    Introdction

    Over the past several decades ante-grade humeral nailinghas becomethe treatment o choice or mosthumeral shat ractures. Retrogradehumeral nailinghas expanded the

    use o intramedullary nails.

    Studies have shown the ollow-ing benets to be associated withHumeral Nailing :Brie operative time (1)Minimal morbidity (1)Early return to unction o theextremity (2)In 90% o the cases, no external sup-port is needed (1, 2)Closed technique (4)

    Low inection rate (2, 5, 6)Very good pain relie in stabilization opathological ractures (2, 4)

    Compared to Plate and ScrewOsteosynthesis :Minimal damage to muscle, connec-tive tissue and vasculature (1, 3, 7)Reduced periosteal stripping and con-

    comitant sot tissue damage(1)Fewer radial nerve palsies (3, 4)Designed or load sharing instead oload bearing (2)Cosmetically smaller incision

    The T2 Humeral Nailing System isone o the rst humeral nailingsystems to oer an option or either anantegrade or a retrograde approach torepair ractures o the humerus.

    One Implant, Two Approaches

    Stryker Osteosynthesis has created alocking nail system, bring-ing togetherall the capabilities and benets o sep-arate antegrade and retrograde nailingsystems to create a single, integratedsurgical resource or xation o long-

    bone ractures.Furthermore, the development othe T2 Humeral Nailing System oersthe competitive advantages o :

    Dual nailing approach : Antegradeand Retrograde

    Accommodating reamed or

    unreamed procedures Static, controlled dynamic and

    apposition/compression lockingoptions

    Advanced Locking Mode forincreased rotational stability.

    Through the development o a com-mon, streamlined and intuitive surgi-

    cal approach, both in principle and indetail, the T2 Humeral Nailing Systemoers signicantly increased speedand unctionality or the treatmento ractures as well as simpliying thetraining requirements or all personnelinvolved.

    The T2 Humeral Nailing System is therealization o superior biomechanicalintramedullary stabilization.

    The system oers the option odierent locking modes : Static, transverse /oblique Dynamic Apposition/compression

    Advanced locking

    In some indications, a controlledapposition/compression o bone rag-ments can be applied by introducinga compression screw rom the top onail. To urther increase rotationalstability, the nail can be locked aterutilizing the apposition/compressioneature.

    The benecial eect o apposition/

    compression in treating long-boneractures in cases involving transverseand short oblique ractures that areaxial ly stable is well documented(15, 16, 19).

    The compression screw is pushedagainst the proximal PartiallyThreaded Locking Screw (ShatScrew) that has been placed in theoblong hole, drawing either the distalor the proximal segment towards theracture site. In stable ractures, thishas the biomechanical advantage ocreating active circumerential com-

    pression to the racture site, transer-ring axial load to the bone, andreducing the unction o the nail as aload bearing device (17).

    This ability to transer load back tothe bone can reduce the incidence oimplant ailure secondary to atigue.Typical statical ly locked nails unc-tioning as load bearing devices havereported ailure rates in excess o 20%(18).

    Common 4mm cortical screws sim-pliy the surgical procedure. FullyThreaded Locking Screws are avail-able or regular locking procedures.Partially Threaded Locking Screws(Shat Screws) are designed or appli-cation o apposition/compression.

    One common Humeral Compression

    Screwto close the racture site, andEnd Caps in six sizes are available toprovide an improved t or every indi-cation to allow nail length adaptationater insertion and to prevent boneingrowth.

    All implants o the T2 HumeralNailing System are cannulatedand made oType II anodizedtitanium alloy (Ti6AL4V) orenhanced biomechanical and bio-

    medical perormance.

    The T2 Humeral Nail is intendedto provide temporary stabilization

    o various types o ractures,malunions and nonunions o thehumerus.The nails are inserted usingan opened or closed techniqueand can be static, dynamic andcompression locked.The subject and predicate devicesare indicated or use in thehumerus.Types o ractures include, butnot limited to ractures o thehumeral shat, non-unions,malalignments, pathologicalhumeral ractures, and impendingpathological ractures.

    Indications Precautions

    The physicians education, trainingand proessional judgement mustbe relied upon to choose the mostappropriate device and treatment.Conditions presenting an increasedrisk o ailure include:

    Any active or suspected latentinection or marked localinfammation in or about theaected area.Compromised vascularity that

    would inhibit adequate bloodsupply to the racture or theoperative site.Bone stock compromised bydisease, inection or priorimplantation that can not provideadequate support and/or xationo the devices.Material sensitivity, documentedor suspected.Obesity. An overweight or obesepatient can produce loads on theimplant that can lead to ailure

    o the xation o the device or toailure o the device itsel.Patients having inadequate tissuecoverage over the operative site.

    Relative Contraindications

    Indications, Precations and Contraindications

    Implant util ization that wouldinterere with anatomicalstructures or physiologicalperormance.Any mental or neuromuscular

    disorder which would createan unacceptable risk o xationailure or complications inpostoperative care.Other medical or surgicalconditions which would precludethe potential benet o surgery.

    An X-Ray Template (1806-0003) isavailable or pre-operative planning.

    Thorough evaluation o pre-operativeradiographs o the aected extremityis critical. Careul radiographic exami-nation can help prevent intra-operativecomplications.

    I X-Rays show a very narrowintramedullary canal in the distal parto the humerus, retrograde humeralnailing is not possible.

    The proper nail length when inserted

    antegrade should extend rom sub-chondral bone proximally, to 1cmabove the olecranon ossa distally.

    The retrograde nail length is deter-mined by measuring the distance rom1cm above the olecranon ossa to thecenter o the humeral head.

    In either approach, the surgeon shouldconsider the apposition/compressioneature o the T2 Humeral Nail,

    knowing that 6mm o active apposi-tion/compression is possible, prior todetermining the nal length o theimplant.

    Note:Check with local representativeregarding availability o nail sizes.

    The patient is placed in a semireclinedbeach chair position or supine ona radiolucent table. Patient position-ing should be checked to ensurethat imaging and access to the entrysite are possible without excessivemanipulation o the aected extremity(Fig. 1). The image intensier is placedat the legside o the patient ; the sur-geon is positioned at the headside.

    IncisionA small incision is made in line withthe bers o the deltoid muscle ante-rolateral to the acromion. The deltoid

    is split to expose the subdeltoid bursa.Palpate to identiy the anterior andposterior margins o the greatertuberosity and supraspinatus tendon.The supraspinatus tendon is thenincised in line with its bers(Fig. 2).

    The real rotation o the proximal rag-ment is checked (inversion or rever-sion), considering that the entry pointis at the tip o the greater tubercle. Ithe proximal ragment is inverted,the entry point is more anterior. I theproximal ragment is in external rota-tion, the entry point is more lateral. Itis recommended to localize the entrypoint under image intensier control,also palpating the bicipital groove,the portal is about 10mm posterior tothe biceps tendon. This will make theentry portal concentric to the medul-lary canal.

    The entry point is made with theCurved, cannulated Awl (1806-0040)(Fig. 3). The 2.5 800mm Ball TipGuide Wire (1806-0083S) is thenintroduced through the awl underimage intensication into the meta-physis, central to the long axis o thehumerus.

    Alternatively, the optional Crown Drill(1806-2020) may be used over theK-Wire with Washer (1806-0051S) orentry point preparation. The K-Wirewill help to guide the Crown Drillcentrally (Fig. 3a).

    Then, the 3 285mm K-Wire (1806-0050S) is introduced under imageintensication into the meta-physis,central to the long axis o the humer-us.

    The cannulated 10mm Rigid Reamer(1806-2010) may be used over theK-Wire and the proximal metaphysisshould be drilled to a depth o at least6cm.

    Note:During opening the entry portal

    with the Awl, dense cortex mayblock the tip o the Awl. An AwlPlug (1806-0032) can be insertedthrough the Awl to avoid penetra-tion o bone debris into the can-nulation o the Awl shat.

    For reamed techniques, the2.5 800mm Ball Tip Guide Wire(1806-0083S) is inserted across theracture site.The Reduction Rod (1806-0363) maybe used as a racture reduction tool toacilitate Guide Wire insertion acrossthe racture site (Fig. 5).

    Reaming is commenced in 0.5mmincrements until cortical contact isappreciated. Final reaming should

    be 1mm1.5mm larger than the dia-meter o the nail to be used.

    The Guide Wire Pusher can be used tohelp keep the Guide Wire in positionduring reamer shat extraction. Themetal cavity at the end o the handlepushed on the end o the power toolacilitates to hold the Guide Wire inplace when starting to pull the powertool. When close to the Guide Wireend place the Guide Wire Pusher with

    its unnel tip to the end o the powertool cannulation. While removing thepower tool the Guide Wire Pusher willkeep the Guide Wire in place(Fig. 6 & 7).

    Note:Prior to nail insertion pleasecheck correct alignment byinserting a drill bit through theassembled Tissue Protection andDrill Sleeve placed in the required

    holes o the targeting device.

    Upon completion o reaming andGuide Wire exchange, the appropriatesize nail is ready or insertion.Advance the nail through the entrypoint past the racture site to theappropriate level.

    Gentle rotation o the nail may benecessary to start the nail insertion.The nail should be advanced withmanual pressure. Aggressive use o

    the slotted hammer can result inadditional ractures. I the nail doesnot advance easily, a check with imageintensication should be made to seei the nail angle is too steep resultingin the nail impinging on the medialcortex.

    The Slotted Hammer (1806-0170)can be used to insert the nail over theGuide Wire.DO NOT hit the Target Device.

    Note:A chamer is located on theworking end o the nail todenote the end under X-Ray.Three circumerential groovesare located on the insertionpost at 2mm, 6mm, and 10mmrom the driving end o the nail(Fig. 14-16). Depth of insertionmay be visualized with the aid ofuoroscopy.

    In unstable or comminuted ractures,the nail should be used as a standardinterlocking nail. Static locking o thedistal holes will help maintain thelength o the bone and the rotationalstability o the racture.

    The Short Tissue Protection Sleeve,together with the Short Dril l Sleeveand the Short Trocar, are positionedthrough the static locking hole on theTarget Device. A small skin incision

    is made, and the assembly is pushedthrough until it is in contact with thelateral cortex o the humerus (Fig. 20).

    Note:Especially in the proximalhumerus, use image inten-sication to help ensure the TissueProtection Sleeve is fush with thecortex or you could lose 12mm oscrew measurement accuracy.

    The Trocar is removed while theTissue Protection Sleeve and the Dril lSleeve remain in position.

    For accurate drilling and easy determi-nation o screw length, use the center-tipped, 3.5 230mm calibrated Drill(1806-3540S). The centered Drill isorwarded through the Drill Sleeveand pushed onto the cortex.Ater the rst cortex is drilled to theappropriate level the screw length maybe read directly o o the Drill at the

    end o the Drill Sleeve (Fig. 21).

    Caution:Make sure the Tissue ProtectionSleeve/Drill Sleeve Assembly is

    seated on bone prior to selectingnal screw length.

    Apposition/Compression Locking ModeIn transverse or axially stable racturepatterns, active apposition/compres-sion increases racture stability andenhances racture healing. The ante-grade T2 Humeral Nail provides theoption to treat a humerus racturewith active mechanical apposition/compression prior to leaving theoperating room.

    Note:Distal freehand static lockingmust be perormed prior toapplying active, controlled apposi-tion/compression to the racture

    site.

    I active apposition/compression isrequired, a Partially Threaded LockingScrew (Shat Screw) is inserted via theTarget Device in the dynamic positiono the oblong hole. This will allow ora maximum o 6mm o active, con-trolled apposition/compression. Inorder to insert the Partially ThreadedLocking Screw (Shat Screw), drillboth cortices with the 3.5 230mm

    Drill (1806-3540S). Next, the nearcortex ONLY is overdrilled with the4.0 180mm Drill (1806-4000S).

    Note:Ater the opposite cortex is drilledwith the 3.5 230mm drill, thecorrect screw length can be readdirectly off of the calibrated Drillat the end of the Drill Sleeve.

    Ater the Partially Threaded LockingScrew (Shat Screw) is inserted, the

    Nail Holding Screw is removed,leaving the insertion post intact withthe nail (Fig. 35). This will act as aguide or the Compression Screw. TheCompression Screw with the Compres-sion Screwdriver Shat (1806-0263)assembled on the Teardrop Handle isinserted through the insertion post(Fig. 36).

    Patient PositioningThe patient is placed on a radiolu-cent table in the prone position orlateral decubitus position. The aectedarm is supported on an arm board orhand table. The shoulder is in 90abduction, the elbow joint fexed alsoin a 90 position. In this position, rac-tures can be reduced in correct rota-tion.

    Patient positioning should be checkedto ensure that imaging o the entry siteat the proximal humerus is possible.This allows the elbow to be hyperfexed to accommodate insertion o the

    implant parallel to the humerus.

    IncisionA posterior approach is used toaccess the distal humerus. Starting at

    the tip o the olecranon, a 6cm incisionis made in a proximal direction. Thetriceps tendon is split and muscle tis-sue is bluntly dissected and retracteduntil the upper edge o the olecranonossa is displayed.

    The distal insertion point or thenail is one centimeter above the ole-cranon ossa. The Insertion SiteTemplate (703117) may be used to helpdetermine the appropriate insertion

    site (Fig. 45). The medullary canal isopened using the Drill 3.5 130mm(1806-3550S) by drilling a set olinear holes (Fig. 46). The holes arethen joined with the Sel-guiding RigidReamer (703125) (Fig. 47).

    The cortical bone is removed distallyto the level o the olecranon ossa withthe rigid reamers or small rongeur.

    Caution :Although the tip o the nail has a 4degree bend that acilitates distalnail insertion, high compressiveorces during nail insertion can

    result in ractures o the distalhumerus i the insertion openingis too short or too steep.

    Unreamed TechniqueThe T2 Humeral Nail is cannulated,and may be introduced in an un-reamed ashion over a Smooth TipGuide Wire. This simplies racturereduction and reduces the risk o iatro-genic distal ractures caused by tryingto reduce the racture with the nail.

    Freehand Proximal LockingThe reehand technique is used toinsert Locking Screws into both theA/P and M/L holes in the nail.Rotational alignment must be checkedprior to locking the nail statically.

    Multiple locking techniques andradiolucent drill devices are availableor reehand locking. The critical stepwith any reehand locking technique,proximal or distal, is to visualize aperectly round locking hole with theC-Arm.

    The center-tipped 3.5 230mm

    Drill (1806-3540S), or the optional3.5 130mm Dril l (1806-3550S), isheld at an oblique angle to the centero the locking hole (Fig. 73). UponX-Ray verication, the Drill is placedperpendicular to the nail and drilledthrough the anterior cortex. Conrmthese views in both the A/P and M/Lplanes by X-Ray.

    Ater drilling both cortices, the screwlength may be read directly o o the

    Screw Scale, Short (1806-0360) at theorange color coded ring on the center-tipped Drill (Fig. 74). As with distallocking (Fig. 67, p. 27), the position othe end o the drill is equal to the endo the screw as they relate to the arcortex.

    Routine Locking Screw insertion isemployed with the assembled ShortScrewdriver Shat and the TeardropHandle.

    I possible, the proximal humerusshould be locked with two FullyThreaded Locking Screws (Fig. 75).

    Note :Use image intensication to con-rm screw position within thenail as well as screw length.

    Alternatively, the Screw Gauge can beused to measure the screw length.

    End Cap InsertionAter removal o the Target Device, anEnd Cap is used to reduce the poten-tial or bony ingrowth into the proxi-mal threads o the nail.

    End Caps are available in six sizes(Fig. 76).

    The End Cap is inserted with the ShortScrewdriver Shat assembled on theTeardrop Handle ater intra-operativeradiographs show satisactory reduc-tion and hardware implantation(Fig. 77). Fully seat the End Cap tominimize the potential or loosening.

    Caution:To avoid impingement, careullyselect the length o t he End Cap.

    Close the wound using standard tech-nique.

    Dynamic Locking ModeControlled dynamic locking may beutilized or transverse or axially stableractures.

    Retrograde dynamization is perormedby statically locking the nail proxi-mally.

    The guided Locking Screw is thenplaced in the dynamic position o theoblong hole. This allows the nail tomove, and the racture to set tle while

    torsional stability is maintained(Fig. 78).

    In transverse or axially stable racturepatterns, active apposition/compres-sion increases racture stability andenhances racture healing. Theretrograde T2 Humeral Nail providesthe option to treat a humerus racturewith active mechanical apposition/compression prior to leaving theoperating room.

    Note :Proximal reehand static lockingmust be perormed prior to apply-ing active, controlled apposition/compression to the racture site.

    I active apposition/compression isrequired, a Partially Threaded LockingScrew (Shat Screw) is inserted via theTarget Device in the dynamic positiono the oblong hole. This will allow ora maximum o 6mm o active, con-trolled apposition/compression. Inorder to insert the Partially ThreadedLocking Screw (Shat Screw), drillboth cortices with the 3.5 230mmDrill (1806-3540S). Next, the near

    cortex ONLY is overdrilled with the4.0 180mm Drill (1806-4000S).

    Note :Ater the opposite cortex is drilled

    with the 3.5 230mm Drill, thecorrect screw length can be readdirectly off of the calibrated Drillat the end of the Drill Sleeve.It may be easier to insert theCompression Screw prior to ullyseating the nail. Once the nailtip has cleared the racture site,

    the Guide Wire (i used) is with-drawn. With the proximal portiono the nail not ully seated andextending out o the bone, theAdvanced Compression Screw isinserted.Care should be taken that theshat o the Compression Screwdoes not extend into the area othe oblong hole.

    In order to achieve additional xationand to reduce the load on the PartiallyThreaded Locking Screw (ShatScrew), the design o the T2 HumeralNail provides the opportunity to insertan additional Fully Threaded LockingScrew in the other transverse hole atthe driving end o the nail aterapposition/compression is utilized.

    Prior to guided locking via the TargetDevice, the Nail Holding Screw mustbe tightened using the InsertionWrench.

    The Compression Screw is insertedwith the Compression ScrewdriverShat. Fix the Compression Screw onthe Compression Screwdriver Shat.Remove the Nail Holding Screwleaving the Target Device in place(Fig. 82). Advance the CompressionScrew through the Target Device untilthe desired amount o compression isachieved. Visualize depth o insertionwith the aid o fouroscopy (Fig. 83).

    Note:As previously described, it may beeasier to insert the CompressionScrew prior to ully seating thenail.

    To reattach the Target Device to thenail, detach the Compression ScrewDriver and screw the Nail HoldingScrew into its required position. Toreattach the Target Device to the nail,detach the Teardrop Handle rom theCompression Screwdriver Shat and

    screw the Nail Holding Screw over theCompression Screwdriver Shat intoits required position.

    To insert the second transverse FullyThreaded Locking Screw, ollow thelocking procedure or static locking(Fig. 84 and 85).
