title: Application of locking plate in long-bone atrophic nonunion following external fixation.
abstract: The treatment of atrophic fracture nonunion continues to represent a therapeutic challenge. Large segmental osteopenia is often seen in patients who received uniplanar or hybrid external fixators as the definitive method of fixation for high-energy fractures, and this adds more difficulties to the treatment of fracture nonunion. This retrospective study was designed to assess the outcome of locking compression plating with autologous bone grafting in patients with long-bone atrophic nonunion following external fixation.From January 2004 to December 2009, a series of consecutive patients with atrophic nonunion of the long bone following external fixation were treated with this method in our institution. The clinical outcomes and complications of these patients were retrospectively analyzed. Twenty-seven patients with 28 fracture nonunions were involved in this study. Mean follow-up was 14.2±3.4 months. Bony union was achieved in all 27 patients within a mean 18.6±4.8 weeks after revision surgery. Two patients developed superficial wound infections. No deep infections were found, and no implant failure was seen. Three patients reported minor pain in the donor site of the bone graft, and no other donor site complications were found.Revision osteosynthesis of long-bone atrophic nonunion following external fixation by locking compression plating with autologous iliac crest bone grafting represents a safe and efficacious modality for the treatment of these challenging conditions.
