PURPOSE Among patients over 50 years of age, separate vertical wiring alone may be insufficient for fixation of fractures of the inferior pole of the patella. Therefore, mechanical and clinical studies were performed in patients over the age of 50 to test the strength of augmentation of separate vertical wiring with cerclage wire (i.e., combined technique).(More)
Pseudoaneurysm arising from the superficial temporal artery (STA) is very rare and is most commonly caused by blunt trauma. Most pseudoaneurysms of the STA usually present as a painless pulsating mass, with concomitant symptoms according to location, and their size may rapidly increase. The treatment of choice is ligation and resection. We present a case of(More)
To investigate the effects of sulfur dioxide (SO2) on olfactory epithelium, an experiment was performed with 56 mice from the same colony. Experimental animals were divided into three groups consisting of a 30-min exposure group (group 1), a 60-min exposure group (group 2), and a 120-min exposure group (group 3). The olfactory mucosa in these mice were(More)
− − − −An experimental study was performed for the recovery of CO 2 from flue gas of the electric power plant by pressure swing adsorption process. Activated carbon was used as an adsorbent. The equilibrium adsorption iso-therms of pure component and breakthrough curves of their mixture (CO 2 : N 2 : O 2 =17 : 79 : 4 vol%) were measured. Pressure(More)
OBJECTIVES This study aimed to identify the clinical implications of valgus-impacted femoral neck fractures and compare fractures with >15-degree angle of impaction (31-B1.1) against fractures with <15-degree angle of impaction (31-B1.2). DESIGN Retrospective study. PATIENTS/PARTICIPANTS We enrolled 78 patients with 31-B1 femoral neck fractures who were(More)
The major meniscal functions are load bearing, load distribution, and shock absorption by increasing the tibiofemoral joint (TFJ) contact area and dissipating axial loads by conversion into hoop stresses. The increased hoop strain stretches the meniscus in outward direction towards radius, causing extrusion, which is associated with the root tear and(More)
Clinicians frequently diagnose chronic ankle instability using the manual anterior drawer test and stress radiography. However, both examinations can yield incorrect results and do not reveal the extent of ankle instability. Stress ultrasound has been reported to be a new diagnostic tool for the diagnosis of chronic ankle instability. The purpose of this(More)
INTRODUCTION The aim of our study was to identify the risk factors for avascular necrosis of the femoral head (AVN) and fixation failure (FF) after screw osteosynthesis in patients with valgus angulated femoral neck fractures. PATIENTS AND METHODS We conducted a retrospective study of 308 patients (mean age, 72.5 years, range, 50-97 years), with a mean(More)
RATIONALE Pycnodysostosis is a rare autosomal recessive skeletal dysplasia characterized by short stature, craniofacial dysmorphism, acro-osteolysis, osteosclerosis, and brittle bone with poor healing. Pycnodysostosis results from the deficient activity of cathepsin K, a lysosomal cysteine protease that is encoded by CTSK. PATIENT CONCERNS We report a(More)
