Porous coating — ROUGHCOAT™ porous coating is intended to increase the friction between the implant and bone, improving implant stability and providing a porous surface for bone ingrowth.

Driving platform — The ECHELON™ implants feature a threaded driving platform with an elliptical slot for rotational and axial implant control during insertion.

Neck geometry — Circulotrapezoidal neck provides increased range of motion compared to a circular neck of the same strength.

Collar options — A standard collar and +15mm calcar platform are available to match the implant to the proximal defect.

Distal slot — The distal slot eases stem insertion, reduces the risk of fracture,1 and reduces distal stem stiffness.

Hydroxyapatite — A 50 micron layer of hydroxyapatite is applied to the fully porous coated stem.

Shoulder relief — The lateral shoulder is rounded to minimize the risk of fracturing the greater trochanter during stem insertion.

Lateral proximal flare — The ECHELON system has a 3° proximal anterior/posterior flare to improve proximal fill, without preventing implant seating.

Distal flutes — The ECHELON system offers distal flutes to increase rotational stability.

Distal bullet tip — The bullet tip is intended to reduce the stress between the distal implant tip and the bone to minimize thigh pain.

Size range — The ECHELON system porous stems are offered in 1mm increments to minimize bone removal and provide optimum canal fill.

Preoperative planning and templatingThe general principles of patient selection and sound surgical judgment apply. The correct selection of the implant is very important. The appropriate type and size should be selected for patients with consideration of anatomical and biomechanical factors such as patient age, activity levels, weight, bone and muscle conditions, prior surgery and anticipated future surgeries, etc. Generally, the largest cross-section component which will allow adequate bone support to be maintained is preferred. Literature has shown a higher likelihood of revision in younger, heavier, or more active patients. Specifically, the risk of complication is greater in obese and morbidly obese patients. Failure to use the optimum-sized component may result in loosening, bending, cracking, or failure of the component and/or bone, resulting in revision surgery.

Preoperative planning for a revision total hip arthroplasty is the first, and most important step, requiring at a minimum a standard set of radiographs, which includes an antero-posterior (A-P) radiograph of the pelvis and a lateral radiograph of the affected hip. Depending on the length of the existing femoral component several additional radiographs may be necessary. Specifically, the A-P and lateral radiographs should include the entire femoral component. On occasion a full length A-P radiograph of the entire femur may be necessary. As part of the preoperative work-up, the surgeon may consider other imaging modalities such as bone scans and computerized tomography (CT). However, these are typically not necessary for preoperative planning.

Determine the appropriate classification for the femoral revision, for example, the Paprosky Revision Classification.1 This will aid in determining the appropriate type, size and position of the revision stem you will need.

As with primary THA preoperative planning, establishing proper leg length requires assessment of a number of clinical and radiographic parameters. Establishing the proper reference lines requires using a horizontal line between the inferior portion of the teardrop as well as a horizontal line between the inferior margin of the obturator foramen and ischial tuberosity. Due to the often distorted anatomy of revision cases, utilizing all three reference lines may be necessary.

Similarly, due to bony defects on the femoral side, a combination of anatomic landmarks such as the superior margin of the greater trochanter and inferior margin of the lesser trochanter must be utilized. These obviously need to be compared to similar points on the contralateral compared to similar points on the contralateral side using the A-P radiograph.

1 Paprosky W, Aribindi R. Hip replacement: treatment of femoral bone loss using distal bypass fixation. Instr Course Lect 2000; 49:119-130.

Any pelvic obliquities and/or spinal deformities must also be taken into account based on radiographic and clinical assessments. The consideration of all relevant factors is necessary to successfully restore the patient’s proper leg length.

Surgeon tip The use of simple wooden blocks during the preoperative physical examination of the patient is very useful, as is a discussion of the patient’s perceived length elicited during their preoperative interview.

The A-P radiograph is also critical in assessing proper femoral offset. If there is a native hip on the contralateral side, the proper offset can be determined by the horizontal distance between the center of rotation of the head and the anatomic axis of the femur. If there is a well-functioning total hip prosthesis on the contralateral side, a similar assessment can be made using the ECHELON™ templates. Templates are available in digital and acetate formats. Consult your Smith & Nephew representative for assistance in obtaining templates.

Difficulties sometimes arise when the contralateral hip is deformed or has a malfunctioning THA. Additional problems may be encountered if the ipsilateral acetabulum has failed or has a protrusion deformity. In these cases it is up to the surgeon to determine intraoperatively what the proper offset should be so as to achieve a hip that is without impingement in all physiological positions.

Once the bone stock has been assessed and proper leg length and offset have been established the surgeon should template the femur to determine the appropriate stem type, length and size. Stem length will be based on the amount of bone loss. Stable fixation may be obtained with 4 to 5cm of “scratch fit”.2

Porous-coated implant surgical technique

Optional surgical approachSurgical exposure can be improved by an extended trochanteric osteotomy. The greater trochanter, in continuity with a strip of the lateral proximal femoral cortex, is osteotomized to permit intramedullary access to remove the femoral component. The revision stem should bypass the distal extent of the osteotomy by two to three canal diameters. Place a cerclage cable slightly distal to the osteotomy before reaming, broaching, and inserting the stem to minimize the risk of propagating a crack or fracture. Once the final components are implanted, the osteotomy is reduced. In order to reduce the osteotomized bone fragment in its anatomic position, it may be necessary to shape the endosteal surface of the bone fragment with a curette or burr to fit against the lateral portion of the femoral component. To gain adequate proximal support and reduce the risk of implant failure, the use of adjunctive devices such as cables, cerclage wires, struts, etc. is recommended. Because of the intramedullary exposure gained by extended trochanteric osteotomy, over-reaming is less likely to be necessary to insert a bowed femoral stem than if the surgery is performed without an extended trochanteric osteotomy.

10

Femoral neck osteotomy

An osteotomy guide is available for proximal bone resection. The angled slot is for a standard collar stem, and the proximal horizontal slot is for a +15mm calcar stem. The osteotomy guide has a vertical scale in 5mm increments to help gauge neck height.

Resect the proximal bone by cutting through the osteotomy slot that corresponds to the implant collar type. When a calcar-type stem is selected, ensure that sufficient bone has been removed to allow the collar to fully seat.

Femoral preperation

The starter reamer is specifically designed with a bullet tip to open the proximal aspect of the femur to remove bone from the greater trochanteric region. The presence of this bone will be largely dependent on the stem previously implanted and the stem removal process. Use the starter reamer to remove lateral bone as shown. Removing lateral bone is important for maintaining neutral stem placement in respect to the femoral axis.

Caution Take care when handling reamers and broaches as they are sharp and may damage surgical gloves and soft tissue.

11

Femoral reaming (straight stems)

Rigid femoral reamers in 0.5mm increments are available for the porous straight stems.

The stem size is measured at the maximum diameter of the distal porous coating. The maximum diameter of the flutes is equal to the diameter of the porous coating.

Start reaming with a reamer 4 to 6mm smaller than the templated size or a reamer that has little or no resistance in the femoral canal.

For a line-to-line fit, ream the canal in 0.5mm increments until the last reamer matches the selected implant size. The canal can also be reamed 0.5mm smaller than the size for a tighter distal fit. The final reamer size should be based on bone quality, anatomy, and surgeon preference.

The stem length is measured from the standard collar area to the distal tip of the implant. Reaming depth is measured from the selected collar level to the distal tip of the implant. Use the straight implant reaming chart to determine the reaming depth for the porous straight implants. Seat the reamer to the appropriate depth mark on each reamer.

Femoral reaming (bowed stems)

Thin shaft reamers are available for the porous bowed stems. Ream the canal in 0.5mm increments until the reamer size is 0.5mm larger than the selected implant. The canal can be reamed larger if required to seat the implant. The final reamer size should be based on bone quality, anatomy, and surgeon preference.

The stem length is measured from the standard collar area to the distal tip of the implant. Reaming depth is measured from the selected collar level to the distal tip of the implant. Use the bowed implant reaming chart to determine the reaming depth for the bowed porous implants.

Surgeon tip I often ream the bowed stems line-to-line. If the fit is too tight as determined during implant insertion, the stem is removed and the canal reamed 0.5mm larger. — Douglas Becker, MD

Femoral broaching

Begin broaching two sizes smaller than the size of the last femoral reamer. The final broach should match the size of the selected implant, except for implant sizes 21 and 22. When using these larger implants the final broach should be a size 20. The femoral broaches are 0.5mm smaller than the porous coating level of the implant.

Standard collar implant broaching

For a standard collar implant, the proximal medial aspect of the broach should be flush with the osteotomy level.

Calcar implant broaching

The femoral broach has two black lines on the proximal medial section. The proximal line indicates the level of the +15mm calcar. When implanting a calcar-style implant, seat the broach so that the appropriate black line meets the medial resection level.

Surgeon tip If I have used an extended trochanteric osteotomy for removal of cement

and/or the femoral components to be revised, I like to close the osteotomy prior to canal preparation. I do this with bone clamps during preparation of the canal and then trial with the bone clamps in place. If I am satisfied with what I learned from the trial, I then apply my definitive cable fixation to the osteotomy prior to inserting the final stem. I find this greatly enhances the fixation that I obtain proximally as opposed to the more usual technique which is to insert the stem and then re-attach the osteotomized trochanter with cables. — James Waddell, MD, FRCS(C)

Standard collar trialing

Calcar trialing

Trialing (continued)

Trialing with the trial stem

When trialing with the trial stem, select the trial size that corresponds to the last broach used. The trial stem is 1.25mm smaller than the implant (diameter only) to prevent the trial from locking in the canal.

A modular collar is available to convert the standard collar trial to a +15mm. Insert the trial collar into the proximal hole for a +15mm calcar implant. Place the desired trial femoral head on the trial stem and reduce the hip to assess stability and range of motion.

Surgeon tip To get a better feel for the distal fit of the stem, I like to use the next larger trial size from the last reamer diameter. On a straight stem, for example, if the last reamer is a 14.5mm, it’s probably useful to insert the 16mm trial. This gives me a good idea how tight the actual implant will be. — Cecil Rorabeck, MD, FRCS(C)

17

Implant insertion

Assemble the threaded stem inserter by inserting the stem inserter pommel through the stem inserter frame. Engage the tip of the stem inserter frame into the stem driver slot on the selected implant and turn the pommel to thread the inserter onto the implant. Fully tighten the pommel before impaction.

Straight Stem Insertion

Insert the implant into the canal with hand pressure and verify proper implant version. Once the implant flutes have engaged the bone, the implant version cannot be changed without removing the implant. Use firm mallet blows to seat the implant. The implant can be removed by striking the underside of the threaded stem driver with a mallet.

Surgeon tip When using a cylindrical stem design, I believe it is important to know the exact dimensions of the reamers and implants used. Therefore, especially with bowed stems, I will use a ring gauge to measure the reamer and implant to 0.5mm. Based on these measurements, I can decide whether to ream line-to-line or otherwise. — Robert Barrack, MD

Surgeon tip In cases of considerable bone ectasia proximally, I find it helpful to use prophylactic cables or wires about the proximal femur. The bone is very fragile and propagation cracks can occur easily. — James Waddell, MD, FRCS(C)

Caution Do not use the Stem Inserter Pommel as a standalone instrument, either for stem insertion or removal.

Caution To gain adequate proximal support and reduce the risk of implant failure, the use of adjunctive devices such as cables, cerclage wires, struts, etc. is recommended.

18

Bowed Stem insertion

Assemble the bowed stem to the stem inserter with the same technique as the straight stem. Implant version must be correct before the implant encounters resistance in the canal. If the bowed stem stops progressing during insertion, remove the implant and enlarge the canal with a larger size thin shaft reamer.

Note A fully seated bowed stem will be extremely difficult to remove from the femur and may require an osteotomy to remove.

Surgeon tip If the implant does not advance visibly with forceful blows, the distance from the collar to the calcar should be measured in millimeters and re-measured after a series of blows to insure that it’s advancing steadily. If there’s no advancement with several hard blows, the pitch has changed, and the stem is still proud, the stem should be extracted and the canal over-reamed. — Robert Barrack, MD

Surgeon tip For a bowed stem, I find it occasionally necessary to introduce the stem initially for the first few centimeters with the bow turned 90º to its ultimate orientation and, once the tip of the stem has passed the initial proximal bow (anteversion), rotate the stem back to its desired position and gradually impact the stem. — James Waddell, MD, FRCS(C)

19

Implant trialing

Once the implant is fully seated, perform a final trial reduction to determine appropriate neck length. Fully engage the desired trial femoral head on the implant and reduce the hip to assess stability and range of motion.

Femoral reaming (225mm and 300mm stems)

Use thin shaft reamers for the 225mm and 300mm cemented stems. Ream the canal in 0.5mm increments until the reamer size matches the selected implant. This reaming method will provide a minimum 1.5mm cement mantle on each side of the implant.

It is unusual that axial reaming is necessary in this revision surgery. Preservation of cancellous bone is critical for allowing intrusion of cement into the cancellous bed thus enhancing fixation.

Prior to broaching it is necessary to remove the neocortex that has formed around the previous implant. Failure to do this prevents the cement-bone bond.

Trialing can be performed using either the broach or trial stem.

Trialing with the broach

Seat the final broach to the appropriate level for the selected implant (fully seated for standard collar, proximal black line for +15mm calcar). Remove the broach handle and place the matching trial neck onto the broach post. Place the desired trial femoral head on the trial neck and reduce the hip to assess stability and range of motion.

Note The broach length is shorter than the implant.

Trialing with the trial stem

When trialing with the trial stem, select the trial size that corresponds to the last broach used. The trial stem is the same size as the implant (for cemented). If increased stability is needed when trialing, use the femoral broach as a trial. A modular collar is available to convert the standard collar trial to a +15mm. Insert the trial collar into the proximal hole for a +15mm calcar implant. Place the desired trial femoral head on the trial stem and reduce the hip to assess stability and range of motion.

Preparing the femoral canal

Use a curette to remove any grossly loose cancellous bone. Irrigate the canal with saline solution and pulsatile lavage to remove all debris. Continue preparing the femur with the femoral canal brush to remove any remaining weak cancellous bone, blood clots, and marrow fats. Repeat lavaging as necessary to remove all remaining debris.

Surgeon tip While awaiting the appropriate cement texture, I find it helpful to remind the anesthesiologist to keep the patient’s blood pressure stable and relatively low. Epinepherine-soaked rags are placed in the canal at this time as well, preventing additional bleeding. — Kevin Garvin, MD

30

Placing the BUCK™ Cement Restrictor

The proximal flange of the cement restrictor should always be larger than the distal canal diameter. Screw the cement restrictor onto the inserter using a clockwise motion. Insert the device to the level of the medullary canal that has been predetermined. Once this level is reached, disengage the restrictor from the inserter using a counterclockwise twisting motion. Remove the inserter from the medullary canal. If it is necessary to remove the restrictor prior to cement insertion, it can be reattached to the inserter rod and pulled out of the canal. The surgeon may adjust the restrictor as many times as required.

Surgeon tip I find it helpful to place a small 10cc volume of cement distal to the plug if the canal is large and the plug does not remain stable. — Kevin Garvin, MD

Drying the femoral canal

Connect OR suction to the femoral suction absorber handle. Insert the femoral absorber into the femoral canal to dry the canal while mixing the cement.

31

Injecting cement

After removing the femoral canal suction absorber, immediately insert the nozzle of the cement gun deep into the femoral canal. Beginning at the distal end of the femoral canal, inject cement into the canal in retrograde fashion. Continue injecting cement until the canal is completely full and the distal tip of the nozzle is clear of the canal.

32

Pressurizing cement

Break off the long nozzle and place the femoral pressurizer over the short nozzle. Place the pressurizer against the proximal femur. This will occlude the canal and pressurize the cement. Maintain firm pressure for 30 – 60 seconds, depending on cement viscosity, to allow good cement interdigitation into trabecular bone. Withdraw the pressurizer from the canal and remove any extruded cement around the periphery of the pressurizer.

33

Implant insertion

Engage the tip of the stem inserter into the stem driver slot on the selected implant. Insert the implant into the canal with hand pressure while verifying proper implant alignment.

Implant trialingOnce the implant is fully seated and the cement has cured, perform a final trial reduction to determine appropriate neck length. Place the desired trial femoral head on the implant and reduce the hip to assess stability and range of motion.

34
