Abstract

Objective. To determine the incidence of clavicular fractures, associated fetal and maternal risk factors and its connection with quality care control. Subjects and methods. A total of 3030 newborns delivered vaginally were evaluated for clavicular fractures by three separate physicians. The study group included all newborns with fractured clavicle. A control group consisted of 52 newborns delivered vaginallly with no history of fractures. Maternal records were evaluated for possible predisposing factors. Results. Forty-six (1.5%) newborns were found to have clavicular fractures. When compared to the control group, they were found to have a higher birthweight (3710 ± 352 gm vs 3235 ± 405 gm) an older maternal age (30.5 ± 5 vs 27.7 ± 6), a longer second stage of labor (34 min vs 23 min), higher rate of instrumental deliveries (13/46 vs 6/52) and shoulder dystocia (6/46 vs 1/52). Nearly 80% of newborns with clavicular fractures weighed less than 4000 gm. Multivariate analysis demonstrated two independent variables; birthweight over 3500 gm and maternal age > 29. Conclusion. Clavicular fractures are associated with higher birthweight, older maternal age, longer second stage of labor, instrumental deliveries and shoulder dystocia. However, in most cases this injury cannot be predicted prior to delivery and thus cannot be an indicator of quality control.
