Recognizing specific characteristics of nonspecific low back pain

Area of Science:

• Orthopedics
• Pain Management
• Spinal Diagnostics

Background:

• Low back pain (LBP) presents diagnostic challenges, with referred pain syndromes and nerve root compression lesions being common etiologies.
• Differentiating between referred pain and radicular pain is crucial for effective LBP management.
• Combined spinal pathologies frequently occur, complicating diagnosis and treatment.

Purpose of the Study:

• To analyze the prevalence and characteristics of different low back pain causes over a 12-year period.
• To evaluate the diagnostic approach for distinguishing referred pain from nerve root compression.
• To assess the efficacy of a structured diagnostic and therapeutic strategy for low back pain.

Main Methods:

• Retrospective review of 1293 low back pain cases treated over 12 years.
• Analysis of common referred-pain syndromes (e.g., sacroiliac joint syndrome) and nerve root compression lesions (e.g., herniated nucleus pulposus, lateral spinal stenosis).
• Evaluation of coexisting lesions and incidental radiographic findings in conditions like spondylolisthesis.

Main Results:

• Sacroiliac joint syndrome and posterior joint syndromes were the most frequent referred-pain syndromes.
• Herniated nucleus pulposus and lateral spinal stenosis were the most common nerve root compression lesions.
• Referred pain syndromes occurred nearly twice as often as nerve root compression syndromes, with combined lesions in 33.5% of cases.

Conclusions:

• Accurate diagnosis requires distinguishing referred pain from radicular pain and recognizing coexisting lesions.
• Integrating diagnostic imaging with clinical presentation facilitates a rational therapeutic plan for low back pain.
• The outlined diagnostic approach aims to achieve excellent or good results in 84% of patients.
