[8], Amputation of the whole lower limb and ipsilateral hemi-pelvis[13] This type of amputation is most rare. Amputee Coalition 2008. Available from: I give my consent to Physiopedia to be in touch with me via email using the information I have provided in this form for the purpose of news, updates and marketing. It is performed to remove diseased tissue or relieve pain. In trauma[4] one or more of these blood vessels may be ruptured beyond repair due to the nature of the injuries sustained – e.g. Medical Dictionary, phocomelia. 2018 Aug 1;32(4):234-40. The boundary of dead or diseased tissue - if the infection or disease is not completely eradicated the patient may need to undergo further operations or treatment so it is important that the amputation is done at a level where this can be achieved. Surgery (Oxford). Burgess EM, Zettl JH. 54% of all upper limb amputations are as a result of trauma; in comparison, only 3% of lower limb amputations are as a result of trauma. Clegstories. In some countries, amputation of the hands, feet or other body parts is, or was used as a form of punishment for people who committed crimes. Surgery video for through knee amputation: This amputation is done through the femur, measurements are taken and flap lines marked out. It is a myoplasty of the antagonist muscles to help pad the end of the stump to perform Gottchaltk myodesis (adductor magnus trans-osseously fixed and covering the distal femoral end), Advantages and Disadvantages Original Editor - Lucy Coughlan as part of the World Physiotherapy Network for Amputee Rehabilitation Project, Amputation is the cutting off or the removal of limb/extremity or part thereof. Amputation has also been used as a tactic in war and acts of terrorism; it may also occur as a war injury.[1]. This in turn allows for a greater functional use of the stump and maintains soft tissue coverage of the remnant bone. Sign up to receive the latest Physiopedia news, The content on or accessible through Physiopedia is for informational purposes only. In order to minimise the risk of neuropathic pain (see complications) the nerves are dissected on tension so the end will retract back into the tissues where they can heal away from the stump end. Every care should be taken to assure that the amputation is done only when clinically indicated. Mobility and function - it is useful to consider the patients’ pre-morbid level of mobility and function. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). 1969 Jan 1;13(1):1-2. 1173185, Transtibial / Below Knee Amputation (BKA), Knee Disarticulation Amputation (KDA) / Through Knee Amputation, Transfemoral (TF)/ Above Knee Amputation (AKA), Other Types of Amputation in the Lower Limb. Upper limb amputations are seen more rarely than lower limb amputations. Amputation Definition Amputation is the intentional surgical removal of a limb or body part. A traditional hip disarticulation is done by separating the ball from the socket of the hip joint, while a modified version retains a small portion of the proximal (upper) femur to improve the contours of the hip disarticulation for sitting. In most cases Physiopedia articles are a secondary source and so should not be used as references. This is a complete list of all services requiring a Prior Approval for HIP members (jointly referred to as "pre-authorization") subject to their benefit plan's coverage for … As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene. Available from: Richard Major. Sharp and rough edges of the bone are filed down, skin and muscle flaps are then transposed over the stump. 1-2 cm shorter than the tibia on a perpendicular axis. With a transfemoral amputation, the distal attachments of the thigh muscles are lost, in order to preserve their function and length, a myodesis may be performed to anchor the adductor (and sometimes hamstring) muscles to bone. This video shows one example of how a transtibial amputation can be performed. As a surgical measure, it is used to control pain or a disease process in the affected limb such as malignancy, infection or gangrene. It varies between 60% and 110% so lower levels of activity and mobility would be expected[4]. The hamstrings and quadriceps may then be sutured together over the distal end of the femur – a technique called a myoplasty. ladybessviernes, UDM PT Students. Amputation should only be considered if the limb is non-viable (gangrenous or grossly ischemic, dangerous, malignancy or infection), or non-functional[2]. Artif Limbs. Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. The tibia is dissected using an oscillating saw – optimum length of residual bone is approximately 12-17cm[11]; the tibia should be beveled at approximately 45° to remove the sharp anterior edge, the fibula should ideally be approx. In this situation an amputation is performed as the limb does not have any blood supply beyond the level of injury and is therefore deemed non-viable. There are a number of injury severity scores that may be used in conjunction with clinical investigations to establish the likelihood of limb salvage. Guest F, Marshall C, Stansby G. Amputation and rehabilitation. Read more, © Physiopedia 2021 | Physiopedia is a registered charity in the UK, no. The muscles are transected and the bone is sawed through with an oscillating saw. The ISO/ISPO classification of congenital limb deficiency. Spires MC, Kelly BM, Davis AJ, editors. This amputation is done through the tibia and fibula, measurements are taken and flap lines marked out. sarcoma (cancer of the connective tissue), Trauma (limb buried under / crushed by heavy object, limb damaged by car accident, stabbing, gunshot, animal bite etc. Read more, © Physiopedia 2021 | Physiopedia is a registered charity in the UK, no. Some of the most common complications associated with amputation include; See here, for more detailed information on post-operative complications following an amputation. In order to minimise the risk of neuropathic pain (see complications) the nerves are dissected on tension so the end will retract back into the tissues where they can heal away from the stump end. Less often, it results from vascular disease and complications of diabetes. Preferred flap technique of surgeon is then used to close the wound and create functional stump - options include skew flap, long posterior flap, sagittal flap or medial flap.

Original Editor - The Open Physio project. Can be performed on below-knee or above-knee amputation. [1] by trauma, prolonged constriction or surgery (see Pathology leading to amputation). Very short trans-femoral stumps often end up in abduction because there is an imbalance between the adductor and abductor muscles. In some cases, an amputation is carried out on individuals as a preventative surgery for such problems and other people are born with amputations due to congenital disorders (see Paediatric limb deficiency). A special case is that of congenital amputation, a congenital disorder, where fetal limbs have been cut off by constrictive bands. Demos Medical Publishing; 2013 Dec 19. Limb Loss Definitions. They are likely to be a wheelchair user, some are considered for a trunk and contralateral ischial tuberosity weight-bearing prosthesis. Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. Suitability for a prosthesis - if the patient is likely to be a candidate for prosthetic rehab the level of amputation needs to be carefully considered. Orthopaedics and Trauma. In some cases, it is carried out on individuals as a preventative surgery for such problems. Please find below links to more detailed pages on the management of amputees, Through the pelvis to warm the arteries (contraindicated in patients with arterial insufficiency because the warmth leads to increased metabolism, causing a greater demand for nutrients, which are not available). The risks for wound complications and mortality with this type of amputation is very high. There is a significantly higher level of energy expenditure on the part of an amputee. This method prevents deformity of the residual limb by preventing the excessive shift of the muscle during contraction (when this happens it interferes with the muscle control in the prosthesis).

Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). The surgeon dissects through the skin to then isolate and ligate the nerves and blood vessels. There are a number of different investigations that can be carried out to assess the need for amputation; these examinations assess the bones and soft tissues to establish limb viability. Available at. Buerger Allen's Exercise. That is usually the journal article where the information was first stated. The optimum length of the residual bone is approximately 7.5-10cm proximal to the superior border of the patella. Pre-Fitting Management of the Patient with a Lower Limb Amputation, Clinical Guidelines: Mental Health Amputees, http://en.wikipedia.org/w/index.php?title=Amputation, http://www.merriam-webster.com/medlineplus/phocomelia, http://www.youtube.com/watch?v=jQUFmOmX35o, http://www.youtube.com/watch?v=_lBkrLZ4PGo, http://www.youtube.com/watch?v=T1SA_6hzTxQ, https://www.physio-pedia.com/index.php?title=Amputations&oldid=225662, Arterial insufficiency leading to death or decay of body tissue (gangrene), Infection e.g. There is a range of different prosthetics available for the upper limb; these range from hooks to passive orthotics that might mainly serve an aesthetic purpose to fully mechanical and functional limbs. These investigations will help the surgeons to find out if the blood supply to the limb is intact. Distal stabilisation of the muscles is recommended, allowing for effective muscle contraction and reduced atrophy. Bone infection (Osteomyelitis), Malignant tumours e.g. A decision to amputate a limb should be made through discussion with the interdisciplinary team - including the patient - wherever possible; in an emergency situation, the decision should be made based on medical need. Devinuwara K, Dworak-Kula A, O'Connor RJ. this is the most common lower limb amputation, great toe amputation affects balance, and ambulation because the late stance phase of gait and push off is disrupted without a first toe/ray to act as the final point of weight transfer, the second toe acts as lateral support to the great toe and amputation of the second toe may lead to halux valgus, the transverse arch of the foot get affected with the removal of any toe, usually amputated through the proximal phalanx, toe amputations should not be performed through the joint because it will expose the avascular cartilage, The first ray along with great toe amputations affects balance and gait negatively, amputation of the 2nd through 4th ray disrupts the transverse arch because the ligamentous structure is removed, single ray amputations decrease the "structural integrity of the arch", when the fifth ray is resected it negatively impacts gait during midstance to terminal stance because it changes the rollover action of the foot, when there is infection surgeons can leave the wound open, usually due to wounds in the forefoot due to gangrene or infection, a guillotine amputation is sometimes done in order to rid the foot of infection, dorsal split-thickness grafts on the plantar aspect of the foot are used instead of skin grafts because it is more resilient, the dorsal contact area of the foot is decreased and this leads to an increase of pressure and may result in calluses, ulcers, and wounds, stance and gait (forward propulsion) is negatively influenced because the lever arm of the foot is shortened, plantar flexion contracture should be avoided - this may occur because of the gastroc-soleus strength dominance over the dorsiflexors, if the wound is well healed, the patient can have excellent function, these 3-type of amputations are mainly performed in children to preserve the length of the residual limb and to keep the epiphyseal plate intact, equinus varus foot deformity is possible due to the following: a gastrox-soleus and dorsiflexor imbalance, as well as a shortened lever arm, surgical techniques to prevent this deformity include Achilles Tendon lengthening and the "reattachment of the peroneal and anterior tibial muscles to the more advantageous biomechanical position", Range of prosthetic options such as insoles, toe fillers or ankle-foot orthosis (exception for ankle disarticulation), Can lead to skin breakdown and joint pain, Cosmesis might be not accepted by the patient, Preservation of the knee joint leads to less energy expenditure and better proprioception than an above knee amputee, Candidates for patella tendon bearing prosthesis, Near the normal level of function (more energy expenditure than a non-amputee), Decreased mortality rate and increases the likelihood for ambulation of the older person when compared to the above-knee amputation population, May need ‘bone bridge’ surgery due to distal fibula pain (, Long lever prevents contractures and allows consequently the movement control, Proprioception and better distribution of pressure, Poor cosmesis as knee mechanism is distal to the knee joint (see complications), More demanding surgical procedure with the risk of increased wound complications, better muscular balance while preserving the strength of the adductors, candidate for ischial tuberosity bearing prosthesis, weak adductor muscles, causing a severe imbalance, the position of the stump often ends up in flexion and abduction, causes massive energy expenditure (effort) and the prosthesis can be heavy. Hip disarticulation is amputation of the whole lower limb through the hip joint. Amputations below the knee. Physiotherapy Stump or Residual Limb Wrapping. When refering to evidence in academic writing, you should always try to reference the primary (original) source. 1173185. [8], Myoplasty: Attaching sectioned muscles to opposing muscles [9]. Gait Training with C-Leg®: Sitting Down and Standing Up. If left untreated this can lead to gangrene or infection and amputation is needed to avoid this becoming life-threatening. Hip Disarticulation: 11.83: Shoulder Disarticulation: 5.00: Above-Elbow: 3.55: Below-Elbow: 1.45: Hand.70: How is BMI interpreted? Prosthetics and Orthotics International 1991; 15: 67-69. MedlinePlus. The surgeon dissects through the skin to then isolate and ligate the nerves and blood vessels. The lower limb is supplied by the popliteal artery which subdivides into the: In vascular disease these arteries can become blocked or narrowed over time which reduces the circulation to the legs; this can cause pain, ulceration and blackened areas. Day HJB. Purpose Arms, legs, hands, feet, fingers, and toes can be amputated.

Moore. In this regard, amputation surgery may be considered a reconstructive surgery, with results similar to amputation of an arthritic femoral head and prosthetic replacement (total-hip replacement)[3]. Amputation is the removal of an extremity by trauma, prolonged constriction, medical illness or surgery. Cylindrical stump (fibula 5-10 mm shorter), Long posterior muscular flap covering the distal end, attached ventrally to a shorter anterior flap (ventral suture). Cosmesis - length and shape of stump affect the aesthetic appearance. Wheeless’ Textbook of Orthopaedics: Below Knee Amputation. ); in some cases leading to, myodesis: the muscles and fascia are sutered directly to the distal residual bone for better prosthetic control, myoplastic: suture to opposite muscle in the residual limb to to each other and to the periosteum or to the distal end of the cut bone for weight bearing purposes, Skin flaps: skin should be mobile, sensation intact, no scars, Muscles are divided 3 to 5 cm distal to the level of bone resection, Nerves are gently pulled and cut cleanly, so that they retract well proximal to the bone level to reduce the complication of neuroma, If a leg has been amputated because of gangrene, the remaining leg is examined for a puls, Doppler ultrasound (occlusion of vessels), Bypass grafts (autogenous graft uses a vein to bypass the obstructed area), Stimulates collateral blood flow in the patient’s leg, The leg is elevated until the toes go white, then lowered, then level, Repeat 2-3 times to improve collateral circulation, Therapist stands on the amputation side, using a belt around the patient’s waist to support, Maintain function in the remaining leg and stump to maintain peripheral circulation, Maintain respiratory function (important with smokers and those patients under general anaesthesia), For hygiene and skin care see handout on amputations, A hip flexion contracture may develop because of elevation to reduce swelling, Stump bandaging is done to ‘cone’ the stump, thereby preventing oedema, which occurs because there is no muscle pump and the stump hangs, Swelling must be prevented to allow proper attachment of the, The stump sock is put on first, then the prosthesis, The prosthesis must be cleaned and maintained (children who are still growing, grow out of their prostheses). in a car accident, gunshot wound or blast. A hip disarticulation results most often from trauma, tumors and severe infections, such as necrotizing fasciitis (commonly referred to as flesh-eating bacteria). Fact Sheet. Initially, the arterial and venous supply are ligated to prevent hemorrhage (bleeding). Examples of this include: Once a decision has been made to remove part of a limb the level of amputation needs to be decided; this can have significant consequences so there are a number of factors to take into account when planning the surgery: Myodesis: The muscle is secured to the bone by suturing the distal tendon via pre-drilled holes to the bone. A well-planned and executed amputation can remove a painful, dysfunctional limb and allow rehabilitation with a prosthetic limb to a functional, painless state. A traditional hip disarticulation is done by separating the ball from the socket of the hip joint, while a modified version retains a small portion of the proximal (upper) femur to improve the contours of the hip disarticulation for sitting.
