plantar fascia
Lisfranc injury etiology
dorsum of foot rolls further forward (snowboarding, football, equestrian sports)
S&S Lisfranc injury
- inability to weight bear
- localized swelling & tenderness
Pes Planus etiology
- poor biomechanics
- wearing tight shoes
- trauma
- overweight
- excess exercise pressure on arch
S&S Pes Planus
- pain
- weakness or fatigue in medial arch
- flattened appearance of arch
Management - Pes planus
- leave it alone is not causing an issue
- orthotics, arch taping if problems develop
Pes Cavus - etiology
- higher arch than normal
- associated with excessive supination
- accentuated high medial longitudinal arch
S&S pes cavus
- poor shock absorption, resulting in metatarsalgia
- foot pain
- clawed or hammer toes
- associated with tight achilles and plantar fascia
- heavy callus development on ball and heel of foot
pes cavus - management
- leave it alone if not causing an issue
- orthotics (?)
- stretch achilles and plantar fascia
plantar fasciitis - etiology
- tight heel cord
- cavus foot or hyperpronation
- changes in footwear or training surfaces
- excessive training
S&S plantar fasciitis
- point tenderness medial heel/ medial arch
- pain with forceable dorsiflexion
- first step pain
management of plantar fasciitis
- orthoses/heel cup
- arch taping/night splint
- massage and vigorous stretching
metatarsal stress fractures - etiology
- common in running and jumping sports
- most frequent in 2nd MT “March fracture”
- associated w/ increase in training, change in training surfaces
- inappropriate footwear
- flat feet & bunions
S&S MT stress fractures
- over 2-3 weeks of dull ache during exercise
- progressing from diffuse to localized pain at rest
MT stress fracture - management
- limit WB activity & cross train with NWB activities
- determine source of injury
- gradual RTA
bunion (hallux valgus deformity) - etiology
- lateral deviation of hallux and exostosis of 1st MT head
- great toe shifts towards 2nd toe
- associated with increase pronation, footwear, genetics
- bunionette (Tailor’s bunion) impacts 5th metatarsophalangeal joint - causes angulation towards 4th tow
bunion S&S
- tenderness, swelling, and enlargement of joint initially, resulting in angulation
- walking becomes painful
bunion management
- wear correct fitting shoes
- appropriate orthotics
- pad over 1st MT head
- tape splint between 1st and 2nd toe
- engage in foot ex for flexor and extensor mm
- bunionectomy may be necessary q
sesamoiditis - etiology
- caused by repetitive hyperextension of the great toe or landing on 1st MTP
- common in dancing and b ball
S&S sesamoiditis
- pain and tenderness under great toe
especially during push off
management of sesamoiditis
- treat with orthotics devices (MT pads, arch supports)
- decrease activity to allow inflammation to subside
Metatarsalgia - etiology
- pain in ball of foot
- tight gastroc-soleus complex or fallen arches; increase callus formation
S&S metatarsalgia
- transverse arch flattened
- pain w/ WB activities
- cavus foot may also cause problems
metatarsalgia - management
- MT pad
- stretching heel cord and strengthening intrinsic foot mm
Morton’s neuroma - etiology
- interdigital nerve irritation d/t tumor or nerve entrapment
- caused by excessive pronation; weak feet
S&S - morton’s neuroma
- burning parasthesia and severe intermittent pain in forefoot
- notably between 3rd and 4th MT heads
- pain relieved with non-wbing
- toe hyperextension increases symptoms
management - morton’s neuroma
- must rule out stress fracture
- MT padding
- shoes with wider toe box
- surgical excision may be required
sprained toe - etiology
- generally caused by kicking non-yielding object
- hyperrextension of 1st MTP = turf toe
S&S Sprained toe
- pain & immediate swelling
- discoloration occuring within 1-2 days
- stubbed toe stiffness and residual pain will last several weeks
management - sprained toe
- POLICE
- buddy taping
- turf toe taping
- begin wbing as tolerable
etiology - subungual hematoma
- direct pressure, dropping an object on toe
- kicking another object
- repetitive shear force on toenail
- improperly fit shoes, running downhill
S&S subungual hematoma
- accumulation of blood underneath toenail, extreme pain, loss of nail
subungual hematoma - management
- RICE immediately to reduce pain and swelling
- relieve pressure within 12-24 hours (lance or drill nail) - must be sterile to prevent infection
etiology - ingrown toenail
- generally occurs in great toe
- results in lateral pressure from shoes
- poor nail trimming and repeated trauma
S&S ingrown toenail
- pain
- swelling & redness around irritated section
management of ingrown toenail
- conservative management includes soaking inflamed toe in warm water (20 min)
- place cotton under edge of nail to clear from skin
- if chronic, remove wedge of nail and apply antiseptic compress until inflammation resides
- physician may take more aggressive approach
ingrown toenail prevention
- properly fitting shoes and socks are essential
- weekly toenail trimming (cut straight across)
- leave nail long enough to clear skin
tinea pedis - etiology
- most common form of superficial fungal infection
- highly contagious
S&S tinea pedis
- extreme itching or soles of feet, between and on top of toes
- appears as dry scaling patch or inflammatory scaling red papules forming larger plaques
- may develop secondary infection from itching and bacteria
tinea pedis - management
- topic antifungal agents and good foot hygiene
blister - etiology
- result of a shearing force that produces a raised area that accumulates with fluid
blister S&S
- hot spot, sharp burning sensation, painful
- superficial area of skin raised with clear fluid
blister prevention
- use of dust or powder or lubricant to reduce friction
- 2 pairs of socks if feet are sensitive or perspire excessively
- appropriate shoes that are broken in
- pad hot spots
- lubricants
- management - see wound care lab
