As you can see on the images below, the injury was pretty significant, high energy trauma with an open distal femoral fracture (Gustilo-Andresen 3B).

Definitive fixation was done as per our protocol above.

Post operative X-rays are self explanatory.

We will wait for 6 weeks before we do anything with the bone defect. One of the reasons is infection and the second one is spontaneous bony activity in the defect which is not as rare as someone would expect.

Apart from pain in the thigh at the time of distraction everything else is going well. Clinically no sign of infection.
If you compare the plate shape prior the transport and now you will see a significant bent suggesting a significant force on the plate. Exactly what we usually see.

Good progress but there is a significant strain on the plate visible on the X-ray. I can only suspect that the force required for callus distraction can vary from patient to patient. I can see in the other patients that those plates are not loaded so much. We will probably have to consider augmentation of the plate.
For now I cannot see any sign of failure of the construct, eminent or waiting to happen, apart from the bend in the plate.

Precice nail reached its final position in compression. To continue with the bone transport we have to:
Because we know that higher the number of procedures (opening of the skin), higher the chance of deep infection, we decided to proceed with percutaneous locking-unlocking and two anaesthetic sessions. First one first thing in the morning and second late in the afternoon leaving enough time to expand the nail using standard magnet.
Everything went extremely well. Exactly as planned. It did take some preparation to coordinate theatre time, distraction on the ward and reprogramming the magnet every 2.5mm due to the software limitations, but it was well worth it. Only three small wounds in combined length less than 2 cm.

So far everything well. Flexion contracture is gradually improving.
