Purpose
With this prospective randomized control trial (RCT), we aim to provide the outcome analyses of the three most used treatment modalities for distal end of radius (DER) fracture management in the elderly.
Methods
A prospective randomized control trial was performed. Fifty-two patients with DER fractures (AO A2, A3, C1, or C2) were randomized to the casting (n = 17), percutaneous pinning (n = 18), and the volar plating group (n = 17). Radiological measurements measured were radial inclination (RI), radial height (RH), volar tilt (VT), and ulnar variance (UV). The outcome was measured based on range-of-motion, grip strength, Patient-Related-Wrist-Evaluation (PRWE) score, and the Quick-Disabilities-of-the-Arm-Shoulder-Hand (QDASH) score.
Results
Immediate post-operative and 1-year-follow-up X-rays showed a significant difference measurement between the groups (p < 0.05). Pairwise comparisons of the casting and pinning groups (p < 0.05) and the casting and plating groups (p < 0.05) revealed significant differences at the 1-year follow-up, but not the pinning and plating groups (p > 0.05). The analysis found significant differences in clinical outcomes after 1 month of follow-up, with the plating group outperforming the other two (p > 0.05). However, after a year of follow-up, all groups had comparable outcomes; however, the plating group showed improved palmar flexion (p < 0.001), radial deviation (p < 0.001), and a lower PRWE score (p < 0.05), indicating better wrist function. Complications were more in casting group.
Conclusion
The study found a radiologically significant difference between groups throughout the follow-up, but it did not affect functional results. Clinical outcomes were similar across the groups, with plating showing better palmar flexion and radial deviation. Grip strength was also better in the plating group, but statistically insignificant. The study suggests plating should be chosen over other treatments for high-demand patients.
