Three Part Question
In [patients with pretibial flap lacerations] is [a primary skin graft or simple wound edge approximation] better at [reducing the time to healing]?
A 69 year old woman has slipped and caught her leg on a chair. She attends your A&E department with a large flap laceration to the anterior aspect of her right leg. She has no other injuries, no other significant past medical history and has good social support. you want her wound to heal quickly so that she may get back to her normal activities as soon as possible. You wonder whether a primary split skin graft or a simpler procedure using the existing flap would be best to achieve this.

Earlier studies only compared primary split skin grafting with grafting after failed conservative management or studied conservative management alone. This study shows that primary split skin grafting under local anaesthetic shortens the time to full healing of pretibial flap lacerations by nearly four weeks though a larger prospective randomised controlled trial would be needed to confirm this. Early mobilisation has been shown to be beneficial in the elderly after such a procedure which makes management as an out-patient the preferred option.
Clinical Bottom Line
A primary split skin graft performed under local anaesthetic significantly reduces the healing time for pretibial flap lacerations and can be done successfully as an out-patient procedure.
