Purpose: Evaluation of the incidence of a midline sternal foramen, as a developmental anomaly, in order to avoid fatal complications following sternal puncture of sternal acupuncture treatment.
Material and methods: 100 chest computed tomograms were evaluated in reference to the incidence of this anomaly and its various features.
Results: The variety of CT aspects ranged from very incomplete types with only sandglass-like retraction of sternal cortex, to a complete foraminal defect. The incidence of midline sternal foramen in a feature bearing a risk of complication, is approximately 6%.
Conclusion: We conclude that--if sternal acupuncture is planned in the region of corpus--previous radiographs should be done to rule out this anomaly. Furthermore, we strongly recommend the acupuncture technique of the "Wiener Schule", which prescribes a safe superficial-oblique approach to the sternum.
