Patent number: 11246624Abstract: The broach or rasp holder tool with reduced rasp moment includes an angled strike plate with an optional curved or spheroidal surface and/or an angled withdrawal plate having a contact surface for receiving a generally perpendicular strike force that generally aligns with a point along a rasp for substantially eliminating a moment applied thereto while broaching the intramedullary canal in preparation for implanting a prosthetic stem during joint replacement surgery.Type: GrantFiled: November 7, 2016Date of Patent: February 15, 2022Assignee: Joint Development, LLCInventors: James T. Grutta, Dermott J. McHugh, Chris A. Weaber

Patent number: 10624753Abstract: The orthopedic implant locking system may include an eccentric tibial stem having an engagement rod selectively threadingly engageable with a tibial baseplate, a lock housing securable in rotatable and substantial vertical constrained relation relative to the tibial stem, and an extension lock selectively threadingly engageable with the lock housing and including an inner passage keyed to selectively slidably engage the engagement rod in flush engagement therewith. The extension lock may extend or contract in response to rotational movement of the lock housing simultaneously while the extension lock remains in substantial non-rotatable relation relative to the tibial stem.Type: GrantFiled: August 10, 2017Date of Patent: April 21, 2020Assignee: Joint Development, LLCInventors: Dermott J. McHugh, Chris A. Weaber, Eric M. Dacus, James T. Grutta

Patent number: 10619238Abstract: The process for producing an orthopedic implant having an integrated silicon nitride surface layer includes steps for positioning the orthopedic implant inside a vacuum chamber, mixing nitrogen gas and vaporized silicon atoms in the vacuum chamber, emitting a relatively high energy beam into the mixture of nitrogen gas and vaporized silicon atoms in the vacuum chamber to cause a gas-phase reaction between the nitrogen gas and the vaporized silicon atoms to form reacted precipitate silicon nitride molecules, and driving the precipitate silicon nitride molecules with the same beam into an outer surface of the orthopedic implant at a relatively high energy such that the precipitate silicon nitride molecules implant therein and form at least a part of the molecular structure of the outer surface of the orthopedic implant, thereby forming the integrated silicon nitride surface layer.Type: GrantFiled: January 9, 2019Date of Patent: April 14, 2020Assignee: Joint Development, LLCInventors: Eric M. Dacus, Erin E. Hofmann

Patent number: 9844438Abstract: The femoral stem prosthesis includes a prosthesis body having a neck, stem, and porous coating receiving area. A portion of a transition between the porous coating receiving area and the stem is defined by a recess where the porous coating receiving area inwardly extends by a depth relative to the stem while the porous coating receiving area is approximately flush with the stem about a remainder of the transition between the porous coating receiving area and the stem. A porous coating overlying the porous coating receiving area has a thickness approximately equal to the depth of the recess to define a smooth transition between the porous coating and the stem along the portion of the transition by the at least one recess and a collar outwardly extending relative to the stem by approximately the thickness along the remainder of the transition between the porous coating receiving area and the stem.Type: GrantFiled: August 29, 2016Date of Patent: December 19, 2017Assignee: Joint Development, LLCInventors: Dermott J. McHugh, Eric M. Dacus

Patent number: 9289305Abstract: A total knee arthroplasty includes a symmetric femoral prosthesis for articulating with a tibial prosthesis in the left or right leg of a patient. The symmetric femoral prosthesis includes an anterior flange having a symmetric and upwardly diverging, generally V-shaped, double Q-angle trochlear groove formed in an anterior side thereof for accommodating natural Q-angle tracking of a natural or prosthetic patella when the symmetric femoral component is surgically implanted in either the left or right leg of a patient. In a preferred form, the double Q-angle trochlear groove is formed with an angle of + or ? about 10°, for a total groove angle of about 20°.Type: GrantFiled: July 9, 2012Date of Patent: March 22, 2016Assignee: Joint Development, LLCInventor: Eric M. Dacus
