Ultrasound-guided clavipectoral fascial plane block (CPB) and intermediate cervical plexus block (ICPB) have been used as novel approaches for clavicular fracture surgery in adults. However, there are few reports of ultrasound-guided CPB combined with ICPB for clavicular surgery in children under 18 years of age. A 16-year-old male baseball player (weight, 57 kg; height, 160 cm) was scheduled to undergo open reduction and internal fixation with superior plate placement for a left-sided displaced midshaft clavicular fracture.

The liquid-phase reduction method for the preparation of metal nanoparticles (NPs) by the reduction of metal salts or metal complexes in a solvent with a reducing agent is widely used to prepare Ni NPs that exhibit high catalytic activity in various organic transformations. Intensive research has been conducted on control of the morphology and size of Ni NPs by the addition of polymers and long-chain compounds as protective agents; however, these agents typically cause a decrease in catalytic activity. Here, we report on the preparation of Ni NPs using hydrosilane (Ni-Si) as a reducing agent and a size-controlling agent.
