impingement/ subacromial bursitis

A

most common source of shouler pain

caused by repetative overhead activities.

S+S: pain in ‘impingement’ arcs, pain lying on that side.

radiographs bilaterally to evaluate for structural change.
USS to look for bursa etc.

5 main types
skin elasticity
joint hypermobility
vascular type- prone to bruising easily
ocular-kyphoscoliosis type
arthrokalasis type- B/L congen hip dislocation.

Q

inherited connective tissue disorders- marfans

A

autosomal dominant

mutation in fibrillin-1 gene (cr 15) – decreaces production of extracellular microfibril

this maintains and forms elastic fibres (skin lig bones) to stretch. - deficient in marfans.

S+S:
major signs- long limbs, tall, thin, spindly, thumb extends beyond clenched fist.

upward lens dislocation
pectus deformity (excavatum)
aortic dissection (root stretched)

minor signs: mitral prolapse, high arched palate, hypermobile, knee hyperextension, scoliosis, dec subcut fat.

Rx: incurable
prevent cardiac shenanigans
B blockers
annual echos- 5cm or more dilatation- surgical repair.

Q

discuss both medial and lateral epidoncylitis

A

a chronic inflammatory condition of the common origins of the tendons

over use syndrome

peak onset 35-54 years old.

medial and lateral can be affected.

RF: repetitive mvt, work, hobbies etc.

S+S: pain rediating into the forearm. pain on palp. reduced grip strength.

cozens and mills test- help with the CLINICAL DIAGNOSIS.

Rx: activity modification, NSAIDS (topical or not)
steroids can help
physio/ orthosis.

debridement of tendon can be done if recalcitrant.

muscles affectes: medial- flexor carpi radialis, pronator teres

Q

raynaulds phenomenon

A

a vascular condition- arterial vasoconstriction

caused by cold temps or stress.

S+S: numbness, tingling, discolouration- all in digits.

is a syndrome when assoc with connective tissue disease.
its a disease when no other causes.

THUMB is spared usually.

frostbite predisposes to this condition.
