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…
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…
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…
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…
Key Points: Weight Bearing CT (WBCT) provides critical data otherwise missed in weight bearing radiographs when trying to understand the true impact of a fracture on joint stability. Computational biomechanics, when paired with bilateral WBCT imaging, provides a better understanding…
Key Points: Cone Beam CT (CBCT), specifically WBCT three-dimensional (3D) visualization approach allows for a more accurate assessment of foot alignment with attention to planus, cavus, varus or valgus deformities. Post-operatively, weight bearing CT (WBCT) has the potential to better…
Key Points: Cone Beam Computed Tomography (CBCT), a three-dimensional (3D) imaging modality, can readily evaluate complex joint structures. The most important radiographic (X-Ray) criterion used in surgical decision making for osteoarthritis is joint space narrowing (JSN), or the loss of…
Key Points: Cone Beam CT (CBCT) is superior in assessing bony structures compared to magnetic resonance imaging (MRI) In this study, there was a 40% rate of discrepancy when grading knee subchondral insufficiency fractures on CBCT vs. MRI, with MRI…
Key Points: WBCT 3D Measurements volumetric measurements of the syndesmosis have shown to have a high specificity (83.3%) and sensitivity (95.8%) for the diagnosis of subtle injuries. Manual 3D WBCT volume measurement of syndesmosis, a promising method to detect instability,…
Key Points: The most important advantage of weight bearing CT (WBCT), which utilizes cone beam CT (CBCT) technology (a three-dimensional (3D) imaging modality) is immediate access to 3D images, resulting in faster and better diagnostic capabilities. Up to 40% of…
