修徳修 徳永俊福俊 福島宇薛宇孝 薛

Key Points

  • The aim is to report cases of intramedullary nail fractures following surgery for femoral metastatic bone tumors.
  • Case report of three women with femoral metastatic bone tumors and subsequent fractures.
  • Surgical interventions involved bone fixation and monitoring for complications over time.
  • Reoperations were performed using tumor prosthetic replacements in all cases.
  • Intramedullary nails fractured in all three patients at various post-operative intervals.
  • Complications included delayed bone union and pathological fractures after surgery.
  • All patients successfully underwent reoperation with tumor prosthetic replacement.

Abstract

【はじめに】大腿骨転移性骨腫瘍に骨接合術を行った後,髄内釘の折損による再手術を要した3症例を報告する.【症例】症例1:57歳女性,腰椎未分化多形肉腫.右大腿骨転移性骨腫瘍,転子部造骨性転移,切迫骨折に予防的内固定を行った.術後501日で右大腿骨頚部骨折を生じ,術後554日で髄内釘が折損した.症例2:70歳女性,肺癌,右大腿骨転移性骨腫瘍,転子下溶骨性転移による病的骨折に骨接合術を行った.骨癒合が遷延し,術後194日で髄内釘の折損と骨折部の再転位を生じた.症例3:49歳女性,乳癌,左大腿骨転移性骨腫瘍,転子部溶骨性転移,切迫骨折に骨接合術を行った.術後208日で病的骨折を生じ,236日で髄内釘が折損した.全例で腫瘍用人工骨頭置換術による再手術を行った.【考察】大腿骨転移性骨腫瘍に対する髄内釘固定は折損に注意する必要があるが,腫瘍用人工骨頭による再手術は可能であり,有用と考えられた.
