The objective of the study was to assess clinical-X-ray endpoint on a cohort of 48 patients (54 hips) submitted to Spotorno® primary non-cemented total hip arthroplasty in the last 20 years (1985 - 2005), with mean follow-up time of 17.5 years (range: 8-20 years). In the clinical and functional evaluation, 92.7% good outcomes were achieved. Osteopenia was found in 24 acetabula (44.4%) and 30 femurs (55.6%); A mean of 2 millimeters (0-5 mm) of polyethylene wear-off was present in 43 acetabula (79.6%). The statistical analysis of the results suggested that the presence of osteopenia is not associated to the clinical endpoint (p=0.75); polyethylene wear-off as well as the presence of osteopenia was more significant if patients below the age of 55 years (p<0.05). We concluded that the use of a Spotorno® prosthesis on this cohort showed god outcomes, similar to those previously reported in literature.
