Osteoid osteoma is a benign bone-forming tumor that commonly affects young adults and often presents with severe nocturnal pain responsive to NSAIDs. While surgical resection is curative, lesions located in the spine, particularly near critical structures such as the vertebral artery and spinal cord, pose substantial diagnostic and surgical challenges. We report a case of a 24-year-old male with intractable night pain caused by an osteoid osteoma located at the superior margin of the right T1 pedicle. Despite extended NSAID therapy, the patient’s symptoms persisted. Multimodal imaging including MRI, CT, and PET-CT confirmed the diagnosis and revealed the lesion’s proximity to vital neurovascular structures. To minimize morbidity, we employed intraoperative O-arm navigation integrated with preoperative imaging to achieve precise localization and targeted resection through a limited posterior approach. The nidus was successfully excised en bloc without complications. Postoperatively, the patient experienced immediate pain relief and returned to normal activities within days. This case highlights the utility of real-time 3D navigation in managing spinal osteoid osteomas and supports its use as a safe, effective alternative to traditional wide exposure techniques, particularly in anatomically constrained regions of the spine.

Vertebroplasty or kyphoplasty is a widely accepted minimally invasive procedure for treating painful vertebral compression fractures. Although considered safe, rare but serious complications such as spinal subdural hematoma (SDH) can occur, particularly in patients receiving long-term anticoagulation therapy. We present a rare case of spinal SDH following kyphoplasty in a 78-year-old woman with a mechanical aortic valve on chronic warfarin therapy. Anticoagulation was managed perioperatively with warfarin discontinuation and bridging enoxaparin. Postoperative X-ray showed subtle posterior cement leakage. MRI on postoperative day 1 revealed lumbar SDH, which progressed cranially by day 2. The patient remained neurologically intact and was treated conservatively with corticosteroids and temporary suspension of anticoagulation. Follow-up imaging showed gradual hematoma resolution, and she was discharged without deficits. This case suggests the importance of maintaining a high index of suspicion for spinal hematoma in anticoagulated patients, especially when new symptoms or even minor cement leakage are present. Careful perioperative planning, including early imaging and multidisciplinary management, is crucial in such high-risk patients.

Purpose
To report an uncommon case of Opalski syndrome following traumatic C4–C5 facet dislocation with vertebral artery dissection, and to discuss its diagnostic and therapeutic implications.
Materials and Methods
A 60-year-old woman presented after a motor vehicle collision with bilateral upper limb weakness. Cervical X-ray, CT, MRI, and CT angiography revealed C4–C5 facet dislocation and left vertebral artery occlusion. Urgent anterior cervical discectomy and fusion were performed, and the postoperative course was monitored.
Results
Immediate postoperative improvement to 4/5 strength in both arms was noted; however, new left facial numbness appeared at 12 hours and left lower limb weakness with gait ataxia at 48 hours. Brain MRI confirmed left lateral medullary infarction, and aspirin therapy was initiated. At one month, left arm strength recovered to 4/5, but ataxia persisted.
Conclusions
In cervical trauma patients with C4–C5 facet dislocation and vertebral artery injury on initial imaging, the possibility of delayed lateral medullary infarction—particularly Opalski syndrome—should be considered. Prompt brainstem imaging and tailored antithrombotic therapy are essential when new neurologic deficits arise.

Study Design
Retrospective comparative study.
Purpose
To evaluate and compare the clinical outcomes and complication profiles of decompression alone versus decompression with instrumented fusion in elderly patients aged 75 and older with lumbar spinal stenosis. Overview of Literature: Lumbar spinal stenosis is a common cause of disability in elderly patients. The decision between decompression alone and fusion surgery in the geriatric population remains controversial due to surgical risks and comorbidities.
Methods
A retrospective analysis of 121 patients aged ≥75 years treated either with laminectomy alone (n=60) or with posterior lumbar interbody fusion (PLIF, n=61) from April 2016 to December 2022. Baseline characteristics, perioperative parameters, and postoperative outcomes were compared.
Results
There were no significant differences in baseline characteristics. The PLIF group showed longer operative times, greater blood loss, and longer hospital stay, but similar complication rates. Both groups showed significant postoperative improvement in VAS, ODI, and EQ-5D scores.
Conclusions
Decompression alone and fusion surgery both provide substantial clinical benefit in elderly patients with spinal stenosis. With careful selection, fusion may be safely considered even in the elderly.

Purpose
To compare the 3-month outcomes of romosozumab and percutaneous vertebroplasty in patients with acute osteoporotic vertebral compression fractures (OVCFs).
Background
Vertebroplasty provides rapid pain relief in acute OVCFs but carries risks such as cement leakage and adjacent fractures. Romosozumab, an anti-sclerostin monoclonal antibody, promotes bone formation and reduces fracture risk; however, its effectiveness in acute OVCFs remains unclear. Material and Methods: This retrospective study included 84 patients with MRI-confirmed acute OVCFs treated between January 2022 and December 2024. Patients received either monthly subcutaneous romosozumab injections (n=52) or vertebroplasty followed by weekly oral alendronate (n=32). All received daily calcium (500 mg) and vitamin D₃ (1,000 IU). Clinical outcomes were assessed using the Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI), and radiographic changes were evaluated based on anterior vertebral body height at baseline, 1 month, and 3 months.
Results
Both groups showed significant improvements in VAS and ODI scores at 1 and 3 months, with no significant differences between them. Vertebral height changes were also comparable.
Conclusions
Romosozumab-based conservative therapy may be a viable non-invasive alternative to vertebroplasty in treating acute OVCFs, offering similar short-term clinical and radiographic outcomes.
