CAS guided RFA can be a safe and effective treatment in OFD like adamantinoma in a child.
Authors: Jutte Paul , Ploegmakers Joris 
Published: February 2018

BackgroundOsteo Fibrous Dysplasia (OFD) like adamantinoma is considered a benign condition that is usually located in the tibia. The condition is mainly found in children and has an association with classical adamantinoma, a malignancy of bone. The preferred treatment is surgical.The lesion often requires a segment resection to eradicate the tumor as the margins of healthy bone are often too small to save continuity of bone and the lesion is located in the cortical area. Segmental resection in a young child is associated with a high complication rate.To avoid these complications it would be ideal to spare the continuity of tibial bone by treating the tumor in situ. Radiofrequency Ablation (RFA) may be a safe and reliable option for treatment of OFD like adamantinoma, without vital tumor spill.To ensure accurate ablation, the guidance and monitoring of antenna placement, planning and execution are performed with computer assisted surgery (CAS).ResultsTwo young patients with OFD like adamantinoma of the tibia were treated with CAS guided open intra-operative RFA in our institution. Because of the heat generation and the proximity of the skin we performed the procedures half open. In both patients successful local tumor ablation was achieved without complications. At baseline MRI there was no sign of residual tumor activity in either patient.DiscussionFollow-up is short and number of treated patients too low to draw definitive conclusions yet.What we can say is that there is considerable less damage done to the patient if compared to classical open surgery like segmental resection or hemicortical resection.Another great advantage is that it allows accurate local tumor ablation without tumor spill and it does not prohibit a local resection as a plan b if there still is viable local tumor tissue visible on MRI. It allows classical treatment in case of insufficient ablation.ConclusionLocal tumor ablation with RFA has the potential to become a safe and effective treatment alternative in OFD like adamantinoma in a child.

Robotic assisted fixation of sacral fractures – initial experienceUnstable sacral fractures are challenging for orthopaedic trauma surgeons. In most cases percutaneous fixation techniques are utilized after reduction. However, these techniuqes are not risk free mainly due to anatomical considerations. Screw misplacement is quite common and concerning. As spine surgery evolved, a miniature robotic guidance system was successfully utilized in pedicular screw insertion. The aim of the study was to demonstrate th use of the miniature robot in the fixation of unstable sacral fracutres.Patients and Methods: 9 patients with unstable sacral fracutres without significant displacement were eligible for percutaneous fixation. These included 7 traumatic fractures and 2 pathological fractures. All fixation constructs were planned using a preoperative CT scans. The patients were placed prone and the robot was mounted on a Dynamic Reference Bridge (DRB) and a 2 verification fluoroscopic images were taken. The robot was mounted on the DRB and was sent by the computer to point to the desired screw(s) trajectory. The guide wires were inserted through stab wounds and screws were placed subsequently. CT scans were made postoperatively and fluoroscopic and operative time were recorded intraoperatively. Results: Mean patient age was 29 (17-63) number of screws ranged 1-6 (average 2). Mean operative time was 50 min (range 15-90), and average fluoroscopic time was 18 sec (7-42). None was the screw was misplaced. Conclusion: Robotic assisted fixation of sacral fracture is promising. At this time it is limited to nondisplaced fractures.

We propose a new paradigm of human-drone interaction through projecting image on the ground and foot gestures. The proposed technology allowed creating a new type of tangible interaction with drone, e.g., DroneBall game for augmented sport and FlyMap to let a drone know where to fly.We developed LightAir system that makes possible information sharing, GPS- navigating, controlling and playing with drones in a tangible way. In contrast to the hand gestures, that are common for smartphones, we came up with the idea of foot gestures and projected image for intelligent human-drone interaction. Such gestures make communication with the drone intuitive, natural, and safe. To our knowledge, it is the world’s first system that provides the human-drone bilateral tangible interaction. The paper also introduces the novel concept of Drone Haptics.

Published: February 2018

The depth gauge is used in many osteosynthesis surgeries to measure drilled bore depth for screw selection, and has significant limitations. Its use has been shown to contribute to placement of incorrectly sized screws, which can lead to adverse outcomes in patients.We have developed an automatic depth gauge prototype which mounts on an existing surgical drill and makes use of an optical sensor. This builds off previous work in our lab which showed that drilled bore depth could be computed from continuous measurement of drill displacement relative to the bone. We tested our device in animal models and compared it with digital calipers as a gold standard. In a simple porcine model the prototype showed potentially superior performance (mean error 2.05mm, SD 0.67mm) compared with the conventional depth gauge (mean error 0.83 mm, SD 1.55 mm). However, this could not be reproduced in a more realistic porcine model.An automated depth gauge mounted on a conventional surgical drill shows potential as a replacement for the existing depth gauge, but the design needs to be refined for use in an operating room setting.
A Machine Learning Approach to Discriminate Between Soft and Hard Bone Tissues Using Drilling Sounds

Published: February 2018

Bone drilling is conducted in many surgical disciplines such as orthopedics, maxillofacial, and spine surgery. Most of these procedures involve drilling of different bone materials including hard (cortical) and soft (cancellous) tissues. Identifying these tissues is essential for surgeons to minimize damage to underlying nerves and vessels.The sound signal generated during drilling is a valuable source of information that could potentially be employed. Such sounds can be captured readily and easily through non-contact sensors. Therefore, our goal in this preliminary study is to investigate whether drilling sounds can enable us to distinguish between cortical and cancellous tissues.A bovine tibial bone was drilled, and the cortical and cancellous drilling sounds were captured. Each sound record was divided into small windows with a length of 50 ms and a 50% overlap. The window length was selected small, because our intended longer-term application is to provide the surgeon with near-real-time feedback. Short time Fourier Transform (STFT) coefficients were extracted from each window and were averaged accordingly to obtain p features. A support vector machine (SVM) algorithm was used for classification, and its accuracy was evaluated for different number of features (p). Two training/testing scenarios were considered, atlas (ATL) and leave-one-out (LOO).The total accuracies for ATL and LOO were 100% and 93.8% respectively obtained for p=128. Our study on a single specimen demonstrated that it is possible to discriminate between cortical and cancellous bones based on relatively short 50 ms windows of drilling sounds.
Intra-Operative Registration of 3D data capture with pre-operative plan for TKA
Authors: Roberts Benjamin , Kolos Elizabeth 
Published: February 2018

INTRODUCTIONTotal knee arthroplasty (TKA) is widely performed for improving pain and restoring function for patients with osteoarthritis (OA) and over 50000 primary procedures were performed in Australia in 2015 (Annual report 2016). Computer assisted pre-operative planning (CAPP) was introduced to enhance accuracy of rotational and translational alignment of components (Schep 2003). It can be done with 3D bone surface modelling from CT or MRI scans and take kinematics and surgeon work flow into account. Computer assisted intra-operative navigation is also accessed by some surgeons and consists of three elements: software platform, point positions from reference arrays captured and reference device attached to the patient’s bone (Bae 2011).By incorporating CAPP with navigation, a correlation between the patient’s anatomy from pre-operative images can be established by gathering intra-operative anatomical landmarks and/or surface points and is known as registration (Chan 2016). However, identifying landmarks and acquiring images intra-operatively and the registration quality can be time-consuming and/or prone to risk. Custom-designed registration software that could reduce the time and error and be incorporated into the surgical workflow is needed (Chan 2016).The aim of this study was to develop custom registration software using pre-operative planning and intra-operative 3D data capture and validate precision and repeatability using a preliminary Sawbones study.

Consideration of the pre- and post-operative magnitude of the hip joint force R and its orientation Ɵ is of major importance for satisfactory long-term results in total hip arthroplasty. R and Ɵ can be computed by using biomechanical models with adapted geometrical/ anthropometrical parameters taken from clinical X-ray images. The objective of this study was to evaluate the models of Pauwels and Debrunner based on digital reconstructed-radiographs (central projection) from 10 CT-datasets of patients treated with telemetric hip-implants by a comparison to corresponding in-vivo measurements.R and Ɵ were computed for 10 patients with patient-specific geometric/anthropometric parameters. The model adaption was based on 28 anatomical landmarks. The root-mean-square-error of R is smaller for Debrunner (0.59/vs./0.66), and for Ɵ it is smaller for Pauwels’ (4.47/vs./7.78).Mathematical models provide potentially valuable information regarding hip joint mechanics. Regarding R, in all of the 10 patients the predictions of Pauwels’ model are consistently higher than the in-vivo measurements. Debrunner computed R in 8 cases higher and in 2 cases lower than the corresponding in-vivo forces. Pauwels’ and Debrunner showed similar tendencies: in 8 cases an overestimation of R and in 2 cases contrary results. Regarding Ɵ we found that in 5 cases the predictions of Pauwels’ are consistently higher than the in-vivo measurements and also contrary to Debrunner.As previous studies showed, an unambiguous identification of most landmarks in a 2D X-ray image is difficult. The impact of the pelvic tilt on the computational result was not considered in our study. Further investigation of this aspect is part of our ongoing work.
Multi-Dimensional Range-of-Motion-Based Safe Zone for Patient-Specific Total Hip Arthroplasty

Published: February 2018

Proper component alignment is crucial for a successful total hip arthroplasty (THA). Some studies found safe cup orientations and corresponding stem antetorsions based on a defined desired range of motion (ROM) suitable for activities of daily living. These studies either used complex and time consuming 3D simulations or more simple mathematical formulas which cannot be extended to combined motions.With the method introduced in this work, any arbitrary motion can be applied. The ROM specified as the ROM of the femur relative to the pelvis is transformed into the ROM of the prosthesis neck relative to the cup for each cup orientation. For this transformation, the orientation and design of the stem are considered. The comparison of the neck and cup orientations is done using a 2D mapping of a 3D spherical surface which reduces the complexity of the calculation.We found that the femoral antetorsion as well as the neutral stem flexion and adduction have an influence on the resulting safe zone. The result is not just a combined anteversion but a combined orientation. For validating the plausibility of the algorithm, the resulting safe zones are compared to literature. Same results can be achieved using the same input data. Using this technique, a patient-specific safe zone based on the ROM can be derived and adjusted to the stem orientation.

Increasing the population, the number of vehicles, and activities in Gresik Town causing social and economic problems that are highly dependent on road transport. These problems arise because of the imbalance problems such as the high volume of traffic and the increasing number of people living along the Gubernur Suryo Road. The method used in this research is descriptive study. This method used to look for the amount of capacity and degree of saturation that affect the activities on this road. Data collection techniques using observation and geometric data. While the flow of vehicles using MKJI 1997 method. From the effectiveness side, the road capacity is smaller than planned capacity due to the side barriers and the growth rate of the vehicle in line with the population increase. From the identification of problems, volumes of traffic is high, amounted 2969 smp/hour. Performance of road being dropped LOS = 1.91 (F), due to the high volume of traffic that passing through this road is not comparable with the capacity (1548.36 smp/hour) and Degree of Saturation (DS) greatly affects the traffic flow on Gubernur Suryo Road of = 1.91 smp/hour. The high delay and side barrier amounted 317 smp/hour. Side barrier can be resulted from the calculation of total amount divided by the capacity, the result is 0,20 smp/hour. It affects the smoothness of traffic flow because the density of traffic and intersection of roads are not well planned, where the distance of each t-junction is quite far one another. Traffic engineering is used to solve the traffic jam problems on the Gubernur Suryo Road and along the market road. It is expected that the government can curb the tricycles parking and vehicles along the road so that traffic jam can be resolved soon.
