Objective: The objective of this study is to examine the degree of concordance between clinical findings and lumbar magnetic resonance imaging (MRG) and lower extremity electromyographic (EMG) examinations in patients with lombar discal hernias.
Material and Method: Thirty four patients who had MRGs and EMGs and treated on in-patient basis were examined retrospectively. In patients the degrees of concordance between positive nerve traction tests, and clinical status as indicated by the presence of at least one neurological sign were explored. The patients were grouped clinically as definite, probable and possible cases with radiculopathy.
Results: In our patients degrees of correlations between clinical status and EMG or MRG were at identical level (48,2 %). However degree of concordance between EMG and MRG for the same clinical level was 38 percent. In 88 percent of 18 patients conforming with definite radiculopathy signs of physical examination and EMG were in concordance while for MRG the concordance rate was 77 percent. In this patient group degree of concordance for EMG and MRG was found to be 66 percent. In cases with probable radiculopathy, degrees of concordance between clinical findings and EMG or MRG were 75 and 62 percent respectively. Degree of concordance for both EMG and MRG was detected to be 56 percent.
Conclusion: In patients with symptoms of apparent radiculopathy, auxiliary diagnostic examinations have confirmed the presence of radiculopathy with a greater precision. However still MRG and EMG should be considered as complementary tests to physical examination in the assessment of lombar radiculopathy.
