Abstract
An anchor trajectory guide and methods of use thereof are provided. The guide includes a body that has a medial side. The medial side can be placed over a lateral side of a fixation plate. The anchor trajectory guide also includes a locator and a plurality of guide apertures. The locator is disposed on or through the medial side of the body. The locator can be mated with the fixation plate. The guide apertures are disposed through the body at positions corresponding to define anchor locations and orientations to provide good purchase adjacent to or in cortical bone around a medial side of a humerus.

A bone anchor trajectory guide, comprising:
- a body including a medial side configured to be placed over a lateral side of a fixation plate;
- a locator on or through the medial side of the body, the locator configured to mate with the fixation plate;
- and
- a plurality of guide apertures through the body at positions corresponding to defined anchor locations of the fixation plate, wherein
- the body includes a first portion that has a constant thickness in the medial-lateral direction between a second portion and a first terminal end of the anchor trajectory guide, and
- in the second portion, the body is gradually thinner in the medial-lateral direction between the first portion and a second terminal end of the anchor trajectory guide, which is opposite to the first terminal end.
