Fractures of the spine below the cord, accompanied by symptoms indicative of cauda equina injury, necessitate immediate surgical attention. The decision to operate or adopt an expectant approach hinges on accurate diagnosis of the spinal cord's condition. Partial lesions and injuries to the Cauda equina generally require operative intervention. Each case must be evaluated individually considering complicating factors such as shock and concurrent injuries elsewhere in the body.
Operative objectives include correcting deformity, decompressing the spinal cord, suturing nerves, and treating compound fractures. The extent of sensory and motor loss determines the severity of the injury; however, delaying diagnosis can worsen partial lesions due to pressure myelitis or other degenerative processes within the cord. Some surgeons advocate for spinal canal opening in cases with suspected partial lesions to relieve pressure.

Spinal decompression can be achieved through laminectomy or osteoplastic resection. Laminectomy involves a median incision and careful dissection of muscles from spines and laminae to expose the spinal cord for inspection and pressure relief. Osteoplastic resection uses a U-shaped incision, dividing ligaments transversely between vertebrae below the injury.
After surgery, maintaining spine fixation and addressing complications like bed sores or urinary tract infections is crucial. The prognosis varies based on the extent of spinal cord damage; uncomplicated fractures have good outcomes but injuries to the cord are often fatal within months due to secondary conditions.
Key Takeaways
- Immediate surgical intervention is necessary for spinal fractures below the cord with cauda equina symptoms.
- Partial lesions and injuries to the Cauda equina generally require operative treatment.
- Maintaining spine fixation post-operation is crucial alongside symptomatic treatment of complications.
Practical Tips
- Accurate diagnosis of spinal cord condition is critical before deciding on surgical intervention.
- Post-operative care should focus on preventing bed sores and managing urinary tract infections.
- Use of specific techniques like laminectomy or osteoplastic resection depends on the injury's location and severity.
Warnings & Risks
- Delaying diagnosis can worsen partial lesions due to pressure myelitis or other degenerative processes within the cord.
- Permanent catheterization should be avoided as it may lead to urethral complications over time.
Modern Application
While surgical techniques have advanced significantly since 1915, the principles of spinal fracture treatment remain relevant. Immediate diagnosis and intervention are still crucial for managing cord injuries effectively. Modern imaging technologies like MRI provide more accurate diagnoses, while advancements in surgery offer better outcomes.
Frequently Asked Questions
Q: What is the primary reason to perform a laminectomy or osteoplastic resection?
These procedures aim to relieve pressure on the spinal cord and correct deformities caused by fractures. They are critical for decompressing the spinal canal and examining the condition of the spinal cord and nerves.
Q: Why is accurate diagnosis crucial before deciding on surgical intervention?
Accurate diagnosis helps determine whether the injury is complete or partial, which influences the decision to operate. Delayed diagnosis can worsen partial lesions due to pressure myelitis or other degenerative processes within the cord.
Q: What are some common complications after spinal surgery?
Common complications include bed sores, urinary tract infections, and fecal impaction. Proper post-operative care is essential for managing these issues effectively.
