5 Function of Musculoskeletal System Gives body its shape Protects internal organs Can also cause injuries to those same organs Allows for movement Usually performed by muscles Storage system for salts and
minerals used in the body Produces red blood cells used for oxygen transport 6 Control of Musculoskeletal System Under control of the brain and nervous system Skeletal muscle is voluntary muscle Can be contracted and relaxed at the will of the individual
Walking, sitting Swallowing, smiling Talking Performing activities of daily living 7 A & P Musculoskeletal System A bony framework making up the skeleton System held together by ligaments
Ligaments connect bone to bone System held together by layers of muscles Tendons connect muscles to bones Skeletal muscles are voluntary Includes additional connective tissue Example: cartilage 8 Joints May be movable or immovable
Movement direction includes Flexion Extension Abduction Adduction Pronation
Supination 9 Pathological Fractures Fractures resulting from a disease that causes degeneration and weakening of a bone making it prone to fracture Fracture often occurs with little provocation; minimal force Often occurs in the presence of a diagnosis of cancer 10
Effects of Aging Decreased flexibility Decreased range of motion Loss of balance Osteopenia loss of bone mineral density; softening of bones Osteoporosis degenerative bone disorder with loss of bone density making bones brittle and fragile Weakened bones more susceptible to fracturing More common in women than men but affects
both populations 11 Counteracting the Effects of Aging Stay active Strengthen your core Helps with balance Continue weight bearing exercises Cardiovascular exercise strengthens your heart Strength training builds bone and
muscle strength 12 Mechanism of Injury Determining mechanism of injury can help determine area of injury and may point to the extent of injury suffered Forces divided based on MOI Direct a direct blow i.e.: knees hit dashboard in MVC injuring the knee Indirect force impacts one end of limb and damage transmitted to a distant point
i.e.: fall on outstretched arm resulting in fractures of the wrist and clavicle Twisting one part of extremity stationary while the rest twists i.e.: sliding on ice, at end of ice patch the foot stops but 13 the body remains in motion and rolls over the foot Can you tell what the injury is??? No, not always without more diagnostics Most musculoskeletal injuries are treated the same regardless of the final diagnosis
So Why do you need to know the difference between a sprain and a dislocation or fracture??? Because As a professional, you should be able to use critical thinking skills You might be able to fine tune treatment based on mechanism of injury and your impression 14 Strains
Injury to a muscle or muscle and tendon Often caused by overextension or over stretching Muscle fibers tear Pain is typical to that experienced from over muscle use Often no swelling or discoloration because there is no bleeding 15 Sprains Injury to the joint capsule with
damage to or tearing of the connective tissue Usually involves ligaments Most vulnerable are shoulder, knee and ankle joints Typically immediate pain and tenderness followed by swelling and eventually discoloration Can be more swollen and more painful than some fractures 16
Dislocations Significant injury Displacement of bone from its normal position in a joint Joint usually forced beyond normal range of motion Can cause damage to blood vessels and nerves by compression or tearing Need treatment sooner than later 17
Dislocation Typical appearance Joint found in abnormal appearance with deformity and possible swelling Pain and tenderness present Inability to move extremity Not recommended to manipulate dislocations but to splint in position found Loss of distal pulses increases the severity of the injury
18 Fractures Loss of continuity of the structure of a bone Sharp fragments may injure surrounding tissue Arteries and bones run throughout the bones Vessels within the bone may tear or rupture and bleed 19
Fractures contd Classified as open or closed Open is associated with an open wound to the skin The wound may be from the outside inward (i.e.: the mechanism of injury from a missile) or from the bone end poking through skin Displaced bones more likely to damage surrounding nerves, blood vessels, muscles, ligaments, and tendons 20
Critical Fractures Femur and pelvis Potential for significant blood loss and development of hypovolemic shock Goal immobilize bony injury AND reduce potential blood loss Bones tend to bleed when injured AND exposed bone ends could lacerate near by vessels Potential blood loss Each femur 1500 ml blood loss Pelvic fracture 2000 ml blood loss 21
Critical Conditions Pulselessness or cyanosis Immobilize extremity Provide expedited transport Note: Limb threatening musculoskeletal injuries take a back seat to life threatening injuries If there is no time to immobilize an orthopedic injury, placing the patient on a backboard allows some immobilization 22
Absence of Distal Pulses Check capillary refill, skin temperature/color and general condition If pulses found, mark site with an x to help find the same pulse site on reassessment Continue to check for sensation and movement Provide rapid transport Splint extremity in position found Document assessment and care provided 23
General Patient Presentation Common presentations of most musculoskeletal injuries Pain Swelling Decreased or lack of movement Inability to bear weight Possible deformity Occasionally blood loss (i.e.: femur, pelvis 24
Assessment of Musculoskeletal System Assessment before and after splinting Assess pulses (can compare to opposite side) Evaluate motor capability Can you wiggle fingers/toes Evaluate sensory status Can you feel me touching fingers/toes? Call it what you want:
PMS CMS - SMV 25 Management of Musculoskeletal Injuries RICE Rest Ice application to reduce swelling
Compression with ACE wrap to reduce swelling Elevation to reduce swelling Reducing swelling reduces the pain level Pain control with medication Distraction 26 Region X Pain Management Same formula for adults and peds
Fentanyl 0.5 mcg/kg IVP/IN/IO May repeat same dose in 5 minutes Max total dose 200 mcg 27 Fentanyl Synthetic opioid narcotic Used for analgesic purposes Properties similar to morphine with less cardiovascular side effects Administer over 2 minutes IVP/IN/IO Watch for respiratory depression,
bradycardia 28 Fentanyl contd Onset - immediate Peak effect 3 5 minutes Duration 30 - 60 minutes IN route used in absence of IV access Administer in divided doses IN route onset 2 minutes 29 Narcan (Naloxone)
Narcotic antagonist Competes for opiate receptor sites in brain Reverses effects of narcotics including synthetics Onset within 2 minutes Dosing- enough to improve ventilations Adults 2 mg IVP/IN/IO Peds > 20 kg 2 mg Peds < 20 kg 0.1 mg/kg
30 Narcan contd Side effects are rare BUT Can cause narcotic withdrawal in narcotic dependent person May present with seizures after administration Effects may not last as long as the narcotic you are countering Watch for relapse of level of consciousness and respiratory effort
31 Compartment Syndrome Complication usually associated with closed injuries to extremities Major muscle groups contained in compartments surrounded by inelastic, non-expanding fascia Pressures usually around 0 Pressures over 30 mmHg can restrict capillary blood flow Irreversible ischemic damage usually occurs at about 10 hours
32 Compartments of the Leg 33 Compartment Syndrome There is excessive swelling in an enclosed space and that space has expanded to full capacity with no more room to expand Skin can only be stretched so far
High pressures impede blood flow and leads to hypoxia of tissues Hypoxic tissues trigger leakiness of capillaries causing further swelling 34 Compartment Syndrome Assessment Develops over time most likely after 6-8 hours Not usually seen in the field immediately after the insult
History in recent past of an injury Prevalent symptom pain out of proportion; pain with passive stretching Typically a deep, burning pain Pain not affected by positioning Motor and sensory usually normal Distal pulses usually present 35 Compartment Syndrome
Intervention In the field, care for the underlying injury Splint and immobilize all potential fractures Apply cold packs as needed Elevate injured extremity Reduces edema Increases venous return Lowers compartment pressure Note: Care may differ in the hospital; limited resources available in the field 36
Immobilization Devices Goal to prevent further injury that could be caused by movement Reduces stress on ligaments, muscles, and tendons Reduces pain by reducing limb motion 37 Golden Rule of Immobilization Immobilize the joint above and the joint below the injury
When applying a splint that wraps an extremity, wrap from a distal to more proximal point This prevents trapping of blood distal to the injury Dont wrap so tight as to impede blood flow Evaluate distal circulation, motor function, and sensation before and after splinting Document findings 38
Traction Splints Proximal femur fractures (surgical neck and intertrochanteric fractures) frequently caused by hip injuries, transmitted forces, or aging Referred to as hip fractures Do not benefit from traction splints If a joint injury is suspected, traction splints should not be used 39 Traction Splints
Purpose Relieve the spasm Relieving spasm decreases the pain Note: Rapid transport for life threatening condition takes priority over placing splints on a patient Immobilization using a full backboard may be the best you can do in those situations
40 HARE Traction For suspected mid-shaft femur fractures 41 HARE Traction Steps 1 rescuer maintains manual traction to foot 2nd rescuer assesses distal CMS/PMS/
SMV 2nd rescuer prepares traction device Place device next to uninjured leg Place pad at ischial crest Adjust length to extend past foot Tighten locking collars 42
HARE Traction Steps contd Open & position velcro straps Open ratchet & extend traction strap Place splint next to injured leg 2nd rescuer applies ankle hitch & takes over applying firm, gentle manual traction via ankle hitch
1st rescuer moves splint into position firmly against ischial tuberosity 43 Ischial Tuberosity Most distal part of the bony pelvis The shape forms the platform for sitting when upright
Structured to support the bodys weight when sitting 44 HARE Traction Steps contd 1st rescuer secures proximal, pubic strap high over the thigh 1st rescuer attaches ankle hitch to traction splint Traction strap tightened until pain & spasm are relieved and stopped when leg lengths are equal
Manual traction stops when mechanical traction takes over and is effective 45 HARE Traction Steps contd Remaining straps secured in place Avoid placing a strap across injury site and knee Support distal traction stand on backboard Backboard most likely will need to be shifted
towards foot end of cot and extend off of cot to support traction stand Reassess distal CMS/PMS/SMV after splinting Document assessment findings and procedure 46 Sager Splint Alternative device for suspected femur fractures
47 Sager Splint contd Place splint between patients legs along medial aspect of injured leg with pulley towards the injured leg Snuggly wrap the ankles with the ankle harness provided Pull control tabs to engage ankle harness tightly against crossbar Grasp the padded shaft of splint with one hand and red traction handle
with the other 48 Sager Splint contd Gently extend the inner shaft until desired traction is achieved Suggested is 10% of patient weight up to 7kg (15#) per leg for unilateral fractures (14 kg (30#) bilateral fractures) Apply remaining straps for a snug fit
Apply figure 8 straps around feet to prevent rotation Recheck distal CMS/SMV/PMS 49 KED Device When extrication does not need to be emergent It takes time and resources to apply 50 KED Device contd
KED slid into position behind the patient Manual head immobilization maintained Middle torso strap applied Bottom torso strap secured Leg straps are secured Can be criss-crossed or fastened to same side Avoid criss-cross if groin injury present Now pad void between head and device and secure head
51 KED Device contd Just prior to moving, top torso strap is secured Not done earlier to prevent restriction or interference of breathing Note: Secure torso prior to securing the head Secure the forehead strap running
strap in a downward direction Secure the chin strap over the cervical collar 52 KED Device 53 KED Device To remove patient from vehicle, grasp the side handles to pivot/tilt/lift the patient
Grasp the side handles and under the patients knees to raise them enough to slide a backboard under them Once patient is extricated and on cot, loosen top strap to allow for chest expansion Loosen groin strap for legs to straighten Readjust remaining straps as necessary for transport 54 KED Device Lightly scrub to remove gross
contaminant after each use Disinfect after each use Allow to air dry prior to placing in the storage bag 55 Case Scenario Review Review the following cases Determine your general impression Determine your treatment approach based on presentation and signs and symptoms
Discuss methods to reduce pain 56 Case Scenario #1 Your patient is an 89 year-old female who fell onto an outstretched hand You note deformity to the wrist VS: B/P 140/92; P 92; R 18 Pain 6/10 57
Case Scenario #1 What is important to ask this patient with regards to her injury? For any patient who fell, important to ask WHY they fell If patient was dizzy, consider a cardiac problem until proven otherwise Document reason for the fall 58 Case Scenario #1
Patient has a wrist injury from a fall Based on mechanism of injury (MOI), what else should be assessed? Evaluate up the extremity to points distal to the injured site Upper extremity evaluate fingers to shoulder including clavicle Lower extremity evaluate toes to hip 59 Case Scenario #1 What is standard assessment for orthopedic injuries?
Evaluate distal CMS/PMS/SMV before and after splinting What is standard treatment for orthopedic injuries? RICE Rest - immobilize Ice not directly applied over site Compression wrap with an ACE Elevate - higher than heart for swelling 60
Case Scenario #1 How would you address this patients pain? RICE Rest, ice, compress, elevate Fentanyl 0.5 mcg/kg IVP/IN/IO Can repeat same dose in 5 minutes if needed Max total dosing is 200 mcg Watch for respiratory depression with this synthetic narcotic 61
Case Scenario #2 You respond to a sports complex for a 17 year-old injured They planted their foot and then rolled/twisted their leg There is obvious deformity to the ankle/foot VS: B/P 118/70; P 82; R 18 Pain 9/10 62 Case Scenario #2 - MOI
63 Case Scenario #2 What would be your initial assessment? MOI Appearance Distal CMC/SMV/PMS before and after splinting Level of pain What is your treatment? RICE
Immobilize in position found 64 Case Scenario #2 How would you address the pain in this 17 year-old? RICE is used Follow Peds Pain Management SOP Same as the adult SOP Fentanyl 0.5 mcg/kg IVP/IN/IO May repeat same dose in 5 minutes is needed
Max total doses is 200 mcg Watch for respiratory depression 65 Case Scenario #2 17 year-old patient states he does not want to be transported What would you do? As a minor, this patient cannot give medical direction or sign a release Contact the parents If unable to contact the parents, transport the patient to the closest appropriate facility
Provide explanation to the patient why you must transport 66 Case Scenario #3 25 year-old male fell off a ladder while cleaning gutters The patient is unconscious GCS 2/2/4 (total 8) There is obvious deformity of the
right femur as you approach The patient has multiple abrasions and contusions There is blood draining from one ear 67 Case Scenario #3 VS: B/P 110/70; P 88; R 16 B/P 120/82; P 72; R 24 B/P 152/78; P 64; R 20 What is your impression? Multiple trauma
Head injury with orthopedic injuries VS indicate increasing intracranial pressure What category trauma is this? Category I Transport to highest level trauma center within 25 minutes 68 Case Scenario #3 Would you take the time to apply a HARE or Sager to this injury?
No, life threats are treated over limb threats Placing a patient on the backboard will need to serve as a splint HARE or Sager splints can be applied later as there is time and resources 69 Case Scenario #3 You are unable to start a peripheral IV on this patient What would you do?
Place an IO As fluid is infusing, the patient becomes agitated and tries to reach for the IO site What would you do? Administer Lidocaine via the IO for pain control Think 50-60-60 Lidocaine 50 mg over 1 minute and wait 1 minute to resume infusion 70 Case Scenario #4 Your 45 year-old patient injured their knee falling
VS: B/P 128/86; P 86; R 16 Pain 5/10 71 Case Scenario #4 You are unable to palpate distal pulses on the injured side What would you do?
Compare circulation to opposite side Contact Medical Control with the finding Splint the injury as found If pulses are found, mark the site with a pen Makes it easier to find the pulse site on reassessment once found 72 Case Scenario #4 What do you do if loss of distal
pulses? Splint in position found Notify receiving hospital of condition Continue to monitor and assess the distal CMS/SMV/PMS status Do not manipulate injuries without contacting Medical Control first Document findings and interventions 73 Case Scenario #5 How do you care for an open wound?
74 Case Scenario #5 Can irrigate with normal saline for gross contaminant Cover wound with moist sterile saline dressing Cover with dry dressing Immobilize extremity Assume any open wound over a bony injury is an open fracture 75
Case Scenario #5 Goal: Reduce/eliminate further risk of contamination Do not manipulate extremity Do not want to inadvertently drag any contaminate into wound 76 Case Scenario #6 Sprain or fracture??? Do you handle a sprain different from
a fracture? Orthopedic/musculoskeletal injuries are handled the same Will need further diagnostics for definitive diagnosis 77 Case Scenario #6 Wounds change appearance after hours to days
Usually develop more swelling and discoloration Bruising from bleeding into surrounding tissue Blood will get reabsorb over time Color of bruise indicates general age of injury Document color of bruise noted versus using words new or old 78 Age of Bruise/Injury 0 - 2 days red 2 5 days blue and purple
5 - 7 days green 7 10 days yellow 10 14 days brown 2 -4 weeks no further evidence 79 Case Scenario #7 Your patient was casted 2 days ago for a fractured fibula/tibia You can see a cast on the lower extremity
Patient complains of pain off the chart They are agitated, miserable, and demanding fro you to do something for the pain Toes are swollen and discolored Capillary refill is present 80 Case Scenario #7 What is your impression? Patient may no have kept leg elevated
Patient may not have filled prescription for pain medication Patient has a low pain tolerance level Worse case scenario: patient has a compartment syndrome This is a true emergency If not recognized and treated promptly, patient may need amputation Outstanding feature: pain out of proportion; pain with passive stretching 81 Case Scenario #7
What can you do in the field for possible compartment syndrome??? Elevate extremity To reduce swelling Apply ice packs to site Can be effective even through a cast Evaluate distal CMS/PMS/SMV and document At the hospital, after evaluation, patient may receive a fasciotomy to relieve intense elevated pressures within the
muscle compartment 82 Case Scenario #7 Fasciotomy left open until pressures go down Patient eventually returns to surgery to have wounds closed 83 Bibliography Bledsoe, B., Porter, R., Cherry, R.
