Thrombosed Vascularized Bone Graft: Viability Compared with a Conventional Bone Graft
Journal of Reconstructive Microsurgery, 1987Previous reports in the literature have suggested that the viability of a thrombosed vascularized bone transfer is similar to that of a conventional bone graft. Our clinical impression, however, has been that this is not the case. The viability of thrombosed vascularized bone grafts was compared with that of conventional nonvascularized grafts in a ...

Vascularized Bone Graft for Scaphoid Nonunions
Techniques in Hand & Upper Extremity Surgery, 2004Scaphoid fracture nonunion remains a challenging problem that may persist despite traditional methods of bone grafting and internal fixation. The alteration of wrist mechanics created by nonunion as well as the development of avascular necrosis leads to degenerative change of the radiocarpal joint accompanied by loss of motion and pain.

Supplemental Graft Fixation for Distal Radius Vascularized Bone Graft
The Journal of Hand Surgery, 2012Vascularized bone grafts from the distal radius have been used successfully for the treatment of scaphoid nonunions. Typically, the harvested graft is secured into the scaphoid with a press-fit technique. This type of fixation may lead to graft extrusion in the early postoperative period, and thus to treatment failure.

AUTOGENOUS BONE GRAFTS: NONVASCULAR AND VASCULAR
Orthopedics, 1992ABSTRACT Nonvascularized autogenous bone grafts have been used for at least 150 years. Vascularized bone grafts were first done only 17 years ago. We now know that bone grafts act through osteoconductive and osteoinductive mechanisms to produce new bone.

Treatment of scaphoid nonunion: Pedicled vascularized bone graft vs. traditional bone graft
Journal of Huazhong University of Science and Technology [Medical Sciences], 2013The clinical results of the application of pedicled vascularized bone graft (VBG) from Lister's tubercle vs. traditional bone graft (TBG) were evaluated and compared. Thirteen cases of symptomatic scaphoid nonunion were treated between January 2011 and December 2012, including 7 cases subject to VBG and the rest 6 cases to TBG, respectively.

Vascularized Bone Grafts for Maxillofacial Reconstruction
Clinics in Plastic Surgery, 1989Vascularized bone transfers are the ideal bone graft since they provide their own blood supply and all necessary osteoinductive, osteoconductive, and osteoprogenitor elements. These attributes allow them to be used in compromised recipient sites. When used as onlay grafts to augment skeletal contour they provide the best opportunity to maintain volume.

Prefabrication of Vascularized Bone Graft Using Guided Bone Regeneration
Tissue Engineering, 2004This article describes the prefabrication of a vascularized bone graft composed of autologous particulate cancellous bone and marrow (PCBM), a vessel bundle, and a biodegradable membrane. The PCBM was placed around the saphenous vessel bundle of rats and rolled with a biodegradable membrane of L-lactide-epsilon-caprolactone copolymer to prepare the ...

THE EARLY VASCULARIZATION OF ONLAY BONE GRAFTS
Plastic and Reconstructive Surgery, 1976On the basis of this work, several conclusions may be drawn. (1) Autogenous iliac crest onlay bone grafts in the rat vascularize as early as 3 days. (2) The presence or absence of periosteum transferred with the graft has no significant effect on the rate of vascularization. Neither was a difference noted when grafts were placed above or below the host

When the blood supply is cut off from a piece of bone, it becomes non-viable, and the osteogenic cells responsible for bone union will not survive long. In animal experiments, the osteoblasts might survive for as long as 25 h [1], but in human bone, it is still uncertain whether the same applies.

Bone Remodeling of Vascularized Bone Graft
1990The purpose of the present research was to observe roentgenographically the remodeling of vascularized bone graft and to study the difference between the remodeling of vascularized bone graft and that of conventional free bone graft.
