MSK UE Flashcards
(41 cards)
(true/false) bacterial endocarditis often presents at the shoulder
true
RTC pathologies will have a (low/high)-riding humeral head
high-riding
Head is pulled up due to the spastic muscles which narrows the coracoacromial space
How long can a surgeon wait to repair a supraspinatus tear? What can happen if they wait too long?
a. approx. 8-10 months
b. if the tendon is retracted too much, the surgery is less likely to connect the tendon in its original position = leads to achoring the tendon onto the humeral head which changes shoulder mechanics
What is a Bankhart lesion? What is the MOI?
a. anteroinferior glenoid labral tear with fracture of the glenoid
b. Anterior shoulder dislocation
increases the risk of shoulder dislocation and capsule damage
What is a hill-sachs lesion? What is the MOI?
a. Fracture of the posterolateral humeral head
b. posterior shoulder dislocation
What is a reverse hill-sachs lesion? What is the MOI?
a. Fracture of the anteromedial aspect of the humeral head
b. posterior dislocation
How long can bruising caused by bakhart lesion and/or hill-sachs lesion last?
10-12 months
What type of acromion abnormality is the worst?
Type 3
curved acromion that looks like the end of a field hockey stick
What is the surgical intervention for the supraspinatus after being damaged by the acromion?
SAD procedure
Subacromial decompression that removes the distal end of the acromion
4 weeks of recovery (easiest to recover from)
What type(s) of acromion curve(s) minimally respond to conservative intervention?
Types 2 and 3
What is the CPR for diagnostic imaging of elbow injuries?
NO emergent imaging if the patient has NORMAL extension, flexion, and supination
(true/false) It takes a short amount of time for an olecranon fracture to heal
FALSE
What are common MOIs for olecranon fractures?
- FOOSH with elbow EXT
- falling/direct blow to the elbow
What is the Sail sign? What does it suggest?
definition: Fat pads between the bone and muscles are fanned out due to bleeding around the joint
- suggestive of an occult radial head fracture
occlusion is commonly hidden which is why the sail sign is helpful w/ dx
What are red flags indicating a possible radial head fracture?
- FOOSH
- Sail sign
- arm being held in OPP
- restricted/painful PRON/SUP AROM
- radial head TTP
What are common medial nerve entrapment sites?
- between the heads of PT
- carpal tunnel
What are common ulnar nerve entrapment sites?
- ulnar groove
- between heads of FCU
- Guyon’s canal
What are the common radial nerve entrapment sites?
- triangular interval
- supinator
Note: pierces the supinator (deep radial nerve)
What are red flags that can be indicative of compartment syndrome in the UE?
- trauma, surgery, extreme unaccustomed activity
- persistent forearm pain and tightness
- tingling, burning, or numbness
- TTP and tension of the compartment
- pain increases with stretching
- paresthesia, paresis, sensory deficit
- diminished pulse and capillary refill
What is the technical term for a “dinner fork fracture”?
colle’s Fx
(true/false) Colle’s Fx and smith Fx are the same fx
true BUT they are distinguished between the position/movement of the wrist
What is a smith fx?
Flexion fracture of the radius
What is a colle’s fracture?
Extension fracture of the radius
What are red flags that suggest scaphoid fractures?
- FOOSH
- male 15-30
- females with osteoporosis
- swelling and bruising around the wrist
- TTP over anatomical snuff box/scaphoid tubercle
- increased pain with gripping
