“…Entretanto, muitos desses autores têm relatado alta taxa de complicações e necessidade de procedimentos cirúrgicos após a técnica do transporte ósseo (5,(8)(9) . Para evitar essas complicações, os tecidos desvitalizados (ósseo e partes moles) do local da pseudartrose devem ser ressecados, seguindo-se o encurtamento agudo (compressão imediata) no foco e o subseqüente alongamento gradual do membro (4,6) .…”

“…A malalignment of the fragments can lead to an insufficient fracture healing and a loss of limb function [1]. Fractures of long bones are commonly reduced with distraction osteogenesis using external fixators [2], [3], [4]. A nowadays widely-used concept for distraction osteogenesis was developed by Gavriil A. Ilizarov [5].…”

Purpose The correct rotational alignment of a fractured long bone is an important step in the fracture reduction process. In order to plan the fracture reduction and the appropriate external fixation, plain radiographs are conventionally used. But as three-dimensional information of the complex situation is not available, the correct amount of rotation can only be approximated. Thus, the objective of this study is to develop a system to assess the rotational relationship between proximal and distal fragments of the tibia and femur based on a set of two calibrated X-ray radiographs.Methods In order to robustly determine the rotational alignment of proximal and distal bone fragments, a 2D/3D reconstruction approach was employed to reconstruct the fractured bone fragments. Two different studies were performed to evaluate the accuracy of the complete system for the purpose of fracture reduction.Results The reconstruction accuracy was evaluated in terms of major bone axis and in-plane rotational alignment. The long bone axis of the femur and tibia could be derived an average with an error of 0.33 ± 0.27 • , while an average inplane rotational error of 2.27 ± 1.76 • and 2.67 ± 1.80 • was found for the proximal and distal fragment, respectively. The overall mean surface reconstruction error of tibial fragments was 0.81 ± 0.59 mm and 1.12 ± 0.87 mm for femoral fragments.Conclusions A new approach for estimating the rotational parameters of fractured bone fragments has been proposed. This approach is based on two conventional radiographs and 2D/3D reconstruction technology. It is generally applicable to the reduction of any simple long bone fracture and could provide an important means for external fracture fixations.

We report the use of distraction osteogenesis for segmental mandibular regeneration. This technique has been used in thousands of patients in the Soviet Union to regenerate as much as 30 cm of tubular bone in the extremities. However, we are unaware of previous experimental or clinical reports of segmental mandibular regeneration by distraction osteogenesis. In a canine model, 2.5-cm segmental mandibular defects were filled with regenerate bone in 25 days at a rate of 1.0 mm/d using bifocal distraction osteogenesis. The diameters of the regenerate segments were comparable with preexisting mandible, and all animals resumed normal oromandibular function following regeneration. The regenerate bone was evaluated radiographically, angiographically, and histologically. In the control group without distraction osteogenesis, the segmental defects failed to fill with regenerate bone. The theoretical basis for distraction osteogenesis, a detailed description of the technique, and a review of previous studies on experimental mandibular lengthening are presented.
