Abstract
Background
The usefulness of arthroscopic reduction for the intra-articular fracture of the distal radius has been reported, although it is technically difficult.
Hypothesis
Our hypothesis is that the reduction using the external fixator is useful as equivalent to the arthroscopic reduction for the intra-articular fracture of the distal radius fracture in the fixation with the volar locking plate.
Materials & Methods
The surgery was performed in both methods randomly for 40 patients; average age 64(24 to 92) years, 11 male, 29 female. Image evaluations were performed at 24 weeks after surgery. Ulnar variance, Radial inclination, Volar tilt in the X-ray image, and gap and step in the computed tomogram were evaluated. Clinical evaluation was performed at 6, 12, 24 weeks after surgery. Objective evaluations were ranges of motion and grip strength. Subjective evaluations were disabilities of the arm, shoulder, and hand (DASH).
Results
The results of image and objective evaluation had no significant difference between the two groups. DASH in arthroscopic group was significantly inferior at 24 weeks because of minor complications.
Discussion & Conclusion
The external fixator and the arthroscopy are equally valuable in reduction of articular surface.
