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

see pics
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!!!!!!

Components of Transtibial Prothesis:
4:
- Socket + Interface
- Suspension Mechanism
- Shank (or pylon)
- Prosthetic foot
Components of Transtibial Prothesis:
Socket + Interface
-
Socket
- Where RL is housed (what the limb actually goes into)
-
Interface
- Anything that goes bw RL and socket
- ex. cotton ply (sock)
- Anything that goes bw RL and socket
Components of Transtibial Prothesis:
Suspension Mechanism
ANY system that secures RL comfortably in socket
keeps it in there snug
Components of Transtibial Prothesis:
Shank or pylon
The metal piece**
Component connecting socket and foot
Components of Transtibial Prothesis:
All components together
see pics
Transtibial Prosthetic Socket Interfaces:
Hard Socket
ADV’s vs Disadv’s
-
ADV’S
- Just the socket
- Intimate fit→ less shear
- No liners needed
- easy clean, less bacteria
-
Disadv’s
- unless PERFECT, hard to modify as socket changes
-
NOT approp for fragile skin as RL changes
- bc its only skin on socket***
Transtibial Prosthetic Socket Interfaces:
Socks
aka “Plys”
1 ply=thinnest and then they inc from there ***
ADV’s vs. Disadv’s
-
ADV’s
- cushion forces to RL
- **Easy to accommodate to changing limb vol.
- wicks moist. away from skin
-
Disadv’s
- cosmetic
- wrinkles**
- uncomfy in warm weather
- clean often
Transtibial Prosthetic Socket Interfaces:
Socks
*NOTE about Socks!!!
- Some pts use nylon sheath bw socket and prosthetic sock
- Prosthetist often design hard socket to accommodate to 3 ply as a baseline to preserve intimacy while still providing cushion
Shrinkers****
For when?
Used when prosthetic NOT ON!
Transtibial Prosthetic Socket Interfaces:
SOFT LINER
ADV’S vs. Disadv’s
*MOST COMMON SOCKET INTERFACE USED TODAY!
-
ADV’S
- best for bony prominences
- easy adjust
-
Cushions RL and protects from ext. forces
- best for function
-
Disadv’s
- absorbs sweat→ hard to clean
- liners compress w/ rep’d loading
- inc bulk of prosth.
- high lvl/sports this decs somatosensory input→ not preferred
Transtibial Prosthetic Socket Interfaces:
Soft Liner
*NOTES
- MOST COMMON socket interface used today
- Usually amp. will use sheath, then approp. ply, then soft liner
Transtibial Prosthetic Socket Interfaces:
Roll-on Liners*
*Rubber or polyeurothane
*think thing that lock pin hangs off of
ADV’s vs. Disadv’s
-
ADV’s
- disperse forces during gait (esp shearing)
- good for fragile skin/breakdown
- accommodates for minor changes in volume w/out adj’s
-
Disadv’s
- rxn to liner material→ dermatitis, bact. infxs, follicular irrit.
- strength+dexterity in UEs to don
- incd care to clean
Transtibial Prosthetic Socket Interfaces:
Roll-on Liners
*NOTE: rxn to liner causing blistering, rash→ dermatitis, bact. infxs, follic. irritation
Caused by?
Caused by change in skin tension @ the interface and alleviated often by some non-water soluble lube
Suspension Systems
What is it?
- Anything holding prosthetic limb onto anatomical limb
Suspension Systems
2 types of Pre-molded
- Patellar tendon
- Supracondylar suspension
Transtibial Prosthetic Suspension Systems:
Sleeve Suspension
Explain it
- Goes on outside*
- Placed distally around shank of prosthesis and proximally rolled upward over several inches of skin as the inner surf. grabs skin
- Uses friction and negative pressure to hold prosth.
Transtibial Prosthetic Suspension Systems:
Sleeve Suspension
*the one that goes on outside
ADV’s vs. Disadv’s
-
ADV’s
- Thinner→ more cosmetic
- waterproof
- easy to use
-
Disadv’s
- limtd durability→ tears/stretches
- retains heat
- skin irrit and sweating esp in hairy pts
Transtibial Prosthetic Suspension Systems:
Supracondylar
Explain it
- Captures femoral condyles to hold prosth.
- AKA PTB-SC (Patellar Tendon Bearing Supracondylar)
- where wt. is distributed on patella tendon
-
PTB-SCSP (same as above but also SupraPatellar)
- → high ant. wall added over patella w/ quad bar to help w/ suspension
Transtibial Prosthetic Suspension Systems:
Supracondylar
ADV’s vs. Disadv’s
-
ADV’s
- provides med/lat knee stability
- don/doff is easy
-
Disadv’s
- NOT effective when clear def. of femoral condyles not present
- muscular or obese
- prox high walls obv. thru clothes
- PTB-SCSP incs patella compression
- NOT effective when clear def. of femoral condyles not present
Transtibial Prosthetic Suspension Systems:
Cuff Suspension
Explain it
- Leather webbing in shape of X attached distally to prosth. capturing femoral condyles proximally
- “X” attached just sup. to patella and wraps posteriorly to hook w/ buckle
- Success of susp. related to pos. of attachment on the prosth.
- Attach. points should be posterior to the center of the socket so the line of pull falls posteriorly @ the proximal portion of the patella
Transtibial Prosthetic Suspension Systems:
Cuff Suspension
ADV’s vs. Disadv’s
-
ADV’s
- Pts of attach easily modified to control hyperEXT
- don/doff easy
-
Disadv’s
- impinge soft tissue→ obese not good option
- compromised circ. if belt too tight
- diff. sitting/kneeling
Transtibial Prosthetic Suspension Systems:
Roll-on Suction w/ Pin-Lock
Explain
- 2 Components
- Pliable silicone polymer sleeve (1-9mm thick)
- Short peg or pin
- Pin locks into lock. mech. in base of prosth. providing friction bw sleeve and skin suspending prosth.
Transtibial Prosthetic Suspension Systems:
Roll-on Suction w/ Pin-Lock
ADV’s vs. Disadv’s
-
ADV’s
- incd limb aware.
- decd shearing forces on skin→ excellent option for fragile skin proximally
- audible click from pin***
-
Disadv’s
- $$$
- tear/stretch
- sleeves must be cleaned
- skin irrit, heat
- incd shearing distally due to fixed pin
- liners can get stuck in pin-lock
- pin can be locked in crooked
