A new vascularized bone graft for scaphoid nonunion
The Journal of Hand Surgery, 1991Nonunion and avascular necrosis after scaphoid fractures continue to be problem sequelae because of unrecognized injuries, inadequate immobilization techniques, or insufficient treatment time. Screw fixation and inlay bone grafting techniques remain the options of choice, with successful union reported in approximately 90% of patients.

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.

Fracture Through United Vascularized Bone Grafts
Journal of Reconstructive Microsurgery, 1993The secondary fracture rate in 53 patients undergoing vascularized bone transfer for long-bone reconstruction, with a follow-up period of at least 2 years, is evaluated in this report. Twelve fractures occurred in 10 patients. Characteristics of the fractures were: (1) most occurred at the tibia recipient site; (2) most occurred through the transferred

Fixation of the Vascularized Bone Graft in Mandibular Reconstruction
Plastic and Reconstructive Surgery, 1993One hundred and forty vascularized bone grafts were used for mandibular reconstruction in 135 patients. Most followed surgical ablation of squamous carcinoma recurring (or persisting) after irradiation. This paper analyzes the fixation techniques and their effects on bony union. Of 140 vascularized bone grafts, 132 survived and were reviewed.

A VASCULARIZED BONE GRAFT FOR REPAIR OF SCAPHOID NONUNION
Hand Clinics, 2001The majority of scaphoid fractures respond to casting, splinting, or open reduction and internal fixation. In patients who fail to heal a scaphoid fracture, several factors may contribute, including delay in treatment, fracture displacement, proximal third location, avascular necrosis, and associated carpal instability.

THE FREE VASCULARIZED BONE GRAFT
Plastic and Reconstructive Surgery, 1975For the common problem of lower limb injury with extensive. Loss of skin and bone, a new method of free vascularized bone grafting has been used and integrated with an appropriate soft tissue flap repair. The technique was developed to salvage two legs which would otherwise have been amputated. The preliminary result in Case 2 is encouraging. This case

Free vascularized bone graft in the treatment of pseudarthrosis
International Orthopaedics, 1982Free vascularized bone transplantation was performed for the treatment of pseudarthrosis in seven patients, in all of whom the conventional methods had failed; by transplantation of vascularized fibular or iliac bone graft useful fusion was achieved.

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.

[Vascularized bone graft in carpal bone reconstruction].
Annales de chirurgie plastique et esthetique, 2005We report our experience of vascularized bone graft harvested from the volar aspect of the distal radius for carpal bone reconstruction. Thirty cadaveric dissections showed in all cases the volar carpal artery which born from the radial artery. Between 1994 to 2001, we treated 87 scaphoid non-unions with an average follow-up of 41 months (range 6 to 65

Fate of Vascularized Bone Grafts
1989Advances in the field of microsurgery over the past decade have made it possible to provide a continuing circulation to bone grafts used in the reconstruction of extremities with massive segmental bone loss following trauma or secondary to tumor resection.
