The Taylor Spatial Frame (TSF) is a circular external fixator used to treat complex fractures and skeletal deformities. The device consists of 2 rings attached to bone by wires or half pins, connected by universal hinge joints to 6 independent telescopic struts, creating a hexapod. The output piece is defined as the movable ring, which has 6 degree of freedom relative to the other ring, which is the base. With 6 degree of freedom, the movable platform is capable of moving in 3 linear directions and 3 angular directions singularly or in any combination. These hexapod devices require complex mathematical software programs to accurately control the output piece. In the case of the TSF, the deformity and positional frame parameters can be indentified on postoperative radiographs. They are then input into internet-based software to calculate strut adjustments required to achieve deformity correction. When treating fractures with the TSF, the rings can be connected using FastFx struts. These struts can be locked in position or left in a sliding mode (unlocked) allowing manual manipulation of the frame to acutely correct the position of the fracture fragments. This reduction is rarely perfect however and often requires further postoperative frame adjustments using software calculations. We describe an intra-operative method for accurately adjusting the frame in its locked mode without the need for software input.
泰勒空间框架（TSF）是一种用于治疗复杂骨折和骨骼畸形的环形外固定器。该装置由 2 个环通过线或半针固定在骨头上，通过万向铰链关节与 6 个独立的伸缩支柱连接，形成六足架。输出件定义为可动环，它相对于另一个环（即底座）具有 6 个自由度。有了 6 个自由度，可动平台可以单独或任意组合在 3 个线性方向和 3 个角方向上移动。这些六足架装置需要复杂的数学软件程序来准确控制输出件。在 TSF 的情况下，可以在术后 X 光片上识别出畸形和位置框架参数。然后将其输入基于互联网的软件中，以计算出实现畸形矫正所需的支柱调整。在使用 TSF 治疗骨折时，可以使用 FastFx 支柱连接环。这些支柱可以锁定在位置或保持滑动模式（未锁定），允许手动操作框架以急性矫正骨折碎片的位置。然而，这种复位很少是完美的，通常需要使用软件计算进一步进行术后框架调整。我们描述了一种在锁定模式下准确调整框架而无需软件输入的术中方法。
