Objective To investigate the effect of special traction splint vs plaster immobolization in the treatment of distal radius fractures and clarify the mechanism of traction splint. Methods Total of 70 patients with displaced distal radius fractures treated conservatively were randomly divided into an experimental group ( traction splint immobolization, 35 cases) and a control group (plaster immobolization , 35 cases). There was no significant difference in age, gender, fracture type and fixation timing, and visual analog scale (VAS) for pain between the two groups (P>0.05). The fracture healing and fixation time, re-displacement, unacceptable displacement, operation rate, radius height, radial inclination angle, palmar inclination, range of motion (ROM) of radial-ulnar inclination，flection- extension and rotation, VAS for pain, hand grip strength, patient-rated wrist evaluation (PRWE) and wrist functional recovery (Gartland- Werley’s method) were compared between the two groups. Results The re-displacement, unacceptable displacement and operation rate of the experimental group were less than those of the control group, and the differences were statistically significant (P<0.05). There was no significant difference in fracture healing time and fixation time between the two groups (P>0.05). All the patients were followed-up for 10 to 18 months, with an average follow-up of 12.2 months. At the last follow-up, the radius height and radius inclination angle of the experimental group were better than those of the control group, and the differences were statistically significant (P<0.05). However, there was no significant difference in the palmar inclination, ROMs of radius-ulnar inclination, flection-extension and rotation, VAS, hand grip strength, patient-rated wrist evaluation (PRWE), and excellent to good rate of wrist function between the two groups (P>0.05). Conclusions Comparing with plaster, traction splint immobolization can better maintain the position of distal radius fracture and the height of radius, reduce the re-displacement and operation rate, and the overall effect is better.
