Chapter 7 Surgical technique

Abstract

The trays containing the tibial instruments, templates and trial components and those used with all sizes of femur are shown in Figure 7.1. A numbered list of illustrations of all the instruments, trial components and templates can be found at the end of this chapter. When a component or instrument is mentioned first in the following text, its number will be printed with square brackets. The five sizes of femoral component have different spherical radii of curvature. For each femoral size, there is a matching set of men iscal bearings in seven thicknesses, from 3 mm to 9 mm. There is a separate tray of instruments for each femoral size. The trays, one of which is shown in Figure 7.2, contain colour coded instruments and trial components specifically for use with one size of femoral component. They must not be mixed up so it is safer just to open one size.
