Plantar fasciitis Flashcards
where does micro tearing occur with PF
calcaneal attachments
where does plantar fascia attach to
medial process of calcaneal tuberosity
merges into plantar surfaces of MTP jts and flexor tendon sheaths
plantar fascia functions as a passive bowstring during what phase of the gait cycle
mid-stance phase - approximating the calcaneus and medial longitudinal arch
what is the fat pad that covers the plantar surface held in place by
cutaneous septa
what is the fat pad designed to do
cushion calcaneus during initial contact phase of gait cycle
what muscles control shock absorption when walking and running
soleus
gatsroc
plantar fascia and gastroc/soleus basically share same attachment point @ calcaneus - if these muscles are short, what do they do
pull on the plantar fascia –> leading to micro-tearing near calcaneal attachments
causes of P.F
overuse (most common)
poor technique
running on hard surfaces
prolonged standing and activities that require ankle PF and ext of MTP joints like running or dancing
predisposing factors
poor biomechanics (excessive pro or sup of subtalar jt)
excessive ER of hip when walking
short/tight gastroc/soleus which predispose foot to pronation
improper footwear
weight gain
hallmark signs of P.F
pain in morning w first few steps after non weight bearing
pain upon weight bearing near anterior-inferior surface of calcaneus
palpation of anteromedial aspect of plantar surface of calcaneus
pes cavus or planus, achilles tendinitis can also be present with P.F?
yes
where may swelling be observed with P.F
along medial longitudinal arch
when would pain be reported worse during gait cycle
pre-swing (toe off) phase
testing for P.F
AROM/PROM ext of MTP joints
length tests for gastrocs/soleus reveal shortness
AROM hopping on one foot
weak intrinsic foot mms can be present (resist toe flexion)
entrapment of the posterior tibial nerve in the tarsal tunnel at medial malleolus is called
tarsal tunnel syndrome
sharp pain, paresthesia in medial arch, heel and occasionally toes
