Management of Lumbar Spine Fractures
Diagnostic Evaluation
- The American College of Radiology recommends MRI of the lumbar spine without contrast as the diagnostic imaging of choice to evaluate fracture characteristics and exclude pathological causes 1
- Simple radiographs have insufficient sensitivity and should be complemented with cross-sectional imaging 2, 3
- The presence of neurological deficits requires immediate surgical referral 1
- Instability visible on imaging requires immediate surgical referral 1
- Suspected pathological fracture requires MRI with and without contrast, and possibly biopsy 1
Conservative Treatment
- The American College of Radiology recommends a minimum of 3 months of conservative medical treatment before considering intervention 4, 1
- Calcitonine for the first 4 weeks can reduce pain in acute fractures 1
- Non-steroidal anti-inflammatory drugs can be used according to tolerance 3
- Nerve block of the L2 root can be considered for referred pain 5
- Follow-up at 4-6 weeks is necessary to evaluate the response to initial treatment 1
Surgical Referral
- The American College of Radiology recommends immediate surgical referral for patients with neurological deficits 1
- Immediate surgical referral is also necessary for patients with documented spinal instability 1
- Pathological fracture suspected or confirmed requires multidisciplinary management (interventional radiology, surgery, oncology radiotherapy) 1
- Delayed surgical referral can be considered for patients with severe and progressive pain despite 3 months of conservative treatment 1
- Significant spinal deformity or progressive kyphosis requires delayed surgical referral 1
- Pulmonary dysfunction secondary to the fracture requires delayed surgical referral 1
Surgical Options
- The American Academy of Orthopaedic Surgeons recommends using autologous bone graft to optimize fusion rates, particularly in patients with compromised bone quality 6
- Posterior decompression and in situ fusion may be necessary for cases of severe instability or multiple fractures 6
Special Considerations
- The American Academy of Orthopaedic Surgeons strongly recommends against using vertebroplasty for osteoporotic fractures 1
