattern, female sex, and diabetes. CONCLUSIONS Chronic obstructive pulmonary disease increased the risk of mortality after ankle fracture ORIF. Risk factors for postoperative complications included peripheral vascular disease, open wound, nonclean wound classification, age 70 years or older, and ASA classification ≥3.

Abstract
Venous thromboembolism (VTE) is a well documented complication following lower limb trauma and surgery. The incidence of VTE in hip and knee surgery has been well studied, whereas the incidence in foot and ankle surgery is less clear. There is debate as to which cases require prophylaxis and what is the most effective means by which this is achieved. We performed a systematic review of the published English literature on VTE prophylaxis in foot and ankle surgery using MEDLINE, EMBASE, CINHAL, Cochrane Library, without date restrictions up to December 2012. From 988 citations, 25 papers fulfilled the inclusion criteria. Conclusions were drawn on the incidence (symptomatic and asymptomatic VTE), location (distal vs. proximal), associated risk factors, timing of VTE, role of mechanical and pharmacological prophylaxis and cost effectiveness of the treatment. Our review showed that the overall incidence of symptomatic VTE in foot and ankle surgery is low (0-0.55%). There is increased incidence in foot and ankle trauma patients with the highest incidence reported in tendo-achilles surgery. The reported risk factors include previous history of VTE, immobilisation, high BMI, age, co morbidities, contraceptive pill, and air-travel. There is a cumulative effect resulting in higher risk when two or more risk factors are present.

Abstract
BACKGROUND There is little evidence regarding the incidence of symptomatic venous thromboembolism (VTE) following total ankle arthroplasty (TAA) to allow formulation of treatment recommendations. The purpose of this study was to determine the incidence of symptomatic VTE events after TAA without use of chemoprophylaxis and to identify risk factors contributing to the occurrence of VTEs. METHODS We conducted a retrospective chart review of 637 patients (664 ankles) who received a TAA between May 2007 and January 2014 and had a minimum follow-up of 3 months. Chemoprophylaxis was prescribed only in the setting of a history of VTE or active coagulopathy. Patients were continued on chemoprophylactic agents if they were taking these medications preoperatively. A VTE event was defined when clinical signs and symptoms of deep venous thrombosis (DVT) were confirmed with use of Doppler ultrasonography or pulmonary embolism was confirmed with the use of a computed tomography scan. Routine screening for VTE was not performed. RESULTS The overall incidence of clinically detected VTE events was 0.60% (4/664), with 0.45% (3 patients) developing a DVT and 0.15% (1 patient) developing a nonfatal pulmonary embolism. Moreover, we identified a subset of 434 patients without identifiable preoperative risk factors who were not taking chemoprophylaxis preoperatively and were not prescribed chemoprophylaxis postoperatively. Two of these patients developed a DVT postoperatively (0.46%). Given the low incidence of clinically detected VTE, no significant correlation could be identified between the occurrence of VTE events and risk factors. CONCLUSIONS Our results suggest that clinically detectable VTE after TAA is uncommon. Patients without identifiable risk factors do not appear to require chemoprophylaxis following TAA. We recommend continuation of antiplatelet or anticoagulation therapy in patients who are taking these medications preoperatively and the initiation of chemoprophylaxis postoperatively in patients with known risk factors for VTE.

Abstract
BACKGROUND Ankle fractures are common, with an incidence of up to 174 cases per 100 000 adults per year. Their correct classification and treatment are of decisive importance for clinical outcome. METHOD Selective review of the literature. RESULTS Ankle fractures are initially evaluated by physical examination and then by x-ray. They can be classified according to either the AO Foundation (Association for the Study of Internal Fixation) or the Weber classification. Dislocated fractures need emergency treatment with immediate reduction; this is crucial for the prevention of hypoperfusion and nerve damage. Weber A fractures can usually be treated conservatively, while Weber B and C fractures are usually treated with surgery. An evaluation of the stability of the syndesmosis is important for anatomical reconstruction of the joint. Wound hematoma and wound-edge necrosis are the most common complications, and the postoperative infection rate is 2%. Up to 10% of patients develop ankle arthrosis over the intermediate or long term. CONCLUSION With properly chosen treatment, a good clinical outcome can be achieved. The long-term objective is to prevent post-traumatic ankle arthrosis. The evidence level for optimal treatment strategies is low.

Abstract
The purpose of this document is to provide guidance for physicians regarding the risk, prevention, and diagnosis of venous thromboembolism disease after foot and ankle surgery and while caring for lower extremity injuries that require ankle immobilization. A panel composed of all authors of this document reviewed the published evidence and, through a series of meetings, reached consensus regarding the viewpoints contained herein. We conclude that routine chemical prophylaxis is not warranted; rather, patients should be stratified and have a prevention plan tailored to their individual risk level. An effective venous thromboembolism prevention program is typically multimodal and focuses on addressing any modifiable risk factors, use of mechanical prophylaxis, early mobilization, and careful consideration of the use of chemical prophylaxis. The final decision regarding use and method(s) of prophylaxis adopted should be agreed upon by both the clinician and patient after a discussion of the potential benefits and harms as they relate to the individual. This should take place preferably during the preoperative visit or in the immediate post-injury setting, and it may need to be revisited during the course of care if the patient's risk level changes. Prompt recognition of the signs and symptoms of deep venous thrombosis following surgery or injury is important. Patients suspected of deep venous thrombosis should receive further work-up with either a D-dimer test or duplex venous ultrasound of the symptomatic leg, depending on their pretest probability for the disease. The latter can be determined using a validated clinical decision-making tool (e.g., Well's criteria).

Abstract
BACKGROUND Ankle fractures are among the most common lower limb fractures and they can cause significant detrimental effects on quality of life and work. OBJECTIVE The objective of the review was to evaluate if there is any advantage of early weight-bearing after open reduction and internal fixation of the ankle. METHODS Electronic databases, reference lists of included studies and relevant systematic reviews were searched for randomized and non-randomized controlled trials in adults comparing early and late weight-bearing after open reduction and internal fixation of the ankle. The search was inclusive up to February 2012. RESULTS Nine studies comprising 555 subjects were included for review. There were significantly better outcomes for improved early dorsiflexion, time to full weight-bearing, early return to previous work and shorter hospital stay (patient<60 years of age) in the early weight-bearing group. CONCLUSION The evidence base contained many methodological limitations and was generally poor, and so any conclusion drawn from the research must be done so with caution. The literature suggests that early weight-bearing may allow for quicker rehabilitation and earlier return to work. Future studies should focus on randomized controlled trials with narrow range of clinically useful outcome measures and consistent immobilization strategy between experimental groups.

Abstract
An increasing body of evidence has implicated obesity as having a negative effect on the development, treatment, and outcome of lower extremity pathologic entities, including diabetic foot disease. The objective of the present study was to increase the body of knowledge with respect to the effects of obesity on foot function. Specifically, we attempted to (1) describe the relationship between an increasing body mass index (BMI) on plantar foot pressures during gait, and (2) evaluate the efficacy of commonly prescribed off-loading devices with an increasing BMI. A repeated measures design was used to compare the peak plantar foot pressures under multiple test conditions, with the volunteers acting as their own controls. The primary outcome measure was the mean peak plantar pressure in the heel, midfoot, forefoot, and first metatarsal, and the 2 variables were modification of patient weight (from "normal" BMI to "overweight," "obese," and "morbidly obese") and footwear (from an athletic sneaker to a surgical shoe, controlled ankle motion walker, and total contact cast). Statistically significant increases in the peak plantar pressures were observed with increasing volunteer BMI weight class, regardless of the off-loading device used. The present investigation has provided unique and specific data with respect to the changes that occur in the peak plantar pressures with variable BMIs across different anatomic levels and with commonly used off-loading devices. From our results, we have concluded that although the plantar pressures increase with increasing weight, it appears that at least some reduction in pressure can be achieved with an off-loading device, most effectively with the total contact cast, regardless of the patient's BMI.

Abstract
Significant patient morbidity and mortality is associated with the development of venous thromboembolism (VTE) following orthopedic surgery. The majority of the literature supports proper prophylaxis following major orthopedic surgery involving hip and knee procedures. Foot and ankle surgery, however, is starkly contrasted because of the lack of recommendations. This article provides a comprehensive overview of the risk factors and incidence of VTE in foot and ankle surgery while also outlining the newest literature guidelines for prophylaxis.
