We present our experience with elastic stable intramedullary nailing (ESIN) used in the single bone fixation of both bones forearm fractures in children. From May 2002 to July 2004, 20 children (14 boys and 6 girls), median age of 10 years (range 6-15 years) were treated with ESIN for 16 closed and 4 grade I open forearm fractures. All patients were reviewed clinically at a median follow-up of 20 months (range 6-30 months). All fractures were radiologically united at a median of 6.7 weeks (6-9 weeks). The median operating time was 35min (range 25-60min). The median hospital stay was 2 days (range 1-3 days). Removal of the nails was undertaken in all 20 children at a median of 19 weeks (range 16-24 weeks) post-operatively. At follow-up, a full range of elbow and wrist movements were found in all cases. There was no clinically significant rotational deformity in any case. ESIN seems to be a safe method in the treatment of single bone fixation of both bones forearm fractures in children between 6 and 15 years of age.
