A helical blade type of hip screw is used widely for the operative management of femoral trochanteric fractures. A 73-year-old femalepatient was admitted for femoral trochanteric fracture AO/OTA type 31A2.2. A helical blade locking sleeve dissembled 18 weeks after surgery did not achieve accurate reduction. The patient underwent bipolar hiphemiarthroplasty because the fracture reduction was lost, and it was impossible to remove the remaining helical blade without bone loss. The authors report this case of a rare complication of helical blade.
