Progressive Collapsing Foot Deformity Progressive Collapsing Foot Deformity (PCFD), previously known as adult-acquired flatfoot deformity, is a multifactorial disorder characterized by concurrent multiplanar bony deformities. These deformities include, but are not limited to, hindfoot valgus, flattening of the medial longitudinal…
Midfoot Arthritis Midfoot arthritis occurs when there is loss of cartilage at the tarsometatarsal and/or navicular-cuneiform joints. It has the potential to cause significant pain, disability, and decreased quality of life. The most common etiology is posttraumatic degeneration, but primary…
A paper published in Foot and Ankle International is calling for a weight bearing CT (WBCT) reference standard for post-operative evaluation of total ankle arthroplasties. With the rising popularity of softwares that can semi-automatically create 3D models from WBCT scans…
Lisfranc Injuries A Lisfranc injury is characterized by an injury to the ligament that connects the medial cuneiform with the 2nd metatarsal base (Lisfranc ligament). Often, there are associated midfoot fractures. Unstable Lisfranc injuries left untreated can result in chronic…
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…
