Optimal Duration of Longitudinal Mechanical Traction in Displaced Radius Fractures: a Prospective Non-inferiority Study (DRF-LUKS)
The goal of this clinical trial is to learn if 1 minute of mechanical traction lines up a broken wrist bone as well as 5 or 10 minutes of traction in adults (18 years and older) who come to the emergency department with a displaced distal radius fracture (a broken wrist with the bone pieces out of place) that needs to be set and put in a cast. The main questions it aims to answer are:
Is the bone position on X-ray after 1 minute of traction no worse than after 5 or 10 minutes? Bone position is measured as wrist tilt, radial inclination, radial height and ulnar variance.
At what point during traction does the bone reach its best position?
There is no separate comparison group. Each participant serves as their own comparison. Researchers will compare X-rays taken before traction and after 1, 5 and 10 minutes of traction in the same participant to see if longer traction improves bone alignment.
Participants will:
Receive standard pain relief and have their arm placed in traction with finger loops and a 5 kg weight, as in usual care Have two extra wrist X-rays (front and side view) after 1 minute and again after 5 minutes of traction, in addition to the standard X-rays before traction and after 10 minutes Have their fracture set and a cast applied as usual. Participation ends when they leave the emergency department, and there are no extra follow-up visits.

실험적: Sequential traction (1, 5 and 10 minutes)
Adults with an acute displaced distal radius fracture receive standard longitudinal mechanical traction, using finger traps on the thumb, index and middle fingers and a 5 kg counterweight. Standard wrist radiographs (PA and lateral) are taken before traction (T0) and after 10 minutes (T3). Two additional study radiographs (PA and lateral) are taken after 1 minute (T1) and 5 minutes (T2) of traction. Each participant serves as their own control. Closed reduction and casting then follow standard care. |
Continuous longitudinal traction with standardized finger traps and a 5 kg weight over a pulley on the emergency department reduction frame, lasting 10 minutes. Wrist radiographs are taken at 1, 5 and 10 minutes of traction. |
