Intramedullary repair device against volar plating in the reconstruction of extra-articular and simple articular distal radius fractures ; a randomized pilot study . PURPOSE This prospective randomized pilot study reports our institutional experience and early results using Sonoma Wrx ( Sonoma Orthopedic Products , Santa Rosa , CA ) in the treatment of extra-articular and simple intra-articular distal radius fractures . MATERIAL AND METHODS A total of 64 patients , were enrolled in the study . They were considered eligible if they had ; unstable extra-articular distal radius fractures and simple intra-articular distal radius fractures suitable for closed reduction ( AO types ; A2.2 , A2.3 , A3.1 C2.1 , C2.2 ) . Patients in group I received intramedullary fixation using the Sonoma Wrx device and patients in group II received standard volar locking plate fixation . Radiographic criteria of acceptable healing were used for evaluation . RESULTS Two groups were similar in terms of baseline characteristics . Mean time of operation was significantly shorter in Group 1 vs. in group 2 ( 36.81 ± 7.11 vs. 48.97 ± 5.9 minutes , p = 0.001 ) . Time to healing of the fracture was not different between two groups ( 5.45 ± 1.09 vs. 5.70 ± 1.04 weeks for Group 1 vs. 2 , respectively p = 0.36 ) . Overall complications occurred in 9 patients in group 1 and in 15 patients in group 2 ( p = 0.17 ) . Follow-up was completed in all patients with a median time of 12 months and 13 months in group 1 and 2 , respectively . On radiographic evaluation radial inclination , radial height and volar tilt were not significantly different between group 1 and 2 , respectively . There were no significant differences between two groups in regard to wrist rotational degrees measured in last follow-up visit . CONCLUSION Sonoma Wrx Device is reliable and effective in terms of achieving satisfactory outcomes in treatment of distal radius fractures . It may be reasonable to use this device to prevent complications that are related to extensive soft tissue dissection .
