Abstract
Eleven fresh human cadaveric elbows were sequentially plastinated beginning with arterial injection followed by block and secondary slice plastination of the whole elbow With this technique we obtained completely transparent cadaveric slices in which the peri and intraosseous vascular architecture could be studiedProximal ulna vascularization is due to an arterial network a superior and inferior collateral ulnar artery and the profunda brachial artery climbing to the olecranon from proximal An anterior artery and a posterior recurrent artery climb up distally to the medial parts of the ulna and an interosseous recurrent artery is responsible for the lateral and posterolateral proximal part of the ulna The intraosseous vascularization is due to directly penetrating branches out of the posterior recurrent ulnar artery and a vascular plexus at the olecranon tip In addition we saw a major distal bone penetration branch coming from the recurrent posterior artery climbing intraosseously without junction to the proximal penetrating branchesThis study was not supported by any company The first author got fundings from Orthofix Orthofix™ Bussolengo Italy for different other research projects All results were obtained independently and without any critical comments from the company The authors have not obtained any benefits for this study Commercial principles did not alter or interfere with the results of this study
