INDICATIONS
The 2.7 mm LCP® Ulna Osteotomy System is indicated for fixation of fractures, osteotomies, nonunions, replantations, and fusions of small bones and small bone fragments, including osteopenic bone, in the ulna. The 2.7 mm LCP Ulna Osteotomy System is indicated for use in both adults and adolescents (12-21 years) in which growth plates have fused, or in which growth plates will not be crossed by screw fixation.

PREPARATION
1Preoperative planning
Complete preoperative radiographic assessment andpreoperative planning is essential, especially in cases ofsecondary impaction.
Contralateral x-rays allow determination of the necessaryamount of shortening.
The 2.7 mm LCP Ulna Osteotomy Plate is intended to be placed on the volar flat surface of the ulna, just proximal to the pronator quadratus muscle. It is recommended to place the plate between the distal and the middle third of the ulnar shaft.
Alternative plate placement, i.e. on the dorsal aspect, is also possible.
The plate may be contoured for proper placement on the bone. To preserve the strength of the plate, avoid repetitive bending.

2Approach
Make a longitudinal incision to approach the volar side of the ulna.
Precaution: Take care not to damage the dorsal sensory branch of the ulnar nerve.
PATIENT POSITION AND APPROACH
1Position patient
Place the patient in a supine position with the forearm positioned on a hand table in full supination and the shoulder in 90° abduction. The use of a tourniquet and magnifying loops is recommended.

Instruments
02.111.902.01 2.0 mm Kirschner Wire, with drill tip, 100 mm

Choose the appropriate drill template according to the intended amount of shortening.
Position the drill template on the bone and fix it bicortically with the 2.0 mm Kirschner wires with drill tip. Two lengths of Kirschner wires are available. For the fixation of the drill template at both ends, start distally and use 100 mm Kirschner wires (02.111.902.01 ➊ ➋) to avoid space constraints when inserting the third, 150 mm Kirschner wire (02.111.903.01 ➌).
The circular laser markings on the Kirschner wires can be used as a guide for insertion depth: the first marking indicates insertion depth of 10 mm, the second marking indicates 15 mm (reading at the edge of the drill template).
Precaution: Do not start drilling before Kirschner wire tip is in contact with the bone. Avoid off-axis insertion of the Kirschner wire.

Notes • Make sure the drill template is correctly oriented
proximally and distally according to the etchings.• The shape of the drill template is identical to the
shape of the 6-hole 2.7 mm LCP Ulna Osteotomy Plate (02.111.900/04.111.900).
• Ensure that the drill template lies centrally on the bone for proper plate placement.
• Confirm the placement of the drill template under imaging.
• Both ends of the drill template should sit flush on the bone when inserting the Kirschner wires. Otherwise, the plate may need to be bent to fit the patient’s anatomy.
• In case the ulnar bone is slightly convex, the drill template may not sit flush on the bone and could tilt. If the template is tilting, ensure that the distal end is kept flush on the bone when inserting the Kirschner wires.

If additional stabilization is desired, apply the compression/distraction instrument prior to performing the osteotomy cut.
Notes• Before using the compression/distraction instrument,
ensure that the screw nuts are loosened.• Be sure that the Kirschner wires used for fixation
of the compression/distraction instrument do not collide with the wires used for fixation of the drill template.
Position and fix the compression/distraction instrument with the 100 mm 2.0 mm Kirschner wires (02.111.902.01) in the inner part of the clamps (A). Tighten the nuts clockwise to retain the Kirschner wires.➊ For additional fragment support and rotational control, insert the 150 mm 2.0 mm Kirschner wires (02.111.903.01) in the outer part of the clamps (B).
Notes• Both tips of the compression/distraction instrument
should be in contact with the bone.• Adjust the position of the clamps to allow for
adequate working space by turning the spindle.➋

For an oblique cut, it might be necessary to remove the saw guide to apply the compression/distraction instrument. The cut can be marked before the compression/distraction instrument is applied.
The circular laser markings on the Kirschner wires can be used as approximate indication for insertion depth: the first marking indicates insertion depth 10 mm, the second marking 15 mm (reading at the cut-out edge of the compression/distraction instrument).
Perform the osteotomy cut. If more workspace is needed, the compression/distraction instrument can be positioned further away from the bone. For proper alignment, check exact position prior to moving the compression/distraction instrument.
After removal of the drill template, distract/reduce the bone ends by turning the knob on the spindle. Distraction might be helpful to check for bone residues that could impede complete closure of the gap.

Choose an appropriate parallel saw blade for transverse osteotomy (90°) and intended amount of shortening. Be sure that the parallel saw blade and the drill template are intended for the same amount of shortening. Before starting the osteotomy, ensure that the parallel saw blade spacer is in the correct position, away from the coupling part.
Precautions• Protect the soft tissue behind the far cortex.• Avoid applying excessive force while making the
osteotomy cut.• Always irrigate during sawing to avoid excessive
heating. During use, excessive heating can lead to thermal necrosis of the bone of soft tissue burns.
• Make sure that the cut is always perpendicular to the long axis of the bone.
Align the parallel saw blade with the transverse parallel markings on the drill template and perform the osteotomy cut. The markings on the drill template indicate the correct positioning of the saw blade.
Perform the osteotomy with the drill template in contactwith the bone and the parallel saw blade in motion. Do not shift the direction of the saw blade once cut has been started. Once cutting has been started, advancement of the saw blade may be easier when the drill template is slid away from the bone by 2-3 mm.

Attach the saw guide to the drill template (1).
Precautions:• To indicate the correct angle for the 45° oblique cut, a
saw guide can be mounted on the drill template (1).• Make sure that the cut is always perpendicular to the
long axis of the bone.• Protect the soft tissue behind the far cortex.• Avoid applying excessive force while making the

Use the 0.8 Nm torque limiting attachment (TLA) for final tightening of the 2.7 mm locking screws
The TLA attaches to the blue handle for torque limiters and a StarDrive T8 Screwdriver Shaft.
The TLA ensures consistent insertion torque to provide uniform plate-screw interface and prevents overtightening of the locking screws. With this final locking step, the screws are securely locked into the plate.
Note: When performing the final locking step, the TLA should always be used.
If the torque limiter releases prior to final locking, the use of a tap is recommended.
* Recalibration of the torque limiter: DePuy Synthes Companies recommends annual servicing and inspection by the original manufacturer. The torque limiter has to be sent to your DePuy Synthes Companies repair center annually for calibration. The user accepts the responsibility for this annual calibration.
