Thoracolumbar kyphoscoliosis in Larsen's syndrome. A case report.

Severe thoracolumbar kyphosis in Larsen's syndrome is rare. A successful 10-year treatment course, including T2-L4 subfascial rod placement when the patient was 6 years 3 months of age, nine periodic lengthenings, and definitive surgery at age 14 years 4 months is presented. From preoperative to 2-year postoperative definitive surgery, the patient's T1 to S1 spine length increased from 19 to 36 cm. The patient's 83 degrees thoracolumbar kyphosis was transformed to 45 degrees kyphosis and 28 degrees lumbar lordosis, and scolioses of 95 degrees and 65 degrees were reduced to 64 degrees and 50 degrees.
