Biochemical T2* MR quantification of ankle arthrosis in pes cavovarus.
Pes cavovarus affects the ankle biomechanics and may lead to ankle arthrosis. Quantitative T2 STAR (T2*) magnetic resonance (MR) mapping allows high resolution of thin cartilage layers and quantitative grading of cartilage degeneration. Detection of ankle arthrosis using T2* mapping in cavovarus feet was evaluated. Eleven cavovarus patients with symptomatic ankle arthrosis (13 feet, mean age 55...
متن کاملAnkle joint pressure in pes cavovarus.
A cavovarus foot deformity was simulated in cadaver specimens by inserting metallic wedges of 15 degrees and 30 degrees dorsally into the first tarsometatarsal joint. Sensors in the ankle joint recorded static tibiotalar pressure distribution at physiological load. The peak pressure increased significantly from neutral alignment to the 30 degrees cavus deformity, and the centre of force migrate...
متن کاملAnkle joint pressure changes in a pes cavovarus model: supramalleolar valgus osteotomy versus lateralizing calcaneal osteotomy.
BACKGROUND A fixed cavovarus foot deformity can be associated with anteromedial ankle arthrosis due to elevated medial joint contact stresses. Supramalleolar valgus osteotomies (SMOT) and lateralizing calcaneal osteotomies (LCOT) are commonly used to treat symptoms by redistributing joint contact forces. In a cavovarus model, the effects of SMOT and LCOT on the lateralization of the center of f...
متن کاملChanges in Dynamic Pedobarography after Extensive Plantarmedial Release for Paralytic Pes Cavovarus
PURPOSE Plantarmedial release and first ray extension osteotomy are often combined to treat paralytic cavovarus foot deformity. The purpose of this study is to evaluate the effect of additional first ray extension osteotomy in terms of dynamic pedobarography. MATERIALS AND METHODS We reviewed findings of pre- and postoperative plain radiography and dynamic pedobarography for 25 patients in wh...
متن کاملFunctional limitations of patients with end-stage ankle arthrosis.
BACKGROUND Arthritis and other rheumatic conditions are the leading causes of disability among adults in the United States. The purpose of this report was to describe the self-reported functional limitations of a group of patients with end-stage ankle arthrosis. METHOD Patients who presented for operative management of end-stage ankle arthrosis at the University of Minnesota and Harborview Me...
