High-energy injuries to the hand frequently lead to bone defects as well as soft tissue loss. Early bone grafting of defects is well established in the literature; however, few options are available for autologous corticocancellous grafts. Most frequently cited studies describe the iliac crest or the distal radius donor sites.
In this case report, we describe a new technique of obtaining corticocancellous bone graft from the olecranon.
Complete union of the segmental defect was achieved with this technique.
The olecranon donor site is outside the zone of injury and therefore safe to access, but within the upper extremity, thus avoiding the need for harvest from a distant site such as the iliac crest or the distal femur. Additional benefits of this site are the greater volume of graft that can be harvested compared to the distal radius as well as a more optimal ratio of cancellous to cortical graft available, compared to the iliac crest where the graft may be excessively cortical in nature.
手部高能损伤常导致骨缺损和软组织缺失。文献中对于缺损的早期骨移植已有充分的记载;然而,自体皮质松质骨移植的选择却很少。最常被引用的研究描述了髂嵴或桡骨远端作为供区。
在本病例报告中,我们描述了一种从尺骨鹰嘴获取皮质松质骨移植的新技术。
采用该技术实现了节段性缺损的完全愈合。
尺骨鹰嘴供区位于损伤区域之外,因此易于获取且安全,同时位于上肢,从而避免了从髂嵴或股骨远端等远处获取供骨。该供区的其他优点包括与桡骨远端相比可获取更大体积的移植骨,以及与髂嵴相比可获得更理想的松质骨与皮质骨移植比例,髂嵴获取的移植骨可能皮质成分过多。
