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

Abstract

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.

Treatment options in extra-articular distal radius fractures: a systematic review and meta-analysis

“…Among the 109 studies were 21 randomized controlled trials, 37 prospective studies, and 51 retrospective studies (Supplementary Table S1). Among the 136 cohorts, 31 reported on outcomes after plaster cast immobilization [ 18 – 48 ], 37 on K-wire fixation [ 5 , 18 , 21 , 41 , 42 , 45 , 47 , 49 – 76 ], 41 on volar plate fixation [ 4 – 6 , 54 – 56 , 60 , 61 , 72 , 74 , 77 – 107 ], 16 on external fixation [ 6 , 30 , 34 , 36 , 53 , 108 – 118 ], and 11 on intramedullary fixation [ 4 , 6 , 43 , 81 , 92 , 96 , 119 – 123 ]. Most of the included studies were of low or medium quality, 40% ( N = 44) and 50% ( N = 55), respectively.…”

Trans-styloid associated to intrafocal pinning for distal radius fracture with posterior tilt

“…Since the extrafocal pinning described by Lambotte in 1908 [1] , several techniques for pinning the distal radius have been used and have evolved over time [2,3,4,5,6,7,8,9] . The variation in methods was based on the limitations and complications of the older techniques.…”
