Greater than 7 inches
What is a symes amputation?
Removal of the tibia and fibula above the malleoli and covering it with the heel pad.
What is an ankle disarticulation?
Does not cut through the periosteum but may adjust the pointiness of the tibia and fibula and wrap the heel pad around it.
What does PTB stand for
Patellar Tendon Bearing
What does TSB stand for?
Total Surface bearing
What are the pressure intolerant areas of a PTB socket?
Distal end of fib and tib
Medial side of Tibial plateau
What are the pressure tolerant areas of a PTB?
The Patellar tendon bar
The length of the fibula and tibia
What shape does the PTB create?
A triangular shape
What are the indication for a PTB?
Selective Hot Spots
Where are the pressures during initial contact?
Has greater Distal anterior pressure
Greater Proximal posterior pressure
What are the pressures during Loading Response?
less pressure distally
What are the pressures during Terminal Stance?
More pressure proximal anterior and distal posterior
What should be the main goal of the socket?
Distribute pressures from intolerant areas to tolerant areas
