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： An improved method and 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. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps. After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur. After preparation of the femoral cavity, a femoral implant in accordance with the present invention is inserted into the aforementioned cavity in the femur. The femoral implant is thereafter secured in the femur, with portions of the implant extending into and being secured within the femoral head and portions of the implant extending into and being secured within the femoral shaft.

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.

To optimally position the femoral implant, a minimally invasive incision is aligned with the greater trochanter and the wound is developed to expose the greater trochanter. Various reamers are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur.

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.
摘要翻译：用于微创手术的多个可扩张固定装置（EFD）。 EFD使用装置的膨胀变形来实现与环境（例如骨）的机械干扰。膨胀的形状可以通过许多因素来控制，这些因素包括部件的原始几何形状，从部件移除的材料的几何形状以及施加到零件上的变形量。 EFD可以是相对大的锚固固定装置，其通常特征在于平行于装置的中心轴线或与装置的中心曲线同心的单组长纵向切口。 EFD可以替代地是相对较小的锚式固定装置，其通常的特征在于平行于装置的中心轴线或与装置的中心曲线同心的多组较短纵向切口。 EFD还可以是螺旋型固定装置，其通常以螺旋图案的多个旋转分度切口的特征。切口限定了当变形时在EFD上形成突起的中间材料区域，并且一起形成非连续的螺旋螺纹以将EFD锚固在骨中。

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： A bone fracture fixation system comprising a metallic bone plate having a first composition comprising titanium or a titanium alloy and an opening for receiving a metallic fastener that has a second composition comprising titanium, a titanium alloy, or a stainless steel, and is sized to be received in the opening, and a cold-sprayed metallic coating either within the opening or on the metallic fastener is provided. The cold-sprayed metallic coating comprises a biocompatible metallic material having a third composition different than the first and second compositions. When the metallic fastener is inserted into the opening to stabilize a bone fracture, the cold-sprayed metallic coating may substantially prevent bonding or one or more types of corrosion between the metallic fastener and the metallic bone plate. In another embodiment, the cold-sprayed metallic coating comprises at least one of a cobalt-chrome alloy, gold, a gold alloy, silver or a silver alloy.
