and restore function, prevention of adjacent joint contractures, early return of patient to work and recreation, 1.7 million individuals in the United States with an amputation, 80% of amputations are performed for vascular insufficiency, Amputations may be indicated in the following, most common reason for an upper extremity amputation, most common reason for a lower extremity amputation, perform amputations at lowest possible level to preserve function, Syme amputation is more efficient than midfoot amputation, inversely proportional to length of remaining limb, Ranking of metabolic demand (% represents amount of increase compared to baseline), varies based on patient habitus but is somewhere between transtibial and transfemoral, most proximal amputation level available in children to maintain walking speeds without increased energy expenditure compared to normal children, measurement of doppler pressure at level being tested compared to brachial systolic pressure, pressure-sensitive implanted medical device (automatic implantable cardiac defibrillator, pacemaker, dorsal column stimulator, insulin pump), Amputation versus limb salvage and replantation, mangled upper extremity has a far greater impact on overall function than does a lower extremity amputation, upper extremity prostheses have much more difficulty replicating native dexterity and sensory feedback provided by the native limb, results of nerve repair and reconstruction are more successful in upper extremity than lower extremity, superior functional outcomes can be expected in replanted limbs compared with upper extremity amputations, diminishing outcomes from replantation are expected the more proximal the level, especially about the elbow, wrist disarticulation or transcarpal versus transradial amputation, recommended in children for preservation of distal radial and ulnar physes, can be difficult to use with highly functional prosthesis compared to transradial, Although, this may be changing with advancing technology, easier to fit prosthesis (myoelectric prostheses), transhumeral versus elbow disarticulation, indicated in children to prevent bony overgrowth seen in transhumeral amputations, All named motor and sensory branches within operative field should be identified and preserved, can result in improved muscle mass and preserve the ability to create myoelectric signal for targeted reinnervation, myodesis, the process of attaching the muscle-tendon unit directly to bone is recommended, anchor wrist flexor/extensor tendons to carpus, middle third of forearm amputation maintains length and is ideal, residual 5cm of ulna is required for elbow motion, but at this level will have limited pronation/supination, ideal level is 4-5cm proximal to elbow joint, At least 5-7cm of residual length is needed for glenohumeral mechanics, retain humeral head to maintain shoulder contour, designed to improve control of myeolectric prostheses used for amputation, transfer amputated large peripheral nerves to reinnervated functionally expendable remaining muscles to create a new discrete muscle signal for the myoelectric prosthesis control, secondary benefit of alleviating symptomatic neuroma pain, however, ideal cut is 12 cm (10-15cm) above knee joint to allow for prosthetic fitting, 5-10 degrees of adduction is ideal for improved prosthesis function, creates dynamic muscle balance (otherwise have unopposed abductors), provides soft tissue envelope that enhances prosthetic fitting, amputation through the femur near level of adductor tubercle, synovium is excised to prevent postoperative effusion, patella is arthrodesed to the end of femur for improved end bearing, prepatellar soft tissue is maintained without iatrogenic injury, improved outcomes as compared to transfemoral amputation, ambulatory patients who cannot have a transtibial amputation, suture patellar tendon to cruciate ligaments in notch, use gastrocnemius muscles for padding at end of amputation, Consequence of poor soft tissue envelope from loss of gastrocnemius padding, 12-15 cm below knee joint is ideal (10-16cm of residual tibia bone), longer than this gets into the achilles tendon which has a suboptimal blood supply and ability for soft tissue cushioning, need approximately 8-12 cm from ground to fit most modern high-impact prostheses, preventable with well-designed incision lines, preserve blood supply to the posterior flap, designed to enhance prosthetic end-bearing, argument is that the bone bridge will enhance weight bearing through the fibula and increase total surface area for load transfer, increased reoperation rates have been reported, the original Ertl amputation required a corticoperiosteal flap bridge, the modified Ertl uses a fibular strut graft, requires longer operative and tourniquet times than standard BKA transtibial amputation, fibula is fixed in place with cortical screws, fiberwire suture with end buttons, or heavy nonabsorbable sutures, used successfully to treat forefoot gangrene in diabetics, medial and lateral malleoli are removed flush with distal tibia articular surface, the medial and lateral flares of the tibia and fibula are beveled to enhance heel pad adherence, removal of the forefoot and talus followed by calcaneotibial arthrodesis, calcaneus is osteotomized and rotated 50-90 degrees to keep posterior aspect of calcaneus distal, allows patient to mobilize independently without use of prosthetic, Chopart or Boyd amputation (hindfoot amputation), a partial foot amputation through the talonavicular and calcaneocuboid joints, avoid by lengthening of the Achilles tendon and, leads to apropulsive gait pattern because the amputation is unable to support modern dynamic elastic response prosthetic feet, unopposed pull of tibialis posterior and gastroc/soleus, prevent by maintaining insertion of peroneus brevis and performing achilles lengthening, a walking cast is generally used for 4 week to prevent late equinus contracture, Energy cost of walking similar to that of BKA, more appealing to patients who refuse transtibial amputations, almost all require achilles lengthening to prevent equinus, preserves insertion of plantar fascia, sesamoids, and flexor hallucis brevis, reduces amount of weight transfer to remaining toes, prevent with early aggressive mobilization and position changes, trauma-related amputation have an infection rate of around 34%, prevent with proper nerve handling at the time of procedure, a method of guiding neuronal regeneration to prevent or treat post-amputation neuroma pain and improve patient use of myoelectric prostheses, occurs in 53-100% of traumatic amputations, mirror therapy is a noninvasive treatment modality, most common complication with pediatric amputations, prevent by performing disarticulation or using epihphyseal cap to cover medullary canal, Outcomes are improved with the involvement of psychological counseling for coping mechanisms, Involves a close working relationship between rehab physicians, prosthetists, physical therapists, as well as psychiatrists and social workers, High rate of late amputation in patients with high-energy foot trauma, highest impact on decision-making process, 2nd highest impact on surgeon's decision making process, plantar sensation can recover by long-term follow-up, SIP (sickness impact profile) and return to work, mangled foot and ankle injuries requiring free tissue transfer have a worse SIP than BKA, most important factor to determine patient-reported outcome is the ability to return to work, About 50% of patients are able to return to work, study focused on military population in response to LEAP study, slightly better results in regard to patient-reported outcomes for the amputation group with a lower risk of PTSD, more severe limbs were going into salvage pathway, military population with better access to prostheses, higher rates of return to vigorous activity in the amputation group, Descending thoracic aorta graft, with or without bypass, Laparoscopy, surgical, ablation of 1 or more liver tumor(s); radiofrequency.
