Radiological diagnostic of lumbar spondylolysis

Area of Science:

• Orthopedics
• Radiology
• Spinal Imaging

Background:

• Spondylolysis is a bone disruption occurring at the vertebral arch's isthmus.
• Accurate diagnosis is crucial for managing low back pain and spinal conditions.

Purpose of the Study:

• To review and compare diagnostic methods for spondylolysis.
• To highlight the efficacy of advanced imaging techniques in spondylolysis diagnosis.

Main Methods:

• Review of diagnostic modalities including plain radiography, computed tomography (CT), magnetic resonance (MR), and scintigraphy.
• Evaluation of different radiographic views (A-P, lateral, dynamic, oblique).
• Assessment of CT with multiplanar reconstruction (MPR) and 3D reconstruction.

Main Results:

• Plain radiography is useful for initial low back pain assessment, with dynamic views aiding stability assessment.
• CT, especially with MPR and 3D reconstruction, demonstrates the highest diagnostic value for spondylolysis and associated complications.
• MR imaging is best suited for evaluating soft tissues and neurological complications; scintigraphy has limited practical importance.

Conclusions:

• CT with advanced reconstruction techniques provides reliable diagnosis of spondylolysis and related pathologies.
• The choice of imaging modality should be guided by the specific diagnostic question, prioritizing CT for bony detail.
