Lumbar Disc Herniation with Foot Drop

Diagnosis

Chronic, partially calcified lumbar disc herniation at the L4–L5 level on the right side, complicated by severe right-sided foot drop (paresis). Due to the nerve deficit, the foot slaps against the ground while walking and cannot be dorsiflexed (raised upward). Conservative management yielded significant pain relief; however, weakness and foot drop persist.

Expert Opinion by Spine Specialist Dr. Andrey Bitter:

The primary clinical challenge for the patient is the intervertebral disc herniation at the L4–L5 level on the right. This lesion compresses the right L5 nerve root, directly causing the foot drop. Surgery is unequivocally indicated due to the acute motor deficit. While neurological recovery of motor function in the foot may take time, lower back and radiating leg pain should subside immediately following surgery. The immediate objective is surgical decompression of the compressed nerve root via herniated disc removal.

Patient’s Inquiry:

I was offered several surgical options locally, including endoscopic nucleoplasty, as well as disc correction with either dynamic or static stabilization via an anterior approach. Which surgical technique do you recommend?

Doctor's Answer:

Your imaging indicates that this is a chronic lesion, meaning the herniated fragment has likely undergone partial calcification (ossification). Calcified herniations of this nature are best addressed using a microsurgical approach rather than an endoscopic technique. Nucleoplasty is entirely contraindicated here, as the herniation is sequestrated—meaning the disc material has completely extruding beyond the outer annulus fibrosus.

Given that your imaging demonstrates widespread degenerative disc disease and osteochondrosis throughout the lumbar spine, some overly aggressive surgeons might propose 'preventative' spinal fusion with screws to allegedly prevent recurrent herniation. While fusion would indeed prevent a recurrence at that specific level, adjacent spinal segments would absorb excessive biomechanical stress due to restricted mobility. This accelerated adjacent segment degeneration often necessitates major revision surgery within 5 to 10 years.

I strongly advise a minimally invasive target-oriented intervention, followed by clinical observation. Lumbar total disc replacement (arthroplasty) is strictly contraindicated due to significant degenerative changes in the facet joints. Furthermore, an anterior approach (through the abdomen) in male patients carries serious risks of postoperative retrograde ejaculation and major vascular injury (e.g., aortic involvement)—risks that are medically unjustified in your case. The criteria for disc replacement are simply not met.

Treatment Performed & Clinical Outcome

A microsurgical procedure was successfully conducted to resect the heavily calcified L4–L5 disc herniation, alongside neurolysis (decompression) of the right L5 nerve root.

The postoperative recovery was uneventful. The patient was mobilized under clinical supervision and surgical drains were removed on the first postoperative day. Hospital discharge took place on day 6 post-surgery.

Given the persisting motor weakness in the right foot, temporary use of an ankle-foot orthosis (AFO / splint) maintaining dorsiflexion was recommended to protect against accidental joint twisting or fractures. Intensive physical therapy and targeted calf and foot muscle rehabilitation were prescribed.
