Abstract:
Cement spacer as a reconstruction technique in proximal humerus resections in malignant and benign conditions is well established. Functional outcome of any reconstruction is decided by how well soft tissue reconstruction has been carried out. The cement spacer technique allows soft tissue reattachment at any site required as compared to prosthetic reconstruction, but such reattachment sites have to be decided before setting of the cement. Here we describe a technique in which a prolene mesh is used as a mould for the cement. The outer prolene mesh gives the surgeon the opportunity to anchor soft tissues during closure at any area desired. The mesh creates a porous surface over the stem which will aid in better healing by fibrosis for the muscle as compared to healing over smooth cement. Mesh fibrosis is another added point of stability at the bone-construct junction. Post-operative shoulder range of motion was easier to achieve in such patients.
摘要:
骨水泥垫片作为恶性和良性条件下肱骨近端切除术中的重建技术已经确立。任何重建的功能结果取决于软组织重建的执行程度。与假体重建相比,水泥垫片技术允许在任何需要的部位重新附着软组织。但是这种重新附着的地点必须在水泥凝固之前决定。在这里,我们描述了一种技术,其中使用丙烯网作为水泥的模具。外部普罗林网状物给予外科医生在闭合期间将软组织锚定在所需的任何区域的机会。网状物在杆上产生多孔表面,与在光滑水泥上愈合相比,这将有助于通过肌肉纤维化更好地愈合。网状纤维化是骨-构建体连接处的另一个增加的稳定性点。此类患者的术后肩部活动范围更容易实现。
