It is important not to close the volar fascial compartments tightly. In order to avoid compartment syndrome, insert just a few sutures to approximate the muscles.
Subcutaneous tissue and skin should be closed by interrupted sutures. In certain instances, for example with marked forearm swelling, one of the wounds may have to be left open (usually the radial approach, as the ulna is subcutaneous). There are different techniques to overcome these difficulties (e.g., elastic closure, vacuum-assisted closure, petroleum jelly gauze, skin substitute, etc.)
