The convexity class

Abstract

A survey of the time interval between injury and operation in relation to the type of wound healing, whether per primary or secondary intention, reveals that no definite time limit can be demonstrated with regard to primary wound healing. Healing per primary union occurred after debridement carried out 11 and 12 days following injury, even in the presence of a discharging sinus as evidenced by cases 2.1.10 and 2.1.11. In case 2.1.14 the original scalp wound in the left frontal region was closed and already granulating when, six weeks after injury, the wound was re-opened and a frontal abscess evacuated. A soft rubber drain was removed after four days and did not interfere with primary healing of the wound.
