Dwarf is someone who is shorter than his/her peers in the same age, or the height is below 1.4 -1.5 meters in adulthood. There may be a delay in growth until the age of 16 in children.

In addition; some diseases such as diabetes, congenital heart diseases and renal diseases may cause defects in growth and development.

Fractures, bone inflammations, and tumors have significant importance in bone shortness. The patients cannot use their limbs due to main causes or accompanying situations. Therefore, the bone lengthening is required. Both limb lengthening and height lengthening in dwarfs are performed by the method which was introduced to the world in 1950s by a Russian Orthopedician Dr. Ilizarov. This method enables 10cm lengthening in a single procedure and the height may be lengthened 35-40 cm after several procedures.

1 mm bone lengthening per day is enabled by attaching a circular shaped device to the wire and screws, which are threaded through the bones.
