Epidemiology of Limb Amputations and Prosthetic Use During COVID-19 Pandemic in the Netherlands.

OBJECTIVE: To evaluate the trends in the incidence of major limb amputations and the prevalence of Dutch prosthetic users at the national level in The Netherlands between 2012 and 2021 (during the COVID-19 pandemic). Local hospitals in The Netherlands reported a doubling of major lower limb amputations during COVID-19, information about a change in the incidence of major upper limb amputations was not reported. We could not confirm this remarkable increase in major lower limb amputations in our institution, nor did we observe a change in the incidence of major upper limb amputations. We hypothesize that the COVID-19 pandemic had no effect on the number of major limb amputations. DESIGN: Observational retrospective study analyzing national open-access databases of health insurance claims. SETTING: The Dutch national opensource database www.opendisdata.nl was used to retrieve the incidence of limb amputations in the period 2012-2021, stratified by the level of amputation and the cause of amputation. The results were verified using the www.gipdatabank.nl databank. This period included 4 intervals of nationwide COVID-19 lockdowns. PARTICIPANTS: 60,848 patients who underwent limb amputations at the upper or lower extremity in the Netherlands from 2012 to 2021 (N=60,848) were included in this study. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Upper- and lower-limb amputation and prosthetic use. RESULTS: Data were retrieved for a total of 60,848 patients in the Netherlands, who underwent 68,180 amputations of the upper and lower extremities at any level from 2012 to 2021, including 22,095 major amputations of the lower extremities. The ongoing trend of stable numbers of major lower-limb amputations from 2012 to 2019 continued in 2020 and 2021. The verification of these data at the level of prosthetic users confirmed that the annual trends were unchanged. CONCLUSION: The reported increased numbers of major lower-limb amputations during the COVID-19 pandemic in the Netherlands could not be confirmed using nationwide epidemiologic data.

[Analysing gait in the GP's consulting room]. / Observatie van lopen in de huisartsenspreekkamer.

Gait disorders are often seen in the general practitioner (GP)'s consulting room. Orthopaedic or neurological problems may lead to abnormalities in gait. A careful analysis is important to advice or refer the patient for additional diagnostics or treatment. Basic gait analysis can be performed on any patient by applying a systematic stepwise observation. This is illustrated here by three case reports. This observation starts by looking at parameters such as walking speed, safety, efficiency etc. Analysis of biomechanical pattern such as step frequency, stride length and a detailed analysis of the different joint movements during the stance and swing phase can subsequently be performed. This observation will be helpful for the GP, guiding further examinations of function level such as mobility, strength, or balance and resulting in adequate advice to the patient or referral for additional diagnostics or treatment.

Short and long term mortality rates after a lower limb amputation.

OBJECTIVE: To determine mortality rates after a first lower limb amputation and explore the rates for different subpopulations. METHODS: Retrospective cohort study of all people who underwent a first amputation at or proximal to transtibial level, in an area of 1.7 million people. Analysis with Kaplan-Meier curves and Log Rank tests for univariate associations of psycho-social and health variables. Logistic regression for odds of death at 30-days, 1-year and 5-years. RESULTS: 299 people were included. Median time to death was 20.3 months (95%CI: 13.1; 27.5). 30-day mortality = 22%; odds of death 2.3 times higher in people with history of cerebrovascular disease (95%CI: 1.2; 4.7, P = 0.016). 1 year mortality = 44%; odds of death 3.5 times higher for people with renal disease (95%CI: 1.8; 7.0, P < 0.001). 5-years mortality = 77%; odds of death 5.4 times higher for people with renal disease (95%CI: 1.8; 16.0,P = 0.003). Variation in mortality rates was most apparent in different age groups; people 75-84 years having better short term outcomes than those younger and older. CONCLUSIONS: Mortality rates demonstrated the frailty of this population, with almost one quarter of people dying within 30-days, and almost half at 1 year. People with cerebrovascular had higher odds of death at 30 days, and those with renal disease and 1 and 5 years, respectively.

An ICF-based education programme in amputation rehabilitation for medical residents in the Netherlands.

BACKGROUND AND AIM: Education programmes of the International Society for Prosthetics and Orthotics (ISPO) are directed primarily at prosthetists and orthotists. In a multidisciplinary setting, greater attention should be given to other professionals working in the field of amputation, prosthetics and orthotics. This includes, among others, physiotherapists, occupational therapists and residents and physicians from orthopaedics, vascular surgery and physical medicine and rehabilitation (PM&R). The aim of this paper is to describe the education programme in amputation and prosthetics for residents in PM&R in the Netherlands. The programme is based on concepts of the International Classification on Functioning, Disability and Health (ICF). TECHNIQUE: This narrative paper presents the amputation and prosthetics education programme for residents in PM&R in the Netherlands. The programme is based on two models: the ICF and the Canadian Medical Education Directives for Specialists (CanMEDS). DISCUSSION: ICF core sets for amputation and prosthetics need further development. Subsequently, the application of these core sets can help stimulate the education of residents in PM&R, and other multidisciplinary team members who work in amputation rehabilitation. CLINICAL RELEVANCE: Through this education programme, residents work closely with other team members using the common language of the ICF, enhancing treatment and technical advice in amputee care.

[Examination of the shoulder]. / Onderzoek van de schouder.

Examination of the active and passive range of motion of the shoulder joint is of major importance when diagnosing shoulder disorders. Abduction and external exorotation movements of the shoulder joint can be judged reliably. Limitations in the range of abduction indicate subacromial pathology and limitations in the range of external exorotation indicate glenohumeral pathology. Other shoulder joint movement tests have only low inter-rater reliability. Palpation of the shoulder serves no useful purpose if inspection of the joint and examination of the active range of motion reveal no abnormal signs. The value of physical examination tests that identify impingement or stability of the shoulder joint has not been reliably demonstrated.

[Physical examination of the knee after trauma]. / Onderzoek van de knie na een trauma.

The practice guideline 'Traumatic knee complaints' from the Dutch College of General Practitioners is aimed at differentiating between intra-articular and extra-articular lesions. The diagnosis is based mainly on a combination of patient history and a limited physical examination of the knee. Specific tests for hydrarthrosis, injuries to the collateral or cruciate ligaments, and meniscal pathology have only a low diagnostic accuracy. Few reliable studies have been conducted into the diagnostic value of specific tests; most studies employed poor methodology, had considerable inter-observer variation and produced widely heterogenous results. Inspection of the knee can provide information regarding the presence of fluids in the knee (hydrarthrosis or haemarthrosis). A restricted active range of movement in flexion and extension may indicate osteoarthritis or arthritis.

The mobility scale for lower limb amputees: the SIGAM/WAP mobility scale.

PURPOSE: To translate the SIGAM mobility scale into the Dutch language and to test and validate its properties in everyday practice. METHOD: The SIGAM mobility scale as published by Ryall et al. was translated into the Dutch language with the local used verbs for prosthetic use. The translated Dutch text was reviewed by several authors and a panel of professionals. The retranslation by a native speaker was reviewed by the original author who suggested modifications. The Dutch trial version of the mobility scale was presented to a panel of prosthetic users and therapists who advised slight modifications for better understanding of the questionnaire. IN training sessions prosthetic teams across The Netherlands were trained in the use of the translated SIGAM/WAP mobility scale. RESULTS: During the translation there were problems with slang words and the use of specific words in the care of amputee patients. The instruction of team members and the test scoring of the questionnaire and the algorithm showed no difficulties. There was good to perfect agreement between scores in case training sessions with perfect inter observer reliability. CONCLUSIONS: With this instrument we have a specific measurement tool in the English and Dutch language to measure mobility in lower limb amputees.

Shoe adaptation after amputation of the II - V phalangeal bones of the foot.

In The Netherlands, about 50% of all amputations of the lower limb are toes and forefoot amputations. Traumata of toes and mid-foot are rare. Preservation of the foot is the primary goal for treatment. Crush injuries of the foot may be associated with prolonged morbidity. This case study presents an insole solution for the solitary first phalangeal bone after amputation of the phalangeal bones II - V. The normal adaptation for forefoot amputations is stiffening of the sole of the shoe and a rocker bar to improve the toe off phase with load reduction of the forefoot. Because the patient had to do excessive stair climbing during work another solution was chosen. As a foot orthosis, a metal soleplate was made in order to have free movement during loading and toe-off during walking. The soleplate gives safety and provides self-adjusting properties after toe off. This enables the shoe technician to make a shoe without a rocker bar or an extra stiff insole. The 0.5 mm custom-made spring-steel plate is also used as a protective in industrial safety shoes. To improve shoe adaptation more research and case reports have to be published in order to inform doctors and shoe technicians about everyday solutions to partial foot amputations.

Mobility of people with lower limb amputations: scales and questionnaires: a review.

OBJECTIVE AND DESIGN: A systematic literature review to compare mobility scales used for lower limb amputees. A literature search was carried out by computerized search of biomedical literature including Medline and Embase. The studies included were published between 1978 and 1998 and including the following keywords: amputation, artificial limbs, prosthesis, lower limb, activities of daily living, mobility. RESULTS: Thirty-five studies were identified; 19 had a measurement of separate levels of mobility comparable to each other. Sixteen studies used ordinal and ratio scales without separate levels of mobility. The widest range of measurement found was the scale from 'walking with prosthesis without a walking aid' to 'totally confined to bed'. The Stanmore Harold Wood mobility scale was published most frequently. None of the 35 studies presented give a continuous measurement of mobility. CONCLUSION: A multitude of measurement scales and questionnaires are available for differ in methods and measuring range. Measuring mobility by a scale has been shown to have limitations. Several authors did extensive research but they all measure only a number of aspects of mobility. Consensus about the measurement of mobility of lower limb amputees is not available in the recent literature.

A study of technical changes to lower limb prostheses after initial fitting.

There is little published material in recent years about the use of lower limb prostheses in an elderly amputee population. In this study the authors were interested in the technical changes to lower limb prostheses after a first limb fitting procedure in a post-rehabilitation population in The Netherlands. The process of fitting a prosthesis and the technical changes to the artificial limb in the first year afterwards are studied.

Epidemiology of lower limb amputees in the north of The Netherlands: aetiology, discharge destination and prosthetic use.

The aim of this study was to give a retrospective review of all lower limb amputations performed in the 3 northern provinces of the Netherlands in 1991-1992. Assembled data were compared with the existing information in the National Medical Register (NMR) over the same period. With the participation of all regional hospitals, 473 lower limb amputations from transpelvic to transmetatarsal level were identified. Of the amputations 94% were performed for vascular pathology, 3% for trauma, and 3% for oncologic reasons. After surgery a prosthesis was provided to 48% of the amputees. The actual number of performed amputations exceeds the number of amputations registered by the NMR by 9%. Incidence rates of lower limb amputations in the Netherlands are 18-20/100,000 over the last 12 years. These numbers are lower than in other areas and no sharp decrease in frequency compared with other countries in Western Europe.

Clinical rehabilitation of the amputee: a retrospective study.

The aim of this study was to determine the rehabilitation outcome of lower limb amputee patients after clinical rehabilitation. Altogether 183 amputee patients admitted for clinical rehabilitation in the years 1987-1991 were reviewed by retrospective analysis of medical record data. Three groups of amputee patients were identified by reason for amputation. The vascular group: (N = 132), mean age 67 years, mean admission time 119 days, 85% prosthetic fitting. The oncology group (N = 15), mean age 55 years, mean admission time 77 days, 60% prosthetic fitting. The traumatic amputee group: (N = 14), mean age 41 years, mean stay 134 days and 100% prosthetic fitting. Some 22 patients were bilateral amputees and were assessed separately. The most important reasons for not fitting a prosthesis were oncological metastases, stump and wound healing problems. After rehabilitation 86% of all patients could be discharged home. These results are more favourable than those seen in previous studies.
