RESUMO
OBJECTIVE: To show the results of the study on the Mayo femoral stem during its first ten years of use in Mexico. MATERIAL: Forty-two bone sparing Mayo femoral stems were studied; they were placed in 39 patients from July 2000 to March 2009, ages 24-71 years (mean 51.6 years), with a mean follow-up of 61 months. METHODS: The clinical results of 42 arthroplasties performed by 3 surgeons were assessed using the Merle D'Aubigné scale; a radiologic assessment was made and the findings and complications were described. RESULTS: No stem-related complications were found in this study. There was one case of revision due to recurrent dislocation, secondary to poor placement of the acetabulum. No cases of clinical or radiologic loosening were reported. CONCLUSIONS: Conservative hip arthroplasty with the Mayo stem has proven to be an excellent medium- and long-term option for femoral hip replacement, with expectations that it may exceed the durability of other types of implants without harming the femoral diaphysis. This may facilitate eventual stem revision and give us the opportunity of using a standard primary implant.
