MSK Flashcards
What is the convex-concave rule?
Convex-concave -
covex surface moves/glides OPPOSITE to proximal part/shaft of bone (ie. humerus on labrum in shoulder flexion or abd)
Concave-convex - concave surface moves/glides in the SAME direction to proximal part/shaft of bone (ie. ulna on humerus in elbow flexion)
What are normal end-feels?
Soft
Firm
Hard
What do the types of pathological end-feels feel like? Boggy? Firm? Rubbery? Empty? Hypermobility?
Boggy- edema, joint swelling
Firm with decreased elasticity- fibrosis of soft tissue
Rubbery- muscle spasm
Empty- losse, then hard, muscle guarding
Hypermobility- edn feel at later time than opp side
What are symptoms of DJD?
pain/stiffness on rising pain eases through morning 4-5 hours pain increases with repetition/bending constant awareness of discomfort with episodes of exacerbation soreness and nagging pain
What are symptoms of facet joint dysfunction?
stiff upon rising pain eases within 1 hour loss of motion sharp pain movement in pain-free range reduces symptoms stationary positions increase symptoms
What are symptoms of disc dysfunction with nerve root impingement?
no pain in reclined position
pain increases with increasing weight bearing activities
shoorting, burning, stabbing pain
altered strength and ability to perform ADLs
What are symptoms of spinal stenosis?
pain in related position flexed position decreases pain extended position increases pain numbness, tightness, cramping walking increases symptoms pain persists for hours after assuming resting position
What are symptoms of vascular clauditcation?
consistant pain in all spinal positions pain starts with physical exertion relieved with rest within 1-5 min numbness decreased/absent pulse
What are symptoms of neoplastic disease?
gnawing, intense, penetrating pain
pain will wake patient at night
pain not resloved by position change, time of day, or activity level
What are x-rays for?
bony tissues, dysfunction of bones
What is CT used for?
complex fractures, facet dysfunction, disc disease, stenosis, soft tissue structures
What is discography used for?
dye infected into disc to identify abnormalities in annulus or nucleus
What is MRI used for?
excellet visualization of tissue anatomy
T1 for bony anatomy
T2 for soft tissue
What is arthrography used for?
identifies abnormalities within joints ie. tendon ruptures
What are bone scans for?
RA, stress fracture, bone cancer, bone infection
detects ‘hot spots’ of increased metabolic activity
