Abstract
Purpose
This study examined the clinical outcomes of comminuted intraarticular distal radius fractures treated by an anatomical reduction using a brick-work technique.
Materials and Methods
Seventeen patients with AO/OTA type 23-C3 distal radius fractures were enrolled in this study. An anatomical reduction of the articular surface was achieved using a brick-work technique through the dorsal approach and dorsal plates were used for fixation. The postoperative functional results were assessed with the range of motion of the wrist and the modified Mayo wrist score (MMWS). In addition, the radial length, radial inclination, volar tilt, and Lidstrom score were evaluated from the radiology results. The mean postoperative follow-up period was 13.6 months.
Results
All patients showed bony union and the mean range of motion of the injured wrists was 94% (92% to 95%) of the uninjured side. The mean MMWS was 85.3, and the functional results were excellent in 12 patients, good in 4, and fair in one at the final follow-up. Based on the final radiographic measurements, the radial length, volar tilt, and radial inclination were 11.4 mm (10.0 to 13.5 mm), 6.6° (−1.8° to 9.2°), and 21.3° (20.1° to 25.7°), respectively. The radiologic results according to the Lidstrom score were excellent in 14 patients and good in three.

(B) After elevating the dorsal comminuted fragments, the articular surface was reduced from the volar to dorsal sequence and provisional fixation with a temporary K-wire. (C) Dorsal comminuted fragments were reduced in its original position. (D) Final application of dorsal contoured plate and screws.

Posteroanterior and lateral radiographs (A), and computed tomography images (B) show central and dorsal multi-fragmentary comminution corresponding to an AO/OTA 23-C3 fracture pattern. (C) Postoperative follow-up radiographs after 6 months show complete union.

Posteroanterior and lateral radiographs (A), and three dimensional reconstructed computed tomography images (B) show dorsally displaced comminuted fragments. (C) Postoperative followup radiographs after 5 months show complete union and maintained radiographic parameters.
