SUMMARY To evaluate the incidence and pattern of menstrual dysfunction in reproductive age group women suffering acute musculoskeletal trauma, 198 women between 15 and 50 years of age admitted consecutively into an acute orthopaedic unit were recruited over a 6‐month period. The patients were then followed up for 6 months with menstrual diaries to compare their menstrual pattern with their preadmission status. Excluding those with significant menstrual problems before admission, the menstrual pattern remained normal in 135 (68%) (EM), while 12 (6%) developed polymenorrhoea (PM), and 51 (25%) had oligomenorrhoea or amenorrhoea (OAM) within the 6‐month observation. The three groups did not differ in their mean age, body mass index, parity or age of menarche, but previous cycle lengths were shortest in the PM group (25.4 days, SD 7.64) (p<0.05) and history of amenorrhoea in the previous one year was most common in the OAM group (p<0.025). Univariate analysis showed the incidence of moderate to major trauma, operative treatment, longer operative time, general anaesthesia, blood transfusion and immobilisation were significantly higher in the PM and OAM groups compared to the unchanged group (p<0.05). A logistic regression model showed that general anaesthesia and longer surgical operations remained significantly related to the development of menstrual dysfunction. We conclude that the pattern of menstrual dysfunction after acute orthopaedic trauma appeared to be dictated by the woman's pre‐existing menstrual characteristics and the stress of surgical treatment.
