Experimental physial distraction was carried out in the distal part of the femur in 45 two-month old lambs in order to study the basic mechanisms of lengthening as well as the viability of the growth cartilage after using this method. The animals were divided into three groups (A, B and C), and each group into three subgroups (1, 2 and 3) according to the rate of distraction used (2 mm/day, 1 m...

The paper describes the technique and application of a tricortical bone graft harvesting from lateral malleolus. Graft does not interfere with continuity fibula. Due to its structure, is equivalent similarly structured taken iliac crest. used in osteotomies arthrodesis within foot ankle joint, which require strong piece as wedge. author typically uses this type for osteotomy anterior part calca...

Introduction: Since crown lengthening surgery could be accompanied by stress, pain and discomfort, knowledge about its predisposing factors could reduce the demands for such surgery.The aim of this study was to identify the most important indications of crown lengthening surgery in order to present new ideas to clinicians on how to reduce the need for this surgery. Methods: This cross-sectio...

OBJECTIVE Distraction osteogenesis (DO) is a surgical procedure used to generate large volumes of new bone for limb lengthening. MATERIALS AND METHODS In this animal experimental study, a 30% lengthening of the left tibia (mean distraction distance: 60.8 mm) was performed in ten adult male dogs by callus distraction after osteotomy and application of an Ilizarov fixator. Distraction was start...
