Hi Jimmy,
Leg lengthening procedures are possible and are done in selected centres. you can expect to gain 5-12 cm through this. However, it a painful procedure and one which is associated with several complications. Dr Amar Sarin at B L Kapur Memorial Hospital Action Cancer Institute, Nova Surgical Center in Delhi is good. Dr Subhash Shalya at Bone Joints Care Foundation of India, A-74, Sarita Vihar, New delhi, 110076 is also very experienced.
Hope this helps
Regards
