Description
少なくとも2個の脊椎骨をお互いの空間的関係で維持する方法には以下の順序を指示するステップも含められる:締結材を締結材用穴58に挿入する。例えば、一実施例では、骨加圧装置40には4個の締結材用穴58(図4−7)が含まれている。第一の端部51の近くの第一の締結材用穴58、101(図5及び7の左上)は、第二の端部52の近くの第四の締結材用穴58、104(図5及び7の右下)に対して対角線に配置されている。又、第一の端部51の近くの第二の締結材用穴58、102(図5及び7の右上)は、第二の端部52の近くの第三の締結材用穴58、103(図5及び7の左下)に対して対角線に配置されている。そして、第一の締結材を第一の締結材用穴58、101に挿入する。そして、プレート50の第一の端部51を骨(少なくとも1個ある脊椎骨のうちの1個)に固定する。次ぎに、第二の締結材を第四の締結材用穴58、104に挿入し、プレート50の第二の端部52を骨(少なくとも1個ある脊椎骨のうちの1個)に固定する。次ぎに、第三の締結材を第二の締結材用穴58に挿入することにより、プレート50の第一の端部51を骨(少なくとも2個ある脊椎骨のうちの1個)に固定する。又、第四の締結材を第三の締結材用穴58、103に挿入することにより、プレート50の第二の端部52を骨(少なくとも2個ある脊椎骨のうちの1個)に固定する。この方法で、締結材を締結材用穴58に挿入して、プレート50を骨に固定することによりねじり抵抗が低減し、それにより、骨加圧装置40が時間と共にゆるまない可能性が高まる。
Claims (23)
