Supine CT May Underestimate Contact Stress in Critical WB Regions of the Acetabulum Compared to Weight Bearing CT
Key Points: Computational models of the hip often omit patient-specific functional orientation when placing imaging-derived bony geometry into anatomic landmark-based coordinate systems for application of joint loading schemes. Significant differences are found when incorporating WBCT-derived data suggesting non-weight bearing (NWB)…
Researchers Aim to Define Standard Values for Measuring Syndesmosis Injury on WBCT
Key Points: Weight Bearing CT (WBCT) allows for bilateral comparative data that is imperative when diagnosing ankle syndesmosis. Side-to-side volume differences of 19% or greater may be indicative of an abnormality. Gender norms are important to consider when evaluating ankle…
Weight Bearing CT: A Game-Changer for Assessment of Knee Instability and ACL Injuries
Weight bearing CT offers a new way to evaluate knee instability and ACL injuries.- a fast, low-radiation, and highly detailed 3D imaging alternative to traditional methods. In a recent talk at AAOS 2025, Dr. Camillo Helito, MD, PhD, Prof highlighted…
Advantages of WBCT Measurement Parameters in Hallux Valgus
When it comes to hallux valgus (bunion) deformity, weight bearing CT provides significant advantages over conventional radiography. "Its ability to provide detailed 3D visualization, coupled with automated measurement techniques and AI integration, allows for a more precise assessment of the…
WBCT-Based Method to Detect Implant Loosening Shows Promise
Key Points: Radiostereometric Analysis (RSA) uses X-Ray and markers inserted into the bone intraoperatively to assess implant migration and fixation. Model-based RSA (MBRSA) improves upon RSA by incorporating 3D implant CAD models. In one study, weight bearing CT (WBCT)-RSA was…
Stay ahead of the Curve with Weight Bearing CT
In the world of orthopedic diagnostics, imaging plays a crucial role in identifying deformities and planning surgical interventions. Conventional radiographs and MRIs have been the standard, but they come with limitations when it comes to understanding the complex, three-dimensional structure…
Measuring Leg Alignment in the Axial Plane with Weight Bearing CT
At the International Weight Bearing CT Society (WBCT) session during the 2024 European Foot & Ankle Society congress in Brussels, Andy Goldberg, OBE, a foot and ankle orthopedic surgeon at The Wellington Hospital in London, England discussed the rotational alignment…
Comparative Analysis of Structural Differences in Progressive Collapsing Foot Deformity With and Without Hallux Valgus
Key Points: Weight Bearing CT (WBCT) helps visualize several structural and alignment differences between Progressive Collapsing Foot Deformity (PCFD) with and without Hallux Valgus (HV). Rotation of the first tarsometatarsal joint, and intrinsic rotation of the first metatarsal bone were…
Cadaveric Diagnostic Study of Subtle Syndesmotic Instability Using a 3-Dimensional Weight Bearing CT Distance Mapping Algorithm
Key Points: Imaging modalities such as plain radiographs (X-Ray), computed tomography (CT), and magnetic resonance imaging (MRI), don’t have the diagnostic accuracy needed to detect syndesmotic widening or subtle instability. Weight Bearing CT (WBCT) imaging when combined with a distance…
