Summary

Thoracic outlet syndrome (TOS) is a rare condition that involves pain in the neck and shoulder, numbness and tingling of the fingers. It happens when the nerves or blood vessels are compressed in the thoracic outlet which is the area between the rib cage and clavicle.

The goal of this study is to better understand certain causes of TOS by performing a dynamic simulation of the shoulder complex. Repetitive arm and shoulder movements, as well as anatomical defects can play a role in the development of TOS. In this study, motion capture and medical imaging (CT, MRI) are combined to improve assessment of this condition in symptomatic patients.

Summary

Strengthening of shoulder muscles in rehabilitation protocols and sport practice can be achieved by a wide range of different exercises and several types of technique. In presence of a rotator cuff lesion, articular cartilage pathology or instability, recommendations for design of a shoulder strength training protocol aim at avoiding or minimizing subacromial impingement and stress on the articular cartilages or labrum. Very limited objective data is at disposable to emit such recommendations.

The goal of this study is to capture and simulate 30 to 50 rehabilitation exercises to study the impact on the glenohumeral joint (e.g. cartilage’s compression, incidence of subacromial impingement) and rotator cuff (e.g. tendon lengthening of the subscapularis, supraspinatus, infraspinatus and teres minor). Ultimately, this study will better target rehabilitation exercises of the shoulder.

Summary

The shoulder has the widest range of motion of any joint in the body, but at the cost of inherent instability causing pain and functional disability. To better understand the mechanisms involved in shoulder stability, an in-depth analysis of the shoulder kinematics is instrumental. Therefore, the project aims at developing a new kinematic model to reliably evaluate the three-dimensional motion of the shoulder based on motion capture. To set up and evaluate the kinematic model, a clinical study involving tennis players is performed.

The expected results could open up new possibilities to orthopedic surgeons in order to improve assessment and treatment of patients with shoulder functional abnormalities.

Summary

MyHip aims at creating a complete solution for the planning and execution of total hip arthroplasty (THA). By considering preoperatively the kinematics of the prosthetic hip and pelvis tilting, accurately modeled from the patient morphology, a dynamic planning for THA can be defined. This novel planning provides operating parameters which aim to minimize the onset of articular conflicts and (sub-)luxations. Furthermore, the creation of intra-operative guidance tools for the faithful reproduction of the surgical planning strengthens this dynamic planning for THA.

In this project, Artanim is responsible for the development of the dynamic simulation module of the prosthetic hip driven by motion capture data.

Summary

Many patients wonder about the risks related to sexual activity after total hip arthroplasty (THA), but this issue remains rarely discussed between patients and surgeons. To date, the relative risk of prosthetic or bony impingement and joint instability during sexual activities after THA is unknown. Hip range of motion necessary to perform sexual positions has also never been quantified.

The goal of this study was to obtain realistic motion data for 12 common sexual positions and to evaluate relative risk of impingement and joint instability during their practice. We therefore conducted an in-vivo study with two volunteers using motion capture and magnetic resonance imaging. The data obtained were then used for computer simulations of prosthetic hip joint 3D models. Our aim was to provide surgeon or other healthcare professionals with scientifically validated information, as well as specific instructions to answer patient’s inquiries.
