. The aim of this study was to compare the accuracy and efficacy of sonographically guided lumbar periradicular injections through in-plane or out-of-plane approach techniques for patients with unilateral lower lumbar radicular pain. The feasibility and accuracy of these techniques were studied by means of computed tomography (CT). . A total of 46 patients with chronic unilateral lumbar radicular pain were recruited and randomly assigned to either the in-plane or out-of-plane injection group. A mixture of 3 mL 1% lidocaine and 7 mg betamethasone was injected. The visual analog scale (VAS) was used to assess pain before and after treatment. . The pain intensity, as measured by VAS, significantly decreased in both in-plane and out-of-plane injection groups. . The sonographically guided periradicular injections are feasible and effective in treating lumbar unilateral radicular pain.

Intervertebral thoracic disk herniation (TDH) is a rare occurrence and presents with a wide variety of symptoms. Errors in diagnosis are thought to be frequent due to the variable clinical presentations. We herein present two unusual cases of TDH presenting with abdominal pseudohernias, abdominal pain, and hypoesthesia along the T11-T12 dermatomes due to TDH at the same level.

Objective: Transforaminal epidural steroid injection (TFESI) is highly effective in alleviating radicular back pain. While predictive factors for TFESI treatment outcomes have been previously studied, there is a lack of data on the relationship between facet joint degeneration and TFESI efficacy. This study is aimed at studying the impact of facet joint degeneration on TFESI treatment outcomes for unilateral radicular pain.

Case: A 73-year old man who underwent previous L2-S1 decompression presenting with new right radicular leg pain. Imaging suggests a large central disk herniation at L1-2 with possible intrathecal extension requiring surgical decompression. When positioned prone on a Jackson frame, neuromonitoring motor signals became diminished, and thus, the case was aborted.

Sciatica, often characterized by low back pain (LBP) radiating to the leg, is a challenging condition to manage, especially when conventional therapies fail. We present the case of a 27-year-old man who suffered from persistent low back pain with left-sided radicular symptoms. Despite treatment with numerous oral medications, including acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), gabapentinoids, and muscle relaxants, his symptoms persisted and intensified.
