What are the treatment options for Sciatica (Lumbar Radiculopathy)?

From the Guidelines

Sciatica treatment typically begins with conservative approaches, including over-the-counter pain relievers, ice or heat therapy, and gentle stretching exercises, before considering more invasive options. The goal of treatment is to reduce inflammation, relieve pain, and improve quality of life. According to the American College of Physicians and the American Pain Society 1, the initial treatment approach should focus on self-care options, such as staying active, applying ice or heat, and taking over-the-counter pain medications like ibuprofen (400-800mg every 6-8 hours) or naproxen (220-500mg twice daily) for up to 10 days.

Some key considerations for treatment include:

• Gentle stretching exercises targeting the piriformis muscle, hamstrings, and lower back can provide relief - hold each stretch for 30 seconds and repeat 3-5 times daily.
• Physical therapy focusing on core strengthening and proper body mechanics is highly effective for long-term management.
• For more severe pain, prescription medications might include muscle relaxants like cyclobenzaprine (5-10mg three times daily) or short-term oral steroids like prednisone (tapering dose starting at 40-60mg daily).
• Most sciatica cases resolve within 4-6 weeks with these approaches.
• If pain persists beyond 6-8 weeks, epidural steroid injections may be considered, and surgery is typically reserved only for cases with significant neurological deficits or pain unresponsive to all other treatments.

It's essential to note that the treatment approach may vary depending on the underlying cause of sciatica, such as a herniated disc, bone spur, or piriformis syndrome. As stated in the guidelines 1, clinicians should provide patients with evidence-based information on low back pain, advise patients to remain active, and provide information about effective self-care options. Additionally, the guidelines recommend considering nonpharmacologic therapy with proven benefits, such as spinal manipulation, intensive interdisciplinary rehabilitation, exercise therapy, acupuncture, massage therapy, yoga, cognitive-behavioral therapy, or progressive relaxation, for patients who do not improve with self-care options 1.

Treatment Options for Sciatica (Lumbar Radiculopathy)

The treatment options for sciatica (lumbar radiculopathy) can be categorized into conservative and surgical management.

• Conservative management includes:
  • Mechanical physiotherapy (McKenzie) 2
  • Gabapentin 2
  • Transforaminal epidural injections 2, 3, 4
  • Bed rest and anti-inflammatory drugs 5
  • Low-back school and aerobic exercise program 5
• Surgical management is considered in cases with absolute indications such as cauda equina syndrome or marked progressive muscle weakness 5, or when conservative management fails 2, 6

Effectiveness of Treatment Options

• Conservative combination therapy (McKenzie physiotherapy, gabapentin, and periradicular injections) has been shown to be effective in reducing pain and improving quality of life in patients with sciatica due to lumbar disc herniation 2
• Epidural corticosteroid injections have been found to be effective in reducing short-term leg pain, disability, and overall pain in patients with sciatica 3
• Epidural steroid injection has been shown to be a simple, cost-effective, and minimally invasive treatment for sciatica, especially in the acute phase 4

Predictive Factors for Radical Treatment

• Factors predicting radical treatment after in-hospital conservative management of disk-related sciatica include taller stature, use of a lumbar support, more preadmission epidural injections, a positive straight leg-raising test, and a disk herniation diameter of at least 50% of the spinal canal diameter 6
• A positive straight leg-raising test and size of the herniation are significant clinical and radiological risk factors for radical treatment 6
