It has not been tested for heating, migration or image artifact in the MR environment. The safety of the Distal Radius Sterile Kit in the MR environment is unknown. Scanning a patient who has this device may result in patient injury.

The use of the 2.4/2.7 mm VA LCP Two-Column Volar Distal Radius Plate, Extra-Long in patients where the growth plates have not fused or will be crossed may result in premature closure of the physis and bone growth inhibition.

They contain only the instruments needed to perform one distal radius surgery with the following DePuy Synthes Variable Angle radius plates: 2.4 mm VA LCP Two-Column Distal Radius Plates 2.4/2.7 mm VA LCP Two-Column Distal Radius Plates, Extra-Long 2.4 mm VA LCP Extra-articular Distal Radius Plate 2.4 mm VA LCP Dorsal Distal Radius Plates Plates and screws are available single-packed in sterile packaging. Sizing templates In addition, sterile sizing templates are available separately to determine the correct plate head width of VA LCP Two-Column Distal Radius Plates. Implant removal screwdriver The single-use T8 screwdriver is designed to facilitate implant removal without the need for a sterile instrument kit. Note that the screwdriver tip is Note: All implants and instruments of the Distal non-retaining to facilitate maximum torque transmission. Radius Sterile Kit are single use. Do not resterilize. Dispose of all unused items after surgery.

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 Distal Radius Sterile Kit Surgical Technique Implantation Steps 1. Select implant Instrument 03.111.120S 2.4 mm VA LCP 2-Column Volar Distal Radius Plate Templates, sterile Sizing templates Double-sided sterile sizing templates may be used to identify the desired plate size prior to opening a distal radius sterile kit. Templates are available for 2.4 mm VA LCP Two-Column Volar Distal Radius Plates. Sizing template choices, for 2.4 mm VA LCP Two-Column Volar Distal Radius Plates (narrow, standard, wide head sizes). Sizing templates 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 template 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 sizing template. The template’s distal lip is slightly lower on the radial side. Note: Excessive and repetitive bending of the templates should be avoided. Sizing templates are double-sided (L and R version) Distal Radius Sterile Kit Surgical Technique DePuy Synthes 11 Implantation Steps 2.
