4.5 mm LCP® Medial Proximal Tibia Plates

The DePuy Synthes 4.5 mm LCP® Medial Proximal Tibia Plate is part of the LCP Periarticular Plating System, which merges locking screw technology with conventional plating techniques.

The 4.5 mm LCP Medial Proximal Tibia Plate is available in stainless steel and has a limited-contact shaft profile. The head and neck portions of the plate accept 5.0 mm cannulated locking and 5.0 mm cannulated conical screws. The screw hole pattern allows a raft of subchondral locking screws to buttress and maintain reduction of the articular surface. This provides fixed-angle support to the tibial plateau.

The Locking Compression Plate (LCP) System has Combi holes in the plate shaft that combine a dynamic compression unit (DCU) hole with a locking screw hole. The Combi hole provides the flexibility of axial compression and locking capability throughout the length of the plate shaft.

Note: For information on fixation principles using conventional and locked plating techniques, please refer to the DePuy Synthes Large Fragment Locking Compression Plate (LCP) Surgical Technique.

Indications

The 4.5 mm LCP® medial proximal tibia plates are intended to buttress metaphyseal fractures of the medial tibia plateau, split-type fractures of the medial tibia plateau, medial split fractures with associated depressions and split or depression fractures of the medial tibia plateau. The plates may also be used for fixation of the proximal quarter (lateral and medial) of the tibia, as well as segmental fractures of the proximal tibia.

The 4.5 mm version may also be used for fixation of nonunions and malunions of the medial proximal tibia and tibia shaft, as well as opening and closing wedge tibial osteotomies.

Page 7: Part of the DePuy Synthes LCP Periarticular Plating System ...synthes.vo.llnwd.net/o16/LLNWMB8/US Mobile/Synthes... · Fixation. 3rd ed. Berlin Heidelberg New York: Springer. 1991

Complete the preoperative radiographic assessment and prepare the preoperative plan. Determine plate length and instruments to be used.

Note: Determine proximal screw placement and screw lengths to ensure proper screw placement in the metaphysis.

Position the patient supine on a radiolucent operating table. Visualization of the proximal tibia under fluoroscopy in both the lateral and AP views is necessary.

Precautions: – Instruments and screws may have sharp edges or moving

joints that may pinch or tear user’s glove or skin .– Handle devices with care and dispose worn bone cutting

instruments in an approved sharps container.

Note: Prior to reduction, application of an external fixator or large distractor may facilitate visualization and reduction of the joint.

Reduce the fracture fragments and confirm reduction using image intensification. Fragments may be reduced using independent Kirschner wires; however, K-wire holes are also provided on the plate to help achieve provisional reduction, plate position, or fixation.

The locking screws do not provide interfragment or plate-to-bone compression; therefore, any desired compression must be achieved with traditional lag screws or 5.0 mm cannulated conical screws. The articular fragments must be reduced and compression must be obtained prior to applying the 4.5 mm LCP Medial Proximal Tibia Plate with locking screws.

Note: To verify that independent lag screws will not interfere with plate placement, hold the plate to the bone.

Apply the distractor to assist in the visualization and reduction of the joint.

Insert guide wireWhile the plate is placed against the bone, insert the 2.5 mm drill tip guide wire through the 2.5 mm wire guide in the central screw hole in the plate head. It is imperative to drill using fluoroscopy to ensure proper screw trajectory and screw placement. Advance the guide wire through to the lateral cortex or to the desired screw tip location.

Determine proper screw trajectory by using clinical examination and fluoroscopy to confirm:– Guide wire trajectory in the proximal locking hole is

parallel to the joint and the reduction is maintained;

– That the screw and plate placement will be consistent with the preoperative plan; and

– Alignment of the plate to the shaft of the tibia is correct in both the AP and lateral views. Placement of the plate at this point will determine final flexion/extension.

Measure for screw lengthMeasure for screw length using the cannulated screw measuring device.

Notes: – The measuring device must contact the end of the wire

guide for an accurate measurement. – The self-drilling, self-tapping flutes of the 5.0 mm

cannulated conical screws make predrilling and pretapping unnecessary in most cases. If necessary, in dense bone, the lateral cortex can be predrilled with the 4.3 mm cannulated drill bit.

Instruments

321.12 Articulated Tension Device

398.81 Bone Forceps or 398.813 Plate Holding Forceps

Reduce the tibial plateau to the shaft of the tibia, using indirect reduction techniques whenever possible. Using atraumatic technique, secure the plate to the tibial shaft with bone forceps.

Confirm rotational alignment of the extremity by clinical examination.

Once reduction is satisfactory, and if it is appropriate based on the fracture morphology, the plate should be loaded in tension using the articulated tension device.

Note: With multifragment fractures, it may not always be possible or desirable to achieve anatomic reduction of the fracture. However, in simple fracture patterns, the articulated tension device may facilitate anatomic reduction. This device may be used to generate either compression or distraction.

7Insert screws in plate shaft

In addition to having threaded locking holes, the plate functions similarly to DCP plates which offer the ability to axially compress fracture fragments. Therefore, a combination of cortex screws and locking screws may be used.

Notes: – If a combination of cortex (1) and locking screws (2) is

used, a cortex screw should be inserted first to pull the plate to the bone.

– If locking screws (1) have been used to fix the plate to a fragment, subsequent insertion of a cortex screw (2) in the same fragment without loosening and retightening the locking screw is not recommended.

5.0 mm Cannulated Locking and Cannulated Conical ScrewsThe screw design enhances fixation and facilitates the surgical procedure.

Screw headThe conical head simplifies alignment in the plate hole. This is of particular importance when using locking screws. The threaded screw head must align with the plate hole threads to provide a secure screw/plate construct. To ensure proper alignment and prevent cross-threading, the appropriate threaded wire guide or drill guide must always be used.

Large diameter screw coreThe large diameter screw core improves bending and shear strength, and distributes the load over a larger area in the bone.

Thread profileThe shallow thread profile of the locking screws is necessary to provide a larger core. This is appropriate since locking screws do not rely on compression between the plate and the bone to maintain stability. When required, interfragmentary compression can be achieved with the partially threaded cannulated conical screws, especially when near the articular surface.
