Musculoskeletal Part Twelve Flashcards
though potentially not sensitive enough, what diagnostic test is best for bicepital tendonosis
MRI
three conditions commonly paired with carpal tunnel syndrome
pregnancy
diabetes
RA
long term compression of median nerve results in
atrophy and weakness of thenar muscles AND lateral two lumbricals
does proximal humerus fracture require immobilization/surgical repair? why not?
it does not because it is a fairly stable fracture
Volkmann’s ischemia is the result of
problems following supracondylar fractures with neuro and vascular
MOI posterolateral dislocation of elbow
FOOSH with elbow hyperextended
tendons involved with de Quervanin’s
APL
EPB
splinting the elbow (in combo with PT) may be helpful with
regaining loss of motion for capsular restrictions
de Quervain’s occurs as a result of
repetitive microtrauma
complication of swelling during pregnancy
what is weakened with de Quervain’s
grip and pinch strength
osteochondritis dissecans affects….
capitulum
radial head
what does dinner fork deformity result from
colles fracture
at night, what can help entrapped nerves
protective padding
night splints
(anything to maintain slackened position)
what is important EARLY for proximal humerus fractures and why
early PROM to prevent capsular adhesions
most common wrist fracture
Colles Fracture
what is Panner’s disease
localized avascular necrosis of capitulum
what is osteochondritis dissecans
osteochondral bone fragment becomes detached from articular surface
forms loose body in joint
capsular pattern elbow
flexion > extension
UCL injury follows
repetitive valgus stresses to medial elbow with overhead throwing
someone with lateral epicondylitis should avoid gripping/lifting things with…
palm down
why can supracondylar fractures be extremely important
lots of neurological and vascular structures passing through (radial nerve)
two motions most associated with those with medial epicondylitis
strong hand grip
excessive pronation
MOI greater tuberosity fractures
fall onto the shoulder
what two other diseases is adhesive capsulitis paired with
diabetes
thyroid
what tendons are involved with medial epicondylitis
pronator teres
Flexor carpi radialis
how long are Colles Fractures immobilized for
5-8 weeks
the elbow most commonly dislocates in what direction
posteriorly (posterolateral specifically)
who is more susecptible to greater tuberosity fractures
middle-aged and older adults
what is osteochondritis dissecans caused by
repetitive compressive forces between radial head and humeral capitellum
why are rotator cuff tendons susceptible to tendonitis
relatively poor blood supply near insertion of muscles
where would there be pain for de Quervain’s
anatomical snuff box
are anterior and radial head dislocations common
no (1-2%)
what muscle would have pain with radial nerve entrapment
supinator
do greater tuberosity fractures require immobilization for healing
NOPE
what is lateral epicondylitis
chronic degeneration of ECRB at proximal attachment to lateral epicondyle of humerus
what should be avoided with osteochondritis dissecans
throwing
UE loading activies (gymnastics)
what two things must be ruled out with lateral epicondylitis
c-spine
radial nerve entrapment
in PT, following resolution of pain and inflammation, what should be focused on with UCL injuries
strengthening of elbow flexors
the distal branch of the radial nerve (______ nerve) can become entrapped in the radial tunnel
posterior interosseous nerve
motions most restricted with adhesive capsuliitis
ER most
ABD = flexion
IR least
following surgical repair of shoulder impingement, what motion should be avoided
elevation over 90
what type of humerus fracture requires ORIF to ensure absolute alignment
lateral epicondyle
internal (posterior) impingement is….
irritation between:
rotator cuff and greater tuberosity
or
posterior glenoid and labrum
counterforce bracing is commonly used with lateral epicondylitis.. why tho
reduces forces along ECRB
with a complete elbow dislocation, what ligament will rupture
UCL
with excessive edema from Colles Fracture, what can result in what
median nerve compression
what else may result from posterior elbow dislocation
avulsion of medial epicondyle
aside from the rotator cuff tendons, what else can the subacromial/subdeltoid bursas be impinged beneath
the acromial arch
MOI proximal humeral (humeral neck) fractures
FOOSH with older osteoporotic women
initial emphasis for lateral epicondylitis should include
eccentric exercise
