20080228190 | IN SITU PATELLAR FIXING SYSTEM - 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. | 09-18-2008 |
20090171399 | Bone Plate with Complex, Adjacent Holes Joined by a Relief-Space - A bone plate is described which is adapted for use in situ to fix a spatial relationship of at least two bone parts. The bone plate 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 distance d 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 (r | 07-02-2009 |

20090281572 | DYNAMIC INTERVERTEBRAL STABILIZATION SYSTEM - A vertebral dynamic stabilization system is used to fix the positional relationship of adjacent vertebrae of the spine. The vertebrae stabilization system includes at least two pedicle screws, with an interconnecting rod disposed therebetween, the pedicle screws each having a threaded shaft to be screwed into a vertebra segment, and a screw head adapted to securely receive the interconnecting rod. The system allows some compression and extension of the vertebrae relative to each other, while still maintaining the overall positional relationship within an appropriate range. | 11-12-2009 |

20090318922 | REAMER SPINDLE FOR MINIMALLY INVASIVE JOINT SURGERY - 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. The adjustment is desirable in order to accommodate operating on the left or right side of the patient, standing behind or in-front of the patient, or the use of a different surgical approach. Further, adjustment is important to accommodate the differing needs of surgeons who are naturally left or right handed. | 12-24-2009 |
