Orthopedic implants, instrument systems and methods of use
An orthopedic implant includes an upper portion, a central portion having a greater lateral dimension than that of the upper portion, and a lower portion having a greater lateral dimension than the central portion. The upper portion, the central portion and the lower portion each may have at least one fixation aperture. Further, the upper portion, the central portion and the lower portion may each be non-linear and/or curved relative to at least one plane. An instrument having a body that includes a housing. The body includes a platform, at least one retention mechanism for holding the implant on the platform, an adjustment mechanism to adjust the height of the platform relative to the top surface of the housing, and a lid coupled with the housing with the top surface of the housing and the lid defining a slot configured to receive a cutting instrument.
1 . An orthopedic instrument, comprising:
a body comprising a housing, wherein the body further comprises:
a platform configured to receive an implant;
at least one retention mechanism configured to retain the implant at least partially on the platform;
an adjustment mechanism configured to adjust a height of at least a portion of the platform relative to a top surface of the housing; and
a lid hingedly coupled with the housing, wherein the top surface of the housing and the lid define a slot configured to receive at least a portion of a cutting instrument.
2 . The orthopedic instrument of claim 1 , wherein the implant is a biological graft implant.
3 . The orthopedic instrument of claim 2 , wherein the implant has a substantially wedge-shaped geometry.
4 . The orthopedic instrument of claim 1 , wherein the at least one retention mechanism comprises a pair of retention mechanisms configured to contact the implant on opposite sides of the implant.
5 . The orthopedic instrument of claim 1 , wherein the lid comprises a window coupled with the lid, wherein the window is transparent.
6 . The orthopedic instrument of claim 5 , further comprising at least one actuator positioned at least partially within the housing, wherein at least a first portion of the at least one actuator extends laterally through an opening in a lateral wall of the housing and at least a second portion of the at least one actuator extends vertically through an opening in the implant.
7 . The orthopedic instrument of claim 6 , wherein the at least one actuator is a pair of actuators positioned on opposite lateral sides of the housing.
8 . The orthopedic instrument of claim 7 , wherein each of the actuators is configured to releasably engage the lid so as to retain the lid in a closed position.
9 . The orthopedic instrument of claim 8 , wherein manipulation of the actuators disengages the actuators from the lid.
10 . The orthopedic instrument of claim 9 , wherein the lid comprises a button releasably coupled with an engagement element.
11 . The orthopedic instrument of claim 10 , wherein manipulation of the button biases the engagement element such that the engagement element contacts the implant so as to retain the implant in a desired position.
12 . A surgical system, comprising:
an instrument, comprising:
a body comprising a housing, wherein the body further comprises:
a platform configured to receive a biologic implant;
at least one retention mechanism configured to retain the biologic implant at least partially on the platform;
an adjustment mechanism configured to adjust a height of at least a portion of the platform relative to a top surface of the housing; and
a lid hingedly coupled with the housing, wherein the top surface of the housing and the lid define a slot configured to receive at least a portion of a cutting instrument;
a first implant configured to be reshaped within the housing of the instrument; and
a second implant.
