Acetabular protrusion secondary to Austin Moore hemiar thoroplasty a long term study

ABSTRACT

Thirty-eight cases of Austin Moore hemiarthroplasty were reviewed for reporting acetabular protrusion. The mean age was 59 years and that of follow-up was 5.7 years. The acetabular score varied from 30 to 96 with a mean of 78.4 points. Protrusion was present in 23 cases, being most common in the age group 40-50 years, more in males than females, and increased with longer periods of follow-up. Osteoporosis, obesity and chronic medical condition have no significant effect on protrusion. The most significant factor was the level of the patient's activity after operation
