Abstract
An instrument assembly for an orthopedic procedure is disclosed. The instrument assembly can optionally include any one or combination of a reamer and a cut guide assembly. The cut guide assembly can be configured to couple to the reamer. The cut guide assembly can optionally include any one or combination of a clamp, a carriage and a cut block. The clamp can be selectively movable along a shaft of the reamer and lockable thereto. The first arm can project from the reamer. The carriage can be selectively moveable along a longitudinal length of the first arm. The cut block can be coupled to the carriage via one or more magnets.
Claims20
An instrument assembly for an orthopedic procedure, comprising:
- a reamer;
- and
- a cut guide assembly configured to couple to the reamer, the cut guide assembly comprising:
- a clamp selectively movable along a shaft of the reamer and lockable thereto;
- a first arm projecting from the reamer;
- a carriage selectively moveable along a longitudinal length of the first arm;
- and
- a cut block coupled to the carriage via one or more magnets.
An instrument system for an orthopedic procedure comprising:
- a reamer;
- a cut guide assembly configured to couple to the reamer, the cut guide assembly comprising:
- a first arm;
- a clamp configured to be movable along a shaft of the reamer, wherein the clamp includes a leaf spring configured to be positioned within the firm arm and configured to deflect when selectively engaged with the shaft of the reamer to lock the clamp to the shaft;
- a carriage configured to be movable along the arm;
- and
- a cut block configured to couple with the carriage.
A method of resecting a head of a humerus comprising:
- inserting a reamer in the humerus;
- adjusting a proximal-distal position of the cut block assembly relative to the reamer and humerus;
- clamping the cut block assembly to the reamer once a desired proximal-distal position of a cut block is achieved relative to the humerus;
- adjusting an anterior-posterior position of the cut block;
- and
- adjusting a rotational position of the cut block.
