What type of procedure is a Reverdin and all of its modifications?
metatarsal head medial wedge osteotomy
What is a Reverdin-Green modification?
protects the sesamoids
For an increased PASA and moderate increased IMA (12-15) what procedures would you consider?
Bicorrectional Austin, Mitchell, Hohmann, Wilson
What is an Austin procedure?
chevron cut at 60 degree angle in the met head; it corrects moderate IMA (12-15)
What is a Mitchell procedure?
for moderate IMA (12-15); allows for lateral translation of the met head and preserves the lateral cortex
What is a Hohmann procedure?
for moderate IMA (12-15); through and through medial wedge which will shift met head lateral and plantarflex
What is a Wilson procedure?
for moderate IMA (12-15); it is a oblique cut distal-medial to proximal-lateral; it WILL SHORTEN the first met
For an increased PASA and severe IMA (>15), which procedures would you consider?
Logroscino (CWBO + Reverdin), Lapidus + Reverdin
What is a Logroscino procedure?
For increased PASA and severe IMA (>15); CWBO + Reverdin
For moderately increased IMA (12-15), which procedures would you consider?
Austin, Kalish, Mitchell, Hohmann, Wilson, Scarf
What is a Kalish procedure?
For moderate increased IMA (12-15); chevron osteotomy with a long dorsal arm; angle is 55
What is a closing wedge base osteotomy?
For severe IMA (>15)
What is an opening wedge base osteotomy?
For severe IMA (>15); you add in a wedge
What is the Vogler (offset V) procedure?
For severe IMA (>15); similar to Austin but the angle is at 40 degrees
What is a Ludloff procedure?
For severe IMA (>15); shaft procedure with a cut proximal-dorsal to distal-plantar
What is the Mau procedure?
For severe IMA (>15); shaft procedure incline angle with a cut proximal-plantar to distal-dorsal
What is a Lapidus procedure?
For severe IMA (>15); arthrodesis of 1st met and medial cuneiform
What is a cheilectomy?
removes portion of metatarsal head to relieve hallux limitus
What is a Youngswick procedure?
for mild bunions or hallux limitus; modified Austin but an extra dorsal wedge is removed to allow plantarflexion of 1st ray
What percent of shock is absorbed by the heel fat pad?
25%
In plantar fasciitis, what is the underlying cause?
plantar fascia is thickened with tenocytes bc tissue is trying to repair itself from all the microtears
In plantar fasciitis, as tissue is trying to adapt what a long term effect on the calcaneus?
bone spur growing in the transverse plane (it is a secondary effect and not the main problem)
The radiograph for 3 view heel include which ones?
MO, lateral, and axial calcaneal view
You don’t want the DP view.
1st toe directed laterally in transverse plane
HAV angle = >12
Hallux Valgus
1st dtoe directed laterally in transverse plane + abduction in frontal plane
HAV angle = >12
Hallux Abducto Valgus
What is the primary motion of the 1st ray?
45 degrees in sagittal and frontal planes (DF, PF, Inversion, Eversion)
Which is more severe in the sense that there is a decreased ROM, structural or functional hallux limitus?
Structural bc both the OKC and CKC ROM <65
Which stage of Hallux Limitus would you rate if you observed crepitus?
At least stage 3
For mild bunion procedures, what is the post-op course?
WBAT post op shoe 6-8 weeks. Then PT
For moderate to severe bunion procedures, what is the post-op course?
NWB
A positive Veilleux’s sign indicates what?
sciatica or radiculopathy
The gastroc, soleus are major _____ during gait.
accelerators
The tib anterior is a major _____ during gait.
decelerator
During heel strike, what is the specific role of the criss-cross between PT and peroneus longus in acceleration?
They are concentric plantarflexing the ankle in the sagittal plane
During heel strike, what is the specific role of the criss-cross between PT and peroneus longus in decceleration?
(F*ck The Desk)
They are concentric stabilizer the ankle in the frontal & transverse plane
Be able to identify plantar fasciitis on an ultrasound.
If fascia is thicker than __mm = plantar fasciitis
3
What is verruca plantaris?
plantar warts
What’s the medical terminology for ingrown toenail?
onychocryptosis
What are the differences between avulsion and matrixectomy for an ingrown toenail?
Avulsion → removal of some or all nail plate → use tools
Matrixectomy → permanent destruction of nail matrix → prevent nail growth → using chemical
Can be done as partial or total matrixectomy
Functional orthotics will correct what type of foot problem?
Restore abnormal biomechanic and function of joint
Accommodative orthotics will correct what type of foot problem?
Reduce pressure or strain
What is the THA for DP WB view?
15 degrees
What is the THA for MO WB view? How does pt position the foot?
0 degrees; pt rotates foot 45 degrees with the plate
What angle is used to diagnose foot cavus vs planus on radiograph?
Meary’s Angle
Normal: 0 degree
Pes cavus: > 4 degrees → convex upward
Pes planus:< -4 degrees → convex downward
What are the mechanics of a claw toe?
flexed DIPJ, flexed PIPJ, extended MTPJ
What are the mechanics of a hammertoe?
extended DIPJ, flexed PIPJ, extended MTPJ
What are the mechanics of a malletoe?
flexed DIPJ
What is the difference between apophysis and exostosis?
apophysis is where a tendon or ligament attaches
exostosis is a bony outgrowth from an existing bone
Describe the wing and sling apparatus.
the sling wraps around the metatarsal w/ the EDL tendon superior and plantar plate inferior
the wing extends from the lumbrical
What is a Type I Fallet classification?
enlarged lateral met head
What is a Type II Fallet classification?
lateral bowing
What is a Type III Fallet classification?
increased mini IM angle (most common)
What is a Type IV Fallet classification?
combined (not common)
What is the most common etiology for tailor’s bunion?
forefoot varus
What is the average 4th IMA for symptomatic feet regarding tailor bunion?
9
What is the only wedge osteotomy performed on the 5th met that is a lateral opening wedge?
