VASCULARIZED BONE GRAFTS

Orthopedics, 1994
ABSTRACT Free vascularized bone grafts allow living bone tissue to be transplanted to replace a bone defect. The use of vascularized bone grafts requires microvascular dissection and attachment to a recipient site artery and vein, whereas rotational or pedicle grafts are moved, while still attached to their blood supply, to a new site ...

Bone graft viability in vascularized bone graft transfer

The British Journal of Radiology, 1982
Five cases of vascularized bone grafts were analysed to determine viability using angiography 6-8 weeks after surgery and radionuclide bone imaging 8-10 weeks after surgery. The results were comparable to each other and to clinical progress. Both examinations were considered useful in assessment of these cases.

Fixation of vascularized bone grafts

Journal of Cranio-Maxillofacial Surgery, 1993
In 24 patients, fixation of isolated or combined bone grafts has been performed exclusively with miniplates. Other than the lateral displacement of one osteomyocutaneous iliac crest graft, no complication occurred with regard to the fixation method chosen.

Free vascularized bone graft

The Journal of Foot and Ankle Surgery, 1996
This article reviews free vascularized bone grafts. Indications for use, advantages, and disadvantages of free vascularized versus nonvascularized bone grafts as well as applications to foot and ankle surgery are presented. A single case report is also presented.

Biology of Vascularized Bone Grafts

Orthopedic Clinics of North America, 1987
Vascularized canine fibular autografts demonstrated improved biologic and mechanical characteristics 3 months after surgery when compared with nonvascularized controls. The vascularized proximal fibula maintained its overall architecture without bony collapse or significant bone turnover. The strength and stiffness of these grafts were approximately 40

Experimental Study of Vascularized Bone Grafts: Hypertrophy of the Grafted Bone

Journal of Reconstructive Microsurgery, 2000
The mechanism underlying hypertrophy of experimentally vascularized bone grafts was studied in 15-week-old rats. The segmental ulna was grafted to the tibial defect with an external fixator. In experiment 1, 24 rats were classified into four groups to evaluate conventional (non-vascularized), cuff (periosteum-encased, non-vascularized), and ...

Long Bone Reconstruction with Vascularized Bone Grafts

Orthopedic Clinics of North America, 2007
The vascularized fibula may be used for long bone reconstruction reliably and successfully. Since its description by Taylor, the fibula flap has evolved to solve a myriad of long bone reconstructive dilemmas. The flap is used routinely for non-unions, postoncologic resections, and congenital defects.

Vascularized Tail Bone Grafts in Rats

Plastic and Reconstructive Surgery, 1993
A new experimental model for vascularized corticocancellous bone grafts was established by investigation of vascular anatomy of the tail in 15 adult Fischer 344 rats and determination of the viability of vascularized tail bone grafts into the abdominal wall in 22 7-week-old rats.

Vascularized Bone Grafts in Orthopaedic Surgery

JBJS Reviews, 2017
* Preclinical animal studies have demonstrated that vascularized bone grafts increase blood flow, maintain patent pedicles, provide immediate structural integrity, hypertrophy in response to mechanical stress, and deliver proper environments for healing in challenging situations.* The absolute indications for vascularized ...

Vascularization of cancellous chip bone grafts

American Journal of Veterinary Research, 1985
SUMMARY Fresh autogenous, frozen allogeneic, and commercially prepared xenogeneic cancellous chip bone grafts were placed into plug holes in the tibia and into surgically simulated nonunion defects in the ulna of dogs. The microvascular and correlated histologic reactions were studied at given times up to 12 weeks after the graft implantation.
