    摘要: An improved apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. An alignment guide in accordance with the present invention is provided to facilitate alignment of instruments used to create a cavity in the bone for reception of the femoral implant and to facilitate size selection of the femoral implant. The alignment guide of the present invention includes a reference element and pattern arms having geometries which track an anatomical structure.

    摘要: A plurality of expandable fixation devices (EFDs) for minimally invasive surgery. The EFDs use an expanding deformation of the device to achieve a mechanical interference with the environment, e.g., bone. The shape of expansion can be controlled by many factors including the original geometry of the part, the geometry of material removed from the part, and the amount of deformation applied to the part. The EFD may be a relatively large anchor-type fixation device generally characterized by a single set of long longitudinal cuts parallel to a central axis of the device or concentric to a central curve of the device. The EFD may alternatively be a relatively small anchor-type fixation device generally characterized by multiple sets of shorter longitudinal cuts parallel to a central axis of the device or concentric to a central curve of the device. The EFD may also be a screw-type fixation device generally characterized by multiple rotationally indexed cuts in a helical pattern. The cuts define intermediate material regions which form protrusions on the EFD when deformed and, taken together, form a non-continuous helical thread to anchor the EFD in a bone.

    摘要: An expandable reamer includes, in one exemplary embodiment thereof, a cannulated shaft and a plurality of straight cutting blades having deformable points. The blades are hingably outwardly rotatable at the deformation points between a contracted position and an expanded position. In the contracted position, the blades are substantially parallel to the longitudinal axis of the cannulated shaft and, in the expanded position, the blades have at least a portion oriented radially outward from the longitudinal axis, thereby forming a larger diameter cutting surface in the expanded position and in the contracted position. The blades are formed from a portion of the cannulated shaft by, e.g. milling longitudinally extending slots through the wall of the cannulated shaft, the slots serving as flutes dividing the cutting edge and trailing edge of each adjacent blade. Each blade may also include more than one segment arranged along its length, the segments coupled by deformation points. The expandable reamer may be used for cutting a cavity in a bone or other structure that is larger than the diameter of the entry point into the bone and greater than the diameter of the contracted reamer.

    摘要: An instrument, and method for using the same, for treating and repairing a vertebral body, which includes a steerable shaft and a distal end portion. The steerable shaft defines a longitudinal axis and includes a proximate portion and a flexible portion along the length. The distal end portion extends from the steerable shaft with an initial diameter, in the collapsed state, and has one or more expanded diameters. After inserting the instrument into the vertebral body, the flexible portion permits the distal end portion of the steerable shaft to be steered away from the longitudinal axis toward a center region within the vertebral body. A cutting surface upon the distal end portion is used to ream cancellous bone within the vertebral body and to create a single void which is off-set form the initial access axis.

    摘要: A flexible shaft. In exemplary embodiments, the flexible shaft can be used for the transmission of rotary motion and/or curvilinear guidance. In one embodiment, the flexible shaft includes a plurality of shaft segments linked together via at least one flexible elongate member. The shaft segments are spaced along the at least one flexible elongate member. Some of the shaft segments are displaceable relative to the at least one flexible elongate member. Orbiting of the at least one elongate member about a central axis of the shaft induces rotation of the shaft segments about the central axis, thereby effecting rotation of the flexible shaft.
