SAM Splints are one of the simplest and most versatile pieces of first aid equipment available so at least one should be in every outdoor First Aid kit. A soft, malleable aluminium strip sandwiched in foam, the splints become fairly rigid once formed into a 3D shape, the more complex the shape, the more rigid they become.
They are by no means the gold-standard in immobilisation but given their small size, light weight, ease of use, reusability, are unaffected by water, heat, dirt, have no moving parts, can be cut with shears and are radiolucent, for under £12 their value cannot really be matched by anything else.
But as with all equipment, the value is not in owning them, it is in knowing how to use them effectively:
· When moulding the Splint, mould it around someone of a similar size and build as the casualty. DO NOT mould the splint around the casualty's injury!
· A Splint can be made more comfortable by padding it once formed or inserting it into a thick sock. This is especially important for long term use.
· The Splint can be held in place with anything from torn t-shirts to tape. Elasticated bandages, cohesive bandages and cling film provide greater stability and more even pressure along the limb. Cling film has been used in these photos for clarity and is our preferred choice but caution should be use with both cling film and cohesive bandages; because of their resistance to stretch it is very easy to apply them too tightly.
· Always check Colour, Sensation and Movement (CSM) of the extremities of the injured limb before and after applying the splint and regularly thereafter. Be prepared to remove the Splint as soon as there is a loss or reduction in one of these functions.
· Splinting an injury is not time-critical so take your time. Prototype your splint on someone else before attempting to apply it to the casualty. Find out what works and what doesn't work. The casualty will not appreciate you making mistakes on them.
· There are only three criteria to effective immobilisation: it must immobilise, be comfortable and not affect circulation.
This is the most common uses of the Splint; it is effective and easy to apply.
Pinch the end at the elbow.
Once formed, apply padding or insert the splint into a sock.
Secure the splint; start wrapping at the wrist, work up to the elbow then back down again but this time to the knuckles.
Ankle Injury - Weight-bearing
A weight-bearing ankle injury can be supported inside the boot or shoe to allow the casualty to remain mobile.
SAM recommend supporting the ankle as a 'stirrup' under the heal; this does not reduce flexion or extension of the foot.
Remove the insole of the footwear and place it between the foot and the splint.
Wrap and support one half of the splint up and across the shin before doing the same with the other side.
The immobilised ankle can be placed into the footwear - the lacing pattern will have to be adjusted to accommodate the extra bulk.
Where the ankle injury is not weight-bearing or if is not possible to remove the footwear in the case of an unstable ankle injury or simply too painful, the ankle is immobilised within the footwear.
The splint is applied in the same way as above but the strapping starts at the ankle, up the lower leg and back down to the ankle, finished with a figure of eights around the ankle and instep.
Knee Injury - Straight Leg
To properly support a knee injury in an extended position you will need two Splints.
Fold each splint into a narrow "V" and tape into position.
Fold a pronounced curve along the whole length of each structure.
Position each structure either side of the leg, centralised at the knee.
Knee Injury - Bent Leg
Using either two splints or one cut in half, fold a pronounced curve along the length of each piece.
Pad each piece before applying each side of the knee leaving enough above the knee to fold over the thigh.
Wrap the splints in place from the lower edge up to just below the knee cap.
Fold one piece over the top of the knee. Wrap the upper section in place,
Fold the other piece over the top of the previous one and wrap similarly.
