April 2019

End date:
December 2019

Funding:

Coordinator:

Summary

Altered scapulothoracic alignment may be a contributing pathoanatomic factor to the development of the B2 pattern of osteoarthritis. The purpose of this study is to use a patient-specific 3D measurement technique coupling medical imaging and optical motion capture to evaluate and compare scapulothoracic alignment in patients with B2 glenoids. The results of this study may improve our understanding of glenohumeral pathoanatomy and posterior glenoid erosion patterns, and assist with osteoarthritis prevention.

In this project, Artanim is responsible for dynamically simulating shoulders from kinematic data.

Coordinator:

Summary

The goal of this project is to simulate reverse shoulder prostheses (RSA) to evaluate the variability of several biomechanical factors and the impact on the range of motion. In particular, we are interested in evaluating the effect of glenoid lateralization, humeral inclination and critical shoulder angle (CSA). These computer-assisted simulations will provide operating parameters which aim to minimize the onset of articular conflicts and luxations.

In this project, Artanim is responsible for dynamically simulating reverse shoulder prostheses from kinematic data.

Surgical planning solutions

Project Info

Start date:
November 2014

End date:
October 2016

Funding:
Private

Coordinator:
Artanim

Summary

The goal of this project is to develop several surgical planning tools taking into account both the anatomy and kinematics of the patient’s joint. We intend to continue and extend our previous research works by integrating them into a 3D surgical planning solution, called ArthroPlanner, which could be used in clinical routine and could thus directly benefit patients.

This project mainly aims at developing solutions for the dynamic planning of the hip and shoulder and to extend our work to the knee.

Dynamic evaluation of instability

Project Info

Start date:
August 2014

End date:
July 2016

Funding:
La Tour Hospital

Coordinator:
Artanim

Summary

Shoulder instability is a common pathology in young or athletic adult that results in chronic dislocations or subluxations. When multiple dislocations episodes occur, surgical treatment is indicated. But this treatment really stabilizes the joint or only prevents it to dislocate?

The objective of this study is to investigate and compare the shoulder stability in patients with anterior instability by performing a dynamic motion capture analysis before and after surgical treatment. The results of this study will provide a better understanding of this disease, and evaluate the effectiveness of the proposed surgical treatment.

Thoracic Outlet Syndrome

A dynamic analysis

Project Info

Start date:
March 2014

End date:
December 2014

Funding:
La Tour Hospital

Coordinator:
Artanim

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.
