Publication number: 20090318922Abstract: An adjustable reamer spindle is provided to aid the surgeon in controlling the instrument. The reamer spindle is easily disassembled for cleaning. The spindle has a repositionable handle, a locking ring, and an elastic device. The elastic device biases against a handle locking mechanism that locks the repositionable handle at angular positions about an axis of the spindle. The elastic device further biases a locking ring into a locked position. The locking ring aids in holding the reamer spindle together. Removal of the locking ring against an elastic bias of the elastic means unfastens an end of the assembly in order to facilitate disassembly and/or cleaning. Adjustment of the position of the handle about the spindle enables the palm/grip of each hand to be changed in order to provide maximum control in different orientations.Type: ApplicationFiled: May 5, 2005Publication date: December 24, 2009Applicant: Precimed S.A.Inventors: Andre Lechot, Yves Desarzens, Hugh Davies, Patrick White

Publication number: 20090292318Abstract: A bone plate (10) is described which is adapted for use in situ to fix a spatial relationship of at least two bone parts (80). The bone plate (10) has at least one pair of the bone screw apertures that are adjoined by a relief-space contiguous with the open space of the screw apertures themselves. An adjoined aperture pair forms a complex aperture and has a center-to-center distanced of the apertures along an axis running through the centers of the apertures. The center-to-center distance d is equal to or greater than the sum of the radii (r1+r2) of the heads of the individual bone screw used with the aperture pair. At least one of the screw apertures (24) has a screw head seat (34) having at least one relief notch (84) set into a surface of the screw head seat (34). The relief notch 84 provides desirable advantages that are not similarly accomplished in their absence, such as a clearance passage for a tensioning wire 88 or a receiver for a self-locking insert 92.Type: ApplicationFiled: July 7, 2007Publication date: November 26, 2009Applicant: PRECIMED, S.A.Inventors: Patrick White, Steve Forbes, Gary Thau

Publication number: 20080228190Abstract: Disclosed is a patellar cutting jig for use in a knee joint surgical procedure. The jig grips and holds a patella in situ in spatial reference to the femur to enable the appropriate cut to be made to the patella to accurately accommodate the patello-femoral gap at the replacement knee joint. The patella jig has a referencing component that provides a landmark connection between the patella jig and the femur which enables the patella clamp of the jig to be oriented relative to the reference feature prior to gripping the patella. Thus a patella held in the clamp is fixed in the cutting jig an appropriate orientation relative to the femur prior to its resection. Cutting the patella while it is referenced to the patellar groove on the femur increases the accuracy of the resection.Type: ApplicationFiled: February 29, 2008Publication date: September 18, 2008Inventors: Eugene SHERRY, Sureshan Sivananthan, Patrick Hans Heinrich Warnke, Patrick White, Fabrice Chenaux

Publication number: 20080161813Abstract: An acetabular reamer (10, 10?, 10?) is intended in particular for the shaping of the cotyloid cavity in the event of a replacement of a hip joint by total prosthesis. The reamer (10, 10?, 10?) is typically of a truncated hemispherical form and is adapted for attachment to a reamer spindle in order to be driven in rotation about a cutter axis (11). The ability to cut a full, continuous hemisphere to the apex (12) of the hemispherical body (14) is suppressed, so as to attain the principal advantage of the invention, namely, to adequately prepare the acetabulum for receipt of a prosthesis while minimizing the possibility of breakthrough of the fovea/acetabular fossa. The reamer (10, 10?, 10?) has an interface 16 typically made tip of cross bars (20) which a holder engages for rotationally activating the reamer for cutting.Type: ApplicationFiled: December 27, 2007Publication date: July 3, 2008Applicant: Precimed S.A.Inventors: Eugene SHERRY, Sureshan Sivananthan, Patrick Hans Heinrich Warnke, Andreas Baenziger, Patrick White, Patrick Berdoz, Fabrice Chenaux

Publication number: 20080051791Abstract: A bone plate(s) of complex form is provided, particularly suited to tibial plateau-leveling osteotomy and a distal femoral osteotomy. The bone plate has a main longitudinal axis, a bone-contacting bottom side (not shown) and a top side with at least three sets of overlapping holes which communicate through the plate from the top to the bottom side. The sets of overlapping holes define threaded apertures having multifaceted surfaces. When applied to a bone, two sets of such overlapping holes are located so as to lie on opposite sides of an osteotomy site and on the tibial plate; a third is aligned at approximately 60 degrees with the longitudinal axis. The configuration of this complex bone plate vary, depending on the physiology of the patient. An object of the invention is to provide an orthopaedic surgeon greater flexibility of choice in that a threaded peg providing secure fixing can be positioned at any interval along the bone plate, including at its extreme ends or on its elbow.Type: ApplicationFiled: October 31, 2007Publication date: February 28, 2008Applicants: Precimed S.A.Inventors: Robert YOUNG, Patrick White, Michael Khowaylo
