Periacetabular osteotomy is a challenging surgical procedure for treating developmental hip dysplasia, providing greater coverage of the femoral head via relocation of a patient’s acetabulum. Since fluoroscopic imaging is frequently used in the surgical workflow, computer-assisted X-Ray navigation of osteotomes and the relocated acetabular fragment should be feasible. We use intensity-based 2D/3D registration to estimate the pelvis pose with respect to fluoroscopic images, recover relative…

Pose Estimation of Periacetabular Osteotomy Fragments With Intraoperative X-Ray Navigation

The proposed pipeline provides an intraoperative estimate of rigid pose with respect to all anatomical axes, is compatible with minimally invasive incisions, and has no dependence on external fiducials.

Fiducial-Free 2D/3D Registration for Robot-Assisted Femoroplasty

The fiducial-less 2D/3D registration is sufficiently accurate to guide robot assisted femoroplasty, and the biomechanical analysis showed that even with a 4 mm translational deviation from the optimal injection path, the yield load prior to fracture increased by 40%.

Automatic annotation of hip anatomy in fluoroscopy for robust and efficient 2D/3D registration

The first accurately annotated, non-synthetic, dataset of hip fluoroscopy is created by using anatomical annotations produced by a neural network as training data for neural networks and state-of-the-art performance in fluoroscopic segmentation and landmark localization was achieved.

Towards 2D/3D Registration of the Preoperative MRI to Intraoperative Fluoroscopic Images for Visualisation of Bone Defects

A 2D/3D registration pipeline that aims to register preoperative MRI with intraoperative 2D fluoroscopic images for intraoperative visualization applications is proposed and the results suggest that the proposed registration pipeline is capable of achieving reasonable transformation.

A Surgical Robotic System for Osteoporotic Hip Augmentation: System Development and Experimental Evaluation

The experimental results demonstrate the first application of the proposed Robot-Assessment combined Drilling and Injection System (RADIS), incorporating biomechanical planning and intraoperative fiducial-less 2D/3D registration on human cadavers with intact soft tissues.

Fluoroscopy-Guided Robotic System for Transforaminal Lumbar Epidural Injections

The results suggest the feasibility of using the image-guided robotic injection system for spinal orthopedic applications and perform intensive simulation studies to validate the registration accuracy.

The experiments suggest that the modeling, nail selection, and visualization modules yield adequate results and that fluoroscopic image processing with submillimetric accuracy is practically feasible on clinical images.

Periacetabular osteotomy through the pararectus approach: technical feasibility and control of fragment mobility by a validated surgical navigation system in a cadaver experiment

Experimental data suggests the pararectus approach might be an alternative approach for performing periacetabular osteotomy (PAO), allowing for adequate exposure, safe osteotomies and excellent control of structures at risk.

Osteotomy with use of this minimally invasive transsartorial approach appears to be a safe, relatively short surgical procedure associated with a relatively small amount of blood loss and minimal transfusion requirements.

Standardized evaluation methodology for 3D/2D registration based on the Visible Human data set.

Computer Assistance for Pelvic Osteotomies

To assist surgeons performing pelvic osteotomies for the treatment of dysplastic hips, an image guided freehand navigation system has been developed and the visualization aids provided are able to help reduce potential risk and thus increase safety and accuracy for this difficult class of surgical interventions.
