Preoperative Planning
Use the AO preoperative planner templates for the Expert Adolescent Lateral Femoral Nail (034.000.600/605) to estimate nail length and medullary canal diameter.
To estimate medullary canal diameter, place the template on the AP or lateral x-ray of the femur and measure the dia-meter of the medullary canal at the narrowest part that will contain the nail.
To estimate nail length, place the template on the AP x-ray of the uninjured femur and select the appropriate nail length based on patient anatomy. When selecting nail size, consider canal diameter, fracture pattern, patient anatomy and post-operative protocol.
Note: Templates are available in two sizes: actual size and 115% magnification in which the image is enlarged 15% to correspond to typical radiographic magnification; however, variations in magnification levels are common.

1Position patient
Position the patient in the lateral decubitus or supine position on a fracture table or radiolucent operating table. Position the C-arm to allow visualization of the proximal femur in both the AP and lateral planes.
To facilitate access to the medullary canal, abduct the upper part of the body approximately 10°–15° to the contralateral side and adduct the affected limb by 10°–15°.
Expert ALFN Surgical Technique DePuy Synthes 11
2Reduce fracture
Perform closed reduction manually by axial traction under image intensifier control. The use of the large distractor may be appropriate in certain circumstances (refer to the surgical technique 036.000.038).
3Confirm nail length
Instrument
03.010.020 Radiographic Ruler for Expert Femoral Nails
The required nail length must be determined after reduction of the femoral fracture.
Position the C-arm for an AP view of the proximal femur. With long forceps, hold the ruler alongside the lateral thigh, parallel to and at the same level as the femur. Adjust the ruler until the proximal end is at the desired nail insertion.
12 DePuy Synthes Expert ALFN Surgical Technique
Preoperative Planning
Move the C-arm to the distal femur. Verify fracture reduction. Align the proximal end of the radiographic ruler to the skin mark, and take an AP image of the distal femur.
Read nail length directly from the ruler image, selecting the measurement proximal to the epiphysis, or at the chosen insertion depth.
Notes: � It is recommended to treat the fracture with the longest nail possible without crossing the physis, taking into account patient anatomy or a previous implant. The distal end of the nail should be 15 mm from the physis.
� Compression (with the conventional backstroke technique) or dynamization must be taken into account when determining the nail length. A shorter nail should be chosen when back hammer ing or dynamization is planned for the procedure (the dynamic slot allows for 7 mm of movement).
4Confirm canal diameter
Instrument
03.010.023 Radiographic Ruler for Nail Diameters for Expert Femoral Nails, length 365 mm
The required nail length must be determined after reduction of the femoral fracture.
Position the C-arm for an AP or lateral view of the femur at the level of the isthmus. Hold the radiographic canal width estimator over the femur with the diameter gauge centered over the narrowest part of the medullary canal. Read the estimated diameter measurement on the circular indicator that fills the canal.
Notes: � If the reamed technique is used, the diameter of the largest medullary reamer must be at least 1.0 mm greater than the nail diameter.
� The ruler provides only an estimate of the canal diameter as it is not at the same level as the femur.

1Approach
Palpate the posterior edge of the greater trochanter.
Make a 3 cm incision in line with the central axis of the intramedullary canal in the lateral view, and depending on the anatomy of the patient, 2–5 cm proximal to the tip of the greater trochanter.
Opening the Femur
2Determine entry point
The insertion point is 12° lateral to the greater trochanter, as measured from a point 20 mm distal to the lesser trochanter.
The entry point can also be described as lateral to the greater trochanter at the same level as the superior aspect of the base of the femoral neck (just above the piriformis fossa). This point can be found by extending a line horizontally from the base of the femoral neck to the lateral side of the femur.
Note: To ensure a correct entry point the preoperative planner template for the ALFN can be used.

Insert the protection sleeve, wire guide and trocar assembly into the incision site and to the bone.
Remove the trocar. Insert the guide wire through the wire guide.
The guide wire must be inserted laterally at an angle of 12° to the center of the medullary canal. The tip of the guide wire should be centered in the medullary canal 20 mm distal to the lesser trochanter.
Verify that the guide wire position allows adequate clearance on the lateral side of the femur for the opening drill bit.
The guide wire is inserted with it centered in the lateral view.
Precaution: The correct entry point and angle are essential for a successful result. To ensure the correct position of the guide wire, hold a sterile Adolescent Lateral Femoral Nail onto the femur and check radiographically.

5Ream medullary canal (optional)
Instrument
03.010.093 Rod Pusher for Reaming Rod with Hexagonal Screwdriver B 8.0 mm
Note: For the detailed reaming procedure, please consult SynReam Surgical Technique.
If necessary, use a reaming system intended for femur ream-ing procedures to enlarge the medullary femoral canal to the desired diameter.
Check fracture reduction under image intensifier.
Insert reaming rodInsert a 2.5 mm reaming rod into the medullary canal until the desired insertion depth. The tip must be correctly positioned in the medullary canal since it determines the final distal position of the Expert ALFN. The use of the Reduction Instrument for Medullary Nails may be helpful in certain circumstances.
ReamingStarting with the smallest diameter reaming head, ream to a diameter of 0.5 to 1.5 mm greater than the nail dia meter. Ream in 0.5 mm increments and advance the reamer with steady, moderate pressure. Do not force the reamer. Partially retract the reamer repeatedly to clear debris from the medul-lary canal.
Use the holding forceps to retain the reaming rod while reaming and to prevent it from rotating.

Inserting the Nail
Expert ALFN Surgical Technique DePuy Synthes 21
Slide the connector into the groove on the insertion handle and secure it using the 11 mm ratchet wrench. If patient anatomy allows, attach the driving cap in the medial position.
Orient the insertion handle in an anterior position. Use the C-arm to verify fracture reduction. Insert the nail as far as possible.
The nail rotates approximately 90° during insertion. The insertion handle rotates from an anterior to a lateral po-sition during insertion of the last one-third of the nail length. If the nail does not rotate to the lateral position, remove the nail and reinsert it with the handle slightly lateral to the sagittal plane.
Monitor nail passage across the fracture, and control in two planes to avoid malalignment.
22 DePuy Synthes Expert ALFN Surgical Technique
If desired, insert the nail using light hammer blows.
Lock the head of the hammer in place by tightening the nut onto the threads located below the hammer head. Use the pin wrench if necessary. Strike the driving cap directly.
Optionally, the hammer guide can be threaded onto the driving cap and the hammer can be used as a slide hammer. Loosen the nut from the threads located below the hammer head and secure the nut onto the threads located above the handle.
Precautions: � Do not mount the aiming arm until the nail has been completely inserted.
� If nail insertion is difficult, choose a smaller diameter nail or ream the intramedullary canal to a larger diameter.
� Do not hammer directly onto the insertion handle. Retighten and confirm that the nail is securely connected to the insertion handle.
Inserting the Nail
Expert ALFN Surgical Technique DePuy Synthes 23
3Check proximal nail position
Insert the nail until it is at or below the femoral opening.Check final nail position under image intensification in AP and lateral views.
If primary compression or secondary dynamization is planned, it is recommended to overinsert the nail by more than 7 mm, which corresponds to the maximum distance between the positions in static and dynamic modes.
Note: The distance between the markings on the insertion handle is 5 mm and corresponds to the extensions of the end caps. This feature can be used for overinsertion of the nail.
4Check distal nail location
Use image intensification to ensure the nail is centered in both AP and lateral views. Verify fracture alignment.
Remove the reaming rod.

Insert the locking screw using the screwdriver, and the holding sleeve with locking device, if desired.
Verify locking screw length under image intensification. The screw tip should be about 2 mm beyond the far cortex. If needed, a second locking screw may be inserted using the same technique.
Use the holding sleeve as described below: Insert the holding sleeve onto the shaft of the screwdriver and place the tip of the screwdriver in the recess of the locking screw (Figure 1).
Push the holding sleeve in the direction of the locking screw. The sleeve now holds the locking screw.
Lock the holding sleeve by tightening it counterclockwise (Figure 2). After insertion of the locking screw, release the holding sleeve by loosening it clockwise and pulling it back (Figure 3).
Read the locking screw length directly from the depth gauge at the back of the outer sleeve.
Note: In the event of a diastasis, the backstroke technique can be used after insertion of the second distal locking screw.

Choose an end cap with the appropriate extension; 0 mm if the nail is not overinserted, 5 mm, 10 mm or 15 mm if the nail is overinserted.
The end caps are cannulated for use over a guide wire, if necessary.
Note: End caps fulfill two functions: they prevent bone ingrowth into the nail; and they extend the nail height if it is overinserted.
Remove the nail insertion instruments.
Optionally, for insertion of the 0 mm end cap, remove the connecting screw only. The insertion handle can r emain to help align the end cap to the top of the nail. The 0 mm end cap fits through the barrel of the insertion handle.
Insert the guide wire into the proximal end of the nail.
Engage the end cap with the cannulated screwdriver by exerting axial pressure. To prevent cross-threading, align the end cap with the nail axis and turn the end cap counter-clockwise, until the thread of the end cap aligns with that of the nail.
Turn the end cap clockwise to thread the end cap into the nail.
Remove the guide wire and screwdriver.

Aiming Arm (03.010.483)
– Easy snap-on and snap-off mechanism – “Friction” and “True locking” – Backward compatible with existing devices – Radiolucent – More soft tissue clearance – Easy disassembly for cleaning
1. Some force is required to push the cam lock mechanism over the wings.
2. To fi x the cam lock mechanism at the corresponding pins, the cam lock must be pushed back in open position.
Scalpel Handle (03.010.491)
– For channel cutting to minimize muscle force on the protection sleeves
– Yellow Silicon handle indicates sharpness of instrument
1. Attach a blade to the scalpel holding the end of the handle.
Insertion Handle (03.010.488)
– Radiolucent – Attachment for driving cap with threaded end
(03.010.523)
InterLock ScrewdriverCompatible with all Synthes T25 or 3.5 mm hexagonal re-cess. For further information, please refer to brochure 036.001.581.
– Tear drop shape – Silicon handle
Precaution: When removing implants after longterm implantation, especially in the presence of large amounts of bony ingrowth, fi rst use a solid screw-driver to loosen the screw. The interlock screwdriver
can then be used to remove the screw from the surgical site. If using the interlock screwdriver with locking screws, use a solid screwdriver for fi nal tightening.
2. Pass the scalpel handle through the aiming arm holes and perform a minimally invasive and accurate incision.
3. Remove the scalpel from the aiming arm.

Set ListModular Cases
The modularity of the system enables sets to be confi gured according to the hospital’s clinical needs. Each set confi gu-ration consists of basic instruments, dedicated system instru-ments and optional instruments (if required). For femoral nails (LFN, ALFN, R/AFN) the femur set must be added to the set confi guration. New modular trays also contain the ASLS instruments. For further information about ASLS refer to pages 77 and 78.
The instrument modules listed on the right side are available.
For ease of use within the operating theatre, all modular trays have an additional marking: – Mandatory modular trays have a solid white marking – Optional trays have a hatched black marking – Each system has a control picture for reference

What is ASLS?The Angular Stable Locking System (ASLS) provides the abil-ity to create a fixed-angle construct to an intrame dullary nail. Therefore, it combines the advantages of angular stability and a minimally invasive approach. ASLS together with an intramedullary nail form the principle of the Intramedullary Fixator.
Optional: Angular Stable Locking System (ASLS)
The following description contains general information about ASLS. For further details on the application and compatibility of ASLS please refer to the Surgical Technique 036.000.708.
How does ASLS work?The system consists of a screw with three outer diameters and a resorbable sleeve.
The resorbable sleeve is placed on the screw tip which has the smallest screw diameter and is pushed into the locking hole of the nail.
During screw advancement, the resorbable sleeve is ex-panded by the larger middle diameter. Radial expansion of the sleeve and its fixation in the nail creates the angular stability.

MRI Information
Torque, Displacement and Image Artifacts according to ASTM F 221306, ASTM F 205206e1 and ASTM F211907Non-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.
RadioFrequency(RF)induced heating according to ASTM F218211aNon-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.
