Male or female subjects, 18 years and above, undergoing hip, knee or spinal surgery with an
expected hospital stay for 4 days or more will be included in the trial. Individual trial
duration will be for 7 days (follow-up). Two hundred subjects will be included in the trial,
i.e. 100 subjects per arm. The treatment arm (either new or standard wound dressing) will be
assigned by randomization stratified by type of surgery (i.e. hip, knee or spine).
