Abstract
There is controversy regarding the optimum method of stabilising traumatic anterior pelvic ring injuries. This study aimed to evaluate the role of pubic symphysis plating.
Methods
All patients who underwent pubic symphysis plating in a regional pelvic and acetabular unit were studied. Fracture classification, type of fixation, complications, and incidence of metalwork failure were recorded.
Results
Out of 178 consecutive patients, 159 (89%) were studied for a mean of 37.6 months. There were 121 males and 38 females (mean age 43 years). Symphysis pubic fixation was performed in 100 AO-OTA type B and 59 type C injuries using a Matta symphyseal plate (n=92), reconstruction plate (n=65), or DCP (n=2). Supplementary posterior pelvic fixation was performed in 102 patients. 5 patients required revision for failure of fixation or symptomatic instability of the pubic symphysis. A further 7 patients had metalwork removed for other reasons. Metalwork breakage occurred in 63 patients (40%). 62 of these 63 patients were asymptomatic and metalwork was left in situ.
Conclusions
Plate fixation of the symphysis pubis is an effective method of stabilising anterior pelvic ring injuries with a low complication rate. There is a high rate of late metalwork breakage, but this is not clinically significant.
