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.
Claims20
A humeral fixation plate, comprising:
- a medial side configured to engage a lateral side of a humerus when the fixation plate is applied to the humerus;
- a lateral side opposite the medial side configured to face away from the humerus when the fixation plate is applied to the humerus;
- a distal portion configured to engage a portion of the humerus distal to a fracture of the humerus;
- a proximal portion configured to engage a head portion of the humerus proximal to the fracture of the humerus;
- a slot defined by the distal portion of the humeral fixation plate, the slot extending from the lateral side to the medial side and along a longitudinal axis of the humeral fixation plate from a first end toward a second end, the second end disposed proximal to the first end,
- wherein the slot includes a plurality of discrete position sites disposed along the longitudinal axis between the first end and the second end, the discrete position sites spaced apart from one another along the longitudinal axis.
A tuberosity fracture plate, comprising:
- a tuberosity end having a first portion configured to overlay a first tuberosity and a second portion opposite the first portion;
- a distal portion coupled with and extending away from the tuberosity portion;
- a first anchor hole defined by the tuberosity end;
- a second anchor hole defined by the distal portion;
- and
- a bend zone disposed between the first anchor hole and the second anchor hole;
- wherein the bend zone is configured to bend upon application of a load to the tuberosity end, to the distal portion, or to both the tuberosity end and the distal portion.
