The ideal bearing surface for total hip arthroplasty is still an area of debate.Increasing numbers of total hip replacements are being done in the younger patient population.Ceramic-on-ceramic bearings have gained popularity due to their low wear rate.However, ceramic fractures with subsequent catastrophic failures have been reported. This study reports on early results of ceramic-on-ceramic total hip replacements.

This is a study analyzing a prospectively collected data for seventy-five ceramic-on-ceramic total hip replacements with minimum follow up of eighteen months. Average age at time of surgery was forty-seven years. This study focused on the complications of this ceramic population. Complications included: One posterior dislocation, two intra-operative calcar fractures that needed wiring, one intra-operative fracture of the acetabular liner, two cases of impingement (one which resulted in a revision), and one periprosthetic fracture. The two patients that required further surgery were the periprosthetic fracture after a fall and one for component impingement. No revisions were performed for loosening or catastrophic failures. No wear, loosening, or osteolysis was seen on radiographs. The SF-12, WOMAC, and Harris Hip scores were not significantly different from other reported hip series.

Ceramic-on-ceramic bearing surfaces in total hip arthroplasty are a safe option with outcome equivalent to standard THR in the short term. Ceramic Hips may provide a more durable prosthesis, especially in young and active patients. Intra-operative technical guidelines that may enhance the quality of the results will be presented and fully disclosed.
