OBJECTIVE: To elucidate whether there is a relationship between pregnancy-related pelvic pain and degree of symphyseal laxity. METHODS: Forty-nine women were interviewed and examined and ultrasonographic measurement of symphyseal width and vertical shift was conducted at 12 and 35 weeks of pregnancy and at 5 months post partum. The patients were retrospectively classified into four groups on the basis of presence and degree of pain in late pregnancy and presence or absence of pain at follow up. RESULTS: The prevalence of pelvic pain of any degree during pregnancy was 49%, of pronounced pain 16.3% and of severe pain 6.1%. Nineteen percent had any remaining pain at 5 months post partum. The median symphyseal width at 12 and 35 weeks of pregnancy and at 5 months post partum was 3.5 mm, 4.6 mm and 2.8 mm, the median vertical shift 0.0 mm, 0.8 and 0.9 mm respectively. Those with disabling pain during pregnancy and no pain at follow up had greater symphyseal width (6.3 mm) and vertical shift (1.8 mm) at 35 weeks of pregnancy than controls; 4.5 mm (p<0.01) and 0.5 mm (p<0.01) respectively. Those with disabling pain during pregnancy and persistent pain at follow up did not differ significantly from controls in symphyseal width or shift. The most severe cases were in this group. CONCLUSION: There is a minor pregnancy-induced physiological increase in laxity of the symphyseal soft tissue. There is no evidence that the degree of symphyseal distention determines the severity of pelvic pain in pregnancy or after childbirth.
