2          Closed fractures - break in the bone which has not yet penetrated the soft tissue

a0         May not be as obvious, yet serious potential for other injuries

3          Comminuted fractures - a break which involves several breaks in the bone causing bone fragment damage; consider the combined blood loss and potential for other injuries

4          Greenstick fractures - a bone break in which the bone is bent but only broken on the outside of the bend; children are most likely to have these

5          Spiral fracture - a bone break caused by a twisting motion

6          Oblique fracture - a bone break at a slanting angle across the bone

7          Transverse fracture - a broken bone that occurs at right angles to the long part of the bone involved

8          Dislocations - a bone moved from its normal position at a joint and may have associated fractures

9          Sprains - an injury to the tendons, muscles or ligaments around a joint, marked by pain, swelling, and dislocation of the skin over the joint

10         Strains - damage, usually muscular, that results from excessive physical effort


11         Joint injury - may be a fracture, dislocation or sprain

IV         Management

A0        General principles

1          Splint joint above and below as well as bone ends

2          Immobilize open and closed fracture the same

3          Cover open fracture to minimize contamination

4          Check pulses, sensation, and motor function before and after splinting

5          Stabilize with gentle in-line traction to position of normal alignment

6          Immobilize where they are found not in the exact position the limb is found

a0         It makes most sense to move a long bone injury into a “splintable” straight position

b0         Joint injuries are only moved if there is no distal pulse

7          Immobilize dislocation/ fractures in position of comfort and good vascular supply


8          Immobilize joints as found

9          Application of cold

a0         Reduce swelling

b0         Reduce pain

10         Compression

11         Elevation of extremities

B0        Splints - rigid, formable, traction

b0         Principle

c0         Types

8          Long spinal immobilization devices

a0         Ultimate body splint

b0         Refer to spinal injury section

C0        Dislocation/ fractures

1          Realignment

a0         Typically dislocated joints should be immobilized in the position of injury and transported for reduction

b0         Delayed or prolonged transport requires a different approach

c0         An attempt to reposition any dislocated joint into anatomical position should be made if distal circulation is impaired and if transportation is long or prolonged

d0         Check circulation and nerve function before and after any manipulation of any injured bone or joint

e0         Discontinue an attempt at repositioning if

(1)        Pain is increased significantly by manipulation, and/ or

(2)        Resistance to movement is encountered

2          Limb-threatening injuries

a0         Knee dislocation/ fracture

b0         Dislocation/ fracture of the ankle

c0         Subcondular fractures of the elbow

(5)        Procedure

(a)        Traction

(b)        Hip 90 degrees

(c)        Knee 90 degrees

(h)        Immobilization, comfortable flexion not to exceed 90 degrees, pillows, chair, cardboard, supine position of patient

c0         Knee realignment - do not confuse with a patella dislocation, this is a limb-threatening injury

(1)        One attempt if there is severe neurovascular compromise

(2)        As soon as possible after the injury

(3)        An attempt to reposition a dislocation of the knee into anatomical position should be made if transport time is delayed or prolonged greater than two hours, even if distal circulation is normal

(4)        Do not attempt if associated with other severe injuries

(5)        Analgesics

(6)        Procedure

(a         Pull traction in the anatomical position only

D.         Specific fracture pointers and immobilization techniques

(1         Direct manual stabilization of the injured leg

(2         Assess distal motor ability, sensory response, and circulation

(3         Rule out any contraindication to traction splinting

(4         Direct application of manual traction if elevating the leg from the ground

(5         Adjust and position splint at the injured leg

(6         Apply proximal securing device (e.g., ischial strap)

(7         Apply distal securing device (e.g., ankle hitch)

(8         Apply mechanical traction

(9         Position and secure support straps

(10        Re-evaluate the proximal/ distal circulation

(11        Reassess distal motor ability, sensory response, and circulation

(12        Secure patient’s torso and traction splint to long backboard for transport

b.         PASG and long backboard

c.         Long backboard and long board splints

d.         Opposite extremity and long backboard

e.         Fractures of the proximal femur present similar to the anterior hip dislocation

f.          Midshaft or distal femur fractures can have soft tissue, vascular and nerve damage

3.         Tibia/ fibula

a.         Pneumatic splint

b.         Long board splint procedure

(1         Take body substance isolation

(2         Direct application of manual stabilization

(3         Assess distal motor ability, sensory response, and circulation

(4         Measure splint

(5         Apply splint

(6         Immobilize joints above and below the injury site

(7         Secure the entire injured extremity in a distal to proximal direction

(8         Immobilize hand/ foot in the position of function

(9         Reassess distal motor ability, sensory response, and circulation

c.         Splinting to the opposite leg

d.         Cardboard

4.         Ankle - same as tibia/ fibula fractures, generally involves the distal tibia and fibula

a.         Pillow splint and leg immobilization

b.         Air splint

5.         Foot

a.         Pneumatic

b.         Cardboard


c.         Ladder splint

6.         Shoulder dislocation/ fracture

a.         Anterior - arm close to the chest and hollow shoulder

b.         Posterior - arm may be over the head

c.         Splinting - be creative, improvise to hold the injury in place (e.g., blanket roll)

(1         Use a rolled blanket with a cravat through the center

(2         Position the roll under the elevated arm and secure it like a sling with the cravat through the blanket

(3         Swathe the arm to prevent upward movement

(4         If the arm is over the head - splint in position, or pull traction along the long axis of the arm

7.         Knee

a.         High incidence of vascular and nerve damage

b.         Any fracture within three inches of a joint should be treated similar to a dislocation

c.         Use triangulation with cravats and two long padded splints

d.         SAM splints are not strong enough for the knee while some ladder splints if properly padded will be effective with immobilization of the hip and ankle

e.         Do not use a traction splint

f.          If found straight use two board splints or cardboard splint

8.         Humerus

a.         Difficult to stabilize

b.         Potential for severe circulatory problems

c.         If the patient has a potential neck injury do not tie a sling around the neck

d.         Use a sling and swathe  with splints surrounding the humerus or splint with the extremity extended

9.         Elbow

a.         High probability for blood vessel and nerve damage

b.         Especially dangerous in children (supracondylar fractures)

c.         Volkman’s contracture may result

d.         Padded wire splint and sling and swathe

10.        Forearm fracture

a.         May involve radius, ulna, or both

b.         Colle’s fracture of the wrist presents with the wrist in a “silver fork” position

c.         Splint like a lower leg fracture described above

11.        Hand and wrist fractures

a.         Common with direct trauma

b.         Noticeable deformity

c.         Significant pain

d.         High incidence for nerve and vessel damage

e.         Splint on a padded board splint with the hand in position of function

12.        Epiphyseal fractures

a.         Weakest part a child’s joint

b.         Presents as a sprain in an adult

c.         May result in a permanent angulation or deformed extremities

d.         May cause premature arthritis

E.         Application of cold/ heat

1.         Cold in the first 48 hours to reduce swelling

2.         Heat after 48 hour to increase circulation


F.         Referral of minor musculoskeletal injuries

1.         Evaluate the need for immobilization

2.         Evaluate the need for an x-ray

3.         Evaluate the need for a physician follow-up visit versus ED visit

4.         Contact medical control for advisement
