To evaluate the radiographic and clinical outcomes of a systematic approach to exchange nailing for the treatment of aseptic femoral nonunions previously treated with an intramedullary nail.
Tertiary referral center.
Fifty aseptic femoral nonunions in 49 patients who presented with an intramedullary nail in situ an average of 25 months after the initial fracture nailing were evaluated.
Our systematic approach includes inserting an exchange nail at least 2 mm larger in diameter than the in situ nail, using a different manufacturer's nail, static interlocking, correction of any metabolic and endocrine abnormalities, and secondary nail dynamization in cases showing slow progression toward healing.
The outcome measures were radiographic and clinical evidence of nonunion healing and time to union.
All 50 femoral nonunions (100%) healed after this systematic approach to exchange nailing. The average time to achieve union was 7 months (range, 3–26 months).
Utilization of this systematic approach of exchange nailing for the treatment of aseptic femoral nonunions resulted in a 100% healing rate.
