Fig. 1Intrafocal pin technique of Kapandji. The two K-wires are inserted into the fracture site rather than through the distal fracture fragment both radially and dorsally. The K-wires are then levered up to reduce the fracture and advanced through the opposite proximal intact far cortex to prevent redisplacement of the distal fragments. These intrafocal pinnings of K-wires buttress the distal fragments and allow the maintenance of radial inclination and palmar tilt, respectively.

22-year-old man of extraarticular distal radius fracture without dorsal comminution was treated by Kapandji technique percutaneous pinning.
(A) Preoperative radiographs show AO classification A2 fracture.
(B) Immediate postoperative radiographs show that radial length, volar tilt and radial inclination are well restored.
(C, D, E) Radiographs at postoperative 1, 2, 4 weeks show the maintenance of reduction well.
(F) Radiographs at last follow up show excellent radiological result without significant reduction loss.
Fig. 3
55-year-old woman of intraarticular distal radius fracture with dorsal comminution was treated by Kapandji technique percutaneous pinning.
(A) Preoperative radiographs show AO classification C2 fracture.
(B) Immediate postoperative radiographs show that radial length, volar tilt and radial inclination are relatively well restored.
(C, D, E) But, radiographs at postoperative 1, 2, 4 weeks show the progressive development of reduction loss in all radiological
parameters.
(F) Radiographs at last follow up show fair radiological result with significant reduction loss.
