Distraction osteogenesis is a predictable method for restoring missing tissue prior to implant placement. However, pull from the soft tissue can alter the desired direction of the distraction. This article describes and illustrates techniques that are useful for maintaining the desired vector during alveolar distraction osteogenesis. These methods can prevent the need for further intervention a...

We report the results of distraction osteogenesis (callotasis) for the reconstruction of extensive defects after the excision of skeletal tumours in the limbs. Bone transport was performed in ten patients (five osteosarcomas and five giant-cell tumours), shortening-distraction in three (two osteosarcomas and one Ewing's sarcoma), and distraction osteogenesis combined with an intramedullary nail...

Distraction osteogenesis is a method of forming bone through osteotomy and sequential stretching of the healing callus. This process is accomplished with the aid of a distraction device, which is secured with screws placed directly into bone for a predetermined length of time. This clinical report describes the use of distraction osteogenesis to treat mandibular asymmetry in a patient with Gold...

BACKGROUND The treatment of patients with partially atrophic rib and rib defects requires an ideal arc of the rib that has adequate bone length and width. To design and assemble a distraction device with a strain gauge, we need to establish an animal model for testing it during rib distraction osteogenesis. METHODS Osteotomies were performed at the same position in the fifth rib in 8 rabbits....

Distraction osteogenesis is increasingly used for bone lengthening of facial skeleton. Distractors may be intraoral and extraoral. The authors present development of distractors and their use for treatment of facial bones. Procedure may be used for treatment of malformations, syndroms, posttraumatic bone defects and deformities. The advantage of a distractor are a simple and fast procedure, sho...

PURPOSE The aim of this study was to assess the efficacy of alveolar vertical distraction osteogenesis and autogenous bone grafting in terms of bone gain, bone resorption, and implant survival and success rates and investigate the relationship between bone gain and resorption after alveolar vertical distraction osteogenesis. MATERIALS AND METHODS A systematic search was done using MEDLINE, EM...

Successful performance of distraction osteogenesis requires rigorous patient compliance with a daily activation regimen of a percutaneous screw. Previous clinical studies have found that failure of patient compliance with this regimen is the most common complication leading to technical failure of the distraction process. The authors have developed an internalized spring-mediated device for man...

AIM To investigate the effects of radiotherapy on distraction osteogenesis performed on the same bone in an area that has not received radiation. Radiotherapy (Co60) was carried out in a region where tumors may develop, and then, on the assumption that the tumoral region had been removed, distraction osteogenesis was carried out, and the effects were investigated. METHOD Thirty New Zealand ra...

Introduction: The Ilizarov method of distraction osteogenesis is a valuable tool for the treatment of segmental long bone defects. Successful treatment depends on stability of fixation; viability of the vascular supply and marrow cavity; rate, frequency and latency of distraction; and adequacy of consolidation. Several reports have described the induction of a prolonged hypervascular state duri...
