Summary
Juxta-facet cysts, including ganglionic and synovial types, rarely cause nerve root compression. Surgical removal offers significant relief from pain and neurological deficits in most patients.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Radiology
Context:
- Juxta-facet cysts (ganglionic and synovial) are uncommon causes of nerve root compression.
- Magnetic resonance imaging (MRI) is the primary diagnostic tool.
- Surgical excision is the definitive treatment, though conservative measures offer temporary relief.
Purpose:
- To evaluate the incidence, clinical presentation, and surgical outcomes of juxta-facet cysts causing nerve root compression.
Summary:
- A retrospective study identified 24 symptomatic juxta-facet cysts (10 ganglionic, 14 synovial) in 19,107 lumbar and thoracic operations.
- Cysts were most common at L4-L5.
- Patients presented with radicular pain (7) or neurological deficits (17).
- Surgical resection, often combined with discectomy, was performed in 14 cases.
- Follow-up averaged 26.6 months for 23 patients.
Impact:
- Surgical treatment resulted in significant symptom improvement.
- 89% of patients with paresis and 73% with sensory deficits experienced resolution.
- 74% of patients achieved complete pain relief post-operatively.
