Background: There are a wide variety of non surgical treatment and surgical options available such as spica casting, traction followed by casting, plate fixation and flexible intramedullary nails for femur diaphyseal fractures in children. There is no clear consensus as to the ideal treatment. Methods: We report our experience with a prospective comparative study involving 120 cases of femoral diaphyseal fractures treated with DCP and TENS with follow up of over a period of three years. Outcome was assessed with criteria of Flynn et al1. At the end of second and third year Harris hip score2 was applied to assess the functional outcome. Results: Out of the hundred and twenty cases 96 had middle / 3rd fractures. Mean age was 10.85__ampersandsignplusmn; 2.26 years. Time taken for toe touch walking and union time for Group-I (DCP) and Group-II (TENS) were 7.85__ampersandsignplusmn;2.23 __ampersandsignamp;17.90__ampersandsignplusmn;5.09 weeks and 3.97__ampersandsignplusmn;1.68 __ampersandsignamp; 13.00__ampersandsignplusmn;1.37 weeks respectively. Nine cases in Group-I and 6 cases in Group-II had limb length discrepancy and there were 6 cases with coronal plane angulation in Group-II. Functional outcome was better in Group-II at the end of one year. But the functional outcome at the end of second and third year of both the groups was similar. Conclusion: Even though long term functional outcome of both procedures are similar, TENS has several statistically significant advantages over DCP in relation to patient morbidity. Hence a better choice of implant for pediatric femoral diaphyseal fractures.
