Distraction osteogenesis (DO) is one of the most dramatic in vivo applications of mechanical stimulation as a means of inducing bone regeneration. A simple and reproducible murine model of tibia distraction osteogenesis was developed using a monolateral fixator. Bone formation was assessed histologically over a 35-day time course. The steady state expression of a broad family of angiogenesis-as...

Two experiments were conducted to test competing accounts of the distractionpersuasion relationship, thought disruption and effort justification, and also to show that the relationship is not limited to counterattitudinal communication. Experiment 1 varied distraction and employed two discrepant messages differing in how easy they were to counterargue. In accord with the thought disruption acco...

Background: Motor vehicle crashes (MVC) cause variable injury to the thoracolumbar (TL) region of children secondary rapid deceleration from seatbelts. This mechanism can also predispose a child intraabdominal (IAI), which necessitates early diagnosis limit morbidity and mortality. While maximum extent TL-spine be appreciated shortly after presentation, severity IAI may not until days later. It...

Background: Pain is described as the fifth vital sign, and inadequate pain management is linked to numerous immediate and long-term negative outcomes. Venipuncture is one of the most painful medical procedures in children. Distraction is one of the most effective ways to relieve pain. Reducing patients’ pain is important for all nurses for many reasons. Unnecessary pain can damage the nurse-...

PURPOSE: Although numerous publications have described distraction osteogenesis (DO) for craniosynostosis, methods of reporting quantitative results have been inconsistent. Therefore, the efficacy of anterior DO and posterior DO in regards to volume change is not well established. We report a metric that relates volume change to distraction length and our analysis of ICV change by distraction o...

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.

Both invasive and non-invasive methods of ankle joint distraction for arthroscopic procedures have been described. Challenges prevail in achieving an adequate joint distraction for instrumentation inside the ankle joint especially in patients of large stature. We describe a technique, which safely offers effective joint distraction during ankle arthroscopy without the need for resorting to trac...

Paediatric patients are often subjected to unexpected medical procedures that cause pain such as intravenous (IV) insertions, intramuscular injections and central venous port access. Distraction is a commonly used non-pharmacologic pain management technique. Distraction is a technique that has been used in hospitals to help children to tolerate painful medical procedures. The current study aime...

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.
