Tibial Shaft Fractures
Updated: May 6 2017

Tibial Shaft Fx Intramedullary Nailing

Preoperative Patient Care
Operative Techniques

Preoperative Plan


Template fracture reduction

  • draw key fragments of fracture and plan the forces required to obtain the reduction


Template instrumentation

  • measure diameter of the intramedullary canal and approximate length


Execute surgical walkthrough

  • describe key steps of the procedure to the attending verbally prior to the start of the case
  • describe potential complications and the steps to avoid them

Room Preparation


Surgical instrumentation

  • make sure tibia intramedullary nailing system is present before the start of the case


Room setup and equipment

  • radiolucent OR table
  • optional
  • large sharp periarticular clamps or Weber-style clamps
  • large external fixation system or femoral distractor
  • c-arm fluoroscopy
  • c-arm from contralateral side, perpendicular to bed


Patient positioning

  • patient supine with feet at the end of the bed, small bump under ipsilateral thigh
  • need to move all lights away from area directly over OR table as this will get in the way of guidewires and reamers
  • step stool to get better angle for reaming
  • prep and drape with full access to foot and ankle to judge intraoperative length, rotation, and alignment

Parapatellar Knee Approach


Plan out anterior approach to knee

  • options include
  • medial parapatellar (most common, described below)
  • lateral parapatellar
  • patellar tendon splitting
  • suprapatellar approach
  • in cases of decreased knee flexion, can also use suprapatellar approach through superolateral aspect of patella
  • incision and approach are made ~4cm proximal to the superior edge of the patella


Position leg on triangle and make incision

  • flex knee over radiolucent triangle
  • mark out inferior pole of patella, borders of patellar tendon, joint line, tibial tubercle
  • make incision from inferior pole of patella distally 2.5cm towards tibial tubercle along medial 1/3 of patellar tendon


Spread down to dissect paratenon

  • identify medial edge of patellar tendon and incise
  • retract patellar tendon laterally
  • insert self-retaining retractor
  • use a Gelpi to maintain access

Starting Point and Guidewire Insertion


Identify guidewire starting point

  • just medial to the lateral tibial spine on the AP radiograph
  • on anterior cortical downslope on lateral view


Open canal with starting point reamer

  • use cannulated starting point reamer to open canal (drill to metaphyseal bone)


Insert guidepin

  • guidepin should be placed parallel with canal on AP view and just posterior to parallel on lateral view


Advance guidewire proximal to fracture site

  • place balltip guidewire in canal with T-handle
  • place gentle bend at tip of wire

Fracture Reduction and Reaming


Fracture reduction

  • traction technique
  • reduce fracture by pulling traction over triangle
  • can use small blue towel bump behind leg as a bump
  • use mallet to hold pressure over fracture site
  • can use intramedullary finger reduction tool and/or pointed reduction clamps through skin incisions
  • traveling box technique
  • If working alone or with untrained assistant, or if reduction assistance is needed, apply traveling “box” traction before knee incision
  • can use femoral distractor over pins as an alternate to external fixator bars
  • insert pins through posterior distal tibia (or calcaneous) and posterior proximal tibia (just anterior to fibular head but in posterior proximal tibia)


Advance guidewire

  • once fracture reduced, manually push guidewire past fracture site to distal physeal scar


Check biplanar imaging to ensure wire is in canal


Measure nail length with ruler

  • make sure guidewire is seated at physeal scar


Start with size 9mm reamer, then ream up 0.5-1.0mm with each reamer

  • push down through starting hole into bone before starting reamer
  • this prevents eccentric reaming of your starting point
  • can use step stool to get better body position for reaming if needed
  • check chatter from reamer feedback and diaphyseal fit on C-arm imaging
  • minimal to no reaming at fracture site to minimize eccentric reaming
  • ream 1.0mm above size of final nail (i.e. size 12mm reamer head for size 11mm nail)
  • If a distal fracture, don't ream the distal tibia unless the guidewire is in perfect position

Nail Insertion with Alignment Techniques (blocking screws)


Obtain proper alignment

  • blocking screw technique
  • when coronal or sagittal malalignment is noted, blocking screws are placed on the concavity of the deformity
  • place posterior or lateral to the guide wire in the proximal segment in proximal 1/3 fractures
  • these screws serve as a pseudo-cortex to guide the nail and increase stiffness of the construct


Assemble nail

  • build nail on backtable and make sure targeting guide lines up with holes in nail


Manually advance nail

  • insert nail over guidewire and push into place manually as much as possible
  • advance to fracture site and minimize mallet use at fracture site to minimize iatrogenic comminution
  • insert nail fully and check lateral C-arm view at the knee to ensure the nail is sunk at or below the edge of the bone


Check alignment and rotation

  • check that rotation of the nail is aligned with 2nd metatarsal
  • if compression is needed across fracture site, insert distal interlocking screws via perfect circles technique then backslap distal fragment into proximal fragment
  • must sink nail into proximal segment enough to allow backslapping


Remove guidewire


Proximal Interlocking Screws


Place trochar onto bone

  • attach proximal targeting guide and mark skin with triple sleeves for 2-3 static holes
  • use a 15 blade through skin, spread down to bone with hemostat, place trochar of sleeve on bone


Place interlocking screw

  • remove inner sleeve then drill through 1st cortex
  • when hitting 2nd cortex, stop and measure, call out length, then finish 2nd cortex (2nd cortex adds 2-5mm)
  • remove inner sleeve and insert screw
  • be careful not to over tighten screws as they can sink into bone easily in metaphyseal bone


Repeat process above for placement of other interlocking screws if indicated

  • can lock screws proximally into nail if the instrumentation allows


Remove targeting guide and jig from nail


Distal Interlocking Screws


Obtain perfect circles

  • bring the knee into full extension and lay entire leg on sterile bumps
  • move to distal tibia and get perfect circles of interlock screws
  • ensure no rotation of the distal tibia is done while getting the fluoroscopic views (move the C-arm, not the leg)
  • magnification of fluoro (x2) can be used if desired, but is not necessary


Drill holes for interlocking screws

  • use a 15 blade scalpel to locate the nailhole on medial distal tibia, and incise through skin
  • spread down to bone with hemostat
  • place drill in hole, then center drill parallel to xray beam
  • drill toward center of C-arm beam
  • do not stop drill when bit at nail unless progress halted by eccentric drilling
  • if drilling is off, take drill off bit and leave bit in drilled hole
  • recenter the bit on fluoroscopy and use a mallet to drive it across the nail holes
  • this force may cause malalignment in distal fractures


Place interlocking screws

  • measure the depth with a depth gauge or with calibrated drill bit
  • remove drill quickly and insert screw
  • repeat above process for 2nd distal interlocking screw
  • have more freedom to move the limb for fluoroscopy after first screw placed


Obtain biplanar fluroscopic images of the proximal, middle, and distal tibia


Check limb length, rotation, alignment, and perform a knee ligamentous examination


Wound Closure


Irrigation, hemostasis, and drain

  • strongly flush out reamings from knee with saline bulb irrigation
  • irrigate until backflow is clear
  • cauterize peripheral bleeding vessels


Tissue Closure

  • patellar tendon splitting
  • close patellar tendon and paratenon layers with 0-Vicryl
  • subcutaneous layered closure with 3-0 Vicryl
  • skin closure with staples or suture
  • medial parapatellar
  • close parapatellar arthrotomy, subcutaneous and skin closure



  • soft incision dressings over knee and distal tibia
  • ACE wrap from distal thigh to toes to help with edema
