title: Low success rate of non-intervention after breakage of interlocking nails.
abstract: We followed 12 patients with nailed femoral shaft fractures in which breakage of the static locked nail occurred during fracture treatment. Only two fractures united. The remaining ten fractures had to be treated with exchange nailing after a median of 10 (4-14) months. Nine fractures healed after a median of 5 (4-7) months and one was lost to follow-up. Although breakage of a proximal static reamed femoral locked nail may imitate the effect of dynamisation, the success rate is low. Early exchange nailing is a more successful option to achieve fracture union.
