Abstract
A surgical instrument for removing an implanted glenoid component from the glenoid of a patient includes a protective cannula and a flexible wire saw. The flexible wire saw is positioned in the protective cannula such that both ends of the flexible wire saw extend out of one end of the protective cannula, with a portion of the middle section of the wire saw forming a loop that extends out of the other end of the protective cannula. Surgical methods for the use of such a surgical instrument are also disclosed.
Claims19
A method of surgically removing an implanted glenoid component from the glenoid of a patient, comprising:
- positioning a flexible wire saw between a medial surface of a platform of the implanted glenoid component and the glenoid of the patient,
- reciprocating the flexible wire saw so as to cut through one or more anchors extending from the medial surface of the platform of the implanted glenoid component, and
- removing the platform of the implanted glenoid component from the glenoid of the patient such that the one or more cut anchors remain in the glenoid of the patient.
A surgical instrument for removing an implanted glenoid component from the glenoid of a patient, comprising:
- a protective cannula having a first end and a second end, and
- a flexible wire saw having a first end, a second end opposite the first end, and a middle section positioned between the first end and the second end, wherein the flexible wire saw is positioned in the protective cannula such that both the first and second ends of the flexible wire saw extend out of the first end of the protective cannula and a portion of the middle section forms a loop that extends out of the second end of the protective cannula.
A method of surgically resecting the humeral head of a patient, comprising:
- positioning a flexible wire saw in contact with the humeral head of the patient, and
- reciprocating the flexible wire saw so as to cut through the humeral head of the patient so as to create a substantially planar surgically prepared surface.
