In a retrospective follow-up of 64 patients with myelomeningocele and
scoliosis of more than 10 degrees, the development of the scoliosis cu
rve was watched. The mean follow-up was 4.3 years. Most progression of
scoliosis can be expected before 15 years of age. Fifty-four percent
of the patients with scoliosis of 40 degrees or more progressed more t
han 5 degrees per year. Progression was dependent on the scoliosis ang
le. A multivariate model for the prediction of the scoliosis progress
in a 1-year perspective was applied. The model included the current sc
oliosis angle, the age of the patient, the skeletal level of the dysra
phism, and the patient's ambulation capacity.
