摘要:
Methods for altering the natural history of degenerative disc disease and osteoarthritis of the spine are proposed. The methods focus on the prevention, or delayed onset or progression of, subchondral defects such as bone marrow edema or bone marrow lesion, and subchondral treatment to prevent the progression of osteoarthritis or degenerative disc disease in the spine and thereby treat pain.

摘要:
Systems and methods for the treatment of a joint are provided. These systems and methods may also include a subchondral treatment of bone of the same joint. These joint treatment methods may be non-surgical or surgical. Also provided are devices and instruments associated with the methods.

The specification discloses a word puzzle game whose elements are: a substrate which carries a letter field of spaces defined by lines on the substrate; a letter in each space; means associated with the spaces for indicating the removal from play of the letters after they have been used; a set of word clues associated with and keyed to the letter field; and a puzzle statement whose solution is dependent upon the proper solution of said word clues and which is revealed by the letters and the unused spaces of the letter field. All word clues and puzzle statement solutions are lettered in sequence, but may run in any direction--up, down, across, backward or diagonally, and no letters are used more than once.In play, the player considers word clues, solves each clue by finding the word answer in the unused letters in the letter field, indicates their removal from play by marking the means provided for that purpose, then considers a conundrum which is posed and finds the answer in the words which can be formed from the remaining unused letters in the letter field.
摘要:
An instrument for controlled delivery of a device to a target area near a defect of a bone is provided. The instrument comprises a guide frame having a plurality of device portals, each portal defining a trajectory. The guide frame further includes visual markers for aligning the guide frame to an anatomical landmark on the bone to be treated. The instrument also includes a holder for releasable attachment with the guide frame. Each device portal is configured to provide accurate and controlled delivery of the device to the target area. In one example, the markers are radiopaque, and are visualized through fluoroscopy. A method of using the instrument is also provided.
摘要:
Instruments and methods for inserting an intervertebral implant. Insertion of the implant is accomplished by grasping the implant between the arms of an insertion instrument having arms which separate from each other and close against each other onto the implant, such that the ends of the arms of the insertion instrument engage recesses of the implant. A spacer may be provided between the arms of the insertion instrument to help position the implant while held by the arms.
摘要:
Instruments and methods for preparing an intervertebral space for receiving an implant. An adjustable trial implant has an adjustable stop mechanism having a stop member connected thereto to vary the distance that a body portion of the trial implant can move into the intervertebral space. Cutting tools for forming cutouts in the adjacent vertebrae use the trial implant and/or a guide to position a cutting tool which may be a burr or a chisel. The chisel cutting tool can be moveable relative to a selected trial implant or the chisel cutting tools can be fixed onto a trial implant shaped body portion.
