The study was done to find out the relationship between severity of pain, JOA back
score and the level of serum 25-hydroxy calciferol in the patients who had flail back
surgery syndrome. There were 28 flail back surgery patients in our study. All have
been treated with intensive conservatively for at least 6 months. Moderate to severe
pain and low back score, VAS > 5 and the score < 15.0 were observed. After vitamin
D3 was given, the patients were re-examined at 3 and 6 months. Visual analog scale
and the score were recorded at before and after the study. All had serum 25-hydroxy
calciferol below 30 ng/ml. After vitamin D3 was added in the conservative program for
3 months, all patients have increased in serum 25-hydroxy calciferol and 21/28
became normal, > 30 ng/ml. Significant pain reduction and improvement in back
score, VAS < 3 and the score > 15 were found in 19/28 patients. At 6 month follow
up, all patients had normal serum 25-hydroxy calciferol and 22/28 patients have
significant pain reduction and improvement of the score. Vitamin D is one of the most
interesting factors influencing pain and loss of function in flail back surgery
syndrome.
