From the Guidelines
A patient with suspected coccygeal fracture and cauda equina syndrome requires immediate surgical consultation and intervention, with prompt MRI imaging to confirm the diagnosis, followed by urgent surgical decompression within 24-48 hours to prevent permanent neurological damage. The management approach for such a patient should prioritize the relief of cauda equina compression to prevent long-term morbidity and mortality. According to the American College of Radiology Appropriateness Criteria, MRI lumbar spine without IV contrast is the preferred initial imaging study for evaluating suspected cauda equina syndrome due to its ability to accurately depict soft-tissue pathology and assess spinal canal patency 1.
While awaiting surgery, the patient should receive pain management with NSAIDs such as ibuprofen 400-600mg every 6 hours or opioid analgesics like morphine 5-10mg IV for severe pain. Corticosteroids (dexamethasone 10mg IV followed by 4mg every 6 hours) may be administered to reduce inflammation and spinal cord edema, as suggested by the clinical context of cauda equina syndrome 1. Key aspects of care include:
- Strict bed rest with log-roll precautions to minimize further injury
- Close monitoring of bladder and bowel function, with urinary catheterization if needed
- Regular neurological assessments to track changes in lower extremity strength, sensation, and reflexes
- Urgent surgical decompression to relieve cauda equina compression and prevent permanent neurological deficits, including paralysis, bowel/bladder dysfunction, and sexual dysfunction.
The coccygeal fracture itself is secondary to the neurological emergency and will be addressed during the surgical intervention. The primary goal is to alleviate the compression on the cauda equina to preserve neurological function and quality of life, emphasizing the importance of prompt and effective management in this medical emergency 1.
From the Research
Management Approach for Cocygeal Fracture and Cauda Equina Syndrome
The management of a patient with a suspected coccygeal fracture and cauda equina syndrome involves a comprehensive approach. Key aspects include:
- Early recognition of red flag symptoms such as bladder dysfunction, saddle anesthesia, and sciatica to prompt immediate investigation and treatment 2
- Immediate magnetic resonance imaging (MRI) within 1 hour of presentation to the emergency department for prompt diagnosis 2
- Urgent decompressive surgery to reduce morbidity and complication rates 2
Diagnostic Considerations
Diagnosis of cauda equina syndrome often involves:
- History and examination findings, although these may demonstrate poor sensitivity in isolation 3
- Imaging studies such as MRI or computed tomography myelography if MRI is not available 3
- Postvoid bladder volume assessments to assist in evaluation 3
Treatment and Outcomes
Treatment relies on surgical consultation and operative intervention for decompression 3. The long-term outcome of bladder or sphincter disturbances can be favorable, with almost normal voiding achieved in some cases, even if short-term recovery is poor 4. Physical therapy rehabilitation can also impact pain and function in patients with cauda equina syndrome 5. In cases of pediatric transverse sacral fracture with cauda equina syndrome, early decompression can help reverse neurological deficits 6
