Epiphysiodesis technique and rotating partial prosthesis, with preservation of the tibial growth physis, in osteosarcoma of the femur.
The path of the nail crossing the epiphyseal line is correct and is in accordance with the technique used. The presence of the nail may cause concern regarding the possibility of interference with the growth of the physis, as it is a little known technique, but this does not occur.
Careful passage of this 1.0 cm diameter rod, protected by a non-cemented polyethylene “shirt”, does not block the growth cartilage.
It can be seen that the proximal physis of the tibia continues its growth, without blockage, despite having received at its central point the passage of the rotating tibial component, protected by the polyethylene shirt, figure 155.
This growth is evident, especially if we compare it with figure 130, from 06/16/2015, four months earlier.
The red arrow points to the scar where the growth plate was. The white arrow points to the current position of the growth plate. The yellow bar marks how much this bone segment has grown. On this occasion we recommend epiphysiodesis to control the discrepancy.
