This is a prospective randomised controlled comparative study comparing bone transport through induced membrane (BTM) and conventional bone transport (BT) in management of bone defects in infected non united fractures of long bones of lower limbs (femur, tibia) as regard clinical, functional outcomes and possible complications.
A prospective randomised controlled study was conducted at Ain shams university hospitals. A total of 30 patients with infected non united fractures of long bones of lower limbs (femur and tibia) were divided randomly into 15 patients treated by bone transport through induced membrane technique (BTM) (Group A) and 15 patients treated by conventional bone transport technique (BT) (Group B)

| External fixation index | calculated by dividing the EFT (months) by the bone defect size (centimeters) | through study completion, an average of 1 year |
| Docking time | time taken (months) from end of bone transport till union of docking site (both with and without bone graft) | through study completion, an average of 1 year |
| Association for the Study and Application of the Method of Ilizarov (ASAMI) Scoring System | scoring system for bone and functional results | through study completion, an average of 1 year |
| complications rate | number of complications in each group | through study completion, an average of 1 year |
| additional operations | number of additional operations in each group | through study completion, an average of 1 year |
