Abstract — Problems with skin integrity can disrupt daily prosthesis use and lead to decreased mobility and function in individuals with lower-limb loss. This study reviewed the literature to examine how skin problems are defined and diagnosed and to identify the prevalence and types of skin problems in individuals with lower-limb loss. We searched the literature for terms related to amputation and skin problems. We identified 777 articles. Of the articles, 90 met criteria for review of research methodology. Four clinical studies met our selection criteria. The prevalence rate of skin problems was 15% to 41%. The most commonly reported skin problems were wounds, abscesses, and blisters. Given the lack of standardized definitions of skin problems on residual limbs, we conclude this article with a system for classification.
Key words: amputation, epidemiology, lower-limb loss, prosthetic limb, rehabilitation, residual limb, review, skin diseases, skin integrity, skin problems.
Problems with skin integrity can disrupt the daily use of a prosthetic limb and interfere with the independence and lifestyle of individuals with lower-limb loss. Biomechanical factors involved in the interaction between a prosthetic limb and skin interface, including distribution of weight, shear force, moisture, and temperature, can lead to skin problems [1-3].
Skin problems associated with prosthetic limb use are common. While a range of skin diagnoses, such as allergic contact dermatitis, epidermal hyperplasia, malignancies, and ulcerations, have been described [4], we found no consistency in the literature regarding how these problems are reported. Accordingly, we do not know the epidemiology of the residual-limb dermatologic issues faced by individuals with lower-limb loss. A recent literature review [5] cited only one study [6] with sufficient rigor to ascertain a prevalence of 16 percent for skin problems on the residual limb. However, the skin problems reported in that study were limited to abscesses and ulcers, a narrow subset of the whole spectrum of dermatologic issues that could affect prosthetic limb use and user satisfaction.
As a first step toward filling this gap in knowledge, we undertook a systematic review of the literature to better define the prevalence and types of skin problems on the residual limb related to prosthetic use. We use this information to propose a classification system that may be of use in future clinical studies.
We searched the literature published through 2008 using four databases: MEDLINE, EMBASE, CINAHL, and RECAL. MEDLINE is a biomedical database containing publications since the 1950s. EMBASE is a biomedical and pharmacological database containing publications since 1988. CINAHL is a nursing and allied health database containing publications since 1982. RECAL is an orthotics and prosthetics database containing publications from 1900 to 2007. Table 1 shows medical subject headings (MeSH) and free text words that we used to search MEDLINE, CINAHL, and EMBASE. MeSH are standardized terms defined by the National Library of Medicine and arranged in a hierarchical structure that allows searching at various levels of specificity. In RECAL, we used the free text words "skin" and "amputation" (MeSH not available). We restricted our search to the English language and humans in MEDLINE and EMBASE and to the English language in CINAHL (option to limit to human research not available).
We reviewed the title and abstract of all publications identified in our literature search. We selected articles if they discussed skin problems in adults (Š18 years old) with lower-limb loss (transtibial, transfemoral, or knee disarticulation, but not foot, ankle, or hip disarticulation) who were fitted with a prosthesis. We excluded articles that discussed wound healing immediately postamputation. We removed duplicate articles obtained from different databases.
Our second selection process involved reviewing study research methodology. We selected articles if they included a description of the inclusion and exclusion criteria and the study population, identified the reason for amputation, identified the level of amputation, and reported both the prevalence and types of skin problems on a residual limb associated with prosthetic limb use. We excluded all case studies, case series, reviews, expert opinions, and letters to editors. We also excluded articles published before 1990 or with a sample size of fewer than 40 subjects.
Lastly, we reviewed the reference lists of these articles for publications related to skin problems in individuals
with lower-limb loss (transtibial, transfemoral, or knee disarticulation). Relevant articles published after 1990 underwent the second selection process we mentioned previously.
Our initial search using MeSH and free text words yielded 777 articles: 313 from MEDLINE, 233 from EMBASE, 31 from CINAHL, and 200 from RECAL (Table 2). Our first selection process yielded 71 publications: 50 from MEDLINE, 5 from EMBASE, 3 from CINAHL, and 13 from RECAL (Table 2). We found an additional 19 related articles published after 1990 in the reference lists. We then reviewed the study methodology of the resulting 90 articles and retained 2 publications from MEDLINE and 2 from the reference lists (Table 2).

RESULTSOur initial search using MeSH and free text words yielded 777 articles: 313 from MEDLINE, 233 from EMBASE, 31 from CINAHL, and 200 from RECAL (Table 2).

We then reviewed the study methodology of the resulting 90 articles and retained 2 publications from MEDLINE and 2 from the reference lists (Table 2).
The 86 articles we excluded included 41 case reports or case series; 16 reviews or expert opinions; 4 letters to editors; 2 duplicated articles; and 7 articles about topics not of interest, including novel treatments for skin problems, quality of life, shear force, or no reported skin problems. We also excluded an additional two articles: one article (with the exception of its abstract) was written in Korean and the other, although referenced in another study, was unpublished. The remaining 14 articles we excluded were clinical studies discussing skin problems in individuals with limb loss. Four studies discussed both upper- and lower-limb amputations [7-10], one of which
was published before 1990 [7]. Ten cross-sectional and cohort studies about lower-limb loss did not meet our selection criteria because of insufficient sample size [11-12], the presence of nonadult participants [13-17], missing selection criteria [14], failure to report the prevalence of skin problems [14,18], or lack of skin problem specification [12,17,19-20].
Table 3 identifies the four publications that met our selection criteria, representing research performed in the Netherlands, Canada, the United States, and Singapore from 1990 to 2008 [6,21-23]. All the studies were cross-sectional and obtained data through either a chart review or a questionnaire delivered by mail or telephone. A physician assessed skin problems in three out of the four studies; the last study was by patient self-report [23]. The most common reasons for amputation were vascular disease, diabetes, and trauma. The most common amputation level was transtibial.
The overall prevalence of skin problems ranged from 15 to 41 percent, with increasing prevalence in the more recent studies. The most commonly reported skin problems (Š20%) were wounds (including ulcers), abscesses, and blisters. The articles did not specify the method of skin problem assessment (i.e., physical examination, laboratory data, or biopsy).
DISCUSSIONWe found one systematic literature review about skin problems in individuals with lower-limb loss that reviewed the literature published through 2002 [5]. We used similar methodological assessment criteria, including an assessment of the inclusion and exclusion criteria, a description of the study population, and the prevalence rate of skin problems. We added several criteria, including the level of amputation, the reason for amputation, and a description of types of skin problems. These additions allowed us to narrow our focus to lower-limb amputations, better characterize the study populations, and describe the types of skin problems commonly reported in the literature.
The limited number of cohort studies (n = 4), none of which met our inclusion criteria, identifies an area for future research. Because of the inherent limitations of a cross-sectional study, including the inability to obtain an incidence of skin problems and to infer causality of factors that may lead to skin problems, we recommend that future studies answer these questions by using more rigorous study designs.

None of the clinical studies included a definition or standardized method of assessment for skin problems, thus making it difficult for us to describe and categorize the common types of skin problems in individuals with lower-limb loss. In the literature, some studies consider perspiration and hygiene problems as factors leading to skin problems [2], whereas others categorize these precursor conditions as skin problems themselves [11,14,18]. Some studies reported using patch testing and swab testing to clarify the underlying etiology of skin problems [13], whereas others did not report how the skin problems were assessed and subsequently diagnosed [15,22]. Description of skin problems varied across studies and depended on the person reporting the skin problems (patient vs physician), with more detailed descriptions provided by physicians. The lack of standardization made it difficult for us to accurately compare the prevalence rates of skin problems across studies and to describe the most commonly occurring skin problems. Differing skin problem prevalence rates may also be attributed to the etiology of the amputation or the country of study.
Our study is limited to reviewing the existing literature (1990-2008) about individuals with lower-limb loss. We did not include unpublished studies, those with a sample size of fewer than 40 subjects, or those written in languages other than English. To the best of our knowledge, this study comprehensively reviews the literature that exists on skin problems in individuals with lower-limb loss. In addition to completing a search inquiry in four databases, we also reviewed reference lists to ensure that we did not miss relevant studies.
We recommend that future classification of lower-limb problems on the residual limb be categorized according to either morphology or etiology rather than with generalizations (e.g., "rash" or "wound"). Hygiene problems, odor, and sweating should be considered precursors to skin problems. We propose a classification schema as shown in Tables 4 and 5, in which the same skin conditions are included regardless of classification strategy. Standardized definitions of skin problems will allow clinicians and researchers to report the prevalence and types of skin problems on residual limbs with improved external validity and reliability.
CONCLUSIONSWe conclude that the prevalence of skin problems in individuals with lower-limb loss from 1990 to 2008 was 15 to 41 percent; the most commonly reported skin problems were wounds, abscesses, and blisters. The prevalence and types of skin problems reported varied by study and their respective method of assessment and definition of skin problems. We recommend that future studies use the standard dermatology definitions for skin-problem classification as described in Tables 4 and 5. We also recommend a standardized assessment of an individual's residual limb at regular intervals so that comparisons may be made across studies and the causality of skin problems may be better inferred. Through such studies, we will better understand skin problems in individuals with lower-limb loss and effectively devise prevention and intervention for this significant problem.
