Treatment was begun at the age of 6 years for this girl as early treatment has several benefits and allows better integration of the child with its peers at school and play. In this child,   most of the strategies of treatment were used to give her the maximum benefit.

 

X-ray taken during the treatment

After bilateral double level tibial lengthening

Bilateral double level tibial lengthening was done in the tibia. 11 cm of length was achieved in both the legs without any deformities. This is about 110% lengthening as compared to the original length of the fragment.

At the end of the tibial lengthening,
movement in all joints was normal
as was the Lateral Popliteal Nerve function.
3 years after the initial tibial lengthening, these were her body proportions: notice that the arms are reaching only to the level of the top of the thigh, unlike other normals in whom the hands should reach the middle of the thigh.

After arm lengthening .Cross lengthening Patient after final treatment

After lengthening of the arms, this picture shows the restoration of normal body proportions with the hands reaching upto the mid-thigh.

This is the final strategy used in which Cross lengthening was performed with one thigh and the other leg in the first stage and in the second stage this sequence was reversed. This permitted maximum length to be achieved with minimum wastage of time.

 

The other thigh and leg are being lengthened after a gap of about 6-8 months after the completion of the first stage of treatment. Total lengthening achieved in this way: 33 cms
