Abstract: An improved tibial cutting jig is provided for use in obtaining accurate tibial resection in the course of a total knee prosthesis implantation procedure. The tibial cutting jig includes a base for sliding reception onto an intramedullary alignment rod preinstalled generally along the longitudinal axis of the tibia. The base includes laterally extending outriggers carrying removable measurement keys of selected size for spacing the base above the tibial plateau by a selected dimension. An anterior saw guide depends from the base and is thus positioned relative to the tibial plateau in accordance with the sizes of the measurement keys.
Abstract translation: 提供了一种改进的胫骨切割夹具，用于在全膝关节假体植入术过程中获得准确的胫骨切除。 胫骨切割夹具包括用于滑动接收到大致沿着胫骨的纵向轴线预先安装的髓内对准杆的基部。 基部包括横向延伸的支腿，其携带选定尺寸的可拆卸测量键，用于将胫骨平台上方的基座间隔一定尺寸。 前锯导向件从基座取向，并且因此根据测量键的尺寸相对于胫骨平台定位。
