The Skeleton
 Provides
structure and protection
 Axial skeleton – skull, vertebrae, and
thoracic cage
◦ Transfer weight from upper to lower
body
◦ Responsible for upright position
skeleton – shoulder,
arm, pelvis, legs
 Appendicular
◦ Responsible for movement

The Skeleton
 Types
of Bones
◦ Long: Humerus, radius, ulna, femur,
tibia, fibula
• Breaks at epiphyseal line (growth plate) can
be serious for growing children
◦ Flat: Skull, scapula, ribs, sternum, pelvis
◦ Irregular: Vertebrae, wrist, hands, ankle,
feet, patella

Joints
 Joint:
Two bones and the connective
tissues that surround, support, and
stabilize it called the joint capsule.
Synovial fluid in the joint capsule
lubricates joints.

Joints
 Range/type
of motion depends on
type of joint:
◦

Ball and socket: shoulder, hip.
Hinge: knee, finger.
Gliding: wrist, ankle.
Pivot: base of thumb.
Suture: pelvis, skull.

Ligaments and Tendons
 Ligaments
connect bone to bone,
form part of joint capsule
◦ Restrict the motion of the joint
◦ Tightness/laxity help determine extent of
movement
 Tendons
connect muscle to bone
 Both can be stretched or torn
◦ Stability and function suffer

Muscles
contracts and relaxes – often
work in pairs
 Controlled by nervous system – spinal
and peripheral
 Three types:
 Tissue
◦ Skeletal (voluntary)
◦ Smooth
◦ Cardiac

Physiology of Movement
 Skeletal
muscle message is
“contract”
◦ Signal provided by nerves
◦ May be voluntary or involuntary
◦ Pairs work in coordination to flex and
extend joints

The Healing Process
 Factors
are extent of damage, age,
nutrition, overall health
 Bone healing requires nutrients,
oxygen, and immobilization
 Muscles and ligaments heal slowly
 Tendons need protection during
healing
 Cartilage does not heal, it is often
removed

Common
Musculoskeletal Injuries
 Sprain
◦ Stretching or tearing of a ligament
• Tears may need surgery
◦ Joint is displaced beyond its normal
alignment

Common
Musculoskeletal Injuries
 Strain
◦ Stretched or torn muscle
• Overexertion or poor body mechanics
• May range from minor to severe
◦ Strain versus Sprain
• You strain a muscle or tendon and sprain a
ligament.

Break in a bone
May be open or closed
May be displaced or non-displaced
May be associated with internal or
external bleeding

Common
Musculoskeletal Injuries
 Dislocation
◦ Separation or displacement of bones at
a joint
◦ Usually the result of forceful trauma
 Multiple
structures and surrounding
tissues may be injured in a single
event
◦ Soft tissues, nerves, and blood vessels
may be involved

Fractures
 Pelvis
(1300-1500 ml)
 Femur (500-1000ml)
 Humerus (300-500ml)

posterior reference points –
head, shoulders, hips
 Three
◦ The goal is to keep them aligned and in
the same plane during moves
◦ They are secured in all moves (legs too
if 4th rescuer is on scene)

moves are axial or vertical – never
sideways
 Movements are made in short
increments
 If straightening of head, neck, or limbs
is needed, do only one at a time
 All
◦ Begin with head/neck (for airway)
◦ Stop for major pain or resistance
 End

Management
 Deal
with life threats
 General care has common steps
◦ Use BSI
◦ Plan of action to include help,
equipment, and transport needed
◦ Expose injury to observe for bleeding,
deformity, discoloration, swelling
◦ Control bleeding, bandage wounds

Management
 General
care has common steps
◦ Immobilize as needed – check CMS
◦ Ice for swelling
◦ Transport to aid room, monitor patient
comfort
◦ Reassess for CMS and bleeding, adjust
treatment as needed
◦ O2 as needed
◦ Transfer to higher level of care

Assessment
assessment procedures –
ABCDs, SAMPLE, and vitals
 Standard
◦ Determine number of patients
◦ Use MOI to point to possible injuries
◦ Look for guarding

Assessment
 Thorough
physical exam – DCAP-
BTLS
◦ Pain/point
tenderness,
deformity,
swelling are
common signs
and symptoms
◦ Evaluate each
side separately

Assessment
 Note
CMS distal to injury
 Palpate injured area last
 Expose injury site
◦ On scene to control bleeding
◦ In aid room to shield from weather, for
modesty
 Formulate
management plan
 Reassess vitals/CMS

Bruising, wounds, skin “gaps” or “tents”
Decreased motion

Upper Extremity Injuries
 Falling
onto outstretched hand, elbow,
shoulder may cause these
 Assess from scapula to fingertips

Clavicle - AC joint
Shoulder
Humerus – elbow joint
Radius/ulna – wrist joint
Hand, fingers, joints

Upper Extremity Injuries
 Clavicle
is frequently fractured
 Sternoclavicular (SC) joint dislocation
(posterior) may be life threatening
 Shoulder (AC) separation / dislocation
differ in character and severity
◦ Anterior dislocations more common
 Scapula
fractures require severe MOI
continued
 Humerus fractures may result in
nerve damage

Upper Extremity Injuries
 Detecting
Injury Type
◦ Patients with A/C injuries, clavicle fractures,
scapular fractures, and humeral head and neck
fractures generally hold their arm against their
abdomen; patients with posterior shoulder
dislocations hold their arm against their abdomen
and will not let you bring the arm away from the
abdomen (external rotation). By contrast, patients
with anterior dislocated shoulders hold their arm
out and up. Thus the position in which a patient
holds the injured arm can help you identify the
continued
possible injury.

Upper Extremity Injuries
fractures involve bones –
dislocations lock joints, CMS issues
 Radius and/or ulna may fracture
 Wrist fracture may involve distal
radius/ulna (Colles) or carpal bones
 Skier’s thumb common ligament
injury
 Elbow

Lower Extremity Injuries

Assess from pelvis to toes
◦
◦
◦
◦
Hip joint – femur
Knee joint
Tibia/fibula – ankle joint
Foot , toes, joints
Femur connects to pelvis at hip joint – may
dislocate and/or fracture
 Femur fractures involve high energy
continued
trauma

Lower Extremity Injuries
 Knee
ligament/cartilage injuries are
common
◦ True dislocation is an emergency
 Patellas
may fracture or dislocate
 Tib and/or fib may fracture
 Ankle may sprain, fracture, dislocate
◦ Location gives clue to injury type
 Foot

injury takes many forms

Splinting
 Splint
to:
◦ Prevent further tissue damage
◦ Allow easier transport
◦ Prevent paralysis in spinal injuries
BRADY

Principles of Splinting
 Splint
before moving patient
 Check CMS before and after
 Manually stabilize injured area
 Use correct type/size, pad as needed
 Position, move limb carefully, and
secure
 If shock is significant, work quickly
continued
and transport

Principles of Splinting
 If
deformity is present with fracture,
align if possible
 If alignment is not possible, secure in
best position for stability/comfort

Principles of Splinting
 Do
not attempt to reduce fractures or
force bone ends back into skin
 Remove jewelry before swelling
occurs – account for it
 Immobilize above and below injury
site (bones for joint injury, joints for
bone injury)
 Advise patient to seek follow-up care

Quick Splint Replacement
 Many
quick splinted injuries are
repackaged in the first aid area
 Consider not replacing a quick splint if
there are:

Serious multiple injuries
Very unstable fractures
Bandaged open fractures
Fractures accompanied by advancing
shock

Chapter Summary
 The
most frequent injury in skiing is a
knee sprain.
 The most frequent injury while
snowboarding is a distal radius
fracture.
 A common upper extremity injury
among skiers is skier’s thumb.

Chapter Summary
 The
clavicle is the most commonly
broken bone in the body.
 For extremity injuries, remove all
rings, bracelets, or other jewelry from
the hand or foot immediately, before
swelling occurs.
 Treat all threats to life first, and then
manage musculoskeletal injuries.
