Abstract: A bone fusing implant device includes an elongated body extending along a longitudinal direction and having a star-shaped cross-section. The elongated body includes a central through-opening extending through the elongated body's center along the longitudinal direction and an outer surface with alternating elongated ridges and slit openings extending along the longitudinal direction. The outer surface is coated with bone growth enhancing additives.

Abstract: A surgical device includes an inner stylet component and an outer stylet component. The inner stylet component includes a first handle and an elongated rod having a proximal end attached to a bottom surface of the first handle and a distal end comprising a needle tip. The outer stylet component includes a second handle and an elongated cannula having a proximal end attached to a bottom surface of the second handle and a distal open end comprising cutting elements formed on an outer surface. The elongated rod is sized to removably fit and slide within the elongated cannula, and the first handle is configured to interlock with the second handle. Rotating the interlocked first and second handles moves forward the elongated cannula and the needle tip and cuts a profile in an insertion site with the cutting elements of the outer cannula.

Abstract: A method for inserting an interspinous spinal implant into an opened gap between first and second spinous processes of adjacent superior and inferior vertebras, respectively includes the following. First forming an opened gap between a first spinous processes of a superior vertebra and a second spinous processes of an adjacent inferior vertebra by first inserting a decompression knife into diseased areas of the adjacent superior and inferior vertebras, then cutting fascia tissue, then separating soft tissue from bone by rocking the decompression knife back and forth, and then inserting a broach cutter into the diseased areas of the adjacent superior and inferior vertebras and cutting interspinous ligament between the adjacent superior and inferior vertebras. Next, determining and selecting an appropriate sized and shaped interspinous spinal implant for the opened gap by inserting a sizing tool into the opened gap, and sizing the opened gap with the sizing tool.

Abstract: A bone fusing implant device includes an elongated body extending along a longitudinal direction. The elongated body includes a first segment having an outer surface with cortical threads, a second segment having an outer surface with cancellous threads, a top segment and a bottom segment. The first segment is adjacent to the second segment along the longitudinal direction and is configured to engage a cortical bone with the cortical threads and the second segment is configured to engage a cancellous bone with the cancellous threads. The elongated body has one or more elongated fusing gutters extending along the longitudinal direction on an outer surface of the elongated body covering the first and second segments, a central opening extending along the longitudinal direction through the elongated body's center and one or more through-openings that extend horizontally and intersect with the one or more fusing gutters.

Abstract: A bone fusing implant device includes an elongated body extending along a longitudinal direction, and has one or more elongated grooves extending along the longitudinal direction on an outer surface of the elongated body and one or more elongated ridges alternating with the one or more elongated grooves and extending along the longitudinal direction on the outer surface of the elongated body. The elongated body includes a first segment having an outer surface with cortical threads, a second segment having an outer surface with cancellous threads, a top segment and a bottom segment. The first segment is configured to engage a cortical bone with the cortical threads and the second segment is configured to engage a cancellous bone with the cancellous threads. The cortical threads and the cancellous threads are formed on the one or more elongated ridges and do not extend into the one or more elongated grooves.
