Abstract: A holding device for assembling orthopaedic implants includes: a stand including a columnar structure with an opening formed in the structure and configured to accept a stem and a groove formed in the structure that is configured to accept a portion of an orthopaedic implant to rotatably lock the orthopaedic implant in the opening and a base coupled to the structure and configured to stabilize the structure on a surface; and an angle set including a ring rotatably coupled to the structure and a fork configured to engage the orthopaedic implant and carried by the ring.

Abstract: A milling assembly for orthopaedic surgery includes: a milling body including a coupling section with a body coupler, a pilot stem extending from the coupling section, an exterior wall, and a window formed in the exterior wall; and a milling frame that is coupled to the milling body. The milling frame includes a frame coupler that is coupled to the body coupler and a reamer guiding section. The reamer guiding section has a reamer slot that is aligned with the window of the milling body when the frame coupler is coupled to the body coupler.

Abstract: A surgical self-retaining screwdriver for the temporary securing of a bone fastener, wherein the tip of the screwdriver includes at least one deflection member which provides a frictional fit when the fastener is coupled to the screwdriver. A bone fastener is also provided which includes an undercut that is capable of temporarily retaining the at least one deflection member of the screwdriver. The invention provides a reliable means for securely holding a fastener to a screwdriver during insertion or extraction, and for easy removal of the screwdriver from the fastener after insertion.

Abstract: A patient specific implant alignment guide assembly includes an anatomical reference component and a guide component. The anatomical reference component includes at least one matching feature shaped and dimensioned to match and complement a specific feature of an anatomic location. The anatomical reference component further has one or more protrusions and is fabricated based on one or more images of the anatomic location where the implant is to be implanted. The guide component includes one or more attachment protrusions that are shaped and dimensioned to match and interface with the one or more protrusions of the anatomical reference component. The guide component is attached to the anatomical reference component by matching and attaching the one or more attachment protrusions of the guide component to the one or more protrusions of the anatomical reference component.

Abstract: A modular bone resection guide system includes a positioning base configured to be attached to a bone, a modular resection block configured to be removably attached to various locations of the positioning base and a cutting tool configured to be supported and guided by the modular resection block while cutting the bone.

Abstract: A medical sterilization container valve and method of making the same is provided. The medical sterilization container valve includes a valve housing affixed to a medical sterilization container. A first valve portion is attached to the valve housing. A second valve portion is proximate to the first valve portion, wherein the second valve portion is movable between at least a first position and a second position. A shape metal alloy (SMA) device is connected with the second valve portion, wherein the SMA device moves the second valve portion between the first and second positions.

Abstract: An orthopaedic reamer including an at least partially hemispherical cutting head which is rotatable about a primary axis and at least one deployable wing connected to the cutting head. Each of the deployable wings are pivotable about a corresponding secondary axis. At least one corresponding secondary axis is in the same plane as the primary axis.

Abstract: A surgical driver including an open frame and a plurality of drive shafts rotatably routed in said open frame.

Abstract: An angled driver assembly including a rotatable shaft rotatable about a first axis, a rotatable cutting device rotatable about a second axis, the first rotatable portion being coupled to the second rotatable portion, a reference device associated with the rotatable cutting device and an indicator linked to the reference device. The indicator indicates a position of the rotatable cutting device relative to the reference device.

Abstract: An acetabular instrument alignment guide for aligning at least one orthopaedic instrument relative to an acetabulum in a pelvis. The acetabular instrument alignment guide includes an interchangeable head configured for positioning within the acetabulum where the interchangeable head has a primary axis. A drill guide is releasably connected to the interchangeable head. The drill guide includes a drill bore offset from the primary axis, and the drill bore is configured for aligning a drill relative to the pelvis. The acetabular instrument alignment guide further includes at least one reference pin and an instrument guide connected to the at least one reference pin, the instrument guide being both rotatable and translatable relative to the at least one reference pin. The reference pin is configured for placement in at least one hole in the pelvis produced by the drill.

Abstract: An orthopaedic reamer including an at least partially hemispherical cutting head which is rotatable about a primary axis and at least one deployable wing connected to the cutting head. Each of the deployable wings are pivotable about a corresponding secondary axis. At least one corresponding secondary axis is in the same plane as the primary axis.

Abstract: An orthopaedic reamer assembly, which includes a reamer and a flexible shaft connected to the reamer. The flexible shaft has both a longitudinal axis and a longitudinal length. The flexible shaft is comprised of a rigid material. The flexible shaft has a low ratio of an area moment of inertia about an axis perpendicular to the longitudinal axis versus the longitudinal length, the low ratio provides a flexibility in the flexible shaft.
