Pediatric Sternal Segment Dislocation Caused by Different Types of Injury: A Report of Two Cases

Sternal segment dislocations in children are extremely rare, and there is currently no consensus on their mechanism of injury or management approach. We report two pediatric cases of sternal segment dislocation with different mechanisms of injury. Case 1, a four-year-old girl, sustained an injury without any direct impact or bruising. Radiographic examination revealed dislocation of the first sternal segment with anterior displacement of the sternal body. Case 2, a seven-year-old boy, developed chest pain after striking his chest against the edge of a desk. Imaging showed no anterior displacement of the sternal body relative to the manubrium. Both cases were treated conservatively, resulting in spontaneous bone remodeling and favorable outcomes, despite surgical management being more commonly reported in the literature. Careful consideration is warranted when determining treatment strategies for young patients with significant potential for bone remodeling.
