The use of an Esmarch bandage as a tourniquet in surgery has been criticized. Many authors claim that the pressures under the Esmarch are inconsistent and may be extremely high. We have seen few, if any, problems from the use of an Esmarch in surgery of the foot and ankle. The purpose of this study was to evaluate the pressures generated under the Esmarch tourniquet in a situation that mimics its clinical application, and to determine whether pressures of appropriate magnitude and consistency are obtained in order to recommend its continued use in surgery. Ten volunteers performed numerous applications of the Esmarch. The number of wraps and the width of the Esmarch bandage used were varied. The Esmarch was applied as it would be for a surgical case. Pressures directly beneath the Esmarch were recorded 8 cm proximal to the distal tip of the medial malleolus. Considering all volunteers and all pressures generated, a 3-in Esmarch applied with three wraps gave a mean pressure (±SD) of 225 ± 46 mm Hg. A 3-in Esmarch applied with four wraps gave a mean pressure of 291 ± 53 mm Hg. A 4-in Esmarch applied with three wraps gave a mean pressure of 233 ± 35 mm Hg, and a 4-in Esmarch with four wraps gave a mean pressure of 284 ± 42 mm Hg. The maximum pressures generated by any individual were as follows: 3-in three wraps, 321 mm Hg; 3-in four wraps, 413 mm Hg; 4-in three wraps, 328 mm Hg; and 4-in four wraps, 380 mm Hg. There was no significant difference in the magnitude or consistency of pressures generated between the experienced and inexperienced wrappers. There did not appear to be a learning curve for the application of the Esmarch bandage. We conclude that an Esmarch bandage, used as a tourniquet, can generate safe and reliable pressures. Either a 3-in or 4-in Esmarch bandage applied above the ankle with three circumferential overlapping wraps consistently results in pressures that are in a safe range.

Pressure Changes

Background: The goal of this study was to identify pressure changes throughout the peroneal groove after a groove deepening procedure. We hypothesized that pressures would decrease. Methods: Twelve fresh-frozen foot and ankle specimens were used. A thin pressure strip containing four sensor pads was secured within the peroneal groove with pads 1 through 4 positioned at the calcaneofibular ligament (CFL) and at the distal, middle, and proximal groove, respectively. The midstance phase of gait was simulated with loads applied to the plantar foot and posterior tibial tendon and to the peroneus longus and brevis tendons. Pressures were recorded with the ankle in neutral, plantarflexion, dorsiflexion, inversion, and eversion. Groove deepening was done by osteotomizing the posterior fibular wall. Pressure readings were then recorded. Average pressures for each of the four sensor pads after the procedure were compared to those obtained before the procedure. Results: The mean pressure overlying the CFL increased at all five ankle positions; however, these changes were not significant. Significant decreases in pressure were noted within the distal and middle groove at all ankle positions after the peroneal groove deepening procedure. Pressure within the proximal groove increased at all but one position, with a significant difference noted in neutral and plantarflexion. Conclusion: Pressures within the middle and distal peroneal groove significantly decreased after a groove deepening procedure. Combining this technique with peroneal tendon debridement may be advantageous for treatment of partial peroneal tendon tears or recalcitrant peroneal tendinitis.

Objective Osteochondral lesions of the talus are common injuries, with one of the leading treatment options being the M-BMS (matrix-augmented bone marrow stimulation) + I/III collagen scaffold. Osteotomy of the medial malleolus is not unusual but presents the risk of malunion or irritation by hardware. The aim of the study was to analyze data from the German Cartilage Society (Knorpelregister DGOU) to evaluate the influence of medial malleolar osteotomy on clinical results of M-BMS + I/III collagen scaffold. Design The ankle module of the Cartilage Register includes a total of 718 patients, while 45 patients met the inclusion criteria. Patients were treated with an M-BMS + I/III collagen scaffold of the medial talus, 30 without and 15 with an osteotomy of the medial malleolus. The follow-up evaluations included FAAM (Foot and Ankle Ability Measure), FAOS (Foot and Ankle Outcome Score), and VAS (visual analogue scale). Results Forty-five patients (22 male, 23 female) aged between 18 and 69 years (mean: 34 years) were included in this study. Between preoperative and 12 months postoperative, we noted a significant improvement in FAAM-ADL (Activity of Daily Living) ( P = 0.004) as well as FAOS-Pain ( P = 0.001), FAOS-Stiffness ( P = 0.047), FAOS-ADL ( P = 0.002), FAOS-Sport ( P = 0.001), and FAOS Quality of Life ( P = 0.009). There was no significant difference between patients who underwent an osteotomy or not. Conclusion The results show a significant improvement in patients’ outcome scores following a M-BMS + I/III collagen scaffold. No statistical difference was noted among those undergoing medial malleolar osteotomy.

Background: Syndesmosis is an important soft tissue component supporting the ankle stability and commonly injured accompanying with ankle fractures. The accurate reduction and fixation of syndesmosis is essential to obtain better functional results. Therefore, we aimed to find a practical method using the mortise view of ankle to determine the optimal syndesmosis fixation angle intraoperatively. Methods: We randomly selected 200 adults (100 women and 100 men) between 18 - 60 years of age. Three-dimensional anatomical models of tibia and fibula were created using Materialise MIMICS 21. We created a best fit plane on articular surface of medial malleolus and a ninety degrees vertical plane to medial malleolus plane. We determined two splines on cortical borders of tibia and fibula distant from the most superior point of ankle joint in horizontal view. We created two spheres that fit to the predefined splines. The optimal syndesmosis fixation angle was determined measuring the angle between the line connecting the center points of spheres, and the ninety degrees vertical plane to medial malleolus plane. Results: We observed no statistically significant difference between gender groups in terms of optimal syndesmosis fixation angles. The mean age of our study population was 47.1 {plus minus} 10.5. The optimal syndesmosis fixation angle according to mortise view was found as 21 {plus minus} 4.3 degrees. Conclusions: We determined the optimal syndesmosis fixation angle as 21 {plus minus} 4.3 degrees in accordance with the mortise view of ankle. The surgeon could evaluate the whole articular surface of ankle joint with the medial and lateral syndesmotic space in mortise view accurately and at the same position syndesmosis fixation could be performed at 21 {plus minus} 4.3 degrees.

The use of renal biopsy through laparoscopy is increasingly present both in human and veterinary medicine. However, both techniques require skill and training to make the operator capable to do it. The learning curve allows the quantitative and qualitative assessment of the number of attempts and minimum time for the surgical procedure. The objective included establish the learning curve for laparoscopy-guided kidney biopsy procedures in dog and pig corpses. Six dogs and six pigs corpses weighing less than 10 kg were used for this study. All corpses underwent kidney biopsy performed through laparoscopy. Twenty-four operators, two per animal, performed 20 renal biopsies each (10 for each kidney), with 480 collection-procedures in total. Duration and difficulty of the procedure and the biopsy sample quality were evaluated and statistical analysis was performed using a mixed regression model with a random effect of individuals and multivariate analysis of data. There were 91.5% of the samples that were adequate for evaluation. There was no significant difference in the number of glomeruli or cortex percentage considering the attempts in either species, demonstrating the operator’s ability since first collection. Swine samples showed higher amounts of renal cortex than canine samples. The procedure duration was shorter as more attempts were performed in dogs and pigs. From the fourth repetition, the professional reached a plateau for the variable related to ‘collection’, and from the second, the professional presented uniform duration for ‘sample storage’. Operators of the swine model acquired more agility than the dog ones. The variable ‘difficulty’ decreased as more repetitions were performed, reaching a plateau in the sixth attempt. Seven renal biopsies laparoscopy-guided are required for an operator to be considered ‘capable’ to perform the procedure in the referred species included. The learning curve for image-guided kidney biopsy procedures improves the implementation of this technique and benefits patients that undergo this procedure.

Abstract Aim The preperitoneal mesh position for inguinal hernia repair showed beneficial results regarding Chronic Postoperative Inguinal Pain (CPIP) with low recurrence rates. Two open preperitoneal techniques, the TransREctus Sheath PrePeritoneal (TREPP) and the TransInguinal PrePeritoneal (TIPP) technique, were compared in a randomized clinical trial with the hypothesis of less patients with CPIP after TREPP due to complete avoidance of nerve contact. Materials and Methods Adult patients with a primary unilateral inguinal hernia were randomized to either TREPP or TIPP in four hospitals. Prior to the trial’s start the study protocol was ethically approved and published. Outcomes included CPIP after 1 year (primary outcome) and recurrence rates, adverse events and Health related Quality of Life (secondary outcomes). Follow-up was performed at 2 weeks, 6 months and 1 year. Results Baseline characteristics were comparable in both groups. Pain was less often present after TREPP at 2 weeks and 6 months, but the CPIP at rest at 1 year was comparable 1.9% after TREPP vs 1.4% after TIPP, p = 0.535). The overall recurrence rate was higher in the TREPP group, 8.9% vs 4.6%, p = 0.022). Corrected for a learning curve for TREPP, no significant difference could be assessed (TREPP 5.7% and TIPP 4.8%, p = 0.591). Conclusions both the TREPP and TIPP technique resulted in a low incidence of CPIP after 1 year follow-up. The TREPP method can be considered a solid method for inguinal hernia repair if expertise is present. The learning curve of the TREPP techniques needs further evaluation.

Introduction: Posterior tibial tendon dysfunction is one of the most common, problems of the foot and ankle. Tenosynovitis of the posterior tibial tendon (PTT) is an often unrecognized form of PTT dysfunction. Case: A 54-year-old woman presented with left ankle pain that began while morning walk three days prior. She noted that the left ankle hurt with even light touch and the pain was unrelieved with sodium diclofenac. She denied any history of trauma. She was seen in the outpatient clinic for this condition. On examination, a three centimeter area of pain was found posterior to the medial malleolus and parallel to the PTT. She also had a stage I flat foot and mild soft tissue swelling around medial malleolus region on her radiograph examination. Ultrasound examination was done with the result of anechoic fluid visible in the peritendinous space around the PTT. The patient received diagnosis of PTT tenosynovitis, with the foot and ankle disability index (FADI) score was 58.7. Platelet rich plasma (PRP) injection was done twice with an interlude of two weeks. The pain subsided and the following FADI score was 84.6. Outcome: Patient showed improvement in her left ankle PTT tenosynovitis after two PRP injection. Conclusion: This case report highlights the efficacy of PRP as a modality in managing PTT tenosynovitis.

Background This study was performed to determine the factors that influence the clinical outcomes of surgically treated ankle fractures associated with the posterior malleolus (PM). Methods We evaluated 42 fractures of 42 patients. Posterior malleolus fracture size was calculated using computed tomography. Posterior malleolar fractures with a size less than 10% were left nonfixated. The decision for larger fragments was performed using fluoroscopy following the fixation of other components. If the joint was found to be congruent, the PM was left nonfixated. Otherwise, the PM was reduced and fixated. Clinical outcomes were evaluated based on Weber, Freiburg, and American Orthopaedic Foot and Ankle Society scores. Ankle osteoarthritis was determined according to the Canadian Orthopaedic Foot and Ankle Society classification. The effect of PM fixation, age, PM fragment size, waiting period before surgery, presence of ankle dislocation, and number of injured malleoli on clinical outcomes were assessed. Statistical significance was set at a value of P < .05. Results The mean patients age was 48.5 ± 14.9 years (range, 20–84 years) and the mean follow-up was 23.7 ± 8.6 months (range, 12–56 months). Fixation of the PM was performed solely in 12 patients. Postoperative displacement of the PM and articular step were less than 2 mm in all fractures. Statistically significant worse outcomes were demonstrated based on functional scores in the patients with a PM size greater than or equal to 25% (P = .042, P = .038, and P = .048, respectively) and in patients aged 60 years or older (P = .005, P = .007, and P = .018, respectively). However, there was no significant difference between functional scores and the other factors. Ankle osteoarthritis was observed at a higher rate in patients with PM size greater than or equal to 25% and in patients aged 60 years or older. Conclusions Clinical outcomes of the patients are mainly influenced by the patient's age and PM fragment size. However, if the tibiotalar joint is congruent, comparable results can be obtained in PM fixated or nonfixated patients.

Introduction: Proficiency in the direct anterior approach (DAA) as with many surgical techniques is considered to be challenging. Added to this is the controversy of the benefits of DAA compared to other total hip arthroplasty (THA) approaches. Our study aims to assess the influence of experience on learning curve and clinical results when transitioning from THA via posterior approach in a lateral position to DAA in a supine position. Methods: A consecutive retrospective series of 525 total hip arthroplasty of one senior and six junior surgeons was retrospectively analysed from May 2013 to December 2017. Clinical results were analysed and compared between the two groups and represented as a learning curve. Mean follow up was 36.2 months ± 11.8. Results: This study found a significant difference in complications between the senior and junior surgeons for operating time, infection rate, and lateral femoral cutaneous nerve (LFCN) neuropraxia. A trainee’s learning curve was an average of 10 DAA procedures before matching the senior surgeon. Of note, the early complications correlated with intraoperative fractures increased with experience in both groups. Operating time for the senior equalised after 70 cases. Dislocation rate and limb length discrepancy were excellent and did not show a learning curve between the two groups. Conclusion: DAA is a safe approach to implant a THA. There is a learning curve and initial supervision is recommended for both seniors and trainees. Level of evidence: Retrospective, consecutive case series; level IV.

AbstractAlthough prophylaxis for venous thromboembolism (VTE) is recommended after many surgeries, evidence base for use of VTE prophylaxis after foot or ankle surgery has been elusive, leading into varying guidelines recommendations and notable practice variations. We conducted a systematic review of the literature to determine if use of VTE prophylaxis decreased the frequency of subsequent VTE, including deep vein thrombosis (DVT) or pulmonary embolism (PE), compared with control. We searched PubMed, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov through May 2018, for randomized controlled trials (RCTs) or prospective controlled observational studies of VTE prophylaxis in patients undergoing foot and ankle surgery. Our search retrieved 263 studies, of which 6 were finally included comprising 1,600 patients. Patients receiving VTE prophylaxis had lower risk for subsequent DVT (risk ratio [RR]: 0.72; 95% confidence interval [CI]: 0.55–0.94) and subsequent VTE (RR: 0.72; 95% CI: 0.55–0.94). There was only one case of nonfatal PE, no cases of fatal PE, and no change in all-cause mortality (RR: 3.51; 95% CI: 0.14–84.84). There was no significant difference in the risk for bleeding (RR: 2.12; 95% CI: 0.53–8.56). Very few RCTs exist regarding the efficacy and safety of VTE prophylaxis in foot and ankle surgery. Prophylaxis appears to reduce the risk of subsequent VTE, but the event rates are low and symptomatic events are rare. Future studies should determine the subgroups of patients undergoing foot or ankle surgery in whom prophylaxis may be most useful.

Category: Ankle, Ankle Arthritis, Hindfoot, Midfoot/Forefoot Introduction/Purpose: Degenerative conditions of the ankle, hindfoot, and midfoot can markedly limit mobility. The Life-Space Assessment (LSA) is a questionnaire quantifying how patients mobilize after a medical event as they return to their previous daily settings. Current outcome measures do not accurately assess mobility in the geriatric foot and ankle population. In contrast, the effect of congestive heart failure (CHF) on patient mobility is routinely assessed via the New York Heart Association (NYHA) functional classification. The NYHA classification is stratified by limitation of physical activity: I (no limitation), II (some limitation), III (marked limitation), and IV (unable to carry out without discomfort). We hypothesized that degenerative conditions of the foot and ankle would be as mobility limiting as CHF. Methods: Patients over the age of 50 were included in this study. LSA data was prospectively collected from patients with degenerative ankle, hindfoot, and midfoot diagnoses at their preoperative visit and NYHA-classified CHF patients at a cardiology clinic. The degenerative foot and ankle cohort included Achilles tendonitis, ankle joint cartilage defects, ankle arthritis, subtalar arthritis, and midfoot arthritis. Patient demographics and comorbidities were recorded from the electronic medical record. Mean LSA data was analyzed and compared using a Student’s t-test. Results: 28 degenerative foot and ankle patients and 44 CHF patients met inclusion criteria for the study. Patient demographics, including age, gender, and BMI, were not significantly different between the two groups. The foot and ankle cohort had a mean LSA score of 68. Mobility of the foot and ankle group was significantly less compared to NYHA class I patients, who had a LSA score of 103 (p=0.008). There was no significant difference in mobility compared to class II or III congestive heart failure patients, who recorded a mean LSA score of 62 (p=0.60). There was insufficient data available on NYHA class IV patients to make comparisons to this group. Conclusion: Degenerative ankle, hindfoot, and midfoot pathology is associated with similar mobility limitation to that of NYHA class II and III congestive heart failure.
