2. Methods of plaster and splinting
ā¢ What is a splint?
ā¢ A splint is a rigid support with padding made from metal, plaster or
plastic. It is used to support, protect,or immobilize an injured or
inflamed part of the body.
The splint is secured in place with an elastic bandage or an ACE wrap
.The purpose of the splint is to prevent movement of the injured
extremity which helps prevent further injury, and to minimize pain
3. Indications for Splinting
ā¢ Fractures
ā¢ Sprains
ā¢ Joint infections
ā¢ Tenosynovitis
ā¢ Acute arthritis /gout
ā¢ Lacerations over joints
ā¢ Puncture wounds and animal
bites of the hands or feet
ā¢ To reduce/prevent contracture
ā¢ To increase grip strength
ā¢ To stabilize and rest joint in
ligamentous injury
ā¢ To correct deformity
ā¢ To support and immobilize joints
and limbs postoperatively until
healing has occured
5. Splinting Materials
ā¢ Plaster Of Paris Bandage
ā¢ First used by Matthysen Dutch military
ā¢ surgeon in year 1858.
Characteristics:
ā¢ ā Plaster of Paris (POP) impregnated
ā¢ bandage.
ā¢ ā Setting time: 4ā5 minutes.
ā¢ ā Full strength of cast is achieved in 24ā48
ā¢ hours
6. ā¢ Chemical reactionāplaster of Paris (calcium sulfate hemihydrate) is obtained by heating gypsum (calcium
sulfate dihydrate). And again when plaster of Paris comes in contact of water, gypsum reappears with release
of some heat (exothermic).
2(CaSO4. 2H2O) + heatā2(CaSO4. 1/2H2O) + 3H2O
2(CaSO4 . 1/2H2O) + 3H2Oā2(CaSO4 .2H2O) + heat
ā Water resistant cast is prepared when melamine resin is mixed with plaster of Paris.
ā¢ Commonly available sizesā4 inch, 6 inch Ć 2.7 meter.
ā¢ Factors affecting setting time:
ā Temperature of water.
ā Manufacturers setting time.
ā Impurities in plaster.
ā Water condition (hard and soft)
ā Humidity.
ā Room temperature.
ā¢ Uses of POP bandage:
ā As a slab for immobilization.
ā¢ Extent of slab coverageā50ā70% circumference (2/3rd) of limb.
ā¢ For upper limbā6ā8 layers and for
lower limbā10ā12 layers
7. ā¢ As definitive casting:
ā¢ Wrapped around whole
circumference of limb or part
involved.
ā¢ The overlapping of bandage is 1/3rdā
1/2 of previous turn.
ā¢ Thickness of cast varies according to
nature of fracture, limb type (upper or
lower) and age of patient.
ā Functional cast bracing.
ā Deformity correction serial casting.
ā Partial weight relieving orthosis.
ā Spica.
ā Charlneyās traction unit.
ā Pin plaster technique.
ā¢ Complications with POP bandage:
ā¢ ā Neurovascular compromise.
ā¢ ā Compartment syndrome.
ā¢ ā Pressure sore.
ā¢ ā Purulent dermatitis.
ā¢ ā Reactionary edema.
ā¢ ā Fracture disease.
ā¢ ā Wasting of limb.
ā¢ ā Joint stiffness.
ā¢ ā Loss of reduction
8. Fiberglass Plaster
ā¢ Characteristics:
ā Composition: Fiber-glass impregnated with
polyurethane polymer.
ā Colorful and sticky.
ā Setting time: 1ā2 minutes.
ā Full strength of cast is achieved in 2ā4 hours.
ā Activated by water or other agents.
ā¢Caution: Surgical gloves must be worn
before using this cast.
ā¢Commonly available sizes 3" and 5" Ć 3.6
meter.
ā¢Advantages: Light weight, water proof, lesser
setting time.
ā¢Disadvantage: Costlier
9. ā¢ STOCKINETTE
ā¢ Characteristics:
āContinuous tubular cotton fabrics.
āWater repellent property.
āStretchable that can accommodate various girth
of limb.
ā¢ Extend it about 10 cm beyond each end of
intended splint site.
ā¢ Commonly available in size 3"(upper limb) and
5"(lower limb) Ć 20 meters.
ā¢Uses: Before application of slab and cast over
limbs.
ā¢Advantages: Prevention from skin complication
like allergy, dermatitis, etc
10. Cotton Roll
ā¢ Properties:
ā 100% cotton and bleached
to white.
ā High absorbent property.
ā Single and uniform lap without joints as thin long
continuous layer.
ā¢ Available in standard 500 g but 100, 200, 300, 400
g also found.
ā¢ Various uses like:
ā For cleaning and swabbing of wounds.
ā For padding before applying slab and cast.
ā For wrapping around splints, etc.
Cotton Roller Bandage
ā¢ Properties:
ā 100% cotton fabrics with a loose open weave and
bleached to white.
ā Quick absorbent property.
ā Number of holes per square centimeter of cotton
gauzeā4 Ć 4 = 16.
ā¢Cotton roller bandages are commonly available in
4" and 6" Ć 4 meters
ā¢Used for:
ā For POP slab application.
ā For wrapping around various splints.
ā During wound dressing.
ā The most common fastening article in ward.
ā¢Starch impregnated roller bandages becomes slimy
when soaked in water and it becomes harder when
dried. This property is utilized to provide
extrastrength to POP slabs.
ā¢Why wet roller bandaging during POP slab
application:
ā Wet bandages increase POP setting time and
provide enough time for plaster molding and limb
manipulation. Wet bandages well incorporated with
slab and provide extrastrength.
ā Dry bandages absorbs water from POP and
decreases the setting time and side by-side it does
not incorporates well with slab
11. Principle Of Reduction and Casting
ā¢ For fracture reduction appropriate amount of traction and countertraction is applied in
proper direction.
ā¢ Reduction is achieved by manipulation of distal fragment.
ā¢ A perfect reduction is said when all cortices are in contact at fracture site or reduction is said
to be acceptable when both fragments have at least 50% contact both in AP and lateral
views.
ā¢ Even minimal rotation at fracture site is hardly accepted.
ā¢ Appropriate padding should be done around fractured limb especially over bony prominence.
ā¢ Reduced position of limb should maintain before, during and after casting.
ā¢ Any indentation during molding and wrinkles should be avoided during cast application.
ā¢ A reduced fracture is maintained in such a way that one joint above and one joint below is
fully immobilized. But exceptions are Collesā fracture, fracture around ankle, etc.
ā¢ The position of limb should be maintained in functional position or position of
immobilization. For most of the joint these two are the same but for wrist and hand these
stands differently.
12. Principle Of Reduction and Casting
ā Functional position: The position in which limb can be maximally utilized even
after its stiffness, e.g. glass holding position of wrist. This position is used for
arthrodesis of a joint.
ā Position of immobilization: The position in which the ligaments and tendons
around joints remains maximally stretched, so that the contracture of joint could
be prevented, e.g. James position of hand (lumbrical plus hand posture).
ā¢ The fracture reduction and maintenance under cast also follows the āthree-point
molding principle of Charnleyāsā. Out of these three points two point lies
proximal and distal to fracture site. The third point lies at the site of fracture site
but the direction of molding force working here is apposite to the above two
points .
ā¢ Ask the patient to follow the instructions like:
ā Keep the limb elevated. Why we ask the patient lying on bed with a cast in his
either of the limb to keep over pillow or hang it with some cord or bandage?
ā¢ Just to maintain the limb above the patient heart level to ensure easy venous
drainage and this act minimizes the swelling.
ā Ask the patient to do finger or toe movementāthis improves the circulation in
the respective limb and side-by-side keep the muscle active and finally minimize
postcast stiffness.
ā Removal of cast is done immediately
ā¢ if any sign of cast tightness develops in the limbālike continuous pain,
discoloration of finger, etc.
