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.

The T2 System has not been evaluatedor saety and compatibility in the MR

environment.The T2 System has not been testedor heating or migration in the MRenvironment.

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.

The selected nail is assembled ontothe Target Device (1806-0143) withthe Nail Holding Screw (1806-0163).Tighten the Nail Holding Screwsecurely with the Insertion Wrench(1806-0135) so that it does not loosenduring nail insertion (Fig. 13).

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.

Static Transverse

Locin Mode

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.

Warning:Do not drill through the far cor-tex as this will penetrate the joint.

Note:The position o the end o theDrill as it relates to the far cortexis equal to where the end o thescrew will be. Thereore, i the endof the Drill is 3mm beyond the farcortex, the end o the screw willalso be 3mm beyond.The Screw Gauge, Short, is cali-brated so that with the bend at theend pulled back fush with the ar

cortex, the screw tip will end 3mmbeyond the ar cortex (Fig. 21).

When the Drill Sleeve is removed,thecorrect 4.0mm Locking Screw isinserted through the Tissue ProtectionSleeve using the Screwdriver Shat,Short (1806-0222) with the TeardropHandle (702429, Fig. 22). The screw isnear its proper seating position whenthe groove around the shat o thescrewdriver is approaching the end o

the Tissue Protection Sleeve.

Use image intensication to conrmscrew position through the nail as wellas screw length.

Repeat the locking procedure or theother statically positioned LockingScrew (Fig. 23).

Caution:The coupling o Elastosil handlescontains a mechanism with one

or multiple ball bearings. In caseo applied axial stress on theElastosil handle, those compo-nents are pressed into the sur-rounding cylinder resulting in acomplete blockage o the deviceand possible bending.To avoid intra-operative com-plications and secure long-termunctionality, we mandate thatElastosil handles be used only ortheir intended use.

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

Multiple locking techniques and radio-lucent drill devices are available orreehand locking. The critical stepwith any reehand locking technique,proximal or distal, is to visualize aperectly round locking hole with theC-Arm.

Caution:

In order to avoid damage tothe neurovascular structure, alimited open approach should beconsidered.

The center-tipped 3.5 230mmDrill (1806-3540S), or the optional3.5 130mm Dril l (1806-3550S), isheld at an oblique angle to the centero the locking hole (Fig. 28 and 29).Upon X-Ray verication, the Drill isplaced perpendicular to the nail and

Dynamic Locking ModeWhen the racture prole permits,controlled dynamic locking may beutilized or transverse or axially stableractures.

Antegrade dynamization is perormedby statically locking the nail distally.

The guided Partially ThreadedLocking Screw (Shat Screw) is thenplaced in the dynamic position othe oblong hole. This allows the nailto move, and the racture to settlewhile torsional stability is maintained(Fig. 34).

Ater 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. 32).

The End Cap is inserted with the ShortScrewdriver Shat assembled on theTeardrop Handle ater intra-operativeradiographs show satisactory re-duction and hardware implantation(Fig. 33). Fully seat the End Cap tominimize the potential or loosening.

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).

Note: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 takenthat the shat o the CompressionScrew does not extend into thearea o the oblong hole.

The Short Tissue Protection Sleeveis removed and the CompressionScrew is gently tightened utilizingthe two-nger technique (Fig. 37). Asthe Compression Screw is advancedagainst the 4.0mm Partial ly ThreadedLocking Screw (Shat Screw), it drawsthe distal racture segment towards theracture site, employing active appo-sition/compression (Fig. 38). Imageintensication will enable the surgeonto visualize active apposition/compres-

sion. Some bending o the transversePartially Threaded Locking Screw(Shat Screw) may be seen.

Note:Apposition/compression must becarried out under X-Ray control.Over-compression may cause thenail or the Partially ThreadedLocking Screw (Shat Screw) toail.When compressing the nail,the implant must be inserted a

sae distance rom the entry pointto accommodate or the 6mm oactive compression. The threegrooves on the insertion post aredesigned to help attain accurateinsertion depth o the implant.

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).

Note:The drill guide slots o theretrograde Insertion Site Template(703117), must be centered andparallel to the medullary canal(long axis o the humerus).

Entry PointFinal insertion site preparation is per-ormed with the Conical Rigid Reamer(703126) to create a longitu-dinal ovalcortical hole at least 3cm in length and1cm in width (Fig. 49).

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.

The 2.2 800mm Smooth Tip Guide

Wire (1806-0093S) is inserted underimage control through the distal rag-ment and into the desired positionwithin the proximal humerus usingthe Guide Wire Handle and Chuck(1806-1095 and 1806-1096) (Fig. 48and 50).

The Reduction Rod (1806-0363) maybe used as a racture reduction toolto acilitate Guide Wire insertion(Fig. 51). The Guide Wire is advanceduntil the tip rests at the center o the

humeral head. The Guide Wire shouldlie in the center o the metaphysis inboth the A/P and Lateral views to helpavoid oset positioning o the nail.The Guide Wire Handle is removedleaving the Guide Wire in place.

Reamed TechniqueFor reamed techniques, the2.5 800mm Ball Tip Guide Wire(1806-0083S) is inserted through theracture site. The Reduction Rod orthe Universal Rod, Short with theoptional Reduction Spoon may beused as a racture reduction tool toacilitate Guide Wire insertion acrossthe racture site (see Fig. 51).

Reaming is commenced in 0.5mmincrements until cortical contact isappreciated. (Fig. 50). The nal reamershould be 1mm1.5mm larger thanthe diameter 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 withits unnel tip to the end o the powertool cannulation. While removing the

power tool the Guide Wire Pusher willkeep the Guide Wire in place (Fig. 53and 54).

Note:The driving end o the 7mm nailis always 8mm.

When reaming is complete, the TefonTube (1806-0073S) should be used toexchange the Ball Tip Guide Wire withthe Smooth Tip Guide Wire or nailinsertion.

Note:Do not insert any T2 HumeralNail over any Ball Tip Guide Wire.

An unreamed technique can beconsidered in cases, where the medul-lary canal has the appropriate dia-meter. In these cases, the nail canbe introduced over the 2.2800mmSmooth Tip Guide Wire (1806-0093S).

Upon completion o reaming andGuide Wire exchange, the appropriatesize nail is ready or insertion and isadvanced through the entry point pastthe racture site to the appropriatelevel.

Gentle rotation o the nail may benecessary to start nail insertion. Thenail should be advanced with manualpressure (Fig. 58). Aggressive useo the slotted hammer can result inadditional ractures. I the nail doesnot advance easily, a check with imageintensication should be made to see ithe nail angle is too steep and the nailis impinging on the anterior cortex. Inthis case, it may be necessary to ur-ther widen the insertion opening.

Note:A chamer is located on the driv-ing end o the nail to denote theend under X-Ray. Three circum-erential grooves are located onthe insertion post at 2mm, 6mm,and 10mm rom the driving endof the nail (Fig. 59). Depth ofinsertion may be visualized withthe aid o fuoroscopy.

The 3 285mm K-Wire may be

inserted through the Target Devicewhich identies the junction o thenail and insertion post.

Insertion o the nail into the racturezone should be monitored underimage intensication.

Static Transverse Locin Mode

In unstable or comminuted ractures,the nail should be used as a standardinterlocking nail. Static locking willhelp maintain the length o the nailand the rotational stability o the rac-ture.

The Short Tissue Protection Sleevetogether with the Short Dril l Sleeveand the Short Trocar are positionedthrough the static locking hole on theTarget Device. A small skin incisionis made and the assembly is pushed

through, until it is in contact with theposterior cortex o the humerus.

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 the

Tissue Protection Sleeve and the Dril lSleeve remain in position.

For accurate drilling and easy de-termination o screw length, use thecenter-tipped 3.5 230mm calibratedDrill (1806-3540S). The Drill is or-warded through the Drill Sleeve andpushed onto the cortex.

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

seated on bone prior to selectingnal screw length.

Ater drilling both cortices, the screwlength may be read directly o o thecalibrated Drill at the end o the DrillSleeve (Fig. 66 and 67).

Note :The position o the end o theDrill as it relates to the far cortex

Complete range o modular andixed-head reamers to matchsurgeon preerence and optimizeO. R. eiciency, presented in ullysterilizable cases.

Studies1 have demonstrated thatthe pressures developed withinthe medullary cavity through the

introduction o unreamed IMnails canbe ar greater than those developedduring reaming but this dependsvery much upon the design o thereamer.

Ater a three year development study2involving several universities, theactors that determine the pressuresand temperatures developed duringreaming were clearly established.These actors were applied to the de-

velopment o advanced reamers thatdemonstrate signiicantly better per-ormance than the best o previousdesigns3.
