Abstract
A surgical instrument is described which comprises an alignment guide having a first part including a distal end and a second part having a proximal end. The first part is attached to the second part by a pivot mechanism so that the first part can be tilted relative to the second part. A brace is attached toward the proximal end of the alignment guide for attaching the instrument to a limb of a patient. A component is attached toward the distal end of the alignment guide. The pivot mechanism is configured so that tilting the first part does not substantially change the separation between the component and the brace.

A surgical instrument for aligning a component relative to a bone, the bone contained within a limb, the instrument comprising:
- a brace for releasable attachment to the limb;
- a lower part attached to the brace and extending from the brace along a longitudinal axis;
- a housing slidably attached to the lower part along the longitudinal axis, the housing comprising a curved member that extends away from the longitudinal axis;
- and
- a second part that is slidable relative to the lower part along the longitudinal axis and is slidably attached to the curved member, the second part comprising a cylindrical portion disposed at least partially about the lower part and a sleeve disposed at least partially about the curved member, the sleeve being pivotable from a first position, whereat the cylindrical portion is aligned with the longitudinal axis and a second position, whereat the cylindrical portion is not aligned with the longitudinal axis.
