Alignment
If the foot is to outset in bench alignment, where is the heel in bench alignment
On the bench.
What is an ertle procedure?
A bone bridge is placed between the tibia and fibula.
Name 3 pressure tolerant areas.
MPT, pretibials, gastroc, fibular shaft, medial tibial flare
What does blanching mean when a socket is on?
Too much pressure
What's the difference between energy storing and dynamic response feet?
They are the same!
Having the foot inset in bench alignment results in what at the foot at midstance?
Foot being on the lateral border
What is the difference between myoplasty and myodesis?
Myoplasty is when muscle is attached to muscle. Myodesis is when muscle is attached to bone.
Name 3 pressure intolerant areas
Fib head, tibial crest, distal tibia and fibula, and distal end of the limb
What does redness when a socket is on mean?
Not enough contact/pressure
What type of foot is appropriate for a K1 patient?
SACH (Solid Ankle Cushion Heel)
lateral proximal and medial distal
What are some pros and cons of soft dressings?
Pros:
- aids in venous return, reduces edema, decreases pain, desensitizes residual limb, one size fits all
Cons:
- donning and doffing may be difficult for the patient and donning may be inconsistent
What is the primary weight bearing surface in a PTB socket?
MPT
How would you reduce localized pressure
Heat relief/padding (depends on location)
What K level(s) can receive an energy storing foot?
K3 and K4
Patient is experiencing pressure at the following: Proximal posterior, distal anterior. How is this socket aligned?
Too much socket flexion
What are some pros and cons of rigid dressings?
Pros:
- excellent edema control, excellent limb protection, limb desensitization, pain management, may permit early loading, aids in limb shaping
Cons:
- non-removable rigid dressings do not permit dressing change or wound inspection
What nerve is distal to the fibular head?
Peroneal nerve
How would you reduce globalized pressure?
take socks off
K0: non ambulatory
K1: transfers, household ambulator
K2: community ambulator, single cadence
K3: variable cadence, utilization beyond locomotion
K4: highly active, child, utilization exceeds basic skills
Why do we flex the socket in bench alignment?
puts functional muscles under stretch
How would you reduce the risk of a knee flex ion contracture post-op?
Encourage proper positioning at rest (knee in extension) and maintain regular exercise program on major muscle groups
Which hamstring depression is larger: medial or lateral? Why?
Medial. There are two muscles (Semitendinosus and semimebranosus) that insert medially as opposed to one muscle (biceps femoris) that inserts laterally.
What socket style creates the most stability?
Joint and thigh lacer
Name the Rockers!
1st: Initial contact to foot flat
2nd: Foot flat to vertical tibia
3rd: Vertical tibia to heel rise
4th: Heel rise to toe off
