Patent number: 11957363Abstract: Improved instruments for modifying a shape of a proximal femur of a patient for installation of a stem of a femoral component of a prosthetic hip during hip replacement surgery, comprising a handle including an elongated shaft extending downward approximately in a z-direction, a first offset extending from a bottom of the elongated shaft approximately in a y-direction, a second offset extending from the second offset approximately in an x-direction, and a shaping member elongated downward from the second offset approximately in the z-direction. Provided is an improved femoral broach and an improved osteotome. Also provided is a method of improving a patient's positioning during hip replacement surgery by using a variable configuration mattress for positioning the patient.Type: GrantFiled: November 30, 2021Date of Patent: April 16, 2024Assignee: SMITH & NEPHEW, INC.Inventor: David C.

Patent number: 11298189Abstract: Systems, devices and methods for guiding placement, orientation, and fixation of an orthopedic implant. Examples include a surgical guide having a first surface structured to fit within a prosthetic cup, at least one guide hole through the first surface, and an alignment structure having a contour formed from data indicative of the patient anatomy. The contour of the alignment surface is complementary to a portion of the patient anatomy in a unique orientation that aligns the guide hole with tissue suitable for receiving a fastener. The alignment structure preferably includes an arm with a first end coupled to a rim of the guide and a second end coupled to the contour. In certain implementations, the guide includes a plurality of alignment structures. Further disclosed are methods of making and using a surgical guide for aligning an orthopedic implant.Type: GrantFiled: February 13, 2020Date of Patent: April 12, 2022Assignee: Smith & Nephew, Inc.Inventors: David C.

Publication number: 20220039961Abstract: Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. Mounting members include, for example, flanges, blades, hooks, and plates. In some embodiments, the orthopedic attachments may be adjustably positionable about the base member or other attachments, thereby providing modularity for assembling and implanting the device, and various securing and/or locking mechanisms may be used between the components of the implant.Type: ApplicationFiled: October 25, 2021Publication date: February 10, 2022Inventors: Justin Steve Conway, David C.

Patent number: 11173045Abstract: A trial medical instrument for aligning an acetabular component, comprising: a first portion configured to fit within a patient's acetabulum; and a second portion extending from the first portion; wherein the second portion extends from the first portion in a direction that mimics a shape formed by a femoral implant component coupled with an acetabular implant component when a femur to which the femoral implant component is coupled is in a position relative to an acetabulum to which the acetabular implant component is coupled that is near an extent of a typical range of motion of the femur. As used herein, the phrase “extent of a typical range of motion” describes typical angular displacements of a femur as usually limited by patient anatomy.Type: GrantFiled: September 19, 2019Date of Patent: November 16, 2021Assignee: Smith & Nephew, Inc.Inventors: David C.

Patent number: 9526512Abstract: Instruments for use in anterior approach total hip arthroplasty. Instruments according to certain embodiments of the invention connect to a shaping member such as a broach, reamer or osteotome that is used to prepare the intramedullary canal of a desired femur or other bone for total hip arthroplasty. Such an instrument according to such embodiments can be configurable to allow operation on either the left or right leg, and in doing so to provide lateral offset and anterior offset of the instrument handle relative to the shaping member so that the patient's gut, musculature or other bodily portions may be avoided while still providing desired leverage and control over the shaping member to prepare the intramedullary canal.Type: GrantFiled: February 12, 2014Date of Patent: December 27, 2016Assignee: Smith & Nephew, Inc.Inventors: Jeffrey Andrew Sharp, Luke Andrew Gibson, David C.
