Trial reduction
With the broach in place, a trial head is fitted to its tapered cone (Fig. 19). The hip is reduced by extension, traction, lateral rotation and abduction (Fig. 20).

The following points can then be verified :

• Leg length can be checked using the short, standard or long necked trial heads with a diameter matching that of the insert.
• The stability of the hip joint can be checked.
