Abstract
Purpose: We set four objectives: compare compression plate with locking screw, assess bone graft usefulness, assess utility of resection and compression of fracture site, and determine prognostic factors.
Materials and methods: A multicentre study was carried out including Sant Pau, Valle de Hebròn and IMAS hospitals in Barcelona. 54 surgical cases treated from 1994 to 2003 were included for retrospective study. Three groups of factors were analysed: familial, factors associated with the initial trauma and those associated with the surgical procedure. We studied the statistical relation to consolidation, consolidation time and postoperative complications.
Results: The following factors significantly enhanced consolidation (p< 0.05): treatment with nail in atrophic pseudoarthrosis and plate in hypertrophic. Consolidation time was significantly shortened (p< 0.05) if fractures were initially simple (type A) and for those initially treated conservatively. Postoperative complications were reduced (p< 0.05) in fractures that were initially simple (type A).
Conclusions: There were no differences between the two implants studied in terms of consolidation, consolidation time and complications. However, cases of atrophic pseudoarthrosis had a better outcome with nails and the hypertrophic cases with plates. Bone grafts did not improve results. Compression of the fracture site was a determining factor in achieving consolidation; therefore, open intramedullary nailing should be performed to this end. Simple fractures and fractures initially receiving conservative treatment were good prognostic factors following pseudoarthrosis surgery.
