Cleft sternum and sternal foramen
1Heineman Medical Research Laboratories, Carolinas Medical Center, Charlotte, North Carolina, USA.
Insights
Cleft sternum, a rare congenital defect, leaves the heart unprotected and requires neonatal surgical correction for optimal outcomes. Awareness of sternal foramen is crucial for patient safety during procedures like acupuncture.
Area of Science:
- Pediatric Surgery
- Congenital Malformations
- Thoracic Surgery
Background:
- Cleft sternum is a rare congenital anterior chest wall defect resulting from failed midline sternal fusion.
- It presents as complete or incomplete forms, leaving the heart and great vessels vulnerable.
- Commonly associated with craniofacial hemangiomas and omphalocele.
Purpose of the Study:
- To review the diagnosis and surgical management of cleft sternum.
- To highlight the importance of timely intervention and potential complications.
- To discuss sternal foramen as a related anomaly.
Main Methods:
- Review of congenital sternal defects, focusing on cleft sternum.
- Discussion of diagnostic modalities including ultrasonography and CT scanning.
- Analysis of surgical techniques for neonatal and delayed repair.
Main Results:
- Prenatal diagnosis of cleft sternum is feasible via ultrasonography.
- Neonatal surgical correction offers the best outcomes; delayed repair may require advanced techniques.
- Sternal foramen is an asymptomatic defect detectable by CT, posing risks during acupuncture.
Conclusions:
- Early surgical intervention in the neonatal period is crucial for cleft sternum repair.
- Surgical techniques are available for delayed repair, though more complex.
- Understanding these sternal anomalies is vital for clinical practice and patient safety.
Abstract:
Cleft sternum is a rare congenital defect of the anterior chest wall and is the result of a failed midline fusion of the sternum. Depending on the degree of separation, there are complete and incomplete forms. Its clinical significance is that it leaves the heart and great vessels unprotected. Association with craniofacial hemangiomas and omphalocele is common. Prenatal diagnosis by ultrasonography is possible. Surgical correction should be performed during the neonatal period when the direct suturing of the sternal halves is possible and the thorax can accommodate the thoracic viscera. At an older age, surgical repair is feasible, but it may require additional measures, such as sliding chondrotomies of the adjacent costal cartilages and notching of the sternal bars, to facilitate the approximation. Lung herniation at the base of the neck should be corrected by uniting the cervical muscles. The first postoperative day is the most critical because of acute reduction of the mediastinal space. Long-term results are satisfactory. Sternal foramen is a congenital oval defect at the lower third of the sternum that is asymptomatic and could be detected by CT scanning. The awareness of the anomaly is important in acupuncture practice because of the danger of heart damage.

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid process.
