Abstract
AIMS: To highlight a case of recurrent atraumatic anterior hip dislocation management using a dual mobility prothesis. METHODS: The stability of the patient's hip was assessed using X-ray and MRI scans. Upon the third spontaneous anterior dislocation it was decided with the patient's consent to undergo a total hip replacement. A piriformis sparing anterior approach was use with the insertion of a dual mobility bearing. This consisted of an uncemented porous titanium cup articulating with a 28 mm head in a 42 mm mobile polyethylene liner. RESULTS: Mobilising pain free at 6 weeks post operation with no further dislocations at 6 months follow up. CONCLUSION: Dual mobility hip replacements was used successfully in our patient with recurrent atraumatic anterior hip dislocation.
