A technique to measure the tension across a wound in real time during wound closure

The optimal result after primary closure of a wound, if wound eversion and low tissue tension is maintained, is a flat inconspicuous and robust scar that heals in a timely fashion. If the tension applied during wound closure is too high and the sutures are too tight, blood supply to the site may be compromised resulting in wound breakdown. If the tension applied is too little, the subcutaneous tissues and dermal edges will not be opposed effectively, leading to poor scar formation.
