Some foot deformities are very complex. Often patients will have had several operations in childhood or adolescence to correct the position of the foot but these are not always successful.

Some diseases such as club foot or charcot-marie-tooth disease can result in a curved and rotated foot that looks like the shape of a banana. This is difficult to correct, but is possible with surgery. It does take months for the full correction and takes place in several stages.

Firstly, the deforming forces – particularly one tendon – are moved to help to bring the foot into a better position. The heel bone is broken and reset to make the foot sit flatter on the ground.

After this has healed – this takes several months – you will be ready to have a second stage. This involves an external fixator to rotate the foot into a better position and also to correct the bent shape. This can take several months, but we try to keep the external fixator on the foot for as short a period as possible.

Thirdly, if the ankle persistently points downwards, you may need the external fixator to be altered to bring the foot flat to the ground again.

Even after all of these procedures, there may be some residual deformity, but we hope that you would then be able to put on a normal shoe, possibly with some insoles, but normal shoes nonetheless, which is not possible with a banana shaped foot.
