The purpose of the femoral nerve pull test is to check if the patient has any irritation of the femoral nerve due to a herniated lumbar disc. This type of test may be performed if the physician suspects that the patient may currently have nerve root irritation due to a herniated lumbar disc. In performing this test, the physician will artificially create a tense position of the femoral nerve. At this point, if there is a compressive factor in the path of the femoral nerve, such as the presence of a lumbar disc herniation, pain in the area of the distribution of the bony nerve will be induced. If the patient feels pain in the groin and anterior thighs, a positive femoral nerve pull test is indicated. Once the positive sign is present, it indicates the possible presence of a lumbar disc herniation. Later, a series of ancillary tests, such as a lumbar spine CT or MRI, will further clarify whether the patient’s current symptoms are due to a herniated lumbar disc.
