Following a laboratory rat study where iliac crest was removed, the femoral vessels were placed as a pedicle through the centre of the graft which was wrapped in silastic sheeting and transplanted to the subcutaneous abdominal wall, which showed in all cases bone revascularisation and viability within three weeks. A human study followed in two patients with chronic complex scaphoid non unions where iliac crest was placed in the anterior interosseous pedicle in the proximal forearm. The pedicle was ligated proximally. Four months later, the graft was dissected on its pedicle distally to the scaphoid. In both cases, the scaphoid united and in both cases the bone was viable at biopsy. Rather than this tedious two stage procedure, Russe and Fisk grafts are routinely pedicled with the superficial radial vessels flowing retrograde at scaphoid bone grafting. At the same time of our rat study, Zaidemberg published his dorso-radial radius vascularised pedicled bone graft on the “irrigating artery”. The details were scant as they were at the oral presentation three years later. The irrigating artery was subsequently beautifully demonstrated in Zancolli’s Atlas of Hand Surgery and this and other dorsal pedicled bone grafts of the radius have been well described by Bishop and colleagues at the Mayo Clinic. The technique of 1-2 SRA (Zaidemberg) pedicled bone grafting is described in detail together with the indications for prefabrication and vascularised pedicled bone grafting and the necessary pre operative imaging information to plan and select the correct procedure.
