ABSTRACT
Total hip replacement arthroplasty is one of the most successful
orthopaedic operations performed and the longevity of the implants
depends on accurate component placement. Accurate component
alignment is associated with reduced mechanical wear, dislocation
and revision surgery. Traditionally, accurate component alignment
relies on the surgeon using jigs and referencing these from
anatomical landmarks. However, this leads to a wide variability
in component position. Computer navigation systems aim to
optimise component placement and optimise longevity. This chapter
will describe the different types of computer navigation systems
available and their use in total hip arthroplasty and hip resurfacing.
This chapter will also highlight the limitations to navigation that
have prevented a more widespread uptake.
