Normal finger active flexion
ANSWERS: PIP joint flexes first
Extensor tendons proximal to juncturae tendinum
ANSWERS: ruptures of these can be missed due to extension through adjacent
tendons
Evans' Short Arc Motion extensor tendons
ANSWERS: Wrist placed in 30 degrees flexion, then templates for 30 degrees
flexion PIP and 25 degrees flexion DIP, then advance as no extensor lag
present
Extensor tendon repair proximal to JT
ANSWERS: all fingers placed in orthosis in extension
Extensor tendon repair distal to JT
ANSWERS: affected digit in full extension, adjacent digits in 30 degrees MP
flexion
,Yoke splint
ANSWERS: for RF {RF+MF}; for MF {MF}; for SF {SF+IF}; for IF {IF+SF}
Boutonniere deformity
ANSWERS: lateral bands sublux volarly due to attenuation of Triangular Ligament
(and tightening of Transverse Retinacular Ligaments) - ORL gets tight with a
Boutonniere
Address PIP extension lags with reverse blocking
ANSWERS: MP in hyper flexion and work on PIP extension
Central slip initiates extension at PIP joint
ANSWERS: Elson's test assesses central slip integrity at edge of table
Pseudo-boutonniere
ANSWERS: dorsal dislocation/hyperextension/volar plate injury/contracture
- no DIP hyperextension or ORL tightness
CID
ANSWERS: carpal instability dissociative - same row
CIND
ANSWERS: carpal instability non-dissociative - between rows
,CIC (carpal instability combined)
ANSWERS: combination of CID and CIND
adaptive carpus
ANSWERS: instability d/t extrinsic cause like a malunited distal radius fx
DISI
ANSWERS: SL injury - scaphoid flexes and lunate/triquetrum extend
VISI
ANSWERS: LT injury - scaphoid/lunate flex and triquetrum extends
Palmar midcarpal instability (MCI)
ANSWERS: CIND - presents volar sag at ulnar side of wrist w/ clunk when moving
into ulnar deviation and decreased grip strength
ECU and FCU and hypothenars
ANSWERS: start strengthening these in supination for MCI
SL friendly muscles
ANSWERS: FCU, APL, ECRL (dart thrower's motion)
, proximal row carpectomy
ANSWERS: procedure for SLAC wrist, Kienbock's, Prieser's (not for capitolunate
arthritis)
Proximal Row Carpectomy
ANSWERS: painfree motion is goal for this procedure
Dorsal wrist is less supported by ligaments
ANSWERS: volar wrist has more ligamentous stability
Proximal carpal row flexes (and UD) with radial deviation
ANSWERS: Proximal carpal row extends (and RD) with ulnar deviation
with progressive perilunate instability
ANSWERS: lunate dislocates into carpal tunnel
Space of Poirier
ANSWERS: ligament free area at Capitolunate space
TFCC
ANSWERS: primary soft tissue stabilizer for DRUJ and ulnocarpal joints
Ulnocarpal stress test
ANSWERS: axial load on the wrist in UD then passively perform
pronation/supination
