A study of the paraspinalis and thigh muscles before and after spinal surgery

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.
