Background To assess particular features of fetal extremities evaluation using three‐dimensional ultrasound. Methods Total of 276 patients were selected from our routine outpatient clinic or sent for supervision from other clinics because of a suspected fetal anomaly. Patients were examined during a three year period (Jan1997‐Dec1999). Pre‐selected patients were examined with standard 2‐D ultasonic devices, and their gestation age ranged between 12 and 40 weeks. 3‐D ultrasound devices were Combison 530D and Voluson 530D MT (Kretztechnik, Zipf, Austria) with a 3–5 MHz annular array transducer for three dimensional volume scanning. Results In 28/276 patients the initial diagnosis was suspected by 2‐D sonography at entry in the study. In 18/28 suspected cases diagnosis was determined after examination by 3‐D sonography (15/28 clubfoot, 3/28 other limb anomalies). The diagnosis of clubfoot was confirmed In 17/28 cases after delivery or termination of pregnancy, meaning that 2/18 cases of clubfoot were not detected using ultrasonography. In all of 3 other cases the sonographic diagnoses of hand contractures and micromelia were confirmed after termination of pregnancy. Conclusion 3‐D sonography accurately visualized angular and structural limb anomalies. In two cases of severe oligohydramnios we missed clubfoot by 3‐D sonography.
