Biomechanical strength of non-vascularised and vascularised diaphyseal bone transplants. An experimental study.

چکیده
We studied the healing and torsional strength of non-vascularised (28) and vascularised (28) sections of tibial diaphyses in 56 cats. Both types of graft achieved fracture union in the same period of time, and at 12 and 16 weeks the non-vascularised grafts were as strong as the vascularised grafts.

Healing of Non-vascularised Diaphyseal Bone Transplants
Four different experiments were performed to study the healing of a large, non-vascularised, diaphyseal, bone segment in adult cats. In the first experiment, a 4 cm segment of tibia with its periosteum was excised and replaced in its bed. The other experiments were similar, except that in the second, the periosteum of the segment was removed, in the third its medullary canal was blocked with a ...
متن کاملNon-vascularised fibula grafts for reconstruction of segmental and hemicortical bone defects following meta- /diaphyseal tumour resection at the extremities
BACKGROUND The reconstruction of meta-/diaphyseal bone defects following bone tumour resection is challenging, and biological treatment options should be applied whenever possible, especially in benign lesions and early stage sarcomas. We aimed to evaluate the results of segmental (SR) and hemicortical reconstructions (HR) at the extremities using non-vascularised fibula grafts. METHODS We re...
متن کاملFunctional long-term results after the harvest of vascularised iliac bone grafts bicortically with the anterior superior iliac spine included.
The aim of this study was to evaluate the postoperative morbidity at the donor site and the long-term outcome after the harvest of bicortical iliac bone grafts, including the iliac crest and the anterior superior iliac spine (ASIS), by using a confirmed score. We retrospectively examined 54 consecutive patients who had had vascularised iliac bone grafts harvested to reconstruct different parts ...
متن کاملAn Experimental Study Using Laser Doppler Flowmetry
We used laser Doppler flowmetry (LDF) to measure flux in cortical bone fragments as a method of determining their vascular status and viability. In an experimental tibial osteotomy measurements of flux were made from specific cortical sites both before and after osteotomy. Flux levels fell rapidly in non-vascularised fragments and remained significantly reduced throughout the experiment. By con...
متن کاملReconstruction of the distal radius with non-vascularised fibular graft after resection of giant cell tumour of bone.
PURPOSE To evaluate outcomes of wide resection and reconstruction of the distal radius with non-vascularised autogenous fibular grafts for giant cell tumour (GCT) of bone. METHODS Medical records of 7 men and 5 women aged 22 to 47 (mean, 31) years who underwent wide resection of the distal radius and reconstruction with non-vascularised autogenous fibular grafts for GCT of bone were reviewed....
