![]() ![]() Patients were given knee ROM rehabilitation for knee contracture. Pin site infection was common in the external fixator group. In the submuscular plating group, radiographic union was detected at an average time of 10 weeks. In the external fixator group, the fixator was removed at an average of 12.2 weeks. Results: Age of the patients ranged from 6 to 11 (average: 7.45) years in the external fixator group and from 7 to 12 (average: 9.08) years in the submuscular plating group. The average follow-up period was 2 (range: 1.5 to 4) years. The patients were evaluated for mechanism of injury, knee ROM, length of hospital stay, clinical and radiological findings and complications. Twenty patients comprised the external fixation group and 26 patients the submuscular bridge plating group. Patients and Method: Two groups of patients treated by external fixator or submuscular plating due to femoral diaphyseal spiral and comminuted fractures were included in our study. Although external fixation and submuscular plating have been extensively used in the management of pediatric femur fractures, there are few studies which have compared the results of external fixation and submuscular bridge plating in pediatric closed unstable spiral femoral diaphyseal fractures. Objective: The treatment of femoral diaphyseal fractures in children 6 to 12 years of age has changed substantially over the last two decades and continues to evolve.

In addition, La-modified structures have electronic sensor properties. ![]() Consequently, the CNT and graphene structures doped and decorated with La can be used as adsorbents for hydrogen molecules. This signifies that the La-modified CNT structures could be electronic sensors for hydrogen molecules. ![]() After the hydrogen interaction, HOMO–LUMO gap values decreased in La-modified CNT structures and increased in graphene structures. Charge transfer has occurred between the structures modified with La and the hydrogen molecule. While the adsorption energy values are better in the modification with La doping in the CNT structure, the results in the graphene structure are better in the decoration with the La atom. The fact that the adsorption enthalpy values are smaller than the liquefaction enthalpy value of hydrogen indicates that they can be used as adsorbent materials for hydrogen adsorption. It is seen that the hydrogen interaction increased significantly after the La modification on the CNT and graphene. The use of carbon nanotube (CNT) and graphene structures as doped and decorated with La atom as an adsorbent and a sensor material for hydrogen molecules was investigated by the density functional theory method. ![]()
