Symes Amputation and Prosthetic Management Flashcards
A satisfactory end bearing Syme prosthesis should have which of the following characteristics:
- suspension during swing phase
- lengthening of the limb to adjust for loss of the talus and calcaneus
- transmission of body loads
- ability to supply foot and ankle function
Indications for an end bearing Syme prosthesis depends primarily on the physical characteristics of the residual limb.
True
Function tests by Dr. Jacquelin Perry have shown the Syme amputee to have greater stride length, faster cadence, greater velocity, and less energy consumption than patients with more proximal amputations.
True
Stabilization against rotary forces about the long axis in a Syme socket is obtained by triangular (three point) stabilization against the flares of the tibia and a flattening across the posterior portion of the
Gastrocnemius
The ____ type of design for a Syme prosthesis offers the most strength in construction.
Closed double wall (tubular)
Why should the prosthetist use a standard PTB proximal socket design in the Syme prosthesis?
To unload the distal residual limb.
Several suspension options exist for the Syme prosthesis including:
- leather sockets
- medial opening
- posterior opening
- supracondylar cuff suspension
Dr. Syme listed “smaller risk to life” as an advantage of the Syme amputation ankle disarticulation over the transtibial amputation.
True
The Syme amputation includes the removal of the distal tips of the medial and lateral malleoli as well as the fibula.
False
Dr. Perry has shown oxygen consumption to be lower and velocity to be higher for the Syme amputee as compared to the transtibial or transfemoral amputee
True
The Syme amputation may be fully weight bearing and use various forms of self suspension methods
True
Axial rotational control of the prosthesis can be provided by:
- proximal PTB shape of the socket
- flattening the posterior brim to increase triangulation
