LCP Pediatric Hip Plate System

2 DePuy Synthes LCP Pediatric Hip Plate 2.7 Technique Guide

The LCP Pediatric Hip Plates are an innovative concept con-sisting of the LCP Pediatric Hip Plates 2.7, 3.5 and 5.0.

LCP Pediatric Hip Plates cover treatment options for stable fixation of varus and valgus deformities as well as rotationosteotomies and proximal femoral fracture treatment.

The highly successful Locking Compression Plate (LCP) tech-nology, which has enjoyed great success in adult surgery overrecent years, has been incorporated into this system dedi-cated to pediatrics.

For more information about the available plate sizes andtheir corresponding screw angles, please refer to page 36.

In comparison to conventional blade/plate systems, the LCPPediatric Hip Plates have four main advantages:

Angular stabilityReduces the risk of primary and secondary loss of correction.In the majority of cases involving older pediatric patients ex-ternal splintage is no longer necessary. For the LCP PediatricHip Plate 2.7, external splintage, such as a spica, is recom-mended as the plate is small and the infant non-compliant.

Easy and safe surgical techniqueInitial plate positioning with Kirschner wires rather than using a chisel allows easy adjustment with less bone damage.

MedializationFor LCP Pediatric Hip Plates 3.5 and 5.0 there is the possibil-ity of additional medialization, which means that just oneoff-set is required for each plate size.

Low profileThe low profile plate design and locking construct allow lessmuscle disruption and reduce the risk of soft tissue irritation.

LCP Pediatric Hip Plate SystemThe LCP Pediatric Hip Plates have a universal design for theleft and right femur. They have the following main character-istics, which ensure excellent fixation in the bone:– LCP Pediatric Hip Plates 3.5 and 5.0 have three neck

screws in the proximal part and combi-holes for locking orcortex screws in the distal part

– LCP Pediatric Hip Plate 2.7 has two neck screws in theproximal part and combi-holes for locking or cortexscrews in the distal part

Valgus plate 5.0

Features and Benefits

AO Principles

Stable fixationThe fixation of the LCP plate with angular stable screws re-duces the risk of loss of correction in osteotomies intra- andpostoperatively.

Preservation of blood supplyThe features of the child periosteum allow blood supply tobe preserved even if the periosteum is elevated.

Early mobilizationThe use of LCP implants allows an early and active mobiliza-tion, including cast-free postoperative management (Pediatric Hip Plates 3.5 and 5.0) in younger and handicappedchildren where appropriate. For the LCP Pediatric Hip Plate2.7, external splintage, such as a spica, is recommended asthe plate is small and the infant non-compliant.

Foreword

For many years, the angled blade plates, devised by Dr Müller,were the standard implants used by the AO school of surgeons. They combine implant strength with an excellenthold in the bone but some surgeons have found them difficult to insert.

The LCP Pediatric Hip Plate 2.7 is versatile, easy to insert andreproduces the strength and hold of the angled blade plates.Proximal screw placement is always preceded by guide wireinsertion while locking screws provide the necessary rigidity.External splintage, such as a spica, is recommended as theplate is small and the infant non-compliant.

This surgical technique describes the steps and principles in-volved when using the LCP Pediatric Hip Plate 2.7 to performa typical varus osteotomy in combination with external or in-ternal rotation. Further, the flexibility of the system allowsthe surgeon to adapt the osteotomy to the patient.

LCP Pediatric Hip Plate 2.7 Technique Guide DePuy Synthes 5

Indications

The LCP Pediatric Hip Plate system consists of indication spe-cific plates. This surgical technique focuses on the LCP Pedi-atric Hip Plate 2.7 and describes a varus osteotomy of theproximal femur.

The LCP Pediatric Hip Plate 2.7 is intended for use in infantsup to three years, depending on body weight and bone qual-ity.

Indications:– Neglected dislocation of the hip in combination with open

reduction– Developmental coxa valga– Severe hip dysplasia

Important: Ensure that the plate selected has a neck/screw angle which corresponds to preoperative planning.

Case 2*

18 month old girl with neglected dislocation of the left hip.The left hip had a 150° preoperative CCD angle. An open re-duction was performed in combination with an inter-trochanteric osteotomy, which reduced the CCD angle to115° (34° correction angle) in combination with 30° externalrotation correction. The osteotomy was fixed using a LCP Pe-diatric Hip Plate 2.7, 110°.

Postoperative x-rays show good correction and centralizationof the hip in AP and lateral views.

6 weeks postoperative follow-up shows no loss of reduction,no plate or screw loosening and good callus formation.

11Determine correction anglePreoperative planning is vital for proximal femoral osteo -tomies. Although there are different ways of planning, theyare all designed to achieve the same result.

The first step is to decide on the desired final position afterosteotomy, in particular the neck/shaft angle that is to beachieved.

Options:1) Take an AP pelvis x-ray (1).2) Take an AP pelvis x-ray in abduction and with internal rota-

tion to assess the cover (2).3) Create a blueprint to assess the correction that will

achieve cover. (3)4) Choose a target neck/shaft angle based on the patient’s

pathology (4).

2Select plateThe angle of the plate should be close to that of the desiredneck/shaft angle. The offset of the 100° and 110° LCP Pedi-atric Hip Plates for varus deformities makes them ideal forvarus osteotomies.

Preoperative Planning

LCP Pediatric Hip Plate 2.7 Technique Guide DePuy Synthes 9

3Determine point of reference

The femoral shaft or neck can be used as a reference whileplanning and later inserting the positioning Kirschner wire.

a) Shaft referencingTo calculate the correction angle, subtract the desiredneck/shaft angle from the initial pathological neck/shaft angle.

For example:Current pathological neck/shaft angle: 150°Desired neck/shaft angle: 120°Correction angle: 30°

To calculate the insertion angle of the positioning Kirschnerwire using the aiming block and the positioner for aimingblock on the shaft, add together the newly calculated correc-tion angle and the plate angle.

For example:110° Plate angle + 30° correction angle = 140°Insert positioning Kirschner wire at 140° to the shaft

b) Neck referencingThe positioning Kirschner wire is inserted at an angle to thefemoral neck. To calculate the insertion angle of the position-ing Kirschner wire using the aiming block and positioner foraiming block, subtract the plate angle from the desiredneck/shaft angle.

For example:Desired neck/shaft angle: 130°Plate angle: 110°Insert positioning Kirschner wire at 20° to the femoral neck

3The wing of the positioner for aiming block must be placedparallel to the proximal femoral shaft in AP and lateral view.The positioner for aiming block and the two front spikes ofthe aiming block must be in contact with the femur (3).

The entry points for the positioning Kirschner wires are10 –15 mm distal to the trochanteric epiphysis in AP view.

Note: If there is extreme coxa valga, the positioner for aim-ing block must be placed more distally to prevent the neckscrew from perforating the piriformis fossa.

Insert the positioning Kirschner wires in holes C and D paral-lel to the anteversion Kirschner wire in the lateral/axial view,such that they define the middle third of the femoral neck (4).

Begin with the posterior positioning Kirschner wire to avoidinterference with the anteversion wire (5). Once this wire isin place the anteversion wire can be removed. Then insertthe positioning Kirschner wire in the anterior hole (6).

To avoid slippage of the positioner for aiming block, do notremove the positioning Kirschner wires until the top neckscrew is in place.

All subsequent steps refer to the positioning Kirschner wires,therefore their exact position is crucial.

Tip: Use the 230 mm wire to reduce the risk of interferencewith the power tool.

Tip: To facilitate insertion, center-punch the surface of thebone at the entry point before inserting positioner and wire.

Note: Do not bend the Kirschner wires during insertion asthis may result in correction errors. This can occur when flex-ing the hip in lateral/axial view.

Note: If extension or flexion is required at the osteotomy, theaiming block for screws with the positioner for aiming blockhas to be rotated accordingly before insertion of the secondpositioning Kirschner wire.

Once the Kirschner guide wire has been correctly inserted inhole A, remove the positioner for aiming block and the aimingblock. The Kirschner guide wire defines the position andlength of the screw and predrills the hole for the 2.7 mmscrews.

Note: Avoid bending the positioning Kirschner wire with theaiming block while inserting the guide wire as this may resultin correction mistakes.

Tip: To remove the positioner for aiming block and the aimingblock, loosen the Stardrive screw on the positioner for aim-ing block.

Instrument

03.108.039 Positioner for Osteotomy, for LCP Pediatric Hip Plates 2.7

The optimal position of the osteotomy for the 2.7 mm plateis 9 mm distal to the positioning Kirschner wires in holes Cand D. Determine the distance with the corresponding endof the positioner for osteotomy (1). Hold the positioner forosteotomy against the positioning Kirschner wires and markthe distance with the oscillating saw or another sharp instru-ment on the bone (2).

Note: Prior to cutting the osteotomy insert Kirschner wiresinto the greater trochanter and the distal fragment (eitherthe shaft or the knee) to control the rotation. Even if no rota-tion is planned, it is recommended to insert the twoKirschner wires or to make a mark on the bone. This ensuresthat rotational alignment is not lost.

Perform the osteotomy in one cut perpendicular to thefemoral shaft with an oscillating saw (3). Use constant irriga-tion and cooling.

Note: If there is extreme coxa valga, the osteotomy cut hasto be 3 – 4 mm further distal, otherwise the distance for thecalcar screw is too short.

Fixation in the proximal neck/head fragment must always beperformed with locking screws. Ensure that the lockingscrews are at least 5 mm away from the growth plate of thefemoral head.

Insert the drill sleeve into hole A. Tighten the drill sleeve withthe wrench for the positioner for osteotomy (2). Slide theplate over the two Kirschner wires (1).

Note: If the plate stands off the proximal fragment too much,remove a small bone wedge from the lateral cortex near theosteotomy.

Tip: Hold the femoral neck/head fragment with forceps tak-ing care not to disturb the plate positioning or manipulatethe Kirschner wires. This provides better handling of theproximal fragment and greater rotational stability (3).

For optimal fixation, the plate must be aligned parallel withthe femoral shaft axis in AP and lateral views. Once the plateis aligned, secure it with the reduction forceps.

Important: If the plate is not aligned parallel to the femoralshaft axis in AP view, it can lead to variations of the plannedneck/shaft CCD angle.

Tip: The alignment can be facilitated with forceps fixed onthe proximal part. This serves as a handle during the reposi-tioning of the osteotomy.

The LCP Pediatric Hip Plate 2.7 is a combi-hole plate, there-fore either locking or cortex screws can be used in the shaft.

Screw the LCP drill sleeve into the LCP portion of hole 1 untilit is completely gripped by the thread. Drill the screw hole us-ing the drill bit � 2.0 mm (1). Remove the drill sleeve. Determine the screw length with the depth gauge and insertthe screw.

Repeat this step for screw insertion in hole 2 (2).

Note: When cortex screws � 2.7 mm are inserted, the uni-versal drill guide 2.7 can be used. Drill threaded holes withthe drill bit � 2.0 mm and measure the screw length withthe depth gauge.

Note: Cortical screws cannot safely be inserted after a lock-ing screw has been used in the distal fragment.

Distal Fixation

LCP Pediatric Hip Plate 2.7 Technique Guide DePuy Synthes 27

External splintage, such as a spica, is recommended as theplate is small and the infant non-compliant. Frequently thisplate will be used in combination with other procedures thatrequire immobilization, such as open fracture reduction.

Note: A hip spica in abduction allows a release of stress onthe muscles.
