Pseudotumor formation and serum ions after large head metal-on-metal stemmed THR
The objective of this study was to identify the true incidence and risk factors of pseudotumor formation in large head metal-on-metal total hip arthroplasties. Incidence, time course and risk factors for pseudotumor formation were analysed. After median follow-up of 3 years, 706 hips were screened in 626 patients. There were 228 pseudotumors (32.3 %) in 219 patients (35.0 %). Pseudotumor formation significantly increased after prolonged follow-up.
This study confirms a high incidence of pseudotumors, dramatically increasing after prolonged follow-up. Read more here.
