1
Q

amputation

A
  • The removal or loss of a limb segment or an entire limb, due to medical illness, trauma/incident, and or surgical measures in order to prevent the spread of disease and/or control pain.

Q

causes- congenital

A
  • Results from failure of the fetus properly developing within the first 3 months of maturation.
  • Congenital limb losses account for about 60% of all amputations

Q

causes- acquired

A

-Can result from an incident site, animal attack, trauma, diabetes, tumor, any illness leading to surgical measurements.
- Acquired usually results in medical procedures which help control or eliminate the process of disease or the
already affected limb.

Q

incidence

A
  • About 185,000 amputations occur annually
  • Below the knee are most common
  • Leading causes of amputations are;
  • Due to cancers or vascular diseases
  • Example: Malignant tumor
  • Second leading cause is trauma
  • Such as accidents which will lead to a part of a limb or whole limb being severed.

Q

classifications

A

Amputations can be classified according to level and site of limb absence and/or the functional point of view.
- They can be identified as above the knee(AK), below the knee(BK), above the elbow(AE), below the
elbow(BE).

Q

diagnosis

A
  • Chronic diseases such as peripheral artery disease (PAD) and foot ulceration
    result in limb amputation
  • Critical limb ischemia (CLI) results in 25% of patients requiring an amputation
    ○ Diagnosis includes: vascular examination, ankle-brachial index (ABI), and imaging modalities
  • Diabetes mellitus is related to 40-60% of lower extremity amputations
    ○ 85% of these amputations are caused by a foot ulcer, resulting in an infection and/or destruction
    of deep tissues
  • Amniotic band syndrome (ABS): Rare condition that can cause limb amputation
    of a baby due to restricted blood flow
    ○ Diagnosis: ultrasound

Q

treatment/preventative measures

A

Preventative Measures:
- Foot ulcers can be prevented by having regular foot inspections, having access to foot care and wearing proper footwear
Treatment:
- Treating a diabetic foot is a multidisciplinary approach which includes strategies for treatment of:
○ Peripheral ischemia, oedema, pain, infection, metabolic disturbances and malnutrition; non weight
bearing, topical treatment, foot surgery, aggressive management of intercurrent disease
- CLI treatment should be individualized to the patient
Recovery:
- After amputation it is important to avoid stump complication such as bleeding, infection, and contracture
- Appropriate care includes:
○ Proper elevation, regular repositioning, routine exercises to strengthen the stump and leg muscles

Q

severity scores

A
  • Injury severity scores include:
    ○ MESS (Mangled Extremity Severity Score)
    ○ PSI (Predictive Salvage Index)
    ○ LSI (Limb Salvage Index)
    ○ NISSA (Nerve injury, Ischemia, Soft tissue injury, Skeletal injury, Shock,
    patient age)
    ○ HFS (Hannover Fracture Scale)

Q

Critical Limb Ischemia

A

○ considered a severe form of PAD so it would
be classified on the severe end of the
Fontaine classification or the Rutherford
classification
○ Fontaine: defines the distances at which pain
occurs
○ Rutherford: describes 7 stages of PAD

Q

complications

A
  1. Phantom Limb Pain
    - Chronic neuropathic pain that develops in 45–85% of patients
    - Can affect an individuals capacity for self-care
    - The pain can lead to depression and feeling of hopelessness
  2. Infections
    - consequences of infection may include the need for wound revision or re-amputation at a
    higher level
    - Can also potentially increase the rate of secondary postoperative complications, which
    may include acute myocardial infarction, pneumonia and even death, or late complications
    such as poor long-term mobility and independence
17
Q

prosthetics

A

● Can be fit for almost any level of amputation
-knee disarticulation
-hip disarticulation
-elbow disarticulation,
-shoulder
● Can help restore locomotion and functional abilities
-potential to restore function and increase quality of life
● Require special training to use

18
Q

types of prosthetics

A
  • Mechanical
  • Electrical
  • Recreational arms and legs
  • Myoelectric Arm
19
Q

signal training

A

which teaches the amputee how to control the muscles used to control the prosthetic arm

20
Q

control training

A

amputee learns to control the specific muscles

21
Q

functional training

A

amputee must learn to become accustomed to wearing

the artificial limb and see it as part of their body

22
Q

teaching considerations in classroom

A
  • People with amputation will typically require accommodation to move from one place to another
  • Create a physically accessible environment that is not mobility-limited.
  • Big doors, ramps
  • Be flexible with the schedule. Students may arrive late or have to leave before the class is over due to adapted transportation services.
  • May need to recap the information given at the beginning of the lesson
  • Location of where the student is seated
  • Consider emergency situations
23
Q

participation in PA

A

● People with amputation are generally inactive.
○ 68% of amputee population compared to 40% general population
● There is a decrease in the level or leisure activity following lower limb amputation.
● However, satisfaction with changed physical status remains high.
● Likelihood of participating in physical activity exercise and sport increased if they
participated prior to amputation.
● If they do return to physical activity they opt for less demanding activities where a
prosthesis is not required or not functionally dependent on a prosthesis to participate
- Example: fishing, swimming, etc.

24
Q

barriers for PA

A 
● Physical limitation
● Lack of confidence / embarrassment
● Body image
● attitude
● Services
● Climate/physical environment
● Income
● Stump pain
● Prosthesis
25
Q

teaching considerations in gym

A
  • In general, a physical education program for students with amputation can follow the same guidelines as for students without disabilities.
  • Adaptation depends on the location, extent of the amputation and type of activity.
    1. Physical Fitness
  • Students with BK or AK often have lower levels of aerobic functioning
  • Activities should be chosen that do not cause overuse injury or skin breakdown
  • Suggested aerobic activities include: swimming, rowing, using an arm propelled tricycle, etc.
    2. Motor Skills
  • Acquired BE, AE, BK, AK amputations can result in awkward or clumsy performance of motor
    skills.
  • Activities that foster the development of balance and proper body alignment should be encouraged;
    these include traversing an obstacle course, performing on a mini-trampoline, or walking
26
Q

possible accommodations

A
  1. Instruction
    - Print out instructions and presented in a way so the child knows that they are expected to do.
    - Students may have a peer partner to help
  2. Rules
    - Rules can be relaxed to allow the student to achieve the desire goal.
  3. Equipment
    - Bats or paddles have Velcro strapping to help the child grip it
    - Lowering basketball nets
    - Smaller balls
    - Scoops for catching
  4. Environment
    - Padding
    - Hand holds
    - Adaptive equipment
27
Q

  1. The War Amps
    - Provide financial assistance to amputees for their artificial limb.
    - Educate amputees with information on artificial limbs and all aspects of
