title: Vascular basis of free transfer of proximal epiphysis and diaphysis of fibula: an anatomical study.
abstract: BACKGROUND
  Transfer of proximal epiphysis and diaphysis of fibula is a treatment of bony defects in children. Although there are few reports of this procedure, different arteries or combination of arteries have been used as supplying pedicle and the reported success rates are different. This is an anatomical study to clarify the vascular anatomy of this region.
  
  
  METHODS
  A total of 16 fresh cadavers were enrolled. An incision was made in the popliteal fossa to find the popliteal artery, which was dissected distally and the lateral inferior genicular artery, anterior tibial artery, tibioperoneal trunk and its bifurcation were located. In eight subjects popliteal artery was cannulated above the level of femoral condyles and injected by latex. In the next eight cases the same material was injected in the anterior tibial artery. The next steps of dissection were done by 4.3-loupe magnification. Lateral inferior genicular artery was dissected from its origin to the fibular head and branches of anterior tibial artery were also dissected. In three specimens, the fibula and its supplying arteries were removed after dissection and put in diluted hydrochloric acid to be opened for studying the medullary vasculature.
  
  
  RESULTS
  This study confirms the existence of not only periosteal but also intramedullary anastomosis between artery of the neck and peroneal artery. Artery of the neck was usually a branch of anterior tibial artery and in 24% of the subjects a branch of popliteal artery. In the latter condition the pedicle would be too short to permit the surgeon to do this surgery. Therefore preoperative angiography is mandatory to identify the origin of the artery of the neck.
  
  
  CONCLUSIONS
  According to these dissections, a classification system of arterial supply of proximal fibular epiphysis is introduced in this article.
