The document discusses various socket designs for different levels of upper limb amputations. It describes the key factors in socket design such as maximizing range of motion, stability, and force distribution. For transradial amputations, common socket designs include supracondyler brims, external suspension sleeves, and internal roll-on locking liners. The Munster and Northwestern sockets are described as examples of supracondyler designs. For transhumeral amputations, designs include open shoulder above elbow sockets and closed encasulated designs. The document also discusses some novel designs like the TRAC, CRS, and ACCI sockets that aim to improve suspension, reduce motion at bone-socket interface, and control rotation.

Prosthetic management of individuals with upper extremity
amputations presents all health professionals, including
prosthetists and therapists, with a set of unique challenges.
For those wearing an upper extremity prosthesis, the terminal
device (TD) of the prosthesis is not covered or obscured
by clothing in the same way that a lower extremity prosthesis
is “hidden” by pants, socks, and shoes. The person with
upper extremity amputation must cope with not only physical
appearance changes, but the loss of some of the most
complex movement patterns and functional activities of
the human body.
In addition, upper extremity limb loss deprives the patient
of an extensive and valuable system of tactile and proprioceptive
inputs that previously provided “feedback” to guide and
refine functional movement. Even the simplest tasks
related to grasp and release become challenging. The ability
to position the prosthetic limb segments in space, as well as
the ability to maintain advantageous postures needed to
manipulate objects, challenge the medical community to
continuously improve the functional and aesthetic outcomes
of prostheses for patients in this population.

This Presentation is about role of splinting in orthopedic condition and neurological condition. This presentation can be benefitted for Orthotist, Occupational therapist, phyiotherapist and Physical medicine and rehabilitation specialist.
An electric wheelchair offer mobility and the freedom to get around. A motorized wheelchair, powerchair, electric wheelchair or electric-powered wheelchair (EPW) is a wheelchair that is propelled by means of an electric motor rather than manual power. Motorized wheelchairs are useful for those unable to propel a manual wheelchair or who may need to use a wheelchair for distances or over terrain which would be fatiguing in a manual wheelchair. They may also be used not just by people with 'traditional' mobility impairments, but also by people with cardiovascular and fatigue-based conditions.The electric-powered wheelchair was invented by George Klein who worked for the National Research Council of Canada, to assist injured veterans after World War II.[1]
Over the past decade, technology and research have greatly expanded the functionality and aesthetics of prosthetic feet. Today, amputees have a wide array of feet from which to choose. Various models are designed for activities ranging from walking, dancing and running to cycling, golfing, swimming and even snow skiing.
Biomechanical principle of hand spliningPOLY GHOSH
Hand splinting are provided to people who need protection and support for painful, swollen or weak joints and their surrounding structures. Their designs make sure you position your wrist and hands correctly. There are two types of hand or wrist splint: splints used for resting joints of the wrist and hand.
Different types of electric terminal devices used for transradial and transhumeral, shoulder disarticutaion prosthesis used for external powered prosthesis.

2. SOCKET
One of the single most determining factors of whether a person will use a
prosthesis is prosthetic socket design.
socket designs and careful consideration of residual limb presentation sets
the stage for patient success-
1. maximizing range of motion.
2. providing stability throughout daily activities.
3. comfortably distributing the forces exerted on the residual limb during
movement and suspension.
Socket design for body powered prosthesis-
1. Harness suspended
2. Self suspended
4. Transphalangeal amputation ,Transmetacarpal amputation
and Transcarpal amputation (partial hand amputations)
No prosthetics intervention
Passive prosthesis
A body powered prosthesis
An externally powered prosthesis
Multiple tasking specific prosthesis
passive prosthesis
6. Socket design for partial hand amputation
Socket designs for partial hand prostheses preserve function of wrist joint
and other proximal jt.
Trimlines and socket contours are generally dictated by the geometry of
the remaining portions of the hand and fingers.
Goals:-
1. Protection of the residual limb.
2. bimanual stability
3. provide acceptable cosmesis and durability
7. TRANSRADIAL AND WRIST DISARTICULATION
SOCKET DESIGN
Socket designs fall into four categories:-
1. Supracondyler brims
2. External suspension sleeves
3. Suprastyloid suspensions
4. Internall roll-on locking liners
9. MUNSTER SOCKET
Self suspended
Short Transradial amputation.
The forearm was set in a position of initial flexion
(average 35 deg.).
The anterior trim line extended to the level of the antecubital
fold, a channel for the biceps tendon.
The posterior aspect of the socket enclosed the olecranon.
The trim line was just above the level of the epicondyles.
11. ADVANTAGES & DISADVANTAGES
Adv:-
1. Comfort and security.
2. Lifting and holding forces generally superior.
3. "Axial load"—resisting vertical downward force with the elbow extended.
Disadv:-
1. Active pronation & supination is eliminated.
2. Difficulty in donning and doffing as stump length increases.
3. Decrease in flexion range required modification in case of bi-lateral
socket.
12. NORTHWESTERN SUPRACONDYLER SOCKET
Accommodate all lengths of transradial amputations.
Provide an improved range of motion at the elbow.
Narrow M-L
Anterior trimline is below antecubital area,
The anterior trimline, superior to the humeral condyles, should be at least
3/8 inch smaller than the measured M-L dimension at
the humeral condyles.
Posterior trimlines be well rounded to accept
The contour of the upper arm, proximal to the
Humeral condyles. 1/2inch over the olecrenon process
13.
14. MODIFIED SUPRACONDYLER BRIM
Mainly for myoelectric Transradial prosthesis.
For long transradial amputations.
Has a olecrenon cut-out.
Also called three-quarter type below-elbow socket.
Cut-out length should not exceed 50% of the axial
stump length.
15. Adv:-
Ventilation greatly improved,
The skin of the stump remains dry making for a cooler socket in the
summer and a warmer stump in the winter.
Skin problems caused by maceration are eliminated
Comfort and wearing tolerance are greatly improved.
Suspension improved
Anatomical elbow is free to move.
Increased elbow flexion range.
Reduced bulkness at olecrenon areas.
Cosmetically pleasing.
16. FLOATING BRIM SUSPENSION
For long Transradial amputations and wrist disarticulation.
Provides some natural rotation at the wrist and allows for maximum
elbow freedom and movement
18. SUPRASTYLOID SUSPENSIONS
For wrist disarticulaion with prominent styloid process
1. Silicone bladder suspension- Allow volume adjustibility of stump.
2. Window/door suspension
19. INTERNALL ROLL-ON LOCKING LINERS
1. Shuttle lock system- For short and midlength transradial amputation
2. Lanyard locking system- long transradial amputation and wrist
disarticulation
Terminate distal to epicondyles
20. TRAC SOCKET
In 2003, Miguelez et al. Described this socket.
Incorporates design elements from both the muenster and northwestern
interfaces with more aggressive contouring of the anatomy to maximize load
tolerant areas of the residual limb.
Compression anterior and slightly inferior to the epicondyles, specifically
about the radial head on the lateral aspect.
On anterior/posterior plane, suspension is achieved by
compression into the cubital fold and supra-olecranon region.
The TRAC retains the high olecranon encapsulating posterior
trim line
The anterior trim line extending to the cubital fold with a
channel that allows relief for the biceps tendon.
Relies on hydrostatic pressure.
21. The TRAC addresses the deficits of previous designs by contouring five
key areas:
1) the antecubital region,
2) the olecranon region,
3) the epicondylar region,
4) the distal radial region, and
5) the wrist extensor and flexor musculature
The position and degree of displacement of the skeletal substructure while
wearing the TRAC interface are less affected during loading
22. TRIMLINE
Anterior:- follows the cubital fold.
Medial and lateral:-should parallel the medial border of the ulna and the
lateral border of the radius.
Posterior:-approximately 12 to 18 mm proximal to the superior aspect of
the olecranon, with a width similar to the width of the olecranon
23.
24.
25. CRS SOCKET
Compression/release stabilized socket
Longitudinal depressions added in the socket walls with
open release areas between the depressions that receive the
displaced tissue .
Reduce motion of the underlying bony structures with
respect to both the socket and the rest of the prosthesis.
The depressions and releases during cast-taking but only
by radically changing the way casts are taken.
Requires selective pressure during cast-taking.
26. ELBOW DISARTICULATION & TRANSHUMERAL
SOCKET
Socket design will vary with the length of the residual limb and
suspension method.
Different design:- Elbow disarticulation
1. Windowed socket
2. Screw-in socket
3. Flexible open frame
4. Fenestrated
31. ACCI SOCKET
Reduction in the lateral trim line of the socket
An aggressive modification into the deltopectoral groove anteriorly
a flattened socket just inferior to the spine of scapula,
A firmly compressed anterior-posterior (AP) dimension for
rotational control along the humeral axis .
A compressed medial-lateral (ML) dimension at the level of
the axilla
32. Humeral AP clasp design
Wedge shaped cross-section in the midsection of the socket.
Humeral shaft lies in the angle of the wedge.
Flattening lateral aspect of the anterior and posterior
socket walls creates the sides of the wedge.
33. CRS SOCKET
The antirotation wings are based on original
design of ACCI socket.
But this wings are smaller for added stability.
34. Shoulder Disarticulation Socket Design
Infraclavicular socket:-
Does not enclose shoulder to support
The weight of the prosthesis
Relies on deltopectoral muscle group aneteriorly
And scapular region posteriorly.
Less noticeable under the clothing.
Acrmioclavicular complex free to move within
the socket.
36. X-Frame socket
Uses very rigid material.
Full contact socket for amputations at the shoulder disarticulation,
interscapulothorasic level and amputation at the level of humeral
neck
Covers far less surface area, all superflous material has been
removed including the rigid portion of a traditional socket. Which
usually covers the superior aspects of the trapezius.
Resembles an “x” with its four corner roated inwardly to
compress the anteroposterior aspects of thorax superiorly and
inferiorly.
It uses outtrigger principles
Superior compression improves suspension via a wedge effect on
anterior and posterior part
37. Scapulospinal suspension is provided through posterior
superior strut which rest on the soft tissue near the
medial aspects of the scapular spine
Anterosuperior part provides pressure over the
deltopectoral region
An anteroinferior extension that dissipates both shear
and compressive force under load
A pliable saddle over the trapezius that act as a
suspension strap and an elastic memebrane which
maintained electrode contact even when wearer moves
the prosthesis through a wide range.
38. It permits the user to bend forward and to
move the shoulder while maintaining good
contact with electrodes.
It stabilizes the prosthesis against rotation
at its superior and inferior borders
Adv:
Greater stabiliity, heat dissipation, comfort
and kinesthesia
Better appearances
39. Perimeter frame-type socket
Made out of aluminium.
Cut-out at anterior,posterior and acromioclavicuar
regions.
did not use anatomic contouring
