Treatment of the distal radius fractures with percutaneous pinning: evolution to the HK2 system

Displaced fractures of the distal radius often require reduction and fixation to improve outcome in active patients. The volar locking plate gained ground over pinning, which was the first surgical solution described. But pinning methods have since evolved with fewer complications. The authors present a clinical study of distal radius fracture fixation using the HK2 technique, where subchondral pins are connected to intra-focal pins. The results are satisfactory with a lower complication rate compared to other pinning methods. This technical improvement relaunches the pinning technique, with its two advantages, being faster and significantly cheaper than locking plates, with similar long-term functional results.
