The below-the-knee amputation for vascular disease.

Of 190 consecutive patients with below-the-knee amputation done for diabetic or arteriosclerotic vascular disease, 167 were successfully fitted with a prosthesis and used the prosthesis in some or all of the activities of daily living. The surgical failure rate was 4.2 per cent; only eight patients required surgical revision to a higher level of amputation. The technique of rigid plaster dressing followed by delayed application of a plaster cast and pylon was not detrimental to wound healing and did not increase the interval between surgery and the use of the prosthesis, nor did it depress the eventual level of function. When compared with our own previous experience with other flaps, the long posterior flap offered a significant advantage in healing rate.     

Lower-extremity amputation: a 6-year follow-up study in Brazil

PURPOSE: To evaluate the 6-year mortality in 50 patients following lower-limb amputation. METHODS: The cumulative survival rate of 50 (28 men, 22 women) amputees aged 54 to 94 years (mean, 67.3; median, 73.5) was retrospectively studied from 1993 to 1998. Indications for above- or below-knee amputation were trauma (n = 2), vasculitis (n = 2), and critical ischaemia of the lower limbs (n = 46). Leg amputation was performed after anamnesis, physical examination, and angiography. All patients were followed up for 6 years by phone or domiciliary visit. A death certificate was verified when a patient was lost to follow-up. Statistical analysis was expressed by the actuarial survival curve. RESULTS: Of 50 amputees, 36 died in the 6 years following leg amputation: 22 in the first year, 3 in the second year, 5 in the third year, 2 in the fourth year, 2 in the fifth year, 2 in the sixth year; 14 remained alive after 6 years. CONCLUSION: Patients who underwent lower-limb amputation had a high 6-year mortality. Most deaths occurred in the first year.     

Rehabilitation after lower limb amputation: a comparative study of above-knee, through-knee and Gritti-Stokes amputations

A study of 169 unilateral amputees under three Disablement Services Centres was performed. The study comprised 88 above-knee, 54 through-knee and 27 Gritti-Stokes amputations. Satisfactory rehabilitation occurred in 33 per cent of above-knee, 62 per cent of through-knee and 44 per cent of Gritti-Stokes patients (56 per cent overall). The better rehabilitation of through-knee versus above-knee amputees (P less than 0.02) was also found in a group of patients matched for comparable age and duration of amputation as well as in a group of age-matched vascular amputees. Through-knee amputees relied significantly less on wheelchairs than above-knee (P = 0.016) and Gritti-Stokes (P = 0.05) amputees. The prosthesis used for the through-knee and Gritti-Stokes amputations was considered unsightly in 50 per cent of cases (versus 31 per cent for the above-knee prosthesis). The superior rehabilitation with through-knee amputations should prompt us to improve both our technique for this amputation and the prostheses currently available. A through-knee amputation should be performed in preference to an above-knee amputation in the case where either is surgically possible, and a below-knee amputation not feasible.     

Role of Gritti-Stokes amputation in peripheral vascular disease.

The perigenicula lower limb amputations performed for peripheral vascular disease in Nottingham between April 1987 and September 1992 were reviewed. Of the 434 amputations, 173 were below-knee amputations (BKA), 144 Gritti-Stokes amputations (GSA) and 117 above-knee amputations (AKA). The 30-day mortality was significantly greater for AKA patients than either GSA or BKA patients. There was no difference in mortality within 30 days of amputation between GSA and BKA. Re-amputation rate to a more proximal level was significantly higher in BKA compared with GSA. Mobility after prosthetic rehabilitation was assessed using the Stanmore grading. A greater number of patients achieved mobility grade III and above in the GSA and BKA groups when compared with the AKA group, but there was no significant difference between GSA and BKA groups. At follow-up, a median of 23 months after amputation, there was a tendency for more patients to have given up using their limb prosthesis in the GSA group than either the BKA or AKA groups. However, there remained no significant difference between the BKA and GSA groups in the numbers of patients who remained successfully rehabilitated to Stanmore grade III or above. When a BKA is not possible, GSA offers a better prospect for rehabilitation compared with AKA in patients with occlusive arterial disease.     

Transmetatarsal amputation in patients with peripheral vascular disease.

Transmetatarsal amputation has the reputation of being an operation with a poor healing rate, and less than a 50% success rate had recently been reported. The outcome of this amputation in patients with peripheral vascular disease has been retrospectively studied in this paper by examining 34 transmetatarsal amputations performed over a 5-year period. Twelve patients had had previous toe amputations and 22 were diabetic with an overall healing rate of 68%. There was no significant difference in the success rate between diabetics and non-diabetics. One patient died in the postoperative period, giving an early post-operative mortality of 3%. Revision of failed transmetatarsal below-knee amputation resulted in healing in seven patients out of nine, suggesting that it does not compromise later amputation at a higher level. Healing did not appear to be influenced by factors such as sympathectomy, previous arterial reconstruction or peripheral pulses. Transmetatarsal amputation provides patients who have a short life expectancy with a durable functional stump which is prosthesis free.     

Ring finger ray amputation: a 25-year follow-up.

The treatment of class III ring avulsion injuries remains controversial. This case report presents a 25-year follow-up of a class III ring avulsion injury treated with secondary ring finger ray amputation. This case shows long-term excellent functional and cosmetic results of ring finger ray resection without bony transposition.     

Changing pattern of lower limb amputation for vascular disease

In 1980 a review of lower limb amputation over a 3.5 year period between 1974 and 1978 was reported from our centre. More recently 193 amputations were performed for peripheral vascular disease over a similar 3.5 year period, representing an increase of 33 per cent in the amputation rate during the last 6 years. This cannot be explained by the increasing age of the population alone. Fewer below-knee amputations (BKA) (33.0 per cent) and more Gritti-Strokes amputations (GSA) (32.0 per cent) were performed and the overall incidence of re-amputation for stump breakdown was 13.5 per cent. Twenty-eight per cent of below-knee amputation stumps required re-amputation at higher levels, but when successful were associated with a 75 per cent incidence of rehabilitation with an artificial limb. Eight per cent of GSA stumps required re-amputation and were associated with a twenty-eight per cent incidence of successful rehabilitation. Thirty-seven per cent of patients had undergone reconstructive vascular surgery before amputation. Of the 26 patients requiring re-amputation 58 per cent had undergone arterial reconstruction in an attempt to salvage the limb (chi 2 = 5.65, P less than 0.02) and in 26.9 per cent of cases this was performed within the week before amputation. We feel that injudicious attempts at arterial reconstruction, when amputation appears inevitable, may adversely affect the subsequent level of amputation and jeopardize rehabilitation.     

Recovery after amputation for arteriosclerosis. Follow-up study]

Clinical follow-up of 71 patients subjected to major amputation of the lower extremities for atherosclerotic arteriopathy has been analysed for the purpose of ascertaining real possibilities of functional recovery and quality of life. Research results show that only a small number of patients (38%) can achieve an acceptable quality of life. The reasons have been identified in the objective difficulty of adequate physical and psychotherapeutic rehabilitation owing to structural shortcomings or the presence of associated pathology or the advance in the basic condition which does not permit application or frustrates results.     

Major lower limb amputation following failed infrainguinal vascular bypass surgery: a prospective study on amputation levels and stump complications.

The effect of failed vascular bypass surgery on final amputation level and stump complications is the subject of debate. The aim of this prospective cohort study was to assess the influence of previous infrainguinal bypass surgery on amputees in the authors' centre. Over a three-year period, 234 amputations (219 patients) were performed for critical ischemia. The cause of ischemia was either peripheral obstructive arterial disease (POAD) or diabetes mellitus (DM). Forty-eight percent (48%) (113 amputations) had ipsilateral vascular bypass surgery prior to amputation and 52% (121 amputations) had not. Final amputation level and the post-operative complications of infection, significant stump pain and delayed wound healing were used as the outcome measures for this study. At the end of the study period these outcome measures were used to compare the influence of previous bypass surgery on the two groups of amputees. There was a significantly higher rate of transfemoral amputations (TFA) (32.7%) vs. 16.5%; p < 0.05) and stump infection rate (42% vs. 23%; p < 0.05) in the bypass group. Significant stump pain (p = 0.23) and delayed wound healing (p = 0.24) was more prevalent in the bypass group although statistical significance could not be demonstrated.

Vocational reintegration after a lower limb amputation: a qualitative study

The objectives of this study were to describe the process of job reintegration, to obtain more detailed information about workplace adjustments, and to assess the positive and negative experiences of amputees (in the Netherlands) who returned to paid work after their lower limb amputation. The study had a retrospective design with semi-structured interviews. The authors used a qualitative methodology to obtain detailed information on the reintegration process. Thirty-two (32) subjects participated with a mean age of 42.6 years. The mean time between amputation and return to work was nearly one year (11.5 months). The most common reasons for delay in return to work were stump problems and problems in wound healing. Fifty percent (50%) of the amputees got different work tasks or another job than before amputation, mainly because of physical restrictions caused by the amputation. The most important motives of the amputees for job reintegration were work as a form of day spending (69%) and social contacts at the workplace (66%). Bad support of the implementing body which takes care of job reintegration and employer (34%) were the most mentioned obstacle to job reintegration. Vocational workers should be regular members in the rehabilitation teams for amputees.     

A multivariate analysis of determinants of wound healing in patients after amputation for peripheral vascular disease

In a prospective study 53 patients undergoing amputations of the lower limb were evaluated for clinical criteria, laboratory results, pulse volume recordings, Doppler pressures, Photoplethysmographic Skin Perfusion Pressures (PPG/SPP) and angiography. The purpose of the study was to analyse which of these techniques predicts wound healing adequately after amputation. Forty-five patients eventually completed all tests. With the exception of PPG/SPP none of these tests were able to predict skin healing. The technique of PPG/SPP proved very reliable in helping to select the level of amputation, if measured anteriorly (P = 0.0001, r = 0.83). Angiographic scoring also correlated significantly (P = 0.0016) with a successful result. This study suggests that surgeons should not rely on their clinical acumen for the selection of the amputation level. In the absence of a reliable non-invasive test, angiography may well be useful but PPG/SPP will enable the surgeon to amputate on an optimal level and thus reduce complications and improve rehabilitation.     

Factors influencing the early outcome of major lower limb amputation for vascular disease.

A consecutive series of 349 primary lower limb amputations for vascular disease, done during 1992-1998, were reviewed for amputation level, revision, complications and death, seeking associations with the American Society of Anesthesiology (ASA) grade and pre-operative co-morbidities of patients. Attempted revascularisation, and seniority of surgeon supervising the amputation were also examined for their possible influence on outcome. There were 312 patients (163 male) aged 39-92 years (median, 76 years). The majority of patients were ASA 3 or 4 (76%), and ASA 4 was associated with increased mortality (P < 0.01). Limiting heart problems (P < 0.01) and 'general frailty' (P < 0.001) also carried significantly higher risks of death, but limiting chest problems, dementia, and diabetes mellitus did not. There was no significant association between attempts at revascularisation at any time before amputation, and amputation level or the need for revision. There were no differences between consultants, registrars, and senior house officers (most senior surgeon) for any outcome measure. This study documents the medical status of amputees more clearly than usual, and demonstrates the effect of co-morbidity on the substantial mortality of these patients. The results support an aggressive policy of attempted revascularisation, and show that properly trained junior surgeons obtain satisfactory results.
