French researchers have studied the imaging of spinal and thigh muscles in patients with SMA before and after corrective spinal surgery:
- 20 patients with type II SMA participated in the study,
- two magnetic resonance imaging (MRI) scans of the areas of interest (thighs and spine) were performed before and after corrective spine surgery, five years apart,
- this surgery was based on a minimally invasive technique involving the implantation of rods extending from T1 to the sacrum,
- fatty infiltration of most of the thigh muscles was the rule preoperatively,
- after surgery, only the couturier and spinous-transverse muscles continued to deteriorate.
The authors highlight the relative preservation of the other muscles and the interest of this minimally invasive technique, which is less damaging, in SMA.
