Dissociation Between Polyethylene and Inner Prosthetic Ball Head During Closed Reduction of a Dislocated Bipolar Hip Hemiarthroplasty: A Report of 3 Cases / 대한정형외과학회잡지

ABSTRACT

Closed reduction of a dislocated bipolar hemiarthroplasty may induce dissociation between polyethylene and inner prosthetic ball head. This rare complication should be treated by open reduction. If dislocation of the bipolar hemiarthroplasty occurs, gentle closed reduction techniques with satisfactory anesthesia and muscle relaxation are recommended. We report our experience of 3 cases.
