Key Points

The case aims to discuss complications like intra-medullary nail fracture after surgical repair of atypical femoral fractures.
Conducted surgical fixation with an intra-medullary nail two days post-injury.
Monitored complications three months post-operation including nail fracture and pseudarthrosis.
Performed a revision surgery to replace the intra-medullary nail.
Post-surgical complications included intra-medullary nail fracture, pseudarthrosis, and re-fracture.
Partial weight-bearing began six weeks post-surgery, progressing to full weight-bearing by eight weeks.
Bone union was achieved 1.5 years later with the patient able to walk independently.

Abstract

【症例】48歳女性．誘因なく礫音とともに左大腿部痛が出現し，体動困難となり当院へ救急搬送された．左大腿骨転子下骨折の診断で受傷後2日目に髄内釘による観血的整復固定術を施行した．内側に軽度のギャップと，3°の内反変形を残した．術後翌日より疼痛に応じて荷重を開始した．術後3ヵ月に近位スクリュー部での髄内釘折損，偽関節，転子下での再骨折を認めたため，髄内釘を入れ替えし，再手術を行った．術後6週より部分荷重を開始し，術後8週で全荷重を許可した．術後1.5年経過後は骨癒合を認め，愁訴なく独歩可能となっている．非定型大腿骨転子下骨折の解剖学的整復は困難と言われているが，内反転位は偽関節・インプラント破損の原因となり，本症例でも厳密な整復が必要であったと考えられた．
