Hav

Front 1

DASA

Back 1

-Angle between bisection of PP shaft and perpendicular to cartilage of the PP base

Front 2

PASA

Back 2

-angle between lateral and medial margins of articular cartilage of mt head and base of pp

Front 3

lateral release

Back 3

-release conjoined adductor hallucis tendon
-release fibular sesamoid ligament
-Tenotomy lateral head of FHB
-Excise fibular sesamoid

Front 4

Metatarsus adductus angle

Back 4

-angle between bisection of 2nd MT and bisection of lesser tarsus (ant. first cuneiform, posterior navicular, ant/post cuboid)
-Tells you whether the FF is in rectus or adducted in reference to the RF
-Normal is <15 degrees
-Increased angle=more progressive HAV and will need aggressive procedure to correct
-Correction=move osteotomy proximal if greater than 15

Front 5

How do you calculate true im angle?

Back 5

True IM angle= measured IM angle + (MAA-15)

Front 6

MT protrusion

Back 6

-Difference in mm b/w lengths of 1st and 2nd MT
-positive value = longer 1st MT
-Negative value=longer 2nd MT
-Value= +/- 2 mm
-Correction if short=do opening osteotomy and stick in bone graft

Front 7

McBride

Back 7

Which procedure do you take off the bump, do a lateral release, fibular sesmoidectomy and transfer the adductor tendon medial side of PP

Front 8

Silver

Back 8

which CTB procedure do you take off the bump and do a lateral release, release fibular sesamoid

Front 9

Distal Akin

Back 9

Which procedure is indicated when you have high hallux interphalangeus angle?
-It is a closing wedge osteotomy performed 3/4 cm from IPJ on the proximal phalanx of the hallux

Front 10

Oblique/spiral Akin

Back 10

Which procedure is indicated for hallux interphalangeus and DASA at the same time?
-Performed 3/4 cm from MPJ on the proximal phalanx of the hallux, goes all the way up the shaft instead of transverse.

Front 11

Proximal Akin

Back 11

Which procedure is indicated High DASA performed 3/4 cm from MPJ on the proximal phalanx of the hallux

Front 12

Austin osteotomy

Back 12

Which head osteotomy procedure is a V-osteotomy w/ apex located at mid point of MT head.
-Corrects IM angle

Front 13

Youngswick

Back 13

Which austin modification do you add the resection of additional rectangle of bone from dorsal wing; two cuts instead of one
-it will PF and shorten first ray and correct IM angle***

Front 14

Bicorrectional austin

Back 14

Austin+ pie taken out dorsally
-corrects pasa and IM

Front 15

Kalish long dorsal arm austin mod

Back 15

-55 degree angle
-long dorsal arm
-reduces larger IM angle

Front 16

Step Defect

Back 16

-When you move the head over after a austin head osteotomy and shave and smooth if after is called....

Front 17

Reverdin

Back 17

-wedge cut, 1 is parallel to articular cartilage and other is perpendicular to long axis of MT
-corrects PASA
-complication=maybe get adhesion of sesamoids to MT or callus or dec ROM

Front 18

Reverdin-Green

Back 18

Reverdin with a transverse plantar shelf to avoid interruption of sesamoinds
-Corrects PASA

Front 19

Reverdin-Laird

Back 19

Reverdin, shelf intact, but breaks the lateral cortex and shifts the head over
-Corrects PASA and some IM

Front 20

Scarf

Back 20

"Z" shaft osteotomy
-corrects IM

Front 21

Vogler

Back 21

-Shaft osteotomy that can swivle and reduce IM and PASA
-not a long arm austin!!!

Front 22

Loison-balacescu

Back 22

-transverse closing base wedge osteotomy (CBWO) about a cm from met-cuneiform joint
-medial hinge intact w/ goal to make IM zero
-used for higher IM angles (eg high teens and 20)

Front 23

Juvara

Back 23

-oblique closing base wedge osteotomy (CBWO)
-medial hinge intact
-corrects IM

Front 24

Lapidus

Back 24

-1st met and cuneiform joint arthrodesis
-Stabilizes entire medial column and can be a permanent bunion correction
-Have to resect all the cartilage on both sides of the joint
-Good for juvenile HAV

Front 25

Logroscino

Back 25

Reverdin plus a loison balacescu

-corrects pasa and IM

Front 26

Trethowan

Back 26
