Objective
To analyse whether early post-operative full weight bearing following syndesmotic ankle fixation affected radiographic outcomes suggestive of diastasis.Design
Retrospective comparative cohort study over a two year period.Setting
Level 1 trauma centrePatients/Participants
152 consecutive patients sustaining an unstable ankle fracture requiring syndesmotic stabilisation were included. Exclusions were 49 patients who had trimalleolar fixation without syndesmosis screws, one patient who had concomitant ankle and talar fracture. Five patients were lost to follow up and eleven patients were followed up in other centres. A total of 86 patients were analysedIntervention
Protected or full weight bearing.Main Outcome Measurement
The primary outcome measure was early diastasis. The secondary outcomes were late diastasis, wound complications and re-operation. Analysis of variance was used for the predictor variable of weight bearing status. We assumed a priori that p values of less than 0.05 were significant.Results
Median age was 36 (IQR 30), with 54 males and 32 females. Median follow up was 12 weeks (IQR 6). There was no significant difference when comparing weight bearing status and change in radiographic measurements intra-operatively compared to 6 and 12 week follow up radiographs (tibiofibular clear space p?=?0.799, tibiofibular overlap p?=?0.733 and medial clear space p?=?0.261).Conclusion
After surgical stabilization of an unstable syndesmotic injury, full weight bearing did not lead to syndesmotic diastasis in the early post-operative period. Full weight bearing is recommended following ankle fixation which includes syndesmotic fixation. 相似文献2.
Background
Few methods have been described for measuring hindfoot alignment from an anteroposterior view. The objective of this study was to compare two methods of angular measurement based on the views of Meary and Saltzman.Methods
Thirty asymptomatic volunteers were included. Four radiographs were performed: the views of Meary and Saltzman with parallel feet and with the Fick correction. The reproducibility was determined by the inter- and intraobserver variability (ICC).Results
Meary’s method revealed a mean valgus angulation of 3.9° (SD 3.47°). The reliability was extremely variable with a mean ICC of 0.59. The best reproducibility was obtained with Meary’s method with and without Fick correction.Conclusion
The results of this study show that the reliability of the angular measurements depends on the radiographic view and measurement method chosen. The lateral Fick correction did not counteract the influence of tibial rotation. The same method should be used consistently. 相似文献3.

Background
Current literature on carbon fiber implant use in foot and ankle surgery is scant. The purpose of this paper is to report medium-term outcomes of hindfoot fusion using a carbon fiber intramedullary nail.Methods
We retrospectively reviewed 30 cases of hindfoot fusion using carbon fiber intramedullary nail fixation between 2014 and 2017. We excluded revisions and cases with bulk allograft or ankle infection prior to surgery. We reviewed charts for length of followup, radiographic union, and complications.Results
Eleven patients were included (6 females, 5 males; mean age = 52 ± 15 years; mean BMI = 29.0 ± 6.4 kg/m2). Mean followup was 20 (range, 1.5–107) months. Nine of eleven cases achieved radiographic union while one case developed a complication requiring surgery. The mean time to union was 3 (range, 1.5–6) months.Conclusions
Carbon fiber implants offer several theoretical advantages over traditional metallic implants. They can be used safely in foot and ankle surgery without concern for high failure or complication rate. Larger scale studies with longer followup are needed on this topic. 相似文献4.

Objectives
Hip dislocations are highly morbid injuries necessitating prompt reduction and post-reduction assessment for fracture and incarcerated fragments. Recent literature has questioned the need for initial pelvic radiographs for acute trauma patients, resulting in computed tomography (CT) scans as the initial evaluation. This study investigates the relationship between choice of pre-reduction imaging and treatment of acute hip dislocations.Design
Retrospective Case-Control.Setting
Single Academic Level I Trauma Center.Methods
All acute hip dislocations from 2011 to 2016 were reviewed. Exclusion criteria were diagnosis of dislocation at another facility, death prior to reduction, emergent surgical or ICU intervention, and periprosthetic dislocation. Patients were grouped by those with only a radiograph prior to reduction, Group I, versus those with a pre-reduction CT scan, Group II. The primary outcomes were time to reduction and the acquisition of a second CT scan.Results
Of the 123 hip dislocations identified, 35 patients were excluded, mostly for transfer with a known dislocation. Group I included 29 patients and Group II included 59 patients. The mean time to reduction was 74?min in Group I and 129?min in Group II for a difference of 55?min (p?<?0.001). The rate of repeat CT scan was 0 in Group I versus 48 (81%) in Group II (p?<?0.001).Conclusion
Initial trauma pelvic radiography prior to CT is still important in the setting of suspected hip pathology to decrease time to hip reduction and unnecessary radiation exposure.Level of evidence

Background
Multiparametric magnetic resonance imaging (mpMRI) undoubtedly affects the diagnosis and treatment of localized prostate cancer (CaP). However, clinicians need a better understanding of its accuracy and limitations in detecting individual CaP foci to optimize management.Objective
To determine the per-lesion detection rate for CaP foci by mpMRI and identify predictors of tumor detection.Design, setting, and participants
We carried out a retrospective analysis of a prospectively managed database correlating lesion-specific results from mpMRI co-registered with whole-mount pathology (WMP) prostatectomy specimens from June 2010 to February 2018. Participants include 588 consecutive patients with biopsy-proven CaP undergoing 3-T mpMRI before radical prostatectomy at a single tertiary institution.Outcome measurements and statistical analysis
We measured mpMRI sensitivity in detecting individual CaP and clinically significant (any Gleason score ≥7) CaP foci and predictors of tumor detection using multivariate analysis.Results and limitations
The final analysis included 1213 pathologically confirmed tumor foci in 588 patients with primarily intermediate- (75%) or high-risk (12%) CaP. mpMRI detected 45% of all lesions (95% confidence interval [CI] 42–47%), including 65% of clinically significant lesions (95% CI 61–69%) and nearly 80% of high-grade tumors. Some 74% and 31% of missed solitary and multifocal tumors, respectively, were clinically significant. The majority of missed lesions were small (61.1% ≤1 cm); 28.3% were between 1 and 2 cm, and 10.4% were >2 cm. mpMRI missed at least one clinically significant focus in 34% of patients overall, and in 45% of men with multifocal lesions. On multivariate analysis, smaller, low-grade, multifocal, nonindex tumors with lower prostate-specific antigen density were more likely to be missed. Limitations include selection bias in a prostatectomy cohort, lack of specificity data, an imperfect co-registration process, and uncertain clinical significance for undetected lesions.Conclusions
mpMRI detects less than half of all and less than two-thirds of clinically significant CaP foci. The moderate per-lesion sensitivity and significant proportion of men with undetected tumor foci demonstrate the current limitations of mpMRI.Patient summary
Magnetic resonance imaging of the prostate before surgical removal for prostate cancer finds less than half of all individual prostate cancer tumors. Large, solitary, aggressive tumors are more likely to be visualized on imaging. 相似文献6.

Background
To compare the efficacy between fixation with suture-button and screw in the treatment of syndesmotic injuries: a meta-analysis.Methods
We comprehensively searched PubMed, Embase, and the Cochrane Library and performed a meta-analysis of randomized controlled trials (RCTs) and retrospective comparative studies (RTCs). We performed using Review Manager 5.2.Results
Three RCTs and six retrospective studies were conducted, including a total of 397 patients. The significant differences of the fixation of suture-button were reported for AOFAS scores (at 3, 6 and 12 months follow-up), full-weight time, reoperation, malreduction and the rate of failure of fixation. There were no significant differences between the groups regarding complications of infection, VAS, OMAS, range of motion, TFCS, TFO and MCS.Conclusions
Neither the functional outcome nor complications significantly differed between the fixation methods, but suture-button might lead to a quicker return to work. This analysis needs to be confirmed and updated by larger sample data and rigorously designed RCTs. 相似文献7.
Objective
Symptomatic distal interlocking screws in retrograde femoral nailing are common due the difficulties of imaging the trapezoidal femur. Screws appearing to have appropriate length on imaging may possibly be prominent, creating symptoms. Screw trajectory may influence the degree of this radiographic error. We hypothesize that external rotation of screw trajectory will increase measurement error of screw length.Design
Retrospective.Setting
Urban Level I Tertiary Trauma Center.Participants
283 patients with Computer Tomography (CT) scans of the native knee were retrospectively identified. Simulation was done of the trajectory of an interlock at 20?mm and 40?mm proximal to the nail entry point, which represent common screw positions associated/not associated respectively, with removal. The distance between the radiographic medial cortex and the tip of the transverse screw was calculated (D). The angle (Ψ) between the transverse trajectory and a modified trajectory aimed at the most medial cortex to avoid radiographic measurement error was calculated. Geometric modeling was utilized to calculate the measurement error (D) in the event of accidental external rotation. The angle of the medial slope was also measured (Θ).Intervention
Review of CT imaging of normal distal femora.Main Outcome Measurements
CT measurements of distal femora.Results
The mean distance (D) at 20/40?mm was 4.21 [95%CI 4.02–4.402] and 2.03?mm [95%CI 1.78–2.83], respectively (p?<?0.0001). The mean angle (Ψ) between the transverse and modified trajectory at 20/40?mm was 12° [95%CI 11.5–12.5] and 9.60° [95%CI 9–10.2], respectively (p?<?0.0001). External rotation by a similar amount nearly triples the measured difference (D). The measured medial slope was significantly increased as screws were placed more proximal (Θ20 mm 46.5 vs Θ40 mm: 48.7?°, p?<?0.00001).Conclusion
The distance between the perceived medial cortex and the tip of the most transverse screw is 4.21?mm and could account for painfully prominent screws. In more proximal screws this distance is decreased. Internal rotation of the screw trajectory 12° can reduce this distance (D), which has implications in nail design. External rotation, amplifies this difference nearly three-fold. Surgeons should avoid external rotation of the aiming arm to prevent prominent screws. 相似文献8.

Context
The European Association of Urology Renal Cell Carcinoma (RCC) Guideline Panel has prepared evidence-based guidelines and recommendations for the management of RCC.Objective
To provide an updated RCC guideline based on standardised methodology including systematic reviews, which is robust, transparent, reproducible, and reliable.Evidence acquisition
For the 2019 update, evidence synthesis was undertaken based on a comprehensive and structured literature assessment for new and relevant data. Where necessary, formal systematic reviews adhering to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were undertaken. Relevant databases (Medline, Cochrane Libraries, trial registries, conference proceedings) were searched until June 2018, including randomised controlled trials (RCTs) and retrospective or controlled studies with a comparator arm, systematic reviews, and meta-analyses. Where relevant, risk of bias (RoB) assessment, and qualitative and quantitative syntheses of the evidence were performed. The remaining sections of the document were updated following a structured literature assessment. Clinical practice recommendations were developed and issued based on the modified GRADE framework.Evidence synthesis
All chapters of the RCC guidelines were updated based on a structured literature assessment, for prioritised topics based on the availability of robust data. For RCTs, RoB was low across studies. For most non-RCTs, clinical and methodological heterogeneity prevented pooling of data. The majority of included studies were retrospective with matched or unmatched cohorts, based on single- or multi-institutional data or national registries. The exception was for the treatment of metastatic RCC, for which there were several large RCTs, resulting in recommendations based on higher levels of evidence.Conclusions
The 2019 RCC guidelines have been updated by the multidisciplinary panel using the highest methodological standards. These guidelines provide the most reliable contemporary evidence base for the management of RCC in 2019.Patient summary
The European Association of Urology Renal Cell Carcinoma Guideline Panel has thoroughly evaluated the available research data on kidney cancer to establish international standards for the care of kidney cancer patients. 相似文献9.

Background
Contrary to acute posterior cruciate ligament (PCL) bony tibial avulsions, surgical management of chronic injuries is technically challenging and appears to be controversial. We sought to assess the outcome of a novel screw post augmentation technique in neglected cases.Methods
16 patients were followed up in a tertiary single-center retrospective study. The bony fragment was fixed using a lag screw with a spiked washer and an additional screw post through an open posterior approach. The pre- and postoperative knee range of movement (ROM), laxity, and modified Tegner–Lysholm (TL) scores were compared.Results
The median time from injury to surgery was 10 weeks (range, 3–260). The mean clinical follow-up time was 24.25?±?9.21 months. At the final follow-up, the mean knee ROM flexion was 130°?±?11.55° with no extension lag. 3 patients had grade 1 laxity. The TL grade was predominantly excellent, and the overall median score improved from 76 preoperatively to 95 postoperatively (p?<?0.0004). Bony union was achieved in all cases.Conclusion
The described screw post fixation technique results in an excellent outcome for these rare injuries.Level of evidence

Introduction
In this retrospective study we have analyzed a consecutive series of patients affected by isolated radial head Mason III fractures and treated with bone resection or prosthesis.Patients and methods
This study includes 24 patients affected by fractures mentioned above and treated between July 2009 and November 2015.15 patients (average age 48 y.o.) have been treated with prosthesis. The remaining 9 (average age 573) have been treated with a capitellectomy instead.From a clinical point of view, we have evaluated the patients according to main performance indicators such as range of motion, pain, instability and Mayo Elbow Performance Score as parameters.Results
We have found similar results in both group, with an average MEPS value of 95 in the prosthesis group and 966 in the radial head resection group.The range of motion was similar too: between 1,3° and 1203° in the first group and between 4,4° and 120° in the second one. No significant complication has detected in any patient.Discussion
According to most recent literature, it is not precisely defined how to treat isolated Mason III fractures, contrary to what is defined in more complex pattern, in which prosthesis are now evaluated as the best indication.Due to radial head limited contribution to elbow stability, in absence of other bony or ligamentous lesions both capitellectomy and prosthesis can be good treatment in this kind of fracture.Conclusion
According to our experience and to the most recent literature, we recommend prosthesis in patient younger than 50 y.o., high demanding or manual worker, while in other cases we think that radial head resection can be the treatment of choice. 相似文献11.
Background
The main purpose of this study is to introduce our surgical technique and report surgical outcomes for percutaneous cable fixation in the treatment of subtrochanteric femoral fractures.Methods
Between May 2013 and April 2017, 51 patients with subtrochanteric femoral fractures treated with closed intramedullary nailing and percutaneous cable fixation were enrolled in this study. Postoperative angulation, union rate, time from injury to union, and femoral shortening were also evaluated to assess radiologic outcomes. Clinical outcomes, including range of hip flexion, walking ability, and Harris hip score at the last follow-up were evaluated.Results
Average coronal and sagittal angulation after surgery were 0.9 (range 0–5) and 0.3 (range 0–5), respectively. There was no postoperative angulation of more than 5°. Average shortening of the femur at 1-year follow-up was 2.7?mm (range 0–15). Bone union was achieved in 50 patients (98.0%) and average time to union was 18.6 weeks (range 12–48). Hip flexion, walking ability and Harris hip score at the last follow up were 115.6° (90–120), 7.9 (5–9), and 88.3 (65–100), respectively.Conclusion
Percutaneous cerclage cable fixation can provide a greater likelihood of achieving anatomical reduction and increased stability of fracture, while preserving biology around the fracture site. Thus, percutaneous cerclage cable fixation can be an effective surgical technique for the treatment of complex subtrochanteric fractures. 相似文献12.

Background
Although various minimally invasive procedures for chronic ankle instability are increasingly being used, a question regarding whether these procedures can be a viable alternative of the modified Broström procedure remains controversial. This study was conducted to compare the intermediate-term clinical outcomes between lateral ligaments augmentation using suture-tape and modified Broström repair in a selected cohort of patients.Methods
Sixty female patients with chronic lateral ankle instability were randomly assigned and underwent surgical treatments by one surgeon. Twenty-eight patients with suture-tape augmentation and 27 modified Broström procedures were followed ≥2 years and analysed in this comparative study. The clinical evaluation included the Foot and Ankle Outcome Score (FAOS), Foot and Ankle Ability Measure (FAAM), and stress radiographs. Medical expense related with operation was analysed to evaluate the cost-effectiveness.Results
There were no statistically significant differences in the clinical outcomes between two procedures based on FAOS, FAAM, recurrence rate of instability, and stress radiographs. Total medical expense was approximately 1.3 times more in the suture-tape group (P < 0.001), despite shorter operation time.Conclusions
Lateral ankle ligaments augmentation using suture-tape showed the similar clinical outcomes but low cost-effectiveness, as compared to modified Broström repair for young female patients with chronic ankle instability. 相似文献13.

Background
The aims of this study were to identify the artery feeding the fifth metatarsal and determine how bunionette osteotomy could injure this vessel.Methods
The nutrient artery entering the fifth metatarsal was investigated in 10 adult cadaveric lower limbs by barium injection and enhanced computed tomography.Results
The nutrient artery entered the medial aspect of the fifth metatarsal around the junction of the middle and proximal thirds obliquely from a distal direction (mean?angle 36°) in the coronal plane in all cases; in the axial plane, the point of entry and direction of the artery was medial-plantar (mean?angle 49°).Conclusions
This report revealed direction and location of the nutrient artery entering the fifth metatarsal. 相似文献14.

Purpose
The purpose of this study was to create an algorithm that simultaneously detects and characterizes (benign vs. malignant) focal liver lesion (FLL) using deep learning.Materials and methods
We trained our algorithm on a dataset proposed during a data challenge organized at the 2018 Journées Francophones de Radiologie. The dataset was composed of 367 two-dimensional ultrasound images from 367 individual livers, captured at various institutions. The algorithm was guided using an attention mechanism with annotations made by a radiologist. The algorithm was then tested on a new data set from 177 patients.Results
The models reached mean ROC-AUC scores of 0.935 for FLL detection and 0.916 for FLL characterization over three shuffled three-fold cross-validations performed with the training data. On the new dataset of 177 patients, our models reached a weighted mean ROC-AUC scores of 0.891 for seven different tasks.Conclusion
This study that uses a supervised-attention mechanism focused on FLL detection and characterization from liver ultrasound images. This method could prove to be highly relevant for medical imaging once validated on a larger independent cohort. 相似文献15.

Background and objectives
A prompt and effective management of trauma patient is necessary. The aim of this case report is to highlight the importance of intraoperative echocardiography as a useful tool in patients suffering from refractory hemodynamic instability no otherwise explained.Case report
A 41 year‐old woman suffered a car accident. At the emergency department, no abnormalities were found in ECG or chest X‐ray. Abdominal ultrasound revealed the presence of abdominal free liquid and the patient was submitted to urgent exploratory laparotomy. Nevertheless, she persisted suffering arterial hypotension and metabolic acidosis. Looking for the reason of her hemodynamic instability, intraoperative transthoracic echocardiography was performed, finding out the presence of pericardial effusion. Once the cardiac surgeon extracted pericardial clots, patient's situation improved clinically and analytically.Conclusion
Every anesthesiologist should be able to use the intraoperative echocardiography as an effective tool in order to establish the appropriate measures to promote the survival of patients suffering severe trauma. 相似文献16.
Aims
The anatomical safe zone for intra-medullary nail insertion through the tibial plateau is small, insertion outside of this area risks damage to intra-articular structures and poor fracture reduction. The purpose of this retrospective study was to determine if the new supra-patella (SP) approach confers improved nail insertion accuracy, when compared with the standard infra-patella (IP) technique.Patients and Methods
Two hundred cases were included in the study (SP 95, IP 105). Insertion accuracy was assessed on AP and lateral radiographic imaging, and measured as the distances between the central axis of the proximal nail and the ideal entry point.Results
The median distance from the ideal entry point was 4.4?mm (SP) and 5.1?mm (IP) (p?=?0.046) in the coronal plane, and 4.0?mm (SP) and 3.7?mm (IP) (p?=?0.527) in the sagittal plane. A narrower range in measurements was observed in the SP technique in both sagittal and coronal planes, 17.8?mm vs 28.6?mm, and 19.7?mm vs 30.3?mm respectively.Conclusion
We found that the SP technique achieved significantly improved nail insertion accuracy in the coronal plane. Insertion accuracy was equivocal between the two techniques in the sagittal plane. A narrower range in entry points was observed in the SP cohort in both planes suggesting improved control in nail insertion using this technique. 相似文献17.

Objective
The objective of this study is to broaden our understanding of psychiatric disorders due to work-related burn injury compensated by the Industrial Accident Compensation Insurance operated by the Korea Workers’ Compensation and Welfare Service (KCOMWEL).Methods
Using the KCOMWEL electronic database, we collected data on psychiatric disorders due to work-related burn injury based on workers’ compensation records from 2005 to 2014 and analyzed the characteristics of the claims.Results
The average number of claims per year for post-traumatic stress disorder was 67 and the approval rate from 2005 to 2014 was 53.6%. Regarding occupation, 63 workers were elementary workers involved in the performance of simple and routine tasks which may require the use of hand-held tools and considerable physical effort and 59 were electrical and electronic equipment fitters and repairers. Acute stress disorder, nonorganic insomnia, and sexual dysfunction were the most commonly approved psychiatric disorders associated with work-related burn injury, followed by mixed anxiety-depressive disorder.Conclusions
We analyzed the characteristics of the psychiatric disorders due to work-related burn injury for which compensation was received from 2005 to 2014 according to the approved results. To gain a long-term understanding of the management of workers’ compensation status for psychiatric disorders due to work-related burn injuries, we should gather accurate information on the risk factors involved in order to achieve the needed systematic improvements. 相似文献18.

Background
The number of screws used for sliding calcaneal osteotomy fixation has not been examined in the literature. The purpose of this paper is to examine this topic.Methods
Retrospective chart review was performed on 190 patients who met selection criteria. We compared complication risk for single versus double screw, headed versus headless screw, and short versus longitudinal incision cases.Results
The mean age was 48.4 (18–83) years and average follow up was 28 (12–150) weeks. All cases achieved radiographic union. Overall complication rate was 19.5% (37/190). Risk of complication did not differ significantly between single and double screw (RR: 1.170; 95% CI: 0.66–2.09; p = 0.594) or short and extended incision groups (RR: 0.868; 95% CI: 0.42–1.80; p = 0.704). Risk of complication differed significantly between headed and headless screw fixation (RR: 5.558; 95% CI: 2.69–11.50; p < 0.0001).Conclusions
Single screw fixation of sliding calcaneal osteotomy achieves similar outcomes as double screw fixation. Headless screws are advantageous for minimizing hardware pain and subsequent hardware removal. 相似文献20.
