Completed

• Conditions: Osteoarthritis; Femoral Neck Fracture

• Registration Number: NCT01644227
• Lead Sponsor: Sundsvall Hospital

Brief Summary

Retrospectively study reviewing 34 patients operated with dual mobility cups in total hip arthroplasty between January 2009 and June 2012 at Sundsvall Hospital.
