Q

The deep fibers of the radioulnar ligaments attach to…

Q

Role of proper collateral and accessory collateral in thumb MCP joint stability

A

PCL is primary restraint to radial deviation w/ MCPJ in flexion.

ACL provides restraint to radial deviation w/ MCPJ in extension.

radioscaphoid arthritis

22
Q

SNAC Stage 3

A

scaphocapitate and lunocapitate arthritis

23
Q

SNAC Stage 4

A

pancarapal DJD

24
Q

Continuing pain with dorsal chip triquetral fracture after SAC, think…

A

DIC/DRC ligament injury

25
Q

The scapholunate ligament is strongest…

A

dorsally.

26
Q

The lunotriquetral ligament is strongest…

A

palmarly.

27
Q

The scaphoid tends to…

A

palmar flex.

28
Q

The triquetrum tends to…

A

dorsiflex.

29
Q

The lunate is “along for the ride” so if you have division of the scapholunate ligament, the lunate willl.

A

extend because it goes with the triquetrum (DISI).

30
Q

Gold standard for dx of schapholunate ligament injury

A

arthroscopy

31
Q

Division of the lunotriquetral ligament will cause the lunate to…

A

flex with the scaphoid (VISI).

32
Q

Sequence of events with perilunate dislocation

A

SL ligament disrupted (can have scaphoid fx) –>
capitolunate dissociation –>
lunotriquetral disruption (can have triquetral fx) –>
failure of dorsal radiocarpal ligaments –> lunate dislocation

33
Q

Treatment of perilunate dislocation

A

-use dorsal approach to fix SL and volar approach to fix LT and perform CTR

34
Q

The primary blood supply to the scaphoid enters at the…

A

oblique dorsal ridge.

35
Q

Deforming forces of MC base fractures

A

2nd CMC: ECRL
3rd CMC: ECRB
5th CMC: ECU

36
Q

There is apex dorsal angulation of MC neck fracutres 2/2…

A

intrinsic pull.

37
Q

5 degrees of rotation at MC leads to…

A

1.5 cm overlap

38
Q

MC shortening of 2 mm leads to…

A

7 degrees extensor lag

39
Q

What ligament prevents dorsal dislocation of the 1st CMC joint?

A

dorsoradial

40
Q

Treatment of extra-articular (epibasal) thumb MC fractures

A

< 30 degrees of angulation well tolerated non-op

> 30 degrees , CRPP (otherwise can get MCPJ hyperextension)

41
Q

With pinch, force seen at IP, MCP and CMC joints of the thumb

A

IP 4x
MP 6 x
CMC 12 x

42
Q

Arthroplasty of the DIP is associated with…

A

extensor lag.

44
Q

Schapholunate ligament rupture can be associated with…

A

gout.

45
Q

Which cord causes contracture of the DIP joint in Dupuytren’s?

A

retrovascular

46
Q

Parona’s space lies between…

A

the fascia of the pronator quadratus and FDP conjointed tendon sheaths.

47
Q

The attachments of the transverse carpal ligament include…

A

scaphoid and trapezium radially and pisiform and hook of hamate ulnarly

48
Q

The medial femoral condyle vascularized graft is supplied by….

A

the longitudinal branch of the descending geniculate artery.
