  • A physically based trunk soft tissue modeling for scoliosis surgery planning systems 

    Assi, Kondo C.; Grenier, Sébastien; Parent, Stefan; Labelle, Hubert; Cheriet, Farida (Elsevier, 2015-03-01)
    One of the major concerns of scoliotic patients undergoing spinal correction surgery is the trunk's external appearance after the surgery. This paper presents a novel incremental approach for simulating postoperative trunk shape in scoliosis surgery. ...

  • Prediction of scoliosis curve type based on the analysis of trunk surface topography 

    Seoud, Lama; Adankon, Mathias M.; Labelle, Hubert; Dansereau, Jean; Cheriet, Farida (2010-04)
    Scoliosis treatment strategy is generally chosen according to the severity and type of the spinal curve. Currently, the curve type is determined from X-rays whose acquisition can be harmful for the patient. We propose in this paper a system that can ...

  • Reliability of a quantitative clinical posture assessment tool among persons with idiopathic scoliosis 

    Fortin, Carole; Ehrmann Feldman, Debbie; Cheriet, Farida; Gravel, Denis; Gauthier, Frédérique; Labelle, Hubert (Elsevier, 2012-03-01)
    Objective To determine overall, test–retest and inter-rater reliability of posture indices among persons with idiopathic scoliosis. Design A reliability study using two raters and two test sessions. Setting Tertiary care paediatric ...

  • Scoliosis curve type classification from 3D trunk image 

    Adankon, Mathias M.; Dansereau, Jean; Parent, Stefan; Labelle, Hubert; Cheriet, Farida (2012-02-23)
    Adolescent idiopathic scoliosis (AIS) is a deformity of the spine manifested by asymmetry and deformities of the external surface of the trunk. Classification of scoliosis deformities according to curve type is used to plan management of scoliosis ...

  • Scoliosis Follow-Up Using Noninvasive Trunk Surface Acquisition 

    Adankon, Mathias M.; Chihab, N; Dansereau, Jean; Labelle, Hubert; Cheriet, Farida (2013-03-13)
    Adolescent idiopathic scoliosis (AIS) is a musculoskeletal pathology. It is a complex spinal curvature in a 3-D space that also affects the appearance of the trunk. The clinical follow-up of AIS is decisive for its management. Currently, the Cobb angle, ...

  • Screening for adolescent idiopathic scoliosis: an information statement by the scoliosis research society international task force 

    Labelle, Hubert; Richards, Stephens B.; De Kleuver, Marinus; Grivas, Theodoros B.; Luk, Keith D.K.; Wong, Hee Kit; Thometz, John; Beauséjour, Marie; Turgeon, Isabelle; Fong, Daniel Y.T. (2013-10-31)
    Background: Routine screening of scoliosis is a controversial subject and screening efforts vary greatly around the world. METHODS: Consensus was sought among an international group of experts (seven spine surgeons and one clinical epidemiologist) ...

  • Semiautomatic detection of scoliotic rib borders from posteroanterior chest radiographs 

    Plourde, Frédéric; Cheriet, Farida; Dansereau, Jean (2011-09-15)
    3-D assessment of scoliotic deformities relies on an accurate 3-D reconstruction of bone structures from biplanar X-rays, which requires a precise detection and matching of anatomical structures in both views. In this paper, we propose a novel semiautomated ...

  • Simulation of the postoperative trunk appearance in scoliosis surgery 

    Dionne, Olivier; Assi, Kondo C.; Grenier, Sébastien; Labelle, Hubert; Guibault, François; Cheriet, Farida (IEEE, 2012-05-01)
    Persistence of external trunk asymmetry after scoliosis surgical treatment is frequent and difficult to predict by clinicians. This is a significant problem considering that correction of the apparent deformity is a major factor of satisfaction for the ...

  • Statistical model based 3D shape prediction of postoperative trunks for non-invasive scoliosis surgery planning 

    Assi, Kondo C.; Labelle, Hubert; Cheriet, Farida (Elsevier, 2014-05-01)
    One of the major concerns of scoliosis patients undergoing surgical treatment is the aesthetic aspect of the surgery outcome. It would be useful to predict the postoperative appearance of the patient trunk in the course of a surgery planning process ...

  • Towards Non Invasive Diagnosis of Scoliosis Using Semi-supervised Learning Approach 

    Seoud, Lama; Adankon, Mathias M.; Labelle, Hubert; Dansereau, Jean; Cheriet, Farida (Springer Berlin Heidelberg, 2010)
    In this paper, a new methodology for the prediction of scoliosis curve types from non invasive acquisitions of the back surface of the trunk is proposed. One hundred and fifty-nine scoliosis patients had their back surface acquired in 3D using an optical ...

  • Validity of a Quantitative Clinical Measurement Tool of Trunk Posture in Idiopathic Scoliosis 

    Fortin, Carole; Ehrmann Feldman, Debbie; Cheriet, Farida; Labelle, Hubert (2010-09-01)
    STUDY DESIGN: Concurrent validity between postural indices obtained from digital photographs (two-dimensional [2D]), surface topography imaging (three-dimensional [3D]), and radiographs. OBJECTIVE: To assess the validity of a quantitative clinical ...
