BACKGROUND Currently, the common treatment for femoral nonunion with large segmental bone defect is difficult and complex. The effective surgical methods are rare, include vascularized bone grafting, Masquelet technique and Ilizarov distraction osteogenesis. The objective of this study is to investigate the outcomes of segmental femoral defects treated with monolateral external fixation using t...

OBJECTIVES To compare cleft lip and palate patients' satisfaction with aesthetics and functional parameters after conventional advancement of the maxilla or by the use of distraction osteogenesis. MATERIAL AND METHODS Case series observational study. Group of distraction osteogenesis (DO) consisted of 15 patients treated with distraction osteogenesis while group conventional (CONV) included 1...

OBJECTIVE To determine the effectiveness of distraction osteogenesis of the mandible for relief of airway obstruction in neurologically impaired children. DESIGN Prospective pilot study. SETTING Tertiary care children's hospital. PATIENTS Five children with upper airway obstruction secondary to hypotonia were identified by airway endoscopy, pulse oximetry, and polysomnography. Four childr...

COPYRIGHT © 2015 BY THE JOURNAL OF BONE AND JOINT SURGERY, INCORPORATED » Distraction osteogenesis, utilized for reconstruction of skeletal deformities and bone defects, encompasses three phases of repair that are distinct from those of fracture-healing: latency, distraction, and consolidation. During distraction, osteogenic potential is maintained because of a number of molecular, cellular, an...

Distraction osteogenesis is a biologic process of new bone formation between the surfaces of bone segments that are gradually separated by incremental traction. The process is initiated when distraction forces place tension on the callus between the bone segments, and continues as long as these tissues are stretched. This tension stimulates new bone formation parallel to the vector of distraction.

Objectives. The aim of the study was to investigate the results of patients with isolated length discrepancy between ulna and radius who underwent distraction osteogenesis with unilateral external fixator. Material and Methods. A patient with ulna shortening due to multiple enchondromatosis, a patient with ulna shortening due to ulnar club hand, and a patient with radial shortening due to radia...

This study aimed to evaluate the histological, histomorphometric and radiographic features of the bone repair in ovariectomized rats submitted to mandibular distraction osteogenesis. Thirty female Wistar rats were equally divided in ovariectomy and control group and submitted to mandibular distraction osteogenesis. After 7, 14 and 28 days the animals were sacrificed and mandibles were removed a...

Maxillary distraction osteogenesis is an alternative treatment of cleft patients with severe maxillary hypoplasia. The aim of this paper is to present the combined surgical/orthodontic treatment of a cleft lip and palate patient and to evaluate the maxillary distraction procedure and the distraction vector in high Le Fort I osteotomy.

this case report presents a combination of surgical and prosthetic solutions applied to a case of oral implant rehabilitation in post-oncologic reconstructed mandible. bone resection due to surgical treatment of large mandibular neoplasm can cause long-span defects. currently, mandibular fibula free flap graft is widely considered as a reliable technique for restoring this kind of defect. it re...

Since its introduction in the medical literature in 1992 by McCarthy, distraction osteogenesis of the craniofacial skeleton has become a standard surgical therapy. The present report attempts to trace the development of craniofacial distraction from the perspective of one of the early proponents of the technique. Although the earliest application of distraction was in children with severe unila...
