Volar locked plating of dorsally displaced fractures of the distal radius .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(2):97 Acta Orthop. 2011 Feb;82(1):76-81.63 patients with distal radius fractures were randomized to treatment with either volar locked plating or bridging external fixation, to compare functional and radiographic outcomes. Short-term outcomes at 3 and 6 months favored the volar locked plating group in terms of Disabilities of the Arm, Shoulder, and Hand (DASH) scores,Patient related wrist evaluation (PRWE) scores, grip strength and range of motion. However, by 12 months, many of the outcomes between the two groups had become similar.

Der Fragilitätsindex ist ein Instrument, das bei der Interpretation signifikanter Ergebnisse hilft und ein Maß für die Stärke eines Ergebnisses liefert. Der Fragilitätsindex gibt die Anzahl der aufeinanderfolgenden Ereignisse an, die zu einem dichotomen Ergebnis hinzugefügt werden müssen, damit das Ergebnis nicht mehr signifikant ist. Eine kleine Zahl steht für ein schwächeres Ergebnis und eine große Zahl für ein stärkeres Ergebnis.
Warum wurde diese Studie jetzt benötigt?
Recent studies have indicated promising patient outcomes for open reduction and internal fixation with volar locked plating of unstable distal radius fractures with dorsal displacement. Proposed benefits include adequate fracture stabilization and anatomic reduction, expediting early range of motion. However, the choice of internal fixation over external fixation remains unsupported in the literature. Thus, this study was required to investigate the functional and radiographic outcomes of volar locked plating.
Was war die wichtigste Forschungsfrage?
Does internal fixation with volar locked plating provide superior outcomes in terms of function and radiographic measures compared to external fixation, in patients with dorsally displaced fracture of the distal radius?
- Statistically significant improvements in DASH scores were observed in the volar-plated group versus the external fixation group at the 3 month (9 vs. 27; p<0.001) and 6 month follow-ups (6 vs. 14; p=0.008). This result failed to achieve significance at the 12 month follow-up (7 vs. 11; p=0.1).
- Statistically significant improvements in PRWE were similarly observed in the volar-plated group over the external fixation group at the 3 (12 vs. 31; p<0.001) and 6 month follow-ups (9 vs. 17; p=0.02). This result failed to achieve significance at the 12 month follow-up (11 vs. 15; p=0.3).
- Grip strength and range of motion (extension, supination, and pronation) were statistically superior in the volar plated group versus the external fixation group at the 3 month and 6 month follow-up points (p<0.05)
- The volar group demonstrated significantly reduced axial shortening (at all time points; p<0.001) and dorsal angulation (at 12 months; p=0.05) of the radius following radiographic analysis.
- 12 patients in the external fixation group and 7 patients in the volar locked plate group experienced complications over 1 year.
Was sollte ich mir besonders merken?
The volar plated group demonstrated superior patient perceived functional outcomes (DASH) and patient related wrist evaluation (PRWE) scores during early follow-up (up to 6 months); however, these benefits diminished in comparison to external fixation over time (12 months). Similar trends were observed for grip strength, whereas extension, supination, and pronation, and reduction in axial shortening remained significantly better at all follow-up periods.
Wie wird sich dies auf die Behandlung meiner Patienten auswirken?
The authors conclude that volar plating should be preferentially implemented for patients seeking rapid recovery of wrist function. The use of an external method is still applicable and offers advantages, such as cost and invasiveness. However, the possibility of late future complications with plating needs to be investigated, and the small sample size of the study should be taken into consideration.
