Abstract
Exemplary microfracture pick systems may include a microfracture pick, a strike plate, and a punch extension. The strike plate may be secured to a handle of the microfracture pick, and the punch extension is connectable to the strike plate. The punch extension is configured to apply an “off-axis” impact force to the microfracture pick. The “off-axis” impact force is generally aligned with an axis of a strike tip of the microfracture pick, thereby substantially preventing the strike tip from skiving across a bone surface during surgical uses.
Claims19
A surgical method, comprising:
- securing a strike plate to a handle and a shaft of a microfracture pick, wherein securing the strike plate to the shaft includes positioning the shaft within a slotted attachment portion of the strike plate;
- securing a punch extension to the strike plate;
- and
- striking the punch extension, thereby applying an off-axis impact force to the microfracture pick to form a microfracture in a bone surface.
A surgical method, comprising:
- attaching a strike plate to a microfracture pick, wherein attaching the strike plate includes securing a first portion of the strike plate to a handle of the microfracture pick and securing a second portion of the strike plate to a shaft of the microfracture pick, wherein securing the second portion of the strike plate to the shaft includes positioning the shaft within a first slotted attachment portion of the strike plate;
- securing a punch extension to the strike plate, wherein securing the punch extension includes inserting a threaded tip of the punch extension into a threaded opening of the strike plate;
- and
- striking an impact head of the punch extension to form a microfracture in a bone surface.
A surgical method, comprising:
- securing a strike plate to a handle of a microfracture pick by positioning a pin of the handle within a non-threaded through-opening of the strike plate;
- securing the strike plate to a shaft of the microfracture pick by positioning the shaft within a first slotted attachment portion of the strike plate;
- securing a punch extension to the strike plate by threading a threaded tip of the punch extension into a threaded opening of the strike plate;
- and
- striking an impact head of the punch extension to form a microfracture in a bone surface.
