Summary
Pooled estimates of risk from four randomized controlled trials (RCT) or quasi-RCTs
that compared percutaneous pinning to external fixation for the treatment of distal
radial fractures indicate that there are no differences between these two treatments
with respect to clinician reported outcomes, x-ray outcomes, and most complications.
For reflex sympathetic dystrophy (RSD), however, a 70% relative risk reduction was
seen for patients treated with percutaneous pinning compared with those treated with
external fixation. Results regarding treatment effect on range of motion are inconclusive.
Only four modest-sized trials, each involving different fracture types, pinning techniques
and fixation methods were available. Additional methodologically rigorous comparative
studies are needed to clarify if percutaneous pinning or external fixation is preferred
for the treatment of distal radial fractures.
