From the Guidelines
The management of an L2 compression fracture should prioritize conservative treatment, including pain control, activity modification, and rehabilitation, as surgical interventions like vertebroplasty are not recommended as a first-line treatment 1. The initial approach to managing an L2 compression fracture involves a combination of pain control, activity modification, and rehabilitation.
- Pain management is crucial and can be achieved with analgesics such as acetaminophen (500-1000mg every 6 hours) or NSAIDs like ibuprofen (400-800mg three times daily), with short-term opioids like hydrocodone/acetaminophen (5/325mg every 4-6 hours for 1-2 weeks) considered if necessary.
- Bed rest should be limited to 1-3 days to prevent deconditioning, followed by gradual mobilization with appropriate bracing, such as a thoracolumbosacral orthosis (TLSO) brace, which may be prescribed for 6-12 weeks to provide spinal stability and reduce pain during healing.
- Physical therapy should begin within 1-2 weeks, focusing on core strengthening, proper body mechanics, and pain-reducing modalities.
- Calcium (1200mg daily) and vitamin D (800-1000 IU daily) supplementation supports bone healing, while osteoporosis medications like bisphosphonates may be indicated for patients with underlying bone density issues.
- Regular follow-up imaging at 6-12 weeks helps assess healing progress and determine when normal activities can be resumed. It's also important to note that while L2 nerve root blocks are mentioned as an option for treating pain associated with fractures at L3 or L4 1, the primary approach for an L2 compression fracture itself should focus on the aforementioned conservative management strategies, reserving more invasive procedures for cases with severe, unresponsive pain or significant neurological deficits.
From the Research
Management Approach for L2 Compression Fracture
The management approach for an L2 compression fracture typically involves a multimodal approach, starting with conservative therapy and potentially progressing to vertebral augmentation procedures if necessary.
- Conservative Therapy: This includes analgesic medication, medication for osteoporosis, physical therapy, and bracing 2, 3, 4.
- Vertebral Augmentation: Patients who are refractory to conservative management may be candidates for vertebral augmentation through either vertebroplasty or kyphoplasty 2, 3, 5, 6.
- Pain Management: Evidence suggests that vertebral augmentation, especially some of the newer procedures like balloon-assisted kyphoplasty, have the potential to dramatically reduce pain and improve quality of life 3, 6.
- Procedure Selection: The choice of procedure depends on various factors, including the severity of the fracture, the patient's overall health, and the presence of any contraindications 5, 6.
- Timing of Intervention: Patients with severe pain refractory to nonoperative management who are offered intervention within 3 weeks may benefit from vertebral body augmentation 5.
Key Considerations
- Risk Factors: Understanding the risk factors for vertebral compression fractures, such as osteoporosis, is crucial in managing these patients 6, 4.
- Clinical Evaluation: A focused history and exam can identify patients likely to benefit from vertebral body augmentation 5.
- Imaging Studies: Magnetic resonance imaging can help identify patients with bone marrow edema who may benefit from injection of cement into the fractured vertebral body 5.
- Complications: While vertebral augmentation procedures are generally safe, there are potential complications, and the risks and benefits should be carefully considered 3, 6.
