BackgroundFailure of fixation (FF) in pubic symphysis diastasis (SD) ranges between 12 to 75%, though whether it influences functional outcomes is still debated. The objective of this study is to evaluate the impact of anterior pelvic plate failure and loss of reduction on Majeed's functional scores. MethodsSingle center retrospective review of consecutive patients with acute SD treated by means of anterior pubic plating. Thirty seven patients with a mean age 45.7+/-14.4 years, were included.

Majeed´s functional scores at minimum 6 months followup were compared according to the presence of FF and loss of reduction. ResultsFifteen patients presented FF. Eight presented an additional loss of symphyseal reduction. Mean Majeed´s score (MMS) in patients with and without FF was 64,4+/-13,04 and 81.8+/-15.65 respectively (p=0.0012). Differences in MMS in patients without FF and those with FF and maintained or loss of anterior reduction were 11,3 [70,5vs81,8] (p=0,092) and 22.7 [59,1vs81,8] (p=0,001) respectively. Significant association of FF with AO classification was noted. (OR 12.6; p=0.002).ConclusionsDifferences in MMS in the analysed groups suggest that loss of reduction might be more relevant than failure of the anterior osteosynthesis in functional outcomes.
