ABFAS Forefoot Complete Exam Questions
With Correct Solutions
Kalish Vs Austin
Kalish 55o Austion 60
allows screws fixation
Youngswick
shorten and plantarflexes**for met elevatus
Distal metaphyseal JUVENILE osteotomies
Austin, offset v, reverdin, mitchell, wilson and peabody. Mitchell and wilson SE including shortening,
transfer lesions, elevatus, metatarsalgia
Reverdin --->do if theres a ton of lateral deviation of head cartilage=INCREASE PASA. fix with buried k
wires, absorbable pins, monofil wire. You can also do the reverdin in combo with logriscino (prox
osteotomy)=DOUBLE OSTEOTOMY
Bunion procedures if IM is 15+ in juvenile
Base procedure aka proximal metaphyseal osteotomy.
-closed or open base wedge, cresentic procedure, lapidus =goal to make first and 2nd mt parallel
without damaging the open physeal plate.
Where do you fix PASA vs DASA
Fix pasa with mt head osteotomy like REVERDIN=lat cortex intact proximal cut parallel to 1st mt and
distal cut parallel to articular surface
Fix DASA W/ proximal akin
FIxes PASA
"DROP like Atl"
DRATO
Reverdin
Offset V with rotation
Peabody
Austin biocorrectional
Postion of 1st MPTJ Fusion
neutral rotation of the hallux,
10-15 degrees of valgus
20-30 degrees of dorsiflexion in reference to the axis of the first metatarsal
the hallux nail should face upward with no frontal plane rotation, in alignment with the second digit
transversely, and just off of the weightbearing surface of a loading plate in the sagittal plane. There
are certain consequences that can occur if appropriate positioning is not performed. Too much
plantar flexion can cause an increase in stress to the hallux interphalangeal joint, and too much
dorsiflexion can make shoe fitting a challenge as well as cause less hallux purchase during gait until
late propulsion. Incorrect positioning in the transverse plane could lead to second digit irritation
laterally or shoe irritation medially, and frontal plane deviation can cause pain due to overloading of
the interphalangeal joint condy
, Suture material
Absorbable (e.g. Vicryl (polygalactin 910), chromic gut)
Degraded in tissue in less than 60 days
Traditionally used for closure of subcutaneous tissues
Non-absorbable (e.g. Ethilon (nylon), silk, Prolene (polypropylene)
Lasts longer than 60 days
Traditionally used for skin closure
Monofilament (e.g. Prolene (polypropylene), plain gut)
Made of one strand of material
Abs vs nonabs sutures
Multifilament (e.g. Vicryl Rapide (polygalactin 910), silk)
Made of multiple strands woven together in a braid
More friction when pulled through tissues, however this adds greater security to knots than
monofilament
Greater risk for inflammation and infection than monofilament (Masini 2011)
monofilament vs. multifilament
Natural (e.g. silk, chromic gut)
Made of organic materials
Traditionally more inflammatory than synthetic materials
Synthetic (e.g. Ethilon (nylon), Vicryl (polyglactin 910))
Made of laboratory manufactured material
Synthetic vs non synthetic sutures
it courses from medial mal to foot
innervates medial and dorsal foot
stops at: hallux
Saph nerve terminal branches
Lat calcaneal branch
lat dorsal cutaneous nerve
**suppiles lateral foot
Sural Nerve terminal branch
The superficial peroneal nerve or superior fibular nerve, innervates the peroneus longus and
peroneus brevis muscles and the skin over the antero-lateral aspect of the leg along with the greater
part of the dorsum of the foot (with the exception of the first web space, which is innervated by the
deep peroneal nerve).
Innervation of Superficial Peroneal nerve
Iv anesthetic, adrenal insuff
SE Etomidate
