The importance of pathogenic bacteria in venous leg ulcers was analysed in a randomized open trial divided into 2 parts. During the first 2-week period the effects of physiological saline and dextranomer beads were compared. During the following 8 weeks the effect of porcine skin, aluminium foil and a double layer bandage were compared. The assessment of the results of treatment was based on the area and volume of the ulcer measured by stereophotogrammetry and the bacteriological findings. Staphylococcus aureus was the commonest isolated species. Mixed cultures comprising Staph. aureus and gram-negative bacteria were the next commonest finding. There was a low frequency of isolation of anaerobic bacteria. The bacteriological findings were similar in the different treatment groups. The nature of the bacterial isolates and the colonization estimated by a contact-transfer procedure bore no relationship to the clinical assessment as to whether the ulcer was clean or purulent. Healing of the ulcer was not influenced by the bacteria present. The findings seem to indicate that as a rule the bacteria in the ulcers are saprophytic and will disappear when the favourable environment for their growth is lost.

“…The projection error which is caused when the naturally curved body surface is projected onto the flat image plane of a camera may be avoided by stereophotogrammetry. Bulstrode et al (1986) and Erikson et al (1979 and1984) take two photographs of the lesion using a specialized stereocamera that is both camera and projector. After taking the photographs and processing the film, the resulting transparencies are placed in the camera again.…”

The lack of an accepted method of accurate and objective measurement of wound dimensions is a major obstacle to the assessment of effective wound management regimes. This paper addresses the problems associated with wound measurements and introduces a new instrument based on the principle of coded structured light. The instrument projects a sequence of parallel stripes of light onto the surface of the lesion. These patterns are observed by a video camera which is linked to a computer system where the images can be stored and processed. Using the positions of the focal points of the camera and the stripe projector, the computer calculates a three dimensional map of the observed scene by triangulation. This map is then used to reconstruct the original, healthy skin surface by cubic spline interpolation. The area of the reconstructed surface is the area of the wound. Its volume is sandwiched between the measured and the reconstructed surface. The system also calculates the depth and the circumference of the wound. The instrument measures the volume of the wound with a precision of about 5 per cent provided that the ratio of volume to area is greater than 4 mm.

“…The other function of wound assessment is to acquire data that permits comparison of wounds, either from observations made in the same wound on different occasions, or comparisons of different wounds, as in clinical studies of wound treatment or wound healing. While the information needed to fulfil the requirements of the basic clinical examination can be gleaned from the observation of a number of purely subjective variables, that required for comparative studies must be objective and reproducible (3,13). No review of the methods available for the clinical assessment of open wounds in human subjects appears to have been published previously and this paper aims to describe those available and indicate potential difficulties in their use and interpretation.…”

ABSTRACT. This review describes the methods that may be used clinically for the assessment of open wounds and indicates potential limitations in their usefulness. None of the methods available for the appraisal of wounds in human subjects measures healing directly but a number of objective variables may be used to shed light on the healing process. Research methods have been suggested that may be clinically useful in assessing healing but are not generally available at present.
