Abstract

The Michaelis rhombus is a kite-shaped area in the lower back that surrounds the lower lumbar spine and sacrum. It is accessible and easy to measure. Measurement of Michaelis Rhombus is an easy clinical method for assessment of pelvis in antenatal women. This rhombus can be a predictor of CPD. Aim and Objective: The present study was conducted to evaluate the dimensions of the Michaelis rhombus as predictor of contracted pelvis and its efficacy for pelvic assessment of antenatal mothers. Method: This is a Prospective Observational comparative study conducted on 220 antenatal pregnant women who were admitted at the Department of Obstetrics and Gynaecology, R. D. Gardi Medical college and C.R.G. Hospital, Surasa, Ujjain (M.P.), India from November 2020 to May 2022. This study was carried out on pregnant women in the age group of 19-35 years, which were coming for delivery in our hospital with gestational age >36 weeks. Result: Out of 220 subjects 190 delivered by normal delivery and 30 subjects by LSCS. Transverse diagonal was significantly lower in LSCS cases with mean 9.53±0.69 cm as compared to normal delivery where transverse diagonal was, with mean 10.59±0.55 cm (p = 0.000). Vertical diagonal was significantly lower in LSCS cases with mean 10.73±0.87 cm as compare to normal delivery where vertical diagonal was, with mean 11.94±0.73 cm. Conclusion: Michaelis rhombus can be used as predictor of contracted pelvis. Michaelis rhombus measurement help to increase ease of patient for clinical assessment of pelvis by less number of per vaginal examination, so that there is less risk of infection. Training of ANM and primary health care worker to measure the Michaelis rhombus would be easy and indirect pelvic assessment could be done, without risk of pelvic examination.
