Abstract
Illustrative embodiments of orthopedic implants and methods for surgically repairing hammertoe are disclosed. According to at least one illustrative embodiment, an orthopedic implant includes a proximal segment comprising a number of spring arms forming an anchored barb at a first end of the implant, a distal segment extending between the proximal segment and a second end of the implant, and a central segment disposed between the proximal and distal segment.
Claims23
An orthopedic implant comprising:
- a proximal segment comprising at least three spring arms forming an anchored barb at a first end of the implant, wherein first threading extends around outer surfaces of at least a portion of each spring arm and the first threading includes minor and major diameters;
- and
- a distal segment extending between the proximal segment and a second end of the implant and including second threading extending along at least a portion of the distal segment.
An orthopedic implant comprising:
- a proximal segment comprising at least two spring arms forming an anchored barb at a first end of the implant, wherein first threading extends around outer surfaces of at least a portion of each spring arm and the first threading includes minor and major diameters;
- and
- a distal segment extending between the proximal segment and a second end of the implant and including second threading extending along at least a portion of the distal segment, wherein the second threading includes minor and major diameters and at least two of the minor diameters increase between the second end and the proximal segment.
A method of removing an orthopedic implant from a patient, the method comprising the steps of:
- severing an orthopedic implant in a central segment of the orthopedic implant that is disposed between a proximal segment configured for implantation within a proximal phalanx of a patient and a distal segment opposite the proximal segment and configured for implantation within a middle phalanx of a patient;
- inserting a tool into the proximal or distal segment of the orthopedic implant;
- and
- rotating the tool to remove the proximal or distal segment of the orthopedic implant from the proximal or middle phalanx, respectively.
A tool for implantation of an orthopedic implant having a proximal segment having at least three arms spaced from one another by recesses, the three arms configured for implantation with a proximal phalanx of a patient and a distal segment opposite the proximal segment and configured for implantation within a middle phalanx of the patient, the tool comprising:
- a body;
- at least three arms extending from an end of the body, wherein each of the arms is sized and shaped to fit within one of the recesses disposed between the three arms in the proximal segment of the implant.
