    摘要： Method for percutaneous fixation of a pair of vertebrae comprising posterolaterally entering the back percutaneously with a plurality of pedicle screws (1), screwing each screw into the medullary canal (2) of the pedicles (3) of adjacent thoracic and/or lumbar vertebrae or the pedicles of the L5 and S1 vertebrae, to a position where the proximal end (1b) thereof lies adjacent the fascia of the patient; inserting pedicle screw linkages (7) under the skin of the back and detachably securing the linkage means to the proximal ends of the screws on the same side of the spinous processes of vertebrae. A kit is provided for percutaneous fixation of vertebrae, comprising a plurality of pedicle screws (1) of different sizes, yet of a size to enable the distal end (1a) of each screw to be screwed into the medullary canal of a pedicle of a vertebra with the proximal end (1b) thereof lying adjacent the fascia of a patient.

    摘要： There is disclosed a pedicle screw (1) for percutaneous internal fixation of vertebrae, comprising proximal and distal ends (1b, 1a) and sized to enable the distal end (1a) to be screwed into the medullary canal (2) of a pedicle (3) of a vertebra (4) with the proximal end (1b) thereof lying adjacent the fascia (20) of a patient. There is also disclosed a kit for percutaneous fixation of vertebrae of a patient, comprising a plurality of pedicle screws (1) of different sizes, yet of a size to enable the distal end (1a) of each screw (1) to be screwed into the medullary canal (2) of a pedicle (3) of a vertebra (4) with the proximal end (16) thereof lying adjacent the fascia (20) of a patient.
    There is additionally described a method for percutaneous fixation of a pair of vertebrae of a patient, which comprises posterolaterally entering the back of a patient percutaneously with a plurality of pedicle screws (1), screwing each pedicle screw (1) into the medullary canal (2) of the pedicles (3) of adjacent thoracic and/or lumbar vertebrae or the pedicles of the L5 and S1 vertebrae, to a position where the proximal end (1b) thereof lies adjacent the fascia (20) of the patient; inserting pedicle screw linkages (6, 7) under the skin of the back of the patient and detachably securing the linkage means to the proximal ends (1b) of the screws (1) on the same side of the spinous processes of the vertebrae to restrict relative movement between the vertebrae.

    摘要： There is disclosed a coated prosthesis that can be tailored to avoid the problem of bone resorption caused by stress shielding. The permanent, load-bearing skeletal replacement prosthesis (10) is coated or covered with a bioabsorbable polymer (30) at selected sites on its surface so that bone affixation is preferentially delayed at these covered sites and bone adjacent to uncoated areas are not stress shielded. Thus, resorption is avoided. When the bioabsorbable polymer is gradually absorbed away, bone affixation takes place on the exposed surfaces, as needed.
