LCP Volar Column DistalRadius Plates 2.4 mm
Description
The LCP Volar Column Plate is part of the LCP Distal Radius System 2.4 and is indicated for the fixation of intra- and extra-articular fractures and osteotomies of the distal radius. Multiple locking screw options in the head of the plate pro-vide additional options for fixation of the radial and inter-mediate columns.
Features – Anatomically contoured volar distal radius plates. – Multiple locking screw options in head of plate provide
fixation of the radial and intermediate column. – Choice of 6-, 7-, 8- or 9-hole head configurations. – Available left and right, with 3-, 4-, and 5-hole shaft
length. – Screw sizes:
– Head: locking screws B 2.4 mm – Shaft: locking B 2.4 mm, cortex B 2.4 mm,
or cortex screws B 2.7 mm – Available in stainless steel and pure titanium.
Benefits – Multiple distal locking screw options offer a fixed-angle
construct to support the articular surface, to help reduce the need for bone graft and obtain fixation in osteopo-rotic bone.
– Combi-holes in plate shaft allow locking screw fixation with angular stability in the threaded section, or compres-sion with cortex screws in the DCU section of the hole.
– Low plate and screw profile minimizes potential for tendon adhesions and soft tissue irritation.
– Polished surface and rounded edges minimize potential for tendon adhesion.

LCP Volar Column Distal Radius Plates 2.4 mm. Surgical Technique DePuy Synthes 7
Radial column
Intermediate column
Ulnar column
Three column theoryExtra-articular fractures require avoidance of malunion with angulation and shortening. Malalignment results in limita-tions of movement, changes of load distribution, mid-carpal instability and increased risk of osteoarthritis in the radiocar-pal joint.
Intra-articular fractures with articular displacement over 2 mm in the radiocarpal joint inevitably result in osteoarthri-tis and functional impairment.
The treatment of distal radius fractures should provide meticulous reconstruction of the joint surface, stable internal fixation and early functional post-operative treatment.
The distal radius and distal ulna form a three-column biomechanical construction: – The ulnar column is the distal ulna, the triangular fibrocar-
tilage and the distal radio-ulnar joint. – The intermediate column is the medial part of the distal
radius, with the lunate fossa and the sigmoid notch. – The radial column is the lateral radius with the scaphoid
fossa and the styloid process.
A dorsally displaced fracture of the distal radius shows not only dorsiflection in the sagittal plane, but also radial devia-tion in the frontal plane and supination in the transverse plane.
Stabilization after reduction requires buttressing of the intermediate column as well as the radial column.
In case of a fractured distal ulna, the ulnar column should be stabilized as well.

Screw selection
Determine what screws to use for the fixation of the plate.
Note:Plate shaft – Use locking and/or cortex screws in the shaft of the
plates. If a combination of cortex screws and locking screws is used, a cortex screw should be used first to pull the plate to the bone.
Plate head – Locking screws in the head of the plate support the
articular surface and prevent loss of reduction.
Warning: If a locking screw is used first, ensure that the plate is held securely to the bone, to avoid spinning of the plate.
Note: 2.7 mm cortex screws can only be used in the combi-nation hole of the volar plates.

Implantation
1 Implant selection
Select the plates according to the fracture pattern and anat-omy of the radius.
Note: Distinguishing left plate from right plate: Rounded side is positioned on the Radial styloid.
2Fracture reduction
Translate the shaft portion of the fracture from the ulnar to radial side at the same time to manipulate the radial column into alignment.
Once the fracture is reduced, insert K-wires or drill bits for preliminary fracture stabilization.
Perform several radiographic views of the distal radius to ensure alignment and reduction.

Implantation
Preliminary Kirschner wire fixation with short LCP drill sleeves
After fracture is reduced with Kirschner wires, apply the vo-lar column plate to fit the volar surface and insert a cortex screw B 2.4 mm into the elongated hole in the shaft. Adjust the plate position as necessary, and tighten the screw.
Note: Alternatively, a cortex screw B 2.7 mm may be inserted into the elongated hole.
Precaution: Reverse bending or use of the incorrect instru-mentation for bending may weaken the plate and lead to premature plate failure (e.g. breakage). Do not bend the plate beyond what is required to match the anatomy.
The plate can be fixed distally with Kirschner wires or drill bits inserted through the short LCP drill sleeves, if desired.
The order of screw insertion and the use of Kirschner wires may vary depending on the fracture pattern and reduction technique.
Perform several radiographic views of the distal radius to ensure alignment and reduction.

Note:The short LCP drill sleeves mounted to the plate before surgery will help reduce surgery time, and they will double as K-wire holes for preliminary plate fixation.

22 DePuy Synthes LCP Volar Column Distal Radius Plates 2.4 mm. Surgical Technique
Implantation
Insert locking screws B 2.4 mm into the distal part of the plate, selecting hole locations appropriate to the particular fracture pattern. For screw insertion, remove K-wires and LCP drill sleeves as needed (see illustration). It is important to ensure the screws do not penetrate the far cortex.
The order of screw insertion and the number of screws used will depend on the fracture pattern.
Precaution: When finished with the fixation, promptly remove all unused short LCP drill sleeves from the plate to ensure that they are not implanted in the patient. The hold-ing sleeve for T8 Stardrive screwdriver shaft can be used for short LCP drill sleeve removal.
RecommendationInsert the locking screws with the torque limiter.

Final fixation
Insert additional proximal screws. Determine whether 2.4 mm locking or cortex screws will be used in the shaft of the plate.
For locking screws, carefully insert the LCP drill sleeve 2.4 with scale in line with the hole’s axis until it is seated in the desired locking hole. Drill with the drill bit B 1.8 mm.
Read the screw length directly from the laser mark on the drill bit, or use the corresponding Depth Gauge to determine the screw length.
RecommendationInsert the self-tapping locking screws with the torque limiter.
For cortex screws, use the universal drill guide 2.4. Drill threaded holes with the drill bit B 1.8 mm and gliding holes for compression with the drill bit B 2.4 mm. Then, measure the screw length using the corresponding Depth Gauge.
Note: When cortex screws B 2.7 mm are inserted, use the universal drill guide 2.7. Drill threaded holes with the drill bit B 2.0 mm and gliding holes for compression with the drill bit B 2.7 mm.

To remove locking screws, first unlock all screws from the plate; then remove the screws completely from the bone. The last screw removed should be a non-locking screw of the shaft. This guarantees the plate not to spin when locking screws are removed.

MRI Information
Torque, Displacement and Image Artifacts according to ASTM F 2213-06, ASTM F 2052-06e1 and ASTM F 2119-07Non-clinical testing of worst case scenario in a 3 T MRI system did not reveal any relevant torque or displacement of the construct for an experimentally measured local spatial gradient of the magnetic field of 3.69 T/m. The largest image artifact extended approximately 169 mm from the construct when scanned using the Gradient Echo (GE). Testing was conducted on a 3 T MRI system.
Radio-Frequency-(RF-)induced heating according to ASTM F 2182-11aNon-clinical electromagnetic and thermal testing of worst case scenario lead to peak temperature rise of 9.5 °C with an average temperature rise of 6.6 °C (1.5 T) and a peak temperature rise of 5.9 °C (3 T) under MRI Conditions using RF Coils (whole body averaged specific absorption rate [SAR] of 2 W/kg for 6 minutes [1.5 T] and for 15 minutes [3 T]).
Precautions: The above mentioned test relies on non-clini - cal testing. The actual temperature rise in the patient will depend on a variety of factors beyond the SAR and time of RF application. Thus, it is recommended to pay particular attention to the following points: – It is recommended to thoroughly monitor patients under-
going MR scanning for perceived temperature and/or pain sensations.
– Patients with impaired thermoregulation or temperature sensation should be excluded from MR scanning proce - dures.
– Generally, it is recommended to use a MR system with low field strength in the presence of conductive implants. The employed specific absorption rate (SAR) should be reduced as far as possible.
– Using the ventilation system may further contribute to reduce temperature increase in the body.
