Clavicle fractures are common injuries in young, active individuals. The majority of the fractures (80% to 85%) occur in the mid-shaft of the bone and account for approximately 2.6% of all fractures. For many years the standard treatment of fracture clavicle was the "figure-of-eight" bandage but several indications for operative fixation, the position of plate fixation for clavicle fracture remains controversial. The aim of this study is to compare between anterio—inferior and anterior-superior plating of mid-shaft displaced clavicle fracture in complications, plate prominence, nonunion, malunion and range of motion. This study is a prospective study conducted in Al-Kindy teaching hospital .A total of 30 patients with fracture mid –shaft clavicle were selected non-randomly and were randomized digitally into two groups (First group fifteen patients with mid-shaft clavicle fracture fixed with anterio-superior plating. The second group also fifteen with mid-shaft clavicle fracture fixed with anterio-inferior plating). Anterio-superior plating have 13.3% nonunion, 13.3% surgical site numbness and 40% plate prominence while anterio-inferior plating have 26.7%, 33.3 %, and 20% respectively. Our conclusions are both methods are used for fixation of the middle third of clavicle displaced fracture in the adult but anterio-superior plate associated with better result regarding union time, numbness and DASH (disabilities of arm ,shoulder and hand) score

In this article four samples of HgBa2Ca2Cu2.4Ag0.6O8+δ were prepared and irradiated with different doses of gamma radiation 6, 8 and 10 Mrad. The effects of gamma irradiation on structure of HgBa2Ca2Cu2.4Ag0.6O8+δ samples were characterized using X-ray diffraction. It was concluded that there effect on structure by gamma irradiation. Scherrer, crystallization, and Williamson equations were applied based on the X-ray diffraction diagram and for all gamma doses, to calculate crystal size, strain, and degree of crystallinity. I
