Vascularized graft donor locations include the distal radius, medial femoral condyle, metacarpal, and ulna.
The 1,2 intercompartmental supraretinacular artery (1,2 ICSRA) pedicle graft is a commonly used vascularized graft. It originates from the radial artery 5 cm proximal to the radiocarpal joint.
Consequently, local vascularized grafts
of fibularis brevis cannot depend adequately on these perforating branches since rotation of the flaps may jeopardize their blood supply.

in augmenting tibial intercalary allograft constructs?," Clinical Orthopaedics and Related Research, vol.
The advantage of vascularized grafts
was clearly demonstrated based on animal studies and in clinical trials [4, 27, 39].
An experimental study on dogs showed conclusively the superiority of vascularized grafts
over nonvascularized grafts or other foreign materials in preventing scar formation .
Vascularization of this system plays an important role, considering that the comparison of vascularized and non-vascularized grafts in an animal model revealed that integration to the adjacent bone was faster in the vascularized grafts
, although all of them achieved adequate bone formation in the 20 and 30-week follow-ups (Evans et al., 1991).
