Classic Bertolotti’s syndrome is a movable painful articulation of the transverse-alar articulation of L5-S1 on one side. You have a fusion of that articulation {“left sided partial sacralization of l5 with fusion of the left l5 transverse process with the sacral ala”). This leads to overload of your sacroiliac joint and “arthritis” on the opposite side (“advanced right sided sacroiliac joint osteoarthritic changes”).
You also have degenerative changes above. All could lead to various symptoms.
