What is primary and secondary intention healing?
Primary wound healing occurs e.g. after a surgical incision in which the edges of the wound are connected by a suture. In general, such wounds will heal within 6 – 8 days. In contrast, in secondary wound healing the wound cannot be closed by a primary wound closure.
