Musculoskeletal Flashcards
Humeroulnar open/closed packed position
Open- 70 flexion, 10 supination
closed- full extension and supination
Humeroradial open/closed packed position
open- full extension and supination
closed- 90 flexion 5 supination
Hip open/closed (bony and ligamentous) packed position
open-30 flexion, 30 abduction, slight ER
closed ligamentous- full extension, abduction, and IR
closed bony- 90 flexion, slight abduction, slight ER (captain morgan)
Knee open packed position
25 flexion
Glenohumeral capsular pattern
- greater limitation in ER, followed by abduction and IR
Elbow capsular pattern
loss of flexion more than extension
Hip capsular pattern
limited flexion and IR, some limited abduction
Knee capsular pattern
flexion limited, slight extension limitation
Scapula bony landmarks
- covers 2nd-7th ribs
- glenoid fossa faces anteriorly, laterally and superiorly, this causes true abduction(scaption) to be at 30 degrees anterior to frontal plane
C4 myotome
shoulder shrug (upper traps)
C5 myotome
shoulder abduction, flexion, extension (deltoid)
C6 myotome
elbow flexion and forearm supination (biceps)
C7 myotome
wrist ulnar flexion and elbow extension
C8 myotome
finge flexion, thumb MCP abduction
C5 reflex
biceps
C6 reflex
brachioradialis
C7 reflex
Triceps
Ulnar nerve innervations (6)
Flexor carpi ulnaris, adductor pollicis, abductor digiti, opponens digiti, flexor digiti quinti, interossei
Median nerve innervations (8)
Pronator group, flexor carpi radialis, palmaris longus, flexor digitorum, flexor pollicis longus, abductor pollicis brevis, flexor pollicis brevis, opponens pollicis
Radial nerve innervations (9)
brachioradialis, triceps, extensor carpi radialis, extensor digitorum, extensor carpi ulnaris, supinator, abductor pollicis longus, extensor pollicis longus/brevis, extensor indici
Ulnar nerve cord segments
C7-1
Median nerve cord segments
C6-T1
Radial nerve cord segments
C6-C8
Scapulothoracic and glenohumeral rhythm
-2:1 ratio
-first 30-60 occurs in glenohumeral
-120 at glenohumeral
60 at scapulothoracic
Normal angle of inclination and coxa vara/valga
Normal - 115-125
Coxa Vara- < 115
Coxa valga > 125
Femoral neck anterior rotation
normal - 10-15
Anteversion- 25-30
Retroversion - <10
L2 myotome
hip flexion and sartorious
L3 myotome
knee extension
L4 myotome
ankle dorsiflexion
L5 myotome
great toe extension
S1 myotome
foot eversion (fibularis longus/brevis)
SI joint nutation
flexion of sacrum with posterior rotation of Ilium
SI joint counter nutation
extension of sacrum with anterior rotation of Ilium
TMJ functional ROM (3 components
- 40mm opening
- 25mm rotation
- 15mm translatory glide
SI joint nutation
flexion of sacrum with posterior rotation of Ilium
SI joint counter nutation
extension of sacrum with anterior rotation of Ilium
TMJ functional ROM (3 components
- 40mm opening
- 25mm rotation
- 15mm translatory glide
Ankylosing spondylitits
- morning stiffness
- PROM and AROM loss
- mostly male
- flexed posture of entire spine
- normal reflexes and sensation
Gout
- deposit of uric acid crystals onto peripheral joints
- often at knee or great toe
- early ID is important
Psoriatic arthritis
- Erosive degeneration in digits and axial skeleton
- both sexes
- acetaminophen, NSAID, corticosteroids
Rheunatoid arthritis
- usually MCP and PIPs, can get ulnar drift
- women 2-3x more likely
- Juvenile RA= onset prior to 16 with 75% remission
Osteoporosis
- metabolic disease depletes bone mineral density/mass
- women 10x more
- common fx sites= T/L spine, femoral neck, humerus, radius
- Meds=calcium, vitamin D
Osteomalacia
-decalcification of bones d/t Vitamin D deficiency
sxs= severe pain, fxs, weakness, deformities,
