- G57.00 Lesion of sciatic nerve, unspecified lower limb
- M54.16 Radiculopathy, lumbar region
- M54.17 Radiculopathy, lumbosacral region
- M54.3 Sciatica
- Low back pain radiating into the lower extremity (LE)
- Can result from lateral lumbar/sacral spine nerve root compression or piriformis syndrome
- Diagnosis made by clinical examination
- Dermatome/myotome pattern compared to peripheral nerve distribution
- Reproduction of symptoms
- Presence of leg pain significantly increases the odds of condition becoming persistent
- Most individuals will have sciatica symptoms at least once in their lifetime
- Pain radiating down the leg(s), below the knee, along the distribution of the sciatic nerve
- Usually related to mechanical pressure and/or inflammation of lumbosacral nerve roots
- Can be with or without lower back pain
- Diminished sensation, motor control, and reflexes in the distribution of the involved nerve
- Difficulty maintaining sustained sitting postures secondary to back and leg pain
- Inability to sleep
- Weakness with lifting, prolonged standing
- Loss of movement or feeling in the LE
- Difficulty with movements secondary to pain such as driving or twisting
Possible Contributing Causes
- Postural changes including weakness of core musculature and tightness of hip flexors, external rotators, and hamstrings
- Prolonged occupational stresses
- Disc pathology, other sources of nerve root compression
- Peripheral nerve impairment
- Hip pathology with radiating pain pattern
- Spinal tumor
- Lyme disease
- Peripheral neuropathy
- Paraspinal muscle hypertonicity
- Degenerative disk disease
- Sacral or pelvis dysfunction
- MRI helpful in diagnosis to visualize compressed or inflamed nerve root
- X-ray/plain film radiograph helpful if osteophyte located in intervertebral foramen
- CT scan to show herniation compressing the spinal canal/nerves
- Electrodiagnostic/nerve conduction testing can assist to determine a specific impaired nerve function
- Surgical consult if myelopathy is suspected
- Corticosteroid injection if ...
