Musculoskeletal Flashcards
Adolescents
Decreased strength in the epiphyses, overall decreased strength and flexibility lead to potential for injury
Bone growth is completed at 20 years
Peak bone mass reached at 35 years
Pregnancy
Increased hormone levels contribute to the elasticity of ligaments and softening of cartilage in the pelvis at 12-20 weeks
Lordosis may cause low back pain
Older adults
By 80 years, woman can lose up to 30% of bone mass
Risk factors for osteoporosis
Race (white, Native American) Thin Family hx Nulliparous Sedentary lifestyle Menopause before 45 years Scoliosis, RA, CA, MS, fractures Dieting, inadequate Vit D, excess carbonated beverages Drugs: thyroxine, corticosteroids, heparin, lithium, anticonvulsants, antacids Cigarettes, alcohol
Inspection
Lordosis, kyphosis, scoliosis
Skin and subQ tissues overlying muscles, cartilage, bones, joints
Muscle wasting - s/p injury
Fasciculation occurs after injury to muscle’s motor neuron
Palpation
Note heat, tenderness, swelling, crepitus, pain, resistance to P
Synovial thickening sometimes felt in joints that are close to the skin surface when the synovium is edematous or hypertrophied
Muscle Function Level Score
0 - No evidence of movement
1 - Trace of movement
2 - Full ROM but not against gravity
3 - Full ROM against gravity NOT against resistance
4 - Full ROM against gravity and SOME resistance, weak
5 - Full ROM against gravity, FULL resistance
Heberden nodes
Located along distal interphalangeal joints
Bouchard nodes
Located along proximal interphalangeal joints
Hands/wrist ROM
Bend the fingers forward at the metacarpophalangeal joint, then stretch the fingers up and back and the knuckle
Flexion = 90
Hyperextension = 30
Touch thumb to all fingertips and to the base of the little finger, make a fist
Spread fingers apart and then touch together
Bend the hand at the wrist up and down
Flexion = 90
Extension = 70
Palm side down, turn hand right and left
Radial = 20
Ulnar = 55
Unexpected hand findings
Ulnar deviation and subluxation of metacarpophalangeal joints
Swan neck
Boutonniere deformity
Unexpected elbow findings
SubQ nodules = RA or gouty tophi
Boggy, soft, fluctuant swelling = epicondylitis or tendonitis
Point tenderness at the lateral epicondyles
Elbow ROM
Elbox fully extends, bend and straighten the elbow Flexion = 160 up Extension = 180 down Rotate hand in/out Pronation = 90 Supination = 90
Inspect/palpate elbow
Flex to 70, palpate the extensor surface of the ulna, olecranon process, medial and lateral epicondyles of the humerus
Shoulders
Inspect contour, shoulder girdle, clavicles, scapulae, surrounding musculature
Suspect shoulder dislocation
Contour is asymmetric, one shoulder hollows in the rounding contour, winged scapula (outward prominence of the scapula)
Shoulder ROM
Shrug - symmetrical
Raise both arms forward and straight up over the head = 180
Extend and stretch both arms behind back = 50 hyperextension
Lift both arms laterally and straight up over head = 180 abduction
Swing each arm across front of body = 50 adduction
Arms behind hips elbows out = 90 internal rotation
Arms behind head elbows out = 90 external rotation
CN XI = shrug against resistance
Temporomandibular joint
Open/close space 3-6 cm between upper and lower teeth
Laterally move side to side 1-2 cm in each direction
Protrude and retract chin
CN V clench teeth palpate contracted muscles
Cervical spine ROM
Chin to chest = 45 Extension = 45 Bend head side to side = 40 Turn head side to side = 70 Do above with resistance checks CN XI
Gibbus
Sharp angular deformity
Associated with collapsed vertebra from OA
Thoracic and lumbar ROM
Bend at waist = 75-90 no knee bend
Hyperextension = 30
Side to side lateral = 35
Rotate upper trunk while stabilize hips = 30 front and back
Hips ROM
Supine, raise leg with knee extended = 90
Standing or prone, swing straight leg back = 30
Knee to chest = 120
Adduction = 30 straight leg across body
Abduction = 45 straight leg out
Knee bent, internal rotation = 40
Flexed knee to table (FABER) = 45 Flex ABduct Externally Rotate
Gena valgum
Knock knees
Genu varum
Bow legs
Genu recurvatum
Excessive hyperextension of the knee with weight bearing = weak quads
Baker cyst
Popliteal cyst
Knee ROM
Bend = 130
Straighten and stretch = 15 hyperextension
Pes varus
In-toeing
Pes valgus
Out-toeing
Pes planus
Flat foot
