摘要:
A bone screw comprises a threaded shank including a distal end portion and a proximal end portion, and defining a first threaded section extending from the distal end portion toward the proximal end portion and adapted for anchoring in cancellous bone. A second threaded section extends contiguously from the first threaded section toward the proximal end portion The second threaded section has a finer thread pattern relative to the first threaded section. In one embodiment, the first threaded section includes a first helical threading defining a single lead thread pattern for anchoring in cancellous bone, and the second threaded section includes a second helical threading interleaved with the first threading to define a duel lead thread pattern for engagement in cortical bone. In a further embodiment, the bone screw includes a head portion extending from the threaded shank and configured for coupling to a spinal implant.

An orthopedic implant is disclosed having at least one passage for an elongated member that is compressible. In certain embodiments, multiple compressible elongated member passages may be provided, or an elongated member passage may be U-shaped and closable by a closure member. Split ring members may be provided in compressible passages and around elongated members. A bone anchor may be connected to the implant so that locking the anchor to the implant compresses one or more of the elongated member passages.

A religious display structure includes two or more removably interconnected wall panels forming a freestanding enclosure for accommodating one or more users. Each wall panel includes a visual 3-dimensional photographic image formed on the front surface of the wall panel where the images on all of the wall panels form religious scenery depicting a place of worship for the one or more users. In one embodiment, the religious scenery is selected from a church, a chapel, a temple, or a synagogue. The enclosure formed by the wall panels can be a partial enclosure or a complete enclosure forming an enclosed space. In one embodiment, the religious display structure is made of plastic and the structure is made for easy assembly and disassembly. The religious display structure can be used in various settings, such as a home or an office, to provide a place of worship for the user.

A caddy that is hitchable to a self-propelled power mower which comprises a pair of wheels and an axle for coupling the wheels including a main axle member which is positioned below the wheel center, an operator platform is mounted on the main axle such that the operator is positioned over the axle. The platform is located such that wheel centers are located in a vertical plane which substantially laterally bisects the platform so that the shifting rearwardly of the operator's weight cause concentration of the load on the wheels. A towbar is fixed to the axle and removably hitched to the mower. The wheel centers are located rearwardly from the main axle so that when the operator is normally positioned on the caddy a torque about the wheels centers is created that causes the towbar to apply a force at the mower.
