– anesthesic considerations :
– surgeons should insist on general anesethesia or short spinal anesthesia so that the surgeon can evaluate for postop compartment syndrome ;

– compartment syndrome without pain !
– dumb compartment syndrome complicating entire knee arthroplasty : continuous epidural anesthesia masked the pain .
– Patient Position and Fracture Reduction:
– before the font starts, the surgeon should have a plan to obtain frx reduction, noting the sum of assistant and equipement available ;
– status the OR lights off from the center of the table, so that the guidebook wires do not touch.
figure of four position :
– lapp as the arthrscopic position, with hep and knee bend over the opposite stage ;
– minimzes the angulatory displacement in the saggital plane ;
– note that once the proper entrance trap is established ( AP view ), the reduction on the lateral view is most important ;
– w/ proximal or distal fractures, consider need for blocking screws ;
– w/ exposed fractures ( or cases in which a fasciotomy has been performed ) a lineal reduction is performed through the wind ;
– direct decrease is much critical for proximal fractures ;
– if the reduction is unmanageable to achieve, then a cannulated nail system should be used ( both for ream and for nail down interpolation ) ;

entry into the IM canal
reaming of tibial fractures:
– over-reaming by 0.5 to 1 millimeter is probably indicated for all tibial IM breeze through procedures since it helps guarantee proper complete
diameter ( avoiding nail captivity and/or posterior cortex blow out ) ;
– compression bandage should never be inflated during ream of the intramedullary canal, since this risks thermal necrosis ( compression bandage is
rarely needed ) ;
– avoid eccentric reaming:
– remember that the reamer follows put of steer wire and that breeze through follows the path left by the reamer and therefore
template wire position needs to be carefully checked during reaming to make ensure that it is centrally located on two
radiographic views ;
– bizarre ream will cause the complete to enter into the duct eccentrically which will end up induce the distal fracture
shard to move into varus if the ream is eccentric laterally and will cause it to move into valgus if the
ream is excessively median ;
determine nail width:
– this is critical because under-sizing nail diameter will give a free match and over-sizing breeze through may cause nail captivity and
resultant back tooth cerebral cortex frx ;
– ream is the best way to determine collar width ;
– w/ unreamed proficiency, sounds can be used to determine the diameter of the canal and the proper complete size ;
– largest sound that passes well thru the isthmus is decline choice ;
– uncomminuted distal frx may require a smaller diameter nail or ream, as compared to comminuted isthmus frx, because of
long intervention meet within canal ;
– reference : fatigue failure in little diameter tibial nails.
determine nail length:
– this is best determined once the initial starting reamer is placed down the canal ;
– w/ the reamer down the canal, the fracture can normally be reduced no shortening or angulation ;
– consumption flouro to mark proximal submission position at degree of tibial tableland, & distal position at physeal scratch ;
radiolucent ruler:
– measures the proper breeze through distance ;
– remember that if the rule is placed on top of the tibia ( rather beside it ), then there will be a tendency to undersize length ;
pitfalls :
– do not measure nail duration from the proximal tibial joint line but rather measure duration from the breeze through entrance locate ;
– external oblique muscle fractures tend to be shortened at the fracture site and cross fractures or comminuted frx may be distracted ;
– therefore measurement of oblique fractures may cause nails to be shortstop and transverse/comminuted fractures may cause
nails to be excessively retentive ;
– with distal devious fractures often nail ends up being excessively short-circuit ;
– note that a collar that is excessively long may have the effect of distracting the fracture locate, when the tip of the nail engages the
physeal scar continued impaction may distract the fault site ;

– An easy and accurate preoperative method acting for determining tibial nail lengths
– tibial tubercle-medial malleolar distance in determining tibial nail down distance.

– Insertion of Nail:
– visualize considerations in proximal tibial fractures
– anterior to nail interpolation, test the proximal mesh device to ensure that the drill will pass w/o difficulty ;
– do not allow the nails to touch the hide as it is being inserted.
check the nail progression:
– as the collar is hammered down the canal, its progression needs to be followed on the lateral view ;
– if nail fails to advance with each coke of the forge, barricade, for the nail is impinging on the cortex or it besides big for the duct ;
– attempts to drive it further may fracture the cortex ;
– although the collar may occassionally excessively big, the common causal agent for impingement is improper alliance of the collar within canal ;
– fluorine racture reduction: ( completed a soon as the nail crosses the fracture site ) ;
– miss of cortical continuity ( fracture opening ) is the one major gene that surgeon can control with respect to frx healing ; ( non-union )
– capable fractures and cross fractures are other risk factors for fracture non union ;
– w/ proximal or distal fractures, consider need for blocking screws ;

rotational alignment:
– once the nail down crosses the fracture locate, great care must be taken to restore rotational alliance ;
– use flouro or the bi-malleolar axis to determine proper conjunction ;

– Findings related to rotational malalignment in tibial fractures treated with ream intramedullary smash
nail centralization:
– as the nail is driven thru the proximal fragment, it is crucial that it centralizes prior to reaching the fault locate ;
– if nail does not centralize prior to reaching fracture site, then remove nail, re-ream the canal, and consider adding a
buttocks bicortical obstruct screw ;
fracture compression:
– once the smash is across the fracture site, place antagonistic coerce across the foot to provide frx compression as the complete is
drive distally ;
– note that fracture compression is chiefly required with mid shaft fractures, where as in contrast, distal one-third fractures need
to be brought out to length and held with two proximal and two distal interlocking screws ;


– Interlocking:
– proximal inter-locking
– distal interlock : prior to distal interlock, ensure that there is optimum frx site compression ;
– two screws should be used if the status of the cheat is within 4 centimeter from the fracture site ;

 – Post Operative Care:
– if stability of the fracture is in wonder, then below stifle cast immobilization and touch down wt carriage are used until healing ;
– once partial fracture curative has taken place, consider a functional couple or consider a below knee cast with the back of the
foundation and ankle removed to allow ankle dorsiflexion ;
– active dorsiflexion and plantarflexion stresses the tibia and produces displacements exchangeable to wt bear ;

– static interlock : most tibial fractures heal in the inactive interlock mode ;
– dynamization :
– removal of proximal or distal screws allows axile load of tibia ;
– regard at 3 months in axially stable fractures with no callus ;

numbness in first web space, but no clinical affair of extensor muscle digitorum longus or tibialis front tooth ;
– there was good convalescence of muscle function within 3-4 months in all cases, but after one year 3 patients still had some
