Filename: /SSM Short description: ShapeWorks project folder containing files for the statistical shape model (SSM) 2. File Download Instructions: To retrieve the data, download file 20251001_DownloadScript_Anderson.txt to your machine, open a command line terminal and run the following command: wget -I 20251001_DownloadScript_Anderson.txt For more information on running this command, visit https://gnuwin32.sourceforge.net/packages/wget.htm 3. Relationship between files: The Femur SSM data repository is a collection of: a. Participant-specific files: i. hip (or isolated femur for dod participants) 3D clinical computed tomography (CT) or magnetic resonance (MRI) images (.nii.gz) ii. surface files of the proximal femur associated with medical imaging files (.vtk) b. ShapeWorks project files: i. subject-specific correspondence models (.particles) ii. proximal femur cutting planes (made up of 3 or more points) (.json) iii. groomed surface models (they have been reflected and aligned as needed) (.vtk) These files are organized into a variety of folders based on the trial participant they were derived from. Participants form three cohorts; athletes, controls, and patients. The demographic information for each participant is captured in the Participant_Demographics excel file. For a detailed description of participant selection, data collection, and data processing methods, please refer to https://doi.org/10.1177/23259671241309604. Files within each folder of the Cam FAIS Biomechanics data repository are organized using the following structure, where SubjID refers to the participant's group followed by the participant number (03, 04, 05...): Femur_SSM ├─Participant_Demographics demographics (.xlsx) ├───Data │ └───SubjID │ ├─surface_meshes surface meshes (.vtk) │ └─SubjID_images CT/MRI image stack (.nii.gz) └───SSM ├─Femur_SSM ShapeWorks project file (.xlsx) ├─constraints cutting planes (.json) ├─groomed aligned surface models (.vtk) └─Femur_SSM_particles orrespondence models (.particles) The surface mesh files, particle files, constraint files, and CT/MRI files in each folder are described in following sections. Surface models of different bones were derived from MRI or CT image files. 4. Additional related data collected that was not included in the current data package: NA 5. Are there multiple versions of the dataset? No -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: The Femur SSM data repository is a collection of hip 3D clinical computed tomography (CT) or magnetic resonance (MRI) images (.nii.gz), associated surface files of the proximal femur (.vtk), and ShapeWorks project files: cutting plane files (.json), groomed surface files (.vtk), and correspondence models (.particles). For a detailed description of participant selection, data collection, and data processing methods, please refer to: https://doi.org/10.1177/23259671241309604 2. Methods for processing the data: CT images were collected in a supine position and segmented to create surface files of the proximal and distal femur, as well as the ipsilateral hemipelvis. In vivo motion of the pelvis and femur bones of each participant were captured using markerkelss biplane videoradiography during self-selected speed level-walking, incline (5 degrees) walking as well as during functional hip joint center (FHJC), abduction, inversion, and everion tasks. Joint angles, joint translations, and pelvic rotation angles were calculated using a custom script in MATLAB.

Instrument- or software-specific information needed to interpret the data: How to Load Femur SSM Project in ShapeWorks Studio i. To open the provided shape model in Shapeworks, you will only need the SSM subfolder from the repository. Once downloaded locally, do not edit the files within the SSM subfolder. ii. Install ShapeWorks following directions provided in the following link: How to install ShapeWorks . iii. Once ShapeWorks is fully installed, open ShapeWorks a. From the main window, select “Open Existing Project” b. Search for the following file (in you local computer): FemurSSM\SSM\Femur_SSM.xlsx. Once you have the Femur_SSM.xlsx spreadsheet selected, select “Open” iv. If the Femur_SSM project has loaded correctly, you will see all the subjects’ groomed surface models along with their correspondence particles and cutting planes. v. For more information, please refer to the ShapeWorks main page. 4. Standards and calibration information, if appropriate: An MRI scan of the proximal femurs was obtained for each athlete. All scanning was performed on a Siemens 3T Magnetom Prisma Fit using a 3D double echo steady state (DESS) sequence (512 × 512 × 288 matrix, 0.7-mm slice thickness, 0.7-mm3 voxel resolution, 16.3-ms repetition time, 4.7-ms echo time, and 25° flip angle). For all participants, 3D models of the proximal femur of the dominant limb were created via segmentation using Amira 6.0.1 (Thermo Fisher Scientific). The proximal femurs of controls and patients were imaged with CT and reconstructed through segmentation. The previous studies used to collect the controls and patients utilized CT. To eliminate radiation exposure for volumetric imaging, we used a high-resolution MRI sequence instead. The DESS MRI sequence has been validated, with segmentation reconstructions showing accuracy similar to that of a CT.
