Clinical Trial Summary

The aim of this prospective randomized trial is the acquisition and evaluation of data to assess the relevance, feasibility and safety of forearm casts based on 3D-printing technology in the nonoperative treatment of distal radius fractures.


Description:

The study design is planned according to similar studies investigating the treatment of distal radius fractures. Upon the patient's arrival at the emergency unit, the distal radius fracture is examined following the same scheme as before. The wrist is x-rayed in two planes. If there is a distal radius fracture and none of the exclusion criteria apply, the patient is included in the study after giving their consent in writing. The patients are then assigned to the "conventional cast" group (Group A) or the "3D print cast" group (Group B) in randomized trial, either immediately during the emergency consultation or within a week during hand surgery consultation hours. For initial immobilization, a thermoplastic cast splint is used as before. Depending on the randomization, the cast is changed to a Scotchcast cast (Group A) or a 3D printed cast (Group B). Further treatment of both groups occurs based on the same algorithm as before (see below). The cast for Group B are produced using 3D print technology based on software by a Belgian company, our collaborators: The patient's forearm is scanned with a tablet (duration: approx. 5 min), whereupon the cast is printed overnight according to the scan (duration: approx. 4h) and adjusted to the patient during the next appointment. The patients are examined after 1, 6, 12, 26 and 52 weeks in the outpatient clinic. Follow up x rays, patient satisfaction and clinical efficacy questionnaires and clinical examinations are conducted.

Intervention

Device:
3D-printed cast
The 3D-printed casts are produced using 3D print technology based on software by Belgian software company: The patient's forearm is scanned with a tablet (duration: approx. 5 min), whereupon the cast is printed overnight according to the scan (duration: approx. 4h) and adjusted to the patient during the next appointment.
Conventional cast
A conventional plaster cast is applied for treatment of the distal radius fracture.
