INTRODUCTION The end of medial opening oblique wedge high tibial osteotomy (HTO) points into a narrow area between the articular cartilage of the posterolateral proximal tibia and proximal tibiofibular joint (PTFJ) at the tibial site, which is an anatomical safe zone (ASZ) for osteotomy. We studied the ASZ and its relation to the fibular tip, including the level of posterior cruciate ligament (...

Objective(s) Quinazolinones are heterocyclic compounds, with biological and pharmacological activities, such as inhibiting some proteins, enzymes and reducing blood lipids. Materials and Methods Following previous results of our group, effects of two new derivatives of quinazolinones 9(3)-quinazolinone-2-propyl-2-phenylethyl (QPPE) and 9(3)-quinazolinone-2-ethyl-2-phenylethyl (QEPE) on liver...

The accelerated proximal gradient (APG) method, first proposed by Nesterov for minimizing smooth convex functions, later extended by Beck and Teboulle to composite convex objective functions, and studied in a unifying manner by Tseng, has proven to be highly efficient in solving some classes of large scale structured convex optimization (possibly nonsmooth) problems, including nuclear norm mini...

We present results of supracondylar nailing in six patients who suffered distal femoral fractures above total knee arthroplasty. The average age of patients was 68 (42-92) years. All six fractures healed in a satisfactory alignment in an average duration of 14.6 weeks. There were no wound infection, loss of reduction or implant failure. All patients had regained their previous range of movement...

In this paper, we discuss the problem of minimizing the sum of two convex functions: a smooth function plus a non-smooth function. Further, the smooth part can be expressed by the average of a large number of smooth component functions, and the non-smooth part is equipped with a simple proximal mapping. We propose a proximal stochastic second-order method, which is efficient and scalable. It in...

OBJECTIVE to assess the surgical technique using the modified palm open technique for the treatment of severe contractions of Dupuytren's disease. METHODS over a period of four years, 16 patients underwent surgical treatment, and in its entirety belonged to stages III and IV of the classification proposed by Tubiana et al. We performed measurements of the extension deficit of the metacarpopha...

OBJECTIVE This study was designed to describe the anatomic insertion point of the deltoid to the proximal humerus. DESIGN Gross anatomic study. SETTING Level one academic trauma center. PATIENTS Cadaveric study. MAIN OUTCOME MEASUREMENTS Bilateral humeri were stripped of soft tissue except the deltoid insertion point. The length of the humeri was recorded. The distance from the greater ...

PURPOSE Good results of the cephalomedullary nails have been reported in proximal femoral fractures recently. Based on length of nails and shape of screws fixed in a femoral head for proximal fragment fixation, the proper nail length was in dispute. The purpose of this study was to evaluate the clinical and radiological results of a long cephalomedullary hip nail for the treatment of comminuted...

BACKGROUND The purpose of this study was to investigate the feasibility of single-breath-hold whole-heart MRA with a 3-T system. Ten healthy male volunteers underwent single-breath-hold whole-heart coronary MRA at 3 T. We assessed acquisition time, scores of image quality of coronary artery (RCA: proximal, middle and distal, LAD: main, proximal, middle and distal, LCX: proximal and distal) and ...
