Study finds, Comparison of Patient Demographics and Patient-
In the proper age group, there is evidence that total hip arthroplasty (THA) has superior outcomes for the treatment of acetabular fractures compared with open reduction and internal fixation. The purpose of this study was to (1) compare baseline demographics of patients who did and did not develop infections and (2) identify risk factors associated with developing either SSIs or PJIs.

The inclusion criteria consisted of patients sustaining an acetabular fracture and treated with THA who developed either SSIs or PJIs within 90 days or 2 years, respectively, whereas patients not developing infections served as control subjects. Baseline demographics were compared. A multivariate regression model calculated the odds ratio (OR) associated with development of infections.

--The study demonstrated significant differences among the cohorts regarding baseline demographics.

--The greatest risk factors for SSIs within 90 days were morbid obesity, pathologic weight loss, and iron deficiency anemia.

--An increased risk of PJIs was associated with iron deficiency anemia, pathologic weight loss, and morbid obesity.

Conclusively, This study found notable differences between baseline demographics of the cohorts and a myriad of risk factors associated with developing infections after THA for acetabular fractures.
