Abstract

Developmental hip dysplasia is a clinically common congenital hip disease and a common cause of long-term
hip pain. Therefore, the study of hip joint development and pathology of dislocation of round ligament tissue is
of great significance for the patients to cure. This paper mainly studies the pathological changes of hip joint
development and dislocation of round ligament tissue observed by exercise with polarized light microscope. In
this paper, 56 patients were selected for pathological verification of hip joint by polarized light microscope, and
hip muscle muscle verification test by surface electromyography (sEMG) method. The data is processed and
analyzed offline by Matlab software on the collected EMG signals. The EMG signals from the beginning to the
end of a single grasping process are intercepted in turn as a section of EMG signals. EMG data were collected at
the experimental time of 30s. Experimental data show that the round ligament of femoral head is obviously
hyperplastic and hypertrophic in developmental dislocation of hip joint. Although the morphology increases
with age and the dislocation increases the hyperplasia and hypertrophy of the round ligament is not statistically
significant (P>0.05), but Histologically, I collagen increased star, and type I collagen content decreased, the
difference was statistically significant (P<0.01). The experimental results show that due to sustained stress
greater than the physiological range, decompensated changes in tissues and organs, decompensated hyperplasia
of the round ligament (partial fracture and contraction), which in turn hinders the reduction of the femoral head
and aggravates the dislocation of the hip joint Degree, histology manifests as disordered collagen synthesis and
degradation, changes the number and diameter of collagen fibers, which affects the structure and mechanical
properties of collagen fibers, and further causes corresponding changes in tissues and organs.
