Objective
Facet joint injections (FJIs) and medial branch blocks (MBBs) are commonly used interventions for chronic spinal pain, but their comparative effectiveness remains unclear. This meta-analysis aimed to compare the pain relief, functional improvement, complications, and patient satisfaction associated with FJI and MBB.
Methods
A systematic review and meta-analysis of randomized controlled trials and observational studies were conducted. Primary outcomes included pain relief (numerical rating scale) and functional improvement (Oswestry Disability Index [ODI]/Neck Disability Index). Secondary outcomes assessed adverse effects and patient satisfaction. The differences in characteristics between patients who were readmitted and those who were not were identified and analyzed using the Review Manager software.
Results
FJI resulted in lower pain and ODI scores compared to MBB, but the differences were not statistically significant. However, patient satisfaction was significantly higher in the FJI group (odds ratio, 1.81; 95% confidence interval, 1.02–3.24; p=0.04). Additionally, FJI had fewer adverse effects than MBB.
Conclusion
Both FJI and MBB are effective for chronic spinal pain, but FJI may be preferred for patients seeking immediate pain relief with fewer complications. Further high-quality studies are needed to refine treatment guidelines.

We report a case of a solitary osteochondroma as a dumbbell tumor compressing the spinal cord and its surgical strategy. The patient is a 16-year-old female with longstanding posterior neck pain and left arm abduction weakness. She was examined by plain X-ray, three-dimensional-computed tomography, magnetic resonance imaging, and vertebral angiography. The analyses indicated a calcified extradural mass compressing the cord in the C3-4 portion extending into the neural and vertebral foramen with eroded vertebral body. The tumor was successfully excised using a modified combined anterior and posterior approach. Histopathologic study of the resected material confirmed the diagnosis. The postoperative assessment was followed by clinical and radiologically therapy for 5 years after surgery. Osteochondroma arises from enchondral bone but it rarely involves the spine, especially not as s dumbbell type. In this patient, the tumor may have arisen from the neural arch and extended into the extradural and extraforaminal space over a long period. We successfully removed the dumbbell tumor with a combined anterior oblique and posterior approach. However, further observation is essential because of the possibility of recurrence and sarcomatous change.
