– Discussion: (see IM Nailing of subtrochanteric fractures) – a type of intramedullary device (designed for intertrochanteric and subtrochanteric fractures) which allows controled sliding of the femoral head screw within the IM nail glidign hole; – advantages of IM device: – IM nail with interlocking reconstruction … Read more
origin and insertion: pairs of small muscles joining the spinous process of adjacent vertebrae, one on each side of the interspinalis ligament; continuous in the cervical region extending from the axis to the 2nd thoracic vertebrae and in the lumbar region from the first lumbar vertebrae to the sacrum; action: extension and hyperextension of the spine; nerve … Read more
– Discussion: – frx occur as a result of a fall – from direct and indirect forces; – occurs along lines between greater and less trochanters; – theoretically extracapsular, however, it is not always possible to distinguish betwee intertroch and basilar femoral neck frx; – extracapsular intertroch frx occur thru cancellous bone, which has an … Read more

– Discussion: – major internal rotators are teres major, latissimus, pect major; – latissimus dorsi & teres major insert along medial lip of bicipital groove & pectoralis major along lateral lip and also serve as internal rotators; – these muscles comprise larger mass than those that externally rotate the humerus … Read more
– Discussion: – medial rotation of the tibia at the knee causes an intoeing gait; – it is measured by the angular difference between transmalleolar axis & bicondylar axis of knee; – may result in part to excessive medial ligamentous tightness; – it is associated with metatarsus … Read more
– The Problem: – External fixation is perceived as an inferior treatment method for management of tibia fractures even though there is scant evidence to support this in prospective studies. – in the JTO 2000 special report by Seligson, et al, the authors conducted an international survey of treatment methods for tibia … Read more
– Discussion: – almost completely bridges radius & ulna from proximal to distal R-U joint – acts as a hinge for rotation of radius about ulna; – fibers run distally in oblique direction from radius and ulna; – central portion thickened in 3.5 cm band; … Read more
