Open tibia fractures have a high risk of infection.
It is well accepted that soft tissue injuries in open fractures should be debrided agressively, while bone should be preserved as much as possible. Is bone not a tissue or does it responds better to infection?
I am presenting a case of an open tibia fracture (high energy injury looking from the X-rays and CT scan) and the way we are managing it.
At the time of starting this blog we have completed or almost completed 20 patients with similar injuries. Results are encouraging and pending definitive review and publications.
25 August 2016
Initial X-rays after review in our A&E.
CT scan reconstructions - coronal
CT scan reconstructions - saggital

Images below show the tibia after damage control surgery, skeletal stabilisation and wound dressing (VAC).
01 September 2016
Definitve debridement of bone and soft tissue, cement spacer with antibiotic beads and soft tissue cover.
26 September 2016
After successful soft tissue cover and infection prevention temporary external fixator was replaced by TSF fine wire frame. At the same time corticotomy for bone transport was done and cement spacer removed with another set of reabsorbable antibiotic beads put in the defect. Post op X-rays are below.
One month after the injury we have definitive soft tissue cover, definitive skeletal stability and infection free. There are certainly quicker ways to do it, but are they better and more reliable/predictable?
07 October 2016
Still significant pain, otherwise stable frame. Everything as planned. Bone transport started - gap in the proximal tibia is increasing.
18 October 2016
Good progress but there is still pain. No obvious infection around the wound - free flap (soft tissue cover).
01 November 2016
One of the wires in the transported fragment became infected and was very painful. As we already have 4 wires and two half pins (which we preserved from the initial surgery) in the transported fragment we can/may safely remove the infected wire under sedation. In my opinion it is too painful to do it in clinic or even under "gas and air".
Otherwise, X-rays show nice regenerate and the position of the distal fragment is improving. Hopefully we will dock it soon but the free flap is restricting us from doing it any faster. We will certainly need some time to accommodate.
06 November 2016
Lengthening progressing well. Good quality regenerate. Stiffness of the knee is not improving. CPM was organised. Pin sites still inflamed but overall improved.
13 November 2016
Good progress. Pin site infection under control. Knee flexion contracture still present but it is improving.
Excellent quality of regenerate. Further progress in transport - 7mm in last 14 days. As planned. Still 30mm to go before fibula disimpacted. At that point will dock it and fine tune the leg length.
03 January 2017
No major problem. Pin sites OK.The knee is still a bit stiff but improving.
X-rays show good progress and excellent regenerate. Fibula is slowly geting back to length.
07 February 2017
Further progress. Some swelling around the transported fragment which could represent an infection. But it does go down during the night. Antibiotics for a week.
Leg length more or less restored.
Next task is to dock the fragment using the frame. A new prescription was given to complete the job. Hopefully in second attempt.
14 February 2017
Old haemathoma bursted. Pain improved.
Prescription completed. Position acceptable. Will compress the docking site further.
28 February 2017
Improved soft tissues. Docking completed and docking site well compressed (bent olive wires). No further treatment for the docking site planned at the moment.
28 March 2017
No major issues. Pain is still present. No obvious sign of infection. Walking still restricted but I believe it is improving.
As you can see on the X-ray below the docking is completed and the site compressed - bent olive wires. All struts still very tight.
02 May 2017
Everything under control and progressing well. Docking was successful and position is maintained.
