From the Guidelines
I strongly advise against routine imaging, including lumbar spine x-rays, for this 56-year-old male prisoner with nonspecific low back pain, as it is not associated with improved patient outcomes and may expose him to unnecessary ionizing radiation 1. Instead, I recommend a comprehensive approach focusing on non-pharmacological interventions and physical therapy.
- The patient should be provided with a bed wedge to help with spine decompression by creating a slight incline during rest, potentially relieving pressure on intervertebral discs and nerve roots.
- Physical therapy is essential for strengthening core muscles, improving flexibility, and teaching proper body mechanics to prevent future pain episodes.
- The patient should start with gentle exercises focusing on core stabilization and gradually progress as tolerated.
- For pain management, consider starting with acetaminophen 650-1000mg every 6 hours as needed, or ibuprofen 400-600mg three times daily with food if there are no contraindications.
- The patient should be advised to maintain proper posture, avoid prolonged sitting, and incorporate regular movement throughout the day.
- Follow-up evaluation should occur in 4-6 weeks to assess treatment response and modify the plan if needed, as patients with acute low back pain generally experience substantial improvement in the first month after initial presentation 1.
From the Research
Diagnosis and Treatment of Low Back Pain
- The patient's complaint of low back pain is a common condition, with a prevalence of 10-30% in the general US adult population annually, and a lifetime prevalence of 65-80% 2.
- A thorough history, physical exam, and diagnostic testing are essential for accurate diagnosis and identification of the patient's pathophysiology 2, 3.
- The etiologies of low back pain include myofascial pain, facet joint pain, sacroiliac joint pain, discogenic pain, spinal stenosis, and failed back surgery 2.
- For chronic low back pain, a multidisciplinary approach to treatment is most effective, and can include multimodal medical, psychological, physical, and interventional approaches 2, 3.
Imaging and Diagnostic Testing
- Routine imaging is not recommended for chronic low back pain, but may be indicated when red flags are present, there is a neuromuscular deficit, or if pain does not resolve with conservative therapy 3.
- The use of CT scans or X-rays, such as the ordered X-ray of the lumbar spine, can help determine the most likely anatomical nociceptive source, thereby enhancing the therapeutic approach by targeting a specific lesion 4.
- However, the added diagnostic value from repeat imaging, such as CT scans, performed within 2-3 years is rare in patients suffering chronic or recurrent low back pain or radiculopathy, suggesting that repeat imaging should be considered only in patients with progressive neurologic deficits, new neurologic complaints, or signs implying serious underlying conditions 5.
Treatment and Management
- Nonpharmacologic treatment is first-line management for chronic low back pain, and may include therapies such as counseling, exercise therapy, spinal manipulation, massage, heat, dry needling, acupuncture, transcutaneous electrical nerve stimulation, and physical therapy 3.
- The prescription of PT for this patient is a suitable treatment option, as physical therapy is a recommended nonpharmacologic treatment for chronic low back pain 3.
- The use of a bed wedge for spine decompression may also be beneficial, although patients with chronic low back pain should avoid bed rest 3, 6.
