RÉSUMÉ
The controversy about whether to do reamed or nonreamed interlocking nail in the treatment of femoral shaft fractures was the stimulus to do this research work. The material included 20 cases of closed femoral fractures managed at the orthopedic department of Daman-hour National Medical Institute from february/1999 to february/2001,10 cases managed by non reamed interlocking nail and 10 cases managed by reamed interlocking nail with a follow up period[clinically and radiologically at regular interval] at least 1 year post operative .Method of assessment according to the score of Thoresen et al [1985] where excellent and good are satisfactory and fair and poor are un-satisfactory. The results were satisfactory significantly in reamed group, where radiological union was evident earlier, external rotation malunion was less and range of knee motion was better in statistical significant results
