Lateral Humeral Condyle Fracture in Childhood: Results of a New Surgical Technique.

Fractures of the lateral condyle of the humerus are one of the most common fractures in children, accounting for between 10% and 20% of fractures involving the elbow, with a peak incidence at 6 years of age. Treatment is often surgical for displaced fractures > 2 mm, according to Milch and Jakob classification. There is no consensus in the literature about the appropriate surgical management of these fractures.

Elastic Antiproton-Nucleus Scattering from Chiral Forces.

Elastic scattering of antiprotons off ^{4}He, ^{12}C, and ^{16,18}O is described for the first time with a consistent microscopic approach based on the calculation of an optical potential (OP) describing the antiproton-target interaction. The OP is derived using the recent antiproton-nucleon (p[over ¯]N) chiral interaction to calculate the p[over ¯]N t matrix, while the target densities are computed with the ab initio no-core shell model using chiral interactions as well. Our results are in good agreement with the existing experimental data and the results computed at different chiral orders of the p[over ¯]N interaction display a well-defined convergence pattern.
