They result in symptoms when they disrupt the function of the nerve from which they arise, or cause mass effect on adjacent structures. In this case, symptoms resulted from compression of the cauda ...

On the T2-weighted images, CSF is bright. Note the large disk herniation between the L3 and L4 vertebral bodies. On the axial scans, the disk herniation essentially obliterates the CSF (right upper ...

The L1 to L4 lumbar medial branch nerves course over the base of the transverse process at the junction of the superior articular and transverse processes.

For instance, if the patient has lumbar stenosis from the L3 to L5 levels, the L4 spinous process is removed first. Then the spinous process of L3 and L5 are partially removed.

Dear Dr. Roach: I suffered a lower back injury in 2001, with crushed and bulging discs in the L2, L3, L4 and L5 vertebras. After over a year of physical therapy and drugs, my pain doctor tried an ...

Medial branch blocks can be easily over-reported if spinal anatomy is not understood or the actual procedure is not detailed. A procedural note stating, “medial branch blocks of L3, L4 and L5 nerves” ...

Clinical syndromes reflect compression of the superiorly exiting nerve root and ganglion; ie an L4–L5 far lateral disc produces a L4 root syndrome.

Two cages at L3-L4 is 22851, one cage at L3-L4 and one at L4-L5 is 22851×2. In many instances bone graft material may be packed into a cage, the bone graft is separately reported. CPT notes and CPT ...

This week we are going discuss another obscure nerve compression syndrome, this time of the leg—meralgia paresthetica. Meralgia paresthetica is also known as lateral femoral cutaneous nerve ...

If this pressure pinches the L3 or L4 nerve root in the lumbar spine, it can cause anterior thigh numbness and tingling.
