Abstract
Description
以下の議論は第1の端板14に関するが、第2の端板16が本発明の実施形態において第1の端板14と実質的に同一であるので、それが第2の端板16にも同様にあてはまることが理解されるべきである。図40〜45を参照して、例示的な実施形態では、第1の端板14は、第1の端39及び第2の端41を有する。図示される実施形態では、第1の端板14は、第1の端39と第2の端41とを接続する上部面40、及び第1の端39と第2の端41とを接続する下部面42をさらに備える。図示しないが、実施形態では、第1の端板14は貫通開口部をさらに備え得る。貫通開口部は、例示的な実施形態では、骨移植または類似した骨の成長誘導材料受容するようにサイズ決めされる。
