The document discusses upper limb prosthetics, including different levels of amputation, types of prostheses, components, socket designs, suspension systems, and terminal devices. It defines various amputation levels from transphalangeal to forequarter and describes prosthetic options for each level. The major components of upper limb prostheses are the socket, suspension, control system, and terminal device. Socket designs vary depending on the amputation level and suspension type. Suspension systems include harness, self-suspending socket, suction, and semi-suction options. Terminal devices can be either passive cosmetic hands or active hooks and hands controlled by cable or battery.
3. Introduction:
Upper limb prosthesis is a device that replaces the missing part of the
upper limb and their function . Upper limb amputation are named by
the limb segments affected . An upper limb amputee requires a
complete and through evaluation at the level of involvement and also
associated functional and physical deficits .
Upper Limb Prosthesis
4. Objectives:
To determine the different levels of upper limb amputation
Learn about the types of prosthesis
To know about the components of an upper limb prosthesis
To know about appropriate prosthesis for different upper limb
amputations
To know about different socket design
To know about terminal devices
Upper Limb Prosthesis
5. Amputation
Surgical removal of affected body part or limb
Causes of amputation:
Trauma
Tumor
Infection
Vascular disease
Congenital
Upper Limb Prosthesis
7. Transphalangeal amputation:
Resection of the thumb or fingers at distal interphalangeal
(DIP),proximal interphalangeal (PIP), or metacarpophalangeal (MCP)
levels, or at any level in between
Transmetacarpal amputation:
Resection through the metacarpals
Transcarpal amputation:
Resection through the carpal

16. Socket design
(Name of the upper limb prosthesis depend on various factors)
Amputated body segment
Suspension types
According to the function
Upper Limb Prosthesis
22. Suspension :
The suspension system must hold the prosthesis securely to the
residual limb , as well as accommodate and distribute the forces
associated with the weight of the prosthesis .
Suspension system can be classified as follow:
1. Harnessed-based system .

24. Terminal Device:
The most distal component of upper limb prosthesis.
The major function of a hand that a terminal device tries to replicate is GRIP.
Griping types:
1.Cylindrical Grip
2. Tip Grip
3.Hook Grip
4. Palmar Grip
5.Spherical Grip
6.Lateral Grip
Upper Limb Prosthesis
25. Types of Terminal Device:
1. Passive terminal device : ( More cosmetic than functional)
Functional (Stablity,support)
Cosmetic (Cosmetic hands,gloves)
2. Active terminal devices: ( more functional than cosmetics)
Body powered (cable controlled,voluntary opening or closing)
Externally powered ( Electrically controlled,battary)
Can be both
Upper Limb Prosthesis
27. Conclusion
Upper limb amputations are not so common as lower limb
amputations
Upper limb prosthesis is prescribed after a holistical patient
assessment
Upper limb prosthetic components are chosen according to patient
expectations , either cosmetic or functonal.
As the prosthetic components are more costly, often patients don’t
want any prosthesis.
