The Role of Personalized Stenosing Tenosynovitis Brace Therapy Based on 3D Printing Technology: A Prospective Cohort Study.

Objective: To explore the clinical effect of personalized brace based on 3D printing technology in the treatment of stenosing tenosynovitis.

Methods: From September 2021 to June 2023, 20 patients with stenosing tenosynovitis were collected and randomly divided into the experimental group and the control group, with 10 cases in each group, and each patient signed an informed consent. The experimental group was treated with personalized brace combined with External Diclofenac Diethalamine Emulgel, and the control group was treated with External Diclofenac Diethalamine Emulgel, and the clinical efficacy and pain scores of the two groups were compared.

Results: After 8 weeks of treatment, the degree of pain relief, metacarpophalangeal joint mobility and proximal interphalangeal joint mobility of the experimental group were significantly higher than those of the control group. The activity pain scores of both groups were reduced, but the experimental group was significantly lower than the control group (p < 0.05).

Conclusion: For the treatment of patients with stenosing tenosynovitis, it is recommended to use personalized stenosing tenosynovitis brace therapy based on 3D printing technology combined with External Diclofenac Diethalamine Emulgel at the first visit, which can significantly reduce finger pain and improve hand function.
