Abstract An indentation system is developed to directly apply loads ranging from 1μN 10 mN and make load–displacement measurements with subnanometre depth capability. This used here in conjunction a commercial atomic force microscope provide in-situ imaging. A three-sided pyramidal (Berkovich) diamond tip has been obtain curve residual depths of the order 1 nm. The data have hardness Young's modulus elasticity for singlecrystal silicon GaAs. Hardness on nanoscales found be higher than that...

The healthcare industry collects large amounts of Healthcare data, but unfortunately not all the data are mined which is required for discovering hidden patterns and effective decision making. We propose efficient genetic algorithm with back propagation technique approach heart disease prediction. This paper has analyzed prediction systems Heart using more number input attributes. System uses medical terms such as Gender, blood pressure, cholesterol like13 attributes to predict likelihood...

Current radiographic classifications for Legg-Calvé-Perthes disease cannot be applied at the early stages of disease. The purpose this study was to quantify perfusion femoral epiphysis in with use magnetic resonance imaging (MRI) and determine if extent epiphyseal can predict lateral pillar involvement mid-fragmentation stage.Twenty-nine patients had gadolinium-enhanced MRI initial stage or fragmentation were followed prospectively. percent whole its third measured by four independent...

Abstract Legg-Calvé-Perthes disease (LCPD), or idiopathic avascular necrosis of the proximal capital femoral epiphysis in children, has a variable presentation and can result significant head deformity that lead to long-term functional deficits. Plain radiographic imaging is crucial diagnosing LCPD guiding treatment. Although etiology remains unknown, evolution been well characterized include phases ischemia, revascularization, reossification. The mechanical weakening during these healing...

Background: In the absence of 3-dimensional gait analysis (3DGA), assessment transverse plane motion lower extremity from sagittal and coronal video has a high degree error. We propose standardized method through vertical video-based (VVGA) to assess position pelvis in transversal plane. This study aims evaluate reliability accuracy VVGA compared with 3DGA for kinematics. Methods: were obtained simultaneously on subjects between ages 6 35 referred center. Gait Deviation Index (GDI) Profile...

Purpose: A majority of ambulant children with cerebral palsy (CP) develop progressive musculoskeletal pathology (MSP) during growth. Fixed flexion deformity at the knee joint (FFDKn) contributes to flexed gait and is prone relapse after index multi-level surgery. This perspective introduces concept “knee surveillance” (KS), defined as a repeated systematic assessment range motion until skeletal maturity. KS aims detect early FFDKn, allowing for intervention minimally invasive techniques such...

To evaluate the mechanosensitivity of muscle satellite cells (MuSCs) and fibro-adipogenic progenitors (FAPs) in cerebral palsy (CP) efficacy drug verteporfin restoring cells' regenerative capacity.

Purpose Hip surveillance programmes for children with cerebral palsy (CP) utilize the migration percentage (MP) measurement to initiate referrals and recommend treatment. This study assesses reliability efficiency of three methods MP on anteroposterior (AP) pelvis radiographs. Methods A total 20 AP radiographs (40 hips) CP were measured by raters two occasions using methods: digital (DM) a Picture Archiving Communication System monitor, computer-aided (CA) templating tool mobile device...

To analyze outcomes of adolescents treated with a periacetabular osteotomies (PAO) minimum 2 years follow-up. Patients undergoing PAO for adolescent hip dysplasia were analyzed preoperatively, 1 and postoperatively. In 32 dysplastic hips significant improvement was seen in all radiographic parameters. Gait speed, flexion pull-off power, abductor moment impulse unchanged postoperatively, whereas strength maintained 85% (abduction) 95% (flexion). The Harris Hip Score increased from 67.1 to...

Abstract Cerebral palsy (CP) describes some upper motoneuron disorders due to non‐progressive disturbances occurring in the developing brain that cause progressive changes muscle. While longer sarcomeres increase muscle stiffness patients with CP compared typically (TD) patients, extracellular matrix (ECM) architecture can stiffness. Our goal was investigate how and ECM impact stiffness, gait joint function CP. Gracilis adductor longus biopsies were collected from children undergoing tendon...

In settings where three dimensional gait analysis is not feasible, observational can provide important information about pathology.  Among the validated scoring systems to organize observations of gait, Edinburgh Visual Gait Score (EVGS) most comprehensive and has favorable psychometrics.  Improvements in mobile videography have created opportunities obtain high-quality slow-motion video a clinic setting.  These videos excellent documentation pathology sagittal, coronal,...

Background: This study assesses the effect of skeletal maturity on development iatrogenic proximal femoral deformity following threaded prophylactic screw fixation in patients presenting with unilateral slipped capital epiphysis (SCFE). Methods: Children who underwent prophylaxis uninvolved hip (Group P) and those were observed no N) presentation SCFE compared. Skeletal was assessed Modified Oxford Score (MOS). Proximal morphology characterized by neck length, width, shaft angle,...

Purpose: Children with cerebral palsy are at a high risk of developing hip dysplasia. Studies have demonstrated substantially improved function early identification and treatment dysplasia through surveillance program regular radiographs. The migration percentage (MP), or the percent femoral head that is outside lateral margin acetabulum on pelvis radiograph, predictive progressive displacement. An MP 30% considered threshold for referral to pediatric orthopaedic center in most programs...

Background: Abnormal hip rotation is a common deviation in children with cerebral palsy (CP). Clinicians typically assess during gait by observing the direction that patella points relative to path of walking, which referred as knee progression angle (KPA). Two kinematic methods for calculating KPA are compared each other. Video-based qualitative assessment quantitative determine reliability and validity. Methods: The was calculated both direct indirect 32 developing (TD) convenience cohort...

Abstract Aim To assess the accuracy, reliability, and discriminatory ability of a mobile app for measurement migration percentage in hip surveillance radiographs children with cerebral palsy (CP). Method The free HipScreen ( www.hipscreen.org ) was utilized by diverse group users to measure 40 hips at two time points after completing an online tutorial competency test. mean absolute error (MAE) calculated against reference standard obtained on radiology workstation. Statistical analyses...

Understanding the pediatric response to polytrauma is essential for orthopaedic surgeon. The physiologic effects of multisystem injury that manifest in a child have important implications coordination treatment, particularly relation timing and incidence organ failure. surgeon plays an role managing hemodynamic instability, vascular insult, neurologic damage with multiple injuries. Indications surgery postoperative immobilization patient differ from those isolated injury. Further research...
