Abstract
Proposed is a spinal cage. The spinal cage includes a bone support portion configured to be disposed between a first vertebra at an upper side and a second vertebra at a lower side to support the first vertebra, a base portion positioned at a lower side of the bone support portion to come in contact with the second vertebra, and a sidewall portion which has an upper side end connected to an edge of the bone support portion and a lower side end connected to an edge of the base portion and includes an elastic band having elasticity and inelastic bands having relatively lower elasticity or no elasticity. Therefore, subsidence of the spinal cage into vertebrae can be suppressed.
Claims10
A spinal cage comprising:
- a bone support portion configured to be disposed between a first vertebra at an upper side and a second vertebra at a lower side, which neighbor each other, to support the first vertebra;
- a base portion positioned at a lower side of the bone support portion and configured to be disposed between the first vertebra and the second vertebra to come in contact with the second vertebra;
- and
- a sidewall portion including an upper side end connected to an edge of the bone support portion, a lower side end connected to an edge of the base portion to support the bone support portion relative to the base portion, an elastic band having elasticity, and inelastic bands having lower elasticity than the elastic band or no elasticity.
A spinal cage comprising:
- a bone support portion configured to be disposed between a first vertebra at an upper side and a second vertebra at a lower side, which neighbor each other, to support the first vertebra;
- a base portion positioned at a lower side of the bone support portion and configured to be disposed between the first vertebra and the second vertebra to come in contact with the second vertebra;
- and
- a sidewall portion which includes a plurality of elastic bands and inelastic bands alternately arranged with each other in a vertical direction between the bone support portion and the base portion, wherein the elastic bands have elasticity, and the inelastic bands have lower elasticity than the elastic bands or no elasticity.
