Abstract:Objective To analyze the correlation between musculoskeletal ultrasound findings and Oswestry Disability Index (ODI) in the third lumbar transverse process syndrome.Methods The clinical data of 121 patients with the third lumbar transverse process syndrome admitted to Hebei Hospital of Traditional Chinese Medicine from January 2019 to February 2021 were analyzed as the observation group, and 50 healthy people who underwent physical examination in the hospital during the same period were set as the control group. The musculoskeletal ultrasound was performed before and after the treatment, and ODI was used to assess the lumbar function of patients before and after the treatment. The correlation between ultrasound findings and ODI was analyzed.Results The musculoskeletal ultrasound and ODI scores were higher in the observation group than those in the control group before the treatment (P < 0.05). After the treatment, the musculoskeletal ultrasound and ODI scores were lowered in the observation group (P < 0.05). The musculoskeletal ultrasound score was positively correlated with the ODI score both before and after the treatment (r = 0.735 and 0.681, P = 0.009 and 0.018, respectively). The serum levels of interleukin (IL)-6, IL-10 and tumor necrosis factor-α (TNF-α) in the observation group were higher than those in the control group both before and after the treatment, while they were lower after the treatment relative to those before the treatment in the observation group (P < 0.05). The multivariable Logistic regression analysis revealed that the musculoskeletal ultrasound score [O^R = 1.881 (95% CI: 1.239, 2.856) ], ODI score [O^R = 1.848 (95% CI: 1.246, 2.740) ], IL-6 [O^R = 1.818 (95% CI: 1.234, 2.681) ], IL-10 [O^R = 1.868 (95% CI: 1.226, 2.847)], and TNF- α [O^R = 1.837, (95% CI: 1.224, 2.756) ] were factors affecting the development of the third lumbar transverse process syndrome (P < 0.05).Conclusions There is a positive correlation between the musculoskeletal ultrasound findings and the ODI score in patients with the third lumbar transverse process syndrome. The musculoskeletal ultrasound score, ODI score, and the levels of IL-6, IL-10 and TNF-α are independent factors influencing the development of the third lumbar transverse process syndrome.
