Abstract

Periprosthetic fracture of the femur is an uncommon complication after total hip arthroplasty (THA), but it appears to be increasing in incidence as a result of the aging population demographics and the increased number of THAs that are being performed. Much interest has been generated regarding low energy fractures in the elderly, but repeated periprosthetic fractures in the same femur are uncommon. The authors present here the case of a 71 year old patient who sustained repeated low energy ipsilateral periprosthetic femur fractures. The initial injury was caused by a road traffic accident, but the subsequent fractures were all caused by low energy falls. The patient sustained proximal and distal femur fractures with implants in situ. The probable causes of such fractures was a combination of systemic and local host factors, such as osteoporosis, cortical stress risers, local osteopenia secondary to bed rest, quiescent infection and altered fracture site vascularity due to the internal fixation devices and multiple re-operations.

고관절 전치환술 후에 대퇴골 삽입물 주위 골절은 드문 합병증이지만 고령 인구와 고관절 전치환술의 증가에 따라 증가하고 있다. 고령에서 저에너지에 의한 대퇴골 삽입물 골절에 대한 관심이 생기고 있으나 반복적인 대퇴 삽입물 주위 골절은 드물다. 본 저자들은 동측에 반복적인 저에너지의 대퇴 삽입물 주위 골절을 보인 71세 환자에 대해서 보고하고자 한다. 최초의 손상은 교통 사고에 의해 발생하였지만 연속된 골절은 저에너지에 의해서 발생하였으며, 대퇴 삽입물의 근위부와 원위부에 골절이 발생하였다. 이와 같은 골절은 골다공증, 피질골의 스트레스, 장기간의 침상요양에 의한 골감소증, 휴지기의 감염 및 수 차례의 재수술과 내 고정물로 인한 골절 부위의 변화된 혈액 순환 등의 복합적 원인에 의한 것으로 보인다.
