Background: We do not yet fully understand how the subtalar joint position is related to varus osteoarthritic ankle joint. The purposes of this study were (1) investigate coronal orientation calcaneus relative talus according osteoarthritis stage, talar tilt (TT), and (2) determine if there TT threshold at which apparent compensation begins fade. Methods: retrospectively reviewed 132 ankles that underwent weightbearing computed tomography (WBCT) for osteoarthritis. TT, inclination angle...
The transfibular approach is a common procedure for tibiotalar fusion. However, this technique has several concerns: inadequate stability to resist rotational and shearing forces, fibula suboptimal bone grafting, an onlay fibular graft that might prevent impacting cause distraction. We present modified using partial resection graft, which may address these potential problems. This study aimed evaluate whether the ankle joint well fused with neutral alignment functionally improved at final...
T-score discordance between the spine and hip is commonly observed when dual energy X-ray absorptiometry (DXA) used to diagnose osteoporosis. However, information scarce regarding prevalence risk factors for this problem in Korea. This study evaluated of major/minor associated elderly Korean patients with osteoporotic vertebral compression fractures (OVCFs).This included 200 (37 men, 163 women) treated thoracic or lumbar January 2015 August 2021. DXA was performed examine T-scores determine...
Tibiotalocalcaneal arthrodesis is an established surgical procedure for treating patients with end-stage ankle joint arthritis and subtalar arthritis. Although it greatly relives pain, a major drawback loss of range motion. known to restrict additional compared tibiotalar arthrodesis, there lack gait analysis studies comparing the two methods. This study aimed evaluate differences in kinematics foot joints between tibiotalocalcaneal arthrodesis. We also preoperative postoperative statuses...
Degenerative osteoarthritis of the knee usually shows arthritic change in medial tibiofemoral joint with severe varus deformity. In total arthroplasty (TKA), release technique is often used for achieving mediolateral balancing. But, a more knee, there are difficult technical problems. Bony resection proximal tibia (MPT) as an alternative soft tissue balancing was assessed terms its effectiveness and possibility quantification.TKAs were performed 78 knees (60 patients) vertical bone MPT from...
Purpose: Smart insoles are wearable devices that inserted into shoes.Smart with built-in pressure and acceleration sensors can measure the plantar pressure, stride length, walking speed.This study evaluated validity reliability of measurements smart during on flat ground.Materials Methods: Twenty one subjects were included in this study.After wearing insoles, I-SOL ® (Gilon, Seongnam, Korea), walked a 10 m corridor six times at rate 100 steps/min, middle three steps, free from direction...
In clinical fields, many types of insoles are used to not only realign movement patterns, but also treat pressure-related foot diseases. However, the characteristics and plantar pressure in each type insole still unclear. Therefore, aim this study was validate pressure-relieving effect three representative (metatarsal padding [MPI], lateral heel wedge [LHI], arch support [ASI]) asymptomatic men.A total 35 feet men with a mean age 23.4 ± 2.0 years were included. Pedobarographic data evaluated...
Alkaptonuria is an extremely rare autosomal recessive metabolic disorder characterized by dark urine, ochronosis, and arthritis of the spine major joints. We report a case ochronotic observed during total knee replacement surgery in 65-year-old male patient with no relevant medical history. Based on literature review, this first reported Korea.
Purpose: Foot pressure measurement devices are used widely in clinical settings for plantar assessments.Despite the availability of various devices, studies evaluating inter-device reliability limited.This study compared measurements obtained from HR Mat (Tekscan Inc.) and EMED-n50 (Novel GmbH). Materials Methods:The involved 38 healthy male volunteers.The participants were categorized into two groups based on Meary's angle standing foot lateral radiographs: those with normal feet (angles...
The role of vascular smooth muscle cells (VSMCs) in calcification, which is related to chronic kidney disease (CKD), has been studied greater detail the major arteries relative peripheral arteries. We compared calcifying characteristics VSMCs non-pathologic patients with severe artery (PAD). isolated from posterior tibial 10 CKD who underwent below-knee amputation for critical limb ischemia (CLI). Using normal human aortic as a control group, we cultured and high phosphate media days,...
Surgeons have been reluctant to perform crossed-pin fixation for displaced pediatric supracondylar humeral (SCH) fractures because it carries a risk of iatrogenic ulnar nerve injury. This study aimed introduce lateral-exit SCH and evaluate its clinical radiological outcomes, with particular focus on injuries. Children who underwent between 2010 2015 were retrospectively reviewed. Lateral-exit involved the introduction medial pin from epicondyle, as in conventional method, followed by pulling...
Category: Hindfoot; Ankle Arthritis Introduction/Purpose: Although intramedullary nailing is a popular method for tibiotalocalcaneal (TTC) arthrodesis, nonunion one of the most commonly reported complications. The purpose this study was to evaluate fusion rate, improvement in functional outcomes, and occurrence complications TTC arthrodesis using retrograde with partial fibulectomy onlay bone graft technique. Methods: We retrospectively reviewed 26 consecutive patients who underwent proposed...
Abstract Background The biomechanics of the hindfoot in ankle osteoarthritis (OA) are not yet fully understood. Here we aimed to identify motion a gait analysis using multi-segment foot model (MFM) according OA stage or alignment by presence subtalar compensation. Methods We retrospectively reviewed medical records, simple radiographs, and MFM data 54 ankles admitted our hospital for treatment advanced OA. Spatiotemporal parameters three-dimensional motions segment were analyzed sex, age,...
