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.
Claims21
A tool for implantation of an orthopedic implant having a proximal segment having at least three implant arms spaced from each other by recesses of the implant, the three implant arms being configured for implantation into a proximal phalanx of a patient and a distal segment opposite the proximal segment being configured for implantation into a middle phalanx of the patient, the tool comprising:
- a body defining a longitudinal axis;
- and
- at least three tool arms extending from an end of the body, wherein each arm of the tool arms is configured for fitting within one of the recesses of the implant and includes:
- a first surface extending from the body and within a first plane parallel to the longitudinal axis, and
- a second surface distal to and extending distally from the first surface, the second surface being within a second plane transverse to the longitudinal axis,
- wherein each of the first and the second surfaces extends across a full width of the arm defined within a plane extending radially from the longitudinal axis.
An orthopedic implantation tool, comprising:
- a body;
- and
- at least three tool arms circumferentially spaced 120 degrees apart from each other and extending from an end of the body, each of the tool arms defining a central plane extending radially from the body,
- wherein each of the tool arms defines a respective tip spanning a full width of each of the arms defined within the central plane, each of the tips extending in a distal direction without contacting the tips of any of the other arms.
An orthopedic implantation tool comprising:
- a body defining a longitudinal axis;
- and
- three tool arms each extending from an end of the body without contacting the other arms, wherein each of the tool arms is configured for fitting within one of the recesses of the implant and includes:
- a first surface extending from the body and within a first plane parallel to the longitudinal axis,
- a second surface distal to and extending from the first surface, the second surface being within a second plane at an angle transverse to the longitudinal axis, and
- at least a third surface within a third plane, the third plane being transverse to the second plane and the third surface being distal to the second surface, the third surface further extending from the second surface along a full width of the second surface defined within the second plane.
