Authors: Waldrop Norman , Cain Lyle , Emblom Benton , Ryan Michael 
Published: September 2017

Category: Sports Introduction/Purpose: Return to sport criteria after surgical treatment of lower extremity injuries are highly variable and without consensus. Thigh measurements assessing atrophy, single-leg hop testing and isokinetic strength measurements are commonly used metrics when considering return to sport after surgical treatment of lower-extremity injuries. Yet, these modalities are limited in scope, as they do not fully or accurately evaluate functional movements required in elite athletics. Alternatively, using new Global Positioning System (GPS) technology, a wide breadth of functional movements can be tracked for each athlete, which can be used as a comparative self-control in the event of an injury. This data proposes a more comprehensive, dynamic and longitudinal comparison of athlete performance, which may more accurately reflect functional return to sport in elite athletes after surgery. Methods: Over a three-year period, GPS data was collected on thirteen elite American College Football players at a single FBS Subdivision University. A total of 300 data points per athlete were collected for every practice, scrimmage and game starting in spring prep and extending through regular season, and post-season play. A total of 5.7 million data points including total distance traveled, average and maximum velocity, acceleration profiles, and explosive change of direction through inertial movement analysis were prospectively collected and analyzed. Individual pre-injury GPS functional profiles for each of the thirteen athletes were used as baseline, healthy comparisons, and functional recovery was determined prospectively during return to play progression after lower extremity surgery. Return to sport was allowed when post-operative GPS profiles demonstrated equivalence or superiority of all parameters compared to pre-injury measurements. Results: All thirteen players returned to sport after all measured parameters were equal to or greater than pre-injury levels. Conclusion: Modern GPS technology employed during preseason, regular season and post-season establishes an individualized, baseline, profile of lower-extremity function which allows for postoperative comparison and prospective assessment of safe return to play in elite football players.

Category: Ankle, Ankle Arthritis Introduction/Purpose: Total ankle arthroplasty (TAA) has become an increasingly attractive option for advanced tibiotalar arthritis treatment. The Salto prosthesis (Tornier SA, Saint Ismier, France) was reported to have midterm and long term promising outcomes. However, to date, the clinical reports of this prosthesis are few and most of the papers were published by the inventors and disclosed consultants. The published areas are also limited to Europe, and no results were documented from other region. Methods: We retrospectively reviewed 62 patients in total. All of underwent unilateral Salto TAA. The average clinical follow-up was 34.3 months. Clinical and radiologic results were evaluated and enrolled. Clinical follow-up included medical records review, visual analogue scale (VAS) pain score, American Orthopeadic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Ankle Osteoarthritis Scale (AOS) pain and disability score and range of motion (ROM). Apart from these, subsequent surgeries and perioperative events that occurred at the first 3 months after the operation were recorded simultaneously. In the radiographic evaluation, we measured the tibial angle (TA), talar angle (TAL), tibial slope, and talocalcaneal angle (TCA) described by Bonnin. Distributive regions of osteolysis and radiolucency were reviewed. In addition, heterotopic ossification also be observed and graded. Endpoint of the follow-up was either any component removal or reoperation for any reason. Results: Date to last follow-up, the survival rate with any reoperation as the endpoint was 88.7% (7/62). Using any component removal as the endpoint of followup, the survival rate was 95.2% (3/62). The mean VAS score, AOFAS ankle-hindfoot score, and AOS pain and disability score were improved postoperatively (p < 0.001). Postoperative ROM of ankle was also improved (p = 0.003). Within 6 weeks of postoperation, radiolucent line arose around tibial implant in 39 cases and disappeared at mean 5.5 ± 2.6 months. 28 patients with postoperative mean 8.5 ± 4.5 months appeared radiolucent area. Osteolysis was found in 28 patients with mean 18.1 ± 8.2 months postoperatively. 13 patients suffered heterotopic ossification which appeared 9.4 ± 4.3 months after operation. Conclusion: At the last followup, obvious pain relief and satisfactory results were achieved in most of the patients. Different from previous studies on Salto prosthesis, we considered that the early radiolucent line around the tibial implant is likely due to the tiny gap between the implant and bone contacted interface, and it would disappear at the time of osseous integration. The lucent area and osteolysis occurred frequently around the tibial keel and tray due to the stress shielding of the tibial component. However, longer follow-up is necessary to determine the durability of this implant.
Biomechanical study of screw fixation and plate fixation of a posterior malleolar fracture in a simulation of the normal gait cycle
Authors: Wang Xu 
Published: September 2017

Category: Ankle Introduction/Purpose: Fixation of the posterior malleolar fracture with plate or screws is under debating. A fatigue loading system and a spatial motion capture system will provide a theoretical basis for the selection. Methods: Thirty-six below-knee specimens with Haraguchi I type posterior malleolar fracture model was obtained. The specimens were randomly divided into two groups, Group A used two parallel-placed 3.5 mm semi-threaded hollow titanium alloy screws to fix the fracture from back to front; group B used an anatomical plate to fix the posterior malleolus. According to the ratio S of the area of the sagittal fracture over the total area of the distal tibial articular surface, each group was subdivided into three groups recorded as A1, B1; A2, B2; and A3, B3. In group A1 and B1, S=1/4; in A2 and B2, S=1/3; in A3 and B3, S=1/2. In the simulations of gait cycle, 4 kinds of ankle joints were subjected to mechanical loading. A fatigue loading system was used for repeated loading. The spatial motion capture system was used to measure the displacement X (mm) in the final stage of loading. Results: At different locations and different loading conditions, the posterior malleolar fracture displacement X in the three groups of posterior malleolar fracture showed no statistically significant difference. Conclusion: here is no biomechanical difference between the internal fixation of two parallel 3.5-mm hollow screws and anatomical plate for Haraguchi I type posterior malleolar fractures with an average fracture block height of 19.27 mm.

Authors: Wang Xu 
Published: September 2017

Category: Sports Introduction/Purpose: To evalute if the MRI Signals can be the predictor of osteochondral lesion of talus Methods: From Jul. 2012 to Oct. 2014, 3.0 T MRI scanning was performed in 20 cases of ankle sprain. MRI scanning was performed every 3 monthes and the followed-up time of each case was 12 months. The signal of cartilage, subchondral bone and marrow edema were recorded and analyzed comparatively. Results: The signal of marrow edema in talus body of 14 cases were decreased step by step and disappeared eventually. The time from injury to the marrow edema disappear was more than 9 months. 4 cases became III° osteochondral lesion and 2 cases have subchondral bone cyst formation. Conclusion: The reason of OLT and pain were under discussion. After sprain, what changes occured in the talus body and cartilage were under debate. How the subchondral bone cyst formation was unknown. Continuous MRI scanning may have some value in evaluation of the OLT. From the results of our study, we can see that the edema signal in most case can disappear in about 9 months. The OLT and cyst formation may resulted from violent force and no-standard conservative treatment. MRI scanning can help the surgeon decide when to perform operation and choice the operative procedure.

Category: Trauma Introduction/Purpose: This study aims to assess the detailed radiologic outcomes which used uninjured side weight-bearing radiograph as a template as well as clinical results to compare the Ollier approach with screw fixation and the extensile lateral approach with lateral plating. Methods: We performed a retrospective review of intra-articular calcaneal fractures treated operatively in our hospital from January 2009 to November 2014. Radiologic outcomes were assessed using radiologic parameters such as Böhler angle, calcaneal height, and talar sagittal angles represent calcaneal deformation by the comparison of the final follow-up bilateral weight-bearing lateral radiograph. Functional outcome was assessed through the American Orthopaedic Foot and Ankle Society (AOFAS) scores and Visual Analog Scale (VAS) pain scores. Postoperative complications were investigated. Results: Ninety-seven unilateral fractures were appeared to match our inclusion criteria: forty-six fractures were treated by using the extensile lateral approach with lateral plating (the ELP group), and fifty-one fractures were treated with the Ollier approach and screw fixation (the OS group). The operation time was significantly shorter in the OA group (p<0.05). There were no significant difference of the final follow-up radiologic parameters between two groups. The mean AOFAS scores were significantly higher in the OS group (p = 0.020) and both groups showed similarity in the VAS pain scores (p = 0.175). Overall soft-tissue complications were 28.3% in the ELP group and 9.8% in the OS group (p = 0.034). Conclusion: No difference could be shown in the postoperative and final follow-up radiological outcomes between the Ollier approach and the extensile lateral approach, but the Ollier approach had better functional score and lower soft tissue complication rate with shorter operative time.

Published: September 2017

Category: Basic Sciences/Biologics Introduction/Purpose: To investigate the effect of cuboid osteotomy lateral column lengthening (LCL) for the correction of stage? B adult-acquired flatfoot deformity in cadaver. Methods: Six cadaver specimens were compressively loaded to 350 N. Flatfoot models were established and each was evaluated radiographically and pedobarographically in the following conditions: (1) intact foot, (2) flatfoot, (3) cuboid osteotomy LCL (2, 3, 4, and 5 mm). Results: Compared with the flatfoot model, the 2-,3-,4-, and 5-mm LCLs showed significant correction of talonavicular coverage on anteroposterior radiographs and talus-first metatarsal angle on both anteroposterior and lateral radiographs. As the graft increased in size incrementally, lateral forefoot pressure increased consistently, and medial pressure decreased significantly except for the 2-mm LCL. Compared with the intact foot, the above angles of the LCLs showed no significant difference except for the 2- mm LCL. In terms of forefoot pressure, medial pressure of the 2-mm LCL and lateral pressure of the 3-, 4- and 5-mm LCLs showed statistical differences, but lateral pressure of the 3-mm LCL was not much more than the intact foot as compared to the 4- and 5-mm LCLs, which was still less than medial pressure. Conclusion: Cuboid osteotomy LCL procedure avoids damage to subtalar joint and has a good effect on correction of stage? B adult-acquired flatfoot deformity with a 3 mm lengthening in cadavers.

Category: Ankle, Arthroscopy, Hindfoot, Lesser Toes, Midfoot/Forefoot, Sports, Trauma Introduction/Purpose: The occurrence of venous thromboembolisms (VTE) in the management of foot and ankle conditions can lead to serious and sometimes fatal complications. The reported incidence range of symptomatic deep venous thrombosis (DVT) following various foot and ankle procedures is wide, ranging from 0.01% to 23.4%. The incidence of asymptomatic DVT is likely higher and has been reported to be up to 34% in patients with Achilles ruptures. In line with the wide variability in incidence data, there remains a lack of consensus in determining the necessity to implement DVT prophylaxis after foot and ankle surgery. The purpose of this study was to examine the National Surgical Quality Improvement Program (NSQIP) database to assess the 30- day risk of VTE in foot and ankle surgery. Methods: The ACS-NSQIP database for the years 2011-2014 was queried for patients undergoing elective versus non-elective foot and ankle surgery with a total of 72 Current Procedural Terminology (CPT) codes included. Those undergoing procedures for an infectious process or oncologic procedures were excluded. A total of 18,632 cases were included for analysis in our study with 11,744 being elective and 6,888 non-elective surgeries. A univariate analysis of thromboembolic parameters included in the database was conducted to measure the difference between the two cohorts. Results: There were a total of 6,888 non-elective (36.97%) and 11,744 elective surgeries (63.03%). The incidence of DVT was 32 (0.33%) for elective and 39 (0.46%) for non-elective surgery with no statistical significance (P=0.37). The incidence of pulmonary embolisms (PE) was 24 (0.35%) for the non-elective and 20 (0.17%) for the elective group with the non-elective group having a statistically significant increase (P = 0.0156). The incidence of cerebral vascular accidents (CVA) was 8 (0.06%) for males and 1 (0.009%) for females with males having a statistically significant higher incidence of CVA (P = 0.0318). Patients under age 65 had a statistically higher risk (P = 0.0194) of a CVA occurrence with an odds ratio of 0.132 times greater than those over the age of 65. Conclusion: Non-elective Foot & Ankle surgery is an independent risk factor for pulmonary embolism. Males under the age of 65 years old are more likely to experience CVAs with residual deficits. However, the overall incidence of PE and CVA are exceedingly low in our study with an incidence of under half a percent. The incidence of DVT was also low, under 0.5% for the non-elective group and 0.33% for the elective group. Therefore, surgeons should weigh the risks and benefits of anticoagulation, especially in elective foot and ankle surgery, prior to the initiation of anticoagulation therapy.

Category: Midfoot/Forefoot Introduction/Purpose: The purpose of this study was to evaluate the clinical outcomes using a double stemmed flexible silicone prosthesis for the treatment of Freiberg disease in its late stages. Methods: The subjects consisted of 13 feet from 13 cases suffering from Freiberg disease that underwent extra-articular dorsal closing-wedge osteotomy using a polyblend suture. The average age was 31.7 (range 13–72) years. The average follow up period was 17 (range 14–24) months. Regarding image findings, time to bone union and metatarsal shortening was reviewed. The investigation was carried out using the range of motion (ROM), visual analog scale (VAS), and Japanese Society of the Surgery of Foot lesser toe scale (JSSF score) in the MTP joint before surgery and at the latest follow-up. Results: Calluses under the metatarsal head were not observed in any cases. The mean metatarsal shortening was 2.33± 2.07 mm at follow-up. The bone union required an average of 8.4±0.8 weeks. The average ROM of dorsal flexion improved from 37.2±5.3° before surgery to 73.6±9.9° at latest follow-up (p<0.0001). The average ROM of plantar flexion improved from 16.0±10.1° before surgery to 19.5±8.6° at latest follow-up (p=0.35). The average VAS significantly improved from 75.3±8.5 before surgery to 4.9±4.2 at latest follow-up (p<0.0001). The average JSSF score significantly improved from 67.3±9.4 points before surgery to 98.8±3.0 points at the latest follow-up (p<0.0001). Conclusion: Extra-articular dorsal closing-wedge osteotomy using a polyblend suture was carried out to treat Freiberg disease. The bone union was observed in all cases with improved clinical results. Fixation using a polyblend suture was considered to be useful.

Hepatic veno-occlusive disease is defined as nonthrombotic fibrous obliterative endophlebitis of small centrilobular hepatic venules.Clinically, patients present with elevated liver enzymes and a triad of jaundice, hepatomegaly and ascites. Although reported as a complication of other solid organ and stem cell transplantation, there have been no reported cases to date of veno-occlusive disease following lung transplantation.The present authors report a case of veno-occlusive disease following single-lung transplantation in a patient on a triple-drug immunosuppressive regimen composed of tacrolimus, mycophenolate mofetil and prednisone.The diagnosis was established by transjugular liver biopsy and by discontinuing tacrolimus; there was clinical regression of symptoms and serological return to baseline.
Airway calibre variation is a major determinant of exhaled nitric oxide's ability to capture asthma control
Authors: Michils Alain , Haccuria Amaryllis , Michiels Sebastien , Van Muylem Alain 
Published: September 2017

Changes in airway calibre have the potential to modify exhaled nitric oxide fraction (FENO) values and could hamper howFENOcaptures changes in asthma control. Here, our objective was to assess whether forced expiratory volume in 1 s (FEV1) variations alter the ability ofFENOto reflect asthma control.FENO, asthma control (Asthma Control Questionnaire (ACQ)) and FEV1were measured at least two times in 527 patients during 1819 pairs of visits. Determinants ofFENO–ACQ discordance probability were evaluated through a logistic regression analysis. The effectiveness ofFENOat capturing either asthma control worsening or improvement between two visits was then assessed by undertaking a stratified receiver operating characteristic curves analysis.When FEV1andFENOchange in the same direction, the odds ofFENO–ACQ being discordant are multiplied by 3 (p<0.001). The area under the curve values were 0.765 (95% CI 0.713–0.805) (improvement; p<0.001) and 0.769 (95% 0.706–0.810) (worsening; p<0.001) or 0.590 (95% 0.531–0.653) (improvement; p=0.001) and 0.498 (95% 0.416–0.567) (worsening; p=0.482) when FEV1andFENOchanged in the opposite or same direction, respectively.The manner in whichFENOand FEV1vary concomitantly when asthma control changes determines the ability ofFENOto capture this change: parallel or opposite changes in FEV1andFENOeither decrease or increase this ability to capture asthma control changes.
SensDeploy: efficient sensor deployment strategy for real-time localization
Authors: Lee Jin-Hee , Shin Byeong-Seok 
Published: September 2017

AbstractIn order to estimate the location of the user, the previous studies introduced many sensor deployment methods applying the sensor network. The important issues to consider when placing the sensors are a configuration cost and detection area of a sensor network. In other words, the sensors consisting the network should be optimally deployed by taking into account the coverage and connectivity of them. In this paper, a sensor signal is modeled as the Gaussian distribution based signal points group, and signal points in overlapping region between two different sensors are classified by e-SVM (support vector machine) method as each sensor group. In addition, a trilateration technique is used for estimating the position of a moving object. At this time, we efficiently deploy the sensors with f-Apriori method to maintain the connectivity between the sensors as well as to apply the trilateration. The proposed method can be utilized for optimal placement of sensors if we know a detection range of one sensor. In this paper, we introduce more effective and adaptive deployment method to consist the sensor network as taking into account the cost and the situation.

Authors: Kavlak Tulay , Hisar Filiz 
Published: September 2017

Purpose:This study was carried out in order to determine the anxiety levels of menopausal women on their sexual satisfaction.Method and material:This descriptive study. The study was carried out at a menopause clinic of a state hospital between June and August 2011. Data were collected by questionnaire: the Golombok Rust Inventory of Sexual Satisfaction (GRISS) and the State Trait Anxiety Inventory. Results:The mean age of the participants was 49.2±7.6 years old and nearly half of the women 46-50 age group. Half of the women in our sample had a chronic disease, 46.4% of women had sexual intercourse twice a week and 85.1% of them were housewives. In our research it was found that the women’s sexual satisfaction was low, and their state anxiety levels were moderate level. There was a moderate positive correlation between the women’s sexual satisfaction scores and their anxiety levels. Increased levels of both state and trait anxiety in women reduces their sexual satisfaction. Conclusion:In this study, it was shown that women’s anxiety levels were middle and their sexual satisfactions were decreased during menopause. For this reason menopausal women’s should recommended give information about sexual and psychological consultancy services.

Abstract
This paper investigates an application of ultrasonic stirring in water and oil-immersion quenching of a medium carbon steel sample. By developing a pressure acoustic simulation, the distribution of ultrasound pressure and acceleration in quenching media was predicted. By using the standard temperature probe of Inconel 600, the cooling curves of water and quench oil were recorded with and without ultrasound agitation. Using the same conditions, a quenching of the steel cylinders made for carbon steel C45 was performed. The experimental results have shown a significant impact of ultrasound agitation on cooling curve parameters, sample distortions, and surface hardness distribution and its hardenability.
