Fractures and diaphyseal nonunion of the femur are normally treated by intramedullary nailing. In cases in which nailing fails, nonunion is treated by reaming of the canal and substitution of the nail with one of a more adequate caliber. Rarely, however, due to unfavorable mechanical conditions or in cases of atrophic nonunion or with scarce vascularization the biological conditions for healing are absent. In cases such as these, nonunion must be treated by rigid internal fixation with a plate, aided by the use of cortical graft on the opposite side. The authors present 7 cases of diaphyseal nonunion of the femur treated between 1994 and 1996 using rigid fixation (plate and graft) as a salvage method, as a result of numerous previous failures in surgery. The results were favorable in all of the cases without complications.

Background: Clavicle fractures associated with ipsilateral coracoid process fractures are very rare, with limited literature reporting only a few cases. This study reports on 27 patients with ipsilateral concomitant fractures of the clavicle and coracoid process who were followed for more than 12 months.
Material And Methods: This retrospective study reviewed the charts of skeletally mature patients with traumatic ipsilateral clavicle and coracoid process fractures treated at the authors' institution.
Different Internal Fixation Methods for Sanders Type II and III Calcaneal Fractures: A 5-Year Retrospective Study and Finite Element Analysis.

Objective: Soft tissue defects and postoperative wound healing complications related to calcaneus fractures may result in significant morbidity. The aim of this study was to investigate whether percutaneous minimally invasive screw internal fixation (PMISIF) can change this situation in the treatment of calcaneal fractures, and aimed to explore the mechanical effects of different internal fixation methods on Sanders type III calcaneal fractures through finite element analysis.
Methods: This retrospective analysis focused on 83 patients with Sanders II and III calcaneal fractures from March 2017 to March 2022.

Background: Length unstable femoral shaft fractures in school-aged children usually demand surgical treatment, but the optimal choice remains controversial, especially in overweight adolescents. This study aimed to compare the clinical results of locking compression plates (LCP) and elastic stable intramedullary nails (ESIN) combined with temporary external fixator (TEF) in school-aged children weighing over 50 kg.
Methods: Between January 2010 and January 2018, children over 50 kg with length unstable femoral shaft fracture treated with ESIN & EF in the authors' institute were included in this study.
Biomechanical evaluation of different fixation techniques in the rotation of the maxillary occlusal plane after Le Fort I osteotomy.

Faculty of Dentistry of Pernambuco, University of Pernambuco, 50100130, Recife, Pernambuco, Brasil.
Background: To analyze the biomechanical and functional characteristics of different maxillary fixation techniques after Le Fort I osteotomy and occlusal plane rotation, using the finite element method to simulate the mechanical behavior of three different osteosynthesis approaches.
Material And Methods: This is a virtual experimental study carried out using finite element analysis to compare three different osteosynthesis techniques after Le Fort I osteotomy and rotation of the maxillary occlusal plane. Three configurations were tested: four-point fixation with "L" plates (C1), two-point fixation with "L" plates (C2), and two-point fixation with pre-modeled Lindorf plates (C3).
