Q

Describe the general surgical technique for amputation

Q

Q

What is the physiological impact following amputation?

A

Q

Why can contractures form following amputation?

A
  • Failure to initiate full ROM early in post-op phase and poor positioning significantly increased risk of contracture
  • Joint immediately proximal to amputation is most susceptible

Q

What is phantom limb?

A
  • Painless sensation where the patient feels that the limb is present
  • Commonly immediately after amputation & will usually subside with desensitization & prosthetic use, however it may continue for extended periods of time for some patients

25
What is phantom pain?
- Patients perception of some form of painful stimuli as it related to the residual limb - Continuous or intermittent, local or general, short term or permanent
26
What are some treatment options for phantom pain?
- TENS - Ultrasounds - Icing - Mirror therapy - relaxation techniques - Desensitization techniques - Prosthetic use
27
Why is hypersensitivity an issue following amputation?
- Can impede or even prevent the appropriate fit & functional use of prosthesis
28
What are treatment options to combat hypersensitivity after an amputation?
- Specific de-sensitization techniques & early fitting of a temporary prosthesis are key components - Weight bearing, massage, tapping, & residual limb wrappings are all commonly utilized
29
What are some risk factors for amputation?
- Male - Smoking - Poor glycemic control - Depression
30
What are some risk factors for re-amputation, re-ulceration, mortality?
- Previous amputation - Level of amputation - Comorbidites
31
Name some reasons for amputations
- Diabetes - PVD - Tumors - Infections - Burn injuries - Trauma
32
What is a PVD?
Any abnormal condition affecting blood vessels peripheral to the heart
33
What can a PVD be caused by and lead to?
- Caused by: embolism, thrombosis, trauma, vasospasm, inflammation, arteriosclerosis - Leads to: Deficits in arterial, venous, lymphatic systems
34
How do electrical burns occur?
Direct contact with high-voltage electrical current
35
How can thermal burns occur?
- Extreme heat - Frostbite
36
Name some examples of trauma that can cause amputations
- MVA - non-union fractures - Military conflicts - Work accidents
37
Why has the number of wartime amputations decreased?
- Recent wars have lowest fatality rates - Improvement in body armor - Tourniquet use - Surgeons deployed
38
What is limb deficiencies?
- Congenital amputation - Partial or total absence of a structure along the long axis of a segment
39
How can limb deficiencies be treated?
- Possible surgical intervention (Ilizarov-Limb lengthening procedure) - amputation
40
What are the goals of PT with limb deficiencies?
- Maintain ROM above & below fixation - Strengthen the limb - Encourage weight bearing - Increase endurance - Restore function
41
What are the general principles of amputation in children?
- Preserve proximal joints (hip, knee) - Preserve length (growth plates) - Amputate through the joint if vital bone can not be salvaged - Proximal osteotomies or external fixation techniques may be needed to accommodate growth
42
What is the level of amputation dependent on?
- Vascular status of limb - Neuropathy - Infection - Necrosis - Malignancy - Bone & joint condition - Age - Function & rehab potential
43
What is a tarsometatarsal (lisfranc) amputation?
- Removal of metatarsals - Preserved the dorsiflexors & plantar flexors
44
What is a transverse tarsal (chopart) amputation?
- Amputation through the talonavicular & calcaneocuboid joints - Preserves the plantar flexors but sacrifices the dorsiflexors often resulting in equines contracture

What is a transhumeral amputation?
Removal of the upper extremity proximal to the elbow joint

Removal of the upper extremity through the shoulder
59
What is a forequarter amputation?
Remove of the upper extremity including the shoulder girdle
