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.

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 ...

Vascularized Bone Grafts to the Upper Extremities

Plastic and Reconstructive Surgery, 1998
From 1979 to 1995 in our clinic, vascularized bone grafting was performed in 29 patients with large bone defects, established nonunion, congenital pseudoarthrosis, or avascular necrosis in the upper extremity. Four patients had traumatic bone defects, six had posttraumatic nonunions, two had congenital pseudoarthroses, five had amputations, nine had ...

THE EARLY VASCULARIZATION OF ONLAY BONE GRAFTS

Plastic and Reconstructive Surgery, 1976
On 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

Vascularized Bone Graft for Scaphoid Nonunion

Techniques in Hand and Upper Extremity Surgery, 2003
The management of recalcitrant nonunion of the scaphoid can be frustrating. Recent understanding of the vascular anatomy of the distal radius has helped in the management of these problems. Vascularized bone grafting for scaphoid nonunion has improved the union rates.

Vascularized Bone Grafts for Scaphoid Nonunions

The Journal of Hand Surgery, 2012
Scaphoid fractures that fail to unite are at risk of developing avascular necrosis and progressive structural collapse, thereby complicating attempts at revision surgical treatment. Vascularized bone grafts have demonstrated utility in promoting consolidation in the treatment of scaphoid nonunions complicated by avascular necrosis.

Thrombosed Vascularized Bone Graft: Viability Compared with a Conventional Bone Graft

Journal of Reconstructive Microsurgery, 1987
Previous 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, 2004
Scaphoid 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.

Vascularized Bone Grafts

2019
With the introduction of microsurgery, even patients with severe defects due to trauma, tumor, infections, or deformities can be treated successfully with the concept of dental rehabilitation by using implants. In the past, concepts including obturator prosthesis or reconstruction plates limited the possibilities of full dental rehabilitation including
