structural metatarsalgiaSTATIC abnormality of the foot resulting in forefoot pain
egs of structural metatarsalgialong metatarsal, brachymetatarsia, plantarflexed metatarsal,
tx for neuromaextra depth shoe
bony problem=structural
Lengthening the 4th MT usually in surgeryBrachymetatarsia
Functional EtiologyPathological pronation with hypermobility, equinus, LLD, hammertoe
evaluate LLD byscanogram
complication of compensating cavus footleads to hammer toe which a complication of the fat pad displaced anteriorly
check for equinussilverskiold test
Differential diagnosis: neuroma vs verrucaeNeuroma-check by dropping in some lidocain, verrucae-do a biopsy!
transfer calluscallus moves from place you did surgery but then ends up coming back under another met head
goal of surgical managementto redistribut the weight of the forefoot to all the central metatarsals to bear equal weight
Where are surgical osteotomies made, anatomical or surgical neck?surgical neck
surgical neck location to anatomical necksurgical neck is proximal to anatomical neck

complications of duVries condylectomyfloating toe and transfer callus
DuVries condylectomy indicationsosteopenic bone, DM ulcer
Girdlestone-Taylorprocedure to prevent floating toe
implant is done in a non weightbearing device
V shape osteotomy in the MT head with apex proximal to condylesJacoby "V" osteotomy
complications of jacobytransfer calluses, floating toe
transfer callus will happen if elevation is greater than ___ mm4-5mm
Oblique cut through a dorsal approach and you slide the inferior fragment back and then snip the dorsal nub of bone offWeil
indications for Weillong MT and subluxed jt

Indication for Jacoby v Weil v Duvries?-Jacoby-plantarflexed met, raise it up,-Weil-shortens met, subluxed phalanx on met.Duvries-condylectomy-osteopenia, ulcers
Goals of the Weil osteotomy. Decrease ____, altered load transmission by ___ and ___, decrease MPJ ____Decrease metatarsalgia(pain in the ball of the foot), altered load transmission by plantarflexing and shortening, and decrease MPJ subluxation

Which is NOT the differential diagnosis for metatarsalgia of the central metatarsals? a. neuroma b. freiber's infarction c. HAV d. stress fractureHAV
Following a Weil osteotomy, how soon can a patient go weightbearing in a post-op shoe? a. 1 day b. 3 days c. 7 days d 14 days1 day
Which of the following metatarsal procedures is done on the proximal aspect of the metatarsal? a. weil b schwartz c. giannestras d. DFWO( dorsiflexory wedge osteotomy)DFWO
one method of pathogenesis that leads to rupture dislocation of the lesser MTP-high functional stresses of ____ and ___ of the MTP can lead to attenuation or _____ which may then lead to subluxation or ____High functional stresses of weightbearing and repetitive hyperextension of the MTP can lead to attenuation or rupture of the plantar plate which may then lead to subluxation or dislocation of the toe.
