Floor of ulnar tunnel & relationship of neurovascular structures👍

3 types of Guyon canal syndromes:

Type 1
Proximal to bifurcation of nerve=Mixed motor & sensory

Type 2
Surrounds deep motor branch=Motor only

Type 3
Surrounds superficial sensory branch=Sensory only

Measuring depth of Lateral Femoral Notch Sign (LFNS) by Lat Knee Radiograph is reliable predictor for Dx of ACL injury in ACUTE setting & can be used by clinicians in patients with acute knee trauma.

Muscles that make up the anterior compartment of thigh are sartorius & quadriceps femoris muscles (rectus femoris,vastus lateralis, vastus medialis, vastus intermedius).

Psoas major & iliacus muscles also pass into the upper aspect of the anterior compartment.

Differentiating between intersection syndrome and de Quervain’s disease
and identification of ulnar styloid process and extensor carpi ulnaris is very important & in this regard clinical exam is very helpful 👍

With regard to rotator cuff tendon tears, the terms “partial-thickness”(partial) and “full-thickness” (complete) do NOT state (as is often erroneously assumed) whether the rupture involves the entire tendon or only a part of the tendon!

Partial-thickness vs Full-thickness Tears

Peripheral dermatomes & key muscles of the most important lumbosacral
nerve roots. However, keep in mind that the muscles also receive contributions from other nerves (e.g., the extensor digitorum longus is innervated mainly by L5, but also from L4 and S1).

The pudendal nerve carries sensory, motor, and sympathetic fibers. The pudendal nerve is derived from the ventral rami of the S2,S3 & S4.The nerve passes through the piriformis muscle, where it is joined with the pudendal artery & vein...

Movement of C-spine involves combination of uncovertebral & zygapophyseal motion.

During neck flexion,zygapophyseal & uncovertebral joints glide in a combined superior,lateral& anterior direction.

During neck extension, joints glide in a combined inferior,medial&post direction
