AIM The aim of this study was to assess accuracy of echocardiography in the measurement of left ventricular ejection fraction (LVEF), enddiastolic volume (EDV) and endsystolic volume (ESV) compared with gated SPECT. METHODS A total of 70 patients with left ventricular systolic dysfunction were enrolled to study. Median of the time interval between gated SPECT and echocardiography was 1 hour. ...

Abstract Background Medial open-wedge high tibial osteotomy (HTO) is an effective and safe treatment method for medial osteoarthritis of the knee. However, unintended changes in posterior slope (PTS) may occur. Several factors cause PTS alterations after HTO; however, research on sagittal-plane inclination (SPOI) relation to sparse. The purpose this study was evaluate whether SPOI affects HTO. ...

To prevent patella infera in open wedge high tibial osteotomy, a new operation technique was developed. Instead of a proximal tibial tuberosity osteotomy, a distal osteotomy was performed and the tuberosity was fixed with one screw to the tibia. Initial experience in 17 patients was evaluated and compared with results of 20 patients with open wedge high tibial osteotomy with proximal tuberosity...

background: legg-calve´-perthes disease is a juvenile idiopathic osteonecrosis in which the blood supply of femoral head is not sufficient and the bone dies provisionally. the aim of this study is to evaluate outcome of femoral osteotomy in children with lcpd in our university hospital.   methods: in a descriptive analytic study, between 2008 and 2013, patients with the diagnosis of legg-calve’...

INTRODUCTION: Hallux valgus (bunions) are prominent and often inflamed metatarsal heads and overlying bursae. They are associated with valgus deviation of the great toe which moves towards the second toe. Hallux valgus is found in at least 2% of children aged 9 to 10 years, and almost half of adults, with greater prevalence in women. METHODS AND OUTCOMES: We conducted a systematic review and ai...

IMPORTANCE The different nasal osteotomy patterns used to perform rhinoplasty are poorly described in the literature, and there is a continuous debate between surgeons on the ideal sequence and technique to obtain desired results. OBJECTIVES (1) To evaluate the necessity of a paramedian osteotomy when performing a high-low-high (HLH) osteotomy, (2) to study the fracture pattern of a high-low-...

In this paper, we present a new method for the 3D reconstruction and visualization of coronary arteries in biplane angiography. The proposed method performs direct reconstruction of 3D coronary artery pathways without computing the 2D or 3D vessel centerlines. A front propagation algorithm is used to reconstruct the coronary artery pathways in 3D space. Starting from one or more 3D points, the ...
