Amputation: Presentation Goals
• Etiology
• Techniques
• Prosthetics and Rehabilitation
Amputation: Etiology
• Trauma
• Burns
• Peripheral Vascular Disease
• Malignant Tumors
• Neurologic Conditions
• Infections
• Congenital Deformities
Etiology: Trauma
• 90% of Upper Extremity Amputation• Male:Female = 4:1• Most Amputations at level of Digit• Major Limb Amputations less common• Revascularization sometimes possible for
incomplete amputation• Replantation sometimes possible for
complete amputation
Etiology: Trauma
Etiology: Tumor
Etiology: Infection
Etiology: Gangrene/Necrotizing Fasciitis
Radiograph: Subcutaneous air throughout arm
Etiology:Failed Forearm Vascular Repair after trauma
Etiology: Vascular Disease
Ischemia after AV Fistula Procedure
Etiology: Crush
Etiology: Congenital
polydactyly
Etiology: Infarction associated with IV Drug Abuse
Etiology: Scleroderma
Amputation: Trauma and Replantation
• Candidates for Replantation after Trauma– 1. Thumb– 2. Multiple Digits– 3. Partial Hand– 4. Wrist or Forearm– 5. Above Elbow– 6. Isolated Digit Distal to FDS insertion– 7. Almost any part in child
Amputation: Trauma and Replantation
• Candidates for Replantation after Trauma– Clean cut– Limited crush– Limited contamination– Acceptable ischemia time
• 6 hours with muscle• 24 hours with digit
Replantation: Multiple Digits
Surgical Technique: Digit Replantation
• 1. Identify Vessels and Nerves• 2. Debride• 3. Shorten and fix bone• 4. Repair Extensor Tendon• 5. Repair Flexor Tendon• 6. Repair Arteries• 7. Repair Nerves• 8. Repair Veins• 9. Skin Closure (skin graft if necessary)
Amputation: Replantation
• Poor Candidates for Replantation– 1. Severely crushed or mangled parts– 2. Multiple levels– 3. Other serious injuries or diseases– 4. Atherosclerotic vessels– 5. Mentally unstable – 6. > 6 hours ischemic time– 7. Severe contamination
Amputation: Replantation
Mangled and Crushed – Poor Candidate
Ectopic “banking” of amputated parts
Ectopic “banking” of amputated parts
Indicated for extensive injuries with adequate amputated part in setting of contaminated or absent support structures.
Recipient sites described- anterior thorax, contralateral arm/leg, groin. High complication rate.
Largest and original series described by Marko Godina 1986.

hand
Surgical Technique: Major Limb Replantation
• Myonecrosis is greater concern than in digit replant• Immediate shunting to obtain arterial inflow may be
necessary• High Potassium levels (>6.5 mmol/l ) in venous
outflow from amputated part negative prognostic factor
• Sequence of repair similar to digit– Identify structures, Debride, Rapid bone stabilization,
Vascular repair (artery then veins), Tendons and Nerves
Upper vs Lower Limb
• Upper extremity nonweightbearing– Less durable skin acceptable– Decreased sensation better tolerated– Joint deformity better tolerated– Late amputations rare– Transplants now being performed

Amputation: Major Limb Replantation Outcomes
• >2/3 survival rate
• Can be a life threatening undertaking
• Multiple Surgeries often required– Late Nerve, Bone, Tendon Surgeries
• Function of major upper extremity replantations even though poor can be superior to prosthetic function
Outcomes: Major Limb Replantation
• Comparison of functional results of replantation versus prosthesis in a patient with bilateral arm amputation
Peacock, Tsai, CORR, 1987• Major amputation of the UE: Functional Results after
replantation/revascularization in 47 casesDaoutix et al, Acta Orthop Scand, 1995
• Major Replantation versus revision amputation and prosthetic fitting in the upper extremity: a late functional outcome study
Graham et al, J Hand Surg, 1998
Amputation: Technique
• Preservation of functional residual limb length
balanced with
• Soft tissue reconstruction to provide a well-healed, nontender, physiologic residual limb
Technique: Determination of Level
• Zone of Injury (trauma)
• Adequate margins (tumor)
• Adequate circulation (vascular disease)
• Soft tissue envelope
• Bone and joint condition
• Control of infection
• Nutritional status

Forequarter Amputation

Emergent Open Shoulder Disarticulation

High TranshumeralNerves Avulsed
from High in Plexus
Failed Vascular Repair
Transradial
Levels of Amputation
• Wrist Disarticulation vs. Transradial– Disarticulation offers potential of better active
pronation and suppination of forearm– Transradial often difficult to transmit rotation through
prosthesis– Disarticulation poor aesthetically– Disarticulation more difficult to fit prosthetic– Transradial needs to be done 2 cm or more proximal to
joint to allow prosthetic fitting– Transradial usually favored
Levels of Amputation
• Transhumeral vs. Elbow Disarticulation– Adults: Elbow disarticulation allows enhanced
suspension and rotation control of prosthesis however retention of full length precludes use of prosthetic elbow. Long transhumeral favored
– Pediatrics: Transhumeral amputation results in high incidence of bony overgrowth. Elbow disarticulation is level of choice. Humeral growth slowed after trauma.
Levels of Amputation
• Preservation of Elbow function is a priority– Consider replantation/salvage of parts to
maintain elbow function– 4-5 cm of proximal ulna necessary for elbow
function– For very proximal amputations, it may be
necessary to attach bicep tendon to ulna
Techniques
• Debridement of all Nonviable tissue and foreign material
• Several debridements may be required• Primary wound closure often contraindicated• High voltage, electrical burn injuries require
careful evaluation because necrosis of deep muscle may be present while superficial muscles can remain viable
Techniques
• Nerve: Prevent neuroma formation– Draw nerve distally, section it, allow it to
retract proximally
• Skin: – Opportunistic flaps– Rotation flaps– Tension free– Skin grafts
Techniques
• Bone:– Choose appropriate level– Smooth edges of bone– Narrow metaphyseal flare for some
disarticulations
Postoperative Dressing:– Soft– Rigid
Techniques
• Goals of Postoperative Management– Prompt, uncomplicated wound healing– Control of edema– Control of Postoperative pain– Prevention of joint contractures– Rapid rehabilitation

Rehabilitation and Prosthetics
Rehabilitation
• 1. Residual Limb Shrinkage and Shaping
• 2. Limb Desensitization
• 3. Maintain joint range of motion
• 4. Strengthen residual limb
• 5. Maximize Self reliance
• 6. Patient education: Future goals and prosthetic options
Psychological Adaptation
• Amputation represents loss of function, sensation and body image
• Psychological response is determined by many variables– Psychosocial/Age– Personality– Coping Strategies– Economic/Vocational– Health– Reason for amputation
Psychological Adaptation
• Up to 2/3 of amputees will manifest postoperative psychiatric symptoms– Depression– Anxiety– Crying spells– Insomnia– Loss of appetite– Suicidal ideation
Psychological Adaptation: Stages
• 1. Preoperative– Tumor, Vascular Disease, Chronic Infection– Support Groups
• 2. Immediate Postoperative– Hours to days– Safety, Pain, Disfigurement
• 3. In-Hospital Rehabilitation• 4. At-Home Rehabilitation
In-Hospital Rehabilitation
• Initial: concerns about safety, pain, disfigurement• Later: emphasis shifts to social reintegration and
vocational adjustments
• Grief Response:– 1. “numbness” or denial– 2. yearning for what is lost– 3. Disorganization: all hope is lost for recovery of lost
part– 4. Reorganization
Management of Amputee
• Preparation
• Good Surgical Technique
• Rehabilitation
• Early Prosthetic Fitting
• Team Approach
• Vocational and Activity Rehabilitation
Prosthetics• Passive
– Cosmetic
• Body Powered– Harnesses and cables
• Myoelectric– Surface EMG– Activation delay
• Neuroprosthetics– Investigational at this time
Rehabilitation
Suggested timeline for transradial amputation
• 1-14 days: immediate postop prosthesis
• 2-4 weeks: training body powered prosthesis
• 6-12 weeks: definitive body powered prosthesis
• 6-12 weeks: training electronic prosthesis
• 4-6 months: definitive electronic prosthesis
