    Osteogenesis imperfecta (OI) is commonly associated with fragility fractures. It is due to abnormality in the quantity and quality of collagen type 1 caused by mutations in COL1A1 and COL1A2 genes. Patients with OI would also have blue sclera, ligament hyperlaxity, dentinogenesis imperfecta, hearing abnormality, and short stature. Surgical management is preferred to conservative treatment in long bone fractures. For malunited fractures, Sofield-Millar or multiple osteotomies at different sites of deformities are performed with additional intramedullary device to stabilize the bone. This is a case of femur fracture with multilevel CORAs in an adolescent patient with post-trauma OI in which z-osteotomies were performed and stabilized with titanium elastic nails resulting in good outcomes clinically and radiologically.

    The title compound, C6H2N3O7 -·C10H13Cl2N2 +, crystallizes with one 1-(2,3-di-chloro-phen-yl)piperazine (DP) cation and one picrate (PA) anion in the asymmetric unit. In the crystal structure, the DP cation and PA anion are inter-connected via several N-H⋯O and C-H⋯O hydrogen bonds. The DP cation and PA anion are further connected through C-Cl⋯π [3.8201 (4), 3.7785 (4) Å] and N-O⋯π [3.7814 (4) Å] inter-actions. The DP cations are further inter-connected via a weak inter-molecular Cl⋯Cl [3.2613 (4) Å] halogen-halogen inter-action. The combination of these supra-molecular inter-actions leads to a herringbone like supra-molecular architecture.

    In the title 2:1 co-crystal, 2C4H5ClN4·C4H6O4 the complete succinic acid mol-ecule is generated by a crystallographic centre of symmetry. In the crystal, pairwise O-H⋯N and N-H⋯O hydrogen bonds link the pyrimidine and succinic acid mol-ecules, generating R 2 2(8) loops. The pyrimidine mol-ecules are linked by pairwise N-H⋯N hydrogen bonds, again generating R 2 2(8) loops. Collectively, the hydrogen bonds link the components into corrugated (100) sheets. The Hirshfeld surface is presented.
