The trial which positively conducts osteotomy and lengthens the shortened leg, has been reported much, but the cases over 40 years old have never been found among them.
We tried to lengthen the lower leg with 46 years old patient who had been complaining of severe rolling of body when he walk, because of both hip joints tuberculosis resulted in ankylosis and shortening of a leg.
The tibia was cut transversely, subperiosteally, leaving periosteum as it was, and it was lengthened one milimeter a day using Katayama-Hirakawa's Apparatus.
Now, one year and seven months tollowing the operation, though slight bending of tibia and sensory disturbance in peroneal nerve region are noticed, walking and balance of body have been remarkably improved. The patient is satisfied to be able to walk very easily.
