Changes in pain scores and walking distance after transforaminal epidural steroid injection in patients with lumbar foraminal spinal stenosis.

Transforaminal epidural steroid injections (TFESI) are widely used in patients with lumbar foraminal spinal stenosis. Previous studies have evaluated the effects of TFESI on lumbar foraminal spinal stenosis using only pain scores. However, no study has evaluated the effect of TFESI on pain scores and walking distance in patients with lumbar foraminal spinal stenosis. This study aimed to assess the effect of TFESI on pain scores and walking distance in patients with lumbar foraminal spinal stenosis stratified according to disease severity. This retrospective study reviewed the medical records of patients who received TFESI for lumbar foraminal spinal stenosis. A total of 128 patients were divided into the moderate and severe groups based on the extent of fat obliteration and the presence of nerve root compression. A significant decrease in the numeric rating scale (NRS) scores was observed in the moderate and severe groups compared with the corresponding baseline values 4 weeks after TFESI; however, the NRS pain scores were lower in the moderate group than those in the severe group. In addition, the proportion of patients who experienced pain reduction (≥50%) was higher in the moderate group than that in the severe group. The moderate and severe groups showed a significant increase in walking distance compared with the baseline values 4 weeks after the treatment. However, the walking distance values did not differ significantly between the moderate and severe groups. Furthermore, the degree of satisfaction was higher in the moderate group than that in the severe group. Lumbar TFESI may reduce pain scores and increase walking distance in patients with moderate or severe lumbar foraminal spinal stenosis. Patients with moderate foraminal stenosis had better pain relief outcomes than those with severe foraminal stenosis.

Serratus anterior plane block with ultrasound-guided hydrodissection for lateral thoracic pain caused by long thoracic nerve neuropathy - A case report.

BACKGROUND: Long thoracic nerve (LTN) neuropathy occasionally occurs in young people who engage in various sports. It may have a traumatic or non-traumatic etiology. The landmark manifestation of LTN neuropathy is scapular winging; however, it can also occur without scapular winging and specific magnetic resonance imaging findings. CASE: An 18-year-old male complained of right-sided lateral chest pain for 7 months. He was treated with medication, trigger point injection, and physical therapy but showed no improvement. Electromyelogram findings suggested LTN neuropathy in the right lateral chest. We performed a serratus anterior (SA) plane block with ultrasound (US)-guided hydrodissection and achieved pain relief. CONCLUSIONS: We report the successful treatment of LTN neuropathy with an SA plane block and US-guided hydrodissection.

Changes in pain scores and walking distance after epidural steroid injection in patients with lumbar central spinal stenosis.

ABSTRACT: Lumbar spinal stenosis is a common degenerative disorder that is characterized by pain and neurogenic claudication. Previous studies have evaluated the effects of an epidural steroid injection (ESI) on spinal stenosis, based on changes to the spinal canal diameter.This study aimed to examine the impact of the ESI on pain scores and walking distance in patients with lumbar central spinal stenosis, stratified based on disease severity, which was graded according to the degree of cauda equina separation.We reviewed the medical records of patients who received the ESI for lumbar spinal central canal stenosis. A total of 128 patients were divided into moderate and severe groups, based on the degree of cauda equina separation.Relative to baseline values, 2 weeks after the ESI, the moderate group showed a significant decrease in the numeric rating scale (NRS) scores and an increase in walking distance. Meanwhile, the severe group showed a significant decrease in the NRS scores and no significant change in walking distance. The moderate group had lower NRS scores and a longer walking distance than did the severe group 2 weeks after the ESI. The proportion of patients with improved levels of satisfaction was higher in the moderate group than in the severe group.Lumbar interlaminar ESI may reduce pain scores and increase walking distance in patients with moderate lumbar spinal central canal stenosis. Patients with moderate spinal stenosis achieved better outcomes than did patients with severe stenosis.
