Delayed distraction in bone lengthening. Improved healing in lambs.
We compared delayed distraction (DD) with immediate distraction (ID) in bone-lengthening. Open femoral diaphyseal osteotomy was performed on 24 three-month-old lambs, and external distractor fixators were applied. In the ID group (n 12), distraction commenced on the first postoperative day; in the DD group (n 12), distraction was delayed until the tenth day after surgery. In all the animals, th...
متن کاملDenervation impairs bone regeneration during distraction osteogenesis in rabbit tibia lengthening
BACKGROUND AND PURPOSES The nervous system plays an important role in bone metabolism. However, the effect of denervation on bone formation during distraction osteogenesis (DO) remains unclear. We studied neural influence on bone regeneration during DO in a rabbit model. METHODS 24 New Zealand male white rabbits underwent left tibial osteodistraction. Before distraction, the animals were rand...
متن کاملFactors influencing bone regenerate healing in distraction osteogenesis.
BACKGROUND The dynamics and effectiveness of new bone formation in the Ilizarov method varies according to different factors. Some of them may result in substantial prolongation of treatment time. The lengthening index (LI), defined as the number of months in a frame necessary to achieve 1 cm lengthening, is the main indicator of bone healing potential. The purpose of the study was to assess th...
متن کاملMolecular signaling in bone fracture healing and distraction osteogenesis.
The process of fracture healing has been described in detail in many histological studies. Recent work has focused on the mechanisms by which growth and differentiation factors regulate the fracture healing process. Rapid progress in skeletal cellular and molecular biology has led to the identification of many signaling molecules associated with the formation of skeletal tissues, including memb...
متن کاملHumeral lengthening and deformity correction in Ollier's disease: distraction osteogenesis with a multiaxial correction frame.
A case of Ollier's disease with deformity and shortening of the humerus is presented. Lengthening of 9 cm and deformity correction of 50 degrees were accomplished with excellent functional and cosmetic results. Unique features of this case were the use of a multiaxial correction monolateral frame and the formation of normal bone within the region of diseased Ollier's bone.
