Dislocation following bipolar hemiarthroplasty is rare

Following bipolar hemiarthroplasty of the hip, dislocation is relatively rare and patients generally report an increased range of movement when compared to those who undergo unipolar arthroplasty.

Moreover, if complications do arise they can generally be treated with simple closed reduction.

However, according to new research published in Orthopaedics 2010, recurrent dislocation and cases which present cup dissociation should be treated with open reduction.

Looking at a single, 72-year-old patient, the surgeons behind the new paper said: "Forced closed reduction should not have been attempted after the second dislocation, as she was a candidate for open reduction.

"Furthermore, open reduction could have prevented the femoral stem displacement."

"To prevent such a situation, we suggest that... a polished tapered femoral stem is used during the primary surgical procedure," they added.

At the start of this year, research published in the European Journal of Bone and Joint Surgery noted that women under 40 are more likely to require revision following metal-on-metal hip resurfacing than their male counterparts.
