Nerve entrapments: a 3D anatomical atlas
An educational atlas of the places where the peripheral nerves of the upper and lower limbs pass through osteofibrous tunnels, muscular arcades or fascial planes and may be compressed. Each site has its 3D anatomical plate, the structures that bound it, an ultrasound landmark, the evidence that describes it and the neurodynamic test that loads that nerve. It is educational material and does not replace clinical assessment.
Upper limb
Median nerve: carpal tunnel and pronator
Ulnar nerve: cubital tunnel and Guyon's canal
- Cubital tunnel: ulnar nerve compression at the elbow
- Guyon's canal: ulnar nerve compression at the wrist
Radial nerve: arcade of Frohse and superficial branch
Lower limb
Sciatic nerve: deep gluteal space and ischial region
- Deep gluteal syndrome and piriformis: sciatic nerve
- Sciatic nerve at the ischial tuberosity: 3D anatomy
Tibial nerve: soleal arch and tarsal tunnel
Fibular nerve: fibular neck, ankle and leg
- Common fibular (peroneal) nerve at the fibular neck
- Anterior tarsal tunnel: deep fibular nerve
- Superficial fibular nerve at the crural fascia
Femoral nerve: inguinal ligament and iliac compartment
Saphenous nerve: adductor canal and infrapatellar branch
Sural nerve: lateral retromalleolar region
Posterior femoral cutaneous nerve: infragluteal region
Obturator nerve: obturator canal and adductor planes
