Abstract

A 59-year-old male, diagnosed with advanced arthritis of left hip underwent total hip arthroplasty using a modular dual mobility with metal liner. Post-operative radiographs there was suspicion of incomplete seating of the metal liner inferiorly. The patient was reoperated the next day which confirmed the incomplete seating. The metal liner seating was corrected which was confirmed by intra operative visualization and fluoroscopy. Post-operative radiographs showed complete seating of the liner. Periodic follow ups were uneventful. Incomplete seating of dual mobility metal liner especially at the inferior part, though seldom reported is a possible complication which can lead to early failure.
