“…Except this, no difference was observed in the evaluations performed in shorter and longer periods 18 . In a study, the position of the adjustable splint produced with a 3D printer in mallet finger was examined using x-ray and it was found that it was effective in terms of correction 19 . In our results, we found that the finger splint made of thermoplastic material does not allow any flexion in the PIP joint, but there is very less flexion movement in the DIP joint.…”

OBJECTIVE: Finger splints are used as a treatment option in tendon, bone, and soft tissue injuries. For immobilization, custom-made splints and prefabricated finger splints are used. In splints made for immobilization, it is aimed to limit joint movement. The aim of our study is to reveal how much custom-made splints and prefabricated finger splints limit joint motion (flexion angle in proximal interphalangeal and distal interphalangeal joints). METHODS: Custom-made splints and prefabricated finger splints were applied to the second fingers of the dominant side in a total of 40 individuals, 20 women and 20 men, not having any health problems. Individuals were asked to flex and joint motion was measured with the iPhone compass application. RESULTS: The mean distal interphalangeal joint angle values of the participants measured by prefabricated finger splints were found to be 24.27±8.29, and the mean distal interphalangeal joint angle values measured by custom-made splints was 0.52±1.50. There was a difference between the participants' distal interphalangeal joint angle values measured by prefabricated finger splints and custom-made splints (p<0.001). distal interphalangeal joint angle values measured with custom-made splints were significantly smaller than those measured with prefabricated finger splint. The mean of the participants' proximal interphalangeal joint angle values measured by prefabricated finger splints was 16.55±7.90, and the proximal interphalangeal joint angle values measured by custom-made splints was "0" for all participants. There was a difference between the participants' proximal interphalangeal joint angle values measured by prefabricated finger splints and custom-made splints (p<0.001). Distal interphalangeal joint angle values measured with custom-made splints were significantly smaller than those measured with prefabricated finger splints. CONCLUSION: According to our study, custom-made splints can significantly reduce the flexion of the finger interphalangeal joints compared to prefabricated finger splints.

“…Evidence of better performance of the customized splints, when compared with prefabricated ones, is found in the literature [11,12]. Both these types of splints can be fabricated using different types of materials available such as plaster, fiberglass, metal, foam, thermoplastics, carbon fiber, and other materials [13,14]. Also, there are different types of fabrication techniques that are used to produce these splints [14].…”

Design, Manufacturing, and Trial of a 3D Printed Customized Finger Splint for Patients with Rheumatoid Arthritis

Rheumatoid arthritis has become one of the most common inflammatory diseases and plays a major role in the disability of the population affected by it. The prevalence of finger deformities in the upper extremity caused by rheumatoid arthritis is increasing day by day, especially in low and middle-income countries such as India. For the management of these finger deformities, the splinting options are either customized or prefabricated. The performance and success of finger splinting depend on several factors, including precision, aesthetics, patient acceptance, comfort, the convenience of usage, effects, price, and side effects. However, to date, customized splints are high-cost and usually fabricated by conventional production techniques, which dominantly work on approximation. This study focused on the development of a novel finger splint through computational optimization and 3D printing for the management of boutonniere and swan neck deformity caused by rheumatoid arthritis. Twenty subjects with finger deformities were recruited, and the performance of the 3D-printed splint was characterized. The results were assessed using the nine-hole peg test and QUEST 2.0, which showed positive effects of the splint, including achievement of corrected joint positions, finger dexterity, and comfort. Such a low-cost and effective splint, with further acceptability testing, is anticipated to be a better line of conservative management for patients affected by rheumatoid arthritis.
