脊髄終糸の過緊張によって発症した腰痛・下肢痛の診断 (TFT誘発テストについて) The diagnosis of tight filum terminale

Abstract

日常診察において, MRIなどの画像診断に異常がないにもかかわらず, 頑固な腰痛や下肢痛を訴える患者に遭遇することがある. それらの1つの原因に脊髄終糸の過緊張によって発症する脊髄終糸症候群 (Tight filum terminale : 以下TFT) があることが報告されている. 今回, TFTの診断の1つとして, 体幹および頚部の前屈動作により疼痛を誘発させるTFT誘発テストについて検討した. TFT患者群において, 立位TFT誘発テスト陽性率は96.4%, 座位TFT誘発テスト陽性率96.4%, 腰椎椎間板ヘルニア患者群において立位で33.3%, 座位で3.3%, 腰部脊柱管狭窄症で立位2.4%, 座位0%, 正常群で立位0.8%, 座位0%であった. これらの結果よりTFT誘発テストがTFTの診断に有用であることが示唆された.

Patients may complain of accusing persistent low back pain and leg pain even though imaging such as MRI does not reveal any abnormality. It has been reported that tight filum terminale (TFT) which is tethering of the spinal cord by stiff or TFT is one cause of such a low back pain. We evaluated a TFT provocation test in this study. The TFT provocation test yielded a positive rate of 96.4% in both a standing and sitting position in TFT patients. Regarding lumbar disc herniation, 33.3% showed positive results in a standing position and 3.3% in a sitting position. In lumbar canal stenos, positive results were abtained in 2.4% in a standing position and 0% in a sitting position. Aomng normal volunteers, positive results were obtained in a standing position in 0.8% of cases, but 0% in a sitting position. These results suggest that the TFT provocation test is useful in the diagnosis of TFT.
