Patient: a 72-year-old woman. BMI: 26.6 kg/m².

Clinical findings

Pain along the anterolateral right thigh and front of the right lower leg had lasted more than six months. Preoperative intensity was 8–10/10 on the VAS. Right knee extension weakness was present, graded 4/5 on the MRC scale.

The patient had received repeated courses of conservative treatment. She had not previously undergone lumbar spine surgery.

Preoperative imaging

MRI: right-sided extraforaminal L4–L5 disc herniation. Clinical diagnosis: right L4 radiculopathy.

At one week, pain intensity was 4/10 on the VAS. Right knee extensor strength remained 4/5 on the MRC scale.

Neuropathic symptoms appeared during the same period: burning pain, tingling and pain on touch. In the author's clinical assessment, these were related to prolonged preoperative nerve compression. Pregabalin was prescribed, and these symptoms decreased while taking it.
