Sternal segment dislocation is rare in children, with only several cases reported in the literature. We present a case of sternal segment dislocation in a six-year-old boy. He was initially treated with closed reduction, however, complete re-dislocation occurred a week later. Although rotation of the dislocated segment was 58°, the segment was stable with sonography. Then, he was treated conservatively. A year after the injury, remodeling of the dislocated segment was achieved.

Acetabular dysplasia describes an underdeveloped or shallow, upwardly sloping acetabulum, which may occur with varying degrees of deformity of the proximal femur such as excessive femoral neck anteversion, coxa valga or femoral neck cam deformity. Numerous stabilising procedures have been described, one of the first being the shelf acetabuloplasty. Shelf procedure improves coverage of the femoral head, without changing orientation of the acetabulum.This will improve the range of movement in the hip and protect the femoral head. In this study, we investigated the effect of shelf acetabuloplasty for load distribution of acetabular roof and femoral head using the finite element method (FEM). A three-dimensional (3D) generic musculoskeletal model was developed based on computed tomographic (CT) to estimate joint reaction force. As a result, we funded load distribution decreased on the top of the ace tabular rim and femoral head. Shelf acetabuloplasty may effective procedure for acetabular dysplasia because of improvement for load distribution.
