Description
ステップ1200において、外科医は、骨を近位部分と遠位部分とに分離するための骨切り術を行う。例えば、外科医は、第1中足骨を近位部分と遠位部分とに分離するために、横断骨切り術を行うことができる。(図12Cの残りの説明は、骨を足の第1中足骨とするが、これは限定されない例であり、前記方法は他の骨に適用され得る。)
ステップ1202において、外科医は、骨部分の1つを移動させ、遠位部分の最も近い内縁が第1長手方向の軸からずれる。例えば、外科医は、第1中足骨の近位部分の切断(前方)表面の少なくとも一部分を露出させるために、第1中足骨の遠位部分を側方向に動かすことができる。
図23乃至図25は、インプラント2300のまた別の例を示す。インプラント2300は、骨の遠位部分(例えば、中足骨)の内側偏位を矯正するために、側方向角度を矯正するよう構成される。図1のインプラント100と同様に、インプラント2300は、髄内部分の中央長手方向の軸からずれている髄外部分2330を含む。また、髄外部分2330は、側方向角度の矯正を行うために、図25に示している、(髄内部分2310の中央長手方向の軸2320に対する)オフセット角度θを有する。図23は、インプラント2300の外側図である。図24は、図23のインプラント2300の上面図である。図25は、断面線25−25に沿って取った図23のインプラント2300の断面図である。図30は、患者の足400に挿入された後のもとの位置のインプラント2300を示す概略図であり、さらに、図30は、インプラント2300上に重ねられたブローチ2600(点線)を示し、ブローチ2600は、インプラント2300を収容するための髄内孔を形成するのに使用される。
