Hip Arthroplasty for Treatment of Atypical Femoral Fracture with Pre-existing Hip Osteoarthritis: 用全髖關節置換術來治療同時患有髖骨關節炎和非典型股骨骨折的病人：病例報告

A 72-year-old woman with bilateral hip dysplasia sustained atypical femoral fracture of the left subtrochanteric region. She underwent left total hip replacement with a long extensively porous coated femoral stem. The fracture healed with incorporation of the strut allograft after 8 months. A painful horizontal radiolucent line at the tip of the femoral stem was noted after 4 years, with resolution of symptoms after a period of protected weight bearing. We believe that total hip replacement for subtrochanteric atypical femoral fracture with pre-existing hip dysplasia is a feasible option and avoids a second operation for the treatment of osteoarthritis.

中 文 摘 要案例一位72歲的女病人，本身患有雙側髖關節發育不良，遭受左股骨粗隆下非典型股骨骨折。她接受了左全髖關節置換術，並放置了全孔洞覆蓋式股骨長柄假體。骨折後8個月，骨折成功和結構性異位骨癒合。手術後4年，病人出現疼痛，並在股骨長柄假體末端出現了一條疑見透亮線影。症狀在使用保護性負重一段時間後，得以消除。結論我們相信，利用全髖關節置換術來治療同時患有非典型股骨骨折和髖關節發育不良的病人，是一種可行的選擇，並且可以避免進行第二次手術來治療骨關節炎。
