Q

ankle sprain grades

A

⦁ Grade I = ligament stretched or slightly torn
⦁ Grade II = ligament partially torn
⦁ Grade III = ligament completely torn

FUNCTIONAL LOSS

  • grade I = minimal
  • grade II = moderate
  • grade III = maximum

INSTABILITY

  • grade I = none
  • grade II = moderate
  • grade III = marked

Q

how do sprains & strains occur

A

⦁ Carrying, holding, or restraining items, people or animals
⦁ Lifting, pushing, holding or pulling loads
⦁ Working in a fixed position with the back bent, sitting or standing continuously, or driving vehicles for long periods
⦁ Repetitive tasks such as reaching to lift or lower objects, or to grip tools continuously
⦁ Working in awkward positions involving bending or twisting your body to reach items
⦁ Vibrations through the body like driving a truck or using a powered hand tool

Q

what occupations do strains/sprains occur often in

A
  • Construction
  • Agriculture
  • Trucking / transportation
  • Food services
  • Delivery services
  • Custodial services
17
Q

SIGNS/SYMPTOMS OF SPRAIN (injury/tear of ligament)

A

⦁ pain
⦁ swelling
⦁ bruising
⦁ not being able to move the joint**

18
Q

SIGNS/SYMPTOMS OF STRAIN (injury/tear to muscle or tendon)

A 
⦁	pain
⦁	muscle spasms***
⦁	muscle weakness***
⦁	swelling
⦁	cramping
⦁	difficulty moving the muscle***

difference = muscle spasms / muscle weakness
also have difficulty moving the muscle, whereas with sprains = not able to move joint

19
Q

SPRAIN TREATMENT - 1st stage

A

RICE

  • rest
  • ice
  • compress
  • elevate

REST the injured area (reduce regular exercise or activities as needed)

ICE the injured area, 20 minutes at a time, four to eight times a day (cold pack, ice bag, or plastic bag filled with crushed ice and wrapped in a towel can be used)

COMPRESS the injured area, using bandages, casts, boots, elastic wraps or splints to help reduce swelling

ELEVATE the injured area, above the level of the heart, to help decrease swelling while you are lying or sitting down

20
Q

SPLINTS fall under which RICE treatment for sprains

A

compression

using bandages, casts, boots, elastic wraps or splints to help reduce swelling

21
Q

posterior splint vs stirrup splint

A

similar to posterior splint, but less inversion / eversion, and less plantar flexion compared to posterior splint

  • great for ankle sprains
  • 12-15 layers of 4-6 inch plaster

leave on for 10 days; f/u as needed

22
Q

for moderate & severe sprains

A

o Moderate sprain
- may require the use of mobility aids: cane, crutches, walker or wheelchair

o Severe sprain

  • may need surgery to repair torn ligaments, muscles or tendons
  • short course of narcotic analgesic may be necessary if grade III sprain with severe pain

still use

  • NSAIDS
  • RICE
  • weight bearing as tolerated
23
Q

WHEN TO XRAY ANKLE SPRAINS = OTTAWA RULES

A
  • ankle X-ray only required if there is any pain in the malleolar zone, and any one of the following:

⦁ bone tenderness along the distal 6 cm of the posterior edge of the tibia or tip of medial malleolus

⦁ Bone tenderness along the distal 6 cm of the posterior edge of the fibula or tip of the lateral malleolus

⦁ An inability to bear weight both immediately and in the emergency department for four steps

24
Q

SPRAIN TREATMENT - 2ND STAGE

A

o REHAB

⦁ Physical Therapy / exercise program: designed to help reduce swelling, prevent stiffness and restore normal, pain-free range of motion - during 1st week after injury

⦁ Increase strength & flexibility - usually do more demanding exercises to improve function - during 2nd week after injury

⦁ Return to full daily activities, including sports if appropriate; must work closely with PT to avoid re-injury

25
Q

TREATMENT OF STRAINS (much simpler)

A
  • Rest
  • Alternate Ice / Heat
  • NSAIDS
  • Muscle relaxers if accompanied by spasm
  • Advance to stretching / ROM exercises
  • Refer to PT if indicated
26
Q

TIME NEEDED FOR FULL RECOVERY

HEALING TIME FOR STRAINS / SPRAINS

A

⦁ mild sprain / strain = 3-6 weeks
⦁ moderate sprain / strain = 2-3 months
⦁ severe sprain / strain = 8-12 months
