Fig. 1The prebent wire is firmly fixed to the drill chuck.
Fig. 2The wire is inserted through the ulnar cortex of the little finger metacarpal base, after 5 mm incision.
Fig. 3Drive the wire into the fracture site like a guide pin of the interlocking nail system.
Fig. 4Prebent tip of the wire is secured at the subchondral bone of the metacarpal head after closed reduction under the C-arm.
Fig. 5A 46-year old man sustains a 5th metacarpal neck fracture with 35° angulation deformity in oblique radiograph.
Fig. 6Postoperative radiographs show 0° residual angulation after pin fixation.
Fig. 7Four-month postoperative radiographs show good union without any reduction loss.
Fig. 8Phoptograhs show full range of motion.
Fig. 9The height of the K-wire is proportionate to the bending angle. H: Thickness of K-wire+h, b: Length of prebent wire, a: Angle, h: b sin a.
