The presentation covered several topics related to prosthetics including bilateral amputees, pediatric amputees, sports, and advanced techniques. For bilateral amputees, the most common risk factor for bilateral amputation is diabetes and important body parameters must be considered in limb design. Sports discussed included running, basketball, and more. For pediatric amputees, causes include congenital deficiencies and trauma, and special considerations are required for materials, fitting, education, and managing bone overgrowth during growth periods. Advanced techniques utilize CAD/CAM technology, 3D scanning, socket design software, and machining to create more accurate and durable prosthetics.

body parameters :
• Dimensions (e.g.,
length, density, and
mass)
•Segmental center of

•Whole-body center of
mass location
•Moment of inertia
(angular inertia)
How to design a limb for bilateral amputees?

9. Sports
Running
• Can use dynamic response foot to provide
push off, energy storage and release vertical s
hock absorption

10. Pediatric amputee
Many prosthetic principles used in treating adults can
apply to the treatment of children but most techniques used
with adult amputees must be downsized, sequenced in deg
ree of complexity, modified or completely altered to match t
he ever-changing needs of children.

11. Pediatric amputee
Causes
Prosthetic management
• Congenital Deficiencies :
Fibula hemi-Melia is the most
common in TTP.
• Emergency amputation : Due
to emergency problem such as
accident, gunshot, electrical
burn
• Elective amputation : Disease
or trauma include the Skin
graft, Partial foot amputation,
burns, revisions,
disarticulations, occasionally.
• Bone overgrowth
• Appropriate material
• Fitting
• Education and follow up

12. Pediatric amputee
Appropriate materials
Fitting
Education and follow up
Bone overgrowth can cause
painful and the prosthetist should to
pay attention about this , Make the
hard socket bigger than stump and
use more socks or thickness of soft
liner and another way , can put the
distal padding on distal end of socket
for prevent pressure and relief pain.
Materials and components should be
•Durable
•Simplify lengthening
•Switch out easily
•Very safety for children and parents
• For young children : difficult to tell how
they feel about the device due to difficult to
adjust alignment
• For old children is easier than young
children because they can tell how they
feel like or dislike about the device.
• CPO should to let the parents to observe
about the device outside the hospital and
PO should to educate patient and
arents about
How to apply, remove and care the
rosthesis
Examining the condition of the
esidual limb
And if the patient have to adjust
ength, reduce sock or have any
roblem about the device, Parents
hould contact to the CPO
ollow up :
Device generally will require growth
djustments by a prosthetist three or
our times per year.
Every 12 to 18 month during peak
rowing years, and perhaps every 1 to
years during adolescence

13. Prosthetic management
The difference between the pediatric amputee that caused by congenital and caused
by amputation is about mental status.
In congenital limb deficiencies, patient never have the limb but in the amputation
amputee, the patient limb is lost by amputation.
You have to concern about this !!
Bone overgrowth
Bone overgrowth can cause painful and the prosthetist should to pay attention
about this , Make the hard socket bigger than stump and use more socks or
thickness of soft liner and another way , can put the distal padding on distal end of
socket for prevent pressure and relief pain.
Appropriate materials
Materials and components should be
•Durable
•Simplify lengthening
•Switch out easily
•Very safety for children and parents

14. Advance technique
CAD/CAM technologyIcecast® Modular socket
system (MSS)• Spectra 3D and scanner : use white light that safe
for patient and can capture every bump and
contours.
• Vorum Canfit BK Transtibial Design Software :
Anatomical correctly
• 3-Axis Carving Machine : Durable, low
maintenance and accurate
• Total Surface Bearing (TSB) socket design
• Reducing rectification time
