Article Abstract
Posterolateral spinal fusion is the standard surgical approach for patients with degenerative disc disease. In our previously published article, we reported a 5-years follow-up of a phase I/II clinical trial in patients undergoing spinal fusion with autologous mesenchymal stem cells (MSCs) embedded in tricalcium phosphate. In the current manuscript, we have updated the results with a 10-year follow-up, the longest reported to date in this setting. After clinical and radiological evaluation, safety of the procedure was further confirmed in all 11 treated patients, with no evidence of tumor, infection, inflammatory reaction, or heterotopic ossification related to the administration of MSCs. Regarding clinical efficacy, low back pain and radicular pain (both assessed by the visual analogue scale-VAS), and the Owestry Disability Index remained significantly lower compared to pre-intervention. Radiologic evaluation demonstrated spinal fusion in all cases, improving over time. Finally, quality of life improved significantly also during follow-up. In summary, the use of tricalcium phosphate-embedded autologous MSCs with lumbar posterolateral arthrodesis is safe and potentially provides long-term benefits for 10 years.

An analysis of different modalities of bone mineral densitometry evaluation in cage subsidence in anterior cervical discectomy and fusion.
Front Surg
December 2024
Department of Spinal Surgery, The Third Hospital of Hebei Medical University, Shijiazhuang, China.
Objective: To compare the effectiveness of different measurement methods on bone miner density (BMD), including cervical HU of CT, MRI-based cervical vertebral bone quality (C-VBQ), and value of DEXA, for predicting cage subsidence after single-level ACDF.
Methods: This is a retrospective study, and patients who underwent single-level ACDF from June 2019 to June 2022 were recruited. We collected preoperative total segmental vertebral height (pre-TSVH), cage subsidence height, cervical angle (CA), T1-slope, straight or reverse cervical curvature, mean HU value of C3-7 (C-HU), mean HU of segment (seg-HU), C-VBQ, segmental C-VBQ (seg-VBQ), and total lumbar value ( value).

Effect of Nicotine Replacement Therapy on Perioperative Pain Management and Opioid Requirement in Abstinent Tobacco Smokers Undergoing Spinal Fusion: A Double-blind Randomized Controlled Trial.
J Neurosurg Anesthesiol
December 2024
Departments of Anaesthesiology, Pain Medicine and Critical Care.
Background: Smoking negatively impacts postoperative outcomes but acute abstinence from smoking during hospitalization can increase postoperative pain, lower pain thresholds, disrupt pain management, and trigger hyperalgesia due to abrupt nicotine withdrawal in tobacco users. Nicotine replacement therapy has been recommended to minimize these complications. We hypothesized that a high dose (21 mg/24 h) transdermal nicotine (TDN) patch would reduce postoperative pain and opioid requirements.

Background: Congenital scoliosis with progressive potential is a controversial subject in early-onset spinal deformities. The presence of a hemivertebra may produce severe spinal deformities. The evolution of a scoliotic curve in these cases is unpredictable and requires careful follow-up dependent on multiple variables, such as the location of the hemivertebra, the age of the patient at the time of diagnosis, and the degree of deformity already present in both sagittal and frontal planes.
