Limb salvage has now replaced amputation as the standard treatment for primary bone tumors and can usually be offered to more than 85% of patients. Recently, a novel approach to limb salvage has been described by Capanna and colleagues whereby a massive bone allograft and intramedullary vascularized fibula are combined to reconstruct large, segmental bone defects. This produces a structurally competent reconstruction with enhanced vascular and osteogenic capabilities and the potential to achieve lower rates of infection, fracture, and nonunion. The Capanna technique has become a well-established means of long bone reconstruction and limb salvage in cases of large bony resection. The operative technique and reported outcomes of the Capanna technique are reviewed, and cases are presented.
保肢治疗现已取代截肢成为原发性骨肿瘤的标准治疗方法，通常可提供给超过 85%的患者。最近，Capanna 及其同事描述了一种新的保肢方法，即使用大块同种异体骨移植和带血管的腓骨重建大段骨缺损。这种方法可构建具有增强的血管生成和成骨能力的结构稳定的重建体，并且有降低感染、骨折和骨不连发生率的潜力。Capanna 技术已成为大型骨切除后长骨重建和保肢的一种成熟手段。本文回顾了 Capanna 技术的手术技术和报告结果，并介绍了相关病例。
