End Stage Ankle Arthritis End-stage ankle arthritis occurs when there is loss of cartilage at the tibiotalar joint. Post-traumatic ankle arthritis is the most common etiology. A weight bearing CT scan can: Allow for accurate assessment of malalignment and congruency…
Syndesmosis A syndesmotic ankle sprain, also known as high ankle sprain, is an injury to one or more of the ligaments comprising the distal tibiofibular syndesmosis. A weight bearing CT scan can: Provide increased sensitivity and specificity over radiographs. Differentiate…
Charcot Arthropathy Charcot arthropathy is characterized by a destructive process that affects the bones, joints, and soft tissues of the foot and/or ankle in patients with neuropathy. A weight bearing CT scan can: Assist in early detection and aid in…
Hallux Valgus Hallux valgus is a three-dimensional deformity of the first ray in which the first metatarsal moves into varus, pronates, and dorsiflexes. This deformity affects the 1st metatarsophalangeal (MTP) joint and is often accompanied by significant functional disability &…
Key Points: Weight Bearing (WB) radiographs are limited by 1) their 2D nature and 2) knee positioning. X-Ray (XR) beam angle differs by person and can be unreliable. Weight Bearing CT (WBCT) imaging provides three dimensional (3D) images of the…
Dr. Cristian Ortiz, MD, a foot and ankle orthopedic surgeon at Clinica Universidad de los Andes, Chile, explained how he and his colleagues are using Weight Bearing Computed Tomography (WBCT) imaging in various research initiatives at the CurveBeam AI exhibit at…
Key Points: When evaluating midfoot arthritis osteoarthritis (OA), Weight Bearing X-Ray shows many false negatives and false positives, even when read by a musculoskeletal (MSK) radiologist, as compared to weight bearing CT (WBCT). WBCT is diagnostically and clinically superior to weight…
Knee osteoarthritis (OA) clinical trials results show that weight bearing CT (WBCT) imaging may offer new insights into OA pathology beyond what plain radiographs and MRI can provide. Some of these findings could immediately be translated into clinical practice as…
Key Points: While magnetic resonance imaging (MRI) adequately detects the size and presence of osteophytes (OPs) in the medial tibio-femoral compartment, it underestimates OPs in all other knee compartments of osteoarthritic patients. CT may be helpful in the assessment of…
