[Metaphysis fracture of the distal radius: Kapandji's or Py's pinning?].
The authors report a prospective and randomized study comparing two pinning techniques for fractures of the distal radius. The series compared 42 patients treated by Kapandji's intrafocal pinning (Group I) and 46 patients treated by Py's isoelastic pinning (Group II). Secondary displacement was observed in 7 patients in group I and in 2 patients in Group II. Secondary displacement of K-wire was observed in 6 patients in group I and in no patient in group II. Functional results were analysed according to jakim's criteria. A significant difference was observed between the two groups, for global scores, objectives scores and radiological scores, with better results for Py's pinning. No significant difference was observed for subjective scores advantages of Py's pinning were: stability of isoelastic wires preventing posterior comminution and no need for radioscopic control. Kapandji's pinning is proposed in cases of lower and unstable fractures in teenagers without focal comminution and in T fractures. In the other cases of metaphyseal fractures with posterior displacement, Py's pinning could be proposed.
