Purpose:
3D-printed models rapidly evolving in orthopaedic. Studies show that 3D-printed models used for preoperative planning improve a better understanding of fracture morphology and reduce operative time, blood loss and frequency of fluoroscopy, but there are no studies that investigated possible advantages in the outcomes and complications for the treatment of distal radius fracture (DRF). Our study aims to evaluate short-term functional results and complications between two groups treated DRF using 3D-printed models for preoperative planning and without. We hypothesize that the addition of 3D-printed models would improve functional outcomes and reduce complication rates.
Methods:
66 randomized cases of DRF AO/OTA C type were enrolled and divided into "Control group" (n = 33) and "3D-printed model group" (n = 33). Personalized 3D-printed models were created. The primary outcomes were: Patient-Rated Wrist Evaluation questionnaire, Quick Disabilities of the Arm, Shoulder and Hand Score questionnaire, and complications. The secondary outcomes were: measurement of the range of motions, grip strength, radiological evaluation, and the visual analogue scale. Assessments were measured at 6 weeks, 3 months, and 6 months intervals.
Results:
We found that the integration of the 3D-printed model in preoperative planning decreased complication incidence significantly - from 30.3% in the "Control group" to 6.1% in the "3D-printed model group", p = .022. But we did not find a difference in functional and radiological outcomes.
Conclusion:
The 3D-printed models for preoperative planning surgically treating DRF AO/OTA C type can help minimize the complication rate, however, they can't improve functional outcomes in the short-term results.
Level Of Evidence:
Level I randomized controlled study.
