L2:P&O: Post-Sx and Early Rehab Phase Flashcards
OBJECTIVES:
Ray amputations include:
Usually 1st and 5th
*breakdown from GRFs
Midfoot amputations
Chopart
Lisfranc (TMT Jt.)
Hindfoot (rearfoot) amputations
Syme (most common and easiest to fit prosthesis)
Pirogoff
Boyd
Other partial foot and Syme amps
Digit amps
Metatarsal amps
Surgeons and prosthetists prefer Syme amputation due to what?
Ease of sx and fitting for prosthesis
Surgeons prefer Syme, BUT better function reported for which amps?
Lisfranc
Chopart
One complication of any rearfoot sx is _________
Muscular imbalances due to severed DFs unable to oppose intact triceps surae
NOTE: Triceps surae is gastroc/soleus complex
Partial foot and Symes amps
preservation of these 2 things is crucial
Ankle jt and heel
Challenging for a proper fit prosthesis
Length and shape of RL
MORE RL length====
More surf area==less pressure==less skin breakdown
Usually partial foot and Symes amps are able to WB w/out prosthesis
T/F??
TRUE!!!
*prosthetic protects skin and allows for norm gait mech’s
Partial foot and Symes amps
Clinical presentation
DECd what?
DEC strength in lower leg mm’s
DEC surf area→ proprio loss=balance deficits
DECd sensation→ severed nerves
DECd anterior lever arm→ no anatomical rockers remain
PRIMARY GOAL post-sx w/ all partial foot and Syme amps
Preservation of remaining foot
SECONDARY GOAL post-sx all partial and Syme amps
Maximize gait quality and metabolic efficiency
Partial foot and Symes amps
Gait implications @ IC:
may or may not be heel first gait depending on sx
*if can-→ emphasize heel strike if still have calcaneus
Partial foot and Symes amps
Gait implications @ IC→MSt
DECd shock absorb due to DECd ecc quad strength
- pt compensates by keeping knee in EXT (now GRF remains ant. to knee jt)
- INC likely knee pain/breakdown
Partial foot and Symes amps
Gait implications @ Mst-TSt
Early heel rise (prop to length of forefoot)
GRF moves more quickly behind knee jt→ INC need for quad activity
Partial foot and Symes amps gait implications
IC>MSt>TSt
see pics
Partial foot and Symes amps
Gait implications @ TSt→PSw
W/out prosthesis or toe filler to lengthen foot, active lifting/swinging of foot vs passive rollover and energy storing in triceps surae
Pot for skin breakdown here→ shear forces
Partial foot and Symes amps
Gait implications @ ISw→TSw
UNAFFECTED unless limb too long (prosthesis too long or poor fit)
Partial foot and Symes amps
Temporospatial changes
Q&A
- DECd contralat step length
- Foot down faster
- DECd velocity
- Decd step length
- INC width BOS
- Balance
- INC DS time
- Stability
- INCd energy expend.
- less momentum
- TIP: use UBE***
Partial foot and Symes amps
Gait implications
Normal lever arm vs reduced lever arm and step length results

Partial foot and Symes amps
Prosthetic Mgmt
More proximal amputation (foot/toes)===MORE LIKELY
supramalleolar containment needed (support)
Partial foot and Symes amps
Prosthetic Mgmt
Length and flex of the _______ affect the _______ which directly controls __________
Length and flex of the forefoot affect the anterior lever arm which directly controls foot and ankle motion
2 Main Goals of foot prosthesis and/or shoes:
- Anterior support for missing parts of foot→ controlled fulcrum for third rocker of gait
- normal step length and gait symm.
- Min pressure @ ampd distal end
Toe fillers and modified shoes:
Rocker bottoms assist w/ what?
Rollover and DEC plantar surface pressure
*challenge providing enough lever arm support w/out add. pressure to RL
Custom shoe inserts and toe fillers
- Typ w/ hallux or first ray amps
- Goal: provide flex anterior extension (like Great toe ext.)
- Improve 3rd rocker during TSt-PSw
- supports medial arch and normalize GRFs
- spacers
s
Cosmetic Slippers
- Transmetatarsal amps
- little biomech. advantages
- mostly cosmetic
ideal for swimming*
Prosthetic boots
- Gaining pop→ Transmet and Lisfranc and distal amps
- Greater prox encompassment to reduce distal motion and inc control usually w/ hinged ankle mech.
Syme’s Amps aka
Tibiotarsal amputation
Symes Amp
What is it?
Disarticulation of the talocrural joint w/ the forefoot completely removed
- Calcaneal fat pad preserved and anchored to distal tibia
- ==> limtd distal WB w/out prosthesis
2 Drawbacks to Symes Amps
- Migration of distal heel pad
- usually avoid WB until receive prosthesis
- Poor cosmesis→ may shave malleoli to improve
Syme’s Amps
Prosthetic Mgmt
Understand there are diff options
- Walking cast
- Canadian Symes
- drawback: posterior panel
- Medial opening Symes
- Most commonly used Symes prosthesis
- Sleeve suspension (stovepipe) Symes
- slides into flex insert
Most commonly used Symes prosthesis
Medial Opening
Bulky, stronger prosthesis chosen for obese or very heavy duty user
Sleeve suspension (stovepipe) Symes
NOTE about all Symes prostheses
All designed for total contact to improve comfort and dec chance of breakdown
Which is the primary goal of the surgeon to preserver whenever possible?
Talocrural Joint!!!!!!
