摘要： An interbody fusion device in one embodiment includes a tapered body defining a hollow interior for receiving bone graft or bone substitute material, The body defines exterior threads which are interrupted over portions of the outer surface of the device. The fusion device defines truncated side walls so that on end view the body takes on a cylindrical form. The side walls are provided with vascularization openings, and the body wall device includes opposite bone ingrowth slots extending through the interrupted thread portion of the body. In another embodiment, the tapered body is solid and formed of a porous biocompatible material having sufficient structural integrity to maintain the intradiscal space and normal curvature. The material is preferably a porous tantalum having fully interconnected pores to facilitate complete bone tissue ingrowth into the implant. An implant driver is provided which engages the truncated side walls to complete the cylindrical form of the implant at the root diameter of the interrupted threads, to thereby facilitate threaded insertion of the implant to the intra-discal space between adjacent vertebrae. Methods for posterior and anterior insertion of the fusion device are also disclosed.

摘要： A laparoscopic surgical technique is provided for preparing a site for implantation of a fusion device or implant. In accordance with one embodiment of the technique, a laparoscope is provided having an outer sleeve with distraction fingers at one end to distract the disc space. The laparoscope includes a laparoscopic port at its opposite end through which instruments and implants are inserted. The laparoscope provides a sealed working channel to the disc space, through which the disc space is distracted, the vertebral endplates and surrounding disc is reamed, and the fusion device inserted. The laparoscope is alternately engaged within bilateral locations in the disc space for insertion of a pair of fusion implants. A switching sleeve extends through the laparoscope to protect the tissue at the surgical site as the laparoscope is moved between the bilateral fusion locations.

摘要： A system and method for anterior fixation of the spine utilizes a cylindrical implant engaged in the intradiscal space at the cephalad and caudal ends of the construct. The implants are cylindrical fusion devices (10) filled with bone material to promote bone ingrowth and fusion of the disc space. An attachment member (40) is connected to each of the fusion devices (10) and a spinal rod (50) is connected to each of the attachment members using an eyebolt assembly (53, 54, 55). In a further inventive method, a revision of the construct is achieved by removing the fusion devices. Each fusion device is engaged by an elongated guide member (62) over which a cylindrical trephine (70) is advanced. The trephine (70) is used to extract a core (84) of bone material around the fusion implant, while the guide member (62) is used to remove the bone core (84) containing the fusion implant (10). In another aspect of the invention, a removal insert (90, 90') is provided that engages an implanted fusion device (10). The removal insert (90, 90') can be used to guide the trephine (70) around the fusion device, and is connected to a removal tool (100) once the bone core is created. The removal tool (100) includes a shaft (101) attached to the removal insert (90, 90'), and a slap hammer (104) slidably mounted on the shaft.

摘要： Laterally expanding vertebral spacer devices are provided for repairing damaged vertebral discs. The vertebral spacer devices maintain the height of a distracted vertebral disc space while providing stability to the spine. In one form of the invention, a vertebral spacer device is provided with a first arm movably coupled to a second arm. The first and second arms are laterally expandable from a first width for insertion into the disc space to a second width after insertion into the disc space. The first and second arms also define a cavity therebetween for placement of bone growth material.

摘要： A removable protective covering is provided that can be secured about an external fixation device on the upper or lower extremity of a patient. The covering includes a fabric form that is sized and configured to accommodate varying sizes of external fixation devices and uses readily engageable/releasable closure elements or fasteners to securely engage the covering about the fixator and the extremity. A drawstring closure may be provided at the open ends of the covering to tighten the end about the patient's limb. Ventilation features may be provided including vents with and without additional devices to generate air flow through the covering. The covering for a lower extremity fixation device may be configured for removably attachment to a foot plate and the foot plate itself may be configured to support or attach to the fixation device.

摘要： This invention relates to implants formed from donor bone for use in lumbar interbody fusion procedures and instruments for performing such procedures. The implants are formed to include a concave surface formed from a portion of the medullary canal of a long bone. The concave surface defines a recess in the implant that serves as a depot for osteogenic material. Specific instruments for inserting the implants prepared according to this invention and for preparing the intervertebral space to receive the implants are also provided.
