The medical sector is a wide and complex field that needs continuous improvements in its efficiency. This paper deals with the problem of collaboration and the data sharing in the medical field. The focus is on the case of treatment processes requiring prosthesis implant. Several actors from both medical and industrial sectors are involved in these processes. They need to collaborate during the whole process of prosthesis creation and implantation. From this perspective, this paper presents a discussion about the advantages of the current PLM-based approaches to deal with these issues. A first proposal of the conceptual approach is also proposed.
