โซ๏ธ Calling SCN, a nerve, is itself is MISNOMER.
โซ๏ธ It is a composite neural complex containing TN + CPN within a paraneural envelope.
โซ๏ธ TN & CPN are distinct nerves.
โซ๏ธ Each has its own epineurium, fascicles, perineurium.
โซ๏ธ Therefore:
SCN paraneural boundary โ TN/CPN epineurium.

โซ๏ธ Extraparaneural โ outside the SCN paraneural envelope.
โซ๏ธ Subparaneural โ inside that envelope.
โซ๏ธ Yet injectate may remain outside both TN & CPN epineuria.

โซ๏ธ Thus, spread may look โintraneuralโ relative to the composite SCN while remaining extraneural to its component nerves.
โซ๏ธ Nerve swelling on ultrasound โ proof of intraepineurial TN/CPN injection.
โซ๏ธ Previous MRI/sonographic studies have already demonstrated this important terminologyโanatomy mismatch.
โIntraneuralโ means little unless we specify WHICH boundary has been crossed.

โซ๏ธ Cross TN epineurium โ intraneural to TN.
โซ๏ธ Cross CPN epineurium โ intraneural to CPN.
โซ๏ธ Remain outside fascicles โ intraneuralโextrafascicular.
โซ๏ธ โSubepineurialโ therefore belongs within this broad extrafascicular domain.
โซ๏ธ Cross perineurium โ intrafascicular/endoneural.
Paraneural โ Subparaneural โ Subepineurial/Extrafascicular โ Intrafascicular

โซ๏ธ Paraneural/subparaneural spread was universal.
โซ๏ธ Deeper subepineurial and extrafascicular spread occurred variably.
โซ๏ธ No intrafascicular spread was demonstrated.
But important limitations remain:
โ ๏ธ No histology โ exact microscopic boundary crossing unconfirmed.
โ ๏ธ Needle-tip position uncertain โ deeper dye cannot automatically prove sequential inward migration.
โ ๏ธ No pressure monitoring โ mechanism of tissue separation remains unknown.
โ ๏ธ Latex + cadaver โ LA + living nerve.
โ ๏ธ Very small sample โ TNโCPN differences remain hypothesis-generating.
โ ๏ธ โSubepineurialโ & โextrafascicular intraneuralโ may represent different depths of the same continuum, not completely separate compartments.
โ ๏ธ Absence of fascicular dye โ proof of clinical safety.
Most importantly:
The study demonstrates DISTRIBUTION, not necessarily TRAJECTORY.

โซ๏ธ Much of the reassuring โintraneuralโ literature comes from the popliteal SCN.
โซ๏ธ Prior clinical, MRI, sonographic & cadaveric studies have shown that:
apparent SCN intraneural spread may actually be subparaneural or extrafascicular.
โซ๏ธ Their findings therefore cannot be automatically extrapolated to ordinary single-epineurial peripheral nerves.
The โsafe intraneural SCNโ narrative may partly be an ANATOMICAL NOMENCLATURE problem.
๐ก ๐๐๐ฌ ๐ง๐๐๐๐๐ช๐๐ฌ๐ฆ
โซ๏ธ Popliteal SCN โ simple single-epineurial nerve.
โซ๏ธ Think TN + CPN within a specialised paraneural complex.
โซ๏ธ Extraparaneural โ subparaneural.
โซ๏ธ Subparaneural โ intraepineurial TN/CPN.
โซ๏ธ SCN spread may appear โintraneuralโ while remaining extraneural to TN & CPN.
โซ๏ธ Subepineurial = intraneuralโextrafascicular to the individual nerve.
โซ๏ธ Intraneural โ intrafascicular.

โSciatic Nerve: The Great Pretender!โ

#MyRATips
#TipOftheDay
Tip of the Day:
It looks like one big nerveโbut itโs actually a dual-nerve bundle hidden in a sheath.
โก๏ธ Two Nerves, One Sheath
The โsciatic nerveโ is a paraneural compartment (Vlokaโs sheath) containing Tibial Nerve (TN) and Common Peroneal Nerve (CPN).
โก๏ธ Split by CoโCu Septum (ComptonโCruveilhier)
Inside the sheath, TN & CPN are separated by the CoโCu septumโa fascial divider that keeps them anatomically distinct, enabling selective nerve blocks.
โก๏ธ No Common Epineurium
The sciatic nerve has no unified epineuriumโeach component nerve retains its own protective layers, allowing for targeted or sparing techniques.
โก๏ธ Innervation Above the Knee (No innervation by SCN)
TN: semimembranosus, semitendinosus, long head of biceps femoris, ischial part of adductor magnus
CPN: short head of biceps femoris.
โก๏ธ Articular Supply to Hip & Knee
Both TN & CPN give sensory branches to hip and knee joints, making sciatic blocks effective for posterior joint pain.
โก๏ธ Regional Anesthesia Insight
To block the sciatic nerve effectively, use subparaneural injectionโinside Vlokaโs sheath, but outside the nerves.
It may look intraneural, but when done right, itโs safe and essential.
Bottom Line:
The sciatic nerve is a fascial illusionโtwo nerves, one sheath, divided by a septum.
Understand the architecture. Respect the layers.
Block with precision.

Vascular dysfunction is at the onset of oxaliplatin-induced peripheral neuropathy symptoms. Brunet lab identifies that vasodilators can alleviate neuropathic symptoms, highlighting the importance of vascular health in OIPN treatment. @CirbCdf @SoniaTaib

#Sciatica pain can be really excruciating!
The best way to alleviate most sciatica pain is to do โany stretch that can externally rotate the hip to provide some relief.
