Elbow Pathophysiology Flashcards
open chain kinematics at elbow are blank on blank
concave on convex
close chain kinematics at elbow are blank on blank
concave, convex
aka tennis elbow
lateral epicondylitis
males and females are blank prone to lateral epicondylitis
equally
lateral epicondylitis is most commonly seen in blank decade
4th
lateral epicondylitis is uncommon before this age
20
75% of cases are blank with respect to dominant hand
ipisilateral
the moi of lateral epicondylitis is blank
questionable
degeneration, sprains, inflammation, and tendonitis can all contribute to the cause of blank
lateral epicondylitis
lat epicondylitis may have pain radiate down blank
forearm
surgery is only used when pt conservative treatment is ineffective for how long
a year
blank manipulation can help lat epicondylitis
cervical
repetitive or heavy motion with elbow flexion or supination can cause blank
bicipital tendonitis
loss of 30-40% strength if there is a blank of the biceps tendon
rupture
most common age range for lateral epicondylitis
40-50
x rays are usually negative for lateral epicondylitis but over time they can reveal blank of blank muscle at origin
calcification, extensor
there is no blank treatment for conservative pt of lateral epicondylitis
long term
less common epicondylitis
medial (golfers)
golfers epicondylitis has pain aggravated by resisted blank
wrist flexion
blank and blank are painful from biceps strain
flexion/supination
blank may be present during biceps strain
hematoma
partial biceps tendon tear would have blank at insertion
palpable tendon
loss of biceps strength will become blank over time with strain
greater
olecranon bursitis is blank to insertion of triceps tendon
superficial
gout is one thing that can contribute to blank
olecranon bursitis
olecranon bursitis is aka
students elbow
olecranon bursitis may present with blank
inflammation
bursitis usually has history of blank unlike infection
trauma
infection can lead to blank
cellulitis
post traumatic ossification that can occur about anywhere
myositis ossificans
new bone formation in abnormal site
heterotopic ossification
three types of osteochondritis
intact, partial, complete
osteochondritis dessicans rest from aggravating activites with splinting
intact
osteochondritis dessicans where articular cartilage is fracture but remains intact
partial
osteochondritis dessicans free loose body within joint capsule
complete
aka panners disease
osteochondrosis
effects capitulum and is due to a loss of blood supply to epiphysis
osteochondrosis
osteochondrosis is from lost blood and is in younger blank
boys
most common and very serious fracture of humerus
supracondylar humeral fracture
foosh with blank is the moi for supracondylar humeral fracture
elbow flexed
humeral fracture can penetrate brachialis, brachial arter, median nerve often which makes it blank
serious
common fracture in young adults that occurs with valgus force applied to extended elbow, concave radius is crushed against convex blank
capitulum, radial fracture
a split between condyles that may displace from the parent bone type of fracture
intracondylar fracture
nursemaids elbow
radial head subluxation
this pulls radial head through the annular ligament with forearm pronated
radial head subluxation
treatment for radial head subluxation
supination of forearm with elbow flexed
humerus is driven forward and radius and ulna go posterior and can damage surrounding structures
posterior elbow dislocation
go through notes cause that ppoint sucked
okay
With a biceps rupture how much of a decrease in flexor strength is there
30%
With a biceps rupture how much of a decrease in supination strength is there
40%
How long are biceps ruptures immobilized at 90 degrees
2 weeks
How many cases of osteochondritis ossifican occur in males
4.1 per 1000
What age gets osteochondritis ossificans almost exclusively
10-50
What age range is most common to have osteochondritis ossificans
9-16
What percent of osteochondritis ossificans patients are males
85%
How long are posterior elbow dislocations immobilized for
7-10 days
