MSK Conditions of the UE Joints Flashcards
What are common complaints for pain with lateral elbow tendinopathy?
What are the risk factors for lateral elbow tendinopathy?
- Pain over lateral epicondyle with wrist extensor load
- pain w/ resisted wrist 2nd or 3rd digit extension
- pain with wrist extensor stretch
- pain w/ grip
Risk Factors:
- 35-54 yrs old
- manual labor
- smoking
- tennis players
What is the pathophysiology for lateral elbow tendinopathy?
How do you treat reactive and degenerative tendon pathology for lat. elbow tendinopathy?
Ext. Carpi Radialis brevis degeneration- merges with LCL and annular ligament and is not inflammatory
Reactive (due to unusual or increased activity load) is treated with reducing or modifying the load on the tendon
Degenerative (more chronic symptoms) is treated with eccentric exercised
If there is a tear in tendon or LCL tear surgery may be indicated, also may be indicated if conservative care fails after 6 months
True or False: Corticosteroids combined with PT have been shown to have better benefit then with PT or injection by themselves
False, corticosteroid shots give very short term benefit as far as pain but actually do not address the tendinopathy and has no added benefit when combined with PT
and PT w/o steroids injection has the lowest 1 yr recurrence and has a 100% complete or much improvement rate
What PT interventions have been shown to be beneficial for Lat. elbow tendinopathy?
- mobilization w/ movement
- strengthening of wrist extensors (con and eccentric)
- wrist manipulation
- treat the impairments
- regional interdependence (shoulder and c-t spine)
What is radial tunnel syndrome?
What are the signs and symptoms?
What is the recommended treatment for RTS?
Compression of the deep branch of the radial nerve via compression at proximal border of supinator/ arcade of frohse
- pain lateral forearm (ro consider C6/7 radicular pain)
- pain w/ wrist, 2nd or 3rd digit extension
- no overt weakness, if weakness is present then consider posterior interosseus nerve entrapment (r/o C6/7 radiculopathy) ((PIN is purely motor)
consider radial nerve mobilization, in addition to addressing lateral elbow pain w/ treatment
What is posterolateral rotary instability?
What are common MOI for this condition?
What are the signs and symptoms?
Varus instability or Lateral UCL complex disruption
- acute trauma
- result of chronic corticosteroid injections
- chronic UE weight bearing
- connective tissue disorders
SxS
- unrestrained supination (radial head dislocates posterior with full/excessive supination)
- clicking, snapping; instability sensation in extension and supinated position
What is the pathology for radiocapitellar injuries?
How do you evaluate and manage this injury?
radiocapitellar compression injury that is associated with throwing injuries secondary to medial instability and usually effects children and adolescents
evaluate for valgus stress and address medial instability
What is the pathology of medial elbow instability?
injury to the UCL, primarily the anterior band from throwing/valgus stresses
- rarely assoc. w/ ADLs
- pop followed by sudden pain, tearing, change in throwing velocity or accuracy
What exam findings would indicate medial elbow instability?
What is typical treatment for this instability?
What population must be aware of epicondylar apophysitis with medial elbow instability?
- positive valgus tests, possibly loss of elbow extension
- positive tenderness along UCL
- possible ulnar nerve involvement
usually reqiures surgery
adolescents due to skeletal immaturity
What are the signs for an Ulnar nerve/ cubital tunnel injury?
- sensory deficits in medial palmar/dorsal hand
- weakness of FDP and lumbricals (D4, D5) and interossei
- positive tinel’s test
- positive hyperflexion test
- r/o C8/T1 radiculopathy
What are the signs of an acute fracture of the elbow?
- loss of extension
- occurs due to rapid hemarthrosis
- inability to extend elbow very shortly after injury (suspect fracture)
(very sensitive test to rule out fracture if no loss of extension is present)
What MOI commonly leads to a radial head fracture?
What is common treatment for this injury?
FOOSH
immobilization if non-displaced
What is a nightstick fracture?
What is a monteggia fracture?
fracture at the midshaft of the ulna
fracture of the proximal ulna with a dislocation of the radial head
What is the cause of myositis ossificans in the elbow?
What muscles are most at risk with MO?
What are the different types of rehab for MO?
contusion, fracture or too aggressive of rehab
brachialis and triceps brachii
conservative: Gentle ROM, ice (no heating agents)
surgical: if ROM remains restricted after conservative care, however high recurrence
What is Dupuytren’s contracture?
What can it progress into?
Where does it occasionally present besides the hand?
-palmar fascia dimpling/puckering the skin with visible raised cord or nodules along the flexor tendons
progresses to causing flexion contractures
plantar fascia and in the penis
