HIGH YIELD Flashcards
what are the complications?
medial deviation of the first metatarsal
lateral deviation/rotation of the hallux
medial prominence with/without soft tissue edema
increase mech advantage of what muscle?
adductus hallucis
these muscles become less than linear than the first ray
EDL and FHL
loss of mech adv of which peroneus muscle?
peroneus longus
which ray is unstable?
first ray
attenuation of medial joint structures occurs, T/F?
true
foot types that cause HAV complications?
underlying conditions?
pes planus
equinus
*RA, ligamentous laxity, marfans syndrome
gastrocnemius/gastroc-soleus equinus
rigid/flexible pes planus
forefoot varus
met primus elevatus
short first metatarsal
hyper mobility
causes of what type of complications?
HAV complications
how do HAV complications present?
medial 1st metatarsal pain on palpation
pain in shoegear
overlapping 2nd digit
medial dorsal cutaneous nerve neuritis
erythema/bursa to medial prominence
pain under 2nd MTP transfer
what does the physical exam look for?
valgus/frontal plane rotation of hallux
1st ray hypermobility
joint tracking
extensor hallucis longus contracture
lesser digit contracture
flexible/rigid flatfoot
hallux abductus angles?
IM angle?
tibial sesamoid position?
0-16 degrees
0-8 degrees
1-3
hallux valgus surgery complications is dependent on?
*rate of complications is dependent on?
inherent stability of the osteotomy
type of fixation
anatomical location of osteotomy
underlying conditions
*surgeons expertise, ability to perform the procedure, knowledge
recurrent deformity percent?
5-20% and presents as recurrent bunion pain
intrinsic causes: unstable osteotomy site, displacement sesamoidal apparatus, failure to release lateral STs, inadequate reconstruction
major recurrent deformity?
scarf can have dorsal displacement secondary to troughing
metatarsalgia
