Palmar Plate Fixation of AO Type C2 Fracture of Distal Radius Using a Locking Compression Plate –A Biomechanical Study in a Cadaveric Model

Abstract

The stability of palmar plate fixation using a locking compression T-plate was compared with that of a conventional palmar T-plate and a dorsal T-plate in a cadaveric model of an AO type C2 fracture of distal radius. The wrist axial load transmission through the radius was tested for each fixation. The results show that, under 100N axial load, the palmar locking compression T-plate restores stability comparable to that of the intact radius, and is superior to conventional palmar or dorsal T-plates.

Volar locking plate fixation for distal radius fractures: Does age affect outcome?

“…However, the results of this study can be supported by biomechanical research, which demonstrated that the VLP device was efficient in the restoration of the normal axial force alignment without the reliance on screw engagement into the bone due to the nature of the screws, which mediate better locking mechanism into osteoporotic bone. 31 Additionally, the data proves coherent with Jupiter et al who studied ≥60 years patients and concluded that open reduction VLPs could be used to treat displaced distal radial fractures in older patients when conservative managements have failed, although our data considers the technique as primary management. 32 We cannot fully explain why older patients had better ulna deviation, but we hypothesise that it may be due to ulna shortening after fracture, which more commonly occurs in osteoporotic bone.…”

Functional and radiological outcome in distal radius fractures treated with locking compression plate

“…29 They reported that if the volarily placed titanium symmetry plate was used to fix a colles -type fracture, the distal fragment of radius to develop a dorsal angulations of about 9 degrees if early active mobilization of fingers was initiated during the postoperative period, on the other hand, Leung et al demonstrated no statistical difference between axial loading transmission though the intact radius and a distal radius fracture fix with a volar locking plate. 30 In fact, the volar locking plate showed advantages over dorsal plating in the fixation of dorsally unstable distal radius fracture. In addition, volar plate fixation is a valuable method because of decrease risk of inducing dorsal soft tissue complications.…”
