Abstract
Redislocation of bipolar hemiarthroplasty is not a simple complication. When redislocation of bipolar hemiarthroplasty occurs, open reduction must be considered. Displacement of the polished tapered femoral stem could occur through the unwanted traction force during the reduction of the dislocated cemented hip arthroplasty as a complication. We experienced displacement of the polished tapered femoral stem during closed reduction of a redislocated cemented bipolar hemiarthroplasty. We suggest that preoperative analysis for the cause and status of the dislocation is essential and open reduction should be considered if closed reduction is not thought to be suitable for a polished femoral stem.
Figures and Tables
Fig. 1
Preoperative anteroposterior radiograph of both hips of a 72 year old female showed a displaced right femoral neck fracture.
Fig. 2
Immediate postoperative radiograph revealed the cemented bipolar hemiarthroplasty with excessive cement filling distal to the tip of the stem.
Fig. 3
This radiograph obtained at postoperative 6th day showed dislocation of the bipolar hemiarthroplasty with flexion and adduction of the right hip.
Fig. 4
AP radiograph at postoperative 9th day revealed redislocation of the right hip three days after the first dislocation.
Fig. 5
This radiograph showed proximal displacement of the femoral stem after the trial of closed reduction.
