Chronic scaphoid fracture nonunion continues to present a significant challenge to the treating orthopedic surgeon. Internal fixation with threaded compression screws leads to high union rates, and is currently the gold standard, but there are certainly circumstances where a scaphoid screw does not provide the stability necessary for nonunion repair. Results using a volar buttress plate have been promising, but have not been described in conjunction with the use of vascularized bone graft. Vascularized bone grafts have been shown to be highly effective in achieving rapid and reproducible rates of union. We describe a novel combination of a vascularized volar distal radius wedge autograft pedicled on the volar carpal artery and volar buttress plating for salvage treatment of chronic scaphoid nonunion.
慢性舟骨骨折不愈合仍然给骨科治疗医生带来重大挑战。使用带螺纹加压螺钉进行内固定可实现较高的愈合率,目前是金标准,但在某些情况下,舟骨螺钉无法提供骨折不愈合修复所需的稳定性。使用掌侧支撑钢板的效果令人期待,但尚未有与带血管蒂骨移植联合使用的相关描述。带血管蒂骨移植已被证明在实现快速且可重复的愈合率方面非常有效。我们描述了一种新型联合治疗方法,即采用以掌侧腕动脉为蒂的带血管蒂桡骨远端掌侧楔形自体骨移植与掌侧支撑钢板固定,用于慢性舟骨骨折不愈合的挽救治疗。
