Rehabilitation

Is the sum of activities required to ensure patients the best possible physical conditions so that they may by their own efforts regain as normal as possible a place in the community and lead an active, productive life.

Clinical team approach to Rehabilitation

The rehabilitation team concept gained popularity after World War II with the need to care for a large number of injured soldier, particularly those with amputations.

Because contemporary medical care is often fragmented with insufficient communication among clinicians, it is especially worthwhile to describe a model of excellent care in which all parties work co-operatively.

Amputation Amputation is the removal of a body extremity by trauma,

prolonged constriction, or surgery. As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene. In some cases, it is carried out on individuals as a preventative surgery for such problems.

Ideal Stump

21/11/2014

17

Surgical Technique The best type of surgical technique for an upper limb–

deficient individual is a myodesis approach, in which the surgeon sutures the residual muscles to the bone rather than to one another. This technique creates a much more stable platform for all forms of prosthetic management. Muscles can contract independently without soliciting undesired movement in nearby muscles. This particular surgical technique also creates clean, independent muscle delineation in the myoelectric user.

21/11/2014

18

Ideal Stump for Upper Limb Prosthetics

Some kind of prosthesis can be made for any kind of stump but for perfect prosthetic fitting a perfect stump is necessary. The characteristics of an ideal stump are: › Length › Suture line or scar› Range of motion › Musculature around the stump› Skin over stump› Tip of bone› Nerve Endings

21/11/2014

19

Length

Limb length plays an important role in what components can and cannot be fitted to the patient. Crucial decisions are made during surgery that can affect an amputee’s prosthetic livelihood.

21/11/2014

20

Shoulder Disarticulation

Disarticulations at the shoulder level severely hinder prosthetic function because virtually all shoulder motion is lost. In fact, the prosthesis is used primarily as a holding device when the patient is performing activities with both hands. Sparing the humeral head is preferable whenever possible to obtain the best appearance and prosthetic fit.

If humeral head is to b excised, after excising the humeral head, the cut ends of all muscles are reflected and secured into the glenoid cavity in an effort to fill the resulting hollow. Finally, partial excision of the acromion may be necessary to smooth the contour of the shoulder.

21/11/2014

21

Trans-humeral Amputation

Ideal humeral stump remains 20 cm (8 inches), not because circulatory defects sometimes arise in longer stumps, but rather because such a length provides all the leverage needed and enables the best type of limb to be provided, with the best functional results.

To allow enough clearance for the different types of conventional and electrical elbows, the postoperative residual limb, including distal soft tissue, should be at least 14 cm (5.5 inch) proximal to the most distal aspect of the olecranon.

The retention of the head of the humerus is always advisable when it is practicable, even though there will be no functional stump.

21/11/2014

22

Trans-humeral Cont.

Humeral stumps longer than the ideal may prevent the fitting of the type of arm that provides the best functional results, because there is not enough space for the fitting of the automatic elbow mechanism.

21/11/2014

23

Disarticulation at the Elbow

Disarticulations at the elbow are still in disfavor: the extra leverage is of no advantage. and the prosthesis that can be fitted is not comparable in efficiency with that available for the Trans Humeral Amputation

Although suspension is optimal, and humeral rotation can be captured, this level is least desirable because of cosmetic issues and limitation of applicable prosthetic elbows.

21/11/2014

24

Trans-radial Amputation

Ideal length continues to be 7 INCHES(17.8 cm). Owing to improved methods of fitting and suspension much shorter below-elbow stumps can now be fitted than was once found possible, and therefore the elbow joint should not be sacrificed without much consideration. Stumps longer than the ideal tend to develop circulatory defects, and the extra length is of no advantage.

21/11/2014

25

Transcarpal styloid level

The transcarpal styloid level allows for preservation of full supination, pronation, and wrist flexion and extension, provided that no traumatic event limits motion. Surgeons can make an anatomic decision about the styloids to enhance pronation and supination.

21/11/2014

26

Suture line or Scar

For all arm stumps amputation by equal anterior and posterior flaps, giving a terminal transverse scar, provides the best results.

21/11/2014

27

Range of motion (ROM)

The range of motion of the proximal joints to the stump should be full and free of pain for optimal use of the prosthesis.

21/11/2014

28

Musculature around the stump

In upper limb amputations as myodesis technique is used, muscles should be well attached to bone ends.

This technique creates a much more stable platform for all forms of prosthetic management.

Muscles can contract independently without soliciting undesired movement in nearby muscles. This particular surgical technique also creates clean, independent muscle delineation in the myoelectric user.

21/11/2014

29

Skin over the stump

Healthy sensate skin is essential to withstand the extra load associated with prosthetic fitting. It can also give a positional feedback of the prosthesis.

21/11/2014

30

Tip of the bone

It should be smooth particularly the tip should be bevelled and smoothened with a rasp or a file.

21/11/2014

31

Nerve Ending

When a nerve is severed during amputation, it will form an ending of nerve fibers called a neuroma. We want to position the nerve ending in well-cushioned soft tissue that’s away from the incision, any scar tissue, areas of pressure and throbbing vessels. There, the nerve ending will not be irritated by traction, pressure from the prosthetic socket or any other unwanted sources of contact.

Knowledge of prosthetic designs and areas of contact or pressure will aid the surgeon in nerve placement. The surgeon’s goal is to retain as much of the useful remaining nerve function in the residual limb as possible, while also carefully managing the nerves to minimize nerve scarring and painful neuromas.

33

Postoperative Management

Management during the postoperative period is crucial to the patient‘s future functional abilities.

Physical & psychological issues not addressed during this critical time can hinder a person’s recovery and quality of life.

21/11/2014

34

Postoperative care All postoperative protocols have similar goals to:

› Heal the surgical wound.› Minimize pain.› Protect the amputated limb from trauma.› Preserve and improve the range of motion and strength

of the entire body.› Reduce swelling and begin shaping the amputated limb.› Facilitate psychological adjustment to limb loss.

21/11/2014

35

Residual Limb Shrinkage and Shaping

Shrinking and shaping of the residual limb is usually accomplished by compression from an elastic bandage, intermittent positive-pressure compression, or a tubular elastic bandage. If an elastic bandage is used, it is important that the proper technique be taught to the patient, family, and nursing staff. A figure-of-8 wrap is one that applies more pressure distally than proximally; elastic bandaging should never be done in a circumferential manner.

The wrapping process begins with the end of the bandage placed diagonally at the distal end of the residual limb. The wrap should encircle the limb from behind and wrap diagonally upward to cross over the end of the bandage. This figure-of-8 process should continue, with each pattern overlapping the previous one by approximately two thirds the width of the bandage. The bandage is then secured with tape or special clasps.

3621/11/2014

37

Residual Limb Shrinkage and Shaping

No elastic bandage should be used for more than 48 hours without being washed with mild soap and lukewarm water and thoroughly rinsed with clean water. Bandages should not be twisted, but laid flat to dry. Washers and dryers decrease their longevity and ruin their elasticity.

The wrap should be reapplied every few hours or more frequently if it slips or bunches. The elastic bandage should be worn all day and all night except when bathing. A preparatory prosthesis might also be applied early in the shaping process; however, a compression bandage is generally preferred because it affords better monitoring of skin healing and points of pressure.

Prosthesis Prosthesis is a device designed to replace, as much as

possible, the function or appearance of a missing limb or body part. An orthosis, in contrast, is a device designed to support, supplement, or augment the function of an existing limb or body part.

21/11/2014

42

Characteristics Of a Successful Prosthesis

Ideally, a prosthesis must be comfortable to wear, easy to put on and remove, lightweight, durable, and cosmetically pleasing. Furthermore, a prosthesis must function well mechanically and require only reasonable maintenance. Finally, prosthetic use largely depends on the motivation of the individual, as none of the above characteristics matter if the patient will not wear the prosthesis

Considerations When choosing a Prosthesis

Amputation level Contour of the residual limb Expected function of the prosthesis Cognitive function of the patient Vocation of the patient (eg, desk job vs manual

labor) Avocational interests of the patient (ie, hobbies) Cosmetic importance of the prosthesis Financial resources of the patient

Myoelectric Limb

Powered artificial hand or limb that detects electrical changes in the muscles of the stump and converts these into movements.

21/11/2014

56

Myoelectric Limb

Myoelectric Limb picks up the electrical action potential in the residual muscles in the amputated limb.  Upon receiving the action potentials, the prosthesis amplifies the signal using a rechargeable 6-volt battery and uses the electric signals to power the motors operating the respective part of the arm.  Unlike the two aforementioned types of prosthetics, myoelectric prosthesis allows for a much higher degree of freedom and does not require the patient to performed frequent strenuous muscle contractions.

I-Limb

Touch Bionics' i-limb prosthetic hand has advanced quite a bit in recent years, adding features like Bluetooth connectivity and upgraded fingers. Now the company has made available its latest revision, the i-limb ultra revolution, which offers powered thumb rotation for some added dexterity, as well as a new "biosim" app (iOS-only for now) that gives the wearer quick access to 24 different grip patterns in addition to diagnostic and training modes. Of course, the hand isn't only controlled using a phone; as with previous models, it relies on muscle signals to shift into different pre-set patterns, which let the wearer perform a wide variety of actions. You can get a glimpse of some of those capabilities in the video after the break.
