I asked earlier on this board whether the fusion of lumbar spine would interfere with the results of the straight leg test. The reason I asked this question was I did not have any difficulty with the straight leg raise test and was bewildered because I am suffering with severe lower leg pain indicating nerve root involvement. I am fused L4-S1.
Well I researched and found out that the straight leg test does not show nerve compression L4 or above. Well guess what a test is used to show nerve ivolvement in the upper lumbar spine called the femoral test. The femoral test brought on my pain when the straight leg test was negative. At this rate I think I will have my problem solved before the doctors....lol
This was a relief to me as it does give an indication of where my immediate problem lies.
This is a test for irritation of higher nerve roots - L4 and above.
The patient is positioned lying face downwards, and with the knee flexed, the hip is lifted into extension. Lumbar root irritation tension may cause pain to be felt in the front of the thigh and the back.
