UNUSUAL NECK OF FEMUR FRACTURE AFTER TOTAL HIP REPLACEMENT- A
CASE REPORT

Queen Elizabeth Hospital, Newcastle (UNITED KINGDOM)
We present an unusual case of fracture at the neck of the implant following a total hip
replacement. A 72 year old gentleman underwent cemented total hip replacement for
primary osteoarthritis of the hip. The post operative period was uneventful and he
was mobilising well without any post operative complications of infection or
dislocation. He presented to accident and emergency following a mechanical fall from
a standing height on to his hip and inability to mobilise two years following the hip
replacement. Clinical examination revealed a tender hip, with the leg shortened,
flexed, abducted and externally rotated. He had no distal neurovascular deficits. All
movements of the hip were restricted with pain. Radiographs revealed a fracture
through the neck of the femoral stem in a cemented THR. The components were well
cemented with no evidence of loosening. He underwent a revision total hip
replacement. We performed an extended trochanteric osteotomy to remove cement
and extract the broken implant. He was revised to a longer stem with secondary
stabilisation with cables. He recovered uneventfully following the operation and was
mobilising independant when he was discharged from the hospital.This case
highlights the need for awareness of the possibility of a broken implant following
THR.
