The timing of flap coverage, bone-grafting, and intramedullary nailing in patients who have a fracture of the tibial shaft with extensive soft-tissue injury.

The cases of forty-three patients who had a Type-IIIB open fracture of the tibial shaft were reviewed to determine the effect of treatment of the soft-tissue injury on the rate of major complications. An infection developed in two of the eleven patients who had had early muscle-flap coverage compared with ten of the nineteen who had been managed by open care of the wound and nine of the thirteen who had had later flap coverage. Patients who had had bone-grafting after complete re-epithelialization of the wound, regardless of the method of closure, had a lower rate of early infection (none of sixteen compared with four of fifteen) and an earlier average time to union (fifty-four compared with sixty-three weeks) than those in whom the wound was not completely closed or was draining at the time of bone-grafting. Delayed intramedullary nailing with reaming was associated with a high rate of infection (nine of nineteen patients), regardless of the condition of the soft tissue at the time of nailing. In our opinion, adequate débridement and early assessment of the soft-tissue defect are necessary so that appropriate soft-tissue coverage can be provided within the first one to two weeks. When the soft-tissue portion of the injury is addressed promptly and definitively and then allowed to heal completely, secondary osseous reconstruction may proceed with fewer complications.
