2 DePuy Synthes LCP Locking Compression Plate Surgical Technique
System overview
LCP Locking Compression Plate Angular stable implant
Angular stable support of fragments regardless of bone quality
May reduce the risk of primary and secondary loss of reduction even under high dynamic loading
Limited plate-periosteum contact
Locking screws provide hold also in osteoporotic bone and in multiple fragment fractures
Stability of the implant and the con-struct: Locking screws can be placed in each locking hole of the plate
Because the screws are tightly locked in the plate: – There is no tension on the bone – Compression is reduced between
the plate and bone – The periosteum is undamaged and
circulation is retained
The plate does not have to be precisely shaped to the bone to provide stability
Minimally invasive surgery (MIS): – The soft tissue and the wound
hematoma are treated gently – Circulation is maintained

LCP Locking Compression Plate Surgical Technique DePuy Synthes 3
Reduction maintained under a load LCP combi-hole
Stable bridging of comminuted fractures
The stable plate-screw connection decreases secondary loss of reduction in the epiphyseal and metaphyseal regions
The screws are locked in the plate, and the physiological load (F) is transferred from the bone to the plate
The fragments are fixed in their reduced position without regard to the plate model (internal fixator)
The bone fragments are fixed in the position assumed at the time the screws are locked
A Stable plate-screw connection – Locking screws reduce screw
loosening – Excessive torque is not applied to
the cortical bone – The conical screw head may help
to insert the screw
B Compatibility – The proven dynamic compression
hole allows the use of all standard (Cortex or Cancellous Bone) screws
Self-tapping locking screws
– Use after precisely measuring the length (metaphysis)
– Monocortical or bicortical use – Not necessary to separately tap
thread
Self-drilling locking screws
– Use without having to precisely measure the length (diaphysis)
– Only for monocortical use – Tapping and predrilling are
unnecessary
Standard (Cortex or Cancellous Bone) screws
– Dynamic compression is created by the eccentric insertion of the stan-dard screws (analogous to LC-DCP)
4 DePuy Synthes LCP Locking Compression Plate Surgical Technique
LCP Metaphyseal Plates. For extra-articular fractures.
LCP combi-holes allow uncompromising combinationsThe combi-hole allows an internal plate fixation using stan-dardscrews, angular stable locking screws, or a combination of both. This takes into account the most diverse intraopera-tive requirements.
Angular stability allows for improved fixationThe angle- and axis-stable locking screws may prevent loss of reduction under load. A precise anatomical contouring of the plate is unnecessary when using this system as a locking internal fixator.
Feasability of plate contouring due to thinned plate profileThe plate design facilitates anatomical contouring consider-ably, whilst taking into account the distinctive features of the metaphyseal bone area (e.g. complex bone shapes, thin soft tissue envelope).
Extra-articular fixation with the advantage of angled locking screwsThe two distal holes in the thinned area of the plate, which are angled at 11° towards the centre of the plate, may allow an application of the locking screws in the epiphyseal area.
Additional design features – Bullet nose plate tip for application of the minimally
invasive surgical technique. – Temporary fixation can be achieved through the
suture hole. – Improved vascularization of the periost due to plate
undercuts that reduce the plate-to-bone contact. – The elongated hole in the shaft are designed to allow
fine tuning of the reduction in the longitudinal axis.

6 DePuy Synthes LCP Locking Compression Plate Surgical Technique
Intended Use, Indications and Contraindications
Intended Use Locking Compression Plate (LCP) Implants are intended for temporary fixation, correction or stabilization of bones in various anatomical regions.
This Surgical Technique applies to the Depuy Synthes LCP Locking Compression Plate Systems and product lines listed below, which include but are not limited to the following indications:
IndicationsThe indications for each system will be presented individu-ally.
Small Fragment plates (3.5) LCP Plates 3.5Fixation of small bone fragments using the five standard AO plating principles (buttress plate, neutralization plate, tension band plate, bridge plate, compression plate).
LCP Reconstruction Plates 3.5Fixation of small bone fragments using the five standard AO plating principles (buttress plate, neutralization plate, tension band plate, bridge plate, compression plate).
LCP T-Plates 3.5Fixation of small bone fragments using the five standard AO plating principles (buttress plate, neutralization plate, tension band plate, bridge plate, compression plate). Fracture fixa-tion and fixation after osteotomies, malunions, non-unions; e.g. including but not limited to distal radius, proximal and distal tibia, proximal humerus, clavicular.
LCP Cloverleaf Plates 3.5 – For medial buttressing of comminuted distal tibial
fractures – For comminuted humeral head fractures
LCP One-third Tubular Plates 3.5 The LCP One-third Tubular Plates 3.5 are indicated for plating of fractures of long and small bones. The plate should only be used for load-sharing purposes, e.g. buttressing, tension banding, neutralization or compression.
LCP Methaphyseal 3.5The LCP Metaphyseal Plates are indicated to fix extra-articu-lar fractures in the metaphyseal area that can extend into the shaft area. The 3.5 mm plates are indicated to fix fractures of the distal humerus and distal fibula.
LCP Locking Compression Plate Surgical Technique DePuy Synthes 7
Large Fragment plates (4.5/5.0)LCP Methaphyseal 3.5/4.5/5.0The LCP Metaphyseal Plates are indicated for Extra-articular fractures of the metaphyseal area that extend into the shaft area.
The 4.5/5.0 plates are indicated to fix fractures of the proxi-mal humerus and distal tibial.
LCP 4.5/5.0 Narrow PlatesLCP T-Plates 4.5/5.0LCP 4.5/5.0 Broad PlatesLCP 4.5/5.0 Broad Curved PlatesLCP Reconstruction Plates 4.5/5.0LCP L-Buttress Plates 4.5/5.0LCP T-Buttress Plates 4.5/5.0
In general the LCP Generic Plates & Instruments (Large Frag-ment) are indicated for the osteosynthesis of fractures at the Femur, Tibia, Humerus and Pelvic at proximal, distal and shaft areas.
The existing designs of the Synthes of the large fragment plates (standard plates DCP, LC-DCP) have been retained. The same indications apply for LCP plates as for the correspond-ing standard plates.
In the case of metaphyseal fractures, comminuted fractures and osteoporotic bone, the clinical results can be improved by the angular stable screw/plate connection.
ContraindicationsNo specific contraindications.
8 DePuy Synthes LCP Locking Compression Plate Surgical Technique
Standard Plate Technique
1Reduce the fracture
Reduce the fracture under the image intensifier. As needed, provide fixation with Kirschner wire or reducing forceps.
AlternativeReduce the fracture indirectly using the plate by means of standard screws (for lag screw technique: to generate inter-fragmentary compression, use cancellous bone or cortical bone screws, see examples of the Combination Technique on page 36).
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.

Precisely contour the LCP plate to the anatomy using the appropriate bending instruments (as for standard plates), especially in the case of joint fractures.
Precautions: – Reverse bending or use of the incorrect instrumentation
for bending may weaken the plate and lead to premature plate failure (e.g. breakage). Do not bend the plate be-yond what is required to match the anatomy.
– Do not bend the plate at the level of the holes.
Note: The LCP combi-holes are asymmetrical in the plate. In straight plates, the hole alignment changes in the middle of the plate. This asymmetry enables unidirectional dynamic compression to be exerted.

Option: Insert a 2.7 mm cortex screw in a small fragment plate Place an LCP Washer 2.7/3.5 (X19.981) in the DC hole part of the 3.5 mm LCP plate. In this case, predrill with a Drill Bit with a 2.0 mm diameter (310.190).
Notes: – The holes in the straight LCP plates are larger at the two
ends to allow the insertion of cancellous bone screws. – If a combination of cortex and locking screws is used, a
cortex screw should be inserted first to generate interfrag-mentary compression.

1Reduce the fracture and preliminarily fix it
Reduce the fracture under the image intensifier, and fix it with Kirschner wires or reducing forceps.
2Bend the plate
Adapt the plate to the anatomy using the appropriate bending instruments. (See section 2 “Bend the plate” on page 9).
Precautions: – Reverse bending or use of the incorrect instrumentation
for bending may weaken the plate and lead to premature plate failure (e.g. breakage). Do not bend the plate be-yond what is required to match the anatomy.
– Do not bend the plate at the level of the holes.
3Position the plate and preliminarily fix it
Position the plate on the bone, and preliminarily fix it (for preliminary fixation using an LCP centering sleeve for Kirschner wires, see step 5).
Before setting the first locking screw, make sure that the plate is provisionally fixed well to prevent rotating since it could damage soft tissue when locking the screw.

Carefully screw the LCP drill sleeve into the desired LCP hole until it is gripped completely by the thread.
Precaution: The use of the LCP drill sleeve is mandatory in order to ensure that the locking screw is drilled in the proper perpendicular angle and correctly locked in the plate.
Notes: – To make it easier for the drill sleeve to grip the thread, it
may be useful to slightly rotate it to the left (back). – In the case of meta-epiphyseal plates, the threaded hole is
usually not perpendicular to the plate surface due to the anatomy.

Insert the centering sleeve for Kirschner wires into the LCP drill sleeve. To allow the locking screw alignment to be checked later, use a power tool to insert a Kirschner wire and check its position under the image intensifier (see sec-tion metaphyseal plates). This check is especially recom-mendable in the metaphyseal region. Remove the Kirschner wire and the centering sleeve for Kirschner wires.
Note: If the angle of the locking screw is not optimal, it can be corrected. Bend the plate as needed, or move it in a prox-imal or distal direction. This technique is also suitable to pre-liminarily fix the plate to the bone.

Before setting the first locking screw, anatomical reconstruc-tion must have occurred and, where necessary, fixed with lag screws. After setting the locking screws, additional re-duction can no longer occur without removing the locking screws. The locking screws can either be inserted with a power tool without locking or manually.
Warning: If a locking screw is used first, care should be taken to ensure that the plate is held securely to the bone to avoid spinning of the plate about the bone.
Insert Self-tapping Locking Screws
LCP Locking Compression Plate Surgical Technique DePuy Synthes 21
a. Insertion with a power toolTo insert the locking screw using a power tool, fit a torque limiter to the power tool. Then insert the screwdriver shaft into the torque limiter.
Pick up the locking screw and insert it into the plate hole. To insert the screw, start the power tool slowly, increase the speed and then reduce it again before the screw is fully tightened. Uncouple the power tool, and mount the handle with the CAD coupling or the handle with the quick cou-pling, and manually tighten the screw. After one click, the optimum torque is reached.
Warning: Locking screws may be partially inserted using power equipment alone. However, always use a torque limit-ing attachment (TLA) when using power to insert locking screws.
Note: Do not lock the screws at full speed to reduce the risk of stripping the head. This can make it difficult to remove the implant.
Precaution: For long screws and thick cortical bone, ensure sufficient cooling during insertion.

1Preliminary fixation
Provisionally fix the LCP locking plate to the bone.
Note: The self-drilling screws are primarily inserted in bone regions where a precise determination of length is not re-quired (diaphysis). They can only be set monocortically.
Precaution: Do not insert the drill tip into the opposite cor-tical bone to prevent damage of the opposite side structure and to avoid removal problems.

Stop the power tool before the screw is locked. Remove the power tool and mount the handle. Lock the screw and tighten it until a click can be heard.
Notes: – Especially when the cortical bone is thick and the locking
screw is set perpendicular, drilling with the LCP Universal Drill Guide (small fragment: 323.505; large fragment: 323.500) is recommended. The universal drill guide is also used when inserting self-tapping screws in the diaphyseal region. For further information, see page 29.
– You can alternatively follow steps 4–7 on pages 16–19.
Precaution: Always irrigate during drilling to avoid thermal damage to the bone. Cooling is especially recommended for longer screws.

Insert Kirschner wires to determine the direction of the screws or to temporarily fix the plate using the centering sleeve for Kirschner wires.
Verify the Kirschner wire position under the image intensi-fier.
The simultaneous use of two threaded LCP drill sleeves in the thinned plate area also assists insertion in the minimally inva-sive surgical tech nique.
Note: For patient positioning and surgical approach refer for example to Rüedi TP, Buckley RE, Moran CG (2007) AO Principles of Fracture Management. 2nd expanded ed. 2002. Stuttgart, New York: Thieme.
Warning: Do not position the thinner portion of the plate over the fracture site.

Examples of the Combination Technique
Standard screws and angular-stable locking screws can be combined.
Example AIf a plate is first fixed with standard screws (1), locking screws can be introduced later (2) to fix the fragments at a stable angle.
Example BIf a plate is first fixed to a fragment with locking screws (1), do not insert standard screw afterwards in the same frag-ment (2). In this case, the locking screws must be removed first before inserting the standard screws.
Example CIf the metaphyseal fragment is fixed with locking screws (1), the fracture can be dynamically compressed with standard screws (2). To increase the stability of fixation, insert addi-tional locking screws into the diaphyseal fragment (3).
Example DIn the case of a diaphyseal fracture, standard screws can be inserted after the locking screws to draw the opposing frag-ments closer to the plate.

Remove the Implant
Implant RemovalUnlock all screws from the plate, then remove the screws completely from the bone. This prevents simultaneous rota-tion of the plate when unlocking the last locking screw.
For details regarding implant removal refer to the Surgical Technique “Screw Extraction Set” DSEM/TRM/0614/0104.

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.
