Treatment for Baastrup's Disease (Kissing Spine Syndrome)
The treatment for Baastrup's disease should begin with conservative measures, including anti-inflammatory medications and physical therapy, progressing to interventional procedures such as steroid injections before considering surgical options for refractory cases. 1, 2, 3
Diagnostic Criteria
Before initiating treatment, confirm the diagnosis with:
- Clinical presentation: Low back pain that worsens with extension and improves with flexion
- Imaging findings: Close approximation of adjacent spinous processes (typically at L4-L5)
- Physical examination: Pain exacerbated by finger pressure at the affected level
- Diagnostic test: Positive response to local anesthetic injection between spinous processes 4
Treatment Algorithm
First-Line Treatment (Conservative Management)
Non-pharmacological approaches:
- Physical therapy focusing on core strengthening
- Posture correction to reduce excessive lordosis
- Activity modification to avoid spine extension
- Heat/cold therapy
Pharmacological management:
- NSAIDs for pain and inflammation
- Muscle relaxants for associated muscle spasm
Second-Line Treatment (Interventional Procedures)
- Steroid injections:
- Subcutaneous or interspinous steroid injections
- Target: Space between affected spinous processes
- Frequency: Can be repeated if initial response is positive but temporary 2
Third-Line Treatment (Surgical Options)
For patients with persistent symptoms despite conservative management and injections:
Minimally invasive approaches:
- Full-endoscopic interspinous plasty
- Resection of marginal osteophytes
- Removal of inflamed tissue
- Recovery of physiological gap between spinous processes 4
- Full-endoscopic interspinous plasty
Open surgical options:
- Excision of the interspinous bursa
- Partial spinous process resection (osteotomy)
- Spinal fusion may be considered in cases with associated instability 5
Special Considerations
- Elderly patients: Higher prevalence in patients over 70 years; conservative management should be emphasized
- Associated conditions: When Baastrup's disease coexists with spondylolisthesis or spinal stenosis, treatment should address both conditions 5
- Neurological symptoms: If intraspinal synovial cysts are present causing neurogenic claudication, surgical decompression may be necessary
Treatment Efficacy
- Conservative treatment and steroid injections provide significant relief in many patients
- Full-endoscopic interspinous plasty has shown promising results with VAS score improvements from 7-8 to 1-2 and ODI improvements from >70% to approximately 30% 4
- Surgical interventions should be reserved for cases refractory to conservative management
Monitoring and Follow-up
- Regular assessment of pain levels and functional status
- Follow-up imaging to evaluate structural changes and potential recurrence
- Continued home exercise program to maintain core strength and proper posture
The management of Baastrup's disease requires a stepwise approach, starting with conservative measures and progressing to more invasive options only when necessary to improve quality of life and reduce morbidity.
