amputation, account for 15% to 20% of major extremity amputations. More
than 90% of all upper-extremity amputations are a result of trauma, and
most of these occur in men between the ages of 20 and 40 years (1).
Limb-sparing surgery for primary bone and soft-tissue sarcoma of the
upper extremity is possible in the majority of patients, although
amputation may still be necessary for local control or palliation in 5%
to 10% of patients with malignant tumors (18).
Less common causes of upper-extremity amputation are peripheral
vascular disease, congenital malformations, neurologic disorders, and
consequences than the loss of a lower extremity. Upper-extremity
amputations are most common in young male trauma victims, in whom the
loss profoundly affects function and self-image. Despite improvements
in materials and design, long-term use of prosthetics by
upper-extremity amputees is only about 50%. Prosthetic use is reduced
in patients with higher levels of amputation, those with brachial
plexus injury, and when initiation of prosthetic limb rehabilitation is
amputation. Acutely severed, crushed, or mangled limbs may require
immediate amputation (19). Irreversible
brachial plexus injuries resulting in a flail, useless limb may come to
amputation following the acute injury period. Malignant bone or
soft-tissue tumors that contaminate or encase major nerves or vessels
may not be amenable to limb salvage. Tumors with extensive involvement
of the carpal tunnel or antecubital fossa may require amputation to
eradicate the tumor locally. Peripheral vascular disease that cannot be
corrected or reconstructed may require amputation, particularly in the
case of diabetes (10).
microsurgical technique, proximal arm replantation was accomplished
with limited success (14). Application of
microsurgical vascular and nerve repair has allowed successful
replantation of more distally severed arms and fingers. Preservation of
the arm or hand even with limited sensation or function is often
superior to an insensate prosthetic limb. Specific indications for
digit replantation have been developed as limitations in function of
the replanted part have become better appreciated (6,8,24). Absolute and relative contraindications for limb replantation are listed in Table 121.1.
Limb replantation at the transhumeral level is valuable in recovering
function of the elbow in most patients; however, more distal recovery
is less predictable. Replantation at this level may permit conversion
of an above-elbow amputation to a below-elbow amputation, thereby
improving rehabilitation potential and success of prosthetic use (22).
Short residual limbs following traumatic amputation in selected
individuals can be lengthened using bone distraction techniques (20).

following motor vehicle accidents or industrial or farming injuries.
The prognosis for recovery depends the location of the injury and its
extent. Nerve root avulsions are not reparable but may be reconstructed
with distal neurotization and muscle transfer, provided sufficient
donors are available. Extensive, multilevel nerve root avulsions may
result in a flail limb with little potential for recovery. Computed
tomography contrast myelography, axon response to intradermal
histamine, electromyography, somatosensory evoked potentials, and
magnetic resonance imaging may be useful means to identify nerve injury
location (11,15). Early
repair and intraoperative nerve conduction and stimulation have been
advocated to improve results of brachial plexus repair (9,15).
Absence of any clinical return of function after 1 year

above-elbow amputation and prosthetic rehabilitation. Within 3 to 6
months after a complete brachial plexus injury the patient becomes a
“one-handed” person, transferring most activities from the injured limb
to the normal limb. More effective rehabilitation and better prosthetic
compliance have been achieved with early above-elbow amputation and
prosthetic training, avoiding the development of single-hand function
Upper-extremity amputation for intractable pain following brachial
plexus injury is not successful in the majority of patients (3) (see Chapter 60).
upper extremity, excluding the hand, can be resected with wide margins
that spare the limb without adversely affecting survival (18).
Bone and soft-tissue reconstruction using tendon transfers, nerve and
vein grafts, and free microvascular tissue transfer allow both
functional and cosmetic reconstruction in the majority of cases. Tumors
that cannot be resected without the sacrifice of multiple major nerves,
or without excessive risk of local recurrence, usually require
amputation. The level of amputation must provide margins that preclude
local recurrence regardless of the functional impairment that results
from a more proximal level of amputation. See Chapter 126 and Chapter 128.
Perform upper-extremity amputations at
the most distal level compatible with uncomplicated wound healing.
Handle soft tissues atraumatically.
A tourniquet may be used; however, exsanguination is contraindicated in limbs being amputated for infection or tumor.
amputation at the most distal level provides the optimal stump for
prosthetic use. If the vascular status of the limb is compromised,
healing at the distal third of the forearm may be impaired owing to the
lack of well-vascularized muscle deep to the subcutaneous tissue. A
tourniquet may be used.
Fashion equal anterior and posterior skin flaps (Fig. 121.1), and ligate the radial and ulnar arteries.Figure 121.1. A below-elbow amputation, demonstrating equal dorsal and volar flaps.
Identify the major nerves (i.e., radial,
ulnar, median), sharply divide them as far proximally as possible, and
allow them to retract into the soft tissues.
Section the radius and ulna proximal to
the most proximal portion of the skin incision, and smooth the rough
edges with a rasp or rongeur.
Perform a myoplastic closure. If the
amputation level is proximal to the myotendinous junction of the flexor
and extensor tendons of the forearm, suture the palmar compartment
muscles over the end of the bone to the extensor compartment.
The most proximal level compatible with
below-elbow prosthetic fitting is the level of the biceps tendon
insertion on the radius. If circumstances require amputation at this
level, releasing the distal 2.5 cm of the biceps tendon provides a
longer stump for prosthetic fitting.
If the level of amputation is in the
distal one third of the forearm, bring the tendinous portion of the
flexor digitorum superficialis over the end of the bone and suture it
to the extensor compartment fascia.
Obtain hemostatis. If necessary, use a drain. Close the wound without tension, and apply a bulky compressive dressing.
a through-knee amputation in the lower extremity. The bulbous distal
humerus allows suspension of a prosthesis. The long lever arm allows
humeral rotation of the prosthesis, alleviating the need for the
mechanical turntable required in more proximal brachial amputations.
However, the soft tissue is thin at the elbow, and fitting of the
prosthesis must be exact.
A sterile tourniquet may be used. Fashion
equal anterior and posterior flaps, with the posterior flap extending
to a point 2.5 cm distal to the olecranon and the anterior flap
extending to the biceps insertion on the radius.
Ligate the brachial artery. Sharply
divide the radial, ulnar, and median nerves proximally. Allow them to
retract into soft tissue.
Disarticulate the elbow by dividing the
insertion of the biceps (i.e., radius) and the insertion of the
brachialis (i.e., ulna) anteriorly and by dividing the triceps tendon
at its olecranon insertion. Release the medial flexor and pronator mass
from the medial epicondyle, and divide the extensors from the lateral
Perform an anterior capsulotomy, and remove the forearm, leaving the articular surface of the distal humerus intact.
Bring the triceps tendon anteriorly and
suture it to the tendons of the biceps and brachialis muscles over the
trochlea of the humerus. Place a drain and close the wound without
tension. Apply a bulky compressive dressing.
includes an elbow lock mechanism for flexion and extension and an elbow
turntable for rotation, perform above-elbow amputations 3.8 cm proximal
to the joint. Amputation at the level of the surgical neck of the
humerus functions as a shoulder disarticulation; however, this level
has the cosmetic advantage of preserving normal shoulder contour.
For amputations through the midbrachium (Fig. 121.2), fashion equal anterior and posterior flaps.Figure 121.2. An above-elbow amputation using equal anterior and posterior flaps.
Identify and ligate the brachial artery.
Divide the anterior compartment muscles
approximately 1.3 cm distal to the intended level of bone transection.
Divide the triceps 5 cm distal to the intended level of bone
Section the humerus and smooth its rough edges with a rasp.
Perform a myoplastic closure, suturing
the anterior compartment muscles to the triceps. Close the wound
without tension over a drain. Apply a bulky compressive dressing.
For amputations through the surgical neck
of the humer us, make an incision anteriorly from the coracoid process
along the anterior border of the deltoid to the lateral insertion of
the deltoid on the humerus. Extend the incision posteriorly along the
posterior margin of the deltoid to the posterior axillary fold, and
connect the two incisions by an axillary incision.
Ligate the cephalic vein. Release the
deltoid muscle from its humeral insertion, and reflect it proximally.
Release the pectoralis major muscle from its humeral insertion, and
reflect it medially (Fig. 121.3).Figure 121.3. A proximal humeral amputation using the anterior approach.
Identify the neurovascular bundle, and
ligate the axillary artery. Sharply divide the musculocutaneous,
median, ulnar, and radial nerves, and allow them to retract proximally.
Divide the teres minor and latissimus
dorsi muscles close to their humeral insertion. At a point
approximately 2 cm distal to the intended bone section, divide the
coracobrachialis and biceps muscles, and reflect them distally.
Amputate the humerus at the surgical
neck. Suture the biceps and coracobrachialis muscles to the triceps
muscle over the stump of bone. Trim the deltoid laterally, and suture
it medially. Place appropriate drains, and close the skin without
disarticulation and the forequarter or scapulothoracic amputation, are
performed almost exclusively for tumors (2). A
functional prosthesis is not available for these amputations. The
Tikhor–Lindberg resection is performed for malignant tumors of the
shoulder girdle if there is no involvement or limited tumor involvement
of the neurovascular bundles. This resection resects the proximal
humerus, scapula, and clavicle but preserves the brachium and distal
arm (7). The anterior approach for forequarter
amputation has the advantage of allowing early control of the major
vessels under optimal visualization, whereas the posterior approach may
be advocated due to the progressively improved exposure obtained while
the weight of the arm acts to retract the major soft-tissue mass.
Begin an anterior incision at the
coracoid process, and proceed distally along the anterior margin of the
deltoid to its humeral insertion (5). Continue
posteriorly along the posterior margin of the deltoid, and connect the
anterior incision with a posterior incision across the axilla.
Identify the neurovascular bundle in the
interval between the coracobrachialis and the short head of the biceps,
and ligate and divide the axillary artery and vein. Sharply divide the
median, ulnar, and musculocutaneous nerves, and allow them to retract
into soft tissue.
Detach the deltoid from its humeral
insertion, and retract it along with its overlying skin proximally.
Release the coracobrachialis and short head of the biceps from their
origin from the coracoid, and release the humeral insertion of the
Externally rotate the arm, and divide the
anterior joint capsule and subscapularis muscle. Internally rotate the
arm, and divide the short external rotators and the teres major.
Divide the triceps and inferior capsule, and remove the arm.
Suture the muscle ends into the glenoid
to fill dead space. Bring the deltoid with its overlying skin
inferiorly, and suture it inferior to the glenoid to the margin of the
posterior axilla incision, completing the procedure.
Begin the incision lateral to the
clavicular insertion of the sternocleidomastoid muscle, and extend the
incision distally along the clavicle to the acromioclavicular joint
over the acromion to the spine of the scapula and posteriorly along the
vertebral border of the scapula (5,7).
Begin the lower incision at the middle
third of the clavicle. Proceed distally to the deltopectoral groove and
cross the axilla horizontally, and join the first incision posteriorly
at the spine of the scapula.
Release the pectoralis major from the
clavicle, and divide the clavicle lateral to the insertion of the
sternocleidomastoid. Excise the clavicle to the level of the
If necessary, ligate the external jugular
vein and release the pectoralis major and minor from their insertions,
exposing the neurovascular bundle.
Ligate and divide the subclavian artery and vein. Section the components of the brachial plexus, and allow them to retract.
Release the latissimus dorsi and axillary
fascia from the humerus, allowing the limb to fall posteriorly. Hold
the arm across the chest, and from superiorly to inferiorly divide the
remaining muscles that fix the shoulder to the scapula. Divide the
muscles that hold the scapula to the thorax, starting with the
trapezius and continuing through the omohyoid, levator scapulae,
rhomboid major and minor, and serratus anterior.
Remove the arm and scapula.
Suture the remaining muscle over the lateral chest wall, and close the skin flaps over suction drainage.
Resection replantation has been described by Windhager et al. (21) and is analogous to a Van Ness rotation plasty of the lower limb.
Resect the tumor-bearing portion of the

amputation may be treated with a rigid dressing and early prosthetic
fitting, as described by Burkhalter (4). Approximately 50% of upper-extremity adult amputees are rehabilitated with functional prosthetics (23).
Before initiating prosthetic fitting and training, consider the age,
extremity dominance, occupation, and psychosocial status of the patient
upper-extremity adult amputees should be fitted with at least one
functional prosthesis, usually one that is externally powered.
prostheses. The conventional body-powered prosthesis relies on proximal
shoulder girdle muscles to provide the force to power a terminal grasp
device through a system of harness and cables. Depending on the level
of amputation, the elbow and wrist “joints” must be positioned manually
by the contralateral normal limb. Myoelectric prostheses rely on
electrical potentials in active muscles in the stump to activate
electrodes in the prostheses, which switch electrical motors on and off
within the device. These prostheses are expensive, heavy, and require
initial prosthetic fitting determines the ultimate success of
rehabilitation. Malone demonstrated in a series of upper-extremity
amputees that prosthetic fitting within 1 month of amputation resulted
in a 93% success rate of prosthetic rehabilitation (26 of 28 patients) (12,13).
Among upper-extremity amputees fitted later than 1 month after
amputation, only 42% (9 of 19) achieved prosthetic rehabilitation.
Although advocates of rigid postoperative dressings
higher rates of early prosthetic use, their use should be limited to
those patients with normal sensation and well-vascularized soft tissues
that have not been injured by trauma.
