Focal dome osteotomy (FDO) is a cylindrically shaped osteotomy, with corresponding bone cuts rotating around the central axis of the deformity. Thus, complete correction can be achieved without secondary translation. FDO provides high adjustability of the bone ends, optimal bone contact, and high primary stability. As with straight cut closing, neutral, and opening-wedge osteotomies, FDO allows closing, neutral, and opening corrections. Opening FDO allows preservation of bone contact, whereas closing FDO does not require removal of bone stock. The osteotomy can be modified to tighten the medial collateral ligament. A FDO below the tuberosity does not compromise patellofemoral function and reduces the risk of intra-articular fractures. Sufficient bone stock of the proximal tibial or distal femoral fragment allows intramedullary stabilization. FDO is of high value in the treatment of sagittal plane and frontal plane corrections of the knee even in severe deformities.
局限性穹顶截骨术(FDO)是一种圆柱形截骨术,相应的骨切口围绕畸形的中心轴旋转。因此,无需二次平移即可实现完全矫正。FDO提供了骨端的高可调节性、最佳的骨接触和高初始稳定性。与直切闭合、中立和开口楔形截骨术一样,FDO允许进行闭合、中立和开口矫正。开口FDO可保留骨接触,而闭合FDO则无需去除骨块。截骨术可进行改良以收紧内侧副韧带。结节下方的FDO不会损害髌股关节功能,并降低关节内骨折的风险。胫骨近端或股骨远端骨块有足够的骨量允许进行髓内固定。即使在严重畸形的情况下,FDO在膝关节矢状面和额状面矫正治疗中也具有很高的价值。
