All patients underwent direct decompression and neurolysis of the L4 and L5 nerve roots via the single-incision, intrapelvic, extraperitoneal pararectus approach. Results In all patients, the L4 and L5 nerve roo
In severe cases, an L4 disc herniation may impinge on multiple traversing nerve roots. The L5 and S1 nerve roots are included in this. This means that the spine and numerous nerve roots can be pinched by a single slip disc. Due to nerve root impingement and spinal cord compression, L4–...
and the CSA of the ES muscle at L4–L5 was smaller than that in normal people. Although the causal relationship between paravertebral degeneration and LDH has not been established, it is generally believed that compression of nerve roots causes paravertebral degeneration. In LDH patients with Zone...
Below the L1 level the spinal cord consists of individual nerve roots within the dural sac known as the cauda equina (horse's tail).The individual nerve roots travel through the interverebral foramen, which is the space formed by adjacent pedicles. 2. Prolapse of intervertebral disc ...

General anesthesia decreases intraoperative stress, but surgeons may not be sure whether they injure nerve roots. Free-run electromyography may protect nerve roots that are thought to be in danger from surgery. Patients with L4L5 or L5S1 lumbar disc herniation were treated with IELD. EMG was ...
SUMMARY OF BACKGROUND DATA: The L3 and L4 nerve roots innervate the quadriceps; therefore, quadriceps weakness may be a consequence of L3 or L4 radiculopathies. There are no standardized or validated methods to evaluate quadriceps strength in the clinical office setting. This may lead...
