Abstract:
Embodiments described herein relate to a method and system for dynamic spinal fixation for the correction of spinal deformities, and more specifically pertains to a method and system permitting a correction of spinal deformity without rigid fixation of the vertebral bodies. The embodiments are useful in correcting spinal deformities, including all types of scoliosis or other misalignments affecting the vertebral column. The positioning of devices and elements permits a gradual correction of a three dimensional spinal deformity through operative intervention and/or the natural growth of the vertebrae and spinal column.
Abstract:
The invention provides a method of treatment joint and disk disease comprising administering to the subject in need thereof a novel composition comprising a substantially purified plurality of cells enhanced with at least one bioactive factor capable of causing at least a portion of the plurality of cells to express an increased amount of at least one chondrogenic marker.
Abstract:
The present invention provides an implant (10) for use in fusing adjacent bony structures. The implant comprises a plurality of pieces of bone (12) and a flexible mechanism (14) including one or more flexible, elongate, biocompatible connectors interconnecting the pieces of bone.
Abstract:
The invention relates, according to one embodiment, to a graft syringe assembly for delivering bone graft material is disclosed. The graft syringe assembly comprises a syringe subassembly including a syringe barrel having an inner chamber adapted for receiving bone graft material, a plunger adapted for expelling bone graft material from the inner chamber, the plunger slidably received within the inner chamber, and a syringe adapter coupled to the syringe barrel. The graft syringe assembly further comprises a connection subassembly coupled to the syringe adapter, and a delivery tube subassembly coupled to the connection subassembly, wherein the connection subassembly is configured to allow the delivery tube subassembly to rotate relative to the syringe subassembly.

Abstract:
Devices and methods for supporting adjacent spinous processes include opposing plates movable toward one another along a cross post to contact opposite sides of each of the spinous processes, and a spacer member about the cross post contacting the adjacent surfaces of the spinous processes to resist movement of the spinous processes toward one another under spinal extension motion.
Abstract:
Embodiments for a spinal construct system including a spinal fixation plate attachable to fixture element in end-to-end fashion with a coupling mechanism that axially and torsionally constrains the first and second rods to one another. In one form, the end to end attachment arrangement is aligned along a common axis of the rods. In another form, the axes of the rods are offset laterally relative to one another.
Abstract:
One embodiment of the present application includes a spinal disk prosthesis (30) with one end portion (32a) to form a load transmitting relationship with one vertebra of a patient's spine and another end portion (32b) to form a load transmitting relationship with another vertebra of the patient's spine. A tube (52) connects the end portions (32a, 32b) together and a damping material (60) is positioned inside the tube (52) . The end portions (32a, 32b) each include a magnet (40a, 40b) to generate a corresponding magnetic field. These magnetic fields are oriented to provide a repulsive force between the end portions (32a, 32b) to provide a magnetic bearing.

Abstract:
An apparatus for use in orthopedic distraction or compression is disclosed. In the illustrated embodiments, two arms are provided that are connected by a rod or bar with a mechanism that enables the arms to be brought toward or away from each other. At the end of each arm, a tip for connecting to a bone implant is provided. The tips are pivotable with respect to the arms, and have an opening with a tab that allows insertion of an implant head having branches defining a channel. Once the tips are appropriately positioned, connected and locked to the bone implants, the mechanism can be operated to move the arms together in compression or apart in distraction.
