Summary
Customized 3D-printed wrist-thumb orthoses offer a feasible and effective treatment for De Quervain
Area of Science:
- Orthotics and Prosthetics
- Rehabilitation Engineering
- Musculoskeletal Disorders
Background:
- Conventional wrist-thumb orthoses present challenges in anatomical fit and patient comfort.
- Three-dimensional (3D) printing offers potential for patient-specific orthosis design, enhancing usability in rehabilitation.
Purpose of the Study:
- To assess the feasibility, clinical outcomes, and patient satisfaction of customized 3D-printed wrist-thumb orthoses for De Quervain's tenosynovitis.
Main Methods:
- A prospective observational study involving 40 patients with De Quervain's tenosynovitis.
- Comparison between conventional thumb spica splints and customized 3D-printed orthoses.
- Evaluation of pain (VAS) and function (QuickDASH) at multiple time points; satisfaction assessed via QUEST 2.0.
Main Results:
- Both orthosis types showed significant reductions in pain and functional disability.
- The 3D-printed group demonstrated numerically greater improvements in VAS and QuickDASH scores.
- High patient satisfaction (QUEST scores 3.0-4.5) and no reported adverse events with 3D-printed orthoses.
Conclusions:
- Customized 3D-printed wrist-thumb orthoses are feasible and improve pain, function, and satisfaction in De Quervain's tenosynovitis.
- Descriptive trends suggest advantages for 3D-printed designs.
- Further research with larger samples and inferential statistics is recommended.
