Residual kyphos'ıs secondary to old and healed cases of spinal tuberculosis causing disability are stili encoun-tered. The standart double stage operation with anterior osteotomy and posterior instrumentation and correction has its drawbacks. We planned to employ the Egg-shellprocedure to treat lumbar Pott's kyphosis in a single stage operation. Three patients with lumbar Pott's kyphosis (at L1, L2-3 and L5 respectively) were operated with a single stage posterior approach by evaluation of the wedged vertebral body via the transpedicular route. After the inser-tion of pedicular screws above and belovv, correction was obtained by coliapse of the Egg-sheiled segment. There were no neuroogical complications. The pre- andpostoperative kyphosis angles were as follows: 97° - 37°, 42°, 37° - (-10°) respectively. The average correction was 53,3° mean. The patients were mobilized carefully within the first postoperative week with light orthoses. They healed uneventfully and returned to active social life vvithin six to nine months.

Conciusion:

The Egg-shell procedure is a saf e and reliable method in the correction of short segmented, sharp kyphosis like the deformities seen in Pott's disease. İn this single stage operation the patient encounters less mor-bidity and early fusion is usually obtained.
