Today is my clinical day- so another one
Have you started using NS-RADs yet?
Here is one- ACL and posterolat corner injury, partial pcl inj- likely d/l- CPN repair- still foot drop.
Much more seen on imaging- now needs nerve transfers in leg
Common peroneal nerve: Focal enlargement of the nerve in the posterior thigh above the adductor canal on the first cut, also seen on 3-D images suggesting a proximal neuroma in continuity/enlarged nerve, partially imaged.
After separation from the sciatic sheath, the common peroneal nerve is near normal size with diffuse increased signal. At the level of the femoral epiphysis, just above the knee joint line, under the posterior medial thigh fascia, there is a second neuroma in-continuity, possibly at the site of prior neurolysis and graft placement.
There is diffuse enlargement of the deep and superficial peroneal nerves along the course of the common peroneal nerve with more signal abnormality of the deep peroneal nerve.
Tibial nerve: Mildly increased signal proximally to the bifurcation, otherwise normal
Medial and lateral sural cutaneous nerves: Normal
IMPRESSION: Common peroneal more than tibial neuropathy changes with neuromas in continuity as detailed
NS-RADS: Nerve: PI3 – Postintervention/surgical cases, definitely persistent or worsening neuropathy, Muscle: M2 – Muscle edema-like signal and minimal fatty replacement or mild atrophy
