“…Since the definition was proposed, a large number of scholars have conducted research on it from many directions and have made certain progress and have further in-depth understanding of the disease. According to the different manifestations of imaging, the disease is divided into three types: cam type (CAM-type), clamp type (PINCER-type), and mixed type (MIX type); it is believed that the disease should be diagnosed at an early stage and related treatment [10,11]. However, with a large number of clinical observations, it has been found that the x-ray signs of the so-called FAI also have a large number of manifestations in people without any hip symptoms; a study by Laborie et al found that about half of adults without hip symptoms have at least one or more FAIrelated symptoms.…”

In order to solve the problem that people often have pain in the hip joint, it is more meaningful to study femoral-acetabular impingement syndrome in the future. This article aims to study the finite element analysis of femoral-acetabular impingement based on three-dimensional reconstruction. This paper proposes a selective image matching strategy. In the feature matching stage, all images are not matched in pairs, but the corresponding camera distance between the images is calculated initially, which has little effect on the number of features and greatly reduces the time of feature matching, thereby reducing the time cost of 3D reconstruction. In this experiment, a double-blind experiment was used to check the range of motion of all hip joints. Two senior radiologists read the obtained hip joint orthographic films to screen out the hip joint orthographic films that meet the requirements. Experimental data shows that although the initial matching points of the algorithm in this paper are lower than those of the traditional algorithm, the final number of matching points is higher than that of the traditional algorithm. When the final number of patches is fixed to 10000, the initial patch required by the algorithm in this paper is more than that required by the SAD algorithm, nearly 13%, but the total storage requirement is 56.4% of the SAD algorithm, which is a big improvement.
