Abstract
This disclosure relates to surgical devices and methods for repairing bone defects. The defect indicators disclosed herein may be utilized to indicate a precise location of the defect associated with an articular surface of a joint.
Claims20
An assembly for preparation of a surgical site comprising:
- a trajectory guide including a guide body and a plurality of arm members distributed about a periphery of the guide body, the plurality of arm members including a set of arm members dimensioned to abut bone, the guide body having a passageway extending along a longitudinal axis, the passageway dimensioned to at least partially receive a guide pin to set a trajectory of the guide pin relative to bone, and each of the arm members moveable relative to the guide body;
- and
- a defect indicator carried by one of the arm members such that the defect indicator is moveable in an axial direction together with the respective arm member relative to the longitudinal axis, the defect indicator including a main body and a patient-specific indication member extending from the main body, the indication member dimensioned to indicate a direction relative to the longitudinal axis that corresponds to a predetermined position of a bone defect of a patient.
A kit for arthroplasty comprising:
- an orthopaedic implant dimensioned to abut bone along a surgical site;
- a trajectory assembly comprising:
- a trajectory guide including a guide body and a plurality of arm members moveable relative to the guide body, the plurality of arm members including a set of arm members configured to set a trajectory of a guide pin relative to bone;
- and
- a defect indicator carried by one of the arm members such that the defect indicator is moveable in an axial direction together with the respective arm member relative to a longitudinal axis of the trajectory guide, the defect indicator including a main body and a patient-specific indication member configured to indicate a direction relative to the guide pin that corresponds to a predetermined position of a bone defect of a patient;
- and
- a reaming assembly comprising:
- a housing configured to at least partially receive the guide pin to set an orientation of the housing relative to the surgical site;
- and
- a reaming head rotatable about a reaming axis to remove bone, wherein the reaming axis is oriented at an oblique angle relative to the assembly axis, and the reaming assembly is moveable such that a distalmost position of the reaming head is substantially positioned in the direction.
