Background:
This study aimed to introduce a potential alternative percutaneous treatment for AO types C1, C2, and C3 distal radius fractures using dual-external fixator (a no-bridging cemented-pin frame and a conventional wrist-bridging external fixator).
Materials And Methods:
From January 2018 to January 2021, 52 patients (52 distal radius fractures) were treated with dual-external fixator. For comparison, 61 patients (61 distal radius fractures) were treated with a plate and screw system. Wrist function was assessed using the Mayo Wrist Score. Patient satisfaction was assessed using the Short Assessment of Patient Satisfaction. A P < 0.05 was considered statistically significant.
Results:
Fracture healing was achieved in all patients. At the final follow-up of 29 months (range, 24-34 months) vs 36 months (range, 26-39 months) (P > 0.05), the patients treated with dual-external fixator and a plate and screw system achieved mean ulnar deviations of 31° vs 29° (P < 0.05), mean Mayo Wrist Scores of 91.12 ± 5.98 vs 88.12 ± 7.54 (P < 0.05), and mean patient satisfaction scores of 23.42 ± 2.47 vs 23.04 ± 2.32 (P > 0.05).
Conclusions:
AO types C1, C2, and C3 distal radius fractures can be treated successfully using dual-external fixator. The technique is a potential alternative in addition to the conventional treatments.
Level Of Evidence:
Level IIa.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
