What’s wrong with my back? I was born with an innate variance of the lowest lumbar segment. (Where your lumbar spine meets the sacrum) The lowest lumbar segment has bilaterally enlarged transverse processes, with the right being the larger and fused to the sacrum. The left side forms a pseudo-joint or pseudo-articulation with the sacrum. Creating a “wrong joint” (that does not contain a disc or cartilage) Having symptoms of this congenital abnormality is known as Bertolotti syndrome. (In Australia, I’ve found doctors don’t use this term, calling it Lumbosacral Transitional Vertebrae (LSTV) for short.) Bertolotti syndrome can cause back pain, radicular symptoms over time due to inflammatory spread, hip tightening, and the Groin, pelvis, abdominal muscles, front thighs and back thighs, and muscles of the lower back. Sitting becomes more and more difficult over time. Rotational or twisting movements cause irritation and bend forward as this pulls the sacrum. There are several non-surgical treatment options and two surgical options. Although there isn’t much high-quality evidence that surgery is effective in treating Bertolotti syndrome. I will go into more detail about the treatment options in another post.
