The mannequin sign is a reliable clinical indicator for diagnosing sciatica caused by lumbar disc herniation. This sign demonstrates high reproducibility and sensitivity, aiding in accurate patient assessment.

Area of Science:

  • Orthopedics
  • Neurology
  • Diagnostic Medicine

Background:

  • Sciatica is often caused by lumbar disc herniation.
  • Accurate diagnosis is crucial to avoid unnecessary investigations and treatments.
  • The 'mannequin sign' is a clinical observation associated with sciatica.

Purpose of the Study:

  • To critically appraise the mannequin sign for validating patients with sciatica symptoms.
  • To assess the diagnostic utility of the mannequin sign in lumbar disc herniation.

Main Methods:

  • Prospective observational study of 65 patients with confirmed lumbar disc herniation.
  • The mannequin sign was assessed for reproducibility by two clinicians.
  • Magnetic resonance imaging (MRI) confirmed lumbar disc herniation and nerve root impingement.

Main Results:

  • The mannequin sign exhibited 100% reproducibility among clinicians.
  • The sign demonstrated 80% sensitivity in diagnosing lumbar disc herniation with nerve root impingement.
  • The study included patients with L4-L5 and L5-S1 disc herniations.

Conclusions:

  • The mannequin sign is a highly reproducible and sensitive clinical finding.
  • Clinical examination, including the mannequin sign, can improve diagnostic accuracy for sciatica.
  • This sign may help reduce misdiagnosis, unnecessary tests, and inappropriate surgery.
