The purpose of this study was to demonstrate the peri- and intraosseous vascular supply of the proximal ulna.
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 studied.
Proximal 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 branches.
The peri- and intraosseous vascularization of the proximal ulna was shown. A transitional zone of the intraosseous vascularization of the proximal ulna was detected.
本研究的目的是展示尺骨近端的骨膜内和骨内血管供应情况。
对11个新鲜的人体尸体肘部依次进行塑化处理，先进行动脉注射，然后对整个肘部进行整块和二次切片塑化。通过这种技术，我们获得了完全透明的尸体切片，在其中可以研究骨膜内和骨内的血管结构。
尺骨近端的血管化归因于一个动脉网络：尺侧上副动脉和尺侧下副动脉，以及从近端向上攀爬至鹰嘴的肱深动脉。一条前动脉和一条尺侧返后动脉向尺骨内侧远端攀升，一条骨间返动脉负责尺骨近端的外侧和后外侧部分。骨内血管化归因于直接从尺侧返后动脉穿出的分支以及鹰嘴尖处的血管丛。此外，我们还看到一条主要的远端骨穿透分支来自返后动脉，在骨内向上攀爬，未与近端穿透分支汇合。
