So now what we are going to have a look at is lower limb Immobilization. We use this technique if we got a potential fracture, dislocation or damage to a lower limb itself. Anything below the pelvis down, down to the knee, right down to the tip of the toe. What we are going to do is we normally have one good leg, one bad leg, if we move the limbs we have to move the good limb to the bad limb because we want to move the bad limb as little as possible and the whole idea about this technique is to give stability to the bad leg. We are going to need three things, we are going to need three triangular dressings, we are potentially going to need something to give us some support for the hollows between the legs themselves, and another little tip is to have an extra rubber glove available because that will come useful and you will see how that's used in a moment.

So, the points we immobilize. We need to take out the flexible joint, so we need to put one triangular bandage above the knee, taking out the neck of femur and the femur itself and stabilizing that with a pelvis. We then need to go below the knee, stabilizing the tib and fib and the patellar itself, and the final one is a figure of eight around the feet to stabilize the feet and keep the feet together. Basically, we are splinting the poor leg against the good leg. So, if we imagine for this scenario that the left leg is the leg that is injured, we are going to bring the right leg to the left leg. When the feet are together you will notice there is a gap between the two legs, everybody will be different but where you got a large gap or a reasonable gap it's quite often good to pack that with a rolled blanket, a jumper, anything that will give it some support, and some stability between the two knees. We don't want the flex in when we tighten the bandages up. So the next thing we're going to do that will make this a lot easier, is we're going to control the two feet. Now, normally we will control the two feet and keep them together with the knees and then comes the rubber glove trick. If you take a rubber glove, a spare rubber glove, open the glove and pop it over the toes, it supports the legs, keeps the feet together while we do the strapping.

So, then we are going to get the triangular bandage and we are going to roll the triangular bandage up to form a strap or a tie-off point. We are going to use the hollows, under the knee, under the ankles, and then we will feed up or down. So if we go at the back of the knee and feed the actual support underneath and go above the knee. We take the second triangular bandage, repeat the process, under the knee again... And come below the knees and then we take the final triangular bandage. Again, roll it up, go onto the heels and feed underneath the back of the ankles. So the first one we're going to apply is the figure of eight around the feet itself. We cross and put a loop, and tie. That brings the ankles together, we then take the loop around the base of the feet and tie-off at the bottom of the feet. That keeps the feet together, keeps the legs together and gives you some stability in the lower limb area.

Remember though, we can't tie-off and should never put the strapping over where the fracture site or the damaged site is. If we got fractured ankles, we wouldn't use this, we would just use around the feet or use the rubber glove on its own. Again, with the mid shaft, tib and fib or femur fractures, we need to make sure we are not tying off over the fracture site. We then come across, again, supporting below the knees and tying off and above the knees, tying off. And what we now created is a fixed point for the fracture. Stabilising it, allowing us now to move the patient without disturbing, moving, flexing or doing any more damage to the injury site itself. Above, below the knee figure of eight around the feet, packing them between the two and the rubber glove at this point can either be taken off or left in situ because the feet are now fixed with a figure of eight, around the feet themselves. Lower limb immobilization.
