Abstract

Purpose: To evaluate the long-term outcome of fetuses with a diagnosis of isolated short long bones. Methods: A retrospective review was conducted of all cases diagnosed with short long bones above 20 weeks of gestation during 2010–2017 in a single tertiary center. Exclusion criteria included abnormal sonographic findings other than short long bones, suspected genetic syndromes, chromosomal abnormalities, and abnormal Doppler flow indices. Follow-up was carried out by telephone questionnaire. Results: During the study period, 54 (24.32%) women met inclusion criteria. Mean gestational age at delivery was 38.05 years (± 2.42 SD). Mean birth weight was 12–19th percentile according to the local fetal growth charts [2645 g (± 684 SD) 95% CI 2173–2980]. Median time for post-natal follow-up was 9.3 years (IQR 6.6–10.75). Growth below the 10th percentile was demonstrated in 27 (50%) children. 11 (20.37%) children were followed up by endocrinological clinics, of them 7 (12.96%) were treated with growth hormone. Three (5.6%) of the children were diagnosed with attention deficit hyperactivity disorder, an incidence that is considered lower than that of the general population (± 9%). Conclusions: Prenatal fetal isolated short long bones diagnosed during the late second and third trimester is associated with short stature. No neurodevelopmental impact was observed in our study group.
