Summary

ArthroPlanner aimed to develop patient-specific surgical planning tools that combine 3D anatomy with functional joint kinematics. Building on Artanim’s previous research in medical imaging, motion capture and biomechanical simulation, the project explored how dynamic information could complement conventional static anatomical planning and support more personalized clinical decision-making.

A major application focused on shoulder surgery and the development of a computer-assisted planning solution for acromioplasty. Patient-specific 3D anatomical models and joint simulations were used to identify areas of subacromial impingement and estimate the bone resection required during surgery. This approach was subsequently evaluated through clinical studies comparing planned and actual resections as well as guided and conventional freehand acromioplasty.

A similar planning solution was developed for femoroacetabular impingement (FAI) of the hip. Patient-specific 3D models and joint simulations were used to identify impingement zones during movement and to support planning of the bone resection required to restore functional range of motion. Unlike the acromioplasty application, this hip planning solution was not clinically evaluated.

The project also extended these patient-specific modeling techniques to the knee. Motion capture, magnetic resonance imaging and biomechanical optimization were combined to improve the estimation of knee kinematics at high flexion angles and to analyze structures such as the posterior cruciate ligament during static and dynamic movements.

More broadly, ArthroPlanner contributed to Artanim’s research toward dynamic surgical planning solutions for the hip, shoulder and knee, integrating patient-specific anatomy and movement into clinically relevant 3D tools.

Summary

Anterior shoulder instability is a common condition in young and athletic adults and can lead to recurrent dislocations or subluxations. When instability becomes recurrent, surgical treatment may be required. Beyond preventing further dislocation, an important question is whether surgery also restores normal shoulder mechanics and joint stability during movement.

This study investigated shoulder kinematics in patients with anterior instability using dynamic motion capture before and after surgical treatment. By comparing joint motion pre- and post-operatively, the project aimed to better characterize the biomechanical effects of instability and assess how surgical treatment influences shoulder stability and movement.

Summary

Thoracic Outlet Syndrome investigated the biomechanical mechanisms that may contribute to thoracic outlet syndrome (TOS), a condition associated with compression of nerves or blood vessels in the region between the clavicle and upper rib cage.

The study focused on dynamic analysis of the shoulder complex to better understand how repetitive arm movements and individual anatomy may influence this compression. Motion capture was combined with medical imaging, including CT and MRI, to reconstruct patient-specific anatomy and analyze shoulder movement in symptomatic patients.

By integrating anatomical and kinematic information, the project aimed to improve the functional assessment of TOS and provide a better understanding of the relationship between shoulder motion and structures involved in the thoracic outlet.
