  • Patent number: 8784422
    Abstract: An acetabular reaming system is disclosed of the type having a driver and a tool held together by a quick-release coupling mechanism. The tool (10) has a hollow body (12) defining a domed shape with a rotational axis (14), an apex (16) aligned with the axis (14) and a hemispherical wall (18) extending from the apex (16) to an equatorial rim (20) spaced 90 degrees from the axis (14). The rim (20) has an edge (22) visible to the user that indicates the position of the tool (10) relative to the bone. A first plurality of cutting sites (24) is arrayed along the body (12) and a second plurality of cutting sites (28) is arrayed circumferentially along the edge (22). Preferably, the first plurality of cutting sites (24) present raised first teeth (30, 130, 230, 330) having a profile selected from continuous squared (30), continuous rounded (130), discontinuous squared (230) and tongued (330) profiles.

  • Publication number: 20140163561
    Abstract: 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.

  • Publication number: 20140163560
    Abstract: A trialing and preparation system for preparing a disc space between two adjacent vertebrae is provided. The system includes a guide shaft, a trialing cage or spacer, a scraper and a driving shaft. The guide shaft supports the trialing spacer within the disc space and may include an angular adjustment for such access. The scraper sleeves over the guide shaft into an abutting relationship with the adjacent vertebrae. The driving shaft is coupled to the scraper by a pivoting and reciprocation mechanism that allows angular adjustment of the scraper. Also, reciprocation of the driving shaft reciprocates the scraper through a limited sweep of motion to remove osteophytes from the vertebrae.

  • Patent number: 8734451
    Abstract: 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.

  • Publication number: 20140142420
    Abstract: An endoscopic pedicle probe for use during spinal surgery to form a hole in a pedicle for reception of a pedicle screw has an enlarged proximal end for cooperation with the hand of the surgeon and an elongate shaft terminating in a distal tip that may be pushed through the pedicle to form the hole. The tip may be detachable for replacement. An endoscope extends through the shaft and is connected with a monitor to enable the surgeon to visually observe the area being treated. In a preferred form a light means extends through the shaft to illuminate the area being treated, and in a further preferred form a conduit extends through the shaft to convey a fluid to flush the area being treated. In a further embodiment, two endoscopes are associated with the probe.

  • Publication number: 20140107653
    Abstract: An osteotome includes a connector, a first arm, a second arm, a third arm, a fourth arm and a cutting head. A coordinate system has an X axis, a Y axis, and a Z axis. The X axis, the Y axis and the Z axis are perpendicular to each other and intersect at an original point. The connector extends along the Y axis. The first arm, extending along the Y axis, connects to the second arm, extending along the plane with the X and Y axes. An angle between the first and second arms is within a range between 125 to 145 degrees. The third and fourth arms respectively extend along the Z axis and the X axis. The cutting head is parallel to the X axis and the Y axis so as to easily control the insertion angle of the osteotome for the patients with smaller face or smaller oral cavity.

  • Publication number: 20130310836
    Abstract: The present disclosure provides a cut guide for use in preparation of the distal femur to form the anterior, anterior chamfer, distal, posterior chamfer and posterior facets as well as the intercondylar box cuts utilized to prepare a femoral intercondylar box. To allow for the use of a single cutting guide to make all of these femoral osteotomies, the present disclosure implements an orthopedic guide assembly including a primary guide body with a secondary guide body rotatably connected to the primary guide body. With this configuration, the secondary guide body can be rotated into an operable position to guide a femoral osteotomy and may also be rotated into an inoperable position in which it is moved from a configuration (i.e., the operable position) in which it acts as a barrier to movement of an osteotome across a guide surface of the primary guide body.
