Published: February 2018

The suppressive biological control of mites on oilseeds can be successful under the circumstances of the ratio of prey and predators being I : 20 to 1 : 50 and the original infestation not being higher than 500 specimens per 1 kg. Preventive biological control was carried out in empty oilseed stores after they were cleared. The predators which were released in the stores 2000 specimen s being evenly distributed over an area of 100 m<sup>2</sup> were successful and suppress the population of acaroid mites.
La perversidad de las tasas judiciales en el sistema constitucional
Authors: Couso Fernández-Getino Jorge 
Published: February 2018

Las tasas judiciales han constituido una figura tributaria que ha contado con el rechazo de todos los operadores jurídicos por su carácter limitador del derecho fundamental a la tutela judicial efectiva. El Tribunal Constitucional ha aplicado parches jurisprudenciales sobre este tributo suprimiendo paulatinamente gran parte del gravamen para solventar las graves deficiencias constitucionales y tributarias del legislador en su regulación. Su justificación constitucional encontraba en la justicia gratuita su respaldo legislativo pero se ha demostrado que no se ha satisfecho este fin legítimo que exige la jurisprudencia. En cualquier caso, un tributo que además del intrínseco carácter tributario es dotado de efectos procesales estaba condenado a su eliminación, como así ha sido, pese al insuficiente y paulatino proceso de adaptación constitucional

Purpose
Despite various techniques used in atrial fibrillation ablation, recurrence of atrial arrhythmias still constitutes a clinical problem. The aim of this study was to document the long-term outcomes of pulmonary vein isolation with a ring-shaped ablation catheter (PVAC).

Methods
All consecutive patients presenting with paroxysmal or persistent atrial fibrillation (pxAF or perAF, respectively) treated with PVAC (first generation) were enrolled. After standard follow-up during the first year, all patients were contacted for long-term follow-up. In addition to the patient's medical history, 3-day Holter monitoring was performed. Endpoints were atrial fibrillation-related symptoms, ECG documentation of atrial fibrillation or other left atrial arrhythmias and reablation.

Results
In total, 125 patients (78% with pxAF) were enrolled. All but two pulmonary veins (0.4% of 485 pulmonary veins) could be successfully isolated. At 12 months, 83% of patients in the pxAF group and 53% of patients in the perAF group were free from symptoms. The mean long-term follow-up was 51 ± 14 months. Regarding long-term efficacy, 56% of patients in the pxAF group and 28% of patients in the perAF group were free from any recurrence at 72 months. Independent predictors of event-free survival were perAF (hazard ratio 2.76, P = 0.001) and the existence of mild valvular disease (hazard ratio 2.69, P = 0.001). No significant complication due to PVAC occurred, especially no ischemic stroke.

Conclusion
Long-term follow-up indicated for the first time in such a considerable cohort that pulmonary vein isolation with PVAC is a safe and very efficient method for treating pxAF – despite known microembolism issues. Patients with perAF receive less benefit from PVAC and ablation therapy should be reserved to pxAF. Significantly, even mild valvular disease was an independent predictor of atrial fibrillation recurrence.

Robot-assisted upper cervical spinal surgery
Authors: Tian Wei , Fan Mingxing , Liu Yajun 
Published: February 2018

The fundamental for upper cervical spinal surgery is screws fixation progress, however, anatomical variations of atlantoaxial vertebrae are wide, and the region is adjacent to important organ such as spine cords, oblongata and vertebral artery, all of which make the fixation harder. Robot-assisted navigation can make up for the above shortcomings, and has the potential to more improve the screw placement accuracy.We recently designed a robot system called TiRobot, which is based on intraoperative three-dimensional images. TiRobot has three components: the planning and navigation system, optical tracking system and robotic arm system. By combining navigation and robot techniques, TiRobot can guide the screw trajectories for orthopedic surgeries.TiRobot has been used in upper cervical surgeries with the approval from the Ethics Committee. There were 7 screws inserted during the surgeries, 1 screw for posterior C1- 2 trans-articular fixation, 1 screw for anterior odontoid fixation and 5 for C1 or C2 pedicel fixation. All surgeries were smoothly performed using TiRobot. According to the post-operation CT image data, all the screw placements were sufficient because there was no perforation of the spinal canal or any unexpected malposition. According to the Gertzbein-Robbins classification, all screws fell into group A. Furthermore, there was a discrepancy between the planned and the actual placements at the entry points and the end points. The average deviation in entry point and end point were 1.21 +/- 0.45mm and 1.19 +/- 0.36mm. These safe and accurate results make TiRobot the first medical robot could be used in upper cervical spinal surgery.

Published: February 2018

Total knee arthroplasty using navigation system is known to be more effective than conventional methods in achieving more accurate bone resection and neutral alignment.1 Mobile bearing is also known to reduce wear and automatically correct rotational malalignment of the tibia but the long-term follow-up results of more than 10 years are extremely rare.2, 3 The purpose of this study is to investigate the results of clinical and radiologic long-term follow-up and complications of total knee arthroplasty using navigation and multi-directional mobile bearing.From 2003 to 2006, a total of 111 navigation TKAs using multi-directional mobile bearing design were carried out and reviewed retrospectively. TKAs were performed by two experienced surgeons at one institute. Of the 111 patients, 102 were women and 9 were men. The mean duration of follow-up was 11.4 ± 1.0 years (range, 10.1 to 14.08 years). Clinical outcomes were evaluated in terms of Knee Society Score, Hospital for Special Surgery score, Western Ontario and McMaster University (WOMAC) score, range of motion and complications. Long-term radiological outcomes and survival rates were evaluated at least 10 years.Average preoperative HSS score was 66.5 ± 9.8 and KSS pain and function score were 25.0 ± 11.8 and 44.5 ± 12.3, respectively. Scores improved to 94.1 ± 8.2, 46.6 ± 11.6 and 88.2 ± 14.6 at the last follow up, respectively. Mean preoperative WOMAC scores of 75.8 ± 16.5 improved to 13.8 ± 16.0 at last follow-up. Five knees required re-operation, two for liner breakage, one for liner wear, one for distal femoral fracture and one for infection. The estimated 10-year prosthesis survival rates for any reason and for prosthesis-related problems were 95.5% and 97.4% , respectively.TKAs using each techniques resulted in similar good clinical outcomes and postoperative leg alignments. Robotic and navigation TKA appeared to reduce the number of postoperative leg alignment outliers and revision rate compared to conventional TKA.

Published: February 2018

The purpose of this study is to evaluate the effect of postoperative mechanical alignment on clinical outcomes and revision rate by comparing acceptable mechanical axis group from neutral and an outlier mechanical axis.Between 2000 and 2006, clinical and radiographic data of 334 primary TKAs were retrospectively reviewed. Post-operative mechanical axis was investigated within 1 month after TKA. The first group was an acceptable group of 286 knees (85.6%, with mechanical axis of 0°±3°). The second group was an outlier group of 48 knees (14.4%, with mechanical axis of beyond 0°±3°). Clinical outcomes before surgery and at the final follow up were analyzed using scoring method such as Hospital for Special Surgery, Knee Society Score, and Western Ontario &amp; McMaster Universities Osteoarthritis Index (WOMAC) score. Radiologic outcomes including changes of mechanical axis between immediate postop and last follow-up were evaluated. Postoperative complications and revision rates were also evaluated.The mean degrees in change of mechanical axis between immediate postop and last follow-up were greater in the outlier group (1.6°±2.7) than acceptable group (0.8°±2.4). No significance difference in clinical outcome was found between the two groups. The incidence of aseptic loosening, instability, polyethylene wear, polyethylene breakage, and periprosthetic fracture was 2/4/2/2/2 each in the acceptable group and 1/1/2/0/0 each in the outlier group. Six (2.1%) of 286 in the acceptable group and 4 (8.3%) of 48 in the outlier group were revised (p=0.04). The Kaplan-Meier survival analysis showed a tendency towards improved survival with restoration of neutral mechanical axis. However, such improvement was not statistically significant (p=0.25).Restoration of neutral limb alignment is a factor of total knee arthroplasty that can result in less revision rate and higher longevity. However, there are no significant differences in clinical outcomes between the two groups.
Trackerless 3D Ultrasound Stitching for Computer-Assisted Orthopaedic Surgery and Pelvic Fractures
Authors: Pandey Prashant , Abugharbieh Rafeef , Hodgson Antony J. 
Published: February 2018

In pelvic fracture surgeries, percutaneous screws must be placed accurately for effective fixation and to prevent damage to surrounding tissue structures. Fluoroscopy is currently used to image the pelvis to provide guidance, but this produces harmful ionising radiation and does not allow three-dimensional (3D) visualisation. Ultrasound offers three-dimensional, non-ionising, real-time, and inexpensive imaging. It has thus emerged as an alternative to fluoroscopy for intraoperative imaging in computer-assisted orthopaedic surgery (CAOS). However, ultrasound-based surgical guidance is challenging because ultrasound produces inherently noisy images with limited field-of-view. While several techniques have been proposed to improve bone clarity in ultrasound scans, there is limited work on enhancing ultrasound’s field-of-view for CAOS. In particular, improving the field-of-view for surgical guidance for pelvic fracture surgeries would be needed to achieve accurate and reliable registration to preoperative data, and accurate screw placement in the pelvis.We propose and evaluate the feasibility of a trackerless method for stitching volumetric ultrasound to achieve an extended field-of-view. Stitching is performed using corresponding features in the overlap between three ultrasound volumes, extracted using an implementation of the 3D scale-invariant feature transform. The volumes are processed using confidence-map weighted phase symmetry detection. Alignment between the volumes is calculated using coherent point drift rigid registration.We succeeded in extending the field-of-view of 3D ultrasound by creating a 39×43×115mm volume from three initial overlapping volumes, with reasonable overall accuracy. We show a mean post-registration surface error of 0.54mm, compared to 0.33mm achieved by previous tracking-based stitching. Our method achieved a mean distance error of 5.1%, compared to 2% in a similar tracked and 3D SIFT-based technique. Our stitching method does not use tracking, thus contributing towards simpler surgical navigation.

Published: February 2018

The glenohumeral joint is an important joint with large mobility of the human upperextremity. In shoulder arthroplasty patients often has an unsatisfactory outcome. In order to understand the biomechanical complexity of the shoulder, a novel computer controlled experimental shoulder simulator with an innovative muscle control were constructed. The main component of the simulator includes the active pneumaticmuscles to replicatethe deltoid and the rotator-cuff function and two springs as passive muscle. The aim of this study is to evaluate the impact of a variation of shoulder joint geometries on shoulder biomechanics in the basis of motion analysis. The radius of the glenoid cavity varied from 28-33mm with 2.5mm increment while the radius the humeral head are varied from 20.1-25.1 with 2.5mm increment. The “teach-in” function of the simulator allows an operator to assign the movement to the simulator where the lengths of the pneumatic muscles are recorded. Then the simulator repeats the assigned movement according to the recorded muscles length. The daily living activities includes abduction/adduction, internal/external rotation with adducted arm, and circumduction. The results show promising repeatability of the simulator with minor deviation. However, damage on the surface of the humeral head has been found which should be further studied for both shoulder behavior investigation and the shoulder simulator optimization. Therefore, this study is a decent initial study toward the verification of the simulator and lead to a better understanding of shoulder biomechanical behavior to cope with the clinical problems in the future.

Published: February 2018

The treatment of joint-fractures is a common task in orthopaedic surgery causing considerable health costs and patient disabilities. Percutaneous techniques have been developed to mitigate the problems related to open surgery (e.g. soft tissue damage), although their application to joint-fractures is limited by the sub-optimal intra-operative imaging (2D-fluoroscopy) and by the high forces involved. Our earlier research toward improving percutaneous reduction of intra-articular fractures has resulted in the creation of a robotic system prototype, i.e. RAFS (Robot-Assisted Fracture Surgery) system.We propose a robot-bone attachment device for percutaneous bone manipulation, which can be anchored to the bone fragment through one small incision, ensuring the required stability and reducing the “biological cost” of the procedure. The device has been evaluated through the reduction of 9 distal femur fractures on human cadavers using the RAFS system.
