OBJECTIVE:: The purpose of this study was to compare various gender and ethnic groups to characterize differences in baseline version and rates of retroversion. DESIGN:: Retrospective SETTING:: Level 1 trauma center PATIENTS/PARTICIPANTS:: Between 2000 and 2009, 417 consecutive patients with femur fractures were treated with an IM nail at Level I trauma and tertiary referral center. Of these, 328 with computed tomography (CT) scanogram of the normal, uninjured contralateral femur were included in this study. MAIN OUTCOME MEASUREMENTS:: Femoral version RESULTS:: The mean alignment for all patients was 8.84±9.66 degrees of anteversion. There were no statistically significant differences in mean version between African-American, Caucasian, and Hispanic patients for males or females. While there were also no significant differences in rates between ethnicities, retroversion was found to be common in Caucasian males (21.4%), African-American males (15.1%), and all groups of females (>14.3%). Furthermore, nearly 6% of both African-American males and females exhibited greater than 10 degrees retroversion. CONCLUSIONS:: While there may not be a significant difference in average femoral version between ethnic and gender groups, retroversion is relatively common, and retroversion greater than 10 degrees was observed in nearly 6% of the African-American population. This may have important implications in proper alignment restoration and successful clinical outcomes following IM nailing of femur fractures. LEVEL OF EVIDENCE:: Level III: retrospective case controlled. |
