Objective To summarize the general concept of lateral wall, the causes of lateral wall injury, and surgical strategies in order to improve the understanding of lateral wall and reduce the complications of operation. Methods The related literature on lateral wall was extensively reviewed, summarized, and analyzed. Results The superior extent of the lateral wall is vastus lateralis ridge and the inferior extent is the intersection between the lateral femoral cortex and a line drawn at a tangent to the inferior femoral neck. The integrity of the lateral wall is important to prevent the failure of fixation and reoperation of intertrochanteric fractures. The main causes of injury are that there is no suitable typing criteria as a guide, the fracture pattern shown by X-ray does not match with the actual situation of the fracture, the type of fracture is special, and the operation is improper. The main treatment is to reconstruct the lateral wall and choose different reconstruction methods according to different fracture patterns. Conclusion The lateral wall is very important for the treatment of intertrochanteric fracture. Lateral wall fracture should be internal fixation in order to minimize the risk of reoperation.
ObjectiveTo summarize the research progress on the calcitonin gene-related peptide (CGRP) and receptor activator of nuclear factor κB (RANK)/receptor activator of nuclear factor κB ligand (RANKL)/osteoprotegerin (OPG) system during bone reconstruction to provide theoretical basis for further research on the prevention and treatment of bone-related diseases.MethodsThe relevant research results at home and abroad in recent years were analyzed and summarized.ResultsCGRP and RANK/RANKL/OPG system play important regulatory roles in the bone reconstruction.ConclusionAt present, the research on the mechanism of CGRP and RANK/RANKL/OPG system in bone reconstruction is insufficient. Therefore, it is necessary to study further on the process and interrelation of CGRP and RANK/RANKL/OPG system in bone reconstruction to confirm their mechanism, which will bring new ideas and methods for the treatment of bone related diseases in clinic.
ObjectiveTo summarize the related research results of minimally invasive treatment of anterior pelvic ring fracture, and to improve the understanding of minimally invasive treatment of anterior pelvic ring fracture.MethodsThe literature of minimally invasive treatment of anterior pelvic ring fracture at domestic and overseas in recent years was reviewed, and the reduction and fixation methods of minimally invasive treatment were summarized and analyzed.ResultsThe pelvic reduction frame may be an effective auxiliary method for minimally invasive reduction of pelvis. The fixation methods of anterior pelvic ring include percutaneous screw fixation, stent fixation, and percutaneous plate fixation.ConclusionOne kind of fixation is not applicable to all types of anterior pelvic ring fracture, and the fixation method should be selected according to the type of fracture and the patient’s condition to minimize the complications.
