Another one with report for your learning as lots of folks want it
Post old acetabular fracture- right leg bucking and anterior pain- spine surgery versus nerve consideration- EMG with some bogus radiculopathy report as usual
Nerves Lumbosacral plexus: Size: Normal. Signal: Normal. Course: Normal.
Sciatic nerve: Size: Normal. Signal: Normal. Course: Normal.
Femoral nerves: Size: Normal. Signal: Normal. Course: Normal.
Obturator nerves: Size: Diffusely thickened on the right. A small neuroma in-continuity at the site of fracture, adherent to the adjacent fracture site. Signal: Increased signal on the right. Course: Mildly altered on right – stuck at fracture healing site.
Other specific nerves in question: Lateral femoral cutaneous nerves are normal.
