Age-matched healthy volunteers (42 males 42 females, average age 65 years) without OA were included the study. Subjects underwent physical examination on their standing full-limb radiography anthropometric measurements. Linear, kinetic, kinematic parameters compared using three-dimensional, 12-camera motion capture system. Gait evaluated with multiple regression analysis....
Background: Radiographic examination is a widely used evaluation method in the orthopedic clinic. However, conventional radiography alone does not reflect dynamic changes between foot and ankle segments during gait. Multiple 3-dimensional multisegment models (3D MFMs) have been introduced to evaluate intersegmental motion of foot. In this study, we evaluated correlation static radiographic indices indices. Methods: One hundred twenty-five females were tested. Static radiographs full-leg...
Background: Total ankle replacement (TAR) and arthrodesis (AA) are usually performed for severe arthritis. We compared postoperative foot segmental motion during gait in patients treated with TAR AA. Methods: Gait analysis was 17 7 undergoing AA, respectively. Subjects were evaluated using a 3-dimensional multisegmental model 15 markers. Temporal parameters calculated. The maximum minimum values the differences hallux, forefoot, hindfoot, arch 3 planes (sagittal, coronal, transverse) between...
Abstract Background Although there have been reports that diabetes affects the prevalence of sarcopenia, no studies examined relationship between sarcopenia and mortality in patients undergoing leg amputation. The purpose this study is to determine whether rate diabetic foot Methods From among who underwent limb amputation for complications, included 167 abdominal CT within 1 year We defined using sex‐specific cut‐off points L3 skeletal muscle index. 5‐year survival was analyzed. All were...
Background: An infected Achilles tendon after repair is particularly difficult to treat because of the poor vascularity as well thin surrounding soft tissue. For treatment an following repair, we first focused on complete debridement and then promoted fibrous scar healing using functional treatment. Methods: We retrospectively reviewed all medical records 15 tertiary referral patients with postoperative infection occurring between 2007 2012. The mean follow-up time was 33 months (range, 22...
Background: The purpose of this study was to evaluate clinical outcomes and the biomechanical function foot ankle at skeletal maturity patients treated for atrophic-type congenital pseudarthrosis tibia (CPT) compared with healthy young adult controls. Methods: Twenty-four (mean age 19.1 years) who had undergone Ilizarov treatment unilateral CPT were twenty-four controls 19.6 years). All participants evaluated using validated outcome questionnaires, radiographs, physical examination,...
Multiple epiphyseal dysplasia (MED) is a genetically heterogeneous group of diseases characterized by variable degrees abnormality primarily involving the hip and knee joints.
