What is a dynamic hip screw?
Dynamic hip screw is a device used to repair a broken hip. One half of the hip consists of a rounded piece of bone, called a femoral head, supported by a narrow femoral neck at the top of the femur or thigh bone. This rounded head sits inside the cavity called acetabul, located in the hip bone, where it rotates smoothly, leading to the entire range of normal hip movement. Sometimes injuries, such as the fall of the femoral neck, can then need to be fastened, while the bones heal using a device such as a dynamic hip screw. The advantage of using a dynamic hip screw is that it allows patients to walk soon after surgery, avoid long -term rest in bed and related risks of chest infections and blood clots in the legs.
Operations to repair a broken hip is a type of orthopedic surgery. Orthopedic surgery involves treatment of problems including skeleton and its attached muscles. When an orthopedic implant like dynamic hipThe screwed, technique is sometimes referred to as fixation of the sliding screw.
The procedure of the dynamic hip screw may require a hospital stay for several days. Surgery is usually performed under a general anesthetic, so that the patient sleeps during operation and no food or drink can be used in hours leading to the procedure. Occasionally, an anesthetic may be given that the numb body under the waist.
During the surgery, the dynamic hip screw is inserted into the femur. It consists of a large screw, which is fastened to the femoral head at an angle, connected to the metal plate, which is vertically located along the femur shaft and attached in a place with smaller screws. The surgeon uses X -ray images to ensure the accurate placement of the dynamic hip screw.
After surgery it is usually possible to eat and drink normally later on the same day. Dripping will be cooked on the vein in the arm and this is usually removedEven a tube that releases the wound can be left in place a little longer. Painkillers are administered to release any discomfort.
After a day of rest in bed, patients are invited to walk using walking. The dynamic hip screw design means that it is possible for a broken hip to carry while healing. Mobile maintenance helps to reduce the risk of blood clots that occur in the feet, and reduces the chance of ulcers associated with lying in bed. Moving also helps to stimulate breathing, so it is less likely to develop chest infection. Once patients walk independently and safely, it is usually possible to return home.
