What is Recorticalization After Bifocal Internal Bone Transport in the Double-plated Sheep Femur about?

## Abstract Distraction osteogenesis and bone remodelling after the end of bone transport were investigated in one femur each of six adult male sheep. A newly designed internal distraction device was used. A custommade osteosynthesis plate was fixed on the lateral side of the femur, and two transporting plates driven by a transcutaneously inserted screwdriver moved two bone cylinders simultaneously over a 40 mm defect. An additional plate was applied ventrally to stabilize the device. Bone transport was begun 2 weeks postoperatively at 1 mm/day at each transporting plate until they came into contact. New bone formation within the distraction gaps was evaluated by computed tomography scans and was quantified at 4 and 6 months by dual energy x‐ray absorptiometry as well as histomorphometry on polyfluorochrome‐labelled undecalcified ground sections and microradiographs. At 4 months, all distraction gaps were bridged by abundant newly formed bone trabeculae, which were reduced and condensed to cortex‐like layers of new bone at 6 months. Less new bone was always found under the lateral device than in the unplated medial and dorsal segments, but the amount of new bone under the ventral p
