A Change in Global Sagittal Alignment after Transforaminal Epidural Steroid Injections in Lumbar Spinal Stenosis.

Patients' functional adaptation to pain can affect global sagittal alignment. This study evaluated the short-term spinal sagittal alignment change after transforaminal epidural steroid injection (TFESI) in lumbar spinal stenosis patients. Patients with lumbar spinal stenosis who underwent TFESI were retrospectively examined. Clinical outcomes were assessed using the Visual Analog Scale (VAS) and Oswestry Disability Index (ODI). Before and two weeks after the intervention, whole-spine lateral standing view radiographs were taken. Radiographic parameters including the Sagittal Vertical Axis (SVA), C2C7 Cobb, Thoracic Kyphosis (TK), Lumbar Lordosis (LL), Pelvic Incidence (PI), Pelvic Tilt (PT), Sacral Slope (SS), and Lumbopelvic Mismatch (PI-LL) were measured. Ninety-nine patients (mean age 64.3 ± 9.2 years) were included in this study. Both VAS and ODI outcomes were statistically improved after two weeks of intervention. Radiographic parameters showed that SVA, PT, and PI-LL mismatch were significantly decreased, while C2C7 Cobb, TK, SS, and LL were significantly increased after the intervention. SVA was improved by 29.81% (52.76 ± 52.22 mm to 37.03 ± 41.07 mm, p < 0.001). PT also decreased significantly from 28.71° ± 10.22° to 23.84° ± 9.96° (p < 0.001). Transforaminal epidural steroid injection (TFESI) significantly improves VAS, ODI, and global sagittal parameters in lumbar spinal stenosis patients.

Efficacy of Preemptive Analgesia on Tourniquet and Postoperative Pain Relief in Open Carpal Tunnel Release: A Prospective Randomized Control Trial.

PURPOSE: Preemptive analgesia has been used to reduce postsurgery pain and improve patient satisfaction. The effectiveness of multimodal preemptive analgesia in open carpal tunnel release under local anesthetic with a tourniquet is still debated. This study aimed to determine the effectiveness of preemptive analgesia on the postoperative tourniquet site and the surgical site. METHODS: A total of 44 patients were randomly assigned to one of 2 groups. An experimental group was given 300 mg of gabapentin, 200 mg of celecoxib, and 500 mg of acetaminophen 2 hours before surgery. Placebos were given to the control group. All surgeries were done under local anesthetic by a specialist hand surgeon. A tourniquet was inflated to the recommended pressure. The outcomes included the immediate postoperative tourniquet site pain scores, surgical site pain scores (at 1, 6, 12, 18, and 24 hours after surgery), and acetaminophen consumption in the first 48 hours. RESULTS: The immediate postoperative tourniquet site pain score in the experimental group was significantly lower than in the placebo group. Although the surgical site pain score in the experimental group was significantly lower than the placebo group at 1, 6, 12, and 18 hours after surgery, these differences were not clinically significant. In addition, there was no statistically significant difference in surgical site pain score at 24 hours after surgery. The amount of acetaminophen consumed during the first 48 hours after surgery was significantly lower in the experimental group than in the placebo group. CONCLUSIONS: Multimodal preemptive analgesia effectively reduced immediate postoperative pain at the tourniquet site in open carpal tunnel release. It also reduced postoperative acetaminophen consumption. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

A comparative study of supine traction, supine side-bending radiographs, and supine MRI to determine coronal flexibility in degenerative lumbar scoliosis patients.

PURPOSE: The purpose of this study was to compare curve correction in degenerative lumbar scoliosis using supine traction radiographs, supine side-bending radiographs, and supine MRI. METHODS: A prospective analysis of Cobb angles from patients diagnosed with degenerative lumbar scoliosis who underwent supine traction radiography (TR), side-bending radiography (SB), and supine MRI. The Cobb angles at thoracic (T), thoracolumbar/lumbar (TL/L), and lumbosacral (LS) levels were measured, and the curve correction in percentages compared with standing AP radiography was calculated as corrective flexibility. Differences in curve correction were analyzed. RESULTS: In total, 33 patients with an age range of 50-80 years were eligible for inclusion. Traction radiography provided the greatest accuracy in curve correction, with a significant difference from side-bending radiography and supine MRI in T, TL/L, and LS levels (P < 0.001). The difference between side-bending radiography and supine MRI in TL/L and LS levels was not significant (P = 0.721, P = 0.654, respectively). A moderate correlation was found between the corrective flexibility of TR and SB at the T level (0.563, P = 0.001), a strong correlation was observed between the corrective flexibility of TR and SB at the TL/L level (0.709, P < 0.001), and at the TL/L level, a moderate correlation was identified between TR and supine MRI corrective flexibility (0.425, P = 0.014). CONCLUSIONS: Traction radiographs significantly outperformed side-bending radiographs and supine MRI in terms of access curve flexibility in degenerative lumbar scoliosis.

Effect of Single-Dose Preemptive Systemic Dexamethasone on Postoperative Dysphagia and Odynophagia Following Anterior Cervical Spine Surgery: A Double-Blinded, Prospective, Randomized Controlled Trial.

Background: The efficacy of preoperative dexamethasone in anterior cervical discectomy and fusion (ACDF) to reduce dysphagia and odynophagia remains controversial. This study evaluated the effect of a single dose of intravenous dexamethasone given as preemptive analgesia in the ACDF procedure. Methods: A total of 64 patients aged 18 years or over were randomized into two groups. The experimental group received dexamethasone 10 mg intravenously before surgery for 60 minutes, and the control group received normal saline. One surgeon operated on all patients. The Bazaz score and visual analog scale (VAS) for odynophagia were measured at 0 hour, 24 hours, 48 hours, 72 hours, and 2 weeks postoperatively. Prevertebral soft-tissue swelling (PSTS) and the modified Japanese orthopedic association (mJOA) score were measured preoperatively and 2 weeks postoperatively. Results: The Bazaz scores at 0, 24, 48, and 72 hours after operation were significantly lower in the dexamethasone group than in the placebo group (p < 0.001, p < 0.001, p < 0.001, and p = 0.004, respectively). The VAS scores of the dexamethasone group were significantly lower than those of the placebo group at 0, 24, 48, and 72 hours after surgery (all p < 0.001), but there was no significant reduction in the Bazaz score and VAS score at 2 weeks postoperatively. There was no difference in PSTS and mJOA preoperatively and 2 weeks postoperatively. Conclusions: A single dose of intravenous dexamethasone used preoperatively in single-level and multilevel ACDF can significantly improve symptoms of dysphagia and odynophagia early on postoperatively.
