Major limb amputations in a tertiary hospital in North Western Nigeria

Determinant Causes of Limb Amputation in Ethiopia: A Systematic Review and Meta-Analysis

Background

Most amputees suffered from lack of rehabilitation services and went on streets as glorified beggars. However, there is a paucity of information about determinant causes of amputation in Ethiopia. Therefore, this systematic review and meta-analysis was conducted to estimate pooled prevalence of limb amputation and its determinant causes in Ethiopian population.

Methods

Worldwide databases such as PubMed/MedLine, Web of Science, CINAHL, Embase, Scopus, and Science Direct were searched to retrieve pertinent articles. Grey literatures were also looked in local and national repositories. Microsoft excel was used to extract data which were exported to stata version 14.0 for analysis. Cochrane Q and I2 tests were used to assess heterogeneity. Egger's and Begg's tests were employed to assess reporting biases. Random effect meta-analysis model was applied to estimate pooled prevalence.

Results

Twenty-one qualified studies with 18,900 study participants were reviewed. Pooled prevalence of limb amputation was 31.69%. Lower extremity amputation (LEA) accounted for 14.41%, and upper extremity amputation (UEA) took 10.53% (6.50, 14.53). Above knee amputations (2.50 %) were common orthopedic operations whereas ray amputations (0.03%) were the least orthopedic procedures of LEA. Above elbow amputations (2.46%) were common from UEA while shoulder disarticulations (0.02%) were the least orthopedic surgical procedures. The major causes of limb amputations were trauma (11.05%), diabetic foot ulcer (9.93 %), traditional bone setters (24.10%) and burn (10.63%).

Conclusions

Lower extremity amputations were common orthopedic surgical procedures. Major determinant causes were trauma, diabetic foot ulcer, traditional bone setters and burn.

Indications and complications of lower extremity amputations in two tertiary hospitals in the North West Region of Cameroon

Introduction

the study aimed to outline the common indications and complications of lower extremity amputations among amputated patients in two tertiary hospitals in the North West Region of Cameroon.

Methods

this hospital based retrospective study was conducted in the Bamenda Regional Hospital and Mbingo Baptist Hospital over a 5-year period from 2015-2019. We identified and reviewed amputee´s medical records over the 5-year period. A well designed extraction form was used for data collection and the data obtained was analysed using Epi-info version 7.2.4.

Results

a total of 148 patients underwent 159 amputations in Bamenda Regional Hospital and Mbingo Baptist Hospital with a mean age of 54.28 years (SD ±19.28). Males out-numbered females with a ratio of 2: 1. The most common indication for lower extremity amputation was Diabetic foot gangrene (42.14%) followed by trauma (22.01%). The most frequently performed procedure was Below Knee Amputation (48.42%). Post-amputation complication rate was recorded at 40.25% with surgical site infection being the most common (25.8%). Mortality rate was recorded at 6.28%.

Conclusion

diabetic foot gangrene is the leading indication of lower limb amputation in our setting and the most frequently performed procedure is Below Knee Amputation with surgical site infection being the most common complication.

Low-cost body-powered prosthesis for transfemoral amputation

To allow an amputee resume healthy walking, a well-designed lower limb prosthesis is required. However, in many developing countries, the cost of high-tech and often imported prosthesis is out of the financial reach of many amputees. The objective of this study was to design and implement a mechanical, body-powered transfemoral prosthetic device to help transfemoral amputees regain functional ambulation. The materials used include socket adapter, acetone hardener, plaster of Paris bandages, perlite lining, and polyester resin. Using anthropometric measurements of a volunteer amputee, a user-friendly and ergonomic transfemoral prosthetic device was designed using AutoCAD rendering and fabricated using engineering methods such as casting and welding. The prosthetic limb consists of a polypropylene socket, a galvanised iron knee joint with a hinge and spring suspension system, and a perlite foot. An evaluation of the prosthetic limb after fabrication showed that it restores the ambulatory function of the amputee.

Contribution of diabetes to amputations in sub-Sahara Africa: A systematic review and meta-analysis

Diabetes related amputations remain a major global problem, with devastating complications. We critically appraised relevant literature to quantify the prevalence of diabetes related amputations in sub-Saharan Africa (SSA). An electronic search was performed using the EMBASE and PubMed databases until 2020. Twenty-four out of 834 studies retrieved were included. The pooled prevalence of diabetic-related amputations was 36.9% (95%CI: 32.9%-40.8%). Complications of diabetes related amputations included infection, anaemia, foot deformity and mortality. The study revealed a substantial contribution of diabetes to the burden of amputations in SSA and suggests the need for further studies to assess how to reduce the incidence of diabetes, reduce the incidence of and or delay the progression of macro and microvascular complications of diabetes in SSA.

Diabetic foot ulcer disease in African continent: 'From clinical care to implementation' - Review of diabetic foot in last 60 years - 1960 to 2020

The prevalence of diabetes mellitus is increasing globally and the greatest potential increases in diabetes will occur in Africa. Data suggest that these increases is associated with rapid demographic, sociocultural and economic transitions. There will be a parallel increase in the complications of diabetes and among the various complications those related to diabetic foot disease are associated with the highest morbidity and mortality. Diabetic Peripheral neuropathy (DPN) is the most common cause of diabetic foot complications in African countries; however, peripheral arterial disease (PAD) appears to increase, possibly a result of rising urbanization. Search done for the past six decades (1960 to 2020) on all foot complications. Rates of complications of diabetic foot in last six decades varied by country as follow: DPN: 4-90%; PAD: 0-77%; foot ulcers: 4-61%; amputation rates: 3-61% and high mortality rates reaching to 55%, patients who presented late with infection and gangrene. Educational and prevention programmes are required to curb the growing complications of diabetic foot ulcers in Africa among patients and health care workers. Secondly, it is imperative that governments across the African continent recognise the clinical and public health implications of diabetic foot disease in persons with diabetes.

Through-knee versus above-knee amputation for vascular and non-vascular major lower limb amputations

BACKGROUND

Diabetes and vascular disease are the leading causes of lower limb amputation. Currently, 463 million adults are living with diabetes, and 202 million with peripheral vascular disease, worldwide. When a lower limb amputation is considered, preservation of the knee in a below-knee amputation allows for superior functional recovery when compared with amputation at a higher level. When a below-knee amputation is not feasible, the most common alternative performed is an above-knee amputation. Another possible option, which is less commonly performed, is a through-knee amputation which may offer some potential functional benefits over an above-knee amputation.

OBJECTIVES

To assess the effects of through-knee amputation compared to above-knee amputation on clinical and rehabilitation outcomes and complication rates for all patients undergoing vascular and non-vascular major lower limb amputation.

SEARCH METHODS

The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, and CINAHL databases; the World Health Organization International Clinical Trials Registry Platform; and the ClinicalTrials.gov trials register to 17 February 2021. We undertook reference checking, citation searching, and contact with study authors to identify additional studies.

SELECTION CRITERIA

Published and unpublished randomised controlled trials (RCTs) comparing through-knee amputation and above-knee amputation were eligible for inclusion in this study. Primary outcomes were uncomplicated primary wound healing and prosthetic limb fitting. Secondary outcomes included time taken to achieve independent mobility with a prosthesis, health-related quality of life, walking speed, pain, and 30-day survival.

DATA COLLECTION AND ANALYSIS

Two review authors independently reviewed all records identified by the search. Data collection and extraction were planned in line with recommendations outlined in the Cochrane Handbook for Systematic Reviews of Interventions. We planned to assess the certainty of evidence using the GRADE approach.

MAIN RESULTS

We did not identify RCTs that met the inclusion criteria for this review.

AUTHORS' CONCLUSIONS

No RCTs have been conducted to determine comparative clinical or rehabilitation outcomes of through-knee amputation and above-knee amputation, or complication rates. It is unknown whether either of these approaches offers improved outcomes for patients. RCTs are needed to guide practice and to ensure the best outcomes for this patient group.

Evolving Indications for Lower Limb Amputations in South Africa Offer Opportunities for Health System Improvement

BACKGROUND

Rapid urbanization and westernization have precipitated dramatic changes in the profile and prevalence of surgical diseases in sub-Saharan Africa. Disease of lifestyle is now common. We aimed to review our experience with lower-limb amputations at our surgical service in South Africa.

METHODS

A single-center retrospective review of a prospectively collected database was performed of all patients who underwent a lower limb amputation. Inferential and descriptive statistics were performed. Patient demographics, indication, type of amputation, and management were reviewed. The primary outcome was 30-day in-patient mortality rate.

RESULTS

Over a 5-year period (2013-2018), 348 patients underwent lower limb amputations. The median age was 61.5 years. 53.7% were diabetic and 56.3% were hypertensive. 53.2% had associated peripheral vascular disease and 8% preexisting cardiac disease. 30.7% smoked. Guillotine below-knee amputation was frequently performed (44.5% of amputations). 16.1% of these patients required a further operation. The in-hospital mortality rate was 8%. Underlying renal disease was an independent risk factor for mortality (p = 0.004).

CONCLUSION

Currently, the most common indications for LLA in South Africa are diabetes mellitus and atherosclerosis. This reflects the changing pattern of disease in the country. There is a major problem with access to health care in rural areas in South Africa with significant delays in getting patients to tertiary units for evaluation by specialists. Foot care and prevention at a primary health care level is also lacking. Global improvements in the healthcare system are needed to improve LLA rates in South Africa.

The prevalence and risk factors for phantom limb pain in people with amputations: A systematic review and meta-analysis

Background

Phantom limb pain (PLP)—pain felt in the amputated limb–is often accompanied by significant suffering. Estimates of the burden of PLP have provided conflicting data. To obtain a robust estimate of the burden of PLP, we gathered and critically appraised the literature on the prevalence and risk factors associated with PLP in people with limb amputations.

Methods

Articles published between 1980 and July 2019 were identified through a systematic search of the following electronic databases: MEDLINE/PubMed, PsycINFO, PsycArticles, Cumulative Index to Nursing and Allied Health Literature, Africa-Wide Information, Health Source: Nursing/Academic Edition, SCOPUS, Web of Science and Academic Search Premier. Grey literature was searched on databases for preprints. Two reviewers independently conducted the screening of articles, data extraction and risk of bias assessment. The meta-analyses were conducted using the random effects model. A statistically significant level for the analyses was set at p<0.05.

Results

The pooling of all studies demonstrated a prevalence estimate of 64% [95% CI: 60.01–68.05] with high heterogeneity [I² = 95.95% (95% CI: 95.10–96.60)]. The prevalence of PLP was significantly lower in developing countries compared to developed countries [53.98% vs 66.55%; p = 0.03]. Persistent pre-operative pain, proximal site of amputation, stump pain, lower limb amputation and phantom sensations were identified as risk factors for PLP.

Conclusion

This systematic review and meta-analysis estimates that six of every 10 people with an amputation report PLP–a high and important prevalence of PLP. Healthcare professionals ought to be aware of the high rates of PLP and implement strategies to reduce PLP by addressing known risk factors, specifically those identified by the current study.

Evaluation of the quality of life in individuals with amputations in relation to the etiology of their amputation. A case-control study

Objectives: Several studies indicate that limb amputations have a negative influence in the quality of life of those individuals who underwent amputation surgery. The aims of this study were to evaluate the quality of life in Mexican individuals with limb amputations compared with a control group, to identify demographic and clinical differences related to the etiology of the amputation, and to determine if they are associated with the quality of life observed in these patients. Methods: All participants were recruited from the Hospital "Dr Gustavo A. Rovirosa Pérez". The quality of life of all participants was evaluated using SF-36. Results: Individuals with amputations of vascular or trauma etiology, showed a diminished health-related quality of life when compared with the control group (p < .001). We observed that individuals with amputations due to trauma were younger, mostly single, with more upper limb amputations and with a shorter period since amputation at the current assessment in comparison to individuals with amputations. Conclusions: Although limb amputation represents a surgical procedure necessary to preserve the life of a person, our results support that it negatively impacts the health-related quality of life of these individuals. Regardless of the etiology of the amputation, rehabilitation programs are primarily focused on reintegrating individuals to their everyday life. However, these programs may have poor results when patients have a poor quality of life. Therefore, quality of life assessment and early inclusion in programs that aim to improve the quality of life of individuals with amputations should be always taken into consideration.

Pattern of limb amputations in Liberia

Background:

Amputation is one of the oldest known surgical procedures. It has been one of the modalities of applying judgment and treatment. Its method and indications has evolved over time. Modern amputation is regarded as a part of treatment rather than failure of treatment. Amputation is the removal of a limb or part of a limb through on or more bone. When through a joint is referred to as disarticulation. Data on the profile and pattern of amputation in Liberia will add to the body of knowledge.

Aim and Objectives:

Is to describe the pattern of limb of amputations in Liberia. Also to describe the anatomical variations of limb amputations in Liberia.

Patients and Method:

A retrospective study of all patients that underwent limb amputation surgeries in the John F Kennedy Memorial (JFK M), Hospital, Monrovia Liberia between January 2010 to December 2015.

Results:

100 patients had limb amputations between 2010 and 2015. Males(73) to female(27) ratio were 2.4:1. The age range was 9 - 91 years. Mean age was 42.9 years. The indications for amputations were Trauma 24%, Diabetes 29%, Gangrene (6%), Chronic ulcer (25%), Tumour (5%). Below knee(47%), Above Knee(45%), Below elbow(2%), Above Elbow(2%), Knee Disarticulation(2%), and Big Toe Disarticulation(2%).

Conclusion:

The profile of Limb amputation in Liberia is not very different from what is obtaining in the region. However the limitations of histology and other investigative procedure have affected the accurate diagnosis of certain conditions like tumours.
