Abstract
Sheaths for implantable fixation devices have a flexible body with a perforated wall, and an interior of the body is sized and shaped to receive the fixation device. Sheaths include a plurality of flexible or inflexible tubes arranged to form a ring, where the central cavity defined by the ring is sized and shaped to receive the fixation device.
Claims34
A combination comprising:
- a sheath including a flexible body defining a tube having two ends, each end having an opening of substantially the same dimensions, the tube having a relieved wall and defining an interior sized and shaped to receive both a shaft of a bone screw and a soft tissue graft;
- and
- a bone screw having a shaft sized and shaped to fit within the interior of the sheath.
A combination comprising:
- a sheath including a flexible body defining a tube having two ends, each end having an opening of substantially the same dimensions, the tube having a perforated relieved wall defining an interior sized and shaped to receive a soft tissue fixation device that is configured to be inserted into a bone tunnel;
- and
- the soft tissue fixation device.
A combination comprising:
- a sheath including a flexible body defining a tube having two ends, each end having an opening of substantially the same dimensions, the tube having a relieved wall with a major portion of the wall being open, the wall defining an interior sized and shaped to receive a soft tissue fixation device that is configured to be inserted into a bone tunnel;
- and
- the soft tissue fixation device.
A combination comprising:
- a sheath including a flexible body having a roughened exterior surface and defining a tube having two ends, each end having an opening of substantially the same dimensions, the tube having a relieved wall and defining an interior sized and shaped to receive a soft tissue fixation device that is configured to be inserted into a bone tunnel;
- and
- the soft tissue fixation device.
A combination comprising:
- a sheath including a flexible body defining a tube having two ends, each end having an opening of substantially the same dimensions, the tube having a relieved wall and defining an interior sized and shaped to receive a fixation device and a soft tissue graft;
- and
- the fixation device.
A combination comprising:
- a sheath including a flexible body defining a tube having two ends, each end having an opening of substantially the same dimensions, the tube having a relieved wall and defining an interior sized and shaped to receive a bone screw;
- and
- a bone screw having a shaft sized and shaped to fit snugly within the interior of the sheath, the shaft including generally rounded screw threads.
A combination comprising:
- a sheath including a flexible body having two ends, each end having an opening of substantially the same dimensions, the body having a relieved wall and defining an interior sized and shaped to receive the shaft of a bone screw, and
- the bone screw having a shaft sized and shaped to fit snugly within the interior of the sheath, the shaft including generally rounded screw threads.
