Abstract
Every surgeon may have experienced a tragic event associated with death or debilitation secondary to deep vein thrombosis (DVT) or pulmonary embolism (PE) after foot and ankle trauma and surgery. Nevertheless, the prevention of such a tragic event needs to be carefully evaluated rationally with currently available epidemiologic data. With great postoperative protocols and access to care, most PE events can be prevented. There are modifiable risk factors, such as length/type of immobilization and operative trauma/time that can lower the incidence of DVT/PE. In addition, chemical prophylaxis may be warranted in certain people within the foot and ankle trauma population.

Abstract
Athletes are among a unique group such that they may possess a serious underlying pathologic condition that may often go unnoticed given their high caliber of physical fitness. However, several considerations should be investigated, especially in the perioperative period, in order to minimize morbidity and mortality. Namely, cardiac pathologic condition can result in sudden death, and pulmonary pathologic condition may affect airway and respiratory management. Moreover, patients undergoing orthopedic surgery are at the highest risk for venous thromboembolism. Regardless of the condition, it is crucial to be vigilant and explore the unique medical considerations for the athlete undergoing anesthesia.

Low Response Rate to Follow-Up Using Telemedicine after Total Knee Replacement during the COVID-19 Pandemic in Italy. J Clin Med 2024; 13:360. [PMID: 38256494 PMCID: PMC10816610 DOI: 10.3390/jcm13020360] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Revised: 01/04/2024] [Accepted: 01/07/2024] [Indexed: 01/24/2024] Open
Abstract
BACKGROUND This study aimed to evaluate the survival rate and medium-term outcomes of patients after cemented posterior-stabilized (PS) mobile-bearing (MB) total knee arthroplasty (TKA) using a telemedicine platform during the COVID-19 pandemic in Italy. METHODS A total of 100 consecutive patients (mean age 73.5 ± 13.2 years) who received a cemented PS MB TKA were enrolled. The mean age of patients who did not complete the telemedicine follow-up (58%) was 75.8 ± 9.7 years. A dedicated software that makes it possible to perform video calls, online questionnaires, and acquire X-rays remotely was used. Subjective clinical scores and objective range-of-motion (ROM) measurements were observed at an average follow-up of 54 ± 11.3 months. RESULTS A total of 42 of 100 enrolled patients (mean age 70.3 ± 8.4 years) completed the telemedicine follow-up. The mean age of patients who did not complete the telemedicine follow-up (58%) was 75.8 ± 9.7 years. Age was found to be a statistically significant difference between the group that completed the telemedicine follow-up and the one that did not (p < 0.004). KOOS scores improved from 56.1 ± 11.3 to 77.4 ± 16.2, VAS scores decreased from 7.2 ± 2.1 to 2.8 ± 1.6, KSSf scores increased from 47.2 ± 13.3 to 77.1 ± 21.1, FJS scores improved from 43.4 ± 12.3 to 76.9 ± 22.9, and OKS scores increased from 31.9 ± 8.8 to 40.4 ± 9.9. All the differences were statistically significant (p < 0.05). The mean flexion improved from 88° ± 8° to 120° ± 12°. A radiographic evaluation showed a mean pre-operative mechanical axis deviation of 5.3 ± 8.0 degrees in varus, which improved to 0.4 ± 3.4 degrees of valgus post-operation. The survivorship at 5 years was 99%. CONCLUSIONS Subject to small numbers, telemedicine presented as a useful instrument for performing remote monitoring after TKA. The most important factor in telemedicine success remains the patient's skill, which is usually age-related, as older patients have much more difficulty in approaching a technological tool.

Abstract
Background Ankle fracture surgeries are generally safe and effective procedures; however, as quality-based reimbursement models are increasingly affected by postoperative readmission, we aimed to determine the causes and risk factors for readmission following ankle fracture surgery. Methods Ankle fracture cases were identified from the prospectively collected American College of Surgeons National Surgical Quality Improvement Program from 2013 to 2014. Demographics, comorbidities, and fracture characteristics were collected. Rates of 30-day adverse events and readmissions were determined as well as the causes for readmission. Multivariable logistic regression analyses were performed to identify risk factors associated with having any adverse events and being readmitted within 30 days of surgery. Results There were 5056 patients included; 167 (3.3%) were open fractures. The rate of any postoperative adverse event was 5.2%. There were 116 unplanned readmissions, with a readmission rate of 2.3%. Of the 116 unplanned readmissions, 49 (42.2%) were for reasons related to the surgery or surgical site, with the most common causes being deep surgical site/hardware infections (12.9%), superficial site infections (11.2%), and wound disruption (6.9%). Most readmissions were for reasons unrelated to the surgical site (51.7%), including cardiac disorders (8.6%), pulmonary disorders (7.8%), and neurological/psychiatric disorders (6.9%). The cause of readmission was unknown for 6% of readmissions. With multivariable logistic regression, the strongest risk factors for readmission were a history of pulmonary disease (odds ratio [OR], 2.29), American Society of Anesthesiologists (ASA) class ≥3 (OR, 2.28), and open fractures (OR, 2.04) (all P < .05). Conclusion In this cohort of 5056 ankle fracture cases, 2.3% of patients were readmitted within 30 days, with at least 51.7% of all unplanned readmissions due to causes unrelated to the surgery or surgical site. Predictors of readmission included a history of pulmonary disease, higher ASA class, and open fractures. Based on these findings, we advocate close medical follow-up with nonorthopaedic providers after discharge for high-risk patients. Level of Evidence Level III.

Abstract
BACKGROUND There is sparse data on the incidence of thromboembolic and medical complications following total ankle replacements. The aim of this systematic review was to determine the risk of deep vein thrombosis and pulmonary embolism as well as mortality and medical complications following ankle replacements. METHODS A systematic review was undertaken using all levels of evidence following PRISMA guidelines. Of the 1657 articles identified, 25 met the inclusion criteria. The inclusion criteria were a primary total ankle replacement with the recording of medical complications and/or thromboembolic events and/or mortality data. Two reviewers independently reviewed all articles. Quantitative methods were used to pool the percentages with complications across studies. RESULTS The pooled percentage with reported symptomatic deep vein thrombosis across 18 studies was 0.07% (95% CI 0.001%-0.59%). The pooled percentage with reported postoperative pulmonary embolism across 8 studies was 0.01% (95% CI 0.001%-0.03%). The pooled postoperative reported mortality was 0.06% (95% CI 0.001%-0.24%). Other medical complications had low incidences. CONCLUSION Our study indicates rates of reported thromboembolic events of less than 1 in 1000. Notably the level of evidence analyzed was mainly Level III and IV, likely underestimating the true incidence of these events because of recall and medical record limitations, and we had insufficient information on usage of chemoprophylaxis among these patients. LEVEL OF EVIDENCE Level IV, systematic review based on all levels of evidence including case series.

Abstract
Background We aimed to compare the clinical effectiveness, cost-effectiveness and complication rates of total ankle replacement with those of arthrodesis (i.e. ankle fusion) in the treatment of end-stage ankle osteoarthritis. Methods This was a pragmatic, multicentre, parallel-group, non-blinded randomised controlled trial. Patients with end-stage ankle osteoarthritis who were aged 50-85 years and were suitable for both procedures were recruited from 17 UK hospitals and randomised using minimisation. The primary outcome was the change in the Manchester-Oxford Foot Questionnaire walking/standing domain scores between the preoperative baseline and 52 weeks post surgery. Results Between March 2015 and January 2019, 303 participants were randomised using a minimisation algorithm: 152 to total ankle replacement and 151 to ankle fusion. At 52 weeks, the mean (standard deviation) Manchester-Oxford Foot Questionnaire walking/standing domain score was 31.4 (30.4) in the total ankle replacement arm (n = 136) and 36.8 (30.6) in the ankle fusion arm (n = 140); the adjusted difference in the change was -5.6 (95% confidence interval -12.5 to 1.4; p = 0.12) in the intention-to-treat analysis. By week 52, one patient in the total ankle replacement arm required revision. Rates of wound-healing issues (13.4% vs. 5.7%) and nerve injuries (4.2% vs. < 1%) were higher and the rate of thromboembolic events was lower (2.9% vs. 4.9%) in the total ankle replacement arm than in the ankle fusion arm. The bone non-union rate (based on plain radiographs) in the ankle fusion arm was 12.1%, but only 7.1% of patients had symptoms. A post hoc analysis of fixed-bearing total ankle replacement showed a statistically significant improvement over ankle fusion in Manchester-Oxford Foot Questionnaire walking/standing domain score (-11.1, 95% confidence interval -19.3 to -2.9; p = 0.008). We estimate a 69% likelihood that total ankle replacement is cost-effective compared with ankle fusion at the National Institute for Health and Care Excellence's cost-effectiveness threshold of £20,000 per quality-adjusted life-year gained over the patient's lifetime. Limitations This initial report contains only 52-week data, which must therefore be interpreted with caution. In addition, the pragmatic nature of the study means that there was heterogeneity between surgical implants and techniques. The trial was run across 17 NHS centres to ensure that decision-making streams reflected the standard of care in the NHS as closely as possible. Conclusions Both total ankle replacement and ankle fusion improved patients' quality of life at 1 year, and both appear to be safe. When total ankle replacement was compared with ankle fusion overall, we were unable to show a statistically significant difference between the two arms in terms of our primary outcome measure. The total ankle replacement versus ankle arthrodesis (TARVA) trial is inconclusive in terms of superiority of total ankle replacement, as the 95% confidence interval for the adjusted treatment effect includes both a difference of zero and the minimal important difference of 12, but it can rule out the superiority of ankle fusion. A post hoc analysis comparing fixed-bearing total ankle replacement with ankle fusion showed a statistically significant improvement of total ankle replacement over ankle fusion in Manchester-Oxford Foot Questionnaire walking/standing domain score. Total ankle replacement appears to be cost-effective compared with ankle fusion at the National Institute for Health and Care Excellence's cost-effectiveness threshold of £20,000 per quality-adjusted life-year gained over a patient's lifetime based on long-term economic modelling. Future work We recommend long-term follow-up of this important cohort, in particular radiological and clinical progress. We also recommend studies to explore the sensitivity of clinical scores to detect clinically important differences between arms when both have already achieved a significant improvement from baseline.

Abstract
BACKGROUND End-stage ankle osteoarthritis causes severe pain and disability. There are no randomized trials comparing the 2 main surgical treatments: total ankle replacement (TAR) and ankle fusion (AF). OBJECTIVE To determine which treatment is superior in terms of clinical scores and adverse events. DESIGN A multicenter, parallel-group, open-label randomized trial. (ISRCTN registry number: 60672307). SETTING 17 National Health Service trusts across the United Kingdom. PATIENTS Patients with end-stage ankle osteoarthritis, aged 50 to 85 years, and suitable for either procedure. INTERVENTION Patients were randomly assigned to TAR or AF surgical treatment. MEASUREMENTS The primary outcome was change in Manchester-Oxford Foot Questionnaire walking/standing (MOXFQ-W/S) domain scores between baseline and 52 weeks after surgery. No blinding was possible. RESULTS Between 6 March 2015 and 10 January 2019, a total of 303 patients were randomly assigned; mean age was 68 years, and 71% were men. Twenty-one patients withdrew before surgery, and 281 clinical scores were analyzed. At 52 weeks, the mean MOXFQ-W/S scores improved for both groups. The adjusted difference in the change in MOXFQ-W/S scores from baseline was -5.6 (95% CI, -12.5 to 1.4), showing that TAR improved more than AF, but the difference was not considered clinically or statistically significant. The number of adverse events was similar between groups (109 vs. 104), but there were more wound healing issues in the TAR group and more thromboembolic events and nonunion in the AF group. The symptomatic nonunion rate for AF was 7%. A post hoc analysis suggested superiority of fixed-bearing TAR over AF (-11.1 [CI, -19.3 to -2.9]). LIMITATION Only 52-week data; pragmatic design creates heterogeneity of implants and surgical techniques. CONCLUSION Both TAR and AF improve MOXFQ-W/S and had similar clinical scores and number of harms. Total ankle replacement had greater wound healing complications and nerve injuries, whereas AF had greater thromboembolism and nonunion, with a symptomatic nonunion rate of 7%.

Abstract
OBJECTIVE Venous thromboembolism (VTE) is an uncommon, but potentially morbid, complication following foot and ankle fractures. Current standard is to not administer thromboprophylaxis to patients with such injuries. Nonetheless, patient and fracture factors might affect this risk/benefit consideration. The goal of this study was to determine what patients are most at risk. METHODS The M53Ortho Pearldiver database was used to identify patients with fractures isolated to the foot and ankle that were treated non-operatively or operatively. Patients with pilon, other appendicular fractures remote from the foot and ankle, and other traumatic injuries were excluded. The 90-day occurrence of VTE was identified based on codes for deep vein thrombosis or pulmonary embolism. Characteristics of those patients who did and did not have VTEs were compared using chi-square analyses. Multivariate logistical regression was then performed to determined factors independently associated with VTE. Finally, timing of VTE relative to fracture was analyzed. RESULTS A total of 298,886 patients with isolated foot or ankle fractures were identified, of which 1,661 (0.56%) had VTE in the 90 days following fracture. In terms of timing, 27.3% occurred in the first week, and 49.8% occurred in the first three weeks. Independent risk factors for VTE included (in decreasing order):prior VTE (odd ratio [OR] = 25.44), factor V Leiden (OR = 24.34), active cancer (OR = 1.84), specific fracture relative to metatarsal fracture (multiple fractures [OR: 1.51], ankle fracture [OR = 1.51], and calcaneus fracture [OR = 1.24]), surgical treatment (OR = 1.41), male sex (OR = 1.19), greater Elixhauser index (OR = 1.05), and increasing age (OR:1.05 per decade) (p<0.05 for each). CONCLUSIONS The present study found that, although only 0.56% of isolated foot and ankle fractures had a VTE within ninety days. Defined risk factors, such as Factor V Leiden, prior VTE, surgical treatment, active cancer, specific fracture patterns, and surgical treatment significantly affected the odds of their occurrence.

A ten-year retrospective multicentre review of patient reported outcomes shows high satisfaction rates with podiatric surgery. J Foot Ankle Res 2022; 15:44. [PMID: 35650635 PMCID: PMC9159929 DOI: 10.1186/s13047-022-00546-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Accepted: 05/03/2022] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND Corrective surgery for hallux abducto valgus is one of the most performed elective procedures in foot and ankle practice. Numerous methods of surgical correction have been reported within the literature, with varying clinical and patient reported outcomes. This study reviews the patient experience and outcomes in five podiatric surgery centres using the scarf diaphyseal osteotomy. METHOD Patient reported outcome measures (PROMs) were captured using the Patient Satisfaction Questionnaire 10 (PSQ-10), part of the PASCOM-10 podiatric surgery audit tool. PROMs were collated across five hospital sites over a 10-year period. RESULTS Of 1351 patients reported during the period, 1189 had complete retrospective data. The most common patient aim of surgery was 'no/less pain' reported in 70% of patients. 96.8% of patients reported their original foot complaint as 'better' or 'much better' after surgery. 92.8% of patients reported their expectations had been met with 96.6% reporting they would have surgery again under the same conditions. 98.5% of patients noted that the risks, complications, and expectations had been discussed prior to surgery. The most common complication was metatarsal fracture (4.6%). CONCLUSION The scarf osteotomy (with or without an Akin phalangeal osteotomy) consistently showed high patient satisfaction with low complication rates using PSQ-10 and this information can be used as part of the pre-operative consenting process. Patient expectations for surgery were often achieved, which may be attributed to the pre-operative work up of the patient. Further investigation into this correlation is suggested. LEVEL OF CLINICAL EVIDENCE IV (retrospective review).

Abstract
Deep venous thrombosis (DVT) has been characterized by a disorder of venous return caused by abnormal blood clotting in deep veins. It often occurs in the lower limbs and is a common complication in orthopaedics. Therefore, relevant professional organizations domestic and overseas had formulated and constantly updated relevant guidelines to prevent the occurrence of DVT. According to the management strategy of the guidelines, the incidence of DVT can be significantly reduced. However, due to the variety of fractures types, the guidelines cannot expound precautions and characteristics of DVT for all fracture types at present, and there are other related unresolved problems. For example, there is still a lack of consistent optimal strategies for the management of DVT following isolated lower extremity fractures with a higher incidence. The best anticoagulant strategies for patients with upper limb fractures, pediatric fractures, and those combined with other injuries are rarely described in orthopaedic guidelines, but such fractures are common in clinical orthopaedics. The long‐term complications after DVT, such as post‐thrombotic syndrome, are not well‐understood. In the absence of clear guidance, orthopaedic surgeons often resort to empiric anticoagulation or conservative treatment, so the prevention effects of DVT are inconsistent. The purpose of this review is to summarize the characteristics of DVT events after isolated lower extremity fractures and to discuss the unsolved issues in the guidelines by reviewing the previous literature and tracing the history of DVT discovery, to provide more scientific and comprehensive recommendations for the prediction and prevention of DVT.

Abstract
Athletes are among a unique group such that they may possess a serious underlying pathologic condition that may often go unnoticed given their high caliber of physical fitness. However, several considerations should be investigated, especially in the perioperative period, in order to minimize morbidity and mortality. Namely, cardiac pathologic condition can result in sudden death, and pulmonary pathologic condition may affect airway and respiratory management. Moreover, patients undergoing orthopedic surgery are at the highest risk for venous thromboembolism. Regardless of the condition, it is crucial to be vigilant and explore the unique medical considerations for the athlete undergoing anesthesia.

Risk Factors for Short-Term Complication After Open Reduction and Internal Fixation of Ankle Fractures: Analysis of a Large Insurance Claims Database. J Foot Ankle Surg 2021; 59:239-245.

Abstract
Although fractures of the ankle are common injuries treated by surgical podiatrists and orthopaedic surgeons specializing in foot and ankle surgery, postoperative complications can occur, often imposing an economic burden on the patient. As health care in the United States moves toward value-based care, cost reduction has primarily focused on reducing complications and unplanned episodes of care. We used a large modern database of insurance claims to examine patterns of complications after open reduction internal fixation of ankle fractures, identifying diabetes mellitus and history of myocardial infarction as risk factors for postoperative infection within 30 days of surgery. Lateral malleolar repair was less likely to lead to infection, or need for repeated surgery, than was medial malleolar fracture repair. Diabetes mellitus, neuropathy, and chronic obstructive pulmonary disease were associated with development of postoperative cellulitis. Patients with a history of cerebrovascular accident were more likely to return to the emergency department or to have a pulmonary embolism. Male sex, presence of lupus, and increased age were associated with repeat surgery.

Abstract
BACKGROUND This study was designed to investigate the incidence and hematological biomarker levels that are associated with deep venous thrombosis (DVT) following closed foot fractures (except calcaneal fractures). METHODS A retrospective analysis of data on patients presenting with closed foot fractures (excluding the calcaneus) between October 2014 and December 2018 was conducted. Duplex ultrasonography was used to screen preoperative DVT of bilateral lower extremities. Data on demographics, comorbidities, types of fracture, and laboratory biomarkers at admission were collected. Univariate analyses and multivariate logistic regression analyses were carried out to determine the independent risk factors associated with DVT. RESULTS A total of 537 patients were included, among whom 28 patients had preoperative DVTs, indicating a crude incidence rate of 5.2%. In isolated closed foot fractures, DVT occurred in 12 (2.9%) out of 410 patients, while in patients with concurrent fracture in other locations, 16 (12.6%) out of 127 patients developed DVT. The average interval between fracture occurrence and diagnosis of DVT was 4.2 days (median, 2 days), ranging from 0 to 17 days. Twenty-four patients (85.7%) developed DVT in the injured extremity, 3 (10.7%) in the uninjured extremity, and 1 (3.5%) in bilateral extremities. Seven risk factors were identified to be associated with DVT, including alcohol consumption, concomitant other fractures, platelet distribution width (PDW) <12%, high-density lipoprotein cholesterol (HDL-C) <1.1mmol/L, serum alkaline phosphatase (ALP) >100 U/L, serum sodium concentration (Na+) <135 mmol/L, and D-dimer >0.5 mg/L. CONCLUSION Being aware of the prevalence of DVT in closed foot fractures can help physicians to carry out the overall assessment, risk stratification, and individual prevention programs.

Abstract
Venous thromboembolism (VTE) is among the most feared complications by orthopedists both for due to its potentially lethal outcome and the uncertainties related to its prevention. Despite the vast literature on VTE prevention in major orthopedic surgeries, little is known about it in ankle and foot procedures. In orthopedics, adequate thromboprophylaxis requires a careful assessment of the thrombotic and hemorrhagic risks based on the procedure to be performed, as well as and knowledge on anticoagulant agents. The presentis review has the goal of assessing the risk of developingdiscusses VTE risk assessment, the modalities of thromboprophylaxis modalities, and the drugs used, with an emphasis on foot and ankle surgeries.

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 There is hesitancy to administer nonsteroidal anti-inflammatories (NSAIDs) within the postoperative period following fracture care due to concern for delayed union or nonunion. However, aspirin (ASA) is routinely used for chemoprophylaxis of deep vein thrombosis (DVT) and is gaining popularity for use after treatment of ankle fractures. The current study examines the incidence of nonunion of operative ankle fractures and risk of DVT in patients who did and did not receive postoperative ASA. METHODS A retrospective chart review was performed on all patients treated between 2008 and 2018 for ankle fractures requiring operative fixation by three Foot and Ankle fellowship trained orthopaedic surgeons at a single institution. Demographics, preoperative comorbidities, and postoperative medical and surgical complications were compared between patients who did and did not receive ASA postoperatively. For both groups, union was evaluated by clinical exam as well as by radiograph, for those with 6-week, 12-week, or 24-week follow-up. RESULTS Five-hundred and six patients met inclusion criteria: 152 who received ASA and 354 who did not. Radiographic healing at six weeks was demonstrated in 95.9% (94/98) and 98.6% (207/210) respectively (p-value .2134). There was no significant difference in time to radiographic union between groups. The risk of postoperative DVTs in those with and without ASA was not significantly different (0.7% (1/137) vs 1.2% (4/323), respectively; p-value .6305). CONCLUSION Postoperative use of ASA does not delay radiographic union of operative ankle fractures or affect the rate of postoperative DVT. This is the first and largest study to examine the effect of ASA on time to union of ankle fractures. LEVEL OF EVIDENCE III.

Abstract
Hallux valgus surgery (HVS) is one of the most common orthopedic procedures, often occurring in older adults. Guidelines provide inconsistent recommendations about venous thromboembolism (VTE) prophylaxis after HVS and data are scarce regarding VTE presentation and outcomes in this population. We reported the clinical characteristics and outcomes of VTE following HVS among patients enrolled in Registro Informatizado Enfermedad TromboEmbolica (RIETE), a prospective multicenter VTE registry. We compared the findings with those of other patients in RIETE. Consecutive patients with VTE post HVS were included in the study. Baseline characteristics, administration of VTE prophylaxis prior to diagnosis, presenting symptoms and signs, risk factors for VTE, and 90-day outcomes including recurrent VTE, major bleeding and death were determined. A total of 54 patients with VTE post HVS were identified in RIETE [median age: 64 (interquartile range 56-71) years; 85.2% female] and were compared with 74,111 VTE patients who had not undergone HVS. Among those with VTE post HVS, 63.0% had received VTE prophylaxis, in contrast to 35.6% in the rest of the RIETE cohort. Simplified Pulmonary Embolism Severity Index was zero in 66.7% of the patients with pulmonary embolism post HVS and 33.3% of other RIETE patients (P = 0.011). Compared with other VTE patients, use of estrogens was higher in HVS group (13.0% vs 5.4%, P = 0.01). All patients with VTE post HVS (100%) and most of other VTE patients (99.6%) were treated with anticoagulation, most commonly with low-molecular weight heparins. In contrast to the rest of the patients in RIETE, the absolute number of all fatal and non-fatal outcomes at 90 days was zero in the post HVS group (i.e. no deaths, no recurrence of VTE, and no major bleeding). In a large registry of patients with VTE, all patients with VTE post HVS underwent anticoagulation. These patients had much better outcomes than the rest of VTE patients, with no deaths, recurrences or major bleeding events at 90-day follow-up.

Abstract
Background: Venous thromboembolism (VTE) is a rare but potentially lethal complication after orthopaedic foot and ankle surgery. The true incidence of VTE after orthopaedic foot and ankle surgery stratified by specific procedure has yet to be examined. The purpose of this study is to report the incidence of and identify risk factors for VTE in a large sample of patients receiving orthopaedic foot and ankle surgery. Methods: In this study, we retrospectively analyzed data from the National Surgical Quality Improvement Program 2006 to 2015 data files. The incidence of VTE was calculated for 30 specific orthopaedic foot and ankle surgeries and for 4 broad types of foot and ankle surgery. Demographic, comorbidity, and complication variables were analyzed to determine associations with development of VTE. Results: The overall incidence of VTE in our sample was 0.6%. The types of procedures with the highest frequency of VTE were ankle fractures (105/15 302 cases, 0.7%), foot pathologies (28/5466, 0.6%), and arthroscopy (2/398, 0.5%). Female gender, increasing age, obesity, inpatient status, and nonelective surgery were all significantly associated with VTE. Conclusion: Although VTE after orthopaedic foot and ankle surgery is a rare occurrence, several high-risk groups and procedures may be especially indicated for chemical thromboprophylaxis. Levels of Evidence: Level III: Retrospective, comparative study.

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 Approximately 9% of a trauma surgeon’s workload in the UK is managing ankle fractures. Following an ankle fracture immobilisation with a plaster cast or removable orthotic is usual. The aim of this research was to assess the feasibility of a large multi-centre randomised controlled trial (RCT) to evaluate the difference between plaster cast and a removable orthotic for the management of adults with an ankle fracture. Methods A feasibility randomised controlled trial was undertaken in a UK trauma hospital in adults with an ankle fracture for which the treating clinician would consider plaster cast a reasonable management option. Exclusions included open or pathological fracture, unable to adhere to trial procedures, had other lower limb injury or required close contact casting. Participants were randomised using an independent telephone service to receive either plaster cast or removable orthotic. The primary outcome was to determine the recruitment and follow-up rates at 6 weeks, 3 and 6 months to assess the feasibility of a full RCT. Results Eighty five eligible patients presented during the 10-month recruitment period, 50 consented. Two patients were randomised who did not fulfil the eligibility criteria (protocol deviations), and 1 patient from each group crossed over. Follow-up at each time point was 92% at 6 weeks; 74% at 3 months and 83% at 6 months. Conclusions Recruitment and follow-up data demonstrated feasibility of conducting a larger-scale randomised controlled trial. The distributional properties of the patient-reported outcome measures will be used to determine future sample sizes. Trial registrations This study is registered with the ISRCTN (ISRCTN17809322), assigned 5 November 2015 and approved by the NRES Committee (The Black Country, 15/WM/0340), protocol version 2.0 (17 November 2015). It is co-sponsored by the University Hospitals Coventry and Warwickshire NHS Trust and University of Warwick and funded by the NIHR Research for Patient Benefit (PB-PG-0614-34,009). The trial sponsors have no direct involvement in any aspects of study design, conduct or decision to submit the report for publication.

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 evidence regarding the prevalence of deep vein thrombosis (DVT) after foot and ankle surgery in elective patients that need to be 6 weeks non-weight bearing postoperatively is incomplete and has limitations. METHODS: The prevalence of DVT in 114 procedures involving the hindfoot and midfoot was determined using ultrasonographic surveillance at 2 and 6 weeks after surgery. RESULTS: The prevalence of DVT was observed to be 25.4%. The majority (68.9%) of DVTs were diagnosed at the ultrasonographic scan performed 2 weeks postoperatively. The remainder (31.1%) of DVTs were diagnosed at the 6-week postoperative ultrasonographic scan. At least 75% of the patients who had early and late DVT had no clinical symptoms or signs of DVT. The prevalence of DVT in clinically detectable patients was 6%. The average age of patients with early DVT was 62.2 years, significantly higher compared to those who had no DVT. The mean tourniquet time for patients with early DVT was 68.1 minutes, significantly higher compared to those without DVT. All DVTs detected were distal to the popliteal vein. CONCLUSIONS: The prevalence of clinically silent DVT was significantly higher than was previously thought. We believe this increased rate is directly attributable to the use of ultrasonographic surveillance postsurgery both at 2 and 6 weeks. The risk of DVT continued after the 2-week visit, and 30% of the DVTs were detected at the ultrasonographic scan at 6 weeks. LEVEL OF EVIDENCE: Level II, prospective cohort.

Abstract
Background Complications following orthopedic surgeries are undesirable and costly. A potential method to reduce these costs is to perform traditionally inpatient surgical procedures in the outpatient setting. The purpose of this study is to compare outcomes between inpatient and outpatient settings for elective foot and ankle surgeries using the National Surgical Quality Improvement Program (NSQIP) database. Methods Patients with Current Procedural Terminology (CPT) codes specific to orthopedic foot and ankle surgery were identified from the 2011-2015 American College of Surgeons NSQIP database. Demographics, comorbidities, and complications were compared between patients undergoing inpatient and outpatient procedures. Results Patients receiving inpatient surgery were significantly older and more frequently male. Black patients were significantly more likely to undergo inpatient surgery than outpatient surgery while white patients were significantly more likely to undergo outpatient surgery. Outpatients had a significantly higher mean body mass index (BMI) than inpatients. Smokers were at a significantly greater risk of undergoing inpatient surgery than outpatient surgery. Outpatients had significantly longer operative times, were more likely to receive general anesthesia, had a lower American Society of Anesthesiologists (ASA) class, were more likely to be functionally independent, and were less likely to expire postoperatively. Patients who received surgery as an inpatient were significantly more likely to have comorbidities as compared to outpatients. The overall risk of surgical complications was significant between groups with 8.6% in the inpatient group and 2.0% in the outpatient group. The overall risk of medical complications was 16.9% in the inpatient group and 1.7% in the outpatient group. Similar to the surgical complications, inpatients were significantly more likely to sustain each of the individual medical complications except for stroke/CVA and venous thromboembolism. Conclusions Outpatient management is associated with decreased postoperative complications in select patients. Performing more operations in the outpatient setting in select patients may be beneficial for cost reduction and patient satisfaction.

Abstract
BACKGROUND: The knee scooter is a commonly used mobility device in the setting of unilateral below-knee immobilization. The bent-knee posture has been shown to decrease venous flow in a seated position, but the knee scooter differs as the patient is weightbearing through the affected extremity. Our goal was to investigate the effects of knee scooter positioning on popliteal venous flow. METHODS: Duplex ultrasonography was performed to obtain venous diameter and flow velocity of the popliteal vein on healthy subjects over the age of 18 without immobilization. Measurements were performed on the left knee of each subject while standing and with the same knee flexed on the knee scooter, by 2 physicians trained in ultrasound techniques. Mean velocity, peak velocity, vessel diameter, and volumetric flow rate were calculated and t tests were performed for each variable. A power analysis was performed, determining that 9 subjects would provide 80% power with an alpha of 0.05. A total of 13 subjects participated in the study. Mean age was 33 (range 20-56) years, with 6 females and 7 males. RESULTS: Measurements of subjects while standing and on the knee scooter demonstrated a significant decrease in mean velocity (6.5 vs 3.2 cm/s, P < .01) and volumetric flow rate (227.8 vs 106.2 mL/min, P < .01) while subjects were using the scooter. Vessel diameter (0.82 vs 0.78 cm, P = .15) and peak velocities (19.8 vs 14.7 cm/s, P = .19) were not significantly different between standing and kneeling positions. CONCLUSION: Our findings demonstrated a statistically significant decrease in volumetric flow rate in subjects using a knee scooter device with a flexed knee. Although venous stasis is a known risk factor for DVT, flow rate thresholds for increased thrombus formation are not well defined. The duration of scooter use, or flexed knee positioning, may have some effect on the degree of stasis. This finding should caution orthopedists to consider the risk attributed to the knee scooter as part of their overall patient assessment. LEVEL OF EVIDENCE: Level II, therapeutic, comparative study.

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
Although rare, deep vein thrombosis (DVT) and pulmonary embolism remain a concern for foot and ankle surgeons. Most prophylactic measures against DVT formation are synthesized from orthopedic hip and knee data, and therefore the routine use of these recommendations may place patients at risk for complications associated with unnecessary prophylaxis. In this article we review and present the most current literature specific to venous thromboembolism (VTE) in foot and ankle surgery. It is clear that, given our current literature, a case-by-case approach for VTE prophylaxis should be used following foot and ankle surgery.

Abstract
The incidence of venous thromboembolic (VTE) events (deep vein thrombophlebitis [DVT] or pulmonary embolism [PE]) in foot and ankle trauma has been low, and the risk/benefit ratio associated with chemoprophylaxis is controversial. We compared the 90-day incidence of VTE events in 3 cohorts: group 1, tendo-Achillis (TA) ruptures managed with full weightbearing in a walker boot; group 2, ankle fractures immobilized non-weightbearing in a below-the-knee cast; and group 3, ankle fractures managed surgically, followed by non-weightbearing in a below-the-knee cast. Data were extracted from 2 prospectively collected trust databases for acute TA ruptures and ankle fractures. VTE risk was assessed using a U.K. national assessment tool. Chemoprophylaxis was prescribed for high-risk patients. The 90-day incidence of symptomatic VTE events was drawn from a trust-wide radiology database. In group 1 (n = 291), the incidence of VTE events was 4.8% (11 [3.8%] DVT, 3 [1.0%] PE) at a mean of 16.1 ± 6.8 days. In group 2 (n = 227), the incidence of VTE events was 2.2% (5 [2.2%] DVT) at a mean of 33.4 ± 11.3 days. In group 3 (n = 199), the incidence of VTE events was 3.0% (5 [2.5%] DVT, 1 [0.5%] PE) at a mean of 37.2 ± 14.2 days. Patients with symptomatic VTE events presented significantly earlier after acute TA rupture compared with after ankle fracture (p = .002). We found the overall incidence of VTE events in foot and ankle trauma was low, with a relatively greater incidence of symptomatic VTE events, which occurred earlier, in acute TA ruptures compared with ankle fractures.

Abstract
BACKGROUND In the present study, we aimed to inspect the correlation of interleukin-18 (IL-18) and high-sensitivity C-reactive protein (hs-CRP), if any present, with the occurrence of perioperative deep vein thrombosis (DVT) in patients suffering from an ankle fracture (AF). METHODS Sixty-seven AF patients with complicated DVT (DVT group) and 448 AF patients without DVT (non-DVT group) were enrolled in the present study. To begin with, hemorheological indexes were detected. Turbidimetric immunoassay and enzyme-linked immunosorbent assay were used for the determination of the expressions of hs-CRP and IL-18, respectively. Coagulation method was used to detect prothrombin time (PT), thrombin time (TT), fibrinogen, and activated partial thromboplastin time (APTT). Logistic regression analysis was used to analyze the independent risk factors for DVT occurrence in AF patients after operation. RESULTS The results revealed that the DVT group presented an increased expression of hs-CRP and IL-18 1 day before operation and 1, 3, and 7 days after operation in comparison with the non-DVT group. The DVT group also had increased levels of PT, APTT, and prolonged TT and fibrinogen at 3 and 7 days after operation compared to the non-DVT group. After operation, it was observed that the patients in the DVT group had increased plasma viscosity, whole blood reduced viscosity, red blood cell (RBC) aggregation index, RBC deformation index, erythrocyte sedimentation rate, and declined erythrocrit. The independent risk factors for the occurrence of DVT were identified to be high-energy injury, TT, fibrinogen, hs-CRP, and IL-18 in AF patients after operation. CONCLUSIONS Based on the results obtained from the study, it was concluded that AF patients with DVT have higher levels of IL-18 and hs-CRP expressions, which is associated with the occurrence and development of DVT. These results may be particularly useful for diagnosis and treatment on DVT occurrence in AF patients.

Abstract
Venous thromboembolism (VTE) is a serious complication during and after hospitalization, yet is a preventable cause of in-hospital death. Without VTE prophylaxis, the overall VTE incidence in medical and general surgery hospitalized patients is in the range of 10% to 40%, while it ranges up to 40% to 60% in major orthopaedic surgery. With routine VTE prophylaxis, fatal pulmonary embolism is uncommon in orthopaedic patients and the rates of symptomatic VTE within three months are in the range of 1.3% to 10%. VTE prophylaxis methods are divided into mechanical and pharmacological. The former include mobilization, graduated compression stockings, intermittent pneumatic compression device and venous foot pumps; the latter include aspirin, unfractionated heparin, low molecular weight heparin (LMWH), adjusted dose vitamin K antagonists, synthetic pentasaccharid factor Xa inhibitor (fondaparinux) and newer oral anticoagulants. LMWH seems to be more efficient overall compared with the other available agents. We remain sceptical about the use of aspirin as a sole method of prophylaxis in total hip and knee replacement and hip fracture surgery, while controversy still exists regarding the use of VTE prophylaxis in knee arthroscopy, lower leg injuries and upper extremity surgery.

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
OBJECTIVES Clinical practice has shifted from therapeutic anticoagulation of any lower extremity venous thromboembolism (VTE) to only thromboses with risk of proximal extension or embolization-clinically important VTE (CIVTE). Isolated operative fractures of the tibia or distal bone of the lower extremity are associated with low-to-intermediate VTE risk, and there is wide variability in the choice to anticoagulate as well as anticoagulant. We sought to evaluate the role for chemoprophylaxis of VTE and CIVTE in these injuries by meta-analysis of Level I evidence. DATA SOURCES Articles in English, Chinese, French, and German in MEDLINE, Biosis, and EMBASE from 1988 to 2016. STUDY SELECTION Randomized controlled trials describing chemoprophylaxis of VTE after operative management of fractures of the tibia and distal bones. Independent review of 1502 citations yielded 5 studies (1181 patients) meeting inclusion criteria. DATA EXTRACTION Chemoprophylaxis regimen, VTE, CIVTE, and major bleeding events were recorded. Study quality was assessed with regard to randomization, outcome assessment allocation and treatment concealment, and commercial funding. DATA SYNTHESIS A random-effects model meta-analysis determined that chemoprophylaxis with a low-molecular-weight heparin (LMWH) compared with placebo or no intervention significantly reduced the risk of any VTE [pooled relative risk (RR) = 0.696, 95% confidence interval (0.490-0.989), P = 0.043; homogeneity P = 0.818, I = 0%]. However, chemoprophylaxis with a LMWH compared with placebo did not significantly reduce the risk of CIVTE [RR = 0.865, 95% confidence interval (pooled RR = 0.112-3.863), P = 0.790; homogeneity P = 0.718, I = 0%]. No major bleeding events occurred. Funnel plots did not suggest publication bias. The number needed to treat was 31 patients treated with chemoprophylaxis using a LMWH to prevent 1 VTE and 584 patients to prevent 1 CIVTE. CONCLUSIONS Meta-analysis of Level I evidence suggests that routine postoperative anticoagulation after surgical management of an isolated fracture of the tibia or distal bone in patients without risk factors for VTE is unlikely to provide a clinical benefit, based on the absence of a treatment effect for preventing VTE warranting therapeutic anticoagulation. LEVEL OF EVIDENCE Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Abstract
INTRODUCTION Historically, Achilles tendon repairs and other surgeries about the hindfoot have demonstrated a significantly higher rate of wound healing complications and surgical site morbidity. The purpose of this study was to evaluate the comprehensive complication profile and risk factors for adverse short-term, clinical outcomes after primary repair of Achilles tendon ruptures. METHODS Between the years 2005 and 2014, all cases of primary Achilles tendon repair (Current Procedural Terminology code 27650) entered into the National Surgical Quality Improvement Project (NSQIP) database were extracted for analysis. Primary outcomes of interest were rates of total complication, reoperation, and rerupture within 30 days of index surgery. Independent risk factors associated with these selected endpoints were assessed with chi-square and logistic regression analysis and odds ratios with 95% confidence intervals were used to express relative risk. RESULTS Of 1626 patients with an average age of 44 years (SD 13.3), the average ASA classification was 1.69 and hypertension (20.7%), morbid obesity (8.3%), and diabetes (4.9%) were among the most common medical comorbidities. A total of 28 (1.7%) patients sustained perioperative complications, including 1.3% with local complications (0.7% superficial wound infection, 0.4% wound disruption) and no cases of peripheral nerve injury or early repair failure. Systemic complications occurred in 0.4%, most commonly with deep venous thrombosis or nonfatal thromboembolism. Preoperative albumin was independently associated with an increased risk of local wound complications (odds ratio [OR] 28.67; 95% CI 1.42-579.40; P = .029). Chronic obstructive pulmonary disease (OR 22.33, 95% CI 2.49-199.81; P = .006) and bleeding disorder (OR 14.83, 95% CI 1.70-129.50; P = .015) were more likely to result in a systemic complication, and preoperative creatinine correlated with an increased risk of any complication (OR 6.11, 95% CI 1.15-32.34; P = .033). In total there were 5 (0.3%) readmissions with 2 (0.1%) unplanned reoperations attributed to local wound complications. CONCLUSION Among a broad-based demographic of the United States, the rate of local wound complications was exceedingly low in the short-term perioperative period, although this risk may be significantly magnified with subtle decreases in albumin levels. Preoperative risk stratifications should carefully scrutinize for subtle abnormalities in nutritional parameters and renal function prior to undergoing Achilles surgery. LEVELS OF EVIDENCE Therapeutic, Level II: Prospective, comparative trial.

The use of foot pumps compression devices in the perioperative management of ankle fractures: Systematic review of the current literature. Foot (Edinb) 2017; 31:61-66. [PMID: 28549283 DOI: 10.1016/j.foot.2017.03.002] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2016] [Revised: 01/27/2017] [Accepted: 03/05/2017] [Indexed: 02/04/2023]
Abstract
BACKGROUND Ankle fractures account for 9% of all fractures seen in the United Kingdom. 15,000 of these fractures undergo operative fixation each year. Soft tissue swelling impacts on timing of fixation due to fears of infection and wound dehiscence. The use of arterio-venous foot pumps (AVFP) is increasing in this population although the evidence for their efficacy is unclear. In order to address this, we present an overview of the evidence for AVFP device use following ankle fracture. METHODS In September 2015 an electronic literature search was undertaken of studies comparing two or more methods of swelling reduction in patients with ankle fractures. Of 326 screened, 5 papers ultimately were included. RESULTS Two studies reported a statistically significant reduction in swelling (p=0.03) and (p=0.03 at 24 hours, p=0.05 at 48 hours) after using AVFP devices compared to the controls (leg elevation +/ ice therapy). Stockle et al. reported a greater reduction in the preoperative ankle, midfoot and forefoot circumference at 24 hours in their AVFP group (53% versus 32% and 10% in their continuous cryotherapy and cool pack cryotherapy groups respectively). Whereas, Rohner-Spengler et al. observed improved preoperative swelling reduction in patients treated with a multilayer compression bandage when compared to their AVFP group. Keehan et al. reported that time to surgery was considerably reduced in patients treated with an AVFP device, (2.3 days) compared to those treated with leg elevation (4.6 days) (p=0.02). Length of stay (LOS) was not influenced by any of the tested interventions. CONCLUSIONS AVFP devices have been shown to reduce time to surgery and degree of swelling before operative intervention better than other methods but the strength of evidence to support this remains poor.

Abstract
Background: Ankle fracture surgeries are generally safe and effective procedures; however, as quality-based reimbursement models are increasingly affected by postoperative readmission, we aimed to determine the causes and risk factors for readmission following ankle fracture surgery. Methods: Ankle fracture cases were identified from the prospectively collected American College of Surgeons National Surgical Quality Improvement Program from 2013 to 2014. Demographics, comorbidities, and fracture characteristics were collected. Rates of 30-day adverse events and readmissions were determined as well as the causes for readmission. Multivariable logistic regression analyses were performed to identify risk factors associated with having any adverse events and being readmitted within 30 days of surgery. Results: There were 5056 patients included; 167 (3.3%) were open fractures. The rate of any postoperative adverse event was 5.2%. There were 116 unplanned readmissions, with a readmission rate of 2.3%. Of the 116 unplanned readmissions, 49 (42.2%) were for reasons related to the surgery or surgical site, with the most common causes being deep surgical site/hardware infections (12.9%), superficial site infections (11.2%), and wound disruption (6.9%). Most readmissions were for reasons unrelated to the surgical site (51.7%), including cardiac disorders (8.6%), pulmonary disorders (7.8%), and neurological/psychiatric disorders (6.9%). The cause of readmission was unknown for 6% of readmissions. With multivariable logistic regression, the strongest risk factors for readmission were a history of pulmonary disease (odds ratio [OR], 2.29), American Society of Anesthesiologists (ASA) class ≥3 (OR, 2.28), and open fractures (OR, 2.04) (all P < .05). Conclusion: In this cohort of 5056 ankle fracture cases, 2.3% of patients were readmitted within 30 days, with at least 51.7% of all unplanned readmissions due to causes unrelated to the surgery or surgical site. Predictors of readmission included a history of pulmonary disease, higher ASA class, and open fractures. Based on these findings, we advocate close medical follow-up with nonorthopaedic providers after discharge for high-risk patients. Level of Evidence: Level III.

Abstract
BACKGROUND Patient feedback is increasingly important to inform and develop effective healthcare within the United Kingdom. In order to optimise patient experience of ankle fracture care in our unit, we sought to identify elements of practice associated with poor patient experience and low levels of satisfaction. METHODS Adult patients with closed ankle fractures requiring fixation over a ten month period were prospectively identified. Prior to discharge all patients completed the Picker Patient Experience Questionnaire (PPE-15), satisfaction visual analogue scale (VAS: 0-10) and a demographic questionnaire. Operative delay and cancellation episodes were similarly noted. PPE-15 and satisfaction VAS data were collected concurrently from a control group of elective hip and knee arthroplasty patients. RESULTS 52 patients (23 males) of average age 47 years (17-86) underwent ankle fracture fixation. Median pre-operative length of stay (LOS) was 3days (IQR 1-6). Ankle fracture patients had significantly worse experiences compared to arthroplasty patients (p<0.05 across all 15 PPE domains). Once pre-operative length of stay exceeded 3days patients reported more areas of concerns (6 of 15) than those waiting 3days or less (4 of 15) (p=0.02). Cancelled patients reported significantly worse experiences, with satisfaction VAS of 7 (versus 9 in those not cancelled [p=0.005]), and median of 6 PPE-15 domains of concern (versus 3.5 [p=0.03]). CONCLUSIONS Efforts to improve the healthcare experience of patients with ankle fractures should be focused on improving processes that minimise cancellation of surgery and the communication around delay management.

Abstract
Controversy exists regarding the routine use of chemical prophylaxis in isolated lower extremity fractures. The incidence of VTE in specific fracture locations in the lower extremity is largely unknown, and represents key information necessary to determine the need for prophylaxis. A large cross-sectional study using the National Trauma Databank was performed evaluating for the incidence and risk factors of VTE in isolated tibia fractures. The overall incidence of DVT and PE are extremely low in cases of isolated tibia fractures, which brings into doubt a role for routine use of chemical prophylaxis for these fractures.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a well-documented complication in patients with lower limb fractures, but management guidelines for its prevention in isolated foot and ankle fracture patients are conflicting. The aim of this study was to conduct a multicenter, prospective cohort study to define the prevalence of VTE in patients with isolated foot and ankle fractures and determine whether routine prophylaxis is necessary in these patients. METHODS In a double-blind, placebo-controlled study, consecutive patients in 3 hospitals who met our criteria were enrolled. After randomization, patients received either thromboprophylaxis with low-molecular-weight heparin units (LMWH group) or placebo (placebo group) for a period of 2 weeks. All patients underwent routine ultrasonography 1 day preoperatively, 1 week postoperatively, and 1 month postoperatively. Demographic parameters were then collected and compared. RESULTS Of the 814 patients who met our criteria, 19 patients (2.3%, 95% confidence interval [CI], 0%-31.9%) were found to have objectively confirmed VTE, but none of the patients were symptomatic. Of the 411 patients in the LMWH group, 2 developed VTEs preoperatively and 4 postoperatively; of the 403 patients in the placebo group, 5 developed VTEs preoperatively and 8 postoperatively. The overall incidence of asymptomatic postoperative deep vein thrombosis (DVT) was 0.98% (95% CI 0%-20.3%) in the LMWH group and 2.01% (95% CI 0%-29.5%) in the placebo group without significant difference. Advanced age (odds ratio [OR] 1.050, 95% CI 1.014-1.088, P = .007) and high body mass index (OR 1.201, 95% CI 1.034-1.395, P = .016) were identified as risk factors in predicting occurrence of DVT. No fatal pulmonary emboli or major bleeding complication occurred in either group. CONCLUSION Routine anticoagulant prophylaxis was not found to be necessary for patients with foot and ankle fractures, although further investigation with a properly powered study design is required to definitively determine which foot and ankle patients are best served by anticoagulation and which ones are not. LEVEL OF EVIDENCE Level II, prospective comparative study.

Abstract
BACKGROUND There is a recognised link between lower limb cast immobilisation and the development of venous thromboembolism (VTE). Our aim was to assess the diagnostic accuracy of risk assessment models (RAMs) applicable to this patient group. This has not been done before. METHODS A literature and guideline review identified five RAMs. They were used to retrospectively risk assess a consecutive series of patients who were diagnosed with symptomatic VTE following lower limb injury treated with a cast (Group I). A case-matched cohort who did not suffer symptomatic VTE (Group II) was also retrospectively risk assessed. The RAMs' diagnostic performance indicators were calculated. RESULTS Groups I and II consisted of 21 patients each. There was no significant difference in the mean age or total number of VTE risk factors between Groups I and II (p=.957 and p=.878 respectively). The Plymouth (2010) RAM achieved the highest accuracy (54.8%). CONCLUSIONS Each RAM demonstrated significant limitations. Two displayed very limited clinical utility. Three recommended chemical thromboprophylaxis to all patients because they weighted lower limb immobilisation as an absolute risk factor for the development of VTE. Cast immobilisation should not be considered an absolute risk factor when risk assessing patients who all have casts. Prospective evaluation with a larger patient cohort is required.

Abstract
Huntington's disease is an autosomal inherited monogenetic condition in which the mutation is an expansion of the cytosine-adenine-guanine (CAG) repeat sequence at the N-terminal end of the huntingtin gene [1]. More than 40 repeats are associated with neuronal dysfunction and death, predominantly within the striatum resulting in a triad of movement, behaviour and cognitive impairment; other symptoms include weight loss, sleep disturbance and respiratory dysfunction, which may or may not be of primary neurological origin [1–3]. Death occurs 15–30 years after onset of symptoms [1], usually due to pneumonia [4], yet it is not known whether respiratory dysfunction is a feature of late stage disease or whether it appears earlier in the disease evolution. Previous research suggests that dysregulation within the respiratory centre results in irregular breathing patterns [5, 6]; decreased respiratory muscle strength and lung volumes have also been identified [7] which, alongside swallow dysfunction [4], could precipitate respiratory failure. Huntington's disease is a complex long-term condition and contributing factors such as swallow dysfunction, posture, physical inactivity and reduced exercise capacity have not yet been investigated in relation to respiratory function. We conducted a cross-sectional study aiming to characterise respiratory function across all stages of disease and explore primary and secondary contributors to respiratory decline. Given one previous report of respiratory weakness in Huntington's disease, we performed a follow-on study to assess the feasibility of home-based inspiratory muscle training in Huntington's disease. Respiratory function in Huntington's disease should be monitored from middle stage to preclude respiratory failurehttp://ow.ly/YXTt300mIQw

Abstract
OBJECTIVE To determine the mortality rate following total ankle replacement (TAR) and incidence of 90 day pulmonary embolism (PE) along with the associated risk factors. DESIGN Data-linkage study of the UK National Joint Registry (NJR) data and Hospital Episodes Statistics (HES) database. Linkage was performed in a deterministic fashion. HES episodes 90 days after the index procedure were analysed for PE. Mortality data were obtained pertaining to all the index procedures from the NJR for analysis. PARTICIPANTS All primary and revision ankle replacement patients captured on the NJR between February 2008 and February 2013. RESULTS The 90-day mortality following TAR was 0.13% (95% CI 0.03 to 0.52) and 1-year mortality was 0.72% (95% CI 0.40 to 1.30); no deaths were as a result of PE. The incidence of PE within 90 days following primary TAR was 0.51% (95% CI 0.23 to 1.13). There was only one PE following revision surgery. Patients with an Royal College of Surgeons Charlson score greater than zero were at 13 times greater risk of PE (p=0.003). CONCLUSIONS There is low incidence of PE following TAR, but multiple comorbidities are a leading risk factor for its occurrence.

Abstract
Current practice and controversies in UK bunion surgery are discussed. Patients tend to be offered a distally based metatarsal osteotomy, such as a chevron or scarf osteotomy, for mild to moderate symptomatic bunions. Greater deformities are managed with a more extreme scarf, supplemented with a proximal phalangeal osteotomy. A proximal fusion in the form of the Lapidus-type procedure is still reserved for the most severe, hypermobile, or arthritic cases. Minimally invasive techniques for bunions have failed to disseminate into common UK practice. The trends in the United Kingdom regarding litigation, venous thromboembolism, and osteodesis for bunion surgery are also discussed.

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
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. LEVEL OF EVIDENCE Level IV, case series.
