Fig. 1. Schematic of one-stage bone-transport procedure (yellow – bone, red – periosteum). A portion of diaphyseal bone is denuded of periosteum, osteotomized, and transported over an intramedullary nail to the site of the 2.54-cm critical-sized defect, where it is docked to the distal femur. The periosteal sheath is left in situ to surround the new defect site, leading to full infilling of the...

Restoration of bone defects in the oral cavity is one of the major challenges for dental surgeon. A common example is handling of bone defect after simple tooth extraction for ridge preservation. Often delivering prosthodontic and implant treatments face difficulties during oral rehabilitations in bone defect site. Bone defect site needs to be restored in such a way to support further treatment...

This study addresses the hypothesis that callus formation, patterning, and mineralisation are impaired during the early phase of critical sized bone defect healing, and may relate to inter-fragmentary tissue strains within the bone defect area. Twenty four 12 week old Sprague Dawley rats were used for this study. They were divided into two groups defined by the femur bone defect size: (i) 1 mm ...

The synthetic material Nanobone(®) (hydroxyapatite nanocrystallines embedded in a porous silica gel matrix) was examined in vivo using a standardized bone defect model in the ovine tibial metaphysis. A standardized 6 × 12 × 24-mm bone defect was created below the articular surface of the medial tibia condyles on both hind legs of 18 adult sheep. The defect on the right side was filled with Nano...

OBJECTIVE Develop a model that allowed the study of bone regeneration in infection conditions. METHOD A 15 mm defect was surgically created in the rabbit ulna and inoculated with 5x10(8) colony-forming units (CFU) of S. aureus. Surgical debridement was performed two weeks after and systemic gentamicin was administered for four weeks. Animals were followed up to 12 weeks to evaluate infection ...

In a previous experiment, it was demonstrated that a wide marginal defect around an implant can heal with a high degree of osseointegration. The present experiment was performed to evaluate the degree and quality of de novo bone formation and osseointegration in marginal defects adjacent to submerged titanium implants. All mandibular premolars and 1st molars were extracted in four Labrador dogs...

It is well known that the periosteum is capable of bone formation. In the present study, the value of the vascularized periosteal graft in healing the long-bone defect filled with the allogenous bone graft was studied. The aim of the study was to verify the efficiency of the rotational vascularized periosteal graft as a optional surgical method as well as to prove its advantages in comparison w...
