For the Siemens Siremobil Compact it should always be all the way back in its travel range to allow for maximum forward travel to reduce lateral magnification. Place the guidepin. There is little in the literature regarding the management of intertrochanteric hip fractures in patients with ipsilateral above or below knee amputations. With an annual budget of roughly $11.5 billion, the Department of Health Services (DHS) is one of the largest and most diverse state departments in Wisconsin. Securing the amputated limb to the fracture table poses a significant challenge. Its angle can vary from 135° to 150° and can be located at a corresponding distance of 2.5 cm to about 6 cm from the innominate tubercle. Surgery is the most common treatment for a hip fracture, although there are some situations when surgery isn’t advised. We describe a positioning technique used on a 51-year old patient with a right above knee amputation who sustained an intertrochanteric extr-capsular hip fracture. The skin around the stump needs to be carefully inspected prior to application of this technique as any fragile areas may become prone to breaking down during the procedure if prolonged.

Don’t move your foot until the machine has stopped and then quickly apply the brake. The DHS plates have a low-profile design, reducing the risk of trochanteric bursitis. To adjust from side to side use the ‘Pan’ rotation lock instead. When the next image is taken the acetabulum will be shown at the top of the image as required. [4] described inverting the boot to fit around the knee and stump in a below knee amputee to facilitate positioning the application of traction if necessary. The positioning of patients with amputations either above or below knee of the affected side can pose a significant challenge. Hand Surgery Theatre Radiography Technique /////. The best way to use it is in conjunction with a simple laser cross projector. Combining a specially formulated porous adhesive and a superior woven cloth, Elastoplast now Tensoplast, provided satisfactory adhesion while remaining secure in place. Due to the size of the stump and the small area the skin traction is applied to, it cannot generate any significant amount of traction prior to it getting unravelled. There is a standard setup which is commonly used with relative ease. Our setup involved the standard fracture table used routinely to position a patient for DHS fixation.
