[Early experiences in the use of Mayo stem in hip arthroplasty].
The aim of this study was early clinical and radiological examination of patients after THR with Mayo stem. In the years 2004-2007 at Orthopaedic and Traumatology Department, Medical University in Lublin 38 Mayo stems were implanted in 35 patients. There were: 5 women and 30 men in the age from 27 to 67 years (average 51 years). The main cause of surgery was primary coxarthritis in 17 hips, AVN in 17, and DDH in 4. Follow-up is from 12 to 48 months (average 24.2 months). Preoperative Harris Hip Score varied from 32 to 45 pts. (average 38 pts.) and increased to 75-100 pts. (average 96 pts.) at longest postoperative follow up. There was one postoperative dislocation of THR 3 weeks after the surgery. There was one Mayo stem migration nine months after the surgery (15 mm) with radiolucent lines in all Gruen's zones. Conclusions. 1) Operative technique of Mayo stem is easy even with minimalny invasive technique. 2) The use of metal on metal bearing surfaces with short metaphyseal stem in THR gives possibility for good durable clinical result
