Dissect between the FCR and the radial artery, exposing the pronator quadratus. Detach the pronator quadratus from the lateral border of the radius and elevate it toward the ulna. Note: Leave the volar wrist capsule intact to avoid devascularization of the fracture fragments and destabilization of the volar wrist ligaments. 10 DePuy Synthes Sterile Distal Radius Kit Surgical Technique Implantation Steps 1. Select implant Instrument 03.111.120S Trial Implants for VA-LCP Two-Column Distal Radius Plate 2.4, sterile Trial implants Double-sided sterile trial implants may be used to identify the desired plate size prior to opening a distal radius sterile kit. Trial implants with 3 shaft holes are available for VA-LCP Two-Column Volar Distal Radius Plates 2.4. Trial implant choices, for VA-LCP Two-Column Volar Distal Radius Plates 2.4 (narrow, standard, wide head sizes). Trial implants are marked with Left (L) and Right (R) as well as the corresponding plate type (narrow, standard, wide). Select the correct distal radius sterile kit according to the trial implant matching the bone and fracture pattern with respect to side (left and right, facing up) and size (narrow, standard, wide). Precaution: Ensure proper plate selection by verifying the L (left) and R (right) etching on the trial implant. The trial implant’s distal lip is slightly lower on the radial side. Note: Excessive and repetitive bending of the trial implants should be avoided. Trial implants are double-sided (L and R version).

Reduce fracture and position plate Instrument 292.120 Kirschner Wires Ø 1.25 mm, with trocar tip Reduce the fracture The reduction method will be fracture-specific. Position plate Apply the plate to fit the volar surface. The order of screw insertion and the use of K-wires may vary depending on the fracture pattern and reduction technique. If necessary, use 1.25 mm K-wires inserted through the desired Kirschner-wire hole to temporarily fix the plate distally. The distal K-wire holes of the plate are designed to indicate the nominal screw trajectory angle of the screw hole medial to the respective K-wire hole.
