Transtibial Suspension Options Flashcards
Some third-party reimbursement policies do not routinely permit the use of ___ and must therefore be taken to no consideration when making suspension recommendations for a prosthesis.
Gel liners and locking mechanisms
The cuff tabs for the supracondylar cuff are connected to the medial and lateral walls of the
thickest at a point ____ mm PROXIMAL to the MPT and ____ mm POSTERIOR to a vertical line bisecting the anterior and posterior aspect of the socket.
12 and 12
Prosthetic suspension sleeves when constructed of heavy duty neoprene, provide sagittal and coronal stability.
False
What is the purpose of the posterior “check strap” of the joints and corset suspension?
To prevent noise and joint wear
Transtibial suspension recommendations are based upon:
- residual limb condition
- knee joint stability
- patients abilities and activities
- insurance coverage
The standard starting place for PTB attachment point location is ___ and ___ to the sagittal midline of the socket at the level of the patella tendon “bar”.
1/2” posterior and 1/2” superior
A correctly placed cuff strap will suspend the prosthesis:
Over the patella
When proper attachment points are located for the cuff suspension the tabs will:
Maintain tension over a range of 60 degrees of knee flexion and will relax to allow the residual limb to withdraw from the socket with knee flexed 90 degrees
Under what conditions would you recommend a suspension belt for a BK prosthesis?
For a temporary PTB needing easy adjustment
What is the one major problem many patients have with the suspension sleeve prosthesis?
Heat and perspiration build up
Which of the following are characteristics of the PTB-SC prosthesis with removable wedge?
Hard socket low over patella with medial wedge
