Class 1 Flashcards
What is a sprain
overstretch/tear to ligament
Signs of strains
pain, swelling, bruising
Grade 1 sprain (mild)
minor tear, minimal pain, continue ADL’s
Grade 2 sprain (moderate)
partial tear, moderate pain, some loss of function
Grade 3 sprain (severe)
complete tear, severe pain, instability, no weight bearing
Joint effusion
excess synovial fluid in joint
Hemaarthrosis
bleeding into synovial space
Why ligaments heal slowly
scar tissue 6 weeks to develop/ 6 months to provide full strength
Ankle lateral ligaments likely which sprain
Inversion
Most common ankle sprain
Anterior talofibular
Common knee sprains
PCL, ACL, MCL, LCL
Terrible triad structures
medial meniscus, ACL, MCL
Most common wrist sprain
palmar radiocarpal
Common shoulder sprain
Acromioclavicular
Grade 1 and 2 sprain treatment
R.I.C.E
Grade 3 sprain treatment
Surgury/ braced 10 weeks
What is a strain
Overstretch to musculotendinous unit
Acute strain
sudden overstretch or extreme contraction
Chronic strain caused by
Overuse
Concentric contraction
O + I closer together
Eccentric contraction
O + I further apart
Grade 1 strain (mild)
Mild swelling/pain, continue ADL’s, 2-3 weeks heal
Grade 2 strain (moderate)
Difficult ADL’s, 3-6 weeks heal,
Grade 3 strain (severe)
Complete muscle rupture, severe pain, no ADL’s, 3 months healing
Grade 1-2 strain treatment
Rest + rehab
Grade 3 strain treatment
Surgery
Contusion
Crush injury to muscle (bruising)
Cause of contusion
direct blow to muscle
Mild contusion
minor crush, continue ADL’s, minimal loss ROM/strength
Moderate contusion
20-50% loss ROM, moderate pain, difficult ADL’s
Severe contusion
> 50% loss ROM, no ADL’s, severe pain
Hematoma
Pooling of blood (bruise)
Myositis Ossificans
Blood turns into small bone pieces
effects of Myositis Ossificans
muscle strength decrease, spasms, local inflammation
Cruciate ligament does what
check motion at knee in extension
ACL
Prevents knee extension
PCL
Prevents posterior tibia movement on femur
Management of cruciate injuries
rest, surgery, rehabilitation
Menisci
Provide shock absorption 30-55% of load at knee
Medial menisci shape
Semicircle (C)
Lateral menisci shape
Almost complete circle (O)
Cause of menisci injury
Twisting while foot planted
Spasms
Involuntary, sustained muscle contraction
Cramp
Prolonged muscle spasm
Reflex muscle guarding
Spasm in response to pain
Intrinsic muscle spasm
Prolonged contraction due to local circulatory changes
Muscle tone
Resistance of relaxed muscle to passive stretch
Muscle tension
muscle held in sustained contraction
Neurologists hypertonicity
upper motor neuron disorders
osteopathic hypertonicity
increase present with painful muscles
Spasticity
Increased tone in response to stretch
Rigidity
Continuous contraction
trigger point
hyperirritable spot in taut band of muscle
Active trigger point
Painful at rest, tender
Latent trigger point
produces pain when palpated
Primary trigger point caused by
Acute or chronic strain or overload
Secondary trigger point caused by
In overworked synergist or antagonist muscles
Satellite trigger point
In referral pattern of another trigger point
Myopathy
Muscle disease
Myalgia
Muscle pain
Myotonia
Slow relaxation of muscle
Myositis
Muscle inflammation
