Lunate normally dislocated in what direction and what mechanism?

A

forceful hyperextension

dislocated anteriorly-palmar side

17
Q

Fracture normally occurs with a fall or more commonly holding equipment while getting hit

A

Hamate

18
Q

Wrist ganglion

A

synovial cyst- herniation of capsule, synovial sheath (clear, mucinous fluid)

19
Q

Trigger finger or thumb Mechanism S/S

A

stenosing tenosynovitis in flexor tendon-thickening of sliding tendon +
nodule in synovium making it hard to glide
Overuse
Inflammation of tendon sheath, swelling, pain in wrist extensors, flexion
pain w/ resistance to re-extension, lump felt at base of flexor tendon
sheath

20
Q

Mallet finger aka? Mechanism? S/S

A

Extensor tendon avulsion
Blow from an object that strikes tip of finger
Unable to extend finger (carries at 30 degree angle),

21
Q

Boutonniere Deformity S/S

A

rupture of extensor tendon dorsal to middle phalanx

Unable to extend PIP

22
Q

Jersey finger aka? S/S

A

Flexor digitorum profundus rupture

Unable to flex DIP (extended position)

23
Q

Dupuytren’s contracture S/S

A

nodules in palmar aponeurosis limiting finger extension leading to flexion
deformity
ring or little finger moves into palm of hand

24
Q

Gamekeepers Thumb

A

sprain of ulnar collateral lig of MCP joint

25
Q

Splinting for interphalangeal joint sprains

A

PIP splinting at 30-40 degrees of flexion for 10 days + use protective
checkrein

26
Q

Swan neck deformity: May result in what? S/S? Splinting?

A

avulsion PIP volar plate
may cause pseudoboutineire deformity)
PIP can be passively hyperextended more
Splinted in 20-30 degrees of flexion

27
Q

Splinting for PIP dorsal vs palmar dislocation

A

Dorsal - flexion splint

Palmar- extension splint

28
Q

Bennett’s fracture

A

Fracture at base of first metacarpal (CMC joint)

29

Clubbing/Cyanosis?
Scaling/ridging
Spooning/depression
Ridging (vertical)/ poor development
A

Clubbing/cyanosis- congenital heart disorder or chronic respiratory
disease
Scaling or ridging-psoriasis
Spooning or depression- thyroid issue or iron deficiency anemia
Ridging(vertical) or poor development- nutritional deficiencies

30

Scaphoid and lunate

*Ulna doesn’t interact with the carpals

32
