Abstract:
Objective:To evaluate the elbow joint function of patients with endemic skeletal fluorosis based on Mayo elbow joint function score and to study its application value.Methods:Based on the monitoring results of drinking water-borne endemic fluorosis in Gansu Province from 2018 to 2023, and the results of the 2019 survey on the current cases of endemic diseases, 8 typical endemic counties were selected from 48 counties with drinking water-borne endemic fluorosis. A cluster sampling method was used to investigate all adult skeletal fluorosis patients over 25 years old in the endemic fluorosis villages under the jurisdiction of the 8 counties. A total of 1 096 skeletal fluorosis patients were included as study subjects. By extracting demographic basic information, follow-up records, elbow joint X-ray films, diagnostic information, and the Mayo elbow joint function score scale of patients, a retrospective analysis was conducted on the distribution characteristics of the Mayo elbow joint function score in different genders, ages, clinical grades, disease duration, and Kellgren-Lawrence (K-L) grading of osteoarthritis.Results:(1) The distribution of total scores on the scale: 638 cases (58.21%) were rated as "poor" (< 60 points), 345 cases (31.48%) were rated as "fair" (60 - 74 points), 96 cases (8.76%) were rated as "good" (75 - 89 points), and 17 cases (1.55%) were rated as "excellent" (≥90 points). There were statistically significant differences in the total score grading of the scale among patients with different genders, ages, clinical grades, disease duration, and K-L grading of osteoarthritis (χ 2 = 44.90, 147.20, 264.41, 211.96, 262.85, P < 0.001). (2) The scores of each dimension of the scale: the joint stability dimension scores were compared among different ages, clinical grades, disease duration, and K-L grading of osteoarthritis, and the differences were statistically significant ( P < 0.05). The scores of joint pain, range of motion, and daily living ability dimensions were compared among different genders, ages, clinical grades, disease duration, and K-L grading of osteoarthritis, and the differences were statistically significant ( P < 0.05). Conclusions:Based on the Mayo elbow joint function score scale, patients with endemic skeletal fluorosis have relatively poor elbow joint function. The scores of each dimension of the scale are influenced by factors such as genders, ages, clinical grades, disease duration, and joint degeneration. The distribution of scale scores is consistent with the clinical reality of endemic skeletal fluorosis and has certain application value in assessing disease condition.
