IntroductionThe bony pelvis consists of the two hip bones, the sacrum and the coccyx. The bony pelvis is divided into the greater pelvis and the lesser pelvis. The junction between the greater and the lesser pelvis is the pelvic inlet. The transverse and anteroposterior dimensions of the pelvic inlet will classify the pelvis as the anthropoid, gynaecoid, android, and platypelloid pelvis. Knowledge of female pelvis type is important for obstetricians to know the process of labour which can decrease the morbidity and mortality of mothers and neonates. Thus, the aim of this study was to find out the prevalence of gynaecoid pelvis among female patients attending the Department of Radiology of a tertiary care centre.MethodsThis was a descriptive cross-sectional study conducted in the Department of Radiology of a tertiary care centre from 24 July 2022 to 15 November 2022 after approval from the Institutional review committee (Reference number: 11/022). The study included radiographs of the female pelvis without any bony pathology and developmental anomalies. Anteroposterior and transverse dimensions of the pelvic inlet were measured using a digital ruler in a computer. A convenience sampling method was done. Point estimate and 95% confidence interval were calculated.ResultsAmong total female patients, the gynaecoid pelvis was found in 28 (46.66%) (34.04-59.28, 95% Confidence Interval). Mean anteroposterior and transverse diameters for the gynaecoid pelvis were observed to be 12.85±1.0 cm and 13.66±1.07 cm respectively.ConclusionsThe prevalence of gynaecoid pelvis was similar to the other similar studies conducted in similar settings.Keywordsfemale; pelvis; radiology.
