Abstract：
A 78 year-old man fell 6 months after Sivash-range of motion (S-ROM) total hip arthroplasty (THA), after which he developed hip pain and external rotation deformity. Imaging showed stem malrotation in relative retroversion. Revision THA was delayed because of medical issues, occurring 1.5 years after the fall. No corrosion was observed intraoperatively at the stem-sleeve interface. His symptoms resolved after revision THA.
We present a rare complication of S-ROM THA-dissociation of the femoral stem from the proximal sleeve, with subsequent re-engagement in static malrotation. No corrosion was observed, suggesting that the stem had stably reseated within the sleeve.

摘要：
方法：一名78岁男子在Sivash-rangeofaction(S-ROM)全髋关节置换术(THA)后6个月跌倒，之后他出现了髋部疼痛和外旋畸形。影像学显示相对逆行时茎旋转不良。由于医疗问题，修订THA被推迟了，发生在跌倒后1.5年。术中在杆-套筒界面处没有观察到腐蚀。他的症状在修正THA后消失。
结论：我们提出了一种罕见的S-ROMTHA并发症-股骨干从近端套筒解离，随后在静态旋转不良中重新接合。没有观察到腐蚀,表明茎已稳定地重新插入套筒内。
