Abstract
A surgical jig for determining an axis extending into the end of a bone (2). The jig comprises a platform (10) arranged to be supported upon a resected surface (4) at an end of a bone (2), first and second clamps (16) and an alignment guide (18). The first and second clamps (16) are coupled to the platform (10) and are arranged to engage first and second portions of a bone lip (6) extending around at least part of the resected surface (4) to secure the platform (10) to the resected surface (4). The alignment guide (18) defines an axis extending into the end of the bone (2), the alignment guide (18) being pivotally coupled to the platform (10). A method of determining an axis extending into the end of a bone (2) using the surgical jig is also disclosed. The method comprises resecting the end of a bone (2) to leave a bone lip (6), coupling the surgical jig to the resected end of the bone (2), and pivoting the alignment guide (18) until the alignment guide (18) coincides with a required axis extending into the end of the bone (2).
